ECU remapping from Guhl Motors

[Burchy]

I reckon your engine was pretty sick before they started on it.  My bike is stock apart from a Beowulf can and a dyno run showed 148 at the wheel.  They were disappointed not to see 150+ because they couldn't blow enough air at it for the Ram-Air to fully kick in.  Seems your guys managed to get the ECU back to where it should have been in the first place!

I still have a bit of that on/off switch as described above, though and I wouldn't mind having that removed

the on/off throttle from zero ? Take ALL the slack out of the throttle cables.

Will have to check but I don't think there's any slack.

Here's the sort of situation where it shows up. Approaching a RAB, throttle off, rolling in letting the engine slow you while checking its clear, good to go, open throttle (no matter how gently) and there's a noticable kick/jerk as the motor comes back on. Now I know my car (Honda Civc) does it because it's crappy fly by wire AND the ECU cuts the fuel completely on the over run. Tickle the pedal, and bang, neck snap as the engine re-ignites. Drive it like you stole it with VTEC kicking in everywhere and all is hunky dory, try and apply some finesse and ... well    The GTR's not that bad and maybe a few more miles will sort me out (coming from a Pan which has a very soft/forgiving delivery).

I've heard that the Throttle Tamer helps as does fitting a Power Commander. Haven't tried either but taking out all the throttle slack does help.

This is the before and after on my bike with regards to mapping the ECU at Hilltop Motorcycles. Its now as smooth as a baby's arse.

This is mine.. You can see that the A/F ratio is pretty much spot on until the last when it richens up considerably and the power falls off.  A bit more puff from the fan and who knows?

Interesting that there is only ½ hour between your two runs

No idea about the half an hour, i was there an hour and a half, four runs in total, but happy as Larry so to speak.
