1988 Nissan Cefiro Ecu Problems!

[rob_mr1200]

i got a mines ecu from an r32 but the bloody connections r different and the ecu i got is bigger..

can anyone help me with wat i can do or anythin?

[Moodles2]

What engine do you have in there, RB20, RB25, CA18, SR20 etc?

[daisu]

As long as you have an RB20DE or DET any R32 ECU should fit.

[rob_mr1200]

well i have an rb20det..

but i got a r32 mines tuned ecu but the connection for the mines is bigger than the stock one :S

its really weird because pretty much everythin i buy for it that is off an r32 doesnt fit coz the plugs r different.

The RB20 in some A31's are different to R32 mate and the ECU in the series 1 isn't interchangeable either is the ignitor, CAS etc as the plugs are different. You can either change the wiring harness/ignitor to run the 32 ecu or you will have to get another A31 ecu

Sounds like you have the eariler Redtop HR31 ecu \ loom in there, I would personally change everything required over the the silvertop R32 loom \ ecu and go from there

but its the stock engine and its the silver top rb20det..

would it just b easier to buy an rb25 with all the wiring and put that in?

A31's wiring harness is different to the R32 wiring harness for silvertop mate depending on what year it is so not necessarily running a red top loom.

Well it depends what you want to do with the car and what exactly is your problem in the first place to warrant a different ecu cobber???

nope you need a cefiro ecu or you need to swap in a R32 engine harness to use r32 ecu (or pinswap a header plug).

wat u mean pinswap a header plug?

i new cefiro parts were hard to find but i didnt know they werent even the same as the r32

typo replace a with on.

cefiro has no consult wiring etc.

Spot on Bevan, im glad someone agrees with me

I was of the impression the ECU's were still swappable even if the loom had the square shape connectors.

The ecu plugs are different sizes so not interchangeable unless you have a R32 wiring harness installed to run the 32 ecu.

[rob_mr1200]

how hard would it b to do a pinswap?

coz i got a mines ecu i just think it would b a lil bit of a waist sellin it lol

Those Jap tuner ECUs are really meant to be used with 100 RON fuel which we don't have.
