I know from reading on here that most are tuning Ford EEC's. I own a Ford but also own a 95 Chevy Blazer, a 2003 Kia Sedona, and a 2000 Chrysler PT Cruiser.

My question is it possible to tune all of these with the QH or do you have to get different hardware and software to tune them?

The Ford is the only one that will have mods done to it. The others will be staying stock but desire the best HP, performance, and fuel economy.

Are the tuning experts here mostly for Fords only or does this site also support and encourage learning different makes?

Thanks

I revisited the Moates site and answered my own question. Yes the QH can be used with Gm products. Im a little confussed about how to tune a GM because there is much less information out there on them than there is for the Fords.

However it does not seem to support Chrysler.

Any other information or advice would be appreciated on what would be the best route for tunning all my current vehicles.

Thanks to all

Also from what I can find is that my 1995 Trailblazer was a transitional year. The 1995 1/2 is when they went to the Gen II 4.3 Vortec. Im pretty sure that is what I have since it looks different than a friends 1992 S-10 4.3.

Can anyone shed some light on this?

Barring retrofitting a non-Ford vehicle with an EEC engine controller, I'm not sure how on earth you'd ever make the QH work on one. Do tell?

You are correct. I said QH but meant that Moates offers hardware and software that will work with my Trailblazer.

It seems that the hardware would be the RoadRunner and software would be CATS or EFILive.

Sorry for the confussion.

Also I found out that mine Trailblazer does not have the 96 Engine but the same as 86-95.

Here is what the Moates site says about it

Basics
When we talk about “OBD1″ GM vehicles, we mean vehicles made from (approximately) 1986 to 1995. These cars used several different types of engine controller – some have one injector for each cylinder (Tuned Port Injection, or TPI along with the LTx motors) while some have fewer injectors that are placed near the throttle body (Throttle Body Injection, or TBI) instead. All the vehicles of this generation speak the ALDL protocol for logging/vehicle communication.

For purposes of this guide, “ECM” means Engine Control Module, Powertrain Control Module (PCM), Engine Computer Module (ECM) – terms will be used interchangeably to mean the same thing.

Hardware for OBD1 GM
Overview
94-95 model years are oddballs. Many of these ECMs support being reflashed over the ALDL interface (e.g. LT1) using TunerCATS. Some (like the 94-95 TBIs) use a G1 adapter. Many Grand Prix from these years use the G4 adapter. Diesels generally use the G5 adapter.

The process for tuning OBD1 GM products is pretty much the same for all 86-93 model years. First, a “chip adapter” is used to convert whatever the ECM in question needs into a form that accepts a 28 pin EPROM. Some chip adapters require soldering for installation (G2, G2X) but most do not (G1, G3, G4, G5). The same EPROMs can be used for all of our OBD1 GM products (except the switching adapters…) which is usually the 27SF512 – C2.

After a chip adapter has been installed in an ECM, tuning can begin. You can burn chips using a ROM burner such as the BURN1/2. Alternatively, you can either use the Ostrich 2.0 emulator or the emulation facilities of the APU1 to make changes while the vehicle is running.

Logging from the computer is accomplished using either an ALDU1 or the logging facilities of an APU1. For 86-94 vehicles, CABL1 is required to connect the logger and the vehicle. For the 1995 model year, CABL2 is required due to the physically different connector.

Instead of buying the BURN2, Ostrich2 and ALDU1 separately, you can buy the APU1 unit that does the functions of all three pieces in one unit.

i would really love to be able to use be/ea for other vehicles, just for only having to learn one tuning software, which is one of the best IMO. But unfortunately I don't think that's possible since it's really designed for Fords, and not sure it could be adapted to GM. Would be cool if it could be though...

In case you missed your other post:

I currently drive a 95 Chevy Blazer and my wife drives a Chrysler PT Cruiser. I would like to get them all fine tuned and running to the best of the engines stock ability.

Hey Hollis,
Ah, you got the same itch I got. I'm looking into same for my 91 caprice.
You can check out QH info at moates.net It's ford specific to my knowledge. Moates talks about GM stuff too but you need different hardware.

For GM it looks like either tunercat or tunerpro is the way to go.
My understanding, so far, is that tunercat allows you to modifiy more things then tunerpro, but is not as 'friendly' You need to understand better what you are changing. This probably comparable to same like QH vs tweecer.
http://tunercat.com/ They also offer all the hardware you would need.

Tunerpro seems to be just the software
http://tunerpro.net/

DynamicEFI seems to be the closest to QH as you install a module that you can then just program with a laptop. But it seems like it's more targeted to TBI systems, like my caprice has. Not sure what your blazer runs.

I don't know enough about GM's architecture to know how well BE could be adapted. From what I understand, TunerPro works for GMs. So perhaps there's a chance that BE could too! Although I would expect there'd need to be a LOT more changes made to BE to do it well.
