im still not seeing anything to do with the injectors in the pid's

hmmm... well, if you don't have any fuel injector parameters to log, then there's no way for you to tell what your injector duty cycle is at...

interesting...

are you interested tuning my truck i could even send you the tune its running now?

send me everything I'd need and I'll take a look at the files... if there's anything I can do, I'll letcha know, and we'll go from there...

I need a copy of your stock original backup tune file, and also a copy of the current tune that's in your truck right now (the Last Tune Written)

sound good??

sounds good sending info now

lew is the man he did in one try what my other tuner has been trying to do for 2 months he knows his sh@t when it comes to tuning with a diablo tuner

thanks man!!

bump!!

Bump!!

Lew,

I last posted at "efan control for 2004 Silverado with u7193".

I finally got out on the freeway today (went to Monster Jam in PHX) and did some logging. Ran the numbers through DSLogRedux and it came up with LTFT Bank 1 (12.71401%) and LTFT Bank 2 (11.79003%). I am going to lower the slope to -13%. I attached the log, before adjustments. My only worry is that there may be too much fuel and cause knocking at lower RPMs.

It's an 04 Yukon with K&N 77 Series CIA and Magnaflow cat-back (single).

It already experiences knock between 3500 - 5000 RPMs when at WOT.

I'll lkeep you posted.

if your ltft's are at +11 and +12 now, then that means you're pretty lean, which is why you're probably knocking at WOT...

so, adjusting your slope to -13% to get your fueling straightened out will be fine...

Well the injector slope adjustment seemed to cure the knock, but I still need to drive it a little more and then do a log.

I did notice that that a little more throttle is needed for the kick down from 4th to 3rd (40 - 45 Mph). The lugguing is a little more evident.

I just bought a new Diablo Predator for my 2009 Vette. I installed the Performance tuneand drove it for about 115 miles. I decided it was time to do a data log to see what adjustments I may need to make.

I have version U7194.

I Follow Lew's directions and attempted the log the following items:

air/fuel
command throttle
engine speed
intake air temp
longterm fuel trim bank (1&2)
MAF Sensor
Spark Advance
(couldn't find Throttle Knock Spark Retard in there)

I got on the hwy and did the view/record and it only logged about 2 min worth of data before it was full. I thought that was only an issue on the older models. Anyone know what the heck is wrong with this thing? I bought the newest version to make sure I wouldn't have any problems.

yeah, just download the log to your pc using the dataviewer program...

Yeah, I figured that part out finally. The dataviewer so far just says I need to adjust Inj Slope UP by 2% (+2) & make a PE Adjustment -2 %. But my main concern is, is 3 min worth of data logging enough to go on? So far I just adjusted the Slope...not sure I'f I'm suppose to adjust the PE based on the hwy cruise log, do you know? Do I need to do any data logging at WOT?
