Guhl Ecu flash

Hey guys just thought I would share this.I just had my ecu flashed by Guhl motors it does the following,Optimizes sub throttle response,reduced engine braking affect,removes soft throttle in all gears,aggressive ignition timing in all gears all throttle positions and adds ignition timing in the low to mid range,removes factory speed limiter and raises rev limiter 500 rpm.Really improved throttle response along with better low-mid range power nice power curve alot smother.I am very happy with it

Hi. I want to flash my ecu but have no idea where it is. The workshop manual says it is on the left hand side behind a panel. I have looked there and also lifted the tank. Any ideas please.

It's up near the front but to get to it you also have to remove the airbox after lifting the fuel tank.
