The default log file saving location is in C:Program Files (x86)aRacer ToolsLogSave, or you can save as to other location

■ It is hard to start the engine today, but it have no this issues in yesterday
1. First have to check the fuel injection and ignition are working well
2. Please make sure the sof and amp/amr/ams file are the suitable for your bike
3. If you are the first time to start engine with aRacer ecu, please make sure you already key on for a while and key off for ten seconds to reset the ecu.
4. If you can start engine with a little open the throttle, maybe the fuel of the cold start have to be tuned.
5. Please link with the laptop by iLink, open the speedtuning and check the parameter Miss_CRK_Cnt(Crank missing counter) have increase, if yes, you have to follow solution of crank missing count
■ The motorcycle engine can not running well, the Miss_CRK_Cnt) is continue to increase

1. The gap between crank sensor and tooth is incorrect, the spec is 0.5~1.1mm.
2. Generator rotor have to be tooled, have to change it.
3. Regulator damage, you can plug off the regulator to try it
4. If you change the main wire harness, it may happen the wire in the crank sensor connector are reversed.
5. Flash to wrong sof file may cause the coil or ecu damage, please make sure the sof you flash is suitable for your motorcycle
6. Please check the intake and exhaust valve clearance is suitable.

■ Idle rpm is too high after engine start

1. If you saw the "ISC air flow" in speedtuning is too big(normal is 20~40), you can follow below step to fix it:
    1.1 Re flash the SOF and AMS/AMP file in speedtuning
    1.2 When engine key on, turn off and turn on 10 times in 15 seconds and key off the engine

2. If the "ISC air flow" in speedtuning is too small, maybe the intake air have leak air, please check the throttle body, intake manifold, you can use the throttle body cleaner to spay on all the intake area, if the idle rpm change suddenly, it is mean the intake leak air, please fix it.
