So last week I noticed that the car I've been working on for almost half a year, has a very distinct problem.
After a huge hustle, trying to get my car to start, because my ecu randomly died and the only viable option being a manual switch to ground the MFI relay to get everything to kind of work again, I checked for CEL codes and see there: code 31 for knock sensors in a US N/T.
After a quick research I learned that my ecu might be from an EU N/T model because apparently they came with a knock sensor. I am from Germany, the car is an import.
My questions are now:
Could this be the reason for high emissions and idle? Two weeks ago, I failed the emissions test and my idle is at around 1500. I read something about a limp mode, but I'm not sure if manual transmission models had it.
Is there a way to trick the ecu into thinking that there is a knock sensor without having to buy one.
