B9B vs. X2J

[FOMOCOTOSHO]

I am finally buying my first Gen I in a couple weeks and I had a couple q's.

I was doing some searching about the different ECU's and was wondering does the X2J provide any advantage as an upgrade to a stock or relatively stock '89 with the B9B? From what I read the X2J is better if you are doing any tuning because it processes faster, but does it change anything as a simple swap out?

I couldn't seem to find the answer from the other threads that came up when searching.

Thanks for your input

Yeah that's the only thing! Unless somebody was telling me something wrong
