S13 Blacktop E4 ECU vs #63????

[89Hatch240sx]

So ive been confused by this for a while.

I have a S13 SR blacktop with a E4 ECU. my other SR i use to have had a 63 ECU which was a blacktop also.

my question is what is the difference?

my old SR when i would hit rev limiter would have a VERY FAST rev limit

like Badapdaddadadpaddadpada ya know?

my current SR's red line sounds like a KA

Dun Dun Dun dun.

I just dont understand this... now before some buttholes get hurt IM NOT A REDLINE WHORE I rarely EVER touch my rev limiter.


im just wondering is this the reason for the weirder rev limit?

also i dont have a O2 sensor right now but its OBD1 so i dont see there lying a problem?

is there a difference? between the 2?

i also wondered what the diff was..i hope someone answeres

63 is an auto ecu
An e4 is a later blk top
I had a 62 manual and put a e4 ecu w no real diff
As far as the rev maybe cause 63 is auto..

What's your rev limit at cause a manual ka with auto ecu has no rev limiter.

^ correction. manual ka with auto ecu has no speed limiter. it still has a rev limiter..

E4 is the type x black top.

#63 is older version black top
