Coil Packs

trevor1986 · Post by **trevor1986** » Wed Mar 28, 2012 4:08 pm

I'm just wondering if there is a way to use some type of coil pack and control it through nistune on a ka-t type 3 board. I'm not aware of a way but I want to make sure.

Thanks

Only things you can control is dwell time and dwell duty inside Nistune in regards to coils

Would that be all i need to make them work?

You'll need some extra hardware to sequence the coils too if a dizzy is being used ATM.

Or are you wanting to replace the large coil with a single small coil pack coil ? You may run into spark issues at high RPM [low energy] with a coil pack coil [saturation and charge problems]. They were designed to run in multiples (4 or 6), so you'll effectivly be running them at 4/6 times the design RPM !!

I have some compact, serious output coils available if needed. [40+psi and methanol is not an issue]

I was just looking to do the LS2 coil packs with heatsink. I know you can use them on the ka but I've only seen it done on standalone, but what I read all you need to do is adjust dwell time and dwell duty cycle, I just want to know if they will work with nistune. Any insight on that question?

This is what I'm wanting to do.

Anymore input on this?

Well I believe I found my answer, correct me if I'm wrong but ill need an ecu that will allow for 4 ignition coil signals.

KA24DE ECUs have 4 coil outputs

Would you by chance know the pin numbers for those Matt? I looked and couldn't see them.

sound be same as SR20DET

8 Igniter Drive No 3
1 Igniter Drive No 1
9 Igniter Drive No 4
2 Igniter Drive No 2 (tacho on DE = Y/R)
13/6 Ign signal GND

I'll check, thanks Matt.

Well after search a lot this is what I found if you look in the link there is a pinout for a 95 obd1 ecu and I don't think sr and ka have the same options.

Type 3 board is 1991-1994 ecu. Coil 1-4 on second column of that diagram. Only distributor models have single coil

Yeah I have a type 4 board with dizzy.

Okay well you are correct since you only had the single coil. First post was misleading
