if the pump is not running it's some other issue. they always run the pump i'm sure.

Is this one of those ST4S’s that have the extra immobiliser box?

Yes

it's for different cams that make more power. as inappropriate as any of the others.

998 engine is totally different, but the ecu pin outs are also different. it simply won't work.

I tried the 2218p014 bike runs much smoother and works better than the oem. Need some warmer weather to test it fully, but very positive after short road test.
