Thanks for sharing this. Currently running the mini 5 with the AF1. Wonder if the X with af2 is worth upgrading to.

When cold, the aracer has never given me a solid idle. Once warm, it is fine.

I use auto tune but played around with the targer afr setting compared to stock aracer targets. I run it a bit more rich at high power settings.

One day I should get it to a dyno and have a tuner dial it in.

Thing is just off.... Sometimes it reads & runs right (great when it does), other times I does not read the TPS until 1.8+%, which throws the tune off all over the map, will not idle, stalls at lights, PITA to start! Anyone else have this happen? Just bought, charged, and installed a NEW 4ah AGM battery with 80CCA, should be plenty since I have nothing else connected to the bike.

I am sure your battery is fine.

I have the same complaints about idle. Sucks.

BUT it does the job where it counts near redline under demand.

I got used to having to milk the throttle a bit at idle to not stall . I avoid stopping in general

Run a higher than typical idle speed, adjusted by the cable adjustment and set screw, to get a reliable, but high speed (2K), idle.

Never paid attention to TPS after initial setup and autotune.

Great find. Had no idea.

Yeah, apparently the AF1/AF2 are powered by the ECU, which cause the ECU voltage to drop & make it freak out.

Report back after trying the fix!

Great info. Thx!

Your dyno guy will tune your bike through the aracer app?
