Re: 1986 Ford Mustang 5.0 EFI swap

This trigger wheel knows which cylinder is which and they say it's inside the distributor? Would it be CAM sensor than? Good call. Thanks for catching that! I'll change that now. Are you ready to crank it without fuel to see if you read cranking RPM? Unfortunately this is for my friend's project an...

Re: 1986 Ford Mustang 5.0 EFI swap

Finally got the tune uploaded. This is again my first stab at Rusefi and Tunerstudio so hopefully it's decent. The pin mapping is correct, and I'm hoping the settings are as well, though I know the ford idle solenoid is natorious on tunerstudio to be tricky so hopefully I can iron that out later. Ma...

Hm. You're right. Looks pretty straight forward so far.

Hello all. I am finishing up a plug and play for my buddy's 86 foxbody mustang 5.0. I am fairly new to rusefi and would like direction on how to add a trigger for this vehicle.

On older vehicles you use the HS outputs after you run out of LS outputs so it's now worth the bother to rewire. That's the only use I've ever found for them. I guess new vehicles have stuff that is HS from the factory
Good to know! Glad I caught it though. I pushed the changes to the repo.

Re: 1986 Ford Mustang 5.0 EFI swap

Well, I'm glad I checked back through things. I actually had the IAC wired to a high side output. I didn't even think that it was a low-side! I ended up re-checking all the outputs and turns out the check engine light was also a low-side switch as well. On that note, what would normally use high-sid...

Re: 1986 Ford Mustang 5.0 EFI swap

Nope, it's not 1k, it really is a single ohm. It exists to add ESR to C1006, as they together form a snubber to damp out ringing between the supply power wiring (which is an inductor!), L2002, and C1001. The switching power supply means not only that there can be voltage ripple on the output, but a...

Re: 1986 Ford Mustang 5.0 EFI swap

The point of the main relay is so that you don't have to have all the injector/idle valve/ignition/electronic throttle/etc current flowing through the ignition switch, and the ECU can turn it off if something goes wrong, killing the engine. Ok! That makes sense. For my personal setup I will definit...

Re: 1986 Ford Mustang 5.0 EFI swap

You already have a main relay, it's labeled "EEC Power Relay" on the wiring diagram. The ECU doesn't need constant 12v - just switched 12v from the ignition switch (this one is pretty low power - maybe 100mA draw), and the 12V_MR pin, which is for higher power stuff on the ECU, to be powe...

Re: 1986 Ford Mustang 5.0 EFI swap

Also, do you really want the main 12v and 12v MR both connected together? If the ECU has a pin switched by the main relay, you want that one connected to 12V_MR, and the ignition switch connected to the other. Hmm. I saw the stuff about the main relay in the wiki but wasn't sure if it was needed. T...
