USB-serial adaptors

USB-serial adaptor for computers lacking a serial port.

Many new laptops and PCs do not come with a serial port.  These adaptors plug into a USB socket and allow you to connect up to your ECU. 

Many cheaper adaptors give problems, these adaptors use a premium chipset and tested to work with Megajolt, Megasquirt and Emerald ECUs.

Hard cut rev limiter

Hard cut rev limiter board for Megajolt systems
The Megajolt ECU includes an ignition retard rev limiter as standard.  The hard cut module works with the existing soft rev-limit and fits inside the ECU case.  When installed the soft-limit of the ECU automatically retards ignition timing to zero degrees 100 RPM before the hard limit activation point. This makes for a progressive application as you reach the rev limit.

Tacho Driver

Tacho
tachodriver130
Tacho driver module for coil-driven rev counters
Suitable for Megasquirt, Megajolt and many other ECUs the tacho driver allows you to retain your existing coil driven rev counter.  If you have a more modern rev counter accepts the 5 volt output of most ECUs then you do not need one of these.

Please note that some rev counters can be particularly difficult and may require additional tweaks to work correctly.

Distributor blanking plug

If you've converted to a distributor-less ignition system you probably don't want your old dizzy left on your engine.

These blanking plugs allow you to remove the dizzy and plug the hole in the block they leave behind. Designed for the A-series and A+ series engines these aluminium distributor blanking plugs come complete with O-ring ensuring a tight seal. 

With 27mm and 34.8mm diameters these plugs can be used to plug the distributor holes of a number of other engines.  The Ford Crossflow in particular can use the 27mm (A+) blanking plug

Unsure of which type you need for your engine?  If you look at the fixing for the distributor and the distributor is held in with a separate bracket, secured by a 3/8" UNF bolt, then you need the A+ bung, however if it has a 1/4" diameter bolt through a hole (at about 2 o'clock - the distributor being the centre of the clock) then you need an A series blanking plug.

It is essential that once the distributor is taken out that the distributor drive shaft and sleeve (A series only) is also removed as failure to do so may result in damage to your engine.
