The problem is with logging implementation in boost/knock chip. Fuel/ign has a good implementation, no issues there.
Boost/knock needs similar logic of offloading that stuff into non-critical subroutines. Right now it's done in RI_TI interrupt on the fly and that's too expensive, so after 7400 rpm you can have problems.

ECU seems to crash at 7500RPM
been trying to sort this one out. my one car refuses to rev above 7500RPM. when i get to 7500 the logging stops and crashes as well and the car seems to shut off. trying to achieve 8000RPM. has anyone ever seen this before? thinking about disabling the logging output to give the ECU back some of its processor usage to see if that fixes the problem since PRJ did mention that the logging output does put a toll on the processors at high RPM.Tags: None
