Fields sfc controller

I have on code 17 for vss no other codes, and the Fields kicks in the v-tec

when it does there is a loss of power

the A/F gauge says the fuel is rich when the v-tec crosses over..

any ideas on why?

thanks

 

Maybe because you keep putting a dash in VTEC.

Seriously, its probably because the feilds forces the car into VTEC, but the ecu is still running on the low cam ignition map. I have no idea why youre running rich though.

 

I did not know that the ignition map changes...

sounds like I should tackle this vtec issue after the vss issue is fixed then..

thanks.. for the info

 

i think a vss cel would cause vtec no to engage

 

the cel does stop it from engaging with out the field SFC... The Field SFC engages the vtec
