ShiftVQ35

I am in the process of hooking up a wideband that has data logging inputs. It has 6 inputs which 2 of them are speed and 4 are analog. To those that have a wideband that has data logging , any suggestions on what to hook up to it ?

Did this device come with a manual?

ShiftVQ35

yes it did. according to the manual a compatible speed input is a pulse which switches between a high voltage and a low voltage. high voltage is between 2v-25v and a low is 0-0.8v and a analog input is a voltage between 0-5 v. the device is a plx r500

what kind is it?

ShiftVQ35

the wideband is a plx r500. BY looking at the fsm, i can hook up the maf and the tps. Both of them are analog signals.

I hooked up to MPH/ECT/RPM/TPS/MAF on my PLXR300. FSM + common sense = FTW.

ShiftVQ35

which pinouts did you use if you dont mind helping? fsm owns me haha. howevr i came up with pin #83 for tps and pin #62 for maf. thanks for the help

IMO, the MAF input is useless because the voltage is not a 1:1 relation to airflow. Not sure which ECU pin I used, but it doesn't matter since well, it's not a good relation.

The speed inputs (RPM/MPH) are very useful though.

alright i got 3 analog signals which are maf,tps,and ect. Tach is a speed input but what about mph? according to the fsm it stays at 2.5v but isnt it suppposed to vary?

L.M.L.

seems like you are in trouble

ShiftVQ35

Tach and speedometer are speed inputs and the rest are analog.

got it all hooked up today. time to log some data.

If it's a speed input, it needs to be a frequency, not voltage.
