"Note that if you are using a PWM Idle valve, such as those used in some Ford products, the standard transistor on a V3 main board is not sufficient to power the valve directly (on a V3.57 SMD main board, or a MicroSquirt, the FIlde transistor *IS* sufficient to drive a PWM idle valve without modifications)." So I can run the 3.57 version board? I thought it wouldn't run right with odd-fire? Does it matter if i lengthen the hose to move it away from the fuel rail/will it affect idle?
I'll take you up on the coolant adapter idea. thanks!

Don't go with the 3.57 board. Two of us got the 3.57 board and we spent hours trying to get it to work properly. We we borrowed a 3.0 box and installed it, the Delorean ran great. I still have the 3.57 board but Matt at DIYAutotune had to modify it for it to work and even now it's not 100%. I have to open it up and make another change inside. The other owner had his box switched out from 3.57 to 3.0 and now the car is running fine. Spittybug can go into more detals on why the 3.57 didn't work.

Is it just ignition control when you have trouble with the 3.57? I am running fuel only and have zero problems with mine.

[Delorean Industries]

Yes. There are work around solutions and I believe it can be/is addressed on all current boards.

You are correct. When we first fired up my car on fuel only, the car ran like a champ even though it had not been started for two months. When we turned on spark we had issues.

To let everyone know what issues we had with the 3.57 box and what was done, here is an email from Matt with DYIAutoTune:

"The main difference between the V3.0 and V3.57 is the input impedance -
it's higher on the V3.0. I have shipped this one with three
resistor-on-a-wire jumpers to let you change the impedance. The one I
think will be the best bet is a 15K with green leads, and I have put
that in your ECU. There is also a red 10K and a blue 20K - use the red
one if it won't sync at low RPM, or the blue if it's having high RPM
problems but low RPM is fine."

This was the change he made in my box. When I took my car in to the dyno shop, there was sync loss (?) at very high RPM so I plan to swap the green lead with the blue one to see if that makes a difference.

Keep me in the loop on this. Is there any benefit to having the 3.57 over the 3.0 for what I am doing in your opinion?

What do you all think of this? Any other major specific parts I am missing or that I have incorrectly listed?

Are you able to convert to EFI before installing the Turbo. If so I would recommend that in order to get it running first.
