Another guy with the same setup shared this map earlier. I'll probably have my 143 assembled in about a week - still figuring out how to mount my oil cooler.
I also have rearsets and the Ohlins rear shock. I actually have the Ohlins front for inserts too, but they are in a pair of shocks that is bent, so I'll need to swap them.
Where are you tracking the bike?
Are you using the stock injector?
The job was tedious but not hard. There's no cutting or soldering wires, just relocating 4 female pin connectors. I used the pin numbering chart in my Grom Service Manual. Remember that chart is for the male ECU itself, and not the female connector the ECU plugs into. So the connector is a mirror image of the numbering chart. I made damn sure I was moving the right pin connectors to the right locations before I touched anything.
Once the wires were in their proper locations I simply plugged in the ECU and haven't touched it since. I've been using it for about 3,000 miles and it works just fine. It adjusts itself to the constant intake and exhaust changes I'm always making. It even compensated for the PXC 150 injector I installed. The bike runs great!

Thanks Tooter, that is very helpful.
Yeah, I've been planning to go to the kart track for a long time here in NorCal... Maybe I'll finally get to it when I finish the 143cc upgrade.
Only issue is I have nothing to tow it with.
I like the idea of auto tuning but dont like alot of the extras that are required. I have 16000 miles on mine and would like to keep it a few more years. I dont want to even think about big bore or super anything yet. Most mods havent caused issues but anytime the engine or internals gets involved, I have always had issues. I do have a cam, intake and exhaust, ecu reflash and a few sprockets that I can change out, a speed ohealer when needed and a fuel adjustment piece. When I took all of the extra stuff off my grom has been more reliable. Just dont want to sacrifice that.
