999s fettling.........

Some info that any one planning to tweak their 999 might find interesting.

Last autumn I fitted the full 57mm Termi system with DP ECU and filters to my S.

The bike was run for the rest of the year without any further adjustment.

I put it on a dyno in September just to see what was going on and the results were promising, although fueling mid range wasn't brilliant it was usable. (see earlier posts for graph)

I resisted fitting a PC3 at that time in anticipation of any early release of the FIM ECU and because I was loathed to add something to the bike just to fix something that wasn't working properly, i.e. the DP ECU.

With 3k on the clock it was time for a service anyway and after discussions with Neil Spalding at Sigma decided we would go for a Monty plus a few extra's. The brief was to end up with a user friendly bike biased for track days but not a full race tune.

The motor was stripped, checked and reassembled with precision. Heads were ported to match the 57's and volumes matched - something I understand that twins react well to. Cams and rockers were superteched.

Following a run on the dyno it was clear that the adjustment available with the DP ECU just wasn't up to the job fueling the new motor correctly and be-grudgingly a PC3 was fitted. (A Corse ECU is available, but at nearly 1k I felt that it was going too far)

The PC3 did its job and the bike is now spot on.

Here's the good bit......

Remember this is a standard 999S motor, no motor tuning parts have been used, valves and cams are stock and its running standard factory cam timing.

Nearly 70 ft/lb torque @ 4k rising to over 80 ft/lb @ 8k and staying there to the limiter!

Almost linear power curve 100bhp @ 7k, 125bhp @ 8k, 135bhp @ 9k rising to 145bhp @ 9.5k all the way to the limiter!

(obviously the dyno figures are not absolute since different dyno's will determine slightly different outputs, but if I were to take it back to the shop who ran it up last September I would be seeing 150bhp + at the rear wheel)

I'll post up the graphs when I get a mo, but what the numbers don't tell you is what a clean, crisp and responsive motor Neil and co. have built.

I cannot praise the team at Sigma enough, simply outstanding.

yes my question too i know the full monty is 700 ish plus bits looking at 1k i guess.

mines still being sorted by ducati uk to get the power in a decent ballpark (valve spring was broken, resulting in only 120 at the rear) when thats done it will probably be off to neil too.

The Corse ECU removes the sidestand interlock and increases the rev limit to 11900. I understand John Hackett can organise the increased rev limit on your current ECU for a much lesser amount.

Costings.............

not as bad as you might think......

Full 57 ti system, filters and ecu 1500 (negociated with the dealer when I bought the bike)

Full monty 945 plus 240 parts. remember that this includes the equivalent of a 6k service and the blueprinting which only needs to be done once during the life of the engine. It also includes suspension work.

Superteching, my choice for peace of mind 125.

Head work, worth doing to get the most from the 57's, 500.

PC3 including set up, dyno time, etc 360. Again, not my first choice from a set up point of view since it maps both cylinders indentically.

So by the time you take the cost of a Ducati main service out of the equation it does'nt really cost that much to get your bike set up properly.

Even if you were'nt planning on developing your motor I would most certainly recommend a monty to replace one of your major services.

A couple of other snippets of info. You can have the bike set up with different cam timing if you wish which will modify the power curve, I chose not to. And, the cams, belts and rockers were all in very good condition after 3k
