Lotus Twin Cam Electronic Ignition

Suitable for: Lotus Twin Cam

Our typical electronic ignition package includes a modern ‘wasted spark’ twin coil for distributorless ignition, which is controlled by an ECU that responds to both engine speed and load. Engine speed is measured using a specially produced toothed front pulley and engine load is measured with a throttle position sensor mounted on the carb throttle spindle.

As well as being neater this system can deliver considerably more spark energy than a traditional ignition coil. This is especially beneficial for race engines with a higher compression ratio. Of course a twin coil unit also does away with potential points of mechanical failure (e.g. damp in the distributor cap).

A typical package includes:

• DTAfast Ignition management ECU* (and engine bay wiring loom)
• Toothed front pulley
• Crank speed sensor (and mounting bracket)
• Throttle position sensor (with DCOE mounting kit)
• Twin coil ignition pack (with distributor blanking kit)

*ECU will come loaded with a base map which matches your setup as closely as possible. However, this, as with all generic maps, will still need fine tuning on a dyno.
