When i talked to fore innovations he reminded me fuel peak demand is actually at peak torque which is where im seeing the worst afr but if im truly running out of fuel i need bigger rails?? I cant imagine these 2 pumps cant handle the little paxton with a wastegate.
Unfortunately no I went with the sct X4 and am regretting it now. Doing it the country way, strap a fuel pressure gauge to front window for a quick 3rd gear hit now.
Datalog attached with the video above confirms I have fuel pressure at the regulator. Im confused now but will be emailing all of this to lund in the morning. Something weird, maybe im pushing more boost than I thought...
Redneck engineering at it's finest. Pressure did exactly what it's supposed to do.
Dont you have the ATI balancer? I'd measure it to ensure you have the stock diameter. Still haven't looked at the logs, I'll be off tomorrow tski g care of a sick kid so I should have some time. Keep working at it, we will figure it out!!
I am no tuner and far from a pro at this but after looking at your datalogs I think you have a o2 issue on Bank 2. Bank 1 and Bank 2 should mirror each other, on the last datalog you posted it looks like your Bank 2 wasnt even reading. On the other log it was reading but your Bank 2 short terms were the ones spiking.
I am not sure how you are reviewing your logs, pull them up using Livelink and you will see what I mean, its hard to see it in the Excel format. From my limited experience I think your Bank 2 o2 needs to be replaced
**Edit, next time you do a log can you add Lambse Bank 1 and Bank 2. This will show commanded air fuel and then we can compare it to measured afr**
