My tachometer goes f'king NUTS after 4k rpm....waving all over like an idiot. And this only happens when I'm running my s300 (Stock 2001 ITR basemap).

Stock ECU = no problem (I no longer have the P73...so I've tried the P2T and P72 both work fine..no tach problems)

S300 = haywire

Engine: 2000 B18C5 stock specs(was boosted...rebuilt back to stock)

I've never had this problem before...is it just the stock itr map?

It's not a problem with the ECU or the s300. The issue is how the igntion system is wired in the newer cars.
