FUEL INJECTED R65, Part:2

[Sosyal]

Hi all,

Finally, today I've finished all the fabrication, electric and electronic works, fuel lines, etc. and..... pushed the starter button. Yesss... it is alive   My 1983 fuel injected BMW R65 (aka UBER) is running.

Here's a link for who's interested, shooted with my poor cell phone camera at the VERY FIRST start:

Soon I'll shoot HD videos and share.

By the way, I took UBER to a short road test for performance, leaks and any loose parts and it passed.   Now, next step is the optimization of performance.

Cheers,

What a great accomplishment !!!!!

Any plans in the future to market this to the airhead BMW community ??

Thanks Bob,

I did not start this project to sell it but if requested why not?

I've tried to keep the bike as original as much. You can anytime change it back to carbs with only removing the injector bodies and arranging/attaching appropriate fuel lines.

I will gladly answer all questions and share my experience.

Here's another poor video, during a part of the road test:

well done!

Look forward to a parts kit been released, it'd be a welcomed improvement for the race bike!!

Congratulations.

Very impressive work, and she sounds good, as far as I can hear on the video.

What benefits over the old carbs do you expect to achieve with this set-up?

Or did you just do it for the sake of doing it?

Either way, 'kudos' to you.

@Mr.E.: I will list the parts used and share with the group.
@Steve: As you said, did it just to see if I can.

By the way, I would not convert the bike without the help of a friend who designed and programmed the control unit.

Tomorrow is holiday and time to take the bike for HD video shootings.

Cheers,
Ibrahim.

Today took my video recorder and tried to shoot the bike at action. Unfortunately my friend supposed to be the cameraman could not join me. So, I took this short video of the bike at idle.

thats brilliant, well done.
As said if you do create a kit of parts let me know!

Very cool!  Glad to see your (and your friend's) hard work paid off!

I imagine you could expect better warmup times and snappier throttle response?  Does the control unit handle choke (enrichener) duties as well when you start the bike cold like a modern car that idles high for a minute before letting the revs fall when the engine temperature starts rising?

Pair that with a digital advance unit and ICU from Motorrad Elektrik and I'd be willing to bet you could do away with all the usual carb/ignition problems!

[CaptainSlow]

Awesome job! That is seriously impressive  [smiley=clap.gif]

Luca,

Yes, the control software idles the bike high at (cold) start and decrease the rev. in accordance with the engine and intake air temperature. This first start was without the temperature controls but only the TPS connected. Therefore idle was high and mixture was lean. By the time being an OLED display to monitor the system is being prepared and hopefully we shall install it this week.

Cheers,
Ibrahim

OK, you've got me hooked, Ibrahim.

I hope you don't mind a few questions (probably the first in a long line of them).  

For the engine position sensor, I assume you've got a signal from an electronic ignition unit?  

For a load sensor, do you have anything other than the TPS?  (I assume that's the flat black box on the side of the intake?).  

Is there a temperature sensor on the intake unit?  

Did you have to attach an O2 sensor to the exhaust somewhere?  

Any other sensors?

Is the unit you linked to on e-bay the ECU?  Can you connect to it with a laptop and change settings?
