I just ordered an h22a from tigerjap, and a rywire sub-harness for my '93 Si, and I was wondering about the p13 ecu. I noticed there's USDM and JDM versions out there...is there a difference that I should know about before buying either one?

I've seen someone sell their JDM ecu for a USDM ecu, for reasons they didn't make clear...so I'm wondering if I would need the USDM p13 to properly run my setup.

Can I get some real info on this subject before I buy an ecu? Thanks.

 

The JDM has a 118 mph speed limiter. USDM FTW

 

Ew. JDM p13 FTL.

I appreciate you telling me this before I saved the 10 bucks and bought the jdm version and realized the difference the hard way. Thanks.
