Someone in San Jose to help tune?

Hello all,

I'm looking for someone in or near San Jose to help me tune my EMB. It's running nice now with a map from olderguy. Is there anyone out there that can help me tune?

Send me the current .gsc file along with a datalog of a spirited run(both files) and I'll see if there is anything further I can do from here.

OK. I'll try to have the logs to you today or tomorrow.

Just an update:

At about 3500 rpm under moderate (not hard) acceleration, the is a very defined hop. I'm sure that it has to do with the boost now in the system (I just added a manual boost controller that brought the boost from ~2-3 psi to ~6-7 psi). I have the feeling that there is a fuel change in the table at that point that is causing the "pop".

Hopefully the logs will show something.

Tony, at 3500 rpm, you should consider checking the clamp voltage. It sounds like a tip-in issue potentially, where the car is boosting down low... but the ECU is pulling stuff out.

Also, I found that if I removed the 49% TPS tuning row, it helped a lot with the transition stuff around 0 vac....
