Speedo/Vtec not working.

So I have a 97 ex coupe with a b16a2 swap in it.. The speedo stays at 20 mph or jumps around sometimes I have no check engine light at all until I try to go over 5500 rpm which is vtec engagement.. Also I just replaced the speed sensor in the transmission because I thought it was that.. any help would be appreciated

Give details about how you did the swap.

Also, post the CEL codes and the ECU code.

Re: Speedo/Vtec not working.

Does the odometer roll steady and accurately? If so the problem must be the speedometer head itself, since both functions use the same sensor and wiring.
