When my 2008 Corvette was new, straight gas was the normal gas. Now, gasohol is the standard everywhere. These require two different values for "stoich" .
Could my C6's computer simply be re- flashed so it correctly calibrates my car's air / fuel ratio ? I notice my NPP exhaust gets coked up.
Thank you . Gary Lovell

Any tuner could do that for the cost of credits. The car is tuned so rich from the factory that it probably won't make any difference though.

The inner pipes on NPP will get black carbon buildup.

Here's some lite reading of AF ratio's & Lambda readings using all types of fuels on the market. There are lots of variables so pinning down one setting for your car maybe fruitless at best.

Interestingly here in Upstate NY the local Stewarts convenience stores have high octane gas with out ethanol. I use it all the time and appreciate vendors that do, better for the vette and other items such as lawnmowers, chainsaws and other outdoor equipment that one stores for lengthy periods.

I have to buy the VP racing fuel by the gallon for my small engine powered equipment which eliminates that longer storage problems with pump fuels.
