just got a m300

i got the 02 sensor and airfuel gauage
and the wiring

is there a online page for the details instructions for wiring?

I have the same one and need to know where to wire up the gray and white wires in the stock harness to use the narrowband out put for the ecu and wide band for logging.

 

on obd1 ecus the grey wire (narrowband signal out) goes to pin D14. When tuning, switch to the white wire (wideband signal out) so you can log the wideband reading right in the tuning software.

I love my PLX M300.

 

can i use it for street/dyno tune for my p28 on crome pro?

i want to test it out on my ek3 now with the d15z6 vtec-e motor
im going to be puttin in a b18c4[gsr motor with lsd] in a few months

my d15 motor is 0bd2a and has two 02 sensors
1 is a 4wire 02 sensor near the collector
and a 1 wire 02 sensor in the top of the header

which 02 sensor do i swap over with the wideband sensor?

and what wiring will be needed to do

 

Replace either and wiring like the man said. I have a 99 coupe 0bd2b-obd1 jumper makes life easier. On my p75 for my ls no problems.

 

you'll want to have the wideband o2 before the catalytic converter, obd2a the pin would be D7 for the primary o2 sensor.

I've used my PLX M300 with a chipped p28 and a moates Hulog datalogger and Moates Ostrich for real-time programming for 3+ years now.

 

do u need to keep the moastes/ostrich in the car all the time?
or just remove from the ecu?

 

no, you can burn the file to a chip once you're done tuning. But you CAN keep in it the car full-time, i know a bunch of people who do this.
