Got this message when I had and OBDII scan at O'Reilly this evening. I have a couple of questions about it. Just had my car in the shop for carbon removal and they replaced the injectors as well. I do have an RMW tune but am wondering if this is contributing to the problem? Anyway also wondering if driving it like this will cause a problem? Car seems to be running great but I sure don't like having that CEL. Should I revert back to the stock tune? Any suggestions are appreciated.

I reset my ECU by disconnecting the battery. Still the CEL light came on. Making plans to drop off the car and revert back to the stock tune. Can't help but think that the tune is contributing to my recent problems. Any suggestions or comments are welcome. Thanks!

I dropped my car off at my tuner's garage on Sunday and the diagnosis is that they car is running lean on all cylinders but most notably on cylinder 1. It's ok to drive but they think that it's possible the rmw tune I have got erased when I had another garage clean out carbon buildup and replace the fuel injectors.

They suggested re-applying the tune to see if that remedies it. Unfortunately they are taking customers racing this weekend and aren't available. So I'm going to pick up the car on Friday night and drive it home.

My question is, how difficult is it to re-apply the rmw tune using the dimsport module?
