The advantage is my 998R gets its Nemesis back which means I can then replace the MT940B dash with a standard 1098 dash and then my 955 gains the MT940B dash, so a double benifit.

The Scitsu on my Yellow and Blue bike does and as it's direct powered it doesn't even need charging

Bike now starting easily and running quite sweetly using the 749 ECU and Dash along with a PF1C Linear TPS and the 1098 modified Loom :)

Not sure why but on one of the 749 ECUs I tried it keeps dropping out the rear cylyinder dispite it being the same ECU hardware build and same program loaded.
Checked the readings of the coil drivers and they are both fine on the multimeter, so a bit more investigation to do there. But as mentioned its running well on the other 749 ECU

Spoke to soon, After having the bike running sweatly on Sunday, I removed the dash and ECU as they weren't actually bolted to the bike, just connected to their wiring.
So next day I Bolted on the ECU and reattached the clocks and low behold the bikes back on one cylinder this time running on the rear cyl only.

To me its looking like an earthing issue somewhere dispite already having a earth wire straight from the battery -Ve to the ECU heatsink

Will have to see if I can find the problem this morning

I've just read the whole of this thread and understood nothing !:o

However, I'm sure you should be going pro with this knowledge !

Got to admit Mark it's testing my understanding

Fitted an extra earth and hey presto bike running sweetly on two cylinders, warm it up and the turn it off. Then it was reluctant to start and when it did it was back on one cylinder.
Tried different HT leads and then coils, even swapping to the later type found on Multi 620s and alike, still no joy
Connected up spare ECU and attached a flying earth lead, now back running on two cyls. Decided to replace the Nemeseis Heatsink and use a standard one as this provides a better earth connection, with this swapped I fitted the ECU that had just been running it on both cylinders and now its back to running just on the rear cylinder.

Juts been checking Oil Temp ignition correction figures and injection phase and a few other parameters and they all seem as they should be.

Back to work tomorrow so will have to wait until Saturday before I look at it again, hopefully by then I will have had a few more ideas on what I can try to solve the problem.

Nope, replaced on day one and has been fine since then.

Use the formula: (TFC/2)=Ans usually works


Tooo fkin clever by half. :D :frog:

Interesting stuff Kev. Break in the wiring somewhere I reckon - based on it working fine until you pulled it apart & reassembled it. Assume you've 'waggled' whilst it's running ;)

Good luck mate, don't you just love vehicle electronics.

I would be tempted to check all earths connections are un-coroded and tight.

It's not fuelling is it? blockage etc. **** in the tank !
