maf tuning crap.....

[Area47]

ding. out ran the ve. fuel dump.

question answered!

thank you so much kind sir

[Area47]

now this question being posed.

how in the hell am i running out of ve, when 2.5 cars don't have this problem?!?!?!

[my_bd]

waddya mean by "running out of ve"??

[my_bd]

my attention was drawn to all these pw blips you're getting while accelerating, it ought to be a nice smooth line....

now im not sure. i was going back through my old logs. and it has not done anything like this until here recently. i have a log from two weeks ago, and it doesn't show up. it has only started to happen here recently.

now im really stumped.

nothing has changed since then, other than the fuel map. i have switched back and forth and have gotten the same results with either fuel map.

[Area47]

ya know what. going in the way back machine. every single 60lb log i have has done this. no matter what the maf settings are. no matter what the pe is set at.

ok, so i narrowed it down to possibly two things. injectors, or the map itself

[my_bd]

think man! think!!

sorta looks like a tiny fuel surge or miscalc happenin along the way...

[Area47]

i have been racking my brain with this crap for the past week. this is the only two things i can think of. im leaning more towards the map itself. i honestly can't think of anything else that it would/could be. im changing fuel maps sometime this week to narrow it down.

your map sensor doesn't effect fueling the maf does. set your maf fail freq to zero and go out and get some logs. if it looks the same that rules out the maf sensor. i've seen alot of the lsj mafs going crazy lately.

if the ground wasn't covered in snow and ice here. i would do that.

MAF flow looks fine in the log

[Julex]

Just a side not, why bother changing the afr leaner past your tq curve anyway, to stay safe after your tq peaks drop richer in afr to keep the cylinders cooler, which I run 11.8, which you a hair richer, so it's no big deal. You should be out of gear by 6900 anyways with the stock cams.

I've never ran with the MAF sensor since I got Hp tuners almost 2 years ago.

[Area47]

you're tuning style, and my tuning style obviously vary a great deal.

i know how to fix the problem as it sits anyways. well, now i do after i figured something out.

[SJSchafer]

Pray tell, what did you figure out? Something to do with my fuel maps??

[Area47]

air flow vs pe.

your map has it's flaws in wierd places at high air flow points. weird little spikes here and there. i dropped to the 3.06 pulley and the idc curve is butter smooth, but not so much with the 2,7
