Has anyone used daughterboards in their car?
There is a guy here in Perth who is in the Silvia club and he makes daughterboards.
He says that he can make them for RB20s as well as the SR20s, and that he can heaps of stuff with them like remove speed limiter, change rev limiter, change fuel maps etc etc.
Also apparently you can tune the fuel map to every 125th load point compared to the safc's 250?
Would one of these daughterboards be a good buy?
They cost $100 from this guy in Perth.
