I am trying to figure out why my car is only advancing timing like 5 6 degrees from 6k-7.5k. The car has 27k miles with mods in singature, the car has no misfires, it doesn't break up. I have pulled the plugs but they look ok, should I change the plugs? Even though the car doesn't misfire or break up, can the spark plugs be the issue?

 

Whats the temperature like out there? Do you think the MAF is reading correctly? How do you know exactly what the timing is advancing? What tool are you using?

 

When we log the car, 4ws has the timing set to advance I think around 14 15 but the ecu is only advancing it 5 or 6 degrees. The temps are high 80s

Are you logging knock sum?

Also with ECU+ you can set it to take out ignition at a certain knock volts. Make sure this is zeroed out to make sure that isn't doing it.

 

yes, the knock count is 0. I am trying to figure out if it is the spark plugs that is limiting the timing to 5 degrees, by replacing the spark plugs I am thinking it will fix this issue and allow to run normal set timing.

come on, no one has any suggestions????
