    Short time ago I installed my new PCV with autotune. Really happy with the performance.

    But on sunday the I had the brilliant idea of updating the firmware (even if it was not needed).

    After updating the firmware of the unit from v0.1.3.0 to last version (v0.1.4.0), the unit is not reading TPS voltage (it shows 0v) and AFR reading is 000 (my unit has the autotune module on it) .

    When updating at the first attempt I got a fault message, but at second attempt I was able to upgrade the firmware.

    First I thought it was a loose connection , but everything seemde ok. I also measured voltage on TPS and it was OK.

    Last time I rode the bike everything was ok. I’m pretty sure of this, because I had accepted trims, and trim table was on 0 before ride. After, it was filled like expected on many TPS RPM combinations (this means AFR reading and TPS too). After this the bike still runs, but not good. I think it still adjusts, but supposing TPS is 0, and autotune is not workign (0 on trim table).

    Someone has this happen?

    Thanks
