Project: Grom 2.0

The AF3 is tiny compared to the AF1 and easier to tuck away without miles of extra wires like what I had.

Here is the finished setup with the Mini Xx

I will need an adapter plug to connect a direct power to the AF3 as I hear power can fluctuate if the AF3 is powered from the ECU, which is a bad thing. So I will tap into the taillights for a constant power source.

Later tonight, I will put in a new spark plug so I can get the tuning started.

Spark plugs on these swaps are rough as you need to remove the radiator to access the coil and plug.

Still struggling with throttle issues. Hopefully the new TPS is the fix.

just glitchy? Whats it doing?

daytona, i was mid corner when the throttle cut out and kicked back in. the bike wheelied and i nearly crashed. the bike would cut out and back in randomly. i started watching the aRacer on my phone live while riding and noticed at 12-14% increase in throttle position, even at red lights. i thought the old aRacer hardware i had was the culprit so i replaced it with the newest ECU and autotuner. once it started happening again, i went for the TPS sensor.

this morning, i flashed the EXU back to stock to make a new map on hopefully accurate TPS data

well, that sounds fucking awful

Updated the ECU to the newest firmware today which meant starting over on a fresh map. Was thinking about doing it anyways as the 125 miles on the current map being made might have faulty data from the throttle positions.

I rode 18 miles and it was riding like a dream. No choppy throttle. All smooth. Even fixed the bad throttle input I always got from 1st to 2nd gear. Too soon to say it was the TPS sensor but it’s looking good so far.
