RV8 Remote Ignition Module Kit STC 1856 Installation Remote Ignition Module Kit the Module is not visible in the photo as it is mounted under the bracket below the plug shown on left side of bracket Photo Simon Austin Simon Austin offers this modification saying you re not likely to find any reference to the remote ignition module kit in any RV8 manuals as the kit is actually intended for use on Land Rover vehicles Since the RV8 uses the same ignition system as the mid 90s Land Rovers this remote kit can be added to an RV8 The main reason for the kit is to extend the life of the ignition module by getting it away from heat Since the original module is attached to the distributor heat transference through the metal is a concern As we all know heat is an electronic component s worst enemy Why install this kit The RV8 ignition system utilizes the same components used on Land Rover vehicles of that time period Incorporated into this system is an external Ignition Amplifier Module mounted directly to the distributor This module is wired into the ignition circuit between the coil and the distributor As we all know heat is an electronic component s enemy In order to prolong the life of the module a kit is available to remotely mount the module away from the distributor usually onto the nearside inner wing The installation of this kit is not a requirement for an RV8 The stock system was designed by engineers who I h

7. ope can be trusted Your car should provide years of enjoyment without this kit With that in mind and after chatting with my local V8 Register MG Car Club 120813 RV8 remote ignition module Land Rover specialist decided that anything could do to extend the module s life by placing it away from heat seemed like a good idea For what it s worth the module that came off my car was the original with a build date of 04 94 so it certainly didn t owe me anything For an electronic component to go this long was impressive Unfortunately the original module also contributed to rough idle issues with my car so it was time for it to go Does it work Only time will tell One would have to have two cars one original and another with the remote kit in identical condition and driven in the same way for a number of years to see how long their respective ignition modules might last However during my tuning issues with my RV8 NNN 0590 after importing the car from Japan replaced the original module manufactured in June 1994 and that made the biggest difference to the rough idle issue the car had at that time So the modules will last a long time hopefully My local Land Rover specialist in Canada helped me sort out the issues and while talking to the owner about these kits he said Land Rover actually moved the module on later vehicles He agreed that anything that could be done to extend the module s life was a good idea getting the modu

9. prolong the life of an electronic component was worth it Land Rover themselves moved the module on later vehicles so that must mean something The other benefit to this kit is it uses a Rover ignition module not an aftermarket unit had a brand new aftermarket unit fail after less than 400 miles did install a Lucas module after this failure and although it s worked well enough over the miles the Rover module just seems to start the car a bit better I ll keep the Lucas as a spare The kit purchased came from JSF 4x4 in the UK Angus Munro was kind enough to accept delivery of the package and forward it to me in Canada did find out later can get the same kit from my local supplier but at higher cost My thanks go out to John Cumming for his technical advice and to Angus Munro for being a great parts distributor
10. unning Light module required by Canadian Law to be installed on our vehicles The pink wire shown in the two preceding photos is connected to this module Since had to find a new location to mount the kit had to drill out holes in the inner fender and then remove the paint around the holes to provide a good ground It can be a bit unnerving to drill holes on one s car but once the first hole is drilled you re committed and the nervousness goes away hope John doesn t mind again but here s a photo of his kit mounting location Similar to mine but a lot straighter The actual wire connections are as follows Coil original white and white black wires from stock harness White wire labelled 1 in photos from kit to terminal White Black wire from kit to terminal Kit long harness 18 Shown in Photo 1 connects dummy module mounted on distributor to the black oval plug shown in John s photo just above with blue and red wires showing The stock rectangular plug that was connected to the original distributor mounted module is no longer required but not to be removed Itis best tied off so as to prevent getting caught in any moving parts This is a photo from John showing this V8 Register MG Car Club hope the information and photos are clear enough and provide enough insight into installing this kit Is the kit worth the cost and time to install As mentioned in the beginning felt that anything could do to
