Hi Guys, Can anyone tell me how difficult it would be to remove a Datatool immobiliser from my 748? I've never had a bike with one before, it just seems to be a pain...going off all the time. The chances of theft are very small here and the bike will be kept in a locked secure garage for 99%of the time. I know that some alarms are controlled by the ECU but being an after market system I assume that this one might be easier to remove than a factory one. Dave.
If it's a system 3 it's easy enough to replace the main board which is a much easier job than trying to remove the whole alarm. Failing that you will need to trace each wire and rejoin where it has been cut. It's not possible to get hold of the fitting instructions as Datatool won't provide them for security reasons.
Thanks for that, does that mean that I do not have to do anything with the ECU then? I am in the process of refitting the engine so it is easy to find all the splice points and remove the lot. Dave.
Hi Dave there are several threads on here covering this already which hopefully you can find using the search function alternatively google "datatool Ducati forum ".
Job done..I hope!!!! I have removed the DataTool completely, and resoldered the joints, the only sticking point was where 2 wires (Brown and White) connected to what I think was the fuel pump loom. I checked the wiring diagram and also this forum then soldered and heat-shrinked them together. I haven't run the bike yet as I still have a few other jobs to complete etc. so fingers crossed. Thanks to everyone who took the time to reply. Dave.
When I removed my datatool from my 916,most wires just unplugged.The only wires I had to reconnect,IIRC,were for the fuel pump.Hopefully yours is now sorted.
Excellent, i removed my datatool the other week also and it was a lot easier than I expected once I had undone the loom and could see all the black wires and where they cut in. Was a bit fiddly in places trying to solder the original ends of wires together, but managed it in the end. Then it was a bit of a tense moment starting the bike up for the first time in case it didnt start - but it fired up nicely. The actual alarm unit & wiring weighted 387grams too - so a nice weight saving!
Recently removed yet another datatool alarm from one of my bikes, this one was particuarly tricky as the fitter must have removed most of the main looms wrapping to hide the wiring, must have taken an age. I had to cut and unwrap miles of tape to trace back the wires, took me many hours. I did however find via extensive Googling that if you remove the alarms top cover and bridge terminals 1&2, and 5&6 this deactivates the alarm. Might be worth considering for someone thinking of removing the alarm as it's driving them mad, but doesn't want to remove the alarm.
Finally got my 748 assembled after stripping and painting the engine and also removing the Datatool immobiliser. The clutch slave cylinder was also leaking So I replaced it with one from a Monster, to help compensate for the different push rod length I put a 8mm ball bearing inside the slave.....I have a problem selecting neutral now as the clutch is not quite clearing enough. Does anyone have a solution? Dave,
ingenious idea with the ballbearing Dave but the difference between the two pushrods is 10mm and that lack of 2mm will make a difference. If you view your slave as a serviceable item and/or if it's already quite old then you could look at taking 2 mm off the mounting face as a crude solution. When you look at the clutch plates while pulling in the lever, how much do you reckon the pressure plate is moving? You need around 2 to 2.5 mm for a clean disengagement depending on a few factors.
Thanks Chris I'll maybe have a rummage in the garage and see if I can find an old 8mm valve stem that I could cut down to 10mm, it does not need much more travel to find neutral. Dave.
You can disable one with a paper clip, i disabled mine on my old bike, ran that for few weeks and took it to bike shop to have it cut out properly, was £40 to get it removed, if you want to disable it just use google, easy really!
i have a system three which has given up the ghost after nigh on 15 years faithful service, where may i ask did you get a new main bird from, ta.?
I got mine from eBay for £10 but also bought one complete alarm cut out of a a GSXR Suzuki for £15. The main board is very easy to get out and can be replaced in situ as long as you can get to the main box it is below the siren.
The difficulty in getting rid of a Datatool depends entirely on how well it was fitted. I binned one from a mates Honda Dull-ville a while ago and it took about half an hour - but then it had been fitted by a complete chimp. Properly hidden and connected wiring makes life more difficult. What did surprise me was how physically tough the actual unit was : it started making a noise as soon as we took the power off it - internal battery was obviously fully charged - so we chucked it in a bucket of water with a brick on top of it. After refitting all the bodywork the damn thing was still bleeping away so we took it out and hit it with a sledge hammer - first hit shattered the box into hundreds of pieces but it didn't stop it making a noise ! Second hit wrecked it... The reason we took it off was bascially that the remotes were knackered, not the unit on the bike, and the bike was fitted with HISS as well, so it was pretty much redundant. It had been working fine for many years - unlike the garbage Meta alarm originally fitted to my ST4 : they are shockingly unreliable. I also ditched the Datatool from my ST4 recently - once again because the remotes were trashed - and that wasn't difficult either. That was made easier by the fact that I knew where all the wiring went because I had found it all previously and soldered all the joints that the dealer had originally made with Scotchlocks - there's no wonder Motorcycle City went bust !
