Default Cosmo's ECM Relocation Mod

Well boys and girls....I must say I am very excited on my new find. As some of you may know from my other thread, I am in the process of tearing down, rewiring and rebuilding my 07' 1200N (http://xlforum.net/forums/s...d.php?t=466630). One of my goals is to run an 06' rear fender with a 06' Lepera Bare Bones seat. In order to do this I have to relocate the dreaded ECM.

Well I think I have the answer many might be waiting for 07'+ sporty's. I thought of a few places to put the ECM....like place it in a weatherproof box and mount it under the tranny between the frame rails or above the tranny above the starter. The more I looked at the bike with the motor installed and the position of the ECM above the starter it kinda defeated my purpose of rewiring the bike and keeping the area clear around the engine.

Someone else had placed the ECM under the battery cover, but what I didn't like was the fact that the cover would not close like it normally did and it stuck out further than the oil cover side. So I started playing around. I was getting interference between the battery cover and the mounted ECM. So I decided to modify the ECM. I cut two of the mounting posts off so that I could suck the ECM up under the lip of the oil tank. This helped a lot. I was only about 1/8-1/4" off from being back to normal.

So I pondered the situation...pulling the battery in and out...and the battery tray...the ECM...closing and opening the battery cover atleast a hundred times. Then it hit me. The battery! On the throttle side of the bike it is captured by the oil tank BUT the battery tray itself keeps the battery from hitting the tank. I pulled out the battery tray and cut the back strap and side off:





Here is a pic of the battery in the tray and you can see now it can slide past the edge:


My plan is to make a new strap that will hold both the battery and ECM to the tray. Here is a picture of the modified ECM. You can see the 2 mounting posts that I cut off and the fins that I removed:



Here are some pics of the battery and ECM taped together while I was doing the "fitting". You can see why I cut off the mounting posts on the ECM better here to allow me to move it up as far as possible under the oil tank and the fins and bottom posts for clearance to the battery cover:


Here are some pics of the cover closed....looks like it did when I first bought it:






Maybe it is just me but I am super excited about this. I know now that I can keep the entire area around my engine as clean as possible. What do you think???

Great job. That's good thinking. I've been thinking on this for a while now, trying to figure out how to get it down there without having the cover stick out. You've got the solution. Thanks for doing all the heavy thinking!

Thanks guys....appreciate it.

It just dawned on me though....I've relocated my fuse blocks and crap that currently sits under the battery cover....so I wonder if this would work with the stock 07' wiring set-up? I think it is far enough back that it would clear the fuse blocks.

My excitement is that this was a big hold up on finishing up my wiring to the ECM/fuse blocks/TSM. I am also running a V&H Fuel Pak...from what I see I have a couple options for mounting it (would have more if I didn't relocate my ignition switch where I did...but I prefer my new ignition switch location) so it is just a matter of finalizing that and getting closer to getting the bike back on the road!

Will there be any issues with heat? Will you still have some airflow in there by the oil tank?

Maybe a slot in the cover with some cool mesh?

Russ, yeah air flow around the oil tank was a concern but after I made the mod the only part of the battery actually touching the oil tank is the upper edge. There is about 1/8" clearance just below that top rim of the battery and then it opens up as you go down to the bottom of the battery to I would say 1/4" or a little more.

Edit:
Just thought of something else, I have removed the large plastic piece that goes around the frame just in front of the battery (holds some wires, fuse blocks, etc) and the wires so I have essentially increased air flow to behind the oil tank cover.

You can see what I was talking about as far as it touching just at the top of the battery and the clearance between the battery and oil tank. It doesn't look like it touches from this angle, but the lip you see on the oil tank slants towards the ground as you go further to the back of the bike.

The only wire I'll have coming through here will be the negative wire coming from the negative lug on the battery that you can see in the pic. So I should have an increase in air-flow through this area.
