Default N75 Questions (ASP Stage 2+ Chip)

N75 Questions (ASP Stage 2+ Chip)

I have a stage 2 ASP chip (without DP's nor Exhaust) and am running really low boost...almost stock figures, like the chip was never installed. I completed a pressure test, checked the 710's, new primary o2 sensors(bank 1 and 2) and VAG (everything seems normal)...now I'm thinking the N75 is the weak link...

Even though I don't have the other pieces to the puzzle installed (dp's, exhaust), shouldn't I see some gains even though these items are not installed (true/false).

Thanks!


Thanks!

I put out 15-16psi (hold) and 18+ (spike) on my ASP code. Something doesn't sound right on yours...

Would the N75 limit my boost? I've read when the N75 fail or is about to fail there are high spikes rather than low boost

Default Have you called Mark or Frank? You may also want to unplug the ECU for a few minutes and see if...

if that helps. I know that it sounds crazy, but give it a try.

Default you should definetly do some logs

You should also log your car with another chipped ECU.

My software was having issues, and I sent the logs to ASP. They were able to re-write some code for me and fix the problem.

Default Hey brian, let's schedule something...

I can reburn the Stage2+ file for you. Who knows what might have happened. I think Jordan logged the car though right?

Sounds good! Jordan logged it correctly, I just think something else is going on with the car...maybe it will all go away when the DP's and exhaust are installed

Thanks

Brian
