How would you go about a crank trigger on a Suzuki TL1000 (which is a v-twin) for the ignition signal on the 882?

Or are there other methods for getting a ignition signal to the 882 besides a crank trigger?


Thanks

There should be some sort of target already on the crank/cam.

Find out what it is and I'll tell you what can be done.

24-1 seems rather common for motorcycles, I wouldnt be surprised if there is that target already in the bikes motor.

Only thing I found so far, appears to be a 4 tooth sensor on the flywheel, 3 "short" teeth and then 1 "long" tooth.

4 teeth on the crank is very poor resolution.

Years ago, after spending an afternoon on a spreadsheet, calculating what the potential timing errors are for various crank tooth counts, I decided not to support crank tooth counts less than 12 since the intertooth timing error was deemed unacceptable to my performance goals.

The ECU882-C supports many targets ,but the lowest count target is 12-1.

That said, if you want to use the 882 on this engine, you must find a way to get at a supported target onto the crank.
12-1, 24-1, 36-1, 36-2, 48-1, 60-2 are common crank targets we support.

There are also some "cam" side targets we can talk about too, but they start at 48 teeth.

The Crankshaft Target could be removed AND "teeth added".

The resolution would have a GREAT increase, your engine will "rev" 1000-11,000 in one second.
Thus, the need for reduction of Timing Lag is great.

Can the CT be removed from your crankshaft ?

There could be two common choices of "pattern".
The "T-Rex" pattern of 24-2 OR Honda (upgraded) of 12-2.

I would be willing to help with the Solid Works "redesign".

Aren't the Hayabusas 12 tooth or 24 tooth depending on the year?

Maybe since it's "in the family" trigger wheels may be swappable??

I will look into the Hayabusa, I have very limited experience with Motorcycle platforms. Thanks for the advice

I found out that I actually have the TL1000R Engine, but I can use the Flywheel off of the SV1000 which does have 24 teeth.

So with that being said, the 24 tooth wheel will trigger the 882 with no problems?

And for true sequential injector firing, I could use the cam sensor that's built in?

Thanks

Does it have a missing tooth from the 24 (meaning 23 teeth and a missing tooth section?

For true sequential injection and ignition, you will also need a single tooth on the camshaft with a HALL output.

If you need sequential, but not "true" sequential you can run the injectors in a random phasing, and ignition on waste spark.

Hi, we have THREE wheel codes for 24 tooth Target Wheels.

1. Code "24" is for a TW with ONE "missing tooth".
2. Code "22" is for a TW with TWO "missing teeth".
3. Code "25" is for a TW with NO "missing teeth".

Code 25 uses the Cam Sensor to "find home" at "0"

The other Codes can use a CAS input (Hall) to fine "phase"

We support this 24-2 wheel code. (T-Rex)

KHI uses this TW on their V-Twin "T-Rex" ATV.

We have "won our class" in the BAJA 1000 mile race for two years.

You will need to STATE your current Firm Ware level as this is a newer wheel code for the year 2008+.

Your system will work perfect.
