Thanks that info is awesome and just what I was looking for. There's only one nistune tuner in the entire state of Texas so most help I get is from the GTRCanada forums. Since there are only about 2 or 3 E85 stations in Canada, there is not much help for tuning for it.
I have z32 mafs, 1000cc injectors, 450/lph fuel pump, tomei FPR, R34 N1 turbos. If I can get a decent e85 base map I can street tune for now until I can get to a dyno with a tuner familiar with nistune.
Once I get it dyno tuned. I'll gladly share my map to help a fellow GTR owner. Not everyone is a D-Bag. Plus I'm in the US, so we've only just been able to get the 1989 R32 since Jan. It's almost impossible finding someone familiar with them.
