Well its that time of year and I need to get my Evo inspected . I have NO CAT. on the car but the mechanic said he will pass me so long the OBD doesnt read any codes. I normally have a Check Engine Light after 50miles, but it can be cleared temporarily by unplugging the battery. If i reset the ECU can the OBD Scanner still read any codes? Thanks in Advance

 

dont u have a cel fix?

 

no, I normally just unplug the battery.

 

thats a waste of time. who makes ur cat delete? perrin makes a easy-2-install cel fix. works great.

 

My downpipe is made by RS-R. All im asking is can the OBD scanner tell i have no cat if i reset the ecu?

 

Yes.

 

get the CEL fix and youll be fine

 

I put that perrin in.. and im still throwing codes.. says the sencors are not ready to be tested.. grrrr...

 

Well i went to get inspected and i failed, i unplugged the batt. and i got sensors are not ready to be tested. oh well i guess i have to put the cat back on.
