hi
I have a ecu jumper harness on the way for my 98 ek and i am running an obd2 p75 and will be running a obd 1 p75. my question is has anyone noticed there car ran better with an obd 1 ecu instead of obd 2 or the same just able to chip it. also what chips would you guys recomnd for a ls swap with bolt ons??? will be going turbo but I am looking for a good n/a chip for now.
thanks in advance.

 

just stick with a stock LS program for now until you can get it tuned. those aftermarket chips are garbage.

 

your car will run alot better with obd1, you don't have all the emissions garbage
