so my car has been runnin great so far...just your typical hicups for a 6 port turbo....it still had its rich spots but the other day it got really bad...right beforethe secondary injectors kick on it gets reaslly bad...9:9 to 9:4 at 3K up till the secondaries kick on...then its fine...i dont know why it started this but its a recent NEW problem...the secondaries are fine as far as richness and it only starts at 3K RPM's...i have my safc turned to -40 right now at 3K and still get get it any leaner....i even changed the NE point on the SAFC...it was 3,600 i think and now i have it at 3200 and its still bloody rich...what is going on????
it just started getting really nice out if that matters??? from 40-50 ish to 60-70 ish...

 

I'd check the AFM
Clip an ohmmeter on the AFM & work the flap.
The resistance values should start around 150-200, the go up in steps to around 550-600 ohms as the door opens, then near the full open end of the stroke, it may drop back to 400.
It seems weird that the sweep is non-linear, but the 3 working AFM's I tested all did that.

 

thanks..it is a tII AFM on a n/a harness....im using tII AFM and boost sensor with the rtek...should i try another AFM as well???

 

ok...going by this photo i got:
E2 --Vs
275--- 550-680 ish it wouldnt stay still

E2---Vref
it was 280 and when i opened the flap it did nothing...
is my AFM meter shot???

 

i did the same test to another AFM that IS a N/A AFM and its the same xact reading about...apparentley ive been running a n/a AFM now and not knowing it...and i must be doing the test wrong since the second test does nothin...WHAT am i doing wrong??? what would cause my problem??

and their are 2 E2's...im guessing i use the left one to test???

 

To begin, I really wouldn't go yanking -40% out of your fuel map especially under load. Did the power change at all when this happened? Does it hiccup/do anything strange at that time?

 

no power change...hesitation though because its so rich(9:8 via wideband)...i did turn it back up (safc)..i was just seeing how far it would go....

 

changed the AFM with another and still same problem...im at a loss here on ideas...anyone know whats going on???

 

c'mon...what is the deal????
im stumped on this and been searching forever...
please help....

 

Get a standalone? What do you expect us to do for you? It's not all that difficult, start with the normal crap (check every sensor, replace plugs, clean your injectors, etc).

 

thats the thing...all the normal things have been replaced..plugs, wires, filters and such....
i dont know what sensores i should start checking?
standalone is in the future...someday

 

The only time I have ran into this is with the following items.

AFM
Injectors
Injector wiring.

 

thanks... i ill check into the injectors
i just didnt think it would be the injectors since they were cleaned at the time i put this project together last summer...so they have about 1,500 miles on them...ill still check them though...
