Hi everyone, been lurking on here for some time, and have read all this thread as there's a lot of information that can apply to other Megasquirt/microsquirt applications other than Mustang. While I'm not a necessarily a Mustang guy my latest build does involve a Mustang drivetrain. Years ago I had purchased a totaled1989 Mustang GT for another project. I pulled the drivetrain for the project, but things changed and I sold that one, but the engine and transmission languished in the corner of the shop for years. So I'd wanted an MGB V8 ever since the first one I saw probably in 1980 or so. So I finally decided to build one. The end game will be fuel injection and distributorless ignition. But in an effort to contain costs on the project and hopefully get it running a little sooner I decided to use a Holley carb that I had on the shelf along with an intake I picked up cheap. For ignition I decided to use the stock TFI distributor, since I already had it, and install a Microsquirt to control the advance curve along with electric fan programing and such, and it would be in place for the FI conversion at a later date. So I got the engine running a week ago, but it not very well at first, and here on Stangnet I found a setting that was recommended that was different from what the Microsquirt documentation recommends. I made the change and the car runs good now, pretty sure it was in this thread or one that Steve had responded to, Thanks! But I do still have one problem. When I made up the wiring harness I put in a connector to make it possible to disconnect SPOUT, well, I guess because it seemed like a good idea at the time. Anyway when I go to start the car it won't start with the SPOUT connected, at least not on a cold start and rarely will restart if you stall it. After you warm it up and shut if off with the switch it seems to start OK, at least most of the time. So if I disconnect the SPOUT the engine starts about as fast as any I've seen, well under a second of cranking. Once it starts reconnect the SPOUT and it runs great, timing follows the table and everything is fine. And for the most part it will restart if you shut the engine off with the switch, at least until it's time for another cold start. I can't help but think this is something simple, but I have searched the web for an answer and can't seem to find anything. Any thoughts?
And thanks for all the information you've shared, it's greatly appreciated!!
