Last time I asked/looked MR didn't have a Dyno. They take the bikes to a Dyno house. Bit like a Crack house.
I read 'somewhere' ages ago that JHP could make specific maps for the 848/1098 etc that increased bhp etc quite dramatically. I was under the assumption that these were loaded onto the standard ecu but maybe I picked it up wrong and it could have been a Nemesis. It would be nice if there was other maps to have a play with using Ducatidiag other than the DP maps. Are Nemesis maps made using a different code to the Ducati ecu's ?
A Nemesis ECU is a replacement for the original ECU. The software is different, and requires individual mapping. Ducatidiag is hardware that allows changes to the chip on the original ECU and is not as configurable as a Nemesis. JHP do/did chips with DP maps on, still only a halfway house as each and every motor will have different AF requirements
Yes I have looked into the Nemesis ecu when I had my 1098 but they were quite expensive. Already have Ducatidiag and have tried the slip on and the full system maps but just wondered if there were any 'programmed' maps that were made up by JHP but was not sure if that could be done. It must have been the Nemesis maps that I read about, I recall someone saying that it felt like a different bike with much more power after having the specific map made for them. So Nemesis uses a different code to the Ducati ecu ?
The AFR of all the ECUs mate is like an image of the the Alps its so bad, not hard to improve even if the over all AFR was changed/mapped. The advantage of PCV over many of the others in mainly the mapping of the ECU is the interface, not only does it allow you to walk into any dyno center but you can also back up your own maps for safe keeping should the PCV fail, I am sure the dyno opp that maps your ECU will keep a backup but you still need to visit him to have it flashed back onto a new ECU should yours fail (not sure they give you a file that can be reloaded with the likes of ducatidiag), not that it would but you never know... When looking at the cost of mapping the ECU and PCV+Remap they come in around the same. Pros and Cons of each I know but as a dealer for DJ I am still a fan I like the idea of mapping the ECU but I also like to be able to remove it all with ease too should you want to sell etc, I guess most could just sell the ECU with the systems or just sell the bike as is, makes you wonder in time how many bikes will be around that have changed spec since mapping and now run a wild fuel map....
there are a few commercial products out there that allow various ECU's to be played with so theres lots of different companies offering this now, at the end of the day it comes down the competence of the tuner doing the work And for this reason CJS Ducati have a long list of advocates and satisfied customers which speaks volumes. but they are not the only game in town I have used BSD in peterborough are also very good tuners they used the Rexxer system on my magnetti marelli ECU and their dyno to set fuelling and ignition they also tune both cylinders they also changed rev limiter, torque limits and disabled the Lambda sensor map on my monsterc I dont know if they can do the newer seimens ECU's (whereas CJS definitely can), but its worth a call if they are more local to you. if they can work with your ECU then they will do a great job too one other thinng that BSD offier is that once you have had a bike setup by them, they can adjust again for just the cost of hourly dyno time. they also give you a usb drive with a backup of your old and new maps on that can be flashed back on request
So, some tuners can remap the Ducati ecu just like you would making a PCv map. Does this mean that if you have a copy of the map it can be loaded onto anyone elses ecu so they can try it on there bike to see if it makes any difference or do the tuners make it so they have to load it on themselves and you cannot just send the map to someone else to load using Ducatidiag ? Using the two DP maps ( slip on and Full system ) my bike runs very similar, maybe a little more responsive with the full system map. When using the slip on map those riding behind me say that the bike stinks of fuel, I thought that the full system map would be more likely to do that. Maybe just shows that they are just a generic map and suit some bikes more than others unlike a custom made map. I wouldn't mind trying a custom map if they could be loaded using Ducatidiag. Here in the NE there is no one that can remap an ecu, plenty of dyno centres but most of them I would not let loose on my bike if I got a PCv.
theres only one way of getting the fuelling correct for each individual bike and that is dyno time with said bike............anything else is just pissing in the wind!
Yeah never a good idea to share maps, if for example the dyno opp was to lean off a very rich cylinder and you then load said map onto an already lean bike you can be asking for trouble, if downloading maps from DJ that's a different matter as those maps have been checked to be sure they are on target, or in other words no big negative numbers. If your too far from a dyno then Autotune may be an option but you will need an understanding of the way it works, Ive covered it hundreds of time on the net but in short Autotune has its own fuel table that it builds based on the base table, the correction is limited to a factor of 20% (you could change) to be sure no damage is caused by faulty readings etc, you can then accept the values of the AT table once maxed out and then it will update the base table, you can then reset the AT table and have another 20% worth of correction, you keep doing this until the AT tables values level out. Not quite automatic at the start with no custom map but an option for those that have no access to a dyno.
Yea what Andy said there would be know point trying a custom map made for another bike because it might be bollocks even though its good on theirs
