Hi All:

I was wondering if this unit will read injector balance rates on my 08 Duramax LMM. I ask as the ECM has been re-programmed on my truck, and I know from previously owning one for my Avalanche that the unit backs up the ECM S/W, and mine is no longer stock on the Duramax.

Tks in advance ...

Hi Monte:

Tks for the reply, I should have thought it through, forgot most vehicles have two controllers. I guess its off to the Dealership, and see if the TSB I found applies to this situation.

Regards,

Myles

Hi Guy's:

Have an 05 Avalanche on a U7193. Lately a Service Airbag Msg is being displayed on DIC. I hooked up the Predator, and asked it to read the code, and it says there is no code to read.

I cannot erase this code because of this, nor find any info about it. I have read a bit on the internet ...

Tks for the info. I guess I was thinking the tune was held like in RAM, loose the power loose the data.

Good to know.

Hi All:

I was wondering if I every have to change the battery on my vehicle, would I loose the tue tune currently on the vehicles ecm, once I disconnect the battery cables ?

Any help appreciated

Hello 06MonteSS

I am going to replace pipe with a 3", and new Muffler, to one 3" in, and two 2 1/4" out tail pipes. Apparrently the 5.3L needs/likes back pressure.

So I guess next month I will re-check once things installed, and check ltft's, and see if they need adjusted.

These adjustments ...

Hello 06MonteeSS:

I hope the show was good.

I have only adjusted the LTFT's by -1, as suggested by DSLogRedux. I have not adjusted any PE fueling at all.

So I will go another -1 on the injection slope, for a total of -2. No Fueling PE at all in total.

That's pretty good then I assume. Only two ...

Alright fair enough. Take a look when you got the time.

Hello 06MonteeSS

I guess the 2nd run is corrupt, OOP's Sorry. Rats that sucks

Hi 06MonteeSS

Well I managed to log 2 runs with the Predator using Data Viewer. I have attached 2 .CSV files. The 1st one was heading North with a pretty good West cross wind, done from a full stop, stepping on it.

The 2nd .CSV file was heading South with the same rotten cross wind. I managed to ...

Good Morning 06MonteSS:

I will log the suggested parameters with the Dataviewer Software this AM via the Predator.

I do not have DOD, so that parts ok. Sure I will post the log for you, that's great.

Tks

Tks 06MonteeSS for the reply.

I will do my best to get a good WOT in on my data logging. The more I learn, and do the more of a comfort level I have in trying things with the Predator. I am starting to enjoy this.

I will put on a few more clicks 1st, as last night I adjusted the injector slope by ...

So I did some more reading. If I hook up the U7193 to truck, and connect to Laptop, and run Data Viewer. I can use the Data Viewer to Record A/F via the Predator, then save as .csv, and use DSLogRedux to analyze the .csv file to find out how much to adjust PE. I really don't want to touch to many ...

Hi Guy's have U7193

Version: v.9r07 in an 05 Avalanche 5.3L. I have adjusted LTFT's as per DSLogRedux to -1. I know I have to drive again, and do some more logging to check LTFT's again, so PCM re-learns, and they settle in.

Is there any way of adjusting WOT PE for 3 RPM ranges to get a bit more ...

Tks for the Reply:

Your fast ! I don't have those on my truck so we are good to go again. I know this truck can do more with a little tweaking.

I may ask for your help (Custome Tune) after the dual exhaust next month.

Tks again.
