Hello,

I will be tuning a FRS/BRZ that has stock MAF, 1000cc injectors and 2.5 BAR map sensor. My question would be... Do I need to do a map re-scaling or do I tune it same way as a stock map sensor were as long as I do the correct MAF scaling the AFR's will be the ones I demand? The car will make probably 10psi...no more. I wish the stock MAP was available but is not.

Thank you,

Paul

If I understand correctly, you have already rescaled to accommodate the 2.5bar? If so, then you need to make sure that your fueling, timing, etc.. tables are rescaled to accommodate positive manifold pressure.

But yes, after rescaling the sensor multiplier and offset you should just be able to tune as if it were the stock sensor.
