Dr Drift, yeah I have a source for this.
The problem is that the daughterboard on it's own is useless unless you have the address table, K-constant, speed limiter, rev limiter etc. as it means you would need to spend some time discoverying all this.
Which is why I am organising a group buy, so the cost of the address table info is split amongst us.
Dan, for some weird reason I was told it does not work on the N/A ecu's. But if you are willing to try....
