Here's are few photos of a system I have been wiring for a customer. It was a common system on 1uz power stock cars over here in NZ a few years back but many have now moved to full standalone ECU's which give a fully adjustable timing map (like the Link Lightning) .
It was sold by a supplier of Procomp equipment over here to a stock car supplier who added the coil and modified drank trigger wheel. Then sent to Oz to the customer who sent it back to NZ for wiring so it's been well traveled.
As it's a older system I will include some part numbers.
The control box is a Procomp PDH4-M. MSD make a similar product.
The trigger wheel has has a new key slot cut at about 35/36 degrees offset to standard. Stock trigger has around 4 degrees of offset so this new slot is heading towards a timing of around 32 degrees BTDC.
The coil is a Diamond FTM-630A1. This is a double ended coil unit from some mitsubishi vehicles.
With it all wired up and tested it does work quite well. As it's for stock cars it doesn't have any change in advance. One point of interest I have is only one rotor points towards a firing cylinder at anyone time and the other side of the coil goes into a air gap between two coil towers. I think the only reason this works is the unit is a CD ignition unit so the coil is able to fire fine with only one side working. In a normal situation it would require a full circuit of both sides complete.
Now back to Oz it goes.
