Hi everyone,

i have two 90HP E-Tec's, one from 2005 and one from 2006. The 2005' one had a broken EMM, which was replaced by a used one from a 75HP engine (no other EMM could be found).

My question: as a direct installation of the 90HP software on the 75HP EMM seems to be impossible, is it possible to transfer the data of the working 90HP EMM to the 75HP EMM?

I want to use the EMM from the 90HP 2006 engine as "donor" in Evdiag, and transfer it's data to the used 75HP EMM. Is this possible? Will the 90HP map files be loaded onto the 75HP EMM? I don't care when serial numbers don't match afterwards, or the run times are incorrect. I just want another 90HP EMM.

Thanks for your help!

If EMM is part number  0586759, it can be done by dealer with access to Bossweb password.

Preferably with EFD from damaged EMM.

Thanks Norman and yes, part number on the EMM is 586759.

The old 90HP EMM from the 2005 engine is completely dead, not able to connect to EVdiag, no lights, no sound.

So no chance without having the "password of the day"?

I think it can be done with the "data memory x fer" function.
. But you will have to update the info for the injectors afterwards.

Try to disconnect the J-2 (Lower connector) off the 'dead' EMM. If it is an internal short, it may turn on and let you collect the engine report and file.

Rick, I know about the 'Memory X fer' function, but have to admit I never tried it. [thumb]

Thanks Nordman. It's been 6 months since I've programmed a used EMM so not fresh in my old memory.
As I recall, a new EMM that is loaded with "coldtest" has to be programmed through "prep new EMM with the password of the day. Before memory x-fer was available we used to have to start the prep EMM process on used EMMs then interupt the process once coldtest was loaded. I'm fairly sure that x-fer works only on used EMMs.

Thanks Rick and Nordman for this information.

When the memory transfer works, the 75HP EMM will receive all the data of the 90HP EMM, including map files.

The 90HP donor EMM is loaded with the "special" firmware which came with the oil-pump upgrade (Evinrude part number 5007477). The other 90HP still has the old oil pump. Is it possible to downgrade the software after the data transfer to the "regular" 90HP software, which is used without the upgraded oil pump?

The "oil pump update" basically just eliminated the oil pressure switch on the pump assembly. Last week I had an original oil pump with a bad sensor setting a no oil code. I installed the oil pump update program and cut the wire going to the pressure switch. The new software may just ignore any signals from the pressure switch but I did not try that. Cutting the pressure sensor wire did work.

Rick,

that's EXCACTLY what i thought about the "new style" oil pump. Some time ago, i analyzed this pump a little bit closer.

The wire, which was formerly connected to the oil pressure switch (which is not present anymore on the new style pump) is just connected to a diode, the other side of this diode is connected to ground. All this is wrapped into black shrinking tube, so not visible.

But i thought there MIGHT be a difference in the solenoid, maybe different oil output rates per pulse etc.

When this is really the only difference between the new and the old style pump, Evinrude is charging a lot of $$$ (€€€ in my case) for something that could be fixed for 0$ (0€). The kit which contains the new pump costs 600,00$ (or almost 800,00€ over here).
