Is there any Difference between s13 ECUs?

[Ezzo]

I tryed to search for it but the only threads I could find were about the Auto ECU swap to take out the speed governer. But I was wondering if Nissan changed the fuel or spark maps between 91 and 93 for the KA24DE. Do ither of them run ritcher or leaner? any difference whatsoever or did they keep the same tune all 3 years?.

Yes besides there being an auto ecu there are different maps that all depend weither or not it is a FEd or California ECU. Through the years the fuel maps have changed slightly but I believe that they are all minor changes. I believe the 91 Auto ecu is the most aggresive for our 91-93, 5 speeds I can't remember if there was any significance between the CALI and FED ECU MAPS. DeviousKA would defenitely know the majority of the tunes that are available for our ecu's....

i believe he said they were the same

the difference is actually between auto and manuel ecus. autos dont have a speed cut, but they are also a small amount leaner in something like the 2k to 3k area. so it'll make a little more low end for your automatic

now this is just what i remember reading from deviousKA. i wont ay there arent any differences (except cali and fed) but the only noted difference in fuel maps is that small area in auto ecus. so its not worth it really

Ok, figures all of that out for me! I have a 93 manual Ka24de ecu siting around and I didn't know if I could put it to good use. Thanks for the info guys
