Individual Cylinder Correction

Which is better to use: oxygen sensors or exhaust temp sensors?

Should the sensors be screwed in or clamped to each runner?

Can the RB25 PFC with FC Datalogit support 6 extra oxygen/temp sensors? If not whats the best way to monitor the sensors at once?

Where on the exhaust manifold is the best place for the sensors?

I have an Rb25/30 with greddy plenum and high mount 6boost manifold (bare atm) thats looking for 350rwkw in a R32 GTST.

either is OK although wideband 02 sensors are bester. But either way you need 6 bungs in the manifold, 6 senders and 6 gauges. PFC doesn't run them you just monitor the outputs from each gauge.

02, without a doubt, but its a cost thing. K type are like 50bux each. Then you need a loggin box for a few 100, as the 4 inputs on a Datalogit's not enough.

6 LSU4's and what ever controllers your using, is significantly more.

The 02 senders would be in the runner, close to head, prolly needing a heatstink. Ud need bungs welded in.

Thermocouples can be threaded like the 02 or a wire thats brazed? not sure, on.

I assumed bungs would need to be welded thats why the manifold hasn't been ceramic coated yet.
