Did a little logging today
 
did a little logging today looks like i have a pretty strong fuel system. turned my pulse width up around 2600 just to experiment, i was able to hold 22,500-23,000psi at 24XX pw. One thing i cant figure out is i never see more than 85 or 86mm3 event though my base injection qt. is 110 at 100% TP

Here's a couple logs i took just short bursts around town. The latest one is with the PW turned up.
The tune is my normal DSP5 but i raised the PW on the Stock tune to see what i RP i could hold.

turn up table B0728, you are requesting more fuel but B0728 is limiting all the tables including B0751 and B0727

might want to give B0747 a look also its going to limit the amount of fuel when you go faster.

log a WOT run with these pids.

Shoot me your email and ill send the pid list to ya

Thanks for the pid list, I looked at B0728 but its all at 100mm3 so why is it i can never see over 86 this table should let it go right up to 100 right? Is it something to do with the defuel tables?

2500HeavyDuty 10-29-2008 01:55 AM

:duh3: they do limit how much fuel is getting to the engine also, if you log GM.Max_trq_dma i bet it would point right to why you are seeing 80mm3 in the logs.

Look at B0741 there's your problem. with that amount of pw and rp you might limp the trans when you turn up that table

uwyo_dmax 10-29-2008 02:04 AM

yep that would make sense I should have thought of that sooner :argh: This stock trans thing really sucks! i was out playin around tonight found a LBZ with edge hot could hardly beat him with the 5th pos. tune on there :dang:

2500HeavyDuty 10-29-2008 02:09 AM

yeah looking at ur dsp #4 and ur trq limiting your only running like 20-2100pw on that tune. gotta be ways to tune to save the trans. and yeah stock trans sucks.

Sell your lift to me :D ill give ya like 500 for it towards the trans

uwyo_dmax 10-29-2008 02:19 AM

haha I've become rather attached to the lift :U: Guess I'll just have to be nice to the poor ally till summer when i can get a real job again. When I was running that guy he seemed to get me of the start, but that tune seems to pull real well on top by 55+ i mine would pull on him pretty quick.
Did you do your SCIV yourself?

2500HeavyDuty 10-29-2008 02:20 AM

nah, its the only thing i didn't do my self.
