01 cavalier 2.4 turbo KR problem

[Charger]

I get 6* KR and this is basically the gm s/c reflash tune. I know they pull a lot of timing so I'm wondering why I get that much KR.

I don't have the WB plugged on this scan but I'll scan with WB AFR soon and post it...

Thanks for your help.

Try these settings, copy this HO PE spark table to the LO PE table. I assume your intercooled.
I highly recommend a 160*F thermostat & lower the cooling fan temp.

Yes i'm intercooled.

I already lowered the fan temp to 210*F. Should I drop it more? I will buy that 160* thermostat. Thanks!

I tried the settings and did a scan and got 6* KR again.

Thanks for your help Russ.

You didn't change the HO PE spark table!

I copied the HO PE spark table you sent me in the picture to my LO PE spark table.

Do I copy the same thing to my HO PE spark table?

Thanks!

Yes

Made the change. Still seeing 6* KR. I thought maybe my injectors are too small (310cc) but my AFR are good. I can't log the injectors duty cycle in the scanner, the PID don't work and I don't know why. Can it be the injectors??

You need to lower your ECT, as it never gets below 200*F! What is your wot AFR, as going by the stock O2, you might be too rich.
