That could be a strategy in the ECU dealing with a dodgy sensor. Not sure of anyone in your vicinity, but you could try Harvey Gibbs 01733 576614, Ahmed Bayjoo, Stu@MSD (they've all mapped Pectel ECU's to my knowledge), or finally Pectel themselves, for advice.

EDIT TO ADD:

Depending on ECU, it may also have logged what it thinks is wrong.
