I just installed my vafc and had everything tuned up and we dropped the X-over point to 5000 and leaned it out a bit over the powerband.. One problem though, whenever i go around a corner or if there is any lean on the car or if i am hitting a bump, VTEC will not engage... I also have a VAFC harness which allows the harness to plug and play with my ecu, could i have a loose pin??

Plaese help, i have a autocross this next weekend and this will totally screw me up!!

Also is it good to reset the ecu every once in a while??

Thanks!!
Greg

 

oil level ok?

 

oil level maybe. I hate running out of vtec.

 

Seems pretty low, probably the problem, ill get some more tommorow..

Thanks for the help, i owe all you guys a

 

don't spin bearings. Its very expensive

 

its a wire connection. perhaps on the "harness"

 

This might seem like an odd question, but did you tune it on the dyno? Or did you just drop the vtec for ***** and giggles? If it's not the connection, you might want to tune it on the dyno, you could be doing much more harm than good.

 

check the grounding wire on the VAFC to the computer.

 

Yeah, also make sure that the two grounding wires are at different places on the ECU ground, one further up stream...Also make sure your VTM wire is secure...otherwise, I'm with everyone else...sounds more like oil.
