Battery charger choice for tunecu flashing

[Planet3]

TuneECU is not the load issue, to flash the ECU the ignition has to be on and all the bike's sensors and systems (inc fuel pump) are active. The headlights/DRL's will also come on hence why you need to pull the lighting fuse and switch the DRL's off.

So the lights setting needs to have that green light icon off?
I guess the fuse takes down the main lights, not the LED lights.

Yeah this was a better worded version of what I was going for, it's all the other systems etc that will draw while flashing not to mention the ecu will probably cycle and repoll all these systems several times during the flash.

If your not going down the route of a battery charger I would at least grab a car battery / spare battery and jumper them in parallel to keep the voltage and amps up longer.

A friend of mine, Jamie from S and R Pro said that to me yesterday. Drive my car up to the bike and use jumper cables from car to bike. Another good option

Another good option just make sure your not running the car, you don't want to spike the voltage, the number of amps and voltage your car alternator can push in that instance could kill the bike battery / systems.

So just make sure your jumping it with car off and nothing in the car is drawing anything, I'd be more inclined to jump it with a spare

Makes sense. My car is 4 years old so the battery wouldn't be ideal

This is not a difficult thing to do...just put a car battery charger on, pull the headlight fuse and start the procedure. As long as there is charge going into the battery and the headlight cant draw power youre good!.

Short answer, yes. Long answer, I pulled the headlight fuse, but forgot to throw the DRL switch to turn them off. Didn't matter, my particular charger maintained the voltage anyway and my flash was successful.

Seconded!
