I am troubleshooting the TR7 now, I lost the TPS and the tach output. I just checked it on the stim and the Megasquirt checks out, so now I am going to have to test the wiring in the car to find the problem. You just need to be methodical and definitively rule out one thing at a time.

I looked at what you posted. Did you reflash the latest firmware and try again? The Tuner studio sees a usb-serial device as two things, just select the one that is USB device and it'll be fine.

My issues were a broken wire on the TPS and on the tacho circuit I found that it likes to be outside the Megasquirt box to work solid. I just ran a wire out from JS1 to a spare output wire, then connected that to the relay circuit. I find that it won't work taking power and ground from inside MS. Instead run a wire from fused, switched ignition 12v to the relay coil and run a seperate good ground to the emitter leg of the transistor to have it work the best.

If you keep having issues you can send me your MS and stim and I can check it out on the bench. I bought some spare parts last week, so if you and Travis need me to build the tacho circuits for you I can do that. I'd need $25 each for them. You will just need to solder one jumper wire inside MS to the output wire you want to use.

I've only dealt with an old fast efi setup, but from what little I've read on both setups, they operate very similarly. On the fast efi, the only thing the computer needed was a pip or crank trigger signal and tps to initiate a start procedure.

Wish i could help more. I hate wiring and electronic things.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

Sometimes I find that if I back away for a bit and work on other things it helps a lot.  I made the biggest mistake of shelving my Bird for about nine years because I got so pissed at it.  I forgot how much I enjoy the car and letting it sit that long cost me more $$$ in the long run as cars are not meant to sit.

Step back, take some time, and then get back after it.  One thing that I have found that helps me is writing things down as I go so I have reference points.  I think Chuck is really good at this as he refers to his notes a lot in some threads so my guess is he has a few note books with all kinds of info.

Anyhow, stick with it and when it all comes together you will be very happy you did.

I know how you feel. My bird has been sitting for over a year while I get the MS going. It's all wired up but I had to clean up some noise on the crank sensor signal and I wasn't capable of doing it. Had to have some friends come over with O-scopes to get it done. Then I burned up the coil pack.. Doh. May get out there today and fiddle with it, see if it will fire up.  Good luck!

Looks like I need to re-solder some grounds for the Quadspark and then there is a chance.  :)

I guess there is always a chance. After a solid month of frustrating the s@#& out of myself it looks like a bad daughter card. Still under warranty. A month of it. Hope that fixes it. Mailing it back tomorrow.
