Inyection problem Ep3, I am hopeless!! PLEASE NEED HELP!!

Post by jorgek24 »

Hello.

I have a BIG problem with me car, I put especifications and them I explain problem:

- what vehicle you have: HONDA CIVIC TYPE R EP3 2002
- serial number of your K-Pro: 05001919
- version of software being used (from Help, About) i dont now, not understand question
- ECU part number (starts with 37820) and serial number (the number under the part number) 37820-PRA-E03 2030-400961
- KManager version (not 'the latest'): 3.3.1.0
- the calibration (as an attachment): i dont now, not understand
- a datalog of a problem (as an attachment): Not apear in datalog
- anything about the car which has been modified from stock which may affect the ECU (don't include what sort of rims you have nor stereo etc): manifolds, ttrote bodyes, inyectors 440cc, plx wideband in ELM port...
- when and where you got the K-Pro: new reciently buy car, i dont know when is buyed k-pro
- a specific description of the problem:

This is the problem.

To the inyectors wires, the signal that arrived is wrong, in ralenti(900rev/min) to the 1 and 3 inyector arrived 2 pulse of inyection (look osciloscope image) Image

and to the 2 and 4 inyector arrived 1 pulse of inyection (look osciloscope image) Image

I have probed to change engine wires(the harness from motor unit), exchange coils puting 1 cilinder in 2 cilinder(not change fail), exchange inyectors puting 1 cilinder inyector in 2 cilinder inyector(not change fail), I check directly ECU outputs of inyectors and from the ECU it goes wrong signal, them i deduced that the ecu is wrong, but I check with other ECU of a friend introducing me cartography map with kmanager, and the problem not disapear. Also I check me ECU in other EP3 and in other EP3 the ECU work well.
I check grounds, and i check also camshaft sensors changing for other engine, knock sensor I not change but I try to put not enabled in cartography map with kmanager, and problem not desapear.
I check also voltage of battery when alternator is chargin, 14,3V, is ok.

Only I have deduced, that something of the car, is misleading ECU, to ECU send this wrong signal to inyectors.

Them, I not know what can mislead ECU, to ECU send wrong this signal to inyectors, ANYONE KNOW IT CAN BE?? I AM HOPELESS!!

PLEASE!! NEED HELP!!!!!!!!

You have already determined it is not the ECU, so it must be something with the vehicle/wiring.
