    NZEFI Idle Speed Control Solenoid Conversion

    If you are running aftermarket engine management (or plan to) this is a must. Using the factory stepper motor consumes 4x output channels, where this unit only requires 1x, leaving you free to assign outputs to other functions. The stepper motor itself is simply a Ford Idle Motor, but it's the...

    8HP Journey

    I've reached a crossroad with my car where I'm considering building a forged engine and swapping out the little single turbo for a pair of decent twins. The A340 would not handle this very well - as it's already starting to slip under heavy throttle and boost. Rebuilding an A340 to handle...

    In-Car Valve Body Replacement

    Having swapped valve bodies a few times now with the transmission still in the car, I thought it might be useful to share some hints. Thanks to gravity and kinetic energy, as soon as the valve body is removed from the transmission housing, 3 out of the 4 accumulator pistons will normally fall...

    Lexus Diagnostic Signals Chart 1UZ-FE

    Cleaning out the garage and stumbled across this gem - an A1 size (594mm x 841mm) 1991 Lexus Technical Training poster for 1UZ diagnostics. The poster shows pinouts, internal circuitry, DTCs, oscilloscope patterns, It's printed on a huge plastic sheet, designed for use on top of an overhead...

    Catch Can Theory

    In prep to build a catch can setup, I've been weighing up the pros and cons of commercially available units and most of them are crap. Either the flow well and catch nothing, or they catch lots and restrict the air. One thing that stands out is that gas flow against a surface that opposes...

    Coolant Temp Sensor Calibration

    Something I've found recently that should be shared... When setting up aftermarket ECU, there are often pre-configured tables you can use to align your coolant temp sensor reading with the actual temperature - effectively teaching the ECU how to read the sensor. In the case of a Haltech, you...

    A340 Valve Body Upgrade

    Through the process of building turbo 1UZ E36 BMW, I'm changing the valve body so it can handle boost more effectively. PROBLEM - the Soarer 1UZ A340E valve body uses: cable from the throttle body to control line pressure (the more right foot you give it, the more pressure you get) solenoid to...
