Hi Looking to smooth things out and calm down the pop-pop on over-run. Just called a tuner, was told there was not an awful lot they can do with a 2001 996. They suggested a Power Commander (705-411 (916/996)). Does this all sound right? currently I have a 45-50mm Termi system and a MS104 chip (whatever that is). Thx
I wouldn't fit a power commander before having the balance & CO set up by someone that can! Will make a noticeable difference if the TPS, balance and CO are not spot on.
The power commander would be the new map; quite a few available for download, if you wanted to spend the money, a tuner could create a modified map for your bike on the dyno.
CR I don't know Ducati's but I have a power commander 3 on my 998. I've had many over the years. USB3 types. Install is bike specific, stock loom that went to injectors plugs into power commander, loom from power commander plugs into injectors. Power& earth I think that's it. I know you can wire a full throttle up shifter from it.. If someone emails you a map for a 996 similar spec you could put it on to a power commander with a laptop in about 3 mins. The cable is cheap on EBAY. I'd recommend making a copy of your sorted map and keeping it. The website has a free download software section last time I checked, there are some base setting maps on the website but these can be quite far out if you go to a dyno. There are some vids on youtube too. > I found on a tuned GSXR (ported, high compression, cam and ignition timing) the stock ECU was safe, a few flat spots mid to low end. The power commander only made 1HP more peak hp and smoothed out some flat spots.. I guess the stock ECU is a bit rich on that bike to deal with different ambient temps and fuel qualities. It still made 200hp at the crank... 175Bhp at the rear wheel on the stock ecu with the power commander un plugged. Most dynos can set power commanders up easy, via probe in the exhaust or lamba. Although I've had a very quick look at my Ducati and the exhaust pipes seem to go separately from each head to into each silencer? so a bit more or a pain at the dyno. If you start mapping each cylinder separately it will take more time if the software permits it. I've never run an auto tune. I have always run power commanders on my race engines, regs did not permit re flashing ecu's in the factory run championships. I do know people who run modified ecus on some seriously tuned engines but I don't see the need really for road use, although I am not familiar with Ducatis so maybe missing something. I guess a bit of ignition advance might work but I don't know those parameters, I prefer to run safe and run something I can work with. I can always put the saved map on my computer back on... and check it works in my garage to some extent. If a dyno can take a reading it should be a quick job for someone who know's what they are doing assuming it is running ok at the time... if it takes longer than 1 hour I'd walk away. It's easy to tell throttle position on the power commander too, it should read 0 shut and 100% when fully open - these points can be moved. This does not mean it is correct for the ecu.. that is a different process, the power commander values can be altered to make a tps that is wrong give the correct range on the map, while the ecu might be all out of sync. It's easy on a gsxr to do TPS calibration (doing it via a multi meter with ohms readings is a bit hit and mis) GSXR, I recall while in dealer mode, rev at 3000 rpm a line comes up on the dash and it should be central. When you start racing unless you are rich it pays to learn this rubbish specific to the bike, if you can find someone who has raced a 996 your laughing. I've seen good, bad and ugly dyno operators and the more you pay has little to do with it. If they want it overnight and keep changing values don't trust them, experienced guys will punch keys as they run and job done.. If it runs fine now, you might just get away with a base map and few tweaks on a power run. with some short shifts etc..

CR the eprom on a 996 can be reflashed just like most bikes and a call to CJS will confirm cost, how much better (and why) they are than a well set up pc3. Having gone down the chip, then PC3 route I ended up having my 748 ecu eprom remapped and wished I had not wasted my time and money with exhaust chip and then pc3. Even though the pc3 was an adequate state of tune it never felt that sorted even though the power and torque figures were pretty good (similar to the full remap). Bottom line is if you want it running correctly across the entire throttle and rev range the mapped ecu is the only way to do it properly and it is not that much more expensive than a fully mapped pc3. Chips premapped for a specific exhaust are at best approximate do not take into account filter variations and other bike specific anomalies and will never match a properly set up bike, they are another "temporary" or interim tuning improvement. As far as your popping goes, if this is occurring whilst using the engine braking or on overrun it could simply be a leak at one of the exhaust joints. Air is drawn into the system through minor leaks and can cause slight secondary ignition of unburnt fuel in the pipes. Check you manifolds are not leaking. Alternatively poorly set up or unbalanced throttles can present similar issues.
It only really started when the race Termi's went on, but it's more the snatcy throttle I'd like smoothing. Thing is, 2 places have told me there is little that can be done on a 996, it's not like a 999 or above.
CR speak to someone who reflashes race/road bikes for a living and knows what he is talking about. IIRC you have a 1.6M ecu similar to my 748, no issues reflashing it CJS RACING Motorcycle Dyno Tuning Ducati & Superbikes Bristol ECU Custom Mapping
I have been unhappy with the state of tune on my 996s. I am ditching the PC3 and moving on to the PCV so I can fit auto tune AT300 kit I already have the PCV as it came off an old race bike (996 as the map Info tells me) I'll update as I get it done in a month or so
To my knowledge, CJS is currently the only person still offering to write an EEPROM which is then used to flash the EPROM. I spent months trying to find someone who still had the software and an old PC to run it as it is very old technology. Forget Ultimap as that too appears to be obsolete. If you can find a good base EPROM, the PC3 then has less work to do. My 853 has a 748RS EPROM and the PC3 tidied the fuel/air ratio. Final figures are 133hp and just shy of 70lbf and the through throttle opening delivery is very smooth and linear. I'm chuffed to bits with what was done. Andy
Chris is very difficult to contact by phone. Either try and catch him in person at work or e-mail him. I do not think he works regular hours due to other commitments. Andy
Sounds good my 996s was pushing 127 about 2 years ago, but seems to have gone off song a little so I'm going to get the Tps and syncro done. BeFaster in Hannover can do the EEPROM work as far as I know
