Doooo it!

I wasn't sure if maf comp worked like a raw enrichment or not. Sounds like it does and is ahead of fuel trims. I have seen a lot of pte 1000 threads too btw

 

Hem.. Definitely gonna have a look on the lift ASAP .. I run an entire slip fit exhaust soooo

 

Oh jesus slip fit lol.

EDIT: I say this because the WORKS 3" IP has 1 slip fit connection on it. One day, I was rowing through the gears and my car got exponentially louder. I looked and my friend and said "I think something came off or loose!?!" I basically had no axle back and pulled over to inspect. Easy fix, loosened the band clamp, slipped the aft half of the IP back in, and tightened the clamp making note of the slits in the larger OD pipe (they must be covered by the cband potion of the clamp).

Also, I had a full buscher 3" slip fit exhaust a long time ago and had to have it welded minus the rear muffler for ease of fitment due to leaks everywhere over time. Nothing a retighten/retorque/reseat couldn't fix but it was getting annoying as a DD.

 

 

 

I'm gonna relocate my aem to the downpipe . And see

I still idle at 15.7-16.2 and hovers at a 0 stft

Swings between 37.5 and 43 hz

 

whats your base idle set at?

 

900 rpm pretty tame 12* of advance

 

Yes. VE affects trims. The only thing that doesnt change is the trim target AFR is still stoich (14.7)

 

^^this. Mine has been like this since I put a wideband on 5 years ago. Fine at cruise, 16.4ish at idle.

I tuned SD in OL for months last year, ran 14.7 at idle. Then once I turned CL back on, back up to 16.4. Kicked my *** trying to figure it out. But since it always hunts for 14.7 at cruise, I figure its a small leak after the o2 housing that is just big enough to throw off the wideband but the o2 sensor is still good.

 

My fuel trim just keeps maxing out -12.5 I've jumped my scaling to 1008 and same thing . No leaks.. I stuck her back in open loop gonna ve tune some more

 

Dont tune by LTFT which is what it sounds like you are doing. Turn LTFT off and then tune solely off STFT.

 

Ahhh just turn ltft max to 0 in the rom? Edit no such table

That makes a lot of sense especially so you can adjust your maf comp and ve with out fuel trims getting in the way. If that's where you're headed..

How do you disable ltft ?

My stft is right steady around zero but hunts 16's.

 

Any fuel I add via maf tables shows up in my stft as removing an still hunting 16 lol

Do I need to be intuitive and remove the quantity from my maf scale? And stft pulls fuel because its over compensating ?

Edit just took 5 numbers from my maf comp at idle and it idles and stft te same numbers

Dropped my ve from 80 at idle to 68 no change in cl even though that's where 14.7 ish is in ol

How can my stft be at 0 but my idle be 16 ?

 

How do I disable ltft?

What needs to be adjusted if my idle is -+ <1% stft? Yet still 16.4 afr
