The MegaSquirt Project has experienced explosive growth other the years, with hundreds of new MS installations occurring every week - a phenomenal success! MegaSquirt has been successfully used in all aspects of Internal Combustion engine applications including R&D, Industry, Race, and Research. The MS project has transformed itself from a simple R&D project into a full-featured mature engine control system. To reflect this the support structure has also changed to meet the needs of MegaSquirt Users.
Moving forward, the R&D forums for MegaSquirt project are in a read-only mode - no new forum posts are accepted.
However the forums will remain available for view, they still contain a wealth of information on how MegaSquirt works, how it is installed and used. Feel free to search the forums for information, facts, and overview.While the R&D forum traffic has slowed in recent years, this is not at all a reflection of Megasquirt users, which continue to grow year after year. What has changed is that the method of MegaSquirt support today has rapidly moved to Facebook, this is where the vast majority of interaction is happening now. For those not on Facebook the msextra forums is another place for product support. Finally, for product selection assistance, all of the MegaSquirt vendors are there to help you select a system, along with all of the required pieces to make it complete.
This is the place to ask general MegaSquirt® questions if you are just getting started.

Forum rules Read the manual to see if your question is answered there before posting. Many users will not reply if the answer is already available in the manual.
If your question is about troubleshooting, configuration, or tuning, you MUST include your processor type (MS-I or MS-II) and code version in your post. If your question is about PCB assembly or modifications, you must also include the main board version number (1.01, 2.2 or 3.0).
I am interested in building an MS-II for my 89 mustang. It's running a 2.3t from an 88 Turbo Coupe. I see where there is a cable to allow the 5.0 guys to simply plug into their stock harness. Is it possible for this cable to be re-pinned for the 2.3t?
Take a look at DIYAutoTune's DIYBOB units; there is one for the Ford 60-pin EEC-IV connector. You have to assemble it yourself using a DB37 pigtail harness, but you were planning on re-pinning, which is probably harder than soldering a whole whack of wires!
Thank you, I think your right the DIYBOB might be the better option. The Adapter Harness says it works on the ford 2.3T but also said in the description that they didn't recommend using it on low impedance injectors. Rules me out, DIYBOB it is then.
You can use the cable with low impedance injectors if you add injector resistors. The problem is the stock wiring grounds are pretty marginal and do not take nicely to PWM current limiting, regardless of what adapter you are using.
Would I still need the injector resistors if I used the DIYBOB unit instead? Really trying to keep the wiring stock so I can toss the old LA3 ecu back in if I ever decide to sell.
Read Matt's post again - the issue is effective grounding through the harness, not the connector. Upgrading the grounds of the stock harness (extra wires in parallel) shouldn't be that hard.
