Testing the Sensors
I've bench tested the NTC sensors and they work in pots of water at varying temperatures.
I need to add a IAT sensor to the manifold somewhere. Found one in a scrappy for £1. It works nicely.
The wiring is all in now, except for the wideband lambda sensors. I need to do some work on the exhaust before these will work.
I have recompiled the firmware for the non-GM CLT & IAT sensors. Need to refine the calibration more as it isn't quite right.
TPS just worked, which was nice. I can cope with this happening...
'''Wideband Lambdas
I'm fitting 2 of these - one for each bank. (I understand I need to modify the firmware for the 2nd to be supported.)
I've just looked at the manual for wiring them up. Should the cal resistor in the wideband sensor be connected to anything? It isn't in the diagram (it's on pin 2, and this appears N/C)
