Hi, thanks for the reply. I have just received an identically numbered ecu this morning. The last four digits printed in black are different, I assume these may be detail differences in the ecu as the number is not pre printed. I have a Haynes manual that I can look through for information on ecu's. I think you may have to disconnect the battery before swapping it out and go from there. I need to do this anyway just to check the back up ecu is working properly. Hopefully the Haynes manual will shed some light. Thanks again Steve

Hello, I've asked on the Legacy forum but thought this may be a better place to try. I'd like to carry a spare ECU that has been coded to the existing sytem so that if for any reason the 1st ECU fails I can swap it out and keep going. The ECU is from 1998 legacy number :- 8K 22611 AC840 A18-000 DJ5 7Y26 UNISIA JECS How complex is coding this to the existing system? Thanks in advance Steve

Thanks again, I'll give him a try. Steve

I would like to carry a spare ECU with me (the RAC don't recover watercraft apparently :) ) The engine is from a 1999 Legacy ECU code 22611 AC840 8K A18-000 DJ5 Unisia JECS How easy is it to recode or reset a replacement ECU (with the same part number) to allow plug and play should the first one become faulty? Thanks Steve

Thanks for the replies everyone. I'll pm tlag when he gets back from the states :) . I'm going out to where the craft is tonight to look for the engine code, ECU code etc. I want to get some spare components for the engine management system once I know what I need to get. Steve

Hello, This is my first post on here. I've recently bought a water craft that uses an EJ20 legacy engine, since I hope to have this craft for a while I need to get up to speed on the complete engine and fuel/ignition systems etc. Does anyone here think it is possible to convert the fuel supply system to single pipe with no return as used in more modern auto set ups? My aim is to reduce the number of pipes and connections involved in the fuel system that are in the engine bay and fit an in tank fuel pump with built in fuel regulator/sender etc. I appreciate this would not be normal practice but perhaps someone will know if this is possible. I'm still looking for the engine code on this motor, since it came from a replacement engine supplier with no vin I've been scotchbrighting around the block but no code yet. I've found the number 517639 on one flat near the edge of the block at the bellhousing end. The engine is an EG20 with red rocker tops and inlet manifold, non turbo. Thanks in advance for any help or advice on this. Steve H
