I'm planning on tuning my car and I was wondering what would be the optimal AFR for DSM's.

 

[anconover]

sx fpr is the choice of fpr mostly, diamondstarmotorsport.com has it + a full installation kit, or u can peice ur own.

No, no....not FPR...AFR as in air/fuel ratio. Anybody know?

12.8 a/f with a .90 - .95 volt 02 at wot. WATCH the egt thats more important. air fuel is just that. its more important too tune around the cylider temperture doing wot runs

 

[boosstboy]

sorry 12.8 is the highest, 12.1 - 12.7 is the preferred desired ratio

 

[Dsmman]

11.5:1 to 12.0:1 is a safe range. That's usually what I shoot for.
