Great results from PCM for Less tuning . . .

[Gottmud]

I just sent my PCM in for tuning. I have 35"s & a K&N air filter. I will give the board a review of the results as soon as I get it back from PCMforLess.

Whoa horsey. I don't make attacks that was just about as silly as your statements. I made my comment because it sounded like a very negative attitude like all these people are lying about their products. Nobody is going to make you buy anything to improve performance. I do know some that dynoed with positive results. It just hit me that "here is somebody else that wants an education by getting people to do the research for him and still be doubtful of the results." So don't worry about it. I personally bought a PCM outright and have one programmed, end of problem.
I also have a diesel and it's a 95 Cummins and it's all mechanical to modify it. No electronic mumbo jumbo you actually have to get your hands dirty. I dynoed it at each stage and the same type of products showed positive results. But what does that have to do with a H3 I-5 except it tows mine real good on long hauls. What the heck something worked!

Fair enough, just asking a few questions, stating a few observations before I screwed with the brain on my Hummer. I didn't know there was a check valve on the dialogue. I'll just take other people's word for things now? I'm not doubting so much as asking pointed questions about what they're doing and how they're getting results that you guys are impressed with.

How much is a new brain, how much does it cost to get it programmed at the dealer should things go wrong? If the tranny pukes a week after it's installed, is Hummer going to deny the expensive claim? The reason I'm making a big deal about this is that I'm probably going to do the programming, just need a few questions answered before I hassle with it.

Keliente what would the cost be to buy a pcm outright with a tune ?

Thanks for replying Kelly.

This is something that benefits you during your entire drive cycle, whether you've got it matted to the floor or not.

Awwww man, I almost went for it. Until I read this paragraph.

First the H3 is not AWD. There is a difference. PCM for less AND Rancho need to get this right before you will get an ounce of respect from me.

Splitting hairs....maybe.

Colorado/Canyon share the same engine, but from the factory they are tuned differently.

YOUR LINK IS TO A 2-3 YEAR OLD CANYON TUNE.

Please provide an updated tune...in private if you must.

teh proof is in teh puddin'.

You're right - it is in 'teh puddin'. Look how many satisfied customers I have on this board and I don't even sponsor it yet

[HummBebe]

Nice....so no updated tune? Even a PM?

[HummBebe]

Can you factor in an additional 500lbs in gear?

I'm not sure what you mean by updated tune? I do each one as it comes in?

Add me to the list of happy PCMforless customers.

I am about as hard-a$$ed when it comes to performance tunes as anyone and more than most. Ask Superchips, Powerchips and Absolut - I have worked with them all with a variety of cars and none were happy with my published and private comments. I dyno'ed my car before and after every single chip change (after doing whatever the chipper suggested was proper break-in) and not once did the dyno back up their claims.

On the other hand, my impression of the PCMforless tune is that "yes" there is modest improvement in power - let's face it 10-15 difference will not be noticeable in vehicles weighing what our H3s weigh. I was most interested in addressing shift points, the lousy feeling of "lugging" all of the time AND having it reprogrammed to account for my 35" MTs. Well, I got what i paid for and am very happy with it. My speedo now correlates with my GPS speed, it doesn't lug as it had, it does feel more peppy AND my gas mileage, which ahd dropped to 12 mpg (corrected for the odometer error associated with larger tires) when I went with 315/75-16 BFG MTs is now back up to 15mpg.

I'd like to know exactly what changes are done to the base map. Spill it all out. I train Harley Davidson techs on fuel injection tuning in my spare time, so I understand maps etc.

If you are not tuning on a dyno and have no dyno maps for the H3, then you are telling me you are winging it and probably doing nothing more that bumping up the timing or slightly modifying someone elses canned maps.

Sounds to me as if you guys are paying half as much for a hand held programmer and only getting a single map and no hand-held programmer. On top of that you have to deal with this loaner ECM crap. THen do it each time you want to make a change? How is this a good deal, I'd like to know?

You guys are paying this turd a rediculous amount of money for hardly nothing. He bought the tuning software, makes a 10 second change and charges you how much?

