Ok my car runs but has no vtec engaging I'm running on a chipped P28ecu but no vtec I also tried to run different ecu but its all the same and check engine light comes on only if I gun the car to redline so when it came on I ran the code the first code was 22 vtec pressure switch I replaced that. Right away then tested it and another check light comes on which is code 23 my knock sensor so I'm bummed out but if anyone might know what's wrong with it please let me know thank you I really appreciate it......
