is anybody able to give any feedback after having there bikes remapped by cjs? im particularly interested if the bike was done with the standard exhaust? chris disabled the o2 sensors on my bike and that was a great success for me, now thinking about going the whole hog and getting the full remap done, lots of dosh but is it worth it? more power, smoother, economy/range etc. your thoughts/experience?
I'd be interested to read more about this too. What are the advantages of disconnecting the O2 sensor? Pete
hi, pete the advantage of disabling the o2 sensors and how it makes the bike run, are the bike will run below 3000rpm without feeling rough. not an issue if you are riding quickly, but my bike was almost unrideable in town with slow moving trafic or if i just wanted to bimble around. now the bike is fine, with no hesitation down as low as 2250rpm, bike now feels like it should do!
Thanks Jonnyboy. Do you have the new 1200 or like me, the classic? Once the sensor is disconnected, is there anything else that needs to be done or is it a case of just unplug and go? Pete
i have the 1200 not sure how this would apply to the classic! for info chris mods the ecu to disable the error message you get when you disconect the lambda sensors.
Will this blow your warranty though? Wouldn't it just be easier to fit FatDucs so they can be removed before a service?
1200S I have the FAT-DUCS fitted with the stock silencer. The latest fuelling map still leaves a small measure of hesitation at low revs and they completely fix that by fooling the oxygen sensors without causing error readings on the dash so what more do you need. Yes, you can easily remove them for any warranty issue or in the unlikely event that they cause a problem or fail. Just unplug the connectors and connect the original plugs back together. They are not cheap but way cheaper and less bother than a full custom re-map. Of course, if you have a modified exhaust or silencer, a full re-map may be the only answer. One VERY IMPORTANT issue with the expense of a custom re-map is that there is no way of locking it on the ECU. If a dealer servicing the bike decides or is told by Ducati to load a revised fuelling map, your custom map is lost. A long shot maybe but a bummer if it happens. As for the warranty, who knows with Ducati - they, or their dealers, come up with some crazy rulings. Take the claim that the warranty is void if you fitted the uprated rear spring supplied by Ohlins not Ducati. Same spring, same part number and probably not defensible in law but do you need the hassle?
The only down side of a remapped ecu is if you change something on the bike like filters or pipe you'll have to remap again and its not cheap. I know the PCIII map is not as good but a remap is a fraction of the price and atleast with a PCIII you have a physical item you can sell seperate from the bike if needs be. Ideally I would have wanted a PCV with autotune but they dont do it for the 999
Is there any way, short of taking the bike to a dealer, to find out which map is loaded onto the ECU ?. A combination of buttons together with key off etc perhaps ? (as I have seen on some cars). The reason I am interested is that my (early 2010) Multi was bought second hand (Jan 12), with it's last dealer visit (7500 service) being in September 2011. The previous owner did not seem to be the sort to make sure the maps were up to date and I'm not at all sure that the dealer in question is likely to have been very proactive. I am tempted down the FAT-DUCS route but want to make sure I have the latest maps, is there a version number for the most recent map ?. The bike runs fairly well, but is a little rough low down, and has stalled 4-5 times (in 1000 miles) on me when down-shifting for islands despite my habit of blipping the throttle (ridden too many old Brits in my time !). It also seems to hold tickover very high when restarted, even when hot, for a few minutes. All of which makes me think I'm running on a fairy old map. All thoughts appreciated
Its sounds to me like you may not have the most recent ECU update, as this was a fix for lumpy low down fueling and occasional stalling...? Im not aware of anyway apart from a dealer visit to tell if you have the latest version or not, however a lot of dealers did the ECU and a dash update at the same time. And you can tell if you have the latest dash update by holding down the red button when you switch off and see if you get a warning on your dash. I fitted the Fat Duc's on mine and it greatly improved the low down rough running, i have now sinced gone the whole hog and had a custom remap as iam running a decat QD exhaust system with K and N filter, i now have no fueling issues and the bike goes like stink! Not that it didnt go badly before.. But now smoother and even better!!
If only someone would come up with a Ducati equivalent of the brilliant GS-911 BMW diagnostic tool! Home — Hex code
Andy - yep anything to aid home diags would be a great help. We use "ecu spy" on the Buells, it's free apart from having to make a cable up and essential in keeping those tractors running sweet. Equivalent for the Ducs would be very helpful. Boomer - Thanks for the tip on the the dash warning light, just tried it and no warning light to be seen !. Looks like I am a few releases of code down. I'll book the old girl into Coventry and see what they can see. Looks like I need to ask them to check on revisions of code on ECU & Dash. I'd be interested to see if there are newer releases for ABS and DSC as well, after all mine must be fairy early in the production run !. Just hoping Ducati Coventry prove to be interested and helpful.
At which point you pop back to Chris and he reloads your map for you. It's all recorded, plus he notes which map is yours on the back of your paperwork. Not exactly the end of the world As I recall, the spring claim hails from the US, the land of litigation. There's enough DES failures on the standard springs as it is :biggrin:
I think that Chris has a postal service so you can send your ecu and he will remap to the engine management you had, this would negate the need to travel for those that distance is an issue.
Been reading this thread with interest. Is there much or and difference between getting my bike mapped with a p/c or remapping the bikes ecu? Mine has the racing ecu and can be mapped but wondered if one ways a lot better then the other.
Termi and stock ECU's can be remapped...........in fact the so called Termi 'Race' ECU is just a remapped stock ECU! 'Race' ECU on the right Stacks apparently, a custom remap on the Dyno by someone like Chris at CJS is way better and you get the benefit of O2 sensors disabled with no dash error and other tweaks....but I'll let someone who's had it done elaborate. Of course it costs a bit more, but again, all the feedback I've read says the CJS service is worth every penny. On the other hand the benefit of the PCV route is that you can flog it on as and when the bike sells and get some money back.....I'm not sure what if any premium you'd get on the selling price of a bike that'd been CJS'd. PCV is only as good as the setup, ideally you still need Dyno runs and an expert on the job to make the most of it. On the subject of custom maps being over written by Dealers.........when the bike goes in for services just tell them that under no circumstances should the ECU be flashed with any engine management/fuelling updates ;-) I do this for my Termi 'race' ECU which still has the original 2010 mapping as my bike runs pretty good and I didn't like the apparent 'side effects' reported that resulted from later maps.
Interesting - I wasn't aware they could do this. I know the software changed about a year ago to allow them to see what changes were made, as this allowed them to diagnose that my Termi ECU wasn't taking the updates - up until then it was just plug it in, press go and wait for the "bing" to say it's done. That said, it's only been since Feb that I would have been interested anyway :biggrin:
The software updates have always come in 'packages' as far as I know i.e. Engine management ECU udates, ABS ECU updates, 'Dash' ECU updates etc so Dealers can select which to apply. I don't know that much about this, would be nice to have a Dealer or two onboard here and spill a few trade secrets
