I swapped a JDM B16a into my 90 Crx HF. Everything works fine except vtec (imagine that). I've searched and searched and double checked my wiring from the ecu to the solenoid and pressure switch. I'm using a p30 ecu and it's throwing 2 codes. Code 10 (iat temp sensor) and a code 17 (vss). I'm still using the stock crx cluster with cable tranny. My speedo works so I'm confused as to why i'm getting the 17 code. I know the ecu is supposed to detect certain speed to enable vtec so I'm wondering if thats why it's not working. Any ideas as to why I'd be getting the vss code with the speedo working? Any help is appreciated.
