It was just a couple years ago, there was a rule proposal to ban race gas in stock class cars - since all cars w/ stock DME/Chips/Timing were designed to run on pump gas, only cheaters would need to run race fuel (?). That didn't pass. But now fast forward a couple years and we have swung fully around - now we adopted a rule that allows us to custom tune an ignition chip to maximize 110 leaded race gas in a stock class car?
Several states have had 10% ethanol mandate for 20+ years, this is nothing new. If there is a concern w/ local fuel quality or octane rating, mix in a couple gallons of race fuel. But also realize there is approx 10% ethanol in Sunoco 100 octane unleaded.
Maybe the better fix would have been to allow adjustable fuel pressure regulators (which could compensate for needed AFR reduction for high ethanol blends above 10%), rather than opening the door for custom chip tuning.
I have not shopped for 3.2 DMEs or stock chips, but the 944 market is saturated w/ stock chips and DME/KLR units. Found readily. And there are various electronics shops that offer Bosch rebuild services for ECUs. The DME EPROM is probably the most durable component of the DME, other than the metal box itself. They don't go bad, unless someone has messed w/ them (plugged them in backwards w/ the power on, bent the pins on them, accidentally set off an EMP device, other?? [EDIT - Dog ate it]).
Anyone w/ a EPROM burner can copy a stock chip. Just find an agreed upon vendor to do so and supply PCA Approved/Certified copies of the stock chips.
This hits the prepared cars pretty hard, and a handful of other cars that are in-part differentiated by engine output based on DME changes (Firehawk/Clubsport 944S2s compared to stock S2s, and 944 Turbo Cup/Escort cars compared to stock Turbo S cars). And with respect to the turbocharged cars, tell me how an aggressive ignition tune will not increase exhaust energy flow thru the turbine and therefore not increase boost pressure?
No point in discussing this one now, too late. But wow, I never thought this rule had a snowball's chance of passing.

I have to say, I didnt see this passing either.... but I will say I'm glad it did.... Stalling with lighweight flywheel is a huge issue in my car, I run all year with a chip and swap the stock one back in at race time... It will be nice to not have to swap them in and out.
Not to mention my dog ate my stock chip this year (true story)... Wasnt sure what i would do next year.

yup.. as long as its steel....
"The dual mass flywheel on a 964, 968, or 993 may be replaced with a single mass, ferrous material (magnetic) flywheel."

95 993's can use a custom chip and the 96 993's can not as they are obdII and do not have removable chips.

Check your ring and pinion, you should not be running out of gear with an 8/31 setup.
QUOTE=Der ABT;9973801]man from the drivers seat i have to disagree, im running the 15s he is running the 16s so its also a bit different there, i had a run several time outta 10 and couldnt gain on him, last year when i beat him (sorry had to say it as it was my first time winning a race overall) i could pull on him up from 5-9...this year i wasnt running that great Steve wilson, dwyane and i were nose to tail last year.
this year dwyane got the correct fueling to the car (old cis wasnt working last year and i think blew his motor from being lean)...i think he will tell you down low his car pulls more than it did last year (we were .1 off lap times with him getting the better lap) this year was .5 or more .....
may not have looked like a big difference but from in the car there were a few time right next to him where if i was in 3rd gear we were even, 2nd 4th and especially 5th gear he pulled slightly...not to mention i tach out on the front straight....so at watkins that euro just WALKS me mainly due to the revs and slightly higher hp up top (my tq should help in slow speed but i think it evens out with the weight)
need to add...
alot of it has to do with the driver...a fully stock version of both cars (i think dwayne and i are good candidates) should be a darn good race with each car having a slight advantage at different points....but with the euro weighing so much less it takes away the tq advantage i would have down low making the euro the car to have....still think the euro will be the car to have (again all things legal like i think most cars are).....driver is the biggest cheater mod one can do...my driving ability today vs 3 yrs ago is STUPID.....i couldnt get below a 127/126 at summit...now im 124 flat....NO changes cept sway adjustments.[/QUOTE]

I was curious about that as well, the first time I saw Evan's video.
I checked my data from Summit and was suprised to find that my top speed was higher than at Road America, Summit's front straight is crazy long.
It seems totally plausible that a Carrera on 15's could get into the limiter.
