please read this and reply with your issues IF your VIN falls into this group...

If the 11th digit of the VIN is a 2 and the last 8 of the VIN is less than 52114278 or if the 11th digit of the VIN is a 6 and the last 8 of the VIN is less than 56105324, reprogram the PCM with the latest calibrations. An updated engine calibration has been released to address this issue (intermittent stall or near stall during low speed deceleration)

Mine hits it, no issues.

Thats because your Westers tune includes the latest GM updates at the time it was burned man.:D

Thats what I figured, but I was wondering what the date on that bulletin was. I had my original one flashed right before I got the westers, never had any problems with it either though. I did have it go near a stall once. I cleaned the throttle body and it hasn't happened again. Just wondered if that was a new release or something.

Yeah, and nice sig man! ROFL

Yep, and usually cleaning the tb will take car of that, but not always.

[rhilyard]

Of coarse mine would be one. :ugh: But I did think something last wrong at idle it would almost die. Now the next question is will GM charge me for this?

[Jozuah]

well, unless its covered by the emission warranty sadly yes. around 75.00 but heres the deal.
for another 50.00 or so depending, you could get a tune that comes with the latest GM calibration.

just a thought.

Called my Dealership they said that it would cost 60.00 plus tax. And about an hour to do the programing. Want I would like to know will this help with gas mileage? I just Installed spark plugs last weekend thinking that was the problem. Guess I was wrong. :duh:

[LOWRIT00]

Mine is right here too, and I do get a sudden drop in rpms but not a stall if I get the PCM tune the new tune will come with all the newest updates ? Is that correct ? thanks in advance

yes that is correct, well i can only speak as to PCMforLESS i have no idea about the others, scarabepic might be able to confirm this.

they build their tune off the latest GM cal. and i can say without reservation it makes a HUGE difference in the final result.

My TB's VIN falls into this, however I do not have any problems.

Did this update just come out? I bought my TB in February ... could this already have been caught and taken are of? Or, has it just not happened to me yet. I am at 54,9xx for miles.

Thanks.

[regularjoe]

my vin falls under this also and mine has stalled and i have the ses light that flashed once real quick once in a while.

[DrumMedic965]

... i have the ses light that flashed once real quick once in a while.

Mine did this for the first time today on my way to work. Wasn't even on for a second, but I did notice a hesitation also when it did this, but after it did it that one time, I didn't have any other problems. It didn't stall, and didn't do it again.

Jason: Might be time for PCM Tune's ... not much more than having it re-flashed by a dealer lol.

i would ask your dealer about the origin of this concern, im not a dealer and dont want to lead others astray

Alright. Thanks a lot for the info!

[ScarabEpic22]

I know PCM4Less uses the most current GM cals, Im pretty sure Wait4Me and Westers Garage do as well.

This is the entire reason Ive been advocating PCM4Less tunes so much, they are only ~$80 tops more than a dealer update plus they give you so much more performance. To me its a no brainer, save for an extra little bit and order a tune instead of getting robbed blind at the dealer.

[Mafia4life]

I just posted a thread about a couple of days ago on this same issue and what do you know I fall under this. Time to bend over here comes the dealership with no vaseline.:hissy:

[SIK ENVY]

my Voy has stalled bout three times now. I thought it was just sleepy. I guess I'm gonna get a tune from PCM4less. to be honest, I have no idea what it is or what it consists of. but I'll figure it out. :undecided

[BLAZEN03]

Mine falls into this catagory also. I'm going tothe dealer this weekend for service, I'll ask about this issue then..

[ssmontecarlo82]

My truck's VIN falls into this grouping. Its never outright stalled, but there are some times when the RPMs fall very low and it almost stalls. I'm interested in more information about this PCMFORLESS deal that a lot of you have. How much and how is it done exactly? Is there a website?

Thanks!

Dealer=:no: :no:

PCM4Less=:yes: :yes:

If you are going to pay the dealer anywhere from $60-100 (I was quoted $100 for a reflash here in Seattle), why not spend the extra $50 or so and get a performance tune that includes the update?

WWW.PCMFORLESS.COM <-- best decision youll ever make for your trailvoy

as i have stated its like a sport version of your already killer truck.

Drew: i think your correct.
everyone that goes to a dealer let us know what they said> I would have to agree i they want to reflash i will just go with the pcm4less for a little extra money. i will have to do a search to see what is the best stage tune to get it is a daily driver and i do tow so i dont want anything too agressive.

[ssmontecarlo82]

I just got off the phone with Kelly (very helpful). I'm going to get this done, but I need to find someone with a Tech 2 here in Michigan to do the CASE re-learn.

My truck is a daily driver. My only complaint is that the truck can't get out of its way at low RPMs. My question for you PCM experienced drivers out there is what stage/options should I get for my PCM? I would prefer not to have to raise the octane needs of the engine.

Thanks!

I doubt you'd have to switch Octanes just for a change in computer programing. Octane requirements are more Dependant on on actual combustion chamber environment than anything else. compression is a big one, manifold pressure is another, chamber temperature is a little less, but still plays it's part... i wouldn't worry about it.

that is unless the PCMFORLESS.com peeps say otherwise...

[jag42420]

I just checked my vin, and I guess I'm one of the lucky 'needs a reflash people'. I have had a stumble at idle a handfull of times, but never had any loss of power. I see now I'm not the only one. Time for a PCMfor less tune I guess. I shot them an email to see if they can email me a tune I can flash myself...

im curious what a case relearn is? can anyone help me out...

[jag42420]

What is a CASE relearn?
CASE (Crankshaft Angle Sensor Error relearn) is an advanced way for the truck to
detect misfires, using the crankshaft and camshaft position sensors. When a
computer is completely rewritten with the latest GM calibration, the CASE
information is lost. To relearn that information, a dealership or a shop with a Tech II
scan tool must perform the procedure, which takes around 5-10 minutes. The only
time you need a CASE relearn is when using our core program (option #1). The
check engine light for the CASE relearn is disabled on our loaner PCMs, so that it
will not illuminate. This does not hurt performance nor disrupt driving in your truck.

[xDAVEYMACx]

hey thanks for the info jag. im new to the whole tb scene and have no clue about pcm's and all that electronic stuff. im gonna have to get the core system it looks like..i have no time for downtime.:crazy: :crazy:

[jag42420]

Everybody's a newbie some time. I'm not much further ahead of you. I bought a 02 WS6 Trans Am, and am learning the PCM to keep it tuned as I mod it. That's what these forums are for!:laugh:
