Thread: Quirky turbo issues

throw a fuel pressure gauge on there and make sure the pressure is correct.

Fuel pressure is correct, 60 psi with vacuum off. And 50psi with it on. I have a Nismo FPR

Lynch, it would be awesome if he could have it in and out fast, I'd drop my dollar on it to get it here within a week. So I should hit jktuning? Do I have to send a ecu out like JWT or do the send a board that I install, Just wondering because I have like 5 spare ecu's I could send in JWT's stead. Wish there was a sr20forum discount lol

Ill clean my pm box out

Does the sticker on the ECU say it is a 4 bar tune?

Yeah I had it repaired and reflashed for 4 bar

Turn it down to 3 bar and see what your AFR's are.

I can definitely get the ECU turned around in a week since you are pretty close to me .. UPS/Fed Ex should only be 1-2 days for shipment and the ECU will only be in my hands for 1 day.

Zeek, the tuner in my area has nismotronics on the shelf....I think I mentioned it, maybe not. If it hasn't alreay been suggested to turn it down to 3 bar, I know I was thinking to suggest that at some point as well.

I'll be Nismotronic in a weeks time.

Btw oil weights for the summer was thinking 10w-30 but I am running mobile 1 5w-30

Then ill head to marsh if they'll have me.

Did you ever Recirc that BOV?

How are your injectors? When I initially swapped 5 years ago after my build, I had similar issues. Turned out I simply had a torn o-ring on an injector.

Try this for shits and giggles, start her up and pop the hood. Unplug one spark plug wire at a time. If when unplugging any one of the 4 shows no change in idle stability, you've then narrowed the issue to a specific cylinder.
