stu did do some, using a board that he was supplied by SECS, but he hasn't been able to get anymore for months and has been badly let down by SECS.

it is possible to have your ecu converted and the code added to your chip by RP Lab in Germany, which is better than the SECS conversion as it doesn't use a separate board that could fail and actually charges both coils simultaneously.

it's not mentioned yet on the website, but email them directly for a cost.

whilst it's there, you could also have closed loop fuelling added to your chip
