Firstly here is my log: http://www.stigmundfreud.f2s.com/Log_0002.efi
secondly I created my pid selection with this thread: http://forum.efilive.com/showthread.php?t=240
thirdly: the Car is a UK Monaro/GTO with an LS1 5.7 block
Fourth here comes the hand holding....
I bought my scanner a few months back from ringram, he and a few here gave me some help getting logs etc but time passed, the tool lay in the boot of the car until today.
I downloaded the new version of the scan software following a PC reinstallation and I am sure I was able to record the injector duty cycles before but no longer can find the PIDs for it. Am I missing something obvious?
Either prepare to laugh/cry at the next bit OR applaud me on getting somethng right, I'll leave judgement for later:
Open Loop/Closed loop
Also could someone take the time to explain open loop/closed loop for me? I have tried to read up on it and it seems to be closed loop when using the MAF/O2 sensors and open loop when using the VE Table? My understanding is the MAF only really works over a given RPM so the car runs open loop until the maf can operate then it closes the loop?
If my understanding of this is correct, looking at my logs you'll see it seems to mostly run closed loop and only sometimes goes to OL-Drive? Sometimes it does this with 0% throttle so on a deceleration, sometimes not. The conditions seem different.
Either my understanding is completely wrong (in which case laugh) or I'm just not getting my basic understanding quite right (in which case cry).
