RT Racing ecu Standard fit in S4?

[magpies]

Just wondering why we have a S4C with this ecu.

Is the running as a de-catted car? with the ECU modified for timing. A@

It has ran with no cats at some point with previous owner - has cats these days

Then there is a link wire mod inside to change base timing. I supplied one for Richard back when, after decatting a car, might be that one. A@
