Thread: Tuning for a manual transmission

if it wont go above 4k then the pcm thinks the car is in neutral. like DH said adjust so that it thinks its in drive, or adjust the tables so the rev limiter is higher in neutral... but not sure if other tables are adjusted if the car thinks its in N. I suggest adjusting the harness so that the Neutral safety switch is properly connected to the pcm so that it sees if the car is in N or D(a gear)
