WOT MAF Tune - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hi every one,

I was trying to tune my MAF @ WOT but the MAF signal did not exceed 8700 Hz. in the first pull, is that normal? or where did I screw up?

Your help is highly appreciated.

Thanks,

Post your tune and log files.

If you have premium fuel you should see low to mid 20's timing with little to no knock.

Tons of knock, kPa of only 90, WOT AFR 13.5 when you are commanding a way too rich 11.71, I think you need to step back and do some more reading before you hurt your engine.

He's in good hands. I am guiding him through the whole process and gave him a config file which will help him get it all straightened out. The barometric pressure where he is located is not very high... only 93kPa. 90kPa for manifold pressure sounds about right for a stock cam and intake manifold.

Do you understand how to adjust the MAF now? I can help you create a custom PID that will give you an error value for WOT fueling. It makes dialing in the MAF curve pretty quick.

Yes, today I will take my car for about 10 minutes drive and log the LTFT then I will adjust the MAF by 50% of the value.

Please send me that custom PID, it will really help me with my WOT tune.

Thanks a Million.

Find the PID identifier for your wideband, and I'll type it out for you. It should be something like [AUX.20121] or [USER.9003] or something. I'm not sure where you have your's set up.
