EFIDynoTuning Forum

I’ll see how the bin opens on that def.

One more question on these. For guys just needing stock replacements, You can’t get a reman ecu anymore. Guys are chipping mustang ECUs with the same hardware code and the oem tune to get a working replacement. With Moates going under I guess SCT chips are the only way to keep this up. But is there a way to program the eprom?

These EEC use EFI-MA39C. Would A1C or C9C1 work with that hardware code?

How hard is it to develop a definition a definition for the marine eec-iv? I have a definition for mine with BE that’s locked down as a one off, but it’s not really helpful for others that want to tune these setups.

I guess if you can’t get a new quarterhorse it may not add value

No emissions, no AC, no ps, no o2s. Just a basic speed density setup with 24lb injectors. Full time open loop.

i'll give it whirl! thank you

Perfect! Got a few options now. Thank you

oh sorry.. i didnt realize what you meant. So you're saying the SCT 6601 cable will plug into the F3V2. just get the cable? got it

Is zero the top or bottom from this view?

i just didnt want to spend another $250. I just need two tunes. How do i tell which pin is which?

Does anyone know where i can find the switch assembly for the F3v2? I have all the other components to finish my system, except the switch assembly to switch between tunes.

Or know where i can find a wiring diagram to make one or solder something in? All i found was a writeup of how to do it on the original F3, but is was a different circuit board.

yea best case scenario is that it hooks consistent. Good to know we could do something if needed.
