^ i don't think that "AT" has anything to do with it. an OBDI JDM P13 is all the same, just like your OBDI F22b1 ecu is the same whether your auto or 5sp since you have a separate tranny controller for the automatic. it wasn't until 96/OBDII that the ecu incorporated the auto tranny controller in it.

 

Isn't the ecu suppose to send signals(such as vehicle speed and rpm) to the auto's tcm? How come most sites sell obd1 h22a swaps with different p13 ecu's? I thought it was the newer hondas that had the tcm incorpated into the ecu. I'm starting to get confused here.

 

yes it is the newer hondas starting in 96 that have the tcm incorporated into the ecu. i'm not sure where the tcm gets it signal from, maybe it's gets from the same place the ecu does or it's connected to the ecu. it was a while ago when i installed the vafc when i was f22b1 powered and still automatic but i think there was a harness connecting them.

i was never asked what ecu i wanted with my swap, i just said i wanted a 92-96 JDM motor and i knew if they sent me the right stuff the ecu would be the right one. i have never seen a site ask for different JDM P13s for an OBDI swap.

edit:i just checked out hmotors and they sell USDM and JDM H22s so maybe they asked you if you wanted a OBDI JDM p13 or a OBDI USDM p13 which would have different programming. otherwise they should always be sending the ecu that is appropriate for the motor your buying. i'm guessing since you bought the long block only, this why they asked you. either ecu would still work.

 

Thanks for the input. I guess I was a bit misinformed and my long block did come with a flex plate. I hope my h22a ecu is toast cuz if not, it means the shop that installed my motor doesn't know what they are doing.
Wish me luck!
