how does cruise control get it's speed reference signal and does it then hand shake back to the ecu afterwards. Al

Does anyone know if you can get the stepper motor for the idle air valve. Don't want the casing just the black valve motor.. The one I have has part number 2N08 on it. Al

Does anyone have instructions for setting up the fixed mechanical stops for the throttle body. I'm not talking about the TPS but specifically how the dampers work and the positions of the mechanical stop screws that are on the body. Thanks al

Hi, many thanks for that. Any idea what will simulate the sub-0x sensor. It's a 2 wire and the circuit looks as though it's acting as a variable resistor - current coming from the ECU to ground, which probably trims an op-amp or something inside the ECU to trigger that the cats...

Does anyone know if a 10K resistor to ground is an acceptable mod for not installing the secondary-oxygen sensors. Currently don't have them installed and revs are running around 1200rpm. Regards al

Don't know the sensor model, it was standard fit in a 93 reg car. Fully in tact and running well before I took the engine out for transplant

well, I checked the pulses per rev of prop-shaft today. I've got a 2 pulse system when measuring SP1. That is 2 transitions from high to low. Not sure if the 4 pulse means 4 transitions (leading and trailing edge) but mine is definitely a 2 pulse with 4 edges! changed my speedo to...

Just an update for a mod I did some time ago on oil take-off plates. Tried for ages to get various adaptors to seal but always had a niggling dribble of oil. Bought one of the items of this site, no joy. Bought one of the items from the Australian brotherhood which had been adapted to...

I've read on here somewhere that the SP1 sensor which drives the instrument cluster is a 20 pulse hall effect. Is that correct or is it a 4 pulse system. I've been trying to get an aftermarket speedo to operate and it hardly moves whilst I'm testing it on axle stands. Waveform looks nice...

Does anyone have the part number of the speed sensor #1. Thanks al

many thanks for the info al

Does anyone know what the bearing number for the tensioner pulley is. Load squeal needs replacing! thanks al

may tanks for the quick reply, such appreciated alun

Hi, what's the oil pressure readings expected from a 1uz at cold and warm. I tend to get around 95 psi when cold 68 psi when hot Is the starting pressure high Al

Can anyone tell me what voltage level the ecu expects from the speedo signal that's buffered by the instrument cluster. I know it's a 12v pulse from the sender to the cluster, does the cluster output generate it to a standard 5v logic level or is it still left at a 2 volts clock pulse...
