gas and tuning

simwahWRX · 02-09-2004, 08:50 AM

Is the oxygenated 'winter blend' fuel I buy here in Michigan going to have an impact on any ECU tuning I have done now, or is there a benefit to waiting until the warmer weather? What about vice versa?

Some say it will have an effect and its not as detonation resistent as "normal" gas. Best way is to find out by tuning on crap gas and knowing that it will work on good gas rather than tuning on good gas then det-ing in the winter.
