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.
Q': 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)
A: True the calibration resistor is not used in our wideband controller implementation, calibration is done trough adjustment of the calibration constant until your free-air o2% matches 20.95%
