I've been thinking about it for conversion on a friends stock 3.0.
The only problem is microsquirt doesn't have a flyback circuit so it may not handle the low impedance injectors alfa use.
The DIYPnP is a microsquirt whith an expansion board, i think that you can put the flyback circuit there.

Anyway, Motronic has high impedance injectors as far as i know and the Diypnp has the 55 pin connector.

Earlier motronic has 35 pin like the first L-jetronic ones, and the later or le2-jetronic has a 25 pin connector.

The best way is to get an assembled unit of Ms-ii v3.0 and make a little harness between MS and bosch, or an adaptor like this one:

For a 3.0 engine you need a 3.0 ecu, or the 3.0 chip.

Luis, thanks for the reply. Please can you tell me where I can get the appropriate adapter that would allow me to connect my 3.0 ecu unit into the the existing wiring.

Regards,
Rao

You need the wiring harness that comes whith the v6 engine, the 1.6 wiring doesn´t work whith the 3.0 one (more cilinders).

If you want the 156 wiring you need to change the 2.5 ecu for the same version of motronic of a 3.0 (maybe a 166 or a gtv)

Another option is to change the software in the 2.5, maybe squadratuning can upgrade the software of the 2.5 ecu to a 3.0 specification.

I'll counter that, tho purely for the sake of argument .
Well respected Australian tuning company Nizpro, use to apply MOTEC computers to everything with their name attached to it.
When the BA(model) Ford Falcon XR6 Turbo came onto the market, they used MOTEC computers in their modified versions. But when the SCT flash tuning interface software became available, Nizpro were quoted (in a local magazine) as saying the MOTEC didn't have a patch on the hugely capable factory system once they were able to tune it to suit their needs.
They were so impressed with the factory Ford system that they even applied it to their quad turbo (don't know why they'd use 4 ) Nissan VH45 V8 competition ski boat engine (that previously ran MOTEC).

Just for the record, Nizpro built the fastest, Australian built cars. A short run of Nissan 200SX-R's that were officially Australian made cars back in the late 90's. They had MOTEC's (amongst many other things ).

Im not tallking about Ford,Im talking about Alfa.This is 2009 and things have moved on alot now.

And having used Omex,Emerald,and DTA previously and quite recently too,I can say that Motec is the best for my needs and uses.Both in my road car and in my race car.

I even use their SDL digital dashs in my cars,they are that good and accurate management systems and dashs.

I'm not specifically talking about Ford's either, but rather the capabilities of the modern, factory engine managment systems, once there is software support/interface to tune them.
So much capability, that a high profile tuning company applied it to an engine that was formerly run by probably the most world renound aftermarket system (MOTEC).
The same as the local turbo and supercharger kits for the LSx powered Holden Commodores. If the kit provider/tuner is using an after market system, then they're doing it wrong.

What I'm trying to say is, even the absolute best aftermarket systems aren't as well developped as most factory systems of the last 5+ years. It really comes down to pure finances. What aftermarket supplier has the finacial resources of the likes of Ford, GM and Bosch?

where do you find a board like this?

I have gotten a spare Motronic ECU from a junk yard, but a fresh connector would be nice. I have found a place in Australia that sells the connector alone for 65 USD and shipping is another 50 USD.

I was just on the TWM Induction site and noticed they've added some new hardware. Also, check out the two Alfa engines w/TWM throttle bodies. Are those guys on the bb, I wonder?

Eliot Shanabrook is around somewhere. I've seen that name either here or on the Alfa Digest.

Unfortunately that adapter board is for the 55 Pin Motronic ECU. The 35 Pin one was never designed. Maybe not enough 35 Piners around?
