Daytona T595


icon12 Aug 2012 17:25
Hi all-not been here in a looooong time! Been mostly playing with my Millie R and a few excursions on an old Blade of mine..

Anyway been tinkering with my M2000 equiped 595, i think one of the reasons i don't use her much these days is compared to the Millie the fueling is so damn poor on very light throttle that its horid to ride through traffic and 30mph limits etc.
I've downloaded a high pipe tune to suit the bikes set up which has improved things but its still pretty poor.
The main issue is holding a very slightly posative throttle to say reduce the rate of deceleration or to pick up the speed slighlty in traffic where it stumbles and hesitates and needs a bit of clutch slip to cushion the drive train...You know-the usual type of stuff these early bikes are famed for..
Above 3.5k she's fine and on anything over a 10% throttle at all revs she's fine...
What i need to know is which way to adjust the fueling as any alterations i make with tuneboy don't really improve matters much. Ultimatley i guess i'm just not very experienced with Tuneboy/adjusting maps and could do with a few pointers.
Has anyone had experience they can share!

Many thanks MF

Could be valves,IVAC hoses are all good and TB's were balanced...

Generally, these early bikes we're known for their poor low rpm fuelling, so was this down to being set up a bit lean or a bit rich i wonder?

I'm currently having a dyno created/Tune ECU map made for my 2000 Daytona with underseat exhaust. The description of your low throttle issues is so similar I thought I'd share that the first thing the dyno guy mentioned was that it goes very lean right off idle and up to about 3K.

Currently running the high TOR fuel map 10072 which I guess is similar to yours? If you look at the map in TuneECU the graphic representation, press F5) shows the 500rpm and 1000 rpm fueling curves do some things I've never seen before on any other map.

Good luck

I'm experiencing much the same on my 12/97 build T595, low speed running is atrocious anything below about 3k rpm, above that heaps of power until a flat spot around 4k and then fine up to about 6 or so.
Just got my usb cable so need to check what map is loaded and then see what will work best for the high mount CF can .
