Simple question, and hopefully someone knows:

Does the Evo X OBDII output include manifold absolute pressure data?

I know these cars are Mass Air Flow based, but I thought I noticed a MAP sensor on the intake too.

Anyone using a PLX Devices DM-100 OBDII scan device?

 

Yes. You can read MAP via OBDII

 

Is anyone using the PLX OBDII mulit gauge on the Evo X?... how many ACTIVE parameters are there.. ie active display info can we see?... can wee see boost, oil temp, water temp, exhaust temp?.... I'm currently runninng Defi's but wld prefer the less gauge look so I'm looking at teh PLX OBDII system... any comments?

 

It sounds like boost or at least MAP reading is an available output. Water temp should not be an issue since this is a standard OBDII output.

I have not seen a factory ECU that actually has EGT sensor input/output, however some of them do output calculated EGT over the OBDII port. If available, EGT (exhaust gas temp) output on the OBDII port will not be terribly accurate.

No oil temp.

They benefit of using the PLX Devices OBDII gauge is that you can daisy chain in extra sensor modules and have them display on the same gauge. So whatever info you can't get over the OBDII you can simply add a PLX sensor module for (i.e. wideband AFR, EGT, oil temp, etc.)

 

Thanks for the info guys. I was looking at the PLX device and also the GReddy Informeter.
