Superchips Flashpaq for JK
 

My results from Superchip Flashpaq reprogram as promised in other thread in main forum. I thought I would post it here for those that don't wonder out of the JK forum ..

My JK specs.
2008 Unlimited Sahara 3.8L V6 Auto 90,000klm
Factory 3.73 gears
35x12.50x16 GY Duratracs (actually measure 34")
3.5" front lift, 2.5" rear lift
relocated exhaust no motor mods other then the Flashpaq

1027klm since Flashpaq install
Install info
- 87 octane tune
- recal for tires/speedo
- removed Rev limiter (factory was set at 5280rpm)
- removed Speed limiter (factory was set at 140kph) ..
- throttle response - set to Superchips setting

Observations:
- Throttle response is much better, not sluggish anymore.
- shifting in auto is firmer and more accurate (like it should have been from the factory)
- does not hunt for gear as much, downshifts sooner.
- more torque in the bottom
- more passing power as the Rev and Speedo limiters were removed.. Yes I had it over 160KPM passing the big rigs with no problem.
- seems to get up to speed quicker

Conclusion:
Should have done this a long time ago. So much more fun to drive. Highly suggest this product. I did this on my 98 RAM with the same great results 7 years ago.
Bonus = better gas mileage.
On a 500klm road trip yesterday I averaged 12.2L/100klm (19.6mi / USgl. or 23.5mi / Imp gallon) with O/D off Cruise Control set to 110klm when on the highway. Thats just shy of 700klm for the 85liter tank in the Unlimited. Currently at 340klm I'm at 1/2 tank.
At 110kph the engine runs in its sweetspot at 2500rpm
Overall observation is that the Flashpag takes time to learn your driving habits and is still tweaking itself in mine at just over 1000klm since reprogram. It seems to get better every time I drive it. Once it has settled in I will update this post again then try the 91 Octane tune.

With this tuner you should see an easy consistent 2mpg increase in mileage. This mileage increase will vary dependent on your driving style of course.
If you are still on stock tires there is no reason you shouldn't get under 10L/110klm hwy. Remember I'm getting 12.2L/100klm on 35s and 3.73 gears O/D off. If I swap out to 5.13 gears and can then use O/D I can prob pull out another mpg or two.

Re: Superchips Flashpaq for JK
 

Thanks for sharing your findings. I still have a hard time wrapping my head around the "higher rpm getting better mpg".

I'm going to have to turn off o/d and see it for myself. Right now at 110kph my rpm is 1900, turning off the o/d should put me around the 2500-2600rpm range.

Re: Superchips Flashpaq for JK
 

All you can do is run a full tank with O/D off and see for yourself. The engine runs so much smoother at 2500rpm.
Running O/D off does not net better mileage with stock size tires. Not sure it will even make much difference with narrow 33s but definitely makes a difference with wider 33s and 35s.

Re: Superchips Flashpaq for JK
 

JTPhoto JK,

Thanks for the very detailed write up, best I've seen on the subject. I'll keep an eye out for your updates as you get some 'run time' on this tune. Considering our two Jeeps are the same (3:73's and auto) your MPG doing pretty good...I'm bone stock and I'm seeing the 9.5L /100 KM as an average...bone stock....considering your mods you are doing good!

Re: Superchips Flashpaq for JK
 

Definately going to "chip-up" both my 09 Rubicon and my wifes Wrangler X. Both are two door but hers is auto and mine a 6 speed. Hers has 285/70/17 GY and mine is stock with 255/75/17 BFG. I don't even try to drive hers anymore with the overdrive on as it won't keep speed and its constantly backshifting. She gets not quite 400k per tank and I'm getting near 100k more per tank. Interesting....

Re: Superchips Flashpaq for JK
 

As per Superchips forum
87 octain tune +16hp +13torque
91 octain tune +21hp. +30torque

Don't forget to go into the advanced settings and set throttle response, rev limiter, and speedo limiter.

Re: Superchips Flashpaq for JK
 

I'm going to try Googleing Superchips and see where I can get one...if I have no success I'l ask you for the info.
Thanks !

Re: Superchips Flashpaq for JK
 

UPDATE: I've run a few tanks through on 87 Octane tune and so far it is a welcome change. I am currently averaging between 12 - 12.8L /100klm depending on how much city driving I do. Throttle response off the stop is pretty surprising.
Today I changed it up and filled up with 91 Octane and left the tune at 87. Wow, now there is a noticeable difference and I haven't even programmed it for 91 Octane yet. The torque curve for 91 Octane tune is suppose to climb quicker then the 87 tune and much quicker then stock. I will have to try it for a tank or two to see if the cost factor equates to a mileage benefit.
More later...

Re: Superchips Flashpaq for JK
 

I am really interested in the Flashpaq.

Is there a way to put it back to factory setting? Also, is it user friendly?

Where do you get one of these?

Re: Superchips Flashpaq for JK
 

Very simple to put back to stock at anytime. They can be purchased through any Jeep accessory retailer. Northridge or JustJeeps in Canada or Quadratec and 4wd parts in the US.

Re: Superchips Flashpaq for JK
 

Thanks...I am going to look into it.

Re: Superchips Flashpaq for JK
 

OK very quick update. Since fill up with 91 octane (still on 87 tune) I already have 75klm and its just down to the full mark, that is about 15-20 klm more then I usually get. But, alas, I am too impatient to wait any longer. As much as this 91 octane on the 87 tune looks like its worthwhile I am itching to try the 91 tune.

Ok check in - 91 tune around town there seems to be a little more torque in the bottom end in the 1500 rpm range. Seems to pull a little better, operative work here folks "a little better" not Hemi better.. LOL

Stay Tuned! LOL

Re: Superchips Flashpaq for JK
 

Whhooo I love this 91 Octane tune. Jury is out to whether its going to balance out cheaper or cost more to run but it runs soooo nice. I can feel the extra pull in the bottom end. Again, not a racecar or a Hemi but much better then stock.
I'll try the tow tune next week as this seems to be the preferred tune for JKU's with bigger tires.

I would also like to add at this time that the BIGGEST changes the Flashpaq makes is when you bump up the Rev Limiter, Speedo Limiter and change the throttle response. The JK is a totally different animal on the highway and passing at 160kph (O/D OFF in my case) is not a problem.

Re: Superchips Flashpaq for JK
 

one more questions....for the nite....

How is this different from the AEV Procal?

Re: Superchips Flashpaq for JK
 

The ProCal allows you to reset your tires size or gear change to correct your speedo and they do a few other things like allow you to set TPMS levels and a few other small things that you can actually set without it.
- It DOES NOT let you reprogram your engine for optimal performance, i.e. 87 octane tune, 91 Octane, 93 Octane, Tow tune, mileage XS tune, Crawl tune. .
- It DOES NOT allow you to adjust throttle response, rev limiter, or speed limiter.
- It DOES NOT allow you to adjust transmission shift points. (This feature is an extra download for a small fee)

The Superchips Flashpaq or Diablo Predator do all of this plus more.

Re: Superchips Flashpaq for JK
 

Thanks....i suspected that the ProCal was missing something given the price point but wasn't sure.

I suspect that when tuning for performance, the Flashpaq is playing with the A/F ratio....did you have any issues i.e. any knocking?

Re: Superchips Flashpaq for JK
 

There are many things taken into account with the performance tunes including engine timing as well as air/fuel ratios.
No knock or ping issues at all..

Re: Superchips Flashpaq for JK
 

Thanks JT...if only you lived closer or I lived closer I would love to see your JK.

Re: Superchips Flashpaq for JK
 

Here the Superchips page with more info for you...

Re: Superchips Flashpaq for JK
 

Just a quick Check in..

91 Octane tune is fun to drive, pulls good on hills, but the mileage is not as good. I will give it another 100klm or so to see what happens. If mileage is not a concern you will love this tune.

Re: Superchips Flashpaq for JK
 

Superchips does not support 2011 Jeeps....yet! I guess I will have to wait.

Re: Superchips Flashpaq for JK
 

Just filled up , calculated at 16.6 mpg 14.2l/100klm mixed city hwy with 91 octane fuel and 91 octane tune. Not bad considering I have been stepping on it a little here and there to see how it pulls. No doubt I will easily get 18-19mpg if I drive conservatively.

