Hi does anyone have a manual p13 ecu ?

maybe best get part number off the ecu in the car so you get the right one.

Nope.
They're different for manual/auto and variant of H22 engine (different map for different compression ratio's).
There are also 4 and 3 pin versions.

So it is a JDM H22a P13 manual ECU. I think this is the 3 plug one (no tcs)
Part number 37820-P13-N00
so basically any JDM P13 for 4th gen manual with H22a vtec engine.as the 4 plug P13 ecu with tcs ecu should also work.

If you open your ecu up you should be able to check for any damage visually - you could post up some photos of the circuit board.

Great I’ll try and get it opened up tomorrow, there is so much more to these cars than the old 70s and 80s that I’m used to

may seem that way but preludes are quite easy to work just a bit daunting at first.

I had a 5th gen a few years ago and loved it, now my boys older we got this one to work on, get up to scratch and then start modding together, his super excited to have it running again

Ok managed to get a picture of the inside, tbh I have no idea what all this does in there
