What programs are you guys using?

I use a Powrtuner (that's actually how it's spelled with the missing "e").  It works with the GM 3800 series II (97-03) V6, some of the GM 3400's and most of the newer series III 3800 (04+) V6's.  Awesome hardware/software setup.

SCT XCalibrator 2 and Advantage II (Dealer) software on the Explorer and an SCT LiveWire on the Focus.

Ran 15% Ethanol (E85+87 Gas) on the stock PCM with a 12% error (LTFT's), next tank is 20% just to see what the PCM can handle stock (and do some fuel system cleaning!).  Then I'll push it until the PCM can't adjust (CEL).  Then it is tuning time.  We can't get E85 in Seattle, so I have to pick up 20 gallons a trip when I go to Portland OR for business.  Looks like fun!

It's not my car, but we're playing with some aftermarket stuff. I ran E85 fine on a stock computer with larger factory injectors. Tuning would be handy, but I can't get into these ECU's. So...on to replacements and we've come across plenty! Additional injectors work fine. If you can adjust gain and on-time out of a simple injector controller like an SDS or Megasquirt, you can get all the extra fuel you need and still maintain flex fuel capability by turning them down. Link, Element Hydra, Motec, SDS, UTEC, Electromotive...the list goes on with what already works. Even my stock unit works great, but darnit I can't get inside it LOL.

  I am using LS1-Edit on my 2000 5.3L Silverado.

 

It looks like I have to step up my fuel injectors to 43#

 

They are running at 100%+ with 50% Ethanol.

 

Someone wrote me a while ago about his (98?) 454 powered Suburban. I get letters occasionally from people who are having a hard time finding re-write software for an odd ecu range of vehicle and this was one of them. Do you know what might work on that truck? I dug high and low for what he needed and it's usually a matter of redirecting them to a supported piece of hardware for their vehicle. I found nothing for his, though. My ECU is the same way, falling into that same crack of no ECU support for a 2 year span.

Okay I have finally done the swap to E85, if anybody is thinking about doing the swap and you have E85 in your area I can fully vouch and recommend that the performance gains are very noticeable.

 

I ran the car down to 18 miles to empty as I didn't trust driving any more without filling up, connected my DiabloSport Predator and uploaded the E85 tune where after I filled up 1 gallon (just being cautious), car started right away and I let her idle for a minute a then took her for a slow drive for a half mile or so, after that I opened her up and all was well  Then went back to the gas station and filled her up for under $40.

 

I have more spark advance as well because of the slower burning fuel there is about 4-6 degrees more timing in the middle (part throttle) and about 3-3.5 degrees more @ wide open.

 

I will be pulling the plugs sometime soon, clean them and reinstall and then read them after a tank of E85 has gone through the motor.
