I'm working on a small motorcycle fuel injection project. It has a bank of four small Mikuni carbs that I've turned into throttle bodies. I'm going to build a SyncroMAP circuit for these throttle bodies. The SyncroMAP circuit has a dedicated MAP sensor for each cylinder and it uses diodes to deliver ...

Dave, OK you lost me already. I am sure its me! More simplified question: I thought i connected pinout6 (fidle) on the relay board to the ground of the fan relay. When the ECU calls for the conditions to be met, it simply grounds the fan relay through the MS2? I am not using the fidle relay on the ...

I'm about to modify a 6-0 trigger wheel by removing one of the teeth to make it a 6-1 trigger wheel.

Here's a picture of what the trigger wheel looks like:

I'm going to remove the "long tooth" because it will keep the ...

Yuk - what a mess ... I think Matt's circuit and code would still work, although it would obviously have to be modified for 6 teeth. One point to be confirmed with the Extra devs, now that I think of it - CAN the Extra code do a 4 cyl with 6 teeth ...

Once again, thanks for the input Don, that is ...

Hey Don,

Would you believe that there's a wheel out there that's even stranger than the "3 short 1 long" wheel? Well how about this little starfish right here? Yep, this "5 short 1 long" is the stock wheel out of a Suzuki GSF400. This is why I'm asking about the 4 inch 36-1 wheel.

Hello Ignition Control Experts,

I'm beginning my second motorcycle fuel injection project. The first project was a fuel-only conversion of a Kawasaki EX250 (250cc parallel twin engine). Now I've got a Suzuki GSF400 Bandit (400cc inline four cylinder engine) and this time I want to do both fuel ...

It's been a while since I set up my LC-1, but I think I remember having to use the Innovate configuration software to set at least one of the outputs (probably the anolog output) to 0 to 5 volts. If I remember correctly the software presents you with a page that shows your current voltage range ...

By the way, that's a very eloquent description of which bikes typically use CDI and which use TCI ...

I just wander along, adding bits of other people's info to my backpack of info. That bit was a "keeper" so you have been assimilated.

I guess that in addition to crediting Matt_GSXR on that post ...

for one can I use the stock CDI tach signal(timing) to time the injectors?

Are you sure the bike has a CDI type ignition? I ask because Kawasaki road bikes tend to have Inductance type ignitions (also called TCI) produced by Denso Corp of Japan. TCI, especially wasted spark applications of TCI ...

Where are the MS and the LC-1 grounded? This sounds like a ground offset issue.

Okay Matt, now I'm interested...

If the MS and the LC-1 are grounded to different places and because of this are "seeing" slightly different A/F ratios, which of the two is likely to be more accurate?

I ask because ...

You're using MS1 which means you're fuel-only, right?

If you are trying to sense the Tach event off of the coil then I may have a fix for you. I also had reset problems in my fuel-only setup.

Look at the picture I posted in this thread. It works great for a fuel-only setup that senses the Tach off ...

Completely off the subject but the first things my eyes always go to on a set of Keihin carbs are the "phillips head" screws, because they're not phillips head screws. They're JIS screws.

Just look at that poor tortured-looking screw head in your uploaded picture. Partially "cammed-out" and looking ...

I believe you can only learn from other people's perspectives on a given problem, so here's a link to something that's been going on in the Kawasaki EX-250 (baby ninja) community. http://www.ninjette.org/forums/showthread.php?t=74579

A guy named Matt running a company called Ecotrons has developed ...

You're talking about this guy's work, right?

Looks like a very good solution to the problem; well engineered, proven on the road, etc., but it doesn't preserve the bike's vacuum-controlled slides which I really don't think the CBR250R ...

You may have more on your hands than you can handle with that CBR250R.

One of the signs pointing in that direction is the carb/throttlebody bore size issue. If you look around at the difference between "sport" and "super sport" bikes you'll notice the extreme differences in the ratio between bore ...

I think you're going to discover there aren't many people here on the Mega/Microsquirt sites that have any familiarity or experience with your CBR250 or the other small displacement bikes you mentioned. They're just not the usual targets for a fuel injection modification. I found this out myself ...

All I can say is wow, a CBR250RR. Honda didn't build many of them and there certainly aren't many left on the road any more. Your bike is a rare and amazing piece of Honda engineering.

I'm a fellow "small bike" guy, I've got a Kawasaki EX-250 running "fuel only" with a Microsquirt. I'm jealous of ...

I've finally got my Kawasaki EX-250 Microsquirt fuel-only project bike running. Now that I'm out on the roads TunerStudio and it's VE Analyze Live feature is kicking butt.

You're not the first person to ask this question.....

It's funny that the moment somebody pulls the carburetors off an engine and starts working on fuel injection they forget that up till the carb removal it was running pretty well on a steady stream of not-very-well-atomized fuel delivered by ...

Dito on the challenge to fit items on a bike :? I have moved everything you mention (plus a few more) on my "phase 2" session last year, and now will engage with another round with "phase 3" in what I hope is the final arrangement.
My bike may be larger than yours (R100RT BMW which is 1 liter ...
