ok heres the problem the guage dosent jump at all its moves around a little but
dosent jump around at all

i put the wire to d14 on the ecu

my car 92 vx w/ b18c1 chipped p28

my friend said i had to switch a wire for it too work is this true if so which wire

i know this guage is basically a light show but it was in the car when i had it and when i did my swap i took it out and now it not reading like before (which was a long time)

jas0n

hrmmm cant figure anything out

maybe your o2 isn't working. try switching to a 4 wire self heated o2.

jas0n

yah well i have a o2 off a gsr

another problem light came up and i got oxygen sensor it only comes on rarely and its seems to be 3rd gear or higher still trying to figure out why soo its hard to find out if we fixed it or what not

jas0n

i think it might be my o2 sensor i might need a new 1 any other ideas?

Check all wires, esp. ground. Are they setted properly? Did you tap the D14 wire, or just strip and eletrical tape it?

If those are good, then try replacing your o2 sensor, this might also be the case for your 3rd gear lag.

jas0n

the wire is done good i even solder it cause i thought that was the problem

Its probably the O2 sensor. Damn, those things are expensive .

boostin b16

just break down and buy a greddy a/f..............it comes with its own o2, relativly easy to install(just remove secondary o2 untill you can have a bung welded, and its the most accurate non wideban on the market...........i have one, turbo 8 months at 14psi daily just a/f and no prob!

jas0n

im ok what with i got

Autometer is fine at WOT, gives good readings then. Where else are you majorly concerned? At idle, who cares how rich your running at idle.

HondaCutter

you can get a 4 wire o2 sensor for $60 at oxygensensors.com

what does your gauge do when you are just driving regularly??? ex...stay rich....or what?

jas0n

moves around a lil bit in rich some times go to stoich

degooser

hum...i am not sure if this is going to help, but my chipped p28 always runs in open loop when i am driving regularly.....(stays in the rich section and moves a little around in there, I get horrible gas milelage!)

I thought that my A/F gauge was broken when I first swapped my motor, but now I think its the ECU program..

have you had your chipped p28 in for a while?

jas0n

nope just got in chipped it started to jump around a lil bit at certain times

but not like my other friends with a p28 chipped his jumps from side to side

he said he had to wire something different to get guage to work right