I tell you what, I will do what he's doing and 10 times better for less money. I will take my wifes H3 down to the dyno and custom tune every cell in the map (which I gurantee this turd does not do!) and completely blow his maps away and have the dyno results to prove it.

Bottom line, if he's not dyno tuning every single vehicle, then you are getting a "canned" map and not custom tuned for your vehicle. Do yourself a favor and just by a hand-held programmer. they are very easy to use. If you want more than that, get the custom mapping done on a dyno.

"I'd like to know exactly what changes are done to the base map. Spill it all out. I train Harley Davidson techs on fuel injection tuning in my spare time, so I understand maps etc."

Why would a tuning company divulge what numbers they change on every tables? How does this make for good business sense?

"If you are not tuning on a dyno and have no dyno maps for the H3, then you are telling me you are winging it and probably doing nothing more that bumping up the timing or slightly modifying someone elses canned maps."

Actually, most real tuners (like LPE) tune so far on the dyno then finalize it on the track/street/strip. The problem is that the inertial dynos (and some other dynos) don't load down the vehicle (or motorcycle) as it is actaully loaded on the road. How do you account for the various riders' heights/frontal areas when loading down the bike when dyno tuning to get the proper aerodynamic drag for proper drivetrain loading? Yeah, that's what I thought.

"Sounds to me as if you guys are paying half as much for a hand held programmer and only getting a single map and no hand-held programmer. On top of that you have to deal with this loaner ECM crap. THen do it each time you want to make a change? How is this a good deal, I'd like to know?"

A Hypertech handheld or Jet performance piggyback isn't going to get you to the customization of a personal tune.

"You guys are paying this turd a rediculous amount of money for hardly nothing. He bought the tuning software, makes a 10 second change and charges you how much?"

Do you know these people? Have you done any research? So far I have not seen any complaints about PCMforLess on here, other H3 forums, and colorado/canyon forums.

"I tell you what, I will do what he's doing and 10 times better for less money. I will take my wifes H3 down to the dyno and custom tune every cell in the map (which I gurantee this turd does not do!) and completely blow his maps away and have the dyno results to prove it."

Shut up and do it. Post all of your table changes. Strap your wife's H3 on to your motorcycle dyno and see what happens. (pssst don't stand in front of the H3) Some simple questions:

1) What load are you going to place on the wheels for each cell?
2) How many VE tables does the H3 use?
3) The programming has a table that adjusts timing for different intake air temperatures. Is your dyno in an evironmentally controlled room so that you can tune every cell in the map for every possible intake temperature from -40 to 248 F (since this is the table range).
4) The programming has a table that adjusts timing for engine coolant temperatures. Do you have a coolant heater/cooler to adjust water temperature (over -4 to 284 F - since this is the table range) so that you can tune every cell in the map.

How are you going to do 10 times better? How do you meaure the improvement - horsepower gain? So, if PCMforLess produces 15 HP gain you are going to produce a 150 horsepower gain?

"Bottom line, if he's not dyno tuning every single vehicle, then you are getting a "canned" map and not custom tuned for your vehicle. Do yourself a favor and just by a hand-held programmer. they are very easy to use. If you want more than that, get the custom mapping done on a dyno."

Why would you pay twice as much for a canned map from a hand-held programmer?

Here's an idea jerkoff, do it, prove it and then talk about it. Until then, you're an idiot running his mouth behind his computer, looking like a . . . may I quote, "a turd"!! STFU!!

The people in this thread bashing the great results of this tune, really need to get a life, or a clue. We're talking about a simple tune to smooth out what comes from the factory, and in some cases, tweaking for add-ons like tires and intakes. I've had 5 different C5 Corvette's with at least 100 dyno's between them, but why on earth would I want to dyno a fricking H3?? Especially if I wasn't installing a turbo or blower?? Nit-picking a $149 tune?? For a reference, I pay $400 every time I tune one of the Vettes.

The good thing, PCM for Less results and their professionalism speak for itself, stands above the internet idiots, and for that I applaud them. Here's an idea, if your skeptical, DON'T USE THEM!! The rest of us are happy.


Thank you, I'm done now!!

Thanks for putting in the good word