Re: Superchips Flashpaq for JK
 

UPDATE:
235klm into this tank of premium(91) on 91 Octane tune and I really love how the motor feels. My only problem with it is that there are alot of fuel stations in the outlying areas that don't carry 91 Octane and I may not always have the tuner with me to tune it back down to 87Octane. Fuel mileage was also good on the 91 Octane performance tune but not as good as running 91 on the 87 performance tune.

But, alas I must try the other tunes so on to the TOW Tune.. So, in town TOW Tune is snappy (not like the 91 octane performance tune, but acceptable and still way better then stock). On the highway passing is not an issue and no probs climbing hills. The biggest difference I noticed is the shift program is different (much better then stock). It seems even smoother then the performance tunes and holds onto the gears a little longer before upshift and shifts down a little sooner when climbing hills. I'll finish off this tank with the Tow tune and see what the overall mileage looks like.

Re: Superchips Flashpaq for JK
 

I notice this after turning o/d off. So can only imagine how good it would be with the tune. Thanks for sharing.

Re: Superchips Flashpaq for JK
 

Definitely! I run with O/D OFF 90% of the time. Eventually I will regear to 5.13..

Roadtrip to the beach tomorrow.. We'll see how the Tow Tune is on the highway for a longer distance.

Re: Superchips Flashpaq for JK
 

UPDATE:
Full tank of 91 Octane on Tow Tune - mixed but mostly highway 100kph using cruise where possible. Calculated mileage 12.9L/100klm or 18.2 mpg (dash computer average said 12.6L/100klm).

Conclusion, so far I prefer the Tow Tune overall for a good mix of performance and economy.

FYI if your mileage is 1L/100klm less when using premium fuel over regular then you are breaking even $ wise.

Mileage on Premium = 12.9L/100klm VS Mileage on regular = 13.9L/100klm = same dollar value..

My findings to date: Remember this with 35" tires w/ 3.73 gears running with O/D OFF
Average mileage 87 Octane Performance Tune on 87 Octane 14-14.2L/100klm (16.8mpg)
Average mileage 87 Octane Performance Tune on 91 Octane 13.8L/100klm (17mpg)
Average Mileage 91 Octane Performance Tune on 91 Octane 13.2L/100klm (17.8mpg)
Average Mileage Tow Tune on 91 Octane 12.9L/100klm (18.2mpg)

Re: Superchips Flashpaq for JK
 

FYI for those not sure whether a tuner is worth it...

3.6L Pentastar = 285hp 260ftlb torque @ engine

3.8L V6 = 205hp 237ftlb torque @ engine

Dyno charts with Superchips 91 Octane Performance Tune 3.8L show Gains of 21rwhp and 30ftlb torque rearwheel. realize that these show at the rear wheel gains which would be even higher if measured off the engine as the factory specs above are. Which means the 3.8 with this tune does put out more torque then the stock 3.6L with a curve almost as flat, at least until a tuner is available for the 3.6L.

Re: Superchips Flashpaq for JK
 

You're B/E analysis should be taken with a grain of salt. For a 7% decrease in fuel consumption may/may not yield a breakeven $. It depends on the gas station. For example, Costco reg = $119.9, while 91 = $127.9, that's a 6.7% price variance in favour for 91. However if you go to Shell at 1292 Dupont (according to TorontoGasPrices.com), reg = $123.2, while Premium = $135.9,, which yields a price variance of 10% in favour of reg. My analysis could be flawed in that Shell's premium might be different from Costco (does anyone know what Shells Premium is?).

BUT your 91 Octane Performance Tune on 91 Octane with tow tune looks really good.
I can't wait till they have the pack for the 2011.

Re: Superchips Flashpaq for JK
 

My figures are based on the prices in Thunder Bay where 91 octane is always .10 / litre more then regular (87 octane) no matter what station you fill up at. $1.30 reg $1.40 prem at present.
So that being said:
64L Premium at $1.40/L = $89.60
$89.60 / $1.30/L= 68.92L regular
Therefore: 64L of premium is = in dollar value to 68.92L of Regular
496klm traveled on 64L premium = 12.9L/100klm or 18.2 mpg
496klm traveled on 68.92L regular = 13.9L/100klm or 16.9 mpg

Difference of roughly 1L/100klm or 1.3mpg US..

