Engine Opel 1,4 16V NA, 4 cyl, firing order 1342, without modifications (except exhaust, manifold, air filter)
Car using stock coils, stock injectors, stock electronic throttle body Bosch.
ECU SerialNr:15160
Special features:
-Internal MAP 400kPa (planned conversion to turbo in future)
-ETC (with bridgeoutput interface)
PROBLEM:
Car was tuned a half year ago, run perfect, without problems, but since one day last week, customer had a problem with start.
After checking all data with PC, i found problem with internal MAP sensor.
MAP still show 5-10kPa even if the hose is disconnected from intake. I also try to make little over/under pressure with mouth, but MAP value did not change.
This is a screenshot of MAP value and MAP settings:
I think that the problem is in MAP sensor.
Please retest and repair ECU if necessary.
If you need any additional informations, please contact me.
Thank you.
