Has anyone on here ran an ethanol blend I.E. E35-E40? I am planning to take the car to the track (PBIR) sometime this week so I am looking for some feedback. Current mods are ROW boxes, Green filter, 2nd cat delete and a tune. Going to mount a set of D/R fingers cross I nail a 11.99999!

Not with out a flex fuel kit. You can run e85 if you get eurocharged flex fuel kit. Otherwise fill up with race gas instead.

Even with the ecu being close loop?

OE Tuning has always offered a 50/50 E85/premium pump gas blend, Race gas tune (no higher than 50% blend of E85). This is a specific race gas type tune only to be run with this fuel blend. Many members on this forum have this calibration, 7300rpm limit non-p31, 7500rpm limit p31, black series and 507.

I have recently installed a Flex Fuel Kit from Eurocharged and I have your tune. I have a headers file and a race gas file. Can I use the race gas file with the E85?

I spoke with Eurocharged about this a while back and that would NOT be a good idea. You run the risk of a very lean condition and see through pistons.

From what i've read so far the stock injectors are enough for E30, if i have enough time ill do my own test and throw the car on the dyno just to check the AFR.

I assume you're looking for ethanol to increase the octane rating of the fuel. Is your tune meant for a higher octane, if not higher ethanol concentrations will do nothing for you.

I tried ethanol for the first time a few weeks back.
It was a very conservative mix, I used a 10% eth mixture.

My car has a tune, ROW airboxes, secondary cat delete, resonator delete, and muffler delete.

I definitely felt a difference with eth. It wasn't a massive difference, but definitely felt that the car pulled better.

Is your regular gasoline unblended (ethanol free)?

In the states, the 93/91 unleaded already had 10-15% ethanol mixed with it.

He is from South Africa. Our fuels have a low ethanol content
