Moto Guzzi Griso 1100 ECU remap after engine tune and dodgy ECU (in the post) re-flash

Posted January 15th, 2016 in ECU Remap, Moto Guzzi.

The owner of this Guzzi Griso (with skimmed heads, open airbox and Termi pipes) came to us after falling into the trap of getting a re-flashed ECU in the post… that didn’t work very well. He’d also added a Power Commander with Autotune that (in theory) ‘self tunes’ the engine as it’s running.

Now they have a place if you want to make a quick map to suit a ride (like you do) but otherwise they tend to tie the engine constantly in knots, we find. It certainly wasn’t working for a bike like the Griso.

We started by stripping the Power Commander off then sucked out the ECU’s mapping. No wonder it didn’t run, the map was a disaster! It had zero fuel wound in at 40% throttle at 5,000rpm. It was a clown’s comedy map, minus the red nose and big shoes.

So we sorted a proper fuel map to suit, tweaked the ignition and blimey, it’s a new bike. Lovely job. We’ll make one point to finish off – a map needs building specifically to suit an engine. Generic maps are, at best, one size fits nobody or, like the one flashed in here, a joke.

The re-flashed map in the Griso was no good. It now has the fuelling and ignition that the (lovely) engine deserves.
