Does anyone that has done this conversion used a scan tool software with it? I thought I had read in this post that you could use FreeScan. I am trying to use it with my 3.4(DIS)new build. Unable to start engine yet. Software (selected 3.1 engine)on the sensor scan page has a line that is called crank postions =0 is this saying I am not getting feedback from my crankcase sensor? Is there any other software to use?
Mike
P.S. I think I may have flooded it and is the cause for it not starting will know more tomorrow. I have spark, fuel at the shrader valve (psi? will check as well tomorrow) and i have a pulse at the injector connector
Just would like to understand the software a little better. |

What interface cable are you using? The 7730 ECM communicates using 8192 baud. If you bought an interface cable for the stock Fiero ECM, it might be one of those versions that only works with 160 baud communications; and that will NOT work with the 7730 ECM. www.aldlcable.com sells an interface cable that will work with the 7730 ECM or you can build your own using instructions I have posted on my website here: http://dtcc.cz28.com/eprom/DIY.htm
FreeScan should work fine with the 7730 ECM. Make sure it is configured to read a "GM410B" vehicle. If that doesn't work, try "GM 1992 Pontiac 3.2" config. If you can't get FreeScan to work, try TunerPro RT's scanner. This tuning software suite is quite inexpensive to buy but does come with a built-in scanner. You can get TunerPro RT here: http://tunerpro.markmansur.com/

I am using one custom built by Dodgerunner that operates on the faster baud rate. I know it is working, When In turn on the key I get a status update with header info and coolant temp, map, O2, all update. But cranksensors =0 even when cranking the engine no rpm indicator either might be too slow to record.

You may not get a valid RPM signal on the scanner just by cranking the engine. I have seen this occur before (don't know if that is what is going on in your case). But when the engine starts and runs, then you should see valid RPM data.

I have 3 of these 7730 ECMs WITH Memcals and connectors. Asking 50 each + shipping.
These are salvage yard pulls from V6 cars. All cars had damaged engines/transmissions or body damage consistent with wrecks.
Need these gone ASAP.

I now have wiring instructions available for wiring up the 7730 ECM -AND- DIS (distributorless ignition system) to the Fiero 2.8 wiring harness. You can download them here: http://www.gmtuners.com/fil...o_V6_to_7730_DIS.pdf
You can download the 7730 wiring instructions for distributor applications here (so you don't have to go back to earlier pages in this thread to find the link): http://www.gmtuners.com/files/Fiero2.8_to_7730.pdf

awesome - thanks!
I will go and look, and dbl check my work - I am wrapping up my wiring harness right now, and getting ready to re-install the cradle. also fixed my auto 2 manual swap wiring while I was at it.
anyways - the Q:
is there a way to know what "codemask" my ECM has? (not even sure what "codemask" is...)

"Code Mask" is another name for OS, or Operating System. Basically the OS is to a GM ECM as Windows XP or Vista is to your PC. The OS in the ECM runs the engine and controls the various outputs based on the information stored in the calibration, or programming.
The only way to determine what code mask/programming your ECM has is by deciphering the broadcast code (BCC) that labels the stock chip. Examples of where to find the BCC can be seen here: http://www.gmtuners.com/eprom/BCC.jpg
Locate yours and email me with it and I will see if I can find out what it is.