Re: Superchips Flashpaq for JK
 

Yeah I was going by TorontoGasPrices.com. I don't know how accurate that report is. I never fill up on Premium. Come to think of it, I am going to try Premium next time to see if I get better fuel economy without the SC.

Re: Superchips Flashpaq for JK
 

If you are running stock tires you probably won't see a gain until the cold weather comes. I saw most of the gains in cold weather, however, the programmer really takes advantage of premium all year round.

Re: Superchips Flashpaq for JK
 

I'm new here in this forum and everything i read is really nice.

Re: Superchips Flashpaq for JK
 

Pulled the Big utility trailer full of stuff to the dump on Saturday. Tow tune really helps climbing the hills by kicking the transmission down sooner as not to loose too much speed/rpm.. It also holds the gear longer before upshift.. I can see where a gear change with this tuner would make even towing a trailer enjoyable.

Re: Superchips Flashpaq for JK
 

OK its been 2 weeks with the Tow Tune and just over a month with the the programmer. Tow tune on 91 Octane is definitely my favorite. Mileage is a consistent 18-19mpg mixed. Throttle is very responsive now more so then when first programmed. This is one of the great things about this tuner, it has a self learning throttle control program within the programming. So far so good, the only thing we need now is a gear change. The programmer is not a replacement for proper gearing but it does make driving on 35s more fun..

Re: Superchips Flashpaq for JK
 

Not bad mileage at all. My mpg seems to be tough to nail down, off roading it kicks the snot out my average. Normal driving (mixed city/highway) I'm guessing about 15-16 mpg here.

Re: Superchips Flashpaq for JK
 

I have only had my jeep for a few weeks but I feel I can talk about fuel with some intelligence. There is a very big difference in fuels. I am not sure about all fuels out there but I run shell in everything I drive all the time and always get better milage. The reason for this is shell 91 has no ethanol. Although ethanol is great for using less crude it does have some disadvantages. The biggest of which for your ( or any vehicle) to create the same amount of power it needs to burn 30% more ethanol then non ethanol fuel. Now I am bad at math but using a fuel with 10% -20% ethanol your vehicle will have to burn more of that fuel to create the same power as non ethanol fuel. I have seen pumps with " may contain up to 20% ethanol on them. On my stock jk 4 door with me, the wife, dog and 2 kids loaded up got 13.2L/100km on the last tank of shell. That in included 2.5 hours of 1st gear wheeling on rocks and in mud ( did not think I would make it out). I then filled up again and so far am at 327.9 km and just over 1/2 tank. Now that is driving just mr and 80% 2 lane highway average speed somewhere around 95km or so.

Re: Superchips Flashpaq for JK
 

You're lucky that you have a station that can supply you with no ethanol gas. Not all Shell stations have 100% gas (i could be wrong), but getting to a Shell station for me is a PITA. But you're right, more ethanol = less fuel economy.

Re: Superchips Flashpaq for JK
 

Oh I should also say that I have a manual trans. I was unaware that not all shells were no ethanol. And the 0% eyhanol is only on their 91. But I find ( in the Peterborough area) that even their 87 and 89 have less ethanol then the others. I out alot of km's on but most of it is between Peterborough, Bancroft and all places in between.

Re: Superchips Flashpaq for JK
 

Are you running with bigger tires? If not you need to get a programmer to maximize that 91 octane, 100% petroleum fuel that you speak of. 13.2L/100klm is not good for stock, you should be getting 11.5 to 12.5L/100klm. I easily get 13.2L or better with 35" tires, stock gears, and a programmer. Factory tuning is not designed to run 91 Octane so you are basically wasting your money. I have tracked my 08 Jeep JKU mileage for 3.5 years and premium only makes a slight difference in colder (below 0) weather..

Re: Superchips Flashpaq for JK
 

I really need that programmer. I am hovering high 15L/100km to low 16L/100km (my own calc, not the Jeeps) on 33 Mickey Thompson Baja. I might need to switch back to my stock rims/rubbers to see if there's an improvement, which I think their would be.
