Description

This is our race winning, widely used Jaguar AJV8 Loom & ECU Setup.

 

This setup will truely allow starting and running the AJV8 literally in anything. A car, a boat, anything.

 

We started running the V8’s on the MaxxECU Race back in 2018 with our partners Swallows Racing. We’ve developed pretty much every different type of AJV8 possible, Supercharged or Normally aspirated. This specific kit, will fit the 4.2, or the 4.4. It does not cover the 4.0, due to the different ignition coils. This fits the later type. We will have a 4.0 option available Q2 2025.

All of the connectors are genuine connectors, and crimped using professional grade crimping tools. You can run this engine using the S-Type Diesel gearbox using the Swallows Racing flywheel and clutch setup. Or, indeed you can run the ZF8HP. The Jaguar ZF 8-Speed Automatic gearbox. We’ve worked tirelessly to make this as seamless as it can be. We currently have the adaptor flexplate in the webshop, this will bolt up to the AJV8, and allow you to mount the 8HP Torque converter. The 8HP required is the 8HP70 from a 3.0D Jaguar XF circa 2015. These are widely available at a reasonable cost. We recommend Auto Reserve.

 

This loom comes with instructions on the cable routings around the engine. We have made the decision to not use the OEM throttle body. These can be troublesome even on the OEM cars. The Jaguar throttle body is expensive, and becoming more and more of a pain to get hold of. We decided upon the Bosch series of throttle bodies. It’s wired to plug into the 68mm Bosch throttle body.

Between Swallows Racing, and ourselves, we truly believe we’re offering the best available option to get one of these engines running perfectly, using the OEM sensors. Running fully sequentially, and indeed fly by wire, with knock control. As it came from the factory. We’re aware you can get lesser systems to run these engines. Mostly by treating them as a 4-cylinder, and doubling up injectors and coils. This was the ‘thing to do’ 20 years ago. We like to think we’ve moved on a little since then!

 

There are connectors for spare inputs and outputs near both the ECU, and on the engine. The one near the ECU has CAN connections, connections for the internal throttle pedal (Your choice of pedal), and a pair of digital inputs. These can be used for paddle shifters, or launch control etc. There is a 12-Way DT connector on the engine, ready for extra sensors. Oil pressure, temperature and so on.

 

This loom is constructed from Thinwall Automotive cable. It’s covered with heatshrink. The junctions are ATUM adhesive heat shrink. We supply two new connectors for the Coolant Temperature sensor, and the Air Temperature Sensor. All connectors, are labelled on yellow professionally printed heatshrink. This is covered in adhesive clear heatshrink.

 

The engine can run with throttle bodies, or the standard intake manifold for normally aspirated, or the Supercharged version. We will be able to log in and get the vehicle running for you online. We are able to provide base maps for most types of engine. We’ve tuned most varieties of these engines from a completely stock 4.2, to a wild Supercharged 750bhp race car. We have pushed these engines to the limits. We are widely considered the most prolific AJV8 tuners.
