Building a My16M Fuel Injection ECU.

 

When you're not satisfied with the performance of the Weber Marelli 16M ECU, you have a number of opportunities:

• Adjust TPS, low range mixture pot-meter, bypass valves, and balance till you drop.

• Buy a different EPROM

• Install an extra black box (Power Commander or equivalent) to alter the injection signal, and maybe the ignition timing.

• Ditch the Weber Marelli, and install a third party ECU.

 

 

I tried the adjustment fix, but I was never quite satisfied with the result, it still had the occasional misfire at 3500-4000 RPM, and the idle was never as stable as on my old Le Mans with 40mm Dell Orto's.
