does weather affect a/f ratio w/ translator

Last time out racing it was 85 degrees were going saturday and its supposed to be 55. do i leave my settings alone or since the air will be more dense do i richen it up. Trans plus w/ extender chip

You should still be pretty close. The ecu combines information from the IAT and the MAF to calculate airflow. So in theory, it corrects for changes in density due to temperature all on it's own. There will be some differences, but they should be slight.

With the extended Maf range with the extender chip it should adjust to temperature and air pressure changes better than a chip that is estimating fuel above a 255 maf value.
