View Full Version : Help please - Rev counter on 1098?
Looking to add an aftermarket rev counter to 1098 to get thru' noise testing since my clocks have stopped working.
What's the best way to do this & what type of rev counter do I need? Doesn't need to be a long term fix.

Depending on ECU,
916/748
900/750SSie
Elliot
Spa
Scitsu
Stack
Some you have to configure to get the right reading on a twin
ECU is 5AM2 I believe. Any idea which is the TACH wire from ECU to clocks or would I tie in to the coil wire?

The Standard Dash gets the Tacho signal via the CAN line so little you can do with that, Standard dash must be working in some form otherwise fueling would be a bit off.
Are you intending to add another Tacho alongside the standard unit, something like a Stack or Spa unit will pickup off the coil trigger wire
I've broken the dash display in a crash & the rev counter doesn't display. I was looking to leave the existing dash on until I got a new one & have a separate rev counter for noise testing purposes only.
I have a 2nd hand dash hopefully turning up on friday which has had the IMMO removed to work with a nemasis ecu but I wasn't sure whether that would work with my ECU without IMMO being disabled on ECU.
Eventually I will get the dash and/or ecu sent off & paired but this quick fix was just to get me out this weekend.
There is no immo in the 1098 ECU, it is all in the dash.

Chris, I know you told me this before & I'm hoping your right but I've seen conflicting info on this so was trying to hedge my bets.
The ECU's in the 1098 (plus other later bikes) are completely virgin and never been coded. If someone takes your money to remove the immo then they are ripping you off.
Here's a screen shot off my 1198S ECU showing it is Virgin and uncoded (same applies to the 1098/848/SF and HM)

Nemesis ECU will work happily even if the clocks are coded as it ignores the IMMO part so i'm a bit worried when you say the dash has been decoded to work with a Nemesis as its not a requirement.
So far I have fitted 1098 Nemesis ECUs to two Desmo Due race bikes along with stripped down looms and 2nd hand dashes from a 1098.
if you have had the IMMO removed from the replacement dash then I would have thought the standard ECU would be OK. Bit like fitting the Virgin ECU on my 620 a couple of years back, providing a standard dash was fitted it would run with or without the clocks being coded providing the coded ones (IMMO function operating) had the the keys transponder to read from.
I may be wrong here but as far as I know a Virgin ECU is not the same as a ECU with the IMMO off, its just NOT yet been coded but still requires a signal from clocks

I have one of these handy little things, without the 3 stage bit just a single shift LED

They not only display revs in a digital display but it also provides a shiftlight that you can set to where you want it and is also compact
I have run your problem past JP (the creator of Ducatidiag) and he says you will be OK so long as the dash is uncoded.
I suppose I'll find out tomorrow. Don't fully understand the need to get rid of IMMO to work with Nemesis ECU but that's what the man off ebay said. Maybe he's been conned into paying to de-IMMO his clock.
Already had a couple of offers to remove IMMO from ECU.
If it doesn't work I just miss out on doing Croft this Saturday & send my clock off to scorpio. or try & get ducatidiag to work & use that as rev counter.
I suppose as long as I use enough tank tape around the laptop it'll be OK!
The IMMO function has not been removed from the dash. That answers that Q of why you would need to remove it when using a Nemesis ECU.
Unless I can get Ducatidiag working enough to show the rev counter I looks like Croft is off tomorrow. Hopefully I can flog my space.
I'll get my 2 dashes sent off to Scorpio beginning of next week & see how quick he turns it around.
Thanks for assistance.

Bummer, but what I thought would be the case, maybe you should be asking for some of your money back if they were sold as having the IMMO turned off.
Ducatidiag shouldn't be a problem, I've done the lead for mine so it picks up the power off the 2-way amphenol Superseal Auxilary socket, saves having to try and find somewhere to connect the croc clips to
Ducatidiag crashes everytime i turn the engine on. very very occasionally it has actually worked but 9 times out of 10 it fails.
Resigning myself to missing Croft - shouldn't have fallen off at Donny!!!!

The solution for this is to use a USB hub. There is a post on the Ducatidiag forum about it.
Tried using a hub before & different computers without much sucess.
Tried again, downloaded latest KKL drivers, run as XP compatible & as admin.
Connected to check to see if it works, disconnected then started bike & connect again. After a bit of fiddling & a couple of 'not responding' finally got it to work reasonably consistently.
Just have to hope Croft noise man accepts the laptop rev counter, can't see why he won't & that DD working tonight wasn't a fluke.
Hoping for fine weather now.
New & existing clocks have been returned from Scorpio electronics after being cloned. New clock now has same mileage as existing & bike turns over with new clock in place using the existing keys.
Bike can’t be started yet as the petrol tank is not connected but fairly sure the IMMO affected the starter circuit so think this is a result.
