I carefully cut the hose of the suzuki fitting and clamped on a regular piece of -6 fuel line. there s an oring in there be carefull not to cut that.

what FPR are you running with the returnless fuel system now?

750essess · « **Reply #403 on:** February 19, 2011, 12:11:49 PM »

the puel pump controller varies the speed of the pump by way of feedback from a pressure sensor. no regulator is now needed.

J.Webster Designs · « **Reply #404 on:** February 19, 2011, 08:22:50 PM »

your going to have to explain this more... or direct me to the information where i can learn more about thins fuel pump controller on the microsquirt... I haven't heard anything about this feature....

750essess · « **Reply #405 on:** February 20, 2011, 05:01:04 AM »

I mentioned it a few pages back. Its not a microsquirt feature. Its a seperate circuit I got from madhu.com, there is info on his web site and just email him if u want one.

J.Webster Designs · « **Reply #406 on:** February 21, 2011, 04:29:45 PM »

is it just PWM? or something different?

750essess · « **Reply #407 on:** February 22, 2011, 04:34:35 AM »

yes pwm with feedback from a pressure sensor on the fuel rail.

How is your bike performing now ? Anny updates?

Does it work well whitout the regulator?

lucky · « **Reply #409 on:** August 20, 2011, 02:56:46 PM »

Too bad there are no photos.

I went to that orleans.com site and it was just about bicycles.
No links to the fuel injection project.

Like I said, no easy way to mount the sprag to light metal rotating element..
You are the first one to post up why it is kick only, everyone else just quotes the website. So, not knowing, I called Ken. Then I read your post.
Interesting, as i understood it, you just wanted to know if it worked with electric start..?

Page #7 still no photos or links that work.
Still cannot see a photo of this fuel injection project.

This is a fairly old thread mate, probably the reason the links have died, i have all those bookmarked but mine have died as well. These guys pop in now and again so be patient.....

750essess · « **Reply #415 on:** August 21, 2011, 12:26:34 PM »

here s the current configuration:

microsquirt module with jbperf.com inj/ign driver bd ( only using ign part right now, will switch to full seq inj this winter)

msextra 3.1.1 firmware 12 tooth crank wheel one tooth missing.

ltr 450 fuel pump controlled by madhu.com fuel pump controller and aem fuel pressure sensor set at 40 psi

note : i had to run a vent line from pump to above gas level to solve random fuel starvation issue

750essess; Good to see our resident EFI guru still around. Is there any chance you could post a picture of your VE table for us? I know I am getting real close in my settings, but it would be nice to see another SOHC table just for comparasion. Also, out of pure curiosity, what have you got your required fuel set at?

Thanks for your inspiration...here is where I am at...still got a ways to go yet...but getting closer:
021.MOV
016.MOV

Take care; Clifford

Why do you have it idling so rich? Or is that cold start enrichment?

23tbucket · « **Reply #420 on:** August 22, 2011, 08:45:13 PM »

750essess; Cool map, but I was thinking more on the lines of a table where the RPM's are on the bottom and the MAP is along the side...like this:
http://i258.photobucket.com/albums/hh280/23tbucket_2007/045-1.jpg

Pinhead; Lots of tuning to do yet. I think my fueling is very close above idle and above...even when I'm in boost things seem to be running very well. My biggest problem with this supercharged bike has been the cold starts and idling parts. I've found the engine idles the smoothest on the rich side. If I lean the mixture, even just a bit, the engine "hunts" real bad and eventually stalls. Even my turbocharged DOHC idles so very smooth when rich..I can idle the DOHC engine right down to 500 rpm's if I want. I would like to bring my SOHC idle down lower, but as soon as I put the automatic in gear it quite often will stall, unless I bring the rpm's up to 1500 or so. I think once I get a better handle on how the supercharger is affecting the starts and idle things should get better? A natural aspirated engine would be so much simpler to program!
Also when you first start an injected engine (either cold or hot) you have a few things adding fuel; priming pulse, cranking pulse widths, afterstart enrichment, warm up enrichment...then things start to go off of the main VE table and Air/Fuel ratio table if you are using "closed loop" Some work separate from the main table..others use a portion of the main table.

Another problem I'm running into on both my turbocharged bike and this supercharged bike is how to correct the fueling equation as the intake air temperature increases......so much to learn yet.........!

I just inherited a small notebook type of laptop from one of my sons. It will fit nicely inside my jacket. My daughter has found a cable to link up this little laptop to the microsquirt. She was also able to download all my present files into this device. If I can ride my bike and collect and store data at the same time this would be the best ever!!! Better than burning up Dunlop's....lol

All of us that are fuel injecting these old Honda's are in new territory.....we need to learn as much as we can from each other. There is not much info "out there" other than this SOHC site for small 750cc air-cooled I-four motorcycle engines.

Who knows...maybe 5 or 10 years from now, you can buy plug and play fuel injection for whatever?

Pinhead · « **Reply #421 on:** August 22, 2011, 10:02:30 PM »

Sounds to me like you could use a bit of an ignition power boost... What coils and dwell are you using? IIRC, the Megasquirt/Microsquirt has adjustable dwell which would allow you to use modern low-resistance coils for a much more robust spark.

With my limited FI experience, I'm guessing that with a leaner idle mixture, manifold vacuum drops off which causes the MAP sensor to signal the ECU to pull timing, which slows the engine, which reduces vacuum, which pulls timing... You know where I'm going.

Stronger ignition can often-times correct (or at least reduce) this issue...

23tbucket · « **Reply #422 on:** August 23, 2011, 07:40:56 AM »

Pinhead; I have the Power/Arc optical ignition with the four built-in timing curves. I should have gotten the programmable one or use the microsquirt system like 750essess has done. If I could keep the timing fixed up to 1500 rpm, I think this would solve most of my low end idling problems.

You are so correct.....timing changes just a little....map pressure changes...rpm's change...different fuel amount injected....timing changes again.....map changes again....on...and ...on....... With the positive displacement supercharger on this engine just a few thousands of an inch movement on the throttle butterfly and lots of extra air gets pushed into the cylinders instantly. At idle the supercharger is churning a lot of the same air inside... this heats up the air..making it less dense...then when you come off of idle and engine is using more air...the air cools down and becomes more dense....all the time the ECM is correcting things to what the dummy has programmed into it!!!!

Electronic fuel injection is crazy stuff indeed....but soooo rewarding: ..... the day you first get the engine started and running by itself....then the day when you put some road under the bike......I've got 240 miles on my bike so far......just another 10,000 miles and the tuning should be good to go!!!lol

750essess · « **Reply #423 on:** August 23, 2011, 10:47:39 AM »

mine likes to idle on the fat side too, around 12.5 to 1. Im hoping sequential injection will help this. Have you checked to see if the o2 sensor is accurate? If lc-1 hook a seperate computer up to the digital output and see if matches what tuner studio says. If you are running the extra firmware there is a table to adjust the air temp correction. You get it tuned well at say 72 deg then adjust the curve if the afr changes with intake temp. The ecu uses a formula to calculate the air temp correction but in some situations you need to modify it to account for heat soak of the sensor or manifold quirks

Syscrush · « **Reply #424 on:** August 23, 2011, 11:19:51 AM »

Is a 12.5:1 idle a problem? Will the plugs foul at that mixture?
