ignition timing with forced induction
I have this homemade turbo kit on my GFs car and my timing does all the way down to 13.5 at WOT at 6lbs , there isnt any audible detonation and im running water injection . the AFRs are between 11.5-12.2 , but its making me mad that the car is pulling all this timing on its own .
what are you guys/gals timing running at ?

"For tuning purposes an for the people who want to see how much Ignition Timing the Stock ECU advances, here u go."
Ignition Timing Advancement at Idle:
At 2007 RPM:
At 3167 RPM:
Hope that clears some issues with tuning for u guys. When guessing how much timing is advanced with 87 octane and with the stock ECU.
Sorry all the pictures are blurry, but my camera tends bother some times.

I was doing a CarPC project with my older xbox, but messed it up in the proccess, also using Linux was a pain in the @$$. The pics are from a laptop. Also I have a new 160F thermostat, that's why the temps are so low. Normally they would be on the 210F range. I live in PR.

hey Eric , are u able to add timing with the harness u have ? I would think 18 degrees would still be safe with good fuel and 50/50 water meth . the car killing the timing is ____ing me off . because there really isnt much difference between 4lbs and 6lbs with it killing 3 points of timing between the two .
I know there have to be others logging what there F/I car is doing under WOT

Yes, I can add timing with emanage. I'm waiting to get the black-box installed before I go back to stock timing (or start to add some). I was looking at some old logs and with no timing reduction the ECU was running like 17 degrees under partial-throttle acceleration, I'm pulling about 3 degrees at part-throttle boost my 13-14 number seems to be consistent.
My ECU is running timing in the low teens at WOT when under load just like your car is.

hey Eric , have u ran the car on a "learned" ecu and then a fresh reset ecu to see if the timing may be different ? I may have to try this to see if I can get some more timing before I bring this thing to the track .
