hey guys i've posted a couple of times yesterday. Having troubles with the burb.
02 5.3L 4wd
02 ls-6 cylinder heads
02ls-6 camshaft
Magnuson Radix w/ 3.25" pulley
Corsa exhaust.
Ls1-edit

The teuck has sat for three weeks w/ the batt. disconnected. I reconnected and the truck would idle. reloaded the program and restarted and idled fine. drove it around and got a P0175 and p0175 rich bank one and two. I've got the Radix so I've got bigger injectors My IFR is @ 4.8 and I'm pullin -10.9% at idle and 9-9.5 ish @cruise. if rescale the injector flow would I go 5% larger or 5% smaller would I go to 4.56 or 5.04 to get to -5% ltfts.

 

those cruise numbers are negative too right? i dont think an ltrim of -10% will cause a light.

to get your ltrims to go more positive you need to increase the injector flow number.

 

That's exactly right. Increasing IFR from the actual injector flow makes the PCM think that the injectors flow more than they do which will decrease the amount of fuel and lean it out. Decreasing the IFR from the actual injector flow rate the PCM will increase injector pulse too adding more fuel richening it up.

 

I had an SES light from a -25% LTrim when I forgot to tighten my clamp on my FIPK down. If that is relevant or not, I dunno.

I'd assume IFR is injector flow rate and increasing that decreases pulse width...bigger injectors need less duty cycles as they flow more with less time being open.
