To date they have tried 3 solutions:
swapping out the oxygen sensors for known good ones - didn't work;
cleaning the 'gum' out of the throttle bodies - no difference;
installing a new version of the ECU 'firmware' - some improvement but still not as smooth and free running as I'd like.

My next step was going to be to buy a PC. My local dyno guy says he can do a map for each cylinder, which sounds like what is needed if the hex head motor is, in fact, fuelled and sparked like 2 engines.
That's what the ECU does, but it isn't how it should be. If you get a PC, tune both cylinders the same.

Poolside, you mention that the CAN BUS version of your 'solutions' are further down the track. Like how far?
We're developing the device for the 1200 CANbus over the winter, and it should be ready for spring. Maybe sooner.

The first product, the one we're working on now, is designed to improve the low RPM symptoms you described, on the 1100/1150/1200. It will be finished in about three weeks. When that happens we'll put up a thread in the Vendors forum.

You're having problems with a lumpy idle too? A device for that is also scheduled. It may get slotted in over the winter.

The development work for all the devices will be posted here. In a few days I should have a production example of the first product in hand.

At that time I'll post up a description of the products, and a timeline for development.
