I know that I am alone with this "problem", but I want to tell their experiences to find. that can be set.

D14A4 with AT BOX S4PA.
S4PA same M24A. and so i use my 37820-P28-G51 for ECU. u dont need make any modification, just "plug and play"

NOW SOME INTERSTING
my friend R0NA. Make MiniME. D14A3+D15x (JDM) + P08 ECU. M\T Gearbox. He complate MiniME. No ERRORS. All Ok! but today he gave me my ECU for flashing and configure. 37820-P08-000. It's true clean JDM ECU for MT. but.... i plug in it in my car and go) without error. and with my AT. and of course VTEC. p08 work with our D14 lambda (1 wire, not 4)

So u can use EDM P28-51 and JDM P08-00 for u AT S4PA = 100% it work.

That is really useful info. Years and years ago I had questions from a VTEC-E owner with AT which I could not answer. He needed AT since he was handicapped in some sort of way. I bet there are more people wanting this info.

vtec-e, 115 bhp, economy vtec. not aggressive.
1. step before 3000 RPM 12 valve
2. step after 3000 RPM 16 valve

but i don't know when VTEC is turn on: after or before.

we have aggressive VTEC, and it turn on after 5500. a think for control VTEC-E need different ECU.


i know about head D15B with 2 stage vtec (2 solenoid)
1-12 valve (like VTEC-E)
2-16 valve (all D-SOHC engines)
3-16 valve with VTEC (our VTEC)

but for control for both solenoid neeed special ECU P2J, it have out put to both VTEC solenoid.

Good find! There must be a few ECU's that work from random engines that I guess it would be just trial and error to find them all.
