06-22-2006, 01:41 PM
Currently im running this ECU in my s14 with s14 sr
WC 23710-69F00

I need a spare for tuning purposes and found one thats supposed to be from Zenki S14 (same as mine) but has this code (mine has red label this one dosen't)
WC 23710-69F01

What are the difference in these ECU's, what do they mean? Will it be able to run my motor without any problems?

Im just trying to avoid the downtime of my car while getting the ECU re-tuned. Someone please let me know before i waste money on another ECU.

there isnt a difference that i can find, they are both from zenkis, both manual transmission, one may have been a zenki from like 95 and the other may have been a zenki from like 96.
