Hello everyone,

I have recently purchased a Cobb AP v3 for my 2011 Evo X GSR
My car is completely stock and I have tried using both the v403 LWG and the regular ACN 91 map and I keep getting check engine light.
I haven't noticed any knocks but the check engine light throws me a P1071 and a ECU code all the time.

Anyone know what I should do about it? Thanks

 

Is that supposed to be P0171? If so, that's an indication that the car is running into a lean condition. I'd recommend double checking for possible intake leaks. If you'd like to email a couple of datalogs to support@cobbtuning.com we can certainly evaluate them for you!

No, it's P1071, fuel system too lean Bank 1.
Should I log my car while the CEL is on?
Thanks ahead.

 

I have the same code and it's PO171 (Fuel system lean bank 1)

 

Have you made any changes to the car recently that could have caused an air leak?

Shoot an email with your modification list, map version, and a datalog over to support@cobbtuning.com. We can take a look and see if there is anything obvious.
