Best system to Monitor AF and Fuel Pres

[Tim]

I have a lot of money invested into a NA Stryker package on my 2002 RT10 and I want to monitor fuel pressure and AF ratio. The PLX Gauges that ties in on the OBD reader looks like the Ticket to have and I am wondering if anyone else is running this or something similar on their cars?

Thanks

While tying into your OBD II works, most who are serious about monitoring Air/Fuel Ratio use a seperate measuring device. If you have an O2 sensor start reading incorrectly, tying into the OBD II system for the Air/Fuel ratio reading would be of no value.

The OBD output on a viper has no fuel pressure and the a/f is not a wideband, therefore useless.

Look at Innovate and their DL32 - I am logging dual widebands, fuel pressure (from a 0-5 transducer) and a handful of other oem sensors taken directly from their 0-5 outputs. If you are serious you do not use a gauge to measure a/f at wot - it does not work. I use the Innovate gauge to monitor closed loop a/f and to actuate the logger.
