We're really excited to offer EFI kits for the TVR Rover V8 based cars.  Whether you have a 3.5, 3.9, 4.0, 4.3  or 5 litre you need to upgrade to this kit.   
Not only are you going to get more power with this kit, but finally some good economy too (within lead foot reason of course).  
​
Our kit comes with a range of ECU options, but the base option is a  microsquirt ECU.  Your car will run on a trigger wheel that disposes of the old distributor system.      Form there you no longer run a MAF system, but convert to MAP known as speed density.   Your ECU will come with a base tune to get you going, and will be very close to perfect.  From there you can auto tune the rest yourself, or hand it to us to install and tune in house.
 
* Wideband - this is an AEM wideband.  The kit performs best with a wideband attached.  A wideband gives constant information to the ECU and adjusts the tune under all conditions.  This is also the only way to accurately tune the car once installed.
 
* IAC - Idle air control.   The idle air control is not necessary, but is a creature comfort that all modern vehicles have.  It brings the idle up when the car is cold and settles it down as it warms up,   When you crank the car to start it will give it more air like you are starting with mild throttle.
The TVR does have this, but is old technology using stepper motors, and this kit will not control it.
 
* Injectors.  This is a must have upgrade.  These injectors are far more advanced than the standard injectors.  They are genuine Bosch and have a 4 nozzle spray pattern compared to the OEM 1 nozzle.   Generally by now the injectors in your car will have dirt and uneven spray patterns.  This is a great value fix and upgrade for economy and power.
