So I recently put a gsr into my ek using ob2 auto d series vtec harness I tried to use the computer that came with the car which was previously B20V swapped I was told it was a p72 which had a sst chip in it so I purchased a Moates ostrich and have been trying to tune on Crome I removed checksum rom and I cannot seem to move the limiter from 4K I’ve tried deleting and reinstalling Crome I’ve tried flipping the emulator cord and it won’t move the rev limiter I have a p28 that I’ve plugged in and the car runs great revs out to 8K but just won’t hit vtec I know I’m going to get burned because there are multiple similar threads but everything suggested on those threads is something mechanical

 

There is something wrong with your chipped ECU setup.

Also I don't remember what the limitations are between crome and crome pro. You might need a blank chip to burn your tune to. I am not sure you can reburn without pro which requires a dealers license or something of the like.
