I've posted this already, and I'm no longer boosted, but the FI forum is the most helpful here. So here it goes, I just got back my gsr with a b20 block with a mildly built gsr head with a new head gasket. Well Its throwing a check engine light, but I think thats because my speedo went out. Ok my car hits vtec sometimes, and when it doesnt it boggs like its getting way too much fuel, but I also noticed on my SAFC when it boggs the Vto comes on to switches to "on." I'm pretty stumped...help!! Thanks.

 

if speedo dont work then vtec wont work.... unless ur ecu is chipped and the speedo is disabled

 

i'm pretty sure if you are getting a check engine light the best thing to do would be to read the code

 

Im going in a little bit to run up so they can run it.
