I'm converting my ls1 turbo to E85 , ive read many threads and articles on the best way to do it,
if I change the ratio for stoich to 10-1, will all the other tables compensate as they are in lambda?
Then just make PE .7 odd to suit the E85?
Is there any other tables that may be out?
the o/s is 1290003 if that helps
Any idea welcome thanks.
Yes, correct.
PE set to lambda 0.7 implies you're running boost... 0.7 is rich for boost, you can go as lean as 0.76 (if VE and MAF are correct).
Ok so I have got it running on E85 on 10 psi but there is no way it will take anything richer than .80 lambda , making 20rwkw more than 98 with a few extra degrees of timing, but every time I try to richen the mixture it misfires. Is there a chance that the e85 in winter ( from a service station in Melbourne) is not quite e85? It definitely seems to like to make power leaner that it's supposed to be. It normally runs 11.5( .78) afr on 98 with around 12 degrees of timing ( stock ls1 bottom end, mild cam ) . I would have thought it should take being a lot richer on e85 but it doesn't seem to like it .
