Re: Possible Trolls?
So he has the Hemi with the MDS system in it like they put in the Jeep?
If so then the article I read must have been out of date. It said the MDS wasn't used in the pickups because of load and reaction time issues. It would be interesting to know what he modified for the gain and if it was a top or bottom end gain. Maybe there is a way to shut the sucker down and stay in V8 mode? I come from the muscle car days too and something like that really messes with the 'Hemi' idea. Wayyyy too many parts and crap. Sounds like there isn't even a gas pedal cable or linkage. All electronic. No more shoe lace trail fixes. LOL! Man, next they will be using microsoft in the ECU. Mike Matt Macchiarolo wrote: > > Not when he punches it.

Re: Possible Trolls?
I believe so. I imagine there is a way to re-flash the ECM to kill the MDS
system. In a couple years the performance chips will probably be available to do this.

Would be easier to believe it was because of no mileage standards in pickups...yet. As for the reaction time, the switch back to 8 cyl mode is under 3/4 of a rev, making it under half of an ignition cycle. Haven't seen any mentions of hemi hesitation in any of the road tests of the hemi GC...which turns mid 6's to 60 in any of the tests I've seen. > > It would be interesting to know what he modified for the gain and if it > was a top or bottom end gain.

I come from the old muscle car era as well, having had the pleasure of owning more than one engine over 7 liters with compression ratios in in the 12:1 range. Although the thundering torque was a lot of fun, a much smaller modern engine with modern engine management systems does much better except in dim memories. Granted it was a lot easier to hop up the old rat motors, wedge heads, etc. without a PhD, but then again you actually *had* to do this to get anywhere near the advertised performance except on a very few purposely underrated homologation special models. > > Man, next they will be using microsoft in the ECU. > Hmmm, ya think that is what is causing the hesitation? |
