Title: exhausting tuning
Post by: ktm733 on December 17, 2014, 09:46:17 AM
Can some point me in the right direction of what to tune for exhaust or faqs about exhaust tuning? There's a back pressure change which increases engine scavaging. Which in turns bring more fresh air in, which in turn you need more fuel brought in also to get requested air fuel ratio. Ive searched and there is nothing about exhaust tuning. Wouldn't less more fresh air mean more efficiency?

The amount of mass moved through the motor doesnt change the efficiency, increasing the rpm sure sucks more mass but not more efficient. Only increasing the temperature of the motor does or decreasing the intake temp. Thermo stuff. Its such a small modification i doubt it opens much up however thats what your maf sensor is for. Your car will automatically adjust fuel if more air flows in up until a point. Exhaust alone is not close to this point i think.

I am by no means an expert with this stuff. Grain of salt

There is nothing to change except perhaps LDRPID, which should, in theory, require less DC for a given manifold pressure.
