Optimax ECU Chip Remap for 3.9 Hotwire - Land Rover Discovery, Range Rover Classic, MG, Morgan etc

£375.00

Product information

Here we have the essential Optimax ECU chip for the Hotwire fuel injection system used on the Rover V8 engine. This is an essential upgrade for all standard 3.9l Hotwire powered vehicles. Don't however make the mistake of thinking that this is a horsepower chip like so many others; this is a correction chip aimed at righting the wrongs of the standard Rover fuel map and therefor improving the drivability, smoothness, efficiency and reliability of your engine. In most cases this is a plug-and-play part using some basic tools and knowledge, with full fitting instructions provided. Alternatively a fitting service is available, please enquire for more details.

The chip here makes a huge difference in driving to a wide range of vehicles whether they're Range Rover Classics, MG RV8's, Morgans, TVRs, Discovery 1 or any other Rover V8 powered vehicle with the Hotwire injection system. As standard, these vehicles all ran the same Range Rover fuel map (with the exception of TVR who dumped excess fuel in at the top end to try and boost horsepower), which is completely incorrect for vehicles which aren't 2.5 tons and four wheel drive. What's more is that on the Range Rover, the fuel map runs lean on cruise which can cause its own issues. All this means there are vast improvements to be made regardless of the vehicle too, even on a standard engine.
