figured, i might as well, right? what's another 500 bucks? PLX M500 is what i got. it uses a cheapo bosch sensor. the M400 uses the bling NTK, but its a lot more moeny for each sensor... so i figured, what the heck, get the cheaper one. i can always replace them cheaper when they go bad. any who- this is what it is: #1 reason why i bought it: integrates with hondata http://plxdevices.com/PLXApp002.htm #2: easy to hook up it seems... no worse than a vafc. #3- its WIRELESS so now, i don't have to be like all the other nubes on the dyno runnign wires through the passenger side door to the laptop. it works much like a wireless home network. two cars with antennae on either end. #4- has its own datalogging software. also, will display other features/readings, and has the option to display a custome BG on the laptiop if i so desire... customized, and with gauge readings: Looks easy enough to connect it all too.... Has 6 input channels... so, i can effectivley gain "gauges" as well... and even though hondata datalogging supports this as well, its nice to compare. check this, they even give a nice chart to say which type it is on the ecu pinout diagram: (pulse/voltage) http://plxdevices.com/ECUDatabase/Honda_Ac...L_INT_92_95.pdf #5- supports narrow band as well as wideband. although, once im tuned, i will never even be reading the narrow band to the ecu at all (hondata will have my set map, and will not take a readin anyway) but, it does suport both, so if i need an emergency p28 swap or something, it can be done #6 option to go wired. if for some reason the wireless is getting interfeerence, they make a quick adapt cable. basically unplug the antenae and replace #7 - cheap sensor. full tech specs: http://plxdevices.com/M-Series-Controllers...0_TechSpecs.htm i think its a steal at 500 bucks. reaction to the thing after it gets here and installed thoughts?
