JWT ecu in ka24det running weird

[s13_ka24det]

Need some help on this one again. My car runs fine with the N/A JWT ecu programmed for 370cc injectors w/stock MAF. If I use my JWT turbo ecu programmed for 370cc injectors w/stock MAF on the same car, the idle jumps and revs as if running too rich. Any suggestions?

So if you simply swap in the NA ECU it runs fine? I'd say obviously the ECU is the problem. Call JWT and tell them the problem you're having.

Anybody know how to test a ECU if it is bad?

do you have a wideband and something to see timing with?

my jwt ecu ran very lean at idle. once i added fuel with my safc it was perfect
