Great results from PCM for Less tuning . . .

Please explain to us how this "personal" tuning is accomplished/accurate when they are done in-house and not on a track or dyno? Where the initial maps created at least in this fashion? This would be an acceptable approach, providing they are down-tuned to allow for variances in weight, wind, towing etc.

We were not getting the answers we were looking for, thus I am assuming is the reason you posted. Please explain the above. Thanks!

Kelly is perfectly able to answer these questions. However calling her/us names is not the right way to initiate conversation with anyone.

GM puts tons of nanny controls on the PCM. They also tune for the worst available gas (lower than 87 octane). On top of that they set the trans shift points up so soccer moms don't complain because they can actually feel them. You have to think in terms of GM. They do not know if you are going to try to tow big loads around, totally abuse the truck, or run the worst gas you can find.. All they know is they have to replace hard parts if you are that 16 year old kid that likes to do burnouts and donuts. Therefore they put a nanny settings in all production vehicles.

We ask questions on the ordersheets about your towing capacity so we can get a feel on how you are going to use your truck. We also have 3 different shift maps including firmness, TCC lockup, and trans shift points for you to choose from so you get your taste in shifting all the way from weak to firm. We also have around 17 different base programs we pick out biased on your modifications for different intakes, levels of modifications to the exhaust. We also have 3 different settings for towing which changes how we set up the shift points (again), how much part throttle advance we run, and what AFR we set to target on high loads.

This goes on and on.. I guess the best way to get a judgement on what we use to build a custom tune is to get on our website and look at our ordersheet.

We have worked this down to a science with R&D vehicles and TONS of experience tuning everything from totally stock vehicles to cars like a 99 TA that runs 9.77 naturally aspirated, 93 octane, drag radials, and chambered exhaust. (You should see that very soon in a GM high tech article titled "LS1 vs. LT1 shootout"



As for the other question H3's are full time 4WD. I think Kelly said they where AWD earlier. Don't you think that is kind of a nit picky thing to try to demean her with?

You can find our physical address on our website under contact us. Pick your vehicle and it will show you what address serves you.

Also, I don't think the fact that Kelly is my wife (in a couple months) and we do live together is any of your business

You two living together in sin() isn't the issue. Two users that are promoting something and share an IP is highly suspicious. We've seen hucksters try it before.

GM is not doing anything uncommon...All production EPA approved vehicles factory tune in this manner.

And get over the turd comment. You guys keep bringing it up after I admitted/apolgized it was off base quite some time ago. Jeese....

So from the way I understand it, you are saying that you are picking from pre-built maps based on how the customer responds to some questions.

So there is no custom tuning being performed and these are all base/canned maps assembled togther into one load.

You see, at least when I do it from Harley customers I have them a data recording and send me their data file first so they are actually getting a custom tune and not something I assembled from some questions they answered. I have them do this before and after file creation to ensure the knowck sensor does not get activated (something you will never know without ECM data file recordings)

You answered my question. Thank you very much!

I live in Montana, let me drive to North Carolina or several states away for a personalized on the dyno tune........... a 4WD dyno at that

Oh and tomp, you mentioned temperature, etc. in custom tunes.

Well here in Montana where I live the temperature goes from -40 to 103

Does this mean you'll STFU and be gone like you said you were like 5 posts back?

I admitted I was splitting hairs when I said it. All she had to do was correct herself.

Just like the guy at 4 WHEEL PARTS, who swore up and down...argued with me that my H3 had air ride suspension, that it was spring over, and that it was built on a trail blazer platform.

Rancho lists the H3 as an AWD vehicle. The same guy at 4 wheel parts, sold me my shocks after I told him my Torsion bars were turned in order to accommodate my 35" tires.

He sold me the shocks, but said nothing to me about "custom applications" not being warrantied. No biggie, I didn't throw a fit, I just replaced the shock 4 times at $90 bucks a pop.

Will I buy Rancho again....no way. Will I shop at 4 Wheel Parts....not a chance.

So the moral of the story is....Be suspicious of people who tell you the H3 is AWD.
