L6 management No Spark ? MAP voltage wrong & PF02 ?
I am trying to get my ZT S1 running, It is running cosworth L6 with wasted spark on a carloom bespoke loom, I found a list on here of voltages and resistances to check that someone had posted up, very useful, i found that it should be a PF01 throttle position sensor and I the one I have has PF02 on it and the voltages when checked are all wrong, 4.76V closed and 4.76 when throttle fully open, and if I unplug it the voltage is 4.96V, another thing I found is that the MAP sensor should be greater than 1.8V (i think) and both of the MAP sensors I have tried both read 1.55V when checked. What causes the MAP sensor to read low and where is the best place to get a new PF01 from ?

I've found that life I needed.. It's HERE!!
Different map sensors (2-, 2.5- and 3-bar) produce different voltages at KOEO.
1.8 volt is for a 2.5-bar sensor (std. Escort Cosworth). You seem to have a 3-bar sensor, and 1.55 volt is very normal on a 3-bar.
