datalogging with a wideband

[derK]

i have my wideband hooked up and after trying to tune it without any sort of datalogging is difficult. So, i have a PLX m500 and i want to hook it up so that i can datalog my highway pulls.

I have 6 wires. 2 for speed and 4 for analog. Which pinouts do i hook these up to?? for sure 1 speed hookup will be the speedometer and the other i'm guessing injectors but which one?? 1&6, 2&4, 3&5?? does it matter??

and for the analog should i hook them up to the TPS, o2 sensor, air intake temp sensor and AFM???

Speed I would imagine are for RPM / Speedo so you can watch both at the same time (depending on gear etc) and the 4 outputs are if you have a V8... otherwise you use 3 of the 4... for your Injectors...

that is what makes sense to me...

I would attempt to find a manual however... they should have come with one.

The analog inputs can be used for any 0-5v sensor on the engine. You could log the tps or coolant temp, or even boost pressure if you have a map sensor. It may not be calibrated for each type of sensor, but you can monitor fluctuations or spikes once you know what normal looks like after cruising around.

ok so what does everyone usually hookup when they decide to datalog?? i'm still a little confusedl
