Anyone have experience with making the ecu stand alone for an old school swap? I have a complete Maserati quattroporte and am looking to swap motor and tranny into, you guessed it 69 Firebird. Since I have the complete car, I should have everything I need including all transmission controls. I am looking for information on how to remove smog related equipment and ecu and tcu updates. Any ideas?

In my GT there is a car ecu and a motor ecu, these two are calibrated to only work with each other, I discovered this when I replaced my engine. I would believe this would be true for the QP as well. Good luck!

I think you are gonna find trying to make stuff like this work is actually possible, but just a total nightmare as far getting all the electronics to work without the other modules missing...GM makes some bad ass setups for stuff like this without the hassle or expense in the GM Performance catalog...BTW who the hell puts a 4.7/4.2 liter engine in a 69 Firebird? You need like a built 455 to move that much metal around...No replacement for displacement..lol....Jason

It would be pretty cool if you could pull it off, but you will probably have a 1000 more hrs involved just to get it wired and fired up, compared to a LS swap. But it will be unique so go for it.

I agree with Jason on displacement, but if this is what you want, a Fast system, or Megasquirt II / Megaspark, would be a good option. There is a company that makes ITB systems for Toyota V8's that looks adaptable to the F136 heads. Wicked looking on a Mas. motor. Of course with all that room in the Firebird, forced induction would be killer too...Ed

You still would need a transmission and that is gonna need a TCU and that TCU is gonna need an ABS module to get vehicle speed.. It just goes on and on...Jason

I appreciate your input. I am thinking about the uniqueness of this type of build. Everyone has an LS swap. I'm looking for the reliability and mileage fuel injection would add. The 69 Firebird is a little over 1000 lbs lighter than a QP, so the m139 would make bitchin power and lighten the front end by another 200+lbs. Now you see where this is going? However after talking to some Maserati dealers and mechanics they are telling me the clutch system in the f1 tranny is expensive and unreliable as well as the m139 have very expensive repair issues like timing chain. Though it would make a cool build I've realized The LS 3 or earlier LS6 is way more hp and reliable with a much tighter budget.

Just do a standalone ecu and rewire it, not much different than an LS swap. You could probably use a holley standalone ecu

You may have a heck of a time getting this combination (Engine and F1 Transmission) to work together in another chassis. The problem with getting a standalone ECU system to work (with both engine and transmission) is that the computers require that signals be sent back and forth that likely most standalone systems would not provide (or may not provide in the correct format or timing) for the ECU / TCU to be happy. There's sensors everywhere that are required for proper operation because as Jason mentioned, all the systems are tied together from Engine to Transmission to ABS to Suspension, etc... They are all programmed to see each other and talk to each other. If there is a missing communication present it usually results in a limp mode condition. it's honestly just a good bit of work and may not be worthwhile to figure it all out.

One thought may be to go standalone ECU for the engine and look into building a custom adapter to another transmission or perhaps pairing it with a 4200 6MT Manual Trans. But I haven't really looked into what compatibility would really be possible especially because it's a transaxle setup. It's going to need to be something whoever is doing the work is passionate about to help get through the lack of public information on the platform and stay determined to complete.

Best Regards,

I missed the part about wanting the F1 transmission portion. If you remember what some builders did in the past, they took the whole car apart and swapped over the parts they wanted as well as the entire wiring harness and accessories, I think it was Foose in the early 2000's. Like I and FD mentioned, engine with a MT fairly doable with a standalone ECU, there have been Ferrari swap along that line, like the Rambler one. Adding the F1 trans would be a challenge possibly.

Since you have the donor car complete it would be a great project to tackle if you have the time and resources. Check out what Foose did at that time.
