Hey I have a 89 Civic LX with a 2000 b18b and it is all running off a 90 integra LS PR4 ECU and wire harness. I was having troubles with the factory tach surging above 5k rps, like it would just bounce up real fast! So i figered fuck it, I would just install a nice sport comp 5 inch unit and that would take care of it, well i hooked it up to my MSD box, and I am still having the same problem, it sux because when it surges into the higher RPM's, it causes the shift light to come on and i am only at like 5500! If anyone has any ideas let me know, Thanks, Frank.
