power enrichment table is per RPM. I am commanding a lean 12.12 due to the meth. I am loooking to see a 11.7 to 11.8ish here, NOT 12.5!!!!! Why only in first gear am I battling to get this afr in line. if I richen the pe vs rpm in this area the higher gears will go real rich, obviously so. Why is 1/2 shift (or really first gear) such a bastard? I have my meth on at 3.5#'s of boost right now. I have the rpm switch on all times. So at this spot (12.5:1) my meth indicator lights are on, so pump is working, meth is flowing (supposedly). It fattens up after the shift. Hope you can see this pic.

 

What is your PE enrichment rate set at?

 

Can I get a bigger pic? Also is this the tune you are using? dewmanshu 2006-05-31.hpt

 

yes on the file.

rate is 4.0

 

I just notice my timing dips off right around the same time the afr comes back to norm. At 1.04 g/cyl I am commanding 20*. At 1.12 I am commanding 19*.

Hmmm.

also, my injector (ms) is 1ms different between being 12.5afr and 11.8afr. That seems to be a big difference as well.

@ 12.5 AFR (1st gear) and 5898rpm the injector ms is 16.7 and 17.0. Dyn air is 1.04 g/cyl and maf is 11291hertz.
@ 11.7 AFR (2nd gear) and 5873rpm the injector ms is 17.7 and 18.0. Dyn air is 1.12 g/cyl and maf is 11611hertz.

 

Check out you dynamic cylinder air pid. It goes up as your a/f ratio goes down.
At 5898 RPM Dyn reads 1.04 @ 12.5:1 in first
At 5912 RPM Dyn reads 1.12 @ 11.7:1 in sec
At 5000 RPM Dyn reads 1.16 @ 11.59: in third
Don't know if this has anything to do with your problem, but maybe a cell or two that is off in the MAF table that only gets hit in first?????

 

well that's where everything points to...is the MAF. But it's a curve and the difference between the gears is minimal (speaking of hertz, like only a few hundred hertz).

As i edited my last post, my injector ms opens more, hence more fuel, so it certainly seems that dyn air of 1.04 is where my problem is and more than likely in that part of the maf.

I am gonna try and squeeze some fuel out of that area of the maf, hoepfully not flatlining that area in the maf.

 

MAF are evil, you know you want to destroy it

See what happened to mine when it pissed me off for the last time... The Dremel...

 

LOL,

I didn't even notice the injector msec, Strange how touchy this things are between gears???
Get the 2 bar O.S and tune away!!!!


















Then you can teach me how, lol

 

LOL...I have the radix so my iat sensor isn't in there, so as Widle already says, as soon as I get off my *** and install the 2bar map, that map is going on the shelf!
