i bought a jdm h22 from this tiger japanese online place(not ebay). they sent me a bunch of stuff correctly but screwed up on one huge deal. they gave me an auto p5m ecu! i called them and they said theyed replace it if i payed shipping. wat i was wondering is if me using my stock usdm SH ecu is a bad thing? am i loosing power? Wat could result from this? ive been using this and it seems to be ok but car seems to lack power. thanks in advance and yes i kind of am sure of the answer i jus thought you guys could be more specific to wat problems if any can be caused and how much power im losing.

 

you can convert it to manual.

 

You shouldn't have any power loss problems because of the SH ecu. Did you keep atts?
