Pull the power wire to the computer for awhile, and then plug it back in and warm the engine up. Once the engine warms up and hit closed loop, watch the BLM's. If there is any old memory in there left from another set of mods or adjustments, you'll be battling with those BLM's and wont be able to figure out why. I noticed that on mine, I couldnt just switch back and forth between 3" or 3.5" settings on the translator and expect the computer to adjust. Erase the memory, change the translator setting, and then warm it up and drive a little bit and watch what happens. I have a 3.5" MAF, but I have to have the setting at 3". And switching to a different MAF setting without erasing the memory first didnt work. My BLMs were way off no matter what setting it was on if I didnt erase it first. The computer needs a blank slate to work with every time you make a change anywhere, if you want it right. Some may say this is wrong, but its what had to be done on my car to work.
