I’m very close to getting the Zed ready for its manual conversion, but there’s a few things I’m not sure about. I intend on getting the manual kit off Bonsai Breakers, so hopefully I’ll get everything needed. Unless anyone on here has one?

1. Do I need a different ECU for a manual?

2. Do I remove the auto ecu or leave it?

3. The blue relay behind the wing I hear it is bridged together again do I remove the blue relay?

4. I’m sure my zed has a 1 piece prop, I’m guessing I will need a whole manual prop?

5. Does anything need setting up electronically once done?

 

any pointers and advice you think I’ve missed would be great

1. No you dont need a different ECU for the manual.

2. Just leave it it will work fine.

3. You can get a bridge cable from Wiring Specialties or just bridge the cable. (or make a secret switch for an anti theft system) 

4. You will need a new prop as they are different sizes.

5. You will need to run a ground wire from the gearbox to ECU Pin 44 for the Neutral Switch, easy way i do this is chop the plug off or find

a spare plug, ground one side of the plug to the gearbox and run the other side to pin 44.

 

Thanks for the help. I’m just weighing up the involvement in doing it, as I was going to send it to jimmer (but a long way away from me), there is a gearbox specialist by me who I have to fit gas boiler &  heating for, so we were going to trade work. He’s not worried about the physical side as he has worked on Z gearboxes before but he does have reservations about the electric side involved. Just not sure what to do?
