I have a 02 z28 with a cam, ud pulley, lt's, cai, nothing really crazy but when i took it to a shop to have it tuned they told me it was stuck in open loop they tried my preditor and a hp program they had. it wont log short or long term anyone ever had this problem? Any help would be great!!

 

What does the coolant temp getting to?

 

A bad O2 sensor will prevent C/L.

 

running temps are normal like 200 or somethin.. and it has a cat delete no 02's is their a way around it? or will i need my o2's?

 

put the O2's back in and have it retuned...
Did you tell the shop that was tuning that the sensors were gone?? If so, and they wondered why no CL... Find another tuner...

 

alright cool, thanks alot!!
