Hi, I have a problem with ecu and I cant seem to find the fault. Car runs fine and with no issues part throttle.
When I open throttle 100% it starts to act weird. it feels like ecu protection is kicking in but checking the logs (ill add a file here) ecu prot isn't doing anything. Its jumping to 17afr for like 300ms and then going back to normal. VE table is smooth and plenty of fuel. walbro 255lph pump with 875cc injectors on m52b25 engine. I think this ecu is broken or some sensor is about to die.
Ill add the whole tune file also, maybe somebody can spot the problem
It seems that the injector duty cycle jumps to 0 at random moments. How can it be ?
thank you.
