GSX-R750 K4-K5 - got a spare ECU, where do I start?


Hi,

I got a spare stock ECU. I have yet to test it, but it's supposed to be in working order.


ECU


My GSX-R is a track day only bike and I don't race in any official class. Basically I'd like to be able to re-map, but some additional features like quick shift would be quite nice too.

Plan A would be to 'hack' the spare ECU and use that. I know this will take a lot of work, time and especially knowledge. Knowledge, I don't have...

Plan B would be to use only the 'connector' part of the stock unit and use Megasquirt or VEMS.

Since I can always go to plan B if plan A fails, I'd like to give that a shot first.

Is there a tutorial, or a how-to or something to get me started?

As in - where and how to cut open the ECU, what wires, cables and software to use to read the memory off the ECU, etc.

Thanks, D.

I checked the ECU this morning and it works.

I got it open and I'm pretty sure it doesn't work anymore, as a couple of electrolytic capacitors and the quartz crystal detached from the circuit board in the process.

Anyway, I got to the big chip and it's hardly visible number. I took a couple of closeup shots:

chip-number2.jpg

From these photos I'd say the label says '64F7052' + a letter, that could be either a 'P', 'R' or an 'F'. Since Google didn't find any '64F7052' with a 'P' or an 'R', I guess it has to be an 'F'.

Now I have to get some 'Methylene Chloride' to clean it all up and to resolder the missing components.
