C10 EFI Project
« on: January 05, 2020, 05:29:29 pm »
This was supposed to be a bike for my wife's trike but things changed.

Its taken a while to finally get this to the point that it ready to tune. I have had so many interruptions and family emergencies that took priority away from this project. I had this built and running for quite a while but am just in the last month giving it the attention that it needs to move toward a bike I can actually ride.
The hardware is complete and working.

Now time for tuning.  One  of the problems I have with tuning is that there is not enough vacuum variations between full Idle and wide open throttle. So I need to generate a new  AFR and VE tables that are scaled to match the MAP in the motor.

 I have finished tuning the idle tables and it seems to like the settings at 1000 RPM. I will need to re-tune idle after I have made the new tables.  Lot of work to be done on other throttle/load conditions. Wish i had a dyno in the garage cause I am not going riding in the middle of winter.

Here are some clips of it's progress.  https://youtu.be/aClwRT8BqTw

The only one I know of that has EFI-ed the C10 is Rev Ryder.
He EFI-ed his due to the fitment of a Turbo.
Chuck is I believe still recovering from illness but seems to be active on the COG forum.

Sport Rider,  I don't have a kit per say. I have lists, drawings, and documentation about how I did it. I tried to keep it simple and don't do anything exotic that any one else would struggle with. I think the biggest hurdle in the whole project was fabricating a crank position sensor.  Everything else can either be purchased or easily fabricated by "most" weekend mechanics.

I've seen what you can do on your cafe racer and can say you wont have any problems replicating what I have done.

Getting the mechanics and electrical is done and behind me. Now comes the tuning part which I am not an expert. I have done one other project like this but the hardware design was much different.

I will show updates when it is working well enough and the weather is warm enough to go riding.
This video shows a bit of the good, the bad....PM me if you want to see the Ugly.

He is not the only one.  Mine is naturally aspirated, no turbo.

I think B.D.F. (Jim) has also converted a C10 to EFI. I got a lot of good advice from him when I started the EFI project last year on my Honda.

Meanwhile I am tossing my cheap Ebay Wide band controller and replacing it with one that I can trust. The one I have installed will read a certain AFR but lie to the ECU so that the ecu thinks the bike is running lean. I have verified this by scoping the output of the Wide band controller.  So I need to make a new harness for the new controller.

Also got the Cafe' Racer seat from China yesterday. It looks sweet when sitting on the bike by itself but looks  NOT sweet when you add the huge gas tank.  Not sure I'm going to be able to use it.

Playing with the used side panels.  I think it looks good with them. I also think I will paint the tank again to match the panels.

If it't not too cold tomorrow I am going to  take it for a test ride. See if I can make it a few miles without a catastrophe. Hope I don't have to push it home.

Looks stock, don't it?   But it ain't. When I am finished I will do a revealing walk around.

reveal your throttle body.
because I don't buy it.

 :loco: :loco: :loco: :loco:

I'm saying, reallly, this vid is not really telling me you have fuel injection...

ok
you win.
somehow the throttle position sensor was not showing any movement on you computer.
If you plan to ride, it's a heavy bike to push home... might want to decommission the air cut diaphragm valves on carb 1 & 4 also... as they are not functional anymore in this application.
have fun, ride safe,

please, no need to... I really have to be honest, and as a longtime tech savvy person, really dislike fake crap. Sorry.
reveal your throttle body.

I'm saying, really, this vid is not really telling me you have fuel injection... do you really take us all for fools?
 
Seriously, no. Not everyone is a fool. Just you!

You so often scrutinize others work. You disparage me again by calling me a fake. You imply that I am trying to fool everyone.

For someone like yourself, “a long time tech savvy person” I would have though you figured it out by now but I’m beginning to think you are the biggest fool here. 
You like to capture images, blow them up and point out “important” details that support your belief.

But for someone that pays such attention to details I am shocked that you have overlooked so many blaring clues in plain sight!

In the image you captured you are pointing right at the throttle bodies and the throttle position sensor.
