Going TT. How to tune ?

[nightdiver]

Im going from single turbo to twins and since there will be two downpipes, where should i install the WBO2 ? Is there an option that uses two sensors to tune that right ? I think monitoring just one bank is not safe
Got any ideas of what to do ?

Plenty of NA motors w/ dual exhausts run a single WB in one side or the other. No biggie.

If you are worried about watching every single cylinder, maybe you should get one of those EGT setups.

I recorded 1050*F when i drove it yesterday with 90 miles and 1450*F @150 mph (22psi of boost)
How do they tune the sequential system ?

If you have an EGT that looks at each cylinder, you can add/subtract fuel from the cylinders to even them out (assuming your thermocouples are giving accurate readings). If they are all hot, then maybe you need to richen things up and maybe you need to advance the timing (usually the former).

Is that what you mean?

My EGT sensor is on the downpipe. Advance is 35* in vacuum and 27*@15 psi and drops to 25*@30 psi
I run Julios kit with pure meth and two 15 injectors
Intake temps are around 54-55*F under high boost
I think the sequential system doesnt worth the trouble to get in.
I mean 6 sensors and wiring ,and try to monitor and datalog it.....ok im lazy
