7M hit 18psi with stock AFM and still very rich...

[suprafanatic]

no no.. i have it tuned with the SAFC II i can make it leaner. im just saying i tuned it alittle bit leaner from how it was before the safc and it boosted up to 18psi but was still slightly rich. i can tune it even leaner so its around a 12, but im pretty sure it will just boost higher...lol

gees this car is blessed by the car gods man. lol

I should be able to verify he's not reading the WB backwards sarcasm today

Well, that killed this thread.:icon_evil

 

[Quin]

He is in fact not reading his WB backwards. His car also doesn't hold boost, on the dyno he hit 15PSI but it dropped off to 7 pretty fast.

 

[starscream5000]

But a dyno can't load the car up like it can just running on the street. Have you had a chance to see if it holds on the road?

 

[Quin]

It doesn't. He just tested it, hit 17PSI, dropped to 10.

EDIT: He said his AFRs hit 12 this time, which is still richer than my 440s with increased fuel via AFC and AFPR were at 17 PSI

 

[starscream5000]

It's most likely the injectors.

Is the car his DD? He may want to send those puppies off to be flowed/cleaned, so he knows exactly what he's got.

 

[Quin]

Yeah, it's his DD.

I see you're in KY, why weren't you at the Indy meet this weekend?

BBQ festival in Owensboro.
Brother's b-day party/relay for life fundraiser.
Pregnant fiance doesn't like supras.

just would like to say that after safely leaning out my afr's w/ an afc I can still only run 12 psi w/ out gettin into fuel cut.

also would like to add that you would not see 12 psi (without hitting fuel cut) if you did have a boost leak and were using the stock fuel system. I've got a boost leak now and I'm hitting cut at say 4-6 psi.

damn is there anything else in your life that happened that timeframe? :biglaugh:

That must have been an insane time for you:biglaugh:

Yeah this seems to be the norm from what I have seen and heard. However, thats why there must be something that we are missing. I would like to see a flow chart of the injectors as well. But to me it just seems unlikely that it would be them unless the previous owners ran crappy gas. Cause I sent my mk2 injectors out about 2 yrs ago and they have never been cleaned before and after they were done the shop said there wasnt anything wrong with them. So I dont think it could be the injectors. But anythign could happen so I guess go and get the check done you never know soemtimes.

It was actually a fun weekend, stayed plastered a good portion of it .

 

[Quin]

Valid reasons for not attending lol

I'm still super confused about this car, he shouldn't be able to hit 18PSI, he shouldn't be that rich, blah blah blah

 

[GrimJack]

Ya, it's going to be something odd. You'll tear out the injectors and discover they are bigger than stock and find an HKS FCD wired in somewhere - or something like that.

 

[IHI-RHC7]

OOOH, FCD...
But he would've seen that when wiring the S-AFC...
I'd swap out your AFM electrics and see what happens. Also, the stock fpr with a walbro could hike the fuel pressure way up which would account for the rich condition, and the missing screw would account for the hitting 18 psi w/ no fuel cut.

[Quin]

HE might, I'm not walking all the way to Illinois! :biglaugh:

I don't think you can hit 18PSI even if you bored a hole right through the middle of it. I bought my car with a Lex already on it, so I can't say for sure, but his AFM looked puny compared to mine. Dunno about the Walbro + stock FPR, but I do know on my car running 7 PSI over stock FP and dumping fuel in with the AFC I was still leaner than he is now.

 

[drbowser3]

Haven't messed with a stock AFM in a few years, but you claim to have the screw out all the way. I thought the Lex AFM had the screw, not the stock one.

 

[Quin]

His has a screw, don't ask me why lol

I can verify that it has a screw, and that it is NOT a Lexus AFM. I held my Lexus right next to his.

Actually, this might be pertinent. We put my Lex on his car for a minute or two and it ran lean as balls. I figured it was just because the ECU was just starting to learn how to use it. This was at least 500 miles ago, though.
