Dimsport Evo review

I had the Dimsport Evo installed on my Supersport S. I already have the Ducati Akropovic full exhaust system.

The results were impressive. But before we get there you need to know where I live. Johannesburg, South Africa...at an altitude of 1750m (5750 feet) above sea level. The rule of thumb is that normally aspirated engines loose about 12-15% of their power up here compared with the coast. So 113hp becomes about 99hp or so.

The chart shows that the base (dark blue line) was 93.2hp at 9091rpm and wheel torque of 77.8nm at 7118rpm. The after line (I had to trace it over) was 115.7hp (22.5hp gain) at a slightly lower 8841rpm and 107.1 nm (29.3nm gain) at 7119nm, a 24% and 31% increase respectively. The light blue line can be ignored..that was a whoops, they initially used the wrong Ducati wiring harness and then corrected it.

Of interest is that the extra torque gain is a bit more pronounced at lower rpm...job well done Dimsport.

Top speed on the clock is 244km/h (151mph)...at altitude about the same, but enough. But I would never do that of course.

Charts are objective, but my butt never lies. What that told me was that the engine not only felt more powerful but also smoother and more eager to rev and spin up more quickly.

Fuel consumption...eh who cares...but it doesn't seem to have made it worse...other than my increased keeness to twist the throttle.

Overall it was a success and the results were better than I expected. At a cost of R8500 installed and dyno tuned/tested (USD600, GBP462, EUR535) I think it was well worth it.

Thanks for posting, interesting...

We have several Forum Members that are very experienced with Dimsport Evo, but donít think they had gains of this magnitude. Are there any more specifics available regarding the set up and/or parameters used, etc?

I didn't do the installation and setup so can't speak to the specifics of how they set it up.
The guys at Fire it up through a division of theirs performance technic did the work. Pop them an email they good guys and will probably be happy to share. I think that they get their training in Italy at Dimsport. They also have a pretty sophisticated fancy new dyno. No I don't work for them or anything, I'm just a customer. Www.fireitup.co.za

wow. This is a stock engine with exhaust system? This is an add-on module that made 22 HP+ gain? wow indeed

Is this an alternative to Power Commander?

Yes the engine is stock. The only thing other than the Dimsport unit is the full Ducati akropovic exhaust system and a performance air filter which I think came with the exhaust system and was already on the bike before, so the gains can only be ascribed to the Dimsport unit.

Yes it's an alternative to power commander but don't know the exact difference between them. I'm told that both world super bike (SBK) and MotoGP use Dimsport which is an Italian company that works with the two series.

I saw a white SS with akra race outside Llewelyn's dyno room (fire it up) two weeks or so ago, was that yours. From my experience, the dyno operator can make adjustments to the drum brake resistance and altitude air density to fudge the results, fudged results make customers happy when they are chasing HP.

I only saw 4 SS at the ducati day at kyalami on 11 May, 3 red and a single white... Did you attend?

I and others here have Dimsport enabled bikes, can you share your map? Its straightforward if your PC is connected to your bike, else perhaps your tuner has a copy they can email you.

Yes that must have been my white bike with the Akropovic.
I didn't tell them that I was chasing HP or give them.any specific instructions. Maybe they jippo the system to show more but I don't see any reason. Guess it also comes done to trust of the company.

I've asked the tuner to email me the map settings.
