A totally uneducated guess here....perhaps it's a modified performance ECU that can be fine tuned via a laptop?

Read it in a magazine once....I think Confused

thanks rod

the original ecu cradle has been removed for convenience of making adjustments and swapping ecu's.

i dished mine likewise for the same reasons.

it'll come to no harm providing it does not get wet fron a screen leak so wrap it up well and make sure its padded above and below.

I've seen some modified Lucas 4CU ECUs with an external
potentiometer on a flying lead, which plugs into the ECU.
Would allow for economy/performance adjustments on the
go.
