Hey Jon

I have a 2009 Escalade engine and ecm, coupled to a t56 mag trans. I have a small problem where the gateway I use to operate the dash only speaks Truck GMLAN. I tried flashing the vette...

5w30 Full Syn, 3bar tire pressure when hot, and the windows are up.

i am getting 400-450km per 75ltrs of fuel.

Needs to stretch a bit further

Running 100mm MAF, 90mm TB, Compcam 689-421-13...

I am tryin to stretch my tank to last a little longer,

I am lookin to try 14.83 as an afr, what is the MV for said AFR, 120mv???

Looking forward to your replies

Keith,

Have another one for you, i upgraded to the 3.0.64 and i am unable to find any VATS control. I can disable in the OS, but i cannot relink the vats, or change the vin number, or change Vats...

Ok, I have a situation where my ECu is shutting off because it cannot find the bcm so I disabled both vats and the car still will not start after a full write calibration. I'm looking for the relink...

thank you Russ,

i just tried out the truck annd its runnnin perfect...

Thank you Russ,

I made the changes you mentioned, will try them out and revert back to you...

Here is my stock tune

I recently bought a Yank 3200 SC multidisc tc. I got ride of some stock issues that would cause the tc to fail.

I lessened all my shift times to 0.300 with the exception of 1-2 where i kept it at...

I did that with no positive returns i am playin with the commanded fuel at crank, noticing that the rpm startup is better but i also need to fiddle with the cranking air so it doesnt surge

When does ur maf kick in? Make sure you have it activate around 3000 rpm, the ecm reads the maf regardless, keepin it high keeps u from surgin at low revs

I lowered the crankin air to the point where the car starts up flawlessly but the rpm always jumps to 1500 then drops to idle speed. The only thing i did was increase my idle timin by 2 degrees.

I do have an auto, but the power delivery wasnt smooth and when i towed it surged and it was bad...

Intake manifold leak would do that...Or a hole in one of your hoses from the intake tube to engine or from engine to intake manifold...

If you have a readout from the MAF its working.

Your...

Increase the airflow delta, and MAP delta...

There might be a situation upon startup that has the ecm thinking its a run away engine and reducing the throttle for your protection...

wheres your trim, your MAF is all wrong...

Plz activate your Trim and adjust your MAF. Later install a WB and tune for 12.2-5 AFR at WOT from 3,500-Redline. Your fluttering will reduce and your

I agree, i have a 102mm MAF with stock MAF sensors.

Log your STFT and LTFT take 75% of those additions and use that number to increase your MAF by %. If you have 2 stft and 8 LTFT you add then...

Plz try copying parts of my tune,

Copy the following

Target idle speed
Idle speed max
idle speed min
Airflow min
ETC area scale
Max fail

At low rpms, what does your LTFT and STFT look like?

If the tune is incorrect the you would have the same effect, also what rpm did you have the MAF activated? If its 500rpm then try increasin to...

IAT wont have as much effect on knock unless the tune is incorrect. I have had my IAT up to 75c after a few forth gear pulls on the road.

Plz install a wb and log properly at high rpms...Your LTFT...

Research for the next guy...

If you have a pre 2009 Actuator/phaser you need cam 156, if you have a post 2009 phaser you need 189 cam from compcams....

If you use the 156 on a post 2009 phaser...

Not very happy, i have a kid on the way and this is starting to bother me. Ever since i max out the retard the truck just started to feel better.

I will look for a shop here to dial in the cam, i...

What is your idle timing table, High octane table and coast table look like?

Also did you tune your MAF in the Idle zone? Also where does your MAF turn on?

Ok, i understand the theory behind the numbers, the higher the number the more retard from MAX advance we are getting. Thus in my situation if i have +7 then its 16-7=9 degrees of advance.

Now i...

Ok, i researched my phaser pn and i know i have a hybrid phaser from 52 retard to 16 advance with limiter fir 20 degrees of change i also have a 189 for i installed it personally, its cca's stage 3...
