Doing a swap right now on my 94’ SI prelude. Original H23a1 to a 97’ h22a4. I’ve done my research and have almost everything I need, but this p13 ecu. Where should I begin to look? Any suggestions? Any help would be greatly appreciated.

Your going to need to use the P5M 97 prelude ECU with the trans computer and the SS trans. As there was never a Auto p13 in the USDM market!
This is my first time hearing this. So would it be easier to go ahead and swap trans To a standard?? The place I bought the motor from said he would sell me an entire trans swap for $1000. Then could I use the p13?

The H22a1 was offered in 93 as an option and like the GSR in 92 manual trans was the way they came.. of you do a manual swap the p13 would work or look for a JDM p13 Auto ECU .. another option is a P28 with a retune but will loose IAB,Knock sensor.

Really didn’t want to keep my Lude auto anyway. Just didn’t feel right. Lol. I was trying to find the most cost, and time efficient way to get the swap done. So I guess the next step is a manual trans swap, and the p13. Got the obd1 dizzy, and fuel injectors. Oh found a trans from the same place I bought the motor, entire trans swap for $1000. Thanks for the help guys, it’s greatly appreciated. The p13 ecu is a hard bugger to find. Any suggestions?
