I recently purchased the PLX R-500. I went this route since I don't have any mechanical gauges yet and I love the feature set of the device. I plan to dash-mount it so that I can keep my eyes on the critical values easily. I also plan to use it as my primary boost gauge, but being electronic, I was thinking that the refresh rate of the diplay would make it near impossible to detect boost creep and spiking which is why I was considering also getting a mechanical boost gauge. I plan to mount in-dash with an oil fuel and pressure gauge as well. It's between either a mechanical boost, water temp, or fuel pressure gauge. Opinions?

 

Hi,

Do you know what there website is, sounds like its very nice.

Thanks

It's www.plxdevices.com. Anybody have any suggestions. Still unsure.

 

I got a reply back from PLX and this is what they said

"The Lancer Evo uses a MAF, so you'll get air flow instead of pressure if
you interface to your stock MAF sensor.

Here's more info.

Lan evo 8 and 9 uses the same sensor


For boost you can connect an aftermarket MAP sensor to the R-500. Here's

It appears we have to buy a MAP sensor to get the boost part working. What I'm wondering now is what does the MAF tell me and is it worth monitoring?
