I am going to datalog my car here soon (its going lean past 4k) can't find the problem.
What is the absolute best parameters to log for this? Volts, FPDC, volt at the pump, MAF? Any other values? I have a wideband so I am not going to log A/F since I know its going to go lean.
Also whats the best way to log this? Do a slow pull to 4500 or 5k or rapid pull? Do I let out right away when it goes lean/buckles? Or hold it for alittle bit to let the SCT record the data (Of course I want to let out right away lol lean is not fun but last time my SCT didnt log it fast enough because I immediately let out). I also already did quiet a few pulls past 4K trying to figure it out and I'm afraid of doing anymore not to blow the car up. Maybe there is something I can do to avoid doing these pulls, like check the pumps first to make sure there working, (I have 3 walbros I know there on since there loud but could be one of them is taking a crap, how to test these?) I already changed the fuel filter.
This might be a stupid question but can you log fuel pressure or anything about injectors? Let's say if the fuel pressure drops can you log it on the SCT x2 handheld?
My setup is:
Triple 255s External
Aeromotive FPR
Bosch 105s
E85
2.9 whipple.
Thanks
