Computer program for Cats
Years ago I had MADTUNER reprogram my computer did a great job. He programed the catalytic converters out. Now i want to update the exhaust and put high flow catalytic converters in. The question i how do I program the computer for the cats?

Re: Computer program for Cats
Only if you want the PCM to run the diagnostics for cat converter performance, which restores the ability of the PCM to set codes for cat performance. That is what he "programmed out". The minor change in exhaust system back pressure from the high flow cats will result in small changes to air flow into the engine, but the MAF sensor picks that up.

Re: Computer program for Cats
So once I install the new exhaust system and plug in all the sensors will it be good to go. Or will I still have to adjust the program?
