We had the opportunity sometime last year to tune a Miata that had a turbocharger hanging off its exhaust manifold. Boost can really make a “chick” car that much better. This Miata was running terribly bad and we offered to lend our services to make it even better. On its first visit the turbo was running off the base wastegate setting of around 3-4 psi. We cleaned up the ECU maps\settings (Megasquirt) and ended up with:
You can see how bad it was running (green run) to a much improved performer (red run). Boost peaked at 3.8 psi.
So fast forward and back up to last month. The customer purchased the add on boost solenoid for more well, you guessed it……..boost! Once you have a taste its like crack.
Needless to say this thing hauls for as light and nimble as it is. The boost gods can rejoice. An increase of 5 psi for a total of 8 psi. Specialty-M? J\K! Zs rule!
