I am not very knowledgeable on issues relating to flex fuel and flex fuel kits, but from what I have read I agree with @FlexRex . It is possible the Flex kit was installed improperly, but I think the tuner would have seen this right away as the sensors would not register. I looked at a few WRX forums and kits improperly installed, the tuner sent them away. I think the only way to really get to the bottom of what happened is to someone knowledgeable seeing the logs when he was having issues and logs from when the failure happened. An Engine teardown would also be helpful, but I think the OP has a lot on his hands getting his car back up and runningI don’t understand what can be installed wrong with the prl flex kit yet you get eca% read for the tuner to tune it and not notice an issue.
Could you be more specific as to what it was that was installed incorrectly? Or what the issue was that caused your trims to be all over (moving eca%)?
Id blame your intake (incorrect scaling) for the bad trims over the flex kit being “incorrectly installed” but we dont have enough info really. Do you have an older log of these bad trims showing eca% as well as other parameters obviously?
