Hello all. We are performing a PCM upgrade for a customer from a 1996 black box Vortec PCM to a 2002 "0411" OS 12212156. Mainly to accommodate tire/gear changes, etc. Anywho. The project truck is...
Welcome.
You will need an .xdf(OS Specific) and a raw .bin to make use of TunerPro. If you do not have both, you will need to acquire them along with any necesary hardware to flash the modified...
That tool does look awfully familiar...one if the gents down under...
If you're going to go thru the effort of using a 411 for the trans, sell the Fitech and just use the 411 for everything, fuel, spark, trans. I will ultimately be more reliable and less frustrating....
Ok, let's discuss your situation. You are using the 7427 pcm to run the engine side correct? And you suspect a wiring issue which is preventing you from using the 7427 to run the 4L80, correct? What...
As far as wave shaping, couldn't it be done with an RC filter. All its really doing is creating a non-digital type signal correct? a little slope on either side of rising/falling edge? Or am I...
Xnke,
just how soon is "shortly:? :-)

Evilstuie,
The pcm will be performing circuit test to check for the presence of the TCC PWM solenoid. a work around to this would be to disable tcc pwm flags, that will keep the pcm from worrying...
If you are running MAF, make sure it isnt contaiminated. Trans gets primary load information from MAF, if that data is skewed, youre screwed.
Welcome to the forum. Are you using the factory ecm?

Hopefully the 2732's are new and blank otherwise you shall need to erase them. The PROMs are not interchangeable between the 288 and 747 unfortunately as you discovered.
FYI, there is a FITech owners Facebook group, which is worlds above Fitechs actual tech support if you are interested. This particular group is NOT admin'd by Fitech, but actual owners and tuners.

Most of what you want can be done with software, and you wouldnt need delteq hardware(which is likely supported by accompanying firmware). The coil driver hardware is easy, the software, on multiple...
Double check all grounds. Also, jump diagnostic pins or hook up laptop/tunerpro to gather any codes that may be stored. Could also be valves adjusted a tad too tight.

Sounds like its time to hook up(if not already) the correct pcm, a vacuum gauge and a timing light and have a look at things. Also check for any vacuum leaks around the intake ports. Spray some brake...
Welcome aboard!
I would look at a similar model vehicle in the bin/wiring diagram section on this site. Venezuelan wiring should be similar to US, minus the emissions components.

I have to agree with Fast355. Ive been in the transmission industry for 20 years, and while those trucks came with the 700R4, it's only because they didn't have another option for an overdrive trans,...
The only time you may experience an issue where EGR is causing a driveability concern would be if the egr valve is being opened by a misplaced vacuum line maybe, if the pintle valve is stuck allowing...
If it were me, I would swap in the 7747 and be done. Maybe a few tweaks here and there to the cal/bin. When swapping ecm/pcm's, always make sure the net resistor matches the engine family, i.e....
Welcome Tom!
In the following link, you can search for your pcm number, and in that section you should find a compilation of bins, xdf,adx for use with TP.

The main benefit to swapping to a 7747 over 8625 is plug-and-play. The 7747 doesnt require any modifcations to the connectors or anything else, its a direct replacement. The 288 has limited support...
It's not so much the connectors themselves as the hardware internal to the pcm as well as the software that runs everything is different.
The '4288 is a direct replacement for the '7747, provided...
To somewhat answer your question, they are different beasts in a few ways. First the 8625 will run the TBI engine just fine, with 2 injectors, blah blah blah. The 5925 is meant to run the CPFI(spider...
Ravex. I would verify all sensor grounds are attached and making good, clean contact with the mating surface. Often times durning engine repair, these grounds get disturbed, broken, etc. I believe...
