I was doing a bit of data logging last night. Before going to club night I reset all that the car learned. Had my data logger plugged in to capture everything it learns. Like the knock sensors can retard timing, but it remembers that and retarded the timing and globally effects all future cells until next filed up with fuel. As I'm still dialling in the fuel across many cells, it may have been due to a lean condition.
Gave it some beans as I knew I was capturing it on the data logger. It certainly held back. I was looking forward to getting up this morning and interrogating that log. Well all the logs from last night.
Thought I clicked on the 'Read all button', but accidently clicked on 'Write config' which happens to erase everything I captured. Most annoyed. Need to do that all again now.
My fuel pressure should be 58psi. Its around 64psi on idle and goes down to around 56psi on load. The fuel pressure regulator is in the tank. Easy enough to change, it still the original. It may be best to relocate the fuel pressure regulator to the fuel rails and run a return line back to the tank. Or work with the fuel pressure regulator I have if it is consistently running at 56psi under load I can tune that in, no good if it wanders around though. I have the fuel pressure sensor wired up to the datalogger too, so it will be good to see what its up to.
Not sure why the car held back, the timing hasn't changed, altohugh colder air it does all 1.5degrees of timing. When I say it held back, it didn't feel like it was pulling my teeth out, it was still going well though. Just would have been nice to see the datalog of that.
