Can anyone tell me why I switch between commanding 14.7 afr and commanding 10.1 afr at idle. My pe is set to 11.7, but I'm getting no where near the right kpa to enter pe.

 

Probably another parameter is set wrong and you are in PE at idle. Kinda hard to tell....post up tour tune.

 

This thread will explain a little better. The tune I'm running is on this thread.

ur question doesnt make sense..

 

The problem is I'm commanding the wrong AFR.

 

Sounds like your still running in open loop.

 

What would cause me to run in open loop?

 

so swtich ur commanded afr

 

We can't help if you don't send the file. I sent you a PM with my email.

 

email sent

 

piston protection, I believe. If you start to run lean and hot, you will go to commanding stupid rich for about 30-90 seconds or so and it will go back to commanding 14.7.

 

What should my piston protection be set at? Under my pe tab its set ay 8000rpm

 

well thats not the question..the question is what is causing it to come on to protect ur pistons...u dont wanna disable it and then blow something

 

I dunno, looking at your log you were at 14.7:1 except when you first started your car.......what is up with your stft's??? like 30+ % most of the way through.....

 

It keeps going into OL and sometimes OL-fault what would cause this? Also I had P0433 evap purge solenoid valve 1 control CKT go off once, but it hasen't gone off since and it's still acting up.

 

well, when it goes into open loop what are you doing? idleing?? WOT???

 

Idle or low rpm

Also I'm getting P0135

 

well, p0135 is for your bank 1 sensor 1 o2 seonsor.....if you're having a problem with that, that could cause your problem with going into open loop I would think.

Also, why do you have the fail in your MAF set at 11100??

 

isn't that the limit of our MAF, or am I mistaken?


Problem solved, front o2 sensor, thanks for your input guys

 

Yes that's your limit.

Glad to see you solved it.
