i was just about to type a general question on this matter. I am having the same sort of problems ENOUMOUS flat spot with spluttering around 4k to 4500 and then the bike picks up with vengeance. Off throttle it pinks when slowing in a gear. But 1st thing in the morning when everything is still warming up...no problems what’s so ever?.

james - dont they ALL have a flat spot at 4k? I have an FIM and mine still does...

I've just had this with mine.

Have you fitted open pipes/filter without fitting a power commander/FIM eprom?

In my case the fueling was out.

The nice man at moto rapido sorted it out for me.

thank bu66ery for that. weird thing is it does it only when the bikes around 190f so till i hit traffic everything is happy. Mike from MDR said it would be a power commander to map the issue out even though it has been chipped. Not sure if its a FIM chip in their. Is it obvious when peeling back the sticker on the ECU? and DAFT question but is the EPROM light erase. ( you erase the contents of the chip by peeling back the sticker ontop of them)

the 996 has had the following done. Termis 50mm standard filters and the restrictors removed.

I guess just one of the annoying things i have to live with till i have enough ££ to through at it again?

are you me?

I have a 996 bip in pretty much identical spec apart from an ITG air filter in the airbox.

Mine had exactly the same huge flat area (no way was it a spot).

I tried several eproms, to no success.

The problem was that the mix was down to 1.8%, Steve at Moto Rapido could adjust it to 3.8% which is still a little on the lean side but there isnt enough adjustment to go any further.

My next step will be either an FIM or power commander and getting it mapped.

The eproms will erase in UV if you remove the sticker on the eprom itself, even in daylight if left long enough.

The FIM eprom is identifiable because it sits on a secondary daughter board of its own which plugs into the ECU.

A good setup of balance, TPS, mixture etc got mine very rideable with only a slight hesitation if given a lot of throttle at low revs.

yea...SNAP

mike from mdr said that he has set it up with the correct fueling. Before it was running very rich which would explain why the problem wasnt so obvious.
Now its setup correctly, but has this annoyance.

granted its really only a problem when you open it up abit at 4k but seeing iam usually around there whilst riding its a bit annoying. also on part throttle in low revs it slightly back fires through the injectors...is that normal?!!!

Is the FIM module located inside the ECU? like an expansion card with ribben cable attaching the two device 1 into an eprom slot adapter the other into the FIM module? or it it external like the power commander?

I blame the s0dding EEC and there noise emissions..noisey cans save lives....officer honest

If so ..and i think this has been answered before in a thread..power commander or fim.. and... who best at setting them up in and around surrey. would do nelly but thats a bit of a trek. any issues with SIGMA? motorapido is a little ride around the m25 and then there's the question of getting back as i guess it would be a day job

I had Sigma do a bunch of similar work to my 996 a few years ago. I had the grunter spec done and I can't fault his work.

I had all of this done and the bike went like a rocket ship when I got it back.

Incidentally, the gent that Neil mentions in the article - Ian, is our very own 'the old man' who posts on here and races in Desmo Due. He had the original 'grunter'.

Tetol also had a grunter.
