This is done via the HP power tuners software. My guy Jesse has done hundreds of Grand prixs and other GM vehicles. He can do things like optimize your fueling, remove anything you don't want on your PCM, add timing, adjust your fans turn on points for a cooler running engine ect.

He just needs a PCM to map out the changes. His programming is similar to DHP (digital horse powers)

The turn around time is around 6 days. Send it in on a Monday and have your PCM back on Saturday. If your in the Indiana area you can get this done much quicker.

PM me if you want to get this done and be the first tester.

Has he actually changed parameters on a Cobalt or Red Line? I tried pulling the PCM file from my friend's SS with EFILive and it didn't work. I know HP Tuners hasn't cracked the Ecotec PCM yet, and they put the project on hold to crack the LS2 PCMs for the 05 GTO and C6. So I don't think HP Tuners will work unless he's using the cable and his own software to crack the Ecotec PCM. If he has cracked the Ecotec PCM, then there's TONS of guys over at j-body.org that wouldn't definitely be interested. They've been bugging HP Tuners, Hypertech and a few others for over a year to develop software and programmers for their cars.

That's why he needs a stock PCM to work with, to see what he can assess and change. He will be sending the PCM back for the tester stock. He just needs the code to play with. and map everything out.

mail order tuning at it's best. but if software is available better yet.

So no tuning is available yet, he needs a PCM to see if he can crack it. That requires a person here to pull out their factory PCM and leave their car completely helpless for 6 days for something you guys aren't even sure works yet? That's not a completely appealing idea. I think what you guys need to do is either find a stock PCM from a junkyard or buy one directly from GM. I believe all the Ecotec PCMs use the same code. But asking guys to make their new cars 2800lb paperweights for research and development on your part isn't exactly inviting business practices.

Well since these cars are so new how else do you expect to get it done, nobody is currently working on it right now. All he needs is to suck the factory setting off a stock PCM and send yours back. Depending on where you live in the country it could be a little as 4 days. The programming can be uploaded to anouther PCM and tried out by a willing member. Looks like self someone stepping up to help there other club members out would be asking to much :rolleyes:

If you have 2 cars then it's really a big deal.

I would be interested but I am not going to turn my car into a paper weight to be a test subject. Sounds like your friend needs to buy the car or hook up with one of the tuner shops that already has the car.

Obviously you have no clue. It's not as easy as just "sucking the factory setting from the stock PCM." The PCMs have locks that must be bypassed or cracked. And if he's using HP Tuners software then he can't pull the code. I know how easy it is as I do my own PCM tuning on my LS1, but it's only easy when you have the right software. Just because it's GM doesn't mean HP Tuners will read it. I've already tried with Flashscan. I'm all about pioneering and being the first to try stuff on these cars, but you're up here talking like this is a definite process and you've already done it. It's not that easy. If your friend is a PCM guru and has already cracked the Ecotec PCMs then by all means spread the word and start tuning, but to post a message talking like you've already done it is misleading to these guys. That's all I'm saying. Your post should read "Need volunteers to give up their PCM for Programming R&D." It's very easy to "kill" a PCM many LS1 guys in the beginning with LS1Edit killed their PCMs because of power failures during programming and other problems. PCM cracking is not an easy task which is why these companies go through so much beta testing BEFORE software is released and even after its release there are still updates and revisions for certain situations. You still haven't clarified what his process is, and your original post says he's using HP Tuners. HP Tuners does not support these vehicles. They support every other GM vehicle American and Austalian, but no j-bodies, LSJ, or Ecotec. What are you going to do when someone sends you a PCM and the results aren't ideal? I.E. you can't program it or worse you fry it. You can catch an attitude all you want, I'm just looking out for the guy here who doesn't have knowledge in the PCM area and would be misled by your post. For the record, I have 3 cars and yes it would be a big deal sending my PCM to someone I have no idea about their business practices, technical skills or reputation. Are you going to insure the PCM sent to you? Or is it going to be at the volunteer's own risk? You make it sound like it's cake to crack a PCM when it's not. This is especially true when you're using another company's cable and software. Have you reverse engineered the HP Tuners cable to work with the Ecotec PCM? Have you an insider in GM that gave you the key to the PCM lock? Are you planning to do that with someone else's PCM? So many questions but no answers, only smart ass comments. Believe me, if it were that easy someone would've done it already. If all the Engineers at HP Tuners had to do was swap a few wires in their cable they would've done it a year ago and sold cables to the hundreds of j-body owners out there that need tuning. Those guys are using Megasquirt, SAFC, EManage and other piggyback units to tune their forced induction GM 4cylinder cars. All I'm saying is "fellas be careful of who let work on your car, ESPECIALLY the PCM." And like NIVO88T said "mail order tuning at it's best", the best mail order tuning is maybe a night tremor as opposed to a nightmare. Having your car's PCM tuned several hundred miles away isn't exactly the BEST way to go about it. This message would have been completely unneccessary if you would have clarified, even a little, that your friend has already done it or has a VERY GOOD idea of what need's to be done. But since you didn't I consider you to be just "talking out of your ass". And that's all I have to say about that. :eek:

