Logging

As I mentioned earlier I can log the EFI system with a PC and not just standing still.
I can also "autotune" while driving.
Not so challenging task in a car but on a bike there's another matter.
I made a mount on the tank where I mount my PC, a 10" mini laptop.
The mount is made with a special Velcro® and have three mounting points.
Started with two but I added another for more rigidity after a while.
It's just a 10" laptop, but there is still a challenge but that's a part of the thrill.
I started with a "regular" laptop but that one decided to crash just before the first start.
This resulted in the project went to full blown computer project due to the fact that all EFI files was on that computer. So I had to shift focus and try to get those files out.
I had success with the file rescue and a search for another laptop begun.
The first one was kindly donated by my friend Wiking Cycles and he rescued me again with the mini laptop I have now.

Second start

The first start made my adrenaline flow so extreme so I completely forgot about logging the EFI system.
The next day it was time for another try, this time with adrenaline at more normal level.
By judging of the massive smoke it was a bit left until I could hit the road.
This solid cloud was the result of about just a minute of idling.
But this time I got a log so facts could been seen and relevant changes made.


Bling

Some bling was required when the EFI made the mighty old shovel roar again.
Ladies and gentlemen, the Bombus Speedshop point cover.


First start

So finally the D day was up!
(Actually a while ago, in middle of April.)
I was so stressed so there was no thoughts whatsoever to film this moment.
But all thanks to my wingman Feeler Cycles this super stressed and confusing moment went in to eternity.
This moment is definitely on my top 10 adrenaline list.
But even if the engine went rough to say the least this first time my smile in the end say's it all.

System test

After all sensors was mounted and the throttlebody was done and tested, it was time for a live system test. For this the system was rigged with a temporary harness.
Not all components could be tested eg. the injectors.
But the harness and calibration of temps, pressure and TPS was done.
Nothing of all this would be possible without my awesome buddy Olaf.
Thanks again Olaf! He is one of the very few that have backed me through this project.
Most others have been quite negative about the whole project so having guys like Olaf have been crucial to keep the spirit through the process.

Olaf in full action with the computer. 
(Same computer that decided to crash the same day the fist engine start was up)

First test of the system with Tuner Studio.

TPS vs Tecalemit Jackson throttle body

When brackets and all adaptation was done to the vintage Tecalemit Jackson throttle body I had to do some testing of the complete unit and it looked like this.
The vintage TJ throttlebody was now brought in to the new century !!



Shine

When the brackets for the throttle body was done I thought they deserved some shine and rust protection. Some Zinc plating gave the final touch.

Shiny brackets worthy a throttlebody
