can any one give me a quick break down of what my aem wide band should be showing at idle-wot. below is kind of what im getting.

idle - 13
cruising- 14-15
wot -12.5-13.5 this is what im most concerned about

I also notice that if I am cruising and suddenly give it more throttle the ratio goes full lean for a second before dropping back down to around 13

my basic set up

13b
street port
single turbo
Greddy e-manage boost controller
v-mount
excessive lim
full 3in strait pipe
Power fc
91 tune
1000/2000cc injectors
dual walbro 255's
-6 fuel line from tank to rail
factory omp and running premix

I also recently talked with rob at pineapple racing recently when ordering a idler kit. I was talking to him about premix and mentioned the car made 425whp at 14lbs. he was very concerned stating my car should not be making that much power on 91 with my set up? is there something I should be concerned about here? or do these numbers not seam reasonable?


I searched and found the info listed below but it was in regards to stock turbo on a 2nd gen.


Stock turbo?

13.5 at idle.

14.5 or so under light load out of closed loop.

Closed loop to 15.0 or there abouts.

Under moderate throttle, 13.5 out of boost.

At 0", go down to 12.5 and hold that number until about 4-5 PSI. Then go down to 12 until about 7-8 PSI. Now taper down to 11.5 to 10 PSI an run 11 exactly after that. Once you hit the 15 PSI area, 10.5.

Of course, without knowing how the car is configured, it's all a guess. And timing is rather important...



I know there are multiple questions here but thanks in advance for any and all help. I just want to make sure I don't do anything to harm the motor. its taken me years to get the car to this point.

 

Have you played with the acell advance?
And the sensitivity ?

 

no I have not. I wouldn't even know where to start. I had the tuner take care of everything.

on another not I just got back from taking the car to lunch and all the air fuel numbers seemed to be more in line with what they should be.

12-12.2 idle
14.8 cruising
13.6 no boost but accelerating
right when I got into boost it dropped down to 12 and ended up at 10.5 at 14lbs.

 

At the moment
My afr is
12.0afr and idle is at 1400rpm 2200cc primry
Croose 13.6
0bar 12.5
At 1.3bar at 11.2 ( this will drop down once i get a chance to roaling road it again left it like this as plan to run more boost )
Also what turbo do you have

 

15 is already officially lean. And I think you should go richer at WOT too like 11-12 to be on the safer side especially if it's single turbo.

This sounds like acceleration fuel enrichment hasn't been tuned properly - by this, in human words you tell the ECU that if the throttle position (or MAP depending on how you setup your ECU) instantly changes by e.g. 40% add e.g. 3.70ms more injection.

Usually this is done at the very end after everything has been tuned. Practically you can tweak this yourself too on the road (needless to say in a safe place).
