Mike, I have a Holley Commander 950 for my ProCharged LT1.

I'm putting a 5.3 in a 88 chevy and lookin for a ECM to run. Been lookin at the Big Stuff 3 cause it can control the trans to but it cost alot. I was hopin somebody would come out with one that wasnt so race based. The factory ECM works great but to tune it u have to buy some software like HP tuners, EFI live, etc to so it adds up to.

Hey Mike,

I run an XFI on the old school small block 427 and run a gm gen 3/4(speartech) on the new LS7.

Holley HP or Dominator EFI. Either ECU can do an LSx and the Dominator does LSx and 4L60/80e trans aswell. Touch screen is nice replacement for the laptop Due out in a month or two.

I've run/tuned everything from basic SDS systems years ago to Motec. They all have merits.

looking for a ECM. Heres a new idea. something reasonably priced would be different.

Pantera 882 this time around. Not satisfied with Gen VII or XFI on other installs I've done and I prefer the Pantera over BS3.

Holley's new Dominator system looks intriguing on paper, I can't wait to play around with one first hand.

running a ecu out of a 2004 surburban fly by wire.witch by the way I hate. if your going to design a new one please make somthing compatible with cruize control.good luck with whatever your after.:thumbsup:

Here is what I posted on PT.com

I would say it really depends on the engine and trans combo.

For the LS1 and LS6 cars with a cable, a 2001-2002 Camaro works for me.

For LS1 and LS6 DBW, the a 2001-2004 Corvette.

For the later LS2, LS3 or LS7 DBW with a 4L60E, a 2006 GTO.

For a later LS2, LS3 or LS7 DBW with a manual, a 2007 Z06 Corvette for an NA car and for a FI car a 2009 LS3 Corvette.

For an LS2, LS3 or LS7 and a 6L80E it would be a 2008 G8 or a 2010 Camaro SS.

I personally try to keep away from the E67 and E40 ECM's.

A lot of different possiblities for sure.

Of course as far as aftermarket I prefer the FAST XFI and BS3. Looking at the Pantera to get a comparison as I have yet to use it and I should have one of the new Holley setups to work through before long. Actually trying to get to BG for a look through.

Hope that helps.

We are not building a new ecm. We are working on components that integrate with them. Ecm programming varies between makes so we are trying to find the most common to start with, and work from there

Are the 99-00 camaro ecms different from 01-02? I thought the 98 was the outlier of the group.
