SAFCII and 550CC injector tuning problems.

[SFrymyah]

I tried posted in the Tuning section, but got shot down.

I've been trying to tune this thing for two days now and i'm finally starting to get really pissed off because nothing is coming out logical now.

I realized today that i set my Lo settings incorrectly. I set my them according to what the STFT was reading and didnt think to take LTFT into account. I realized it late last night and went out today to make the proper adjustments and try to start over.

My LTFT was at 3.6 and the STFT was around 7 when i started making my adjustments. When i finally got the STFT as close to -3 as possible, the SAFC was reading +7. I was making these adjustments at the 1000 RPM NePoint.

Any idea what the hell is going on?

If its any help, I'm on a T-28 attached to an Evo 3 Manifold and 3inch TBE. Its getting fed through a Rewired Walbro 255 going through an AFPR set at 44 psi. Delta 272's are pushing the valves open

Just a reminder that lo throttle adjustments don't have to be dead on, that's what the fuel trims are for - to take care of any discrepencies. Just a word so you don't kill yourself over trying to get the perfect lo-throttle settings. WOT is a little bit of a different story.....

I've read all of the tuning threads in and out. I'm looking for justification as to why i'm having to add fuel at idle with a larger injector

I'm not so much worried about getting them perfect. Like i said in my last post, i'm trying to make sense of why its doing the exact opposite of what its supposed to be doing
