so i swapped a 2000 non vtec obd2 engine in my 94 non vtec obd1 integra, droped engine in with stock harness and everything using a p28 chipped ecu.. problem is everything works besides rpm guage, only thing i can think of is that i swaped the guage cluster from the stock one to a gsr one few weeks back, ill be swaping it back in 2maro, but just incase that doesnt work, anyone with any ideas, cause i puzzled, i have done this before in a 95 civic with a 99 obd2 engine, no issues, let me know what you guys thinks...
