I did a quick, cursory look at both products, Justin. The TWEECER product is a direct fit, but the website hasn't been updated in years. I'll have to follow up and see if it's still available or supported.

The Speeduino product is still active and they have a USA reseller. It's not expensive, but requires a software product from another company to work. I'll have to see what that S/W costs.

Thanks for those references. They are both potentially relevant.

Cheers,

Tuner Studio works with both Speeduino and Megasquirt and its easy on the wallet.

I'm about to put together a Speeduino, Digikey just delivered the parts. Arduino already has the firmware on it.

Do keep us posted with respect to that project, Tibor.

Another option I'll throw into the mix is a Microsquirt, I'll be using one on my build. It seems very straight forward to wire, it's compact, cheap, lots of support.

If you're just after a basic ECU to run an engine on wasted spark and without needing full sequential fuel injection, traction control, boost by gear, etc. it seems like a good option. It can still do closed loop tuning, flex fuel, proper idle control, etc.

You might try asking at Off Road Warehouse, on Nordahl (assuming that they're still there). You're right, off road stuff is a fairly large market and I'd have to think that people have put Ford V6s in the back of various things. They may have tuners to point you towards.

@Beelzeboss
Thank you. My donor, a 1994 Mustang V6, does come equipped with sequential fuel injection. There are some very Ford-specific products, but they're now out of production. So, just used parts are available. That really puts a buyer "on their own" for tuning and support which could be a huge issue. However, the full Megasquirt product seem to be a possible good fit.


@KB58
Thanks Kurt. It's worth asking them.

Cheers,

It doesn't matter if it came with sequential. It can be batch without issue. Holley has evolved with their efi control products but pricey.

If you have a distributer then the MicroSquirt is a good option. You have to add ignition drivers if you don't have a distributer, it also lacks features like AC circuit. A friend ran one on a Ford 302 with great success.

@MV8
Batch? [SIGH] I'm already out of my element here. Does "batch" mean "all at once" or "all the time" like the old mechanical fuel injection systems used to be?

@FastG
My donor engine does have coils, not a distributor. When you say "AC" do you mean air conditioning or alternating current?

Was your friend's 302 an engine with carburetor and distributor or a fuel injection/electronic (coil) ignition setup? If it was the latter case, that would certainly imply it would run my 3.8L V6.

<EDIT>: The standard Ford system for my 1994 3.8L V6 is the EDIS-6 system. It does have sequential fuel injection standard. I saved all the electronics. What's not clear to me at the moment is if the EDIS-6 controller is a stand alone unit or incorporated into the larger ECU computer itself.

Cheers,

Yes, multiple injectors opening at once at the same rate versus individually in firing order for ecu individual cylinder control (sequential). That's more of an on-the-fly emission tool than a performance tool with an engine in good mechanical condition.

The 3.8 has a cam sensor/pickup in place of the distributor along with a crank sensor to drive the edis. Edis is not standalone. Some have a standalone "limp home" backup, but they rely on ecu input to provide a timing curve to replace centrifugal advance and use other inputs to vary timing based on the load.

By AC I did mean Air Conditioning. It looks like the MegaSquirt does have some EDIS support.

Graham

I am either going to go with speeduino or a megasquirt product for my 2.5l duratec. Likely want to use canbus for some of my instruments

You can use ignition coils that already have a logic level input, like LS1 coils or similar. The Microsquirt can directly drive 4 of those (or 8 in wasted spark) with just 2 resistors added. That's how I'm going to run my V8.
