Competition & Performance vehicle Wiring & Electronics Services

Ecu & dash/data logger installation, Configuration and tuning .

From stand alone ecu looms & installations through to full competition vehicle looms incorporating engine/powertrain management, data acquisition systems/dash loggers, expansion units, CAN bus networks, electric waterpump speed control via ecu and ancillary electrics such as rain lights, wipers and charging systems.

Raychem DR25 is used for the loom coverings along with M22759/32 millspec wire to provide a quality loom that is durable & resistant to oil, fuel, heat & the arduous conditions found in the engine bay and is significantly lighter & more compact. Our experience means best practice is used for sound construction and electrical noise suppression along with quality materials. A quality loom may appear expensive at first, but an amateur job with little understanding can result in far bigger costs due to damaged components and hours of fault finding.

You can bring the vehicle to our facilities for the installation or we can travel to your location if required.

To complete the project we offer dyno tuning services with access to Dynapack hub dynos in both the South and North islands.

We also offer on the track development of traction control, launch control, boost control, flat shift & gearbox control systems.

Diagnostics & Engine management fault finding

For both aftermarket & factory engine management. When these go wrong many garages simply throw new parts at the car on gut instinct until the problem goes away (the problem may not actually be fixed but masked temporally). P1 Motorsport has the equipment & the full understanding of engine management to be able to fault find in a logical process, testing sensors & actuators & the mechanical condition of the engine itself.




Data Acquisition Services



Over the past decade data acquisition systems that were previously only accessible by the pinnacle of professional motorsport have come more & more into reach of the amateur racer. Weekend racers are beginning to cotton on to the benefits of capturing information about the car can offer in terms of looking after the health of the drive train & improving both the car and drivers performance.


Many are put of by the perceived complexity of the subject – this is where we can offer assistance. We can assist you to select a system that suits your needs, application and how deep you wish to go into the data logging world. We can then install and configure the system to give the best reliable results – our experience means we can configure the software to maximise the systems potential (rather than install the system, setup some basic functions & send the car out the door). If required we can also offer assistance & training on how to configure the system to suit your own day to day needs, down load the data, manage the data and interpret the data. Free technical support & tuition is provided for each data logging system we sell.

Example tow-in/drive-out road car project; Riley brought his Series-7 standard road car to us on a trailer with the stock twin turbo engine in pieces. We fully rebuilt the engine as a bridgeport turbo, supplied & fitted the T04Z turbo, exhaust manifold, Tial 60mm gate & exhaust, custom fitted the V-mount intercooler/alloy radiator, comprehensively upgraded the fuel system with new braided fuel lines/injectors/fuel rails/regulator, removed the redundant engine wiring & tidied up the tired looking loom & then installed & tuned an aftermarket ecu.
