PCM Tuning on Ecotec

[damchap]

I am doing an engine swap. Putting a 2003 Ecotec, tranny, computer into my 1995 Cavalier.

I am turbocharing it as well as doing other mods and it would be great to be able to tune this car.

This has been brought to everyones attention. The need for 4 cyl GM tuning software is incredible. But it will take time since the V8 and V6 software will come first.
I do post updates as I get them here:

http://www.j-body.org/forums/list.php?f=2

This is a huge market and I think as soon as possible the software will become available..

[Chris@HPTuners]

yep, we hear ya. The j-body.org thread is unbeleivable.

FWIW, i have had a very preliminary look into how much work it will be to get basic reading/writing functionality - at this stage it looks doable (there are quite a few differences even in the basic comms routines).

Until we develop the base level capability it is very hard to give any possible release dates of a complete flash/editor/scanner package. We will keep you informed as we make progress.

Wow just wow..

All kinds of useless banter in that thread.

One looker for the PCM would be at the Saturn L series PCM. It's MAF and uses a WB02 (Ironically the same one used in the new Te controller). It is supposed to be the same for both the V6 and ECOTEC Saturn, but possibly not the same as the rest of the ECOTEC motors.

Also it would be nice if it also worked for the ION and especially the RedLine, but they are CAN based PCM's and unique again to other ECOTEC vehicles.

BUT if you want pin outs for them hit me up I have all but the RedLine.. not that I couldn't get a photocopy of it from the local Dealer buddy friend of mine..

Is there any news on the Ecotec version of HP Tuners? I am starting a turbo project on a 2003 Sunfire and need to know if this is going to be available soon or if I need to go a different route like a DFI or FAST stand alone unit.

I have seen your LS1 product and it looks great so I was hoping for this product on the Ecotec PCM. Much cheaper and easier than the stand alone route.

Thanks.

no further news at this stage.

[Chris@HPTuners]

something before Christmas is unlikely :-[

We haven't forgotten about you guys, we successfully verified a few technical things last week and are moving forward. We have a lot on the "to-do" list at the moment... :-/

has anyone decided who will be the beta testors for the j-bodies?
i'm just about ready to blow engine #2

[03EcoFire]

yes there is soo many people on j-body.org that ask about software for our cars. i'm dying to get software for my Ecotec. any ideas when it will be released, if any is to be released. i had my new cams thrown in and now my car hates me for it. i need something to take care of this for me and hopefully you guys can comeout with some software to do it for me and the rest of us at JBO.

Is there any update on the status of this?

[CETICARS]

I just put a Ecotec in the back of my stretched Fiero , I am doing the wiring now with a 2003 caviler harness & ECU , i am interested in the software to tune this engine the people with the marine stand a lone system are claiming 170hp with a stock engine an a larger diameter exhaust system can anyone here tell me about the theif light that is in the gauge cluster I am trying to bypass it, is it a voltage reading back to the ECU

[ledfootsteve]

Ok, its been a couple of months now since I visited the forum. (I voted my vin # for initial application) Also where did all the posts about the ecotec go ??? (there used to be a ton of posts in that thread)I remember reading in august that It would probably be ready for beta testing by now. So how far have you guys come? I noticed that over 1130 people have read the current post on ecotecs so I can't believe there is not a market for this application. Have you changed your mind about persuing product developement?

Am hoping HP Tuners will come out with a tuner package for the L61 Ecotec engine used on 2003 Chevy Cavaliers. I've been reading GM Sport Compact book. They claim you can use a 150 HP nitrous setup if you have forged rods/forged pistons (250HP-400HP section), but nowhere in the book does it tell you how to retard the timing. (The NOS website says that anything over a 50HP jet selection requires higher octane gas and ignition retard, especially if you use the NOSzle setup. The NOS website also recommends not going more than 50% of the rated horsepower output of the stock engine when upgrading to a NOS setup). How GM can claim and/or say this I believe is very misleading. I have Eagle Rods and Wiseco Pistons in my engine, with a ported/polished cylinder head, RSM Crank Pulley, NOS Fogger Nozzle setup (28NOS/16Fuel Jets). RKSport Intake, Iridium Spark Plugs, 255 Liter/hour fuel pump w/8AWG wiring, LT1 Adjustable fuel pressure regulator, 6AN supply/return fuel lines, JAZ fuel filter, etc). All of my attempts at researching current electronic means of retarding the timing on my engine using aftermarket boxes (Greddy, etc.) to see if there is anything available has proven futile. For the suspension, I'm using 215/45ZR17 Yokohama AVSES 100 tires, Kazera 17x7 wheels, Eibach Springs, KYB Gas Shocks, RK Sport Front/Rear Strut Tower braces, RK Sport Subframe brace, Prothane Front Lower Control Arm bushings, Prothane Urethane Transmission Mounts, Eibach Front/Rear Sway bar kit, with SSBC Big Brakes Front/Rear w/Stainless Steel Teflon Brake lines and DOT5 brake fluid. My nitrous setup includes Air/Fuel ratio gauge, Boost/Vacuum gauge, Air Intake Temp gauge and EGT gauge.