Fact 1, I said he would be needing a PCM for a tester, Not that he broke the code but was willing to try. He has not played with these particular PCM's yet. If it would satify you big man. How about some one track down a PCM from a wrecked ION Red Line so we can can get it looked at. Would that please you more. Did I say I was the tuner, did I say he broke the PCM code, Did I say it was a sure thing? No I said he wanted to take a look at the PCM, see what code he could pull so he can look at it. That's it and nothing more.

Why is it people on car forums get all fired up when there's nothing to get fired up about.

Get of the Juice. :rolleyes:

So we'll go this rought since Mr. Angry want to bash everyone. Can some one track down a wrecked ION Redline with a PCM at your local salvage yard or online.

Thanks

The 2004 Ion Redline PCM isn't the same as the 2005 ION Redline and SS/SC PCM from what I have heard.

You consider asking for more information "bashing"? Now I'm "Mr. Angry". I'm just merely making it known that it was going to be a waste of time for someone to send you their PCM when you're using HP Tuners and haven't modified their cable. But whatever. The 04 and 05 PCMs are the same, they just use a different calibration. Which I think there is an update from GM. If you crack an 04 PCM then you would be able to read the 05. Actually I think if you crack any post 99 4 cyl PCM you could read the 04 and 05 PCMs. I could be wrong though. ArrivalBlueSS where are you located? I'm pretty sure there are some LS1 guys in your area with HP Tuners. Find a shop that uses HP or someone that has a Professional license and see if they can pull the calibration. My Flashscan from EFILive might do it if I had the key. As soon as I start the download it gives me "PCM Locked" error. Right now our best bet using a piggyback controller.

What Is It U Need To Crack? Any Info I Can Swipe With A Tech 2 To Help U?

Ahh, the lovely and wonderful TECH2! I wish I could get my hands on one of those! I'm not sure though. When I tried to pull the file from the Cobalt it asked for a key. My software was telling me that the PCM is locked. Can you pull up keys with the TECH2? Or even better yet, could you download the PCM calibration and send it to me? Maybe we need to PM each other and see what our options are.

let me know ill do what i can but something i thought of last night. is even for us to use a tech 2 we need a candi module to slow the info down to tech 2 speed because the the cobalt is built with a class 2 high speed data link purpose being it will be tech 3 compatable in 07 u might need a simular device to crack the pcm

Agreed. If this guy want to make a business out out of reprogramming perhaps he should purchase the module from GM. If he can not do this because he is a "basement hacker" I would net send him a part out of my new car.

I haven't seen anything about an aftermarket PCM for the LSJ, but if anything comes out it will be a stock PCM modifying software that really sells and will be useful to the enthusiast. Hopefully HP Tuners or EFILive will release something that we can use to make changes to the stock PCM.

I've known Keith at HPTuners for a couple years now. Way back from the Midwest F-Body Association days. He was actually using the converter out of my '98 Z when he set the LS1 stock internal record of 10.98. Anyways, I had offered to send him the PCM from the Cobalt SS and possibly even the whole car if he needed it. He stated over IM that he is working on it and has everything he needs at this point. I don't like mail order tunes, and prefer to do things myself. Hopefully the layout will be as easy for these cars as they are for the LS1 cars.
