Knock Sensor, How vital is it in my H22?
Hello all.
Please forgive my ignorance. I will picking my 2.2 Vti (H22a 185bhp black top) next week. When I test drove the car, I didn't invoke the Vtec (which is at 5800 if my research is right). How would I be able tell if my car is running in limp mode? I have read on these forms that the rpms are limited to 6800, and you experience reduced perfomance. Are there any other indicators for a UK car (might be different to a US or JDM car).
Thanx in advance.

As far as backwards compatability, Ive tested a brown square type on a b16 obd1 ecu and it worked with no problem.
