I have just recently gotten my turbo setup installed and tuned. (setup is in my sig)
I am using a p72 obd1 gsr ecu in my 97 prelude, and it was tuned first with uberdata, which worked great until there was no vtec engagment, and then we decided to try chrome which led to the same problem.
Anyways, the lower cam makes great power but wont switch over to the higher cam, and I currently have no vtec, and it sucks. Any suggestions would be greatly appreciated.

 

Either one. Turn off the vtec pressure switch in uberdata or crome.

2) Check oil level
3) clean VTP screen

 

my oil level is full, and my VTEC solenoid is also good and it worked perfectly fine before. Could my p72 be a bad ECU or would the whole thing just not work?

Try just disabling the vtec pressure switch and see what happens..
