Looking for a bit of advice for my 98 manual R34 GTT, I keep having the speedometer and rev counter drop to zero followed by the TCS, Slip and CEL light up. I've recently upgraded to a nistune ECU and can see I'm getting the speed sensor code. The issue is intermittent and when driving the clocks return to normal or drop at any time.
I've replaced the sensor with an OEM part and fresh box oil with no success in getting rid of the problem.
Could it be that in disabling the speed limiter within nistune will have caused this issue? Anywhere else I should look?
It's been fine this past week in the warmer weather but now it's cooled down a tad the issue has returned.
Any help would be appreciated!
Thanks!
