Title: V85tt E5 Check engine light after mods?
Post by: fastlaners on July 12, 2023, 10:50:10 AM

Hello All; I recently did the SAS delete kit and tip over valve, evap tank modifications;
-2022 V85 E5 Travel
-SAS delete kit installed; ( Yes; one bolt on right side plate was a challenge ) installed plug that came with kit on air box ; capped all other connected hoses and left unit plugged in.
-Tip valve and evap mods; gutted tip valve and left hose going to evap canister; cut other hose off top of canister and plugged all other hoses including one that goes to manifold also left unit plugged in.
-installed Mistral big bore header kit and y-pipe without catalyst, MassMoto carbon slipon with db killer, K&N air filter
-Then performed Upmap download; once complete; I took bike for a ride; smoother throughout the rpm range in all gears; much more lively feeling; seemed like less heat off cylinders; The only negative drawback is I have a flashing yellow check engine light; Upmap app. shows P1309 error code; any input or help on this issue would be appreciated. Thank you, John.

I guess non else has done what you did to the bike.  Mine is still 100 percent stock.

    Code relates to crankshaft position sensor. Possible remap has an unknown or bad value.

needs the tone wheel learning done.

There is a hack that works on the same 11MP ECU in the Aprilias, RS660 / V4.   Probably will also work on the V85

Will messing with the ECU void the warranty?

I'd have thought everything else you have done would have already voided the warranty.
Why worry now?

Yeah.
My V85 warranty was voided before I got home.
I don’t know why though, I only removed the ugly bits… :wink:
