CEL keeps coming on..
I just recently installed a Fields Vtec controller. wired up everything right. vtec kicks in at 5200. eveyrthing works fine. But if i hit vtec in 4th or 5th the CEL comes on for a code 21. Vtec spool solenoid i believe. but if i shut my car off and turn it back on the CEL goes back off. Y is this happening?

Checked all the wiring.. all connections are made and very secure. everything is electric taped to prevent them from touching each other. Im running a Chipped P28
