Hello

Is HKS twinpower real 6 channel unit ie. could it control 6 coils?

Or could it atleast control 3 dualpost coils and run 20B in no split?

thanks!

Yes. We are using the 6 channel on our 20b with 6 coils. The "rotary" one is a 3 channel, you just need the universal version.

 

great....do you happen to have wiring diagram for universal version?

And what IF i buy universal version and will want to run it on 13B first, then on 20B? Do i just use 3 channels and another 3 leave unused?

thanks!

All you have is a 1 red, 1 black, and 6 yellow. Red goes to the coil 12V+ wire, yellows go to negative side of each coil and black to chassis ground. I guess you could just run three channels and tape off the other three, same as the 4 cylinder engines just running 4 channels

 

Will this multi channel unit run the factory 20B coil packs...?

Thanks

 

There is no reason why it wouldn't work. The Cosmo has two coil packs, that are made up of three coils each, the connectors both have four wires (1 power, 3 triggers). Connect the HKS TP between the igniter and coil packs.

 

I have 6 channel HKS DLI here now, Z32 igniter and 6 individual coils (out of FC3S trailing coil packs)
Wiring it to Haltech PS2000

Ignition output from haltech is negative ?
Could someone confirm this wiring is correct??
Doesnt ignitor needs 12V+ too?

 

The igniter will need to be powered, but you need check the Nissan FSM to see how it is wired.

 

Unless its getting signal by 12V+, its not powered.
And by looking at this picture, i have it switched over in my diagram.

I should be Ignition and E should be ECU
G is for ground :

 

The PS series can output as rising edge or falling edge, you should check to see what the Z32 ignitor needs to see. If the ignitor is getting a common ground, I would think it would need to see a rising edge signal, but that's just a guess.

 

This writeup on E11 install to Z32 has set ign output to falling edge....and constant charge..

If running 3 relays for 6 coils, each pair of coils will have its own 12V+ wire.
Will it be ok to connect HKS red wire to just one of these power wires, or could it 12V somewhere else than at coil + ? Maybe it should have its own relay?

Thanks!

 

It is fine to connect it to one of the 12V+ at one of the coils. That is how HKS has it wired. Look at the FC install

Now, tricky question.......

How do i know its working?

I had Crane Hi6 on 13BT setup and i could have said that its working just by the look at the spark. And the way it was wired, if something failed, u would get no spark at all.

Now, with HKS Twinpower and way its wired, it will still produce spark whenever its working or not, connected or not. And by the look, i dont see difference when i disconnect it.

 

Let us know how this set up works out for you.. I been wanting to do this for my 20B.

 

Anyone?

 

I've contacted HKS and they said no piston twin power will work with rotaries.

This is what they wrote me.

 

^ that sounds like a useless corporate response. with a 3 rotor unit it is an "off label" application so they aren't going to give you any advice. The rotary ignition systems of that era are really not significantly different than the piston engine wasted spark systems with external ignitor boxes

i think for most people they have spark blowout first. then they install the HKS Twin Power and it goes away. so it's pretty obvious that it's doing its job in that case.

 

Well, there must be way to 'measure' even without having some problems at first

 

dyno it. you should see some sort of power increase when dyno'd back to back.

 

We are talking electric device, i would rather measure it directly (multimeter, osciloscope etc...) instead of measuring its affects on power output which is naturally affected by many other factors.... Not saying your suggestion is not valid, its just not 'proper' way.

If in doubt about tire pressure, i measure tire pressure and not the lap time....

 

I'm sure you would see it on an oscilloscope if you actually had an oscilloscope and knew what to look for. I've never seen a before-and-after waveform comparison though.

 

Any updates on this?

 

Nope, winter is here with lots of snow and up to -20C deg weather, not really motivating to work on car outside.....

 

Two coil packs with three coils each? Does this mean that the cosmo has no split ignition? Is this the for NA cosmo only? Does the 3 rotor turbo cosmo have the same ignition set up( no split)?
