hello,i've just chipped an p28 and when i put the jumper it doesn't take the map and the check engine light stays on,other strange thing is when i take out the jumper to run the stock map,when i put the ignition on the check engine does a quick blink,not like it should do with a stock ecu.i've tried with other chipped ecu and it works.

double checked it ...desoldered and soldered again..still the same problem.
