Got the 205 back together running low boost sc, with a normal gti6 ecu the fuel pump primes and stops, but with the low boost ecu it's continuous?

Why would that happen?

Car runs and ticks over ok with both ecu's

Is it actually continuous or just on for a long time (30-ish) seconds, and have you repeated the test?

The ECU does prime the pump for longer if it's been unplugged for more than a few minutes, so that's a possibility if the standard ECU was pulled directly out of a car to test with.

Both ecu's have be sat in garage for months, put normal on just incase I blew it up, it primed for 5-10 seconds then stopped, started car, ticked over

Then shut down, put lb ecu on and primed continuous
