Thread: Well how about that? Running lean

Also check the wiring to the pump, i had a car a while ago that no matter how much fuel i screwed into it, it would run lean, checked fuel pump voltage and it was 9volts with engine running. Put a decent relay and wires in and all good, and thats with the original 15yo pump running on a turbo engine.

I'm dead sure about the daughterboard but double check won't hurt

Funny thing I have plenty of tools but a Voltmeter, gonna borrow one from a friend tho

I'm glad I don't need Nistune, just love the simplicity of NDS

I would think the pump is bad as well. Keep us updated.

Haven't done a thing yet since I don't have the neither the blazt or burner for this is one recent datalog where it shows a low duty cycle even up top

Also the injector output is stupidly low

I know is apple VS oranges but my friend's DE peaks 75% duty cycle and 13.4 injector

Changed the gas map, now AFR's are in 13.5 range

Never felt the car this way, is a matter of tune now

The downside is Check Engine Light came instantly when I burned the new chips, don't know why tomorrow I'll just mess with that

Thnx

Looks like my TP scale is off and that's the main reason of not getting proper injection, tomorrow I'm datalogging the scale and keep working on the bin

I'm oficially speaking to myself but I finally got em in the 12.8 AFR range

Still got a couple of spots in midrange where is 13.3 AFR though

Here's my gas map now

13.3 is ok, but try for 13.0

was it the pump?

peace

Fuel pump is ok, only messed with the bin... That TP scale is a btch lol
