the A/T S15 is only different for about 5 pins, 4 extra for the actual AT portion and one relabeled. Some of the maps might be also different to compensate for the "slugginesh" of the AT transmission. I also think that the S14 didn't come with VTC, so that will definetely will be a factor if you were to try to run your engine with the S14 ECU. I would definetely get the specific one that you need.

Try contacting JDM engine retailers, forum sponsors, etc...sometimes they might even have one sitting around for cheap....


Correction: S14 and S15's did came with VTC, my bad....
