rags Posted November 14, 2008 Share Posted November 14, 2008 Woo hoo! I just got an email from DaleMX that he is sending me the EFILive tuning cable that he used on the LS1 280 he sold me. Now it's time to get started tuning. Is anyone here familiar with EFILive? I'm not really afraid to try it but was hoping that I would have one of my Z brothers to lean on if I got stuck. The first thing I have to tune out is a nasty hunt for idle when you come out of the throttle. I'm assuming it's because of all of the upgrades (PRC stage 2 5.3 heads, Thunder Racing 230 cam, FAST manifold, etc, etc, etc), and I'd like to get it somewhat cleaned up before heading for some dyno tuning. Anyone use something besides EFILive? Quote Link to comment Share on other sites More sharing options...
aziza z Posted November 14, 2008 Share Posted November 14, 2008 I have no experience with it but I have heard lots of good things in the ls1 forums. I will eventually get the system after a couple upgrades. Let us know how it goes! Quote Link to comment Share on other sites More sharing options...
ColtGT4g63 Posted November 15, 2008 Share Posted November 15, 2008 I've got no experience with EFIlive either, but I have been using HPtuners for a while now. Its very hard to get use to, but once you've got the hang of it its pretty user friendly and gives you a ton of adjustability. Good luck with the EFI live!

Dudeboy Posted November 15, 2008 Share Posted November 15, 2008 Rags, I forgot to PM you this link about EFI live. You may have saw seen it already-the link was from LS1tech.http://www.holdencrazy.com/EFILive/modifiedTunes.php Good Luck Glenn Quote Link to comment Share on other sites More sharing options...
rags Posted November 16, 2008 Author Share Posted November 16, 2008 Glenn, This is great! There are a few there that I can use as starting points as they list almost all of my mods! Joe Quote Link to comment Share on other sites More sharing options...
rsicard Posted November 16, 2008 Share Posted November 16, 2008 Rags: Suggest getting on EFI Live forum and asking more questions. I am also going to use EFI Live and went to their booth at SEMA this year. Already have PCM, need harness, sensors and actuators. Where were you able to get your harness? Which Mass Air Flow (MAF) sensor are you going to use and did you get the other sensors and actuators with the engine? Please advise. Thanks.

cannonball55 Posted November 24, 2008 Share Posted November 24, 2008 Check Gm part # 19201327 its a kit for the LS series engines. comes with wiring harness, all sensors, the electronic accelerator pedal (complete bolt in pedal), computer, weld in bungs for O2 sensors, Mass air flow meter (with mounting boss) I think I paid 900 for mine thru jegs. Mines for the 480 horse power LS3 but they make one for each motor. Its a complete kit and very well built harness, same as would be in a new vette or whatnot, not some crap built in some guys garage with crimped on ends and electrical tape. Kinda nice that is runs fuel pump and trans shifts also but they are not needed to be hooked up if you don't want to use them.

Bigdeezs Posted November 24, 2008 Share Posted November 24, 2008 good info... looks like a really cool package! http://www.sdpc2000.com/product/19201327/EngineControlerModuleandHarnessLS376480.aspx Quote Link to comment Share on other sites More sharing options...
rags Posted November 25, 2008 Author Share Posted November 25, 2008 Mine harness is a Speartech, http://www.speartech.com/. Pricey but foolproof. All of the sensors came with the engine. Joe Quote Link to comment Share on other sites More sharing options...
