There's not much to really see... it just looks like any normal BOSCH Motronic DME/ECU, but has a vacuum line coming out of it.

There's a variable BOSCH TPS which bolts onto the existing throttle body and a new BOSCH NTC IAT sensor which is installed somewhere in the intake tract, post i/cooler.

The rest of the magic happens inside the ECU, where the ignition/fuel is mapped according to engine load/boost for 93/94 octane pump grade fuel. The variable TPS provides acceleration enrichment.

I'm hoping to spend some time this weekend installing it

Protomotive are also sending me a larger throttle body to compliment the new ECU
