I have a p74 Integra GS/LS/RS ecu, and i want to know how to tell if it's a 5-speed or auto ecu. There are no stickers on it. It's hooked up to my hondata, that's in my prelude si-t. The problem i'm having is that i'm hitting some kind of revlimit at 6500 rpms. i thought we set the revlimit up to 7000 when setting up the hondata. Is there a way to tell for sure that the ecu i have is a 5-speed one? or would it matter?

 

here you go:

 

May bad, looks like P74s are laid out differently:

 

thanks for the pic, but what am i looking for on the p74 ecu?

 

At the bottom right corner, look below the socket. These are labeled RP. RP17 should be empty. That designates it 5 speed.

 

Thanks for the info!

 

So all you do is cut off those two black boxes and you've converted your ECU into a manual?

so I unsolder those 2 pieces, and my 94 ls auto ecu is a manual ecu?

 

No, don't do that. There is a resistor that gets cut. You don't need to take those transistors out.

 

what resistor do i cut then?
