Ok so i'm looking in to getting EFI live and while looking through the forum i was getting confused, I have an 2003 GMC sierra with a 5.3, so am i a gen 3? what ecm do i have? Please help it all make sence
Ok so i just looked at the EFI live site and i did see that I fall into the gen 3. Is there any thing you guys an tell me that might help like which ecm i might have. I see number thrown around like T43 is the the ECM, TCM or PCM #'s? The EFI live is something that i really want to get in to, I just want to know a little more before i buy it.
welcome
yeah I'm pretty sure you have a Gen III, not sure what PCM exactally, someone running a simmilar truck might be able to help. all I can say about EFIlive is that its the best thing to happen to my truck, hands down. if you get it you won't regret it for a second. and everyone around here is very knowledgable and helpful, which makes learning to tune so much easier and more enjoyable.

Thank you! I'm really looking forward to start tuning. Any info or tips on tuning my truck would be great! The only bods i have right now is a K&N and the vet servo swap.
Get a Wideband for Auto VE and MAF tuning , and read , read , read , tuning is not hard just lots to consider .
To me EFILive was easy to learn versus the competitor , but that was me .
Download the Demo and have a look at EFILive : http://www.efilive.com/index.php?opt...=48&Itemid=133 and then read the Tutorials : http://www.efilive.com/index.php?opt...130&Itemid=134.
2005 1500 HD , Custom OS3 SD tune .
2006 Trailblazer
Dinosaurs and Plants gave their lives so that we may drive , long live fossil fuel .
what do i need for the wideband?
You need a Wide Band AFR controller,
one that has a serial and/or analog output.
Most have a linear analog output stay away from the ones that don't
to make things easier.
