Bloody Hell!

Something is wrong with their dyno then :headhack:

hi Daz...

you could say i'm getting a bit fed up with it all.

.............but i will add that my bike STILL has alot more top-end UMPHHHHH than it did when "Standard".....

I once had free dyno time when a friend had his own dyno, I managed to do many tests on 90% of the XT660 mods.

These days I have to pay like you, that is why I bought a Wide band Commander 1, http://www.widebandcommander.com/ I can build a perfect fuel map for my bike no matter what mod I add to the bike for free. I can spend as much time as I want to perfect the map under real riding conditions.

kev...could you just look at the 100% column and compare with my earlier dyno map..........does it make sense that with the numbers on the map just sent, that the AF is richer? i think it does to me.....but only in certain areas.......

Their numbers do not make sense to me at all.

I will load the map you just sent me today, I will do a full power run at 100 throttle & post the results for you Saturday afternoon.

I am riding Saturday morning so I will do it after my ride.

wow, that's great..thanks mate.!

What I do find strange is that they have mapped the Power Commander to 8000 RPM where it is impossible to rev the XT past 7200 RPM.

Kev....the DNA map, "open Ackros" that my map had derived from, had those figures in....i s'pose they just left them there............

How many miles you got on it now by the way?

If I remember rightly, yamaha states that the bike will only be run in till after around 1000 miles anyway, couldn't help but notice you were dynoing it after 700?

the book states I think, 1/3rd thottle till 600, then 1/2 throttle till 1000 so the engine may still be a bit tight.

Just an afterthought...

Great news breaking!!!!!!..............

Dynojet UK rang the Dyno I used, and got them to check their Air Flow Meter.

The Air Flow Meter had a sticky valve !

I asked Dynojet UK if this could be giving me AF ratios 1-2 points out, and they said it probably could !

It gets better .....

So the Dyno have ordered a Service Kit for their meter from Dynojet UK, and then......they are going to get my bike back there, and re-dyno it!!!!!
