LS1/LS2/LS3/LS4/LS7 etc. - LOGGING, ADJUSTING INJECTOR SLOPE

[06MonteSS]

no, the PE fueling is for when you do a WOT log... when you're just cruising on the highway, you're not in WOT/PE mode, heh...

yes, 3 min. is enough as long as most of the time was done at the proper logging scenario...

when you run the log through dslogredux, how many rows of data does it say it has? should tell you under the average ltft numbers...

[CyberGreyVette]

It says "Number of Cruise Data points: 35,643". The Excel spreadsheet shows just over 21k lines of data. Is that good?
I'm sure there is a page on here somewhere that tells me how to do the WOT datalog for PE adjustements too. Do you know where I can find that?

[06MonteSS]

do you have any instant messenger??? that would make things a lot easier/quicker...

I have AIM, yahoo, and MSN messengers, so I can do any of those three...

PM me your screenname if you have one..


also, email me your log file at [email protected]

thanks!

[CyberGreyVette]

I just sent you my log file. Downloading yahoo! IM now.

Update *** IM ID sent to you via PM

I've got to go back to work but if you send me a message on Yahoo! I'll respond when I get back home.

k, actually... your excel file has over 50,000 rows of data... PLENTY! heh...

after going through it manually, plus running it through DSLogRedux, there are 36,011 rows of usable data... still PLENTY!

based on your log file, you need to go +2% on the injector slope adjustment...


and don't worry about any WOT stuff until you get the regular/normal part-throttle fueling dialed in...

and WOT logs you need to do separately from cruising logs anyway...

[CyberGreyVette]

Aweome! I made that adjustment yesterday so I'm going to do another datalog tonight and see where I landed. Sooooo, if i'm all dialed in there I can move on to the WOT stuff.

What is the file extension supposed to be when I export the Custom tune to my PC?

I have the options of .lan and .bin

[fernanbfg]

Never mind I used the DS Downloader and got it to export.

Need to figure out how to get my 2004 chevy tahoe tuned completely right. I see everyone talking about LTFT and injector slope and all but Im still new to this language. I had installed the 93 octane tune into my truck and it seems slow at low range. I have magnaflow cat back with a flowmaster 70 series. TB spacer, KN CAI, new plugs, wires, filters, syntheic mobil oil, and Im planning to get under drive pulleys soon. Can u direct me to adjust my settings correctly please. Thanks

[06MonteSS]

do you have a newer version predator that can save data logs? if it's on a 9rXX revision, then you can... when the predator boots up and is at the main menu, there's a number at the top of the screen... that's the revision number... what is it?

if it's an older 2.xx version, then you can not save data logs, but you can still monitor the parameters and watch them live on the screen while you drive...

here's info on what parameters to log/monitor and how to adjust your injector slope to get your average LTFT's (long term fuel trims) in the 0 to -2 range...

http://diablosport.com/index.php?name=P ... opic&t=917


after getting that dialed in, you'll get better throttle response, better accleration, stronger pull, and better mileage...

for even more gains, you could get a custom tune created for your truck, and get even better performance.... contact me if interested...

Ok, here to help out Lew...

In the Trinity and new revision 7194 Predators, the logging/monitoring parameter listings are now all under different sub-menus.

This guide below can be used to locate the necessary parameters needed to log for a custom tune...


Air Fuel Ratio (Equivalence Ratio) = Under FUEL menu

Long Term fuel trim bank 1 = under FUEL menu

Long Term Fuel Trim Bank 2 = under FUEL menu

Spark Advance = under IGNITION menu

Intake air Temp = under INTAKE menu

MAF Sensor Mass Air Flow = under INTAKE menu

Total Knock Spark Retard =under MISFIRE menu

Engine Speed (RPM) = under PERFORMANCE menu

Commanded Throttle position (or Absolute Throttle Position - for older vehicles that don't have the Commanded parameter) = under THROTTLE menu

NICE man!! thanks!!

I made your post a sticky at the top of the Predator GM Gas forum, as well as the Trinity GM Gas forum...

woohoo!!

[aviraled2002]

sweet!
