Vafc cel...
 

Im going to check my friend's car tomorrow to see what cel its throwing but here is what he told me...

He installed a vafc on his d16z6 obd1 p28 civic...his car is stock for the moment
---> work fine ( he did solder all wire and tripple check all connection )

Yesterday he installed 450cc dsm injector with 10watts 10ohms resistor... on his vafc he set them a -46% because 240/450 = 53% so 100 - 53 = 46 then 450 - 46% = 240... like stock injector... right?

He started the car... idle fine, going for a ride... seems cool. Then he went on the higway "test" is car going 60mph...fine going 100mph went 110mph fine but after he release the throttle cel lights up... if he close the car the cel is off but it lights up most of the time when the the throttle is at 0% open... in 4th and 5th gear...

what could cause this? I might save some time...
