Hello,
I am in charge of tuning a car equipped with an Hayabusa engine and a Vipec V44.
Car was running prior to coming to me (although i never saw it running) and was tuned.
The owner wanted me to retune it after swapping his '99 engine (8teeth multitooth) to an '03 engine (24-1 trigger wheel).
I tried to upgrade the firmware because the last tune was from 2012 or something.
It failed to upgrade, giving me an error message, and asking me to cut power to the ECU so the fw wouldn't be corrupted.
Now when i power the ECU up, the blue LED lights up for a few milliseconds then turn off.
On the computer, software keeps going from connected to disconnected to the ECU.
Prior to this, i could stay connected to the ECU and work on the tune, no problem.
I attached a tune if it is of any relevance.
Thank you for your help.
Cheers
Max
trigger 24-1.pcl
