timing advanced out of no where

[Javi802]

So i installed a different turbo on my stock sr two days ago and got it running and what not.

Hooked my computer up to the consult plug and used nissan data scan to see what it was doing.

Everything seemed fine, besides a knock sensor code. Timing at idle was at 15btdc


Two days later though and now I'm idling at 20btdc.


Anybody have any advice as to what my problem may be?

I would search more, but i don't know exactly what questions i need to be searching for

Still idles at the same rpms as well

Use an actual timing gun to check. Otherwise I'd check if somehow the CAS became loose.

Well i just went back out and hooked the computer up again and now its idling at 15 again. Hmm


Im still gonna hook my timing light up and see if it's indeed at 15btdc

Check your TPS voltage. Should be less that 0.48V with throttle closed. The ECU uses a different timing table when the throttle is closed.
