Ecu Question?

[project_dori]

i opened up my ecu`s today, one is a factory turbo a31 cefiro ecu and the other a turbo r32 skyline (i thought) i have opened 4 ecu all looking like the left hand ecu in the picture but the right side ecu in the picture has a totally different layout (no second board) any ideas on what it is i cant go off the casing as someone has changed it all the numbers are different the internal number is MEC-R531A

got me stumpped...

HI, Stick with your original ecu, R32 are different in the electrics department when it comes to wireing ect, Before i up graded my A31 RB20DET i had a dynotuned APET chip fitted to my ecu, Wow unbelieve able power, at that time i ran a 5 speed , modified exhaust and a good pod filter n adjustable blow of valve, After fitting and checking the tune i took my cefiro for a drive and it freeked me out how much faster it was with sweet f all done to the engine, I have all of the specs on the APET Chip and i still have that same ecu, I will sell it for $400 nz if you are interested, I run a RB25DET Neo Now, Regards Jamind

Stick with the factory r32 ecu if its complete and untouched, the a31 ecu basically runs a heart beat of lean in the mixtures so its not so stable

Agree with Dan, A31 ECU is junk compared to the R32.

I personally had issues with the A31 ECU not being able to accept a Toshi chip which the R32 happily takes.
