I have a 4.9L swap about to get started and all of the scanning tools and software that we have here are OBDI and CANI. We also have a couple of older All Test scanners in the shop that are used on Fiero ECMs but they don't show compatibility with the 93 Cadillac ECM ser no. 16132240. There is probably a way to use the AllTest scan tools but the set up protocols are not listed in the booklets. WINALDL doesn't support it. Scanning is one disadvantage to using these older ECMs but there is surely something available How are you 4.9L owners scanning the 91-93 ECM's?

Dennis I used an AutoXray 5000. It is very user friendly. It is able to scan ODBI and OBDII ECM's. I paid around $100.00 on E Bay for it, carrying case and all the different cables included. I was never able to get software and the compatible cable to work with my 4.9

I cheated and used the 7730 ecm so I could scan and tune it with Tuner Pro.

I use an AutoXRay as well. Think mine is a 6000.

With all due respect I don't believe that using 60's and 70's technology will be superior to late1990's EFI. IMO the EFI's sytems of today with their self adjusting, self compensating mode of operation, and with their onboard diagnostic capabilities, cannot be beat. The Cadillac V8 engine (which is 300 cubic inches) gives 275 ft lbs of torque and most 4.9L Fiero owners report 30 HWY MPG. You just won't get that with a carburetor not to mention the better driving and engine life characteristics provided by EFI.
I guess that I'll check out the older AutoX ray units for scanning. Thks guys.

You can use tunerpro with the caddy ecm and the files are available

On mine I use TunerPro RT to scan and watch real time, and Tunercat to program my chip.

I know what your saying Dennis. Im just an old school kind of guy. Ill take 18 mpg to replace it with a car that I can fix at the side of the road with a few simple hand tools at least enough to get home. Im an old diehard that says old bulletproof tech is more reliable. Look at what Cuban car owners do...they can fix anything and make it run again with parts from anywhere. Ive had some of those diagnostic testers and they never told me anything that was wrong with anything. Even dealerships with $100,000 machines couldnt figure out was was wrong with some of my cars. 3 Mercedes dealers and a few European repair shops couldnt find a miss in my Mercedes to the cost of prob $4000-$5000. It took a backyard mechanic 2 minutes with a dinosaur occilliscope to find a crossed coil wire connection...and fix it. Chrysler purged fuel inj system, replaced, drive by wire thottle, replaced pedal assemblies, diagnosed valve operation etc for hours trying to find a die problem before they found a broken '0' ring seal in the gas tank recovery system by chance. None of their equipment showed it. They found it by trial and error in the end. All that fancy equipment was worthless. With todays cars, if you have a problem, your stranded period. I cant hardly wait to see what happens with the Nascar cars switch over to FI next season. I predict a multitude of problems and complaints right out of the gate.

I completely understand the point that if you keep it simple, problems will be easier and less costly to fix. Thats why on all of the recent swaps that I have done, we operate with only 8 sensors. MPEFI is usually very reliable but when something goes wrong it can be a ***** to diagnose. I guess that I won't convince you that EFI is more advantageous than a carbureted engine but like the phone booth, typewriter, tape recorder and B&W TV nothing is forever, Changing with the times and accepting moderrn technology is where I chose to be and in case of a breakdown I have AAA gold.

Is that the early version of the super expensive Tech 2?

I used an AutoXray 5000. Works great and easy to use.

Ill agree there are advantages to both FI and carbs. With FI you have no choke and generally easier to start under all conditions, you do get better gas mileage. I have no problem hitting the gas a few times to start my Coronet 4 bbl. It will always start even below 0*. FI will never give you the sound of a big v8 4bbl opening at wot. My new Mustang Bullet, even with cat back exhaust kit and performance cams sounds like a whimpy ricer. I heard a guy at a show last weekend reving his new Corvette with factory exhaust cutouts and it sounded like a bigger engined Honda. I couldnt help but smile at it.

I use an auto-x-ray scanner at the moment. During Jtsordel's swap though we will be setting up with tunerpro and moates.net software/hardware. Tunercat also works.

The definition files for the caddy 2240 PCM are now available from several sources. Software that can read and modify the program is getting to be readily available and can be quite inexpensive. You can also use a flashable 27SF215 chip for quick program changes with no need to UV erase. There are emulators that work now too so you can tune on the go. The 4.9 PCM now has almost full support for the DIY'er and/or proper dyno shop tuning.

I also hear a rumor that, if you know how, code for a knock sensor can be added to further upgrade the capabilities of the PCM. This is a good way to keep the "E" shift transmission and use forced induction.

What?! I wanna know more!

Me too. I'm working on finding out more details. I'll post if I come up with something. Until then I'd love to hear from others that might now.
