I ported throttle body and charger housing,now code P1101, any suggestions on where to put the MAF frequencies? It runs stronger after adding fuel to PE of course but obviously Maf cal is incorrect. If I switch to MAP will this code still appear?Any help would be greatly appreciated, Thanks Tim
Thanks for the input,i should tell you that this is an 07 CobaltSS sc 17psi, no cat, now tbody and scharger inlet ported,charger outlet ported. I'm not sure how to calibrate the MAF, have made changes with increasing and decreasing entire scale and still end up with the code.Any suggestions? Thanks Tim

Maybe calibrate the MAF and see what happens after that, trust me it helps a lot.

He has an lsj or le5 blower swap
Did you make the plate larger cause you might need to change the area scaler.

did you try raising your maf fail high to 16,384 hz under the engine diagnostics section.


to calibrate the maf you need a custom pid watching ltft+stft and your x-axis is the only axis you use and it has the same hz frequency values as the editor shows for the maf curve. then paste special by percent or percent half until satisfied iirc

You might have a maf problem cause that code doesn't have anything to do with going over the fail rate. You have any logs or copy of the tune you are running?

doh!
