Default Engine Control Module ReWriting

This is in the pub, because of the traffic.

I dont get on much anymore, as my hobby has taken back burner to work.
Trying to help another start-up guy ive met, that is in the auto field.

He is an experienced ECM guy.

I need the ECM re wrote on my truck, and have looked at about every option avail.

He is willing to buy the software nesc. to begin writing ECM fuel and spark curves. He doesnt have a dyno, but if we make him busy enough, he will buy one. His shop is in waterford.

Tomorrow, I meet with him to order EFI Live for his laptop, and the cable nesc. to do OBD2 programming. This means, live, local tunes, for less than the top guy, without the ECM swap headaches of mail order.

I guess the point of this post, who, local to waterford, is interested in an extra 50hp from your stock truck? Its possible by turning TQ mngmnt off. He is willing to do as many tunes as possible, for a "start up rate", to pay for the investment of buying the software to allow him to do this. My truck, with a new crate motor, will be the test pig. He has the software at his disposal now to do mine, but he doesnt own it. When I called him first questioning if he could do it, he was excited. His passion, was called upon during his start up year.

If your at all interested, post it up. If your serious, PM me and we will all meet and talk at his new shop.

I guess I'd need to know more about what "experienced ECM guy" means. I've calibrated and wrote code for 4 different companies, and there are a few things to watch out for when you start turning knobs.

NOT saying the person you mention is inexperienced in any way - especially if he is willing to invest in a chassis dyno - just that some people will work with open ECU on a couple of Subies and proclaim themselves "experts".

Personally, if myself, JCR, Topheavy, and Jesus could afford the $$$, we could open up a boutique tuning shop that could put any powertrain in any car, tune it whichever way you wanted it and give you full modern instrumentation and capability.

There's big money in that, if you can find a population wealthy enough to support it. Your guy is definitely on to something if he focuses on the low (affordable) end.

I'll gladly pay $500+ to make sure my $6000+ engine stays alive long enough to appreciate it. Sorry but theres not a chance in hell I would trust anyone that "does it cheaper" than the best. I have EFI Live and I use it to tune my diesel, I've spent a lot of time figuring out what everything is and what it does. It's really easy to screw something up even if you have half a second of a brain fart. I am going to have Vector Motorsports tune my engine when the time comes. They are also one of the biggest and most reputable shops around for Gen 3's and 4's. They have a dyno that is needed to hold steady state conditions and get the A/F ratio spot on. You can only do so much tuning on the road. You can get the drivability down pretty well but you can do everything.

Westers or something like that has the gas engine market for trucks pretty well covered and the other people that compete with that are cheap enough not to question.

People with stock trucks can buy off the shelf tunes because they are reliable and consistant. The only people really needing individual tuning are the ones who have lots done to their engine and an off the shelf tune isnt going to work for them. They are also the people who arent going to cheap out when having it tuned. I know many people who have $20k+ into just their engines and they gladly pay in the thousands for reputable tuning.

If your buddy is going to do engines he should learn transmissions too. They go hand in hand. Prepare for an expensive learning curve!!!

Good luck.

I recently found a guy in Grand Rapids doing something simular. He rebuilds ecm's for a living and tunes them on the side etc.. He has his own motor that is a 6.0 with a supercharger on it, in a 71 cutlass supreme. He is loking to do tunes as well.

I think it is a good deal to get into, but takes alot of practice to get good at???

Ok......the topic ive been looking for info from this site finally came out.

I have asked a few times about this, as I have a GMPP350HO in my 98. I have drove it for a year now, no issues, so i didnt shell the coin as I didnt really have it. Truck is now going into snow plow mode. I want everything right. It gives my slight driveability issues when starting warm. And the TC isnt unlocking now.

I was thinking of splitting the cost of EFI Live with a friend, as he needs a tune on the same type of truck, and we were gonna try to learn it.

Blackbear or Westers was my next option, but I dont want to mail order as that seems like a headache swapping computers constantly.

A few people around here recommened the guy at Howell EFI, but then a few have said NOT to go there.

I guess my guestion, would you be interested in tuning my truck 95Geo?? If so, name a price. Or any of you other ECM gurus. Unfortunatlley, I dont have a bank account for my truck, but I want it right. I wont mail order it as stated above. I would rather use a local guy, but I dont want my motor melted down either.

I don't have a way of tuning your truck, or I'd love to teach you / help you do it for free.

Thats cool.....

I had seen you were offering fab work on the side, thought maybe you might want to do some ECM work too.

If you didnt do your own stuff........who would you have do yours? My choices are:

Blackbear
Westers
Howell EFI

If I buy EFI live and the cables, would that be the way of tuning it you dont have?? If so im almost interested in buying the software and learning to do it myself.

I don't have EFI live and the cables - plus I don't know what software EFI live uses, or where they poke the changes to.

If you buy the stuff, I would be happy to spend a day teaching you the basics and helping you build a tune for your truck.

I appreciate the offer!!

What kind of software would you recomend.
I have been reading online about what needs to be done, but I am by no means educated as to what needs to happen.

I am gathering you have some experience, and Im looking to be a sponge of information.

Thanks Skooter.

From what Ive read, EFI live is one of the easier programs to use. But I got scared of doing it myself, and started researching who to have do it.

When I get a second, Ill post links to what Ive looked at, and you can see the info Ive gathered on it.

Fack - cheapest I found was $750 for the setup with the ability to tune two vehicles.

First thing I"d have to do is find someone to hack it so it wasn't vehicle-based.
I'm all for business making a buck, but if you're buying a product, you shouldn't be limited to the amount of cars you can tune.

How else are they going to make money!!!!?

I have EFI Live and doing it again if I didnt need to tune the Duramax I would go with LS2 edit or HP Tuners, both of those are more newbie user friendly. EFI Live definately takes some getting used to but it does appear to be a more "professional" appearing system. All of them have pretty much the same capabilities and are very powerful programs if you learn to use them to their fullest abilities.

If you want to take a look at EFI Live you can download a trial version, it's the same as teh one you buy, it just doesnt allow you to save files.

There are a few places local to SE Mi that can do tunes. Monkey Wrench Racing in Commerce has done many GM Gen3/4 tunes, don't know if they have the tool to do older GM ECU's. They do have a dyno.

By not butt raping customers that want to do a few cars (more than two). I can understand if you sell it to tuners, you could charge for extra vehicles or foe a yearly license, but (holy shit!) $750 for someone wanting to do their own tune on their vehicle - and limit it to 2 - is ridiculous. Five would be a much nicer number for the consumer.

This is why open ECU rocks - but I don't think there is a GM equivalent.
