A few weeks ago I had my turbo installed. For the last few years was running un catted UEL headers and the stage 2 OFT tune. Using the base tune for my kit until my ecutek arrives. I’ve had no codes for the first month of FI. This morning p0240 popped up.

I was told I could use tactrix(my base tune is running off it) to clear the code. The Instructions above about RomRaider are pretty much the same? Or would i be looking at different paths and values.

Sorry I’m not to experienced with tuning but I’m trying to learn.

My tuner told me I would be able to do this in tactrix but I can’t find any sort of step by step instructions.

Thank you in advance.
