FUEL INJECTED R65, Part:2

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  Cheesy 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.  Smiley Now, next step is the optimization of performance.

Cheers,
Ibrahim

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:

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.

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!

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?

Hi Evan,
I could not log on to the site and update the progress for a long while and I will be happy to explain/answer as much as my English let me. So, do not hesitate to ask whatever you want.

For the engine position sensor, I've got the pulse from the Ignition Control Unit. I've used an insulated cable (ground wire is coaxial over the live wire) in order to eliminate interference.

Only load on the engine is measured with the TPS. You're right, the black block on the left injector body, which the body belongs to an R11xx BMW.

There's an air temperature sensor attached between the two nozzles at the top cover of air filter.

Engine temperature sensor is located under the air filter. I've dismantled one of the air box screw that keep the box attached to the body and inserted a small sensor with the same thread.

I've a "portable" O2 sensor which can be attached to the exhaust exit of the muffler. This sensor reads the fuel/air ratio on the exhaust and corrects the mixture amount via the custom made control unit.

The unit linked at e-bay is only a processor. We've designed and have it produced a control unit which has the said processor installed. Later on found some errors on the PCB and corrected the faults. I need to re-design the PCB and have it manufactured again. Primary design of the PCB is here : http://www.flickr.com/photos/94158592@N03/8570979497/in/set-72157633036229410

My friend, who is an electronic engineer wrote the whole program. All the settings can be modified with a laptop. Even we put 3 tiny switches on the PCB which can be programmed and used to change the settings. For example, increase/decrease fuel level at various RPMs.

I hope I could answer your questions.

Cheers,
Ibrahim

If the need or desire ever arises to move that "portable" O2 sensor, I bet you could attach it to the rear exhaust crossover pipe.  The pipe might be a bit narrow to simply stick an O2 sensor bung on it, but you could probably fabricate and weld a small box or pipe T onto the crossover and attach the sensor to that.

Thanks very much for the info, Ibrahim.  I've been fiddling around with much of this stuff on my Miata (I installed a Megasquirt kit), so I find it exceedingly interesting.  I see that there is a Silent Hektik kit available for the R65, but it's about $3,500.  If I recall, they use an engine temperature sensor hooked up to the cylinder fins.

After a long interval hello again,

I've 2 new videos for who are interested at the project:

http://www.flickr.com/photos/94158592@N03/11943498744/in/set-72157639755385315

http://www.flickr.com/photos/94158592@N03/11943326355/in/set-72157639755385315/

Till from my last post here, I've performed the following:

1) Road tests and optimized the fuel/air ratio on the software
2) Checked and corrected crank position and corrected fuel injection sequence as per the intake valve opening and closing degrees
3) Corrected a fuel flow error at 5.000 rev/min
4) Finalized the fuel line route and changed the fuel hoses with higher quality pressure and heat resistant ones
5) Changed the rear tire
6) Installed reynolds trunk rack and a 22 liter top box
7) Installed an LCD display to monitor fuel flow, engine and air temp., battery voltage, throttle position and rev./min
8) Connected a gas analyzer and checked the exhaust

Remaining works are:
1) Install the O2 sensor and make corrections to the software if necessary
2) Check and adjust the valves if necessary,
3) Cosmetic touch up, such as the pinstripe on the tank and tank emblems
4) Paint the valve and starter covers

It's running smoothly and ready for the Spring Smiley

Cheers,
Ibrahim

For those who are interested with my project,

Bike is running perfect (well, frankly speaking I can still make some adjustments but currently it revs up easily) and almost all cosmetics are done except the tank emblems.

Is it possible to post videos here or should I give a flickr link where I will upload them?

To sum up, I've installed a display to monitor throttle position, engine and air temp, battery voltage, rev and fuel ignition amount in miliseconds. Also adopted a throttle/choke cable box from an R1150 for cold start which is operated by the original choke lever.

It seems everything is OK for long a distance ride.

Cheers,
Ibrahim

Sounds great Ibraihim !!!!!!

I don't think you can post videos here .
I think Rob Valdez can provide an answer to this question .
But you can provide a link to some site, like youtube for members to view a video, I've seen that before .

You're one step ahead of Silent Hektic, since they don't have the o2 sensor.  Actually, two steps ahead, since they supposedly don't make them anymore. 

If you have some entrepreneurial spirit, please consider selling kits.

Hi all, update for the fuel injected R65 are the cosmetics. Still missing the emblems and the wrong color at the side panels but it's there: idling, running and all OK.

Cheers,
Ibrahim

Hi all,

For those who are interested with my project, my fuel injected R65 (AKA "uber") successfully completed its first long distance ride. Total distance from home to camp area is 400+ km. Fuel consumption was 6.7 litres per 100 km with an average riding at 4.5-5 thousand rpm.

I will upload photos to my flickr album and provide the link.

Cheers
Ibrahim
