SignUp Now!tank filled to top and it wasn't that hot out 45 deg tskDoes the holding tank level have any effect?
How about temperature?
If you don't mind what's the combo?interesting that you lost 50psi and afr only dropped .3 those targets look lean to me regardless.losing that kind of psi I would look to get the pump rebuilt.View attachment 317881 I haView attachment 317883 ve an ALKY system and I've been logging my alky pressure for a few months now and on the last 3 times out the psi on the PL are only reading around 90 - 105 lbs at WOT, before when i first hooked up sending unit it read 150 lbs at wot.I don't see any leaks at pump or on line when i push test button, pump was rebuilt at least year ago, maybe time for new rebuild i guess, any more things to check before i send it out thanks.
Did the injector duty cycle jump when you lost alky pressure?and what kind of timing are you running?Here is my set up, I have 5 volts going to julio ‘s alky sending unit, I haven’t checked v at pump yet, when I get his alky pump tester then I can eliminate one thing or replace it , maybe it is sending unit. I also did notice that the af and o2 didn’t change much also with the loss of pressure, we will see tksView attachment 317931
See what the injectors are doing.something seems off.My injector duty cycle I’ll have to check when I get off work later but I believe pretty much stayed the same my timing is at 21.9 in high gear but I also noticed that my IAT still dropped pretty good went to methanol Kicked in so I’m hoping it’s just the sender going to power logger
