Good for you on the side job... I am not schooling you on anything, but please take things way out of context as you seem to want to rant on and on about this.

And I do know that you cannot do FI on the PCM's in my truck or other TB/EV's like it without some MAJOR supporting steps because the PCM cannot support more than a 1bar MAP sensor. The PCM change in '06 (with the addition of the MAF sensor) opens up that capability, but not on the '02-'05 PCMs.

Lets just stop the e-fight right here and now. For EVERY thread you produce, I can produce a counter that has MANY people that are VERY happy with their tune from PCMforLess so that is a completely moot point. With any large company, there are bound to be people that do not like what they received. In the end, anyone that is looking to do something like this should do their homework. That homework should include specific reviews from people with the exact same engine. Take information or experiences with another engine with a grain of salt.

You know, in all of this ranting on and on about how bad PCMforLess and Wait4me are, you have not answered the one question which I would expect someone with your knowledge and experience to have answered... What is your recommendation for a mail order tune?

 

im looking at a file for a 06 buick right now. Yes you can add boost to it, no there arent options for different operating systems as in 2bar or 3bar however you can use the MAF to tune for boost. So yes it can be done.

you can show threads of ppl them doing a tune on a little stock 4.3 blazer. Once you get mods they cant do ****. You can see his lack of support on vehicles that make power. I could scan every single one of PCm4Less tunes and show ppl what hack work he has done compared to a stock file


as for who i recomend? if i had to recomend anyone Nelson performance out of san antiono texas is a good tuner. Blackbear performance is another decent name, wheatley performance all names pop up.

 

Using the MAF to tune it would be a little difficult... Might want to check your sources.

 

Its been done, i prefer to tune SD but MAF is still an option

 

Well, the problem is that '02-'05 == No MAF so it would be kind of hard to tune with the MAF...

'06+ use the same PCM as the Cobalt SS so they have support for the 2 & 3 bar MAP sensors and also have a MAF sensor so going FI is relatively easy.

 

yea those earlier years goes off throttle position for fueling. I tuned a turbo cavalier like this. Its not the most accurated or precise control for fueling but it is possible to tune for boost with a setup like this. With a setup like this you have one desired boost level and tuen for fueling in the 100% throttle region then taper it down so your fueling is correct for anytime the motor sees boost

it can be done, i can show you a screen shot of the tables im referring to

also my point for speaking that way about Pcm4Less on the other sites is cause he has been ran off them for his shady/hack work. If his sponsorship has been pulled from those sites what does that tell you about him?

 

While it may be possible in that sense, it is not the best nor easiest with other options being quite a bit easier and better for overall performance, especially for daily driven vehicles. Many convert to the later PCMs to have it work properly for all conditions. Takes a bit of knowledge and work, but it is possible to convert.

The thing with the fullsize trucks, f-bodies, etc is that there is a HUGE aftermarket. Sure, the guy probably did some messed up things to try to account for mods that people had done, but you have to admit, to tune a vehicle that you haven't personally seen or scanned is difficult. It is quite easy to run someone from a site. There don't even have to be very many complaints with the way that e-fires go. Once the band wagon starts, it just gains momentum. Its like an avalanche. That is the nature of the internet. Many problems are mountains made out of mole hills.

Back to the topic at hand, who would you recommend for PCM tuning?

 

i stated who i recomend. Nelson Performance if i had to go with a tuner

also i have 3 customers in texas that ive tuned viva Emails. I never seen those trucks till past weekend. I was able to dial them trucks in very well. If you know what your doing you can compensate for things. One of those customers of mine is a rear mount 76mm turbo setup.

i wouldnt let PCM4Less tune my snowblower

 

Edit: Nevermind, I found out it will be $75 for my tune because I have another ecu from my other truck so I can keep my one now stock and have my other one tuned. Man am I excited!
