I have a DIYPNP setup that I assembled with the help of the tutorials at the DIYPNP website. They provide a startup map for a custom fiat (88 2.3T) install and an illustration detailing the jumper connection. I successfully loaded their startup map with the laptop but have not plugged the DIYPNP into the car out of fear that I may have improper jumper configuration. I am installing the DIYPNP on a car that has 84 turbocoupe wiring and is completely stock and runs great with the EEC/IV. I was wondering if anyone knows if the jumper config and startup map will need to be different for the 84 harness since it is wired slightly different than the 88? Also does anyone have a startup map that has ignition timing that is nearly identical to the EEC/IV? I noticed the startup map they provide is a much older firmware (3.03) than the (3.21) MS extra release. If I get this running on MS then I will be set to start modding the engine for power (big injectors, exhaust, porting, etc...).

Bump also was interested in this.

DIY does a good job of supporting their ecu so they should be your primary source for this type of info.
As for the timing map, there is no way to directly correlate the stock ecu's "load vs rpm" timing map to a standard KPA (boost/vac) vs rpm timing map used in every other ecu. Furthermore, I'm not sure why you'd want a "stock" timing curve anyway since it's only marginal for a stock 2.3T and certainly far from optimal for a modified setup. You could always use the timing map we have posted in the sticky thread on this forum.

I think he really wants just a base tune on the most current firmware that safe. About the harness... www.rothfam.com/svo/reference/I forget which PDF file has the harness Pin outs. Just check yours verse the one the DIY is set up for and swap the pins.

DIY should have no problem providing a tune.

Thanks, I am banned on DIY for some reason and never even got to post anything. I signed up and was able to browse but then it logged me out and does not recognize my login and apparently my email is blocked. I am on my own on this and need a base firmware and do not know what resistor to put in the S1 location.
Stinger: Thanks for the advice on getting a timing map from the sticky I will look it up. Also I wish to get a copy of the most recent stable firmware to start with. The loader for the 3.03 firmware DIY provides does not have a 64bit compatible loader although I did extract the .bat loader from another newer firmware. I was hoping someone else had attempted to install the DIYPNP on an 84 turbocoupe and could offer a working start map and jumper reference.

Have you tried emailing DIY?

I just now sent them a message. Thanks, I will post back when I get it all figured out.

Well, did not get an email back yet so I finally decided to take a chance and plugged the module into the wiring harness and it started right up! It runs super rich because the coolant temp sensor reads 20 degrees. So I guess the answer is to take their base tune and swap the download_MS2_firmware.bat file with a newer file from their 3.3 release in order to load the firmware. I was so worried the wiring difference between 84 and 88 would be enough to fry the unit. Apparently the jumpers listed for that fiat topolino project apply to 84 turbocoupe cars too. Now I must mod the wiring harness to support the second air temp sensor that is located on 88 cars. I already added the sensor to the intake manifold.
I hope this can help out other people who are doing the same install. Thanks for the advice from Stinger and Warwickben!

Your coolant temp problem may just be that the tune isn't yet calibrated for the Ford sensor.

If you upgraded the firmware, it is calibrated for the GM sensors. Recal coolant and MAT.
