For those of you with SH ludes, does your ECU control the ATTS at all? So if you swap in another ECU, will the ATTS still work?

Do you know if its the same with 4ws?

Basically i wanna see the effects of a USDM ECU on my car, and am considering keeping one if it works... but dont wanna loose 4WS.

thanks

So what are you asking here? ATTS or 4WS? 4WS can be kept if you move to the USDM ECU. I don't know a whole lot about it, but I know someone here with 4ws SI and a JDM H22a swap who uses either the JDM ECU or an USDM P13 ECU that I sold him, depending on what he feels like using.

The JDM ECU gives him alot of top end power, but the idle and low end seem to be pretty bad for some reason.
