MARK’S GRISO FUEL MAP REVIEW (somewhat long)

[Vasco DG]

Did you re set the self learning parameters?

I didn't reset until after the first run on the Saturday. reset after that run and then everything still okay on the Sunday.

Do you think I should re-install, set the CO trim and reset the learning parameters and see what happens?

Cheers for the response Pete.

No need to reset the parameters again. Try setting CO at zero.

Okay mate....I'll see if I get time this weekend.

Thanks again.

The rest of the tune is right? Valves set at six and eight thou, (0.15 & 0.2mm), TB's balanced? No messing with throttle stop or linkage rod?

Right - My Carbtune arrived yesterday!

I checked the throttle grip and cables - all okay now (one cable was welding itself on to the rocker cover so I've re-routed that - it operates smoothly so I asume it's okay).
Checked the airscrews, both wound out a bit.
Balanced the TB's and set the idle.
Reset the TPS.
Did it all again :)
Reset the CO trim to 0 (it was -3, not -5)

Went for a 30 mile ride to collect some work parts.

Much better now, apart from some drivetrain backlash when closing then opening the throttle.
So, I tightened up the cables a bit which did help somewhat.
Got home and found the revs rising on left lock so I've adjusted the cables again and have yet to try it out.

Idle is between 1,000 & 1,200, nice and low (maybe too low hence the backlash - a shame you can't really adjust the idle).

Smells a bit of fuel so I'll try going backwards again with the CO Trim on my next graunching session.

Thanks for the advice; I'll check the tappets next week when I have the gear and do it all over.

I'll see what it's like on my next trip out.......Cheers :BEER:

You sort of can. In the software, you can set 'target idle'. I've had to do it for a couple of Norges. Adjust the CO trim first. It might be a tad rich at idle.

And definitely set the valves at 6 & 8 thou.
