Okay Guru's I'm about to blow your mind! Look at my S-AFC settings!
I didn't even pay much attention at the dyno shop what I was doing ... but I went out just now to write down my S-AFC settings incase I loose them some how ... these are my after dyno settings!
Link to my Dyno charts; https://www.rx7club.com/forum/showth...hreadid=132499 As some of you may know .. I could not boost past 9.59 PSI for some reason .. I suspect a leak somwhere. read my last 2 posts in the above link. I think this almost proves a boost leak must exsist, 720CC primary injectors 1000CC secondary injectors S-AFC high throttle numbers to achive the above listed A/F ratio.. with a rewired Walboro 255/LH 1000 -6 2000 -8 3000 +4 3500 +14 4000 +9 5000 +3 6000 +9 7000 on +16 I think my turbo is making boost at way lower RPM's than the dyno shows and that I am loosing it ... that is a SICK amount of fuel .. chime in plz, Robert. |
that is way not right.... you should be at like -40 or something lOL... at 10 psi. I'm at -13% with stock injectors!
|
I didn't see the A/F ratios on the scanned charts
But your sure you are not running so rich you are killing boost? :-) |
Yeah.. those numbers seem way off. We have pretty similiar mods except for the turbo, I am running stock as of these settings (1 more week 60-1 and haltech) woohoo.
Pushing 13psi on the stocker with a walbro and 4x720's after 4k all I did was remove fuel. I have a WBO2 on the car all the time, so i know what the A/F ratio is, it is in the 10's. here are my settings. Low Throttle 20% High Throttle 60% HI LO 1k 0 1k -5 2k +2 2K +5 3K +2 3k +5 4k +1 4k +5 5K -8 5k +2 6K -14 6k +2 7K -20 7K +2 8K -14 8K +2 |
I was thinking maybe I need a fuel pressure regulator or somthing, I'm not sure what to think. But I really think somthing is wrong :(
|
man thats really odd and it doesnt seem to be rich on the graph but yet still +14 and +16 with those injectors ?? strange
|
are you sure that you have all your injectors firing or some shit? that seems way the ass too rich. But, numbers dont lie
|
RPeck. maybe your airflow meter is messed up??? At maximum boost, I have seen as much as 80% on the safc's airflow value. What do you see??? My friend only sees 65%. Maybe your afm is malfunctioning???

Maybe your afm is malfunctioning??? But I am at a bit of a loss as to whats up now... It could be alot of things :( and maybe the AFM .. I am going to do some major trouble shooting this weekend .. if anyone else has Ideas of things I should chekc out ..by all means post them. I gotta cure what ails my car ... But I somehow think the problems are one in the same .. Low max boost .... boost only way high in the RPM band ... and the S-AFC settings being so off the wall .. I think they are all related to the same issue .. whatever that issue may be is the question. |
Rpeck.
Your O2 sensor might be the prob...most likely it is. Have you upgraded it to a 3wire (heated)? |

hey saabguy, what year is yours? my 88s AFM maxes out at like 64% is this normal or maybe i need to make trip to junk yard?
|
My 87 afm has gone up to 80% at times. My safc settings are quite negative. My ECU is the N332 if that makes any difference.
I slapped my full intake and the afm shot up to 84% in first gear. I took the intake off cause that made the car hit 10psi. My compressor is slightly upgraded so maybe that makes the readings slightly higher as well, but I am only running 6psi, not a crazy upgraded comp. |
You really need to look for boost leaks and make sure your boost gauge is telling you the real story. I can't empasize those two points enough!

are you refering to me?? cause my car is running perfect.
|
Yeah, that's way too much fuel in the midrange.  Most FC's I've seen like to have fuel removed in the 4kRPM range.
How did you come to those settings?  The wide-band said so? -Ted |
