Than our vehicles ECM's. I was just on LS1.com and they got all kinds of stuff that was released to their ecm reprogrammer's from GM. (Not exactly a DIY group) but still, why is there so little known about our ecms? Did GM not want us to know the functions possible with our ECM's or am i just misunderstanding something?

-MSD 8.5 mm plug wires
-Gutted cat

It would be nice to have a complete manual for our ecms functions but I don't think it's going to happen. If anybody knows anybody that worked for GM, please get a hold of the engineers .

Where are you reading over there, the stuff I found wasn't all that impressive....

BTW, what guestion have you had about a 165 or 730 that has gone unanswered?..

 

Well, probably nothing impressive, but i was saying, people had to actually do the hard work that GM did for the LS1 owners. Maybe i was mislead. About the only thing i don't get about the 165 is the MAF scalers....Confuses me all to heck, especially when i read posts "I change one value to such and such and car would not idle"

Other then a few leaked documents, GM has been fighting the EPA since 1983 about source codes. They consider it priviledged info and not needed for the home tuner.

Some folks like Lingenfelter, SPL, and a few others seem to get a hand from GM, but just since they all do EPA approved work.

Yes, the MAF stuff is fussy. That's just the way the system is.

BTW, from what I read, I'd stick with the info. here alot faster then there.

 

Leave it to grumpy to get ole' confused and frustrated branz back on track.

Back when our cars came out, EFI tuning and PROM burning didnt exist! In the last 10 years its gotten a following, and has exploded in the last 5 years. The LS1 is the hot new engine so of course all the latest aftermarket stuff will be geared towards it. Our cars are old and there isnt as much interest in them any more, so we get left behind or forgotten. Thats why... I firmly believe if the internet was as popular 10-15 years ago as it is now, our cars would have gotten the attention the LT1's and LS1's get now.

Prom burning and hacing have been around since the first ecms.
Took a long time to figure out the gmese, to figure more out.

Don't hold you breath waiting for a LS1 editor. The flash eeproms are alot harder to work with since they are encrypted, and then need all the normal hacing.

While some firms are selling some programing stuff, so far I haven't heard of any of it actually working.

The 8D and 6E are the money makers for the folks selling editors. Few folks also tear into their cars that are under warranty to tinker with them.

Folks like Lingenfelter and SLP which do enhanced (legal) products are the only ones getting the prime info., from GM.

 

Well, i guess one day i'll get to prom tune the ole 98 z sitting out in the driveway waiting for me to drive it. (i don't feel comfortable in it) Would be a new venture as is the 6E, then again, i always like to just dive in...no matter what the waters hold beneith the surface. Then again, i'm sure you've heard that one before. Thanks for being patient with people like myself, i for one really appreciate it as i'm sure it can get frustrating.

Might investigate using say a MY95 PCM that is hac'd.
If the wiring and connectors are the same, might be an alternative.
