Thanks Troll, I was at the dealer today and the second hand ECU had come in from the US - if took 4 days! So they are going to fit it anyway but if the issue isn't solved at least I know where to look next.
The dealer also told me today the chrome Indian air filter cover fitted to it has a homemade air filter inside. He said it's a really poor effort at an air filter so they've ordered me a K&N filter for the corresponding Indian. They are an Indian dealer.
I'll keep you posted. Thanks again.

I'd bet on the AIT sensor being the problem, or the 2 wires from it, before I'd condemn the ECU. On the back side of the r/h airbox is a brass sensor with a black plastic connector. The sensor is inside the airbox, where it can get air flow over it. The two wires go to the ECU. I spent 40+ years in the automotive repair industry. This is the same as almost all the early EFI systems that were installed on cars, as far back as 1966. This is not special, it's actually a very simple system. There is no lambda sensor, and MAF sensor, just a mapped ECU program that has a cell for each expected situation.

Hi all, me here again!
So my FI light is going off when I start the bike and then comes on for quite a while when riding. It will go off for a bit then comes on again. As I bought it from a dealer I've got some warranty on it. They've plugged it in and its fault 13 (I think). They said they ECU isn't reading the air temp sensor.  The bike didn't run quite as smoothly when the light was on. They said it will run at default and that's why I can tell the difference.  They are going to replace the ECU. A new one is ?1k from Kawasaki so they'll be getting a tested 2nd hand one from the US.
My concern is what happens if it doesn't fix the issue? At the moment I've only had the bike a very short time so they will give me a refund - they are saying they can't guarantee it'll fix it.
By the time they get the replacement ECU, it'll be another 6 weeks on and as I'll have been riding the bike and either modified the stock exhaust or got new ones made, I'd hate to find they can't fix the problem.
What do you guys think?
