stock engine - EMS Tune with Race Gas?
will you get any gains tuning a stock engine for race gas?
would it be possible to have a regular 93 map and a racegas map for using a the track?

It will however help the car when you take it to the track and it sees more abuse than normal driving. Race gas has a higher resistance to detonation so as things heat up a bit it will just give some extra safety for the abuse the engine will see.
But it is by no means necessary as I have done a few cars in the 11:1 - 12:1 compression range and they race regularly at the track on pump.

same story with e85 i suppose? less than +20whp and a lot more fuel burned?
You need approx 33% more fuel with E85 compared to gasoline. Essentialy it contains less energy per volume than regular gasoline does.
If you run race gas than you really won't use much more gas than you would just running pump gas.

No. E85 is a completly different type of fuel, it is 85% ethanol and 15% gasoline.

i wasn't clear. i meant aside from requiring increased fuel flow rate, would e85 provide about the same gains?
But yes, it would produce very similar results.

My understanding is that the E85 that is readily available at gas stations is NOT high enough quality to be used as a performance fuel. I think it has to do with the ratio being inconsistant from station to station.

A friend of mine two years ago had an issue that was similar where he was tuned on E75 and didn't know it. Went to another station that was E85 and the car was stupid lean. Switched back to the other station and it was all back to normal.
