91 std with mpfi swap and si tranny. car ran fine until swap. using a zdyne 1 wire for vtec. ran it to a8. when i tried to start after swap, i hear some clicking by the vtec solenoid, the code light on my ecu (pm6) freaks out flashing rapidly and constant. it sucks all the battery power and car does'nt even try to turn over.

 

I'm not real up to date on the whole Zdyne 1 wire managment thing. But If i were you I would have converted to obd 1 and used the p28. But hey thats just me and my .02. Hope everything works out for ya

 

if you're not up to date on it then pick something you are up to date on for your first post.
