Speed Six Bosch coilpack information

[ScottyOkinawa]

Anyone know if the stock Bosch coil pack, Double Fire Coil 3x2, 0 221 503 002, has a built in ignition module, external, or is it built into the factory ECU?
I've been trying to find the answer, but I can't seem to nail it down.

Thanks for any and all replies,

Was poking around in the boot and on the left side found the "Ignition control module" so that answers that, its extrenally controlled. Thanks for reading.

Which Car and year ?

Ignition Module in the boot would be unreasonable, there's no external ignition module with the MBE ECU in the Tamora/T350/Sagaris. Either the drivers are built into the ECU or the Coilpack.

Hi Evo, sorry, the car is a 2003 Cerbera.

The module says:
TVR Ignition Control Unit, Part No. ME0159

I asked the question as I am looking into an aftermarket ECU and the shop asked the internal/external/ECU question.
Looks like I'll need to change the entire ignition system for some aftermarket items.

Thanks for the read and reply,

The coil pack is directly driven from the ECU, what is the reason to change the ECU ?
If you change the ECU you most likely will need a new loom too.

Hi, thanks for your replies.
Hmm, if the ECU drives the coilpack directly, then what is the function of the "Ignition Control Module" sitting on the left side of the gas tank? Maybe because as someone earlier posted the Cerbera has the module and some other speed sixers are controlled directly? Do they all share the same coil pack or are the ECU's different I wonder?

The reason to change the ECU? I'd like full control over everything. From reading as much as I can about the SP6 engine, there are some issue to deal with and some I'd like. I want to add in a pre oiler circuit, the ole knock sensor, traction control, multiple fuel maps, better idle control and tweak out some of the flat spots in the accel curve on a rolling chassis, control over the cooling fans set points, speed controlled switch output control and rpm controlled switch output control to name a few.

Also, if the engine dies, I might just see about fitting a 2J, SR20 or other Japanese engine into her for the reliability factor and keep that beautiful chassis/body for the sex appeal.

Well, that’s the theory anyways,

The ignition module just takes commands from the black and red buttons on the steering column to start / stop the engine, it has no relationship with the ignition coil. As said above the ecu is direct fire to the coil with no separate ignition amplifiers, they are in the ecu. Any ecu that can direct fire ignition coils will work.

Awesome, thanks for the information!
Very helpful for the cause.
