Running rich and still crap timing

[Omega]

My new goodies include: SBR-G50, and a FMIC (still using the 190 FP & 550 injectors)

I brought the settings on the AFC up so that it is running really rich and logged a few runs. The timing would fall flat and basicly stay there throughout the run. I finally hooked my WB up and I was running 9-10:1 AFR. I have brought that up to high 10's, but it still doesn't feel like the old 16G did.

I really don't think the 550's stand a chance if I get the tune back to where it needs to be.

Will the ECU screw the timing if the car is running very rich?

If you are running rich, 10.8 A/F, then the 550's are obviously big enough. Lean it out more. It will make a big difference from 10.8ish to 11.5ish to 12.0ish. I noticed a huge difference from the high 10's to the high 11's.

just wondering if how can i adjust my air fuel ratio? thanks for the help!

get an safc or some sort of fuel management to lean it out. or you can get a chip. i've been around 11.2 afr and i had to take my safc to -48 on my highs to get it there so i would go with DSMLINK.

I have had the same prob,i bumped my fp up for now until my 680s come in,but with the 550s,i have them leaned out like 5 percent across board..to4e 57...its crazy..i had it 10 percent rich across the board and the car would feel like a pig,leaned it out alittle and it turned into a monster?!I dont know it must be a dsm thing hahahhah

Well, I ordered some more toys.

The 660's arrived today. I am waiting on the FP and the fuel line upgrade. I am going to hold off on the pump until I am sure I will need it.

The new filter I picked up is TINY! It's about 3.5" long and has the dia a little smaller than a toilet paper tube. I wonder if this filter is for a carb.. not FI?

Who is running an aftermarket filter... and what are the dimensions?

i got the russell 6an fuel filter from jegs and it was 1/2 the size of my factory and works fine so.

Hmm, I think I bought the same one (http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=1485&prmenbr=361)

If you enlarge the image.. I am pretty sure that is the actual size.


-6AN of course.
