ECU flashing

[sidewaysid]

HiBeen reading a little about flashing the ECU to get rid of the jerky throttle at lower revs, my bike is a Gen2 FZ1, do any of you on the forum have any ideas about this, would it be expensive and I bel;ieve the ECU is under the air box.

If the bike is pre 2011, a Fuel Cut Eliminator will probaby do rather than a full flash. The Gen 2 up to 2011 cuts the fuel when decelerating from certain speeds and there is a delay when coming back on the throttle. First time I rode one to check it out for a friend who was buying it, I thought there was something wrong with it.  The owner said he never noticed it, but I was coming from a carburettor bike and it was very obvious to me and drove me to distraction riding it.

You have 3 options, from cheapest to most expensive -

- Fuel cut eliminator - plug and play
- Send the ECU of for flashing  - https://www.wizperformance.co.uk/product...-ecu-flash
- Take the bike to a dyno shop where they program & flash a better fueling curve to remove the dip at 5k rpm.
- Installer a Power commander and then also take it to the dyno shop. The PC allows them to tune the fueling curves further.
