hey guys just picked a 89 crx si with obd0 b16 swap. running pw0 ecu. acts like its in ssafe(limp) mode. iacv needs changed surges but no check engine light vtec will not kick in at all. rpm wont pass 4g just curious on any ideas. gonna change iacv tomorrow.

 

Any codes from the ECU? Check your TPS, mine went into limp mode with it not working properly.

 

no cel it popped 17 when we pcked it up but it was the speedo cable noy all the way in fixed that today. no cel since

 

Do you have access to another ECU?

What is the max you can rev?

 

4000 rpm

 

after teh code 17 did you reset the ecu?
