Cefiro Diagnostics Plug?

[Chris_A31]

Can anyone tell me what type of diagnostics plug came with the cefiros (rb20det silver), the newer nissans come with OBD-II plug but im unsure what is in the ceffys?

Cheers, Chris

There is no plug as such, just an LED and a potentiometer on the side of the ECU itself. The procedure is the same as for the S13 (or at least it's the same as the CA18DET S13, I have no experience with the SR20 ones)

you can buy a r32 diagnostics plug and wire it into the ecu if you were really keen.

been don e before.

A31 ECU's don't support Consult style communication, you have to rely on the old long flash short flash LED error codes.

its been done before.

What does this achieve other than the convenience of not having to unbolt the ECU to get at the diagnostic codes?

the fact you can plug a carman scan tool like the one we have at work, into it to access the ecu using a hand held computer

well when i was getting my remap done the diagnostics plug was used to keep check on all the cars vitals so i would say it could come it pretty handy.

plus theres a few digital style gauges around that can only be plugged into the diagnositcs plug.

like i said if you were really keen......

Is it the Greddy informeter that plugs in the dianostics plug? Also the nistune remaps use the diagnostic plug.

I thought nistune kit just replaced the diagnostic LED and potentiometer with a USB connector on non-consult ECUs.

yeah i thought Nistune daughterboards came with a USB port that you have to drill a hole in your ECU housing to get to?

my cefiro was rb20 and used to have a diagnostic plug under the drivers side just above where your legs are, it did not fit the tuners plug so when i put the 26 in i soldered in a r32 gtr one straight into the ecu, it is only 6 wires, i have the wiring diagram if you need it. the new rb30/26 is almost sorted now, hope the 32 gtr computer will run it.

Well considering the R32 ECU is direct plug and play into the A31 loom, just use an R32 ECU and install a consult port. As said it's only 6 or so wires.
