Circle jerk ? Not sure what that is exactly

Here, this will help...

Umm just looked that word up....

From the urban dictionary

1.) When a group of males sit in a circle, jerking each other off. 2.) *NOT* when a group of males stand in a circle to jerk off onto a cookie or a...

whats it do to mpg?

You crazy Americans. We just drank beer and told lies

whats it do to mpg?

Well, I got 34 mpg while riding all twisties at the WCR and I think I was riding pretty hard.

The mpg should also increase because EFI is now a fully controlled distribution of fuel not reliant on jetting and tapered needles.

Great Job Randy,

This is my next goal for my FJ. So to see it done on 2 separate bikes now is just awesome.

Is that a MicroSquirt under the battery?

Hi Randy,
would you happen to have a ballpark figure of the cost so I can save up until you have a release date.

Thanks,

I have no estimated time of release or even a cost point at this time. So far we are more than a year into this project at this point and until I am fully confident in all aspects of the system it will not be available for sale.

Mark,

I have no idea even what I have invested into the system as of right now. We have had to try several different fuel pumps, fuel filters, sensors and so I have spent much more than the system that is being tested right now.

Plus, each and every part was purchased at the retail level and if I am able to make this a production item, I will be seeking out vendors offering dealer pricing so I can build the kits.

I would love to give you a ball park, but I can't and wont until I get the system refined a little more to make sure we are able to use the system as it is.

As I have seen in the past, the time, effort and meticulousness you put into creating something new for all FJ owners is extremely appreciated and the products you put out are fantastic. I have already bought two oil filter adapters from you and I was very impressed by the quality. Still waiting eagerly for the handlebar risers to get here. I figured it couldn't hurt to ask and I was not insinuating that you would put less effort into this project as you have done in the past.

Thanks again,
Mark

No insinuation taken, I just can't put the cart in front of the horse on this one; I really do not know where I stand at this point.

I put it out there because people kept inquiring on the PM/email side and I just needed to be able to post about it once instead of a bunch of emails and PM's about the system.

I have too many times thought things were going to be a price or ready at a certain time and those plans have fallen through. The rear shock and exhaust system have both been the two biggest issues that have cost more time & money than expected.

I am still awaiting the exhaust system. I called three times this week for an update and a return call never happened, so I really don't know when to expect the exhaust. I was supposed to see them before the WCR and that past 4 weeks ago...

If and when I get more info that I am comfortable passing along I will gladly post it, but right now I cant offer anything.

Thanks for the interest and I hope I am able to make this a kit that will be available in the future.

On the subject of fuel economy -- any plans on making the system have different modes like are found on the newer systems ---economy mode -- cruising mode -- sport mode -- etc ---- I am thinking that is just part of the mapping but don't really know if it is necessary -----given the crew here they probably just want More Power mode.

Randy, fair dinkum mate, you're going to be responsible for my next divorce the way you're going. 

I'm looking forward to you getting this one sorted. I want my FJ1200 FI'd.  ...although it sounds like you're well down the track.

Best of luck, mate.

Steve, the Microsquirt V3 is pretty basic and does not support multiple, on the fly, user selectable maps (not in the Microsquirt documentation I have read....)

Of course you can build different maps in your laptop, but you need to connect it to the ECU to upload.

One feature that I've always liked in the aftermarket ECU's was a function called "auto tune"
Instead of tuning on a dyno, building all the tables, with auto tune you just input the fuel/air ratio target values you want for the engine's different rpm ranges, then go for a drive....the ECU learns (via the o2 sensor) what data you need and automatically loads this information in all the tables for you....
Need to make a change? Change the target values, go for a drive, the system makes the revisions based on your new target values.

That is a great way of setting up the system. FJ is fairly calm below 5,000 rpm, above that the engine wakes up. Sounds like the EFI can be set up the same. Could be the best of both worlds.

Pat/Randy,

I have my eye on building a MicroSquirt system. I will keep you posted on the results as I get it together. I plan to add a wideband sensor into the ecu. Then the bike could truly run on closed-loop and it would perform even better. I know of a few part that come with the ASIC chip already and are 0-5v plug and play units.
