s300 tunning, I've got an issue

i think you need a more efficient FMIC if your IAT's are seeing 130. Unless you are just high boosting that turbo and its blowing hot air.

the FMIC is fine.


I think that because the IAT sensor is mounted on the IM, which gets kinda hot, the sensor may read temperatures that are higher than what those are in the reality.

also, one guy over H-T suggested that the stock IAT sensor is not so sensitive and needs some time to adjust its output, and therefore it may not be good for tunning. He said he use a GM IAT sensor .. but I've never heard anybody else to use that, so I don't know.

also, the turbo inlet filter sits just under the hood where it gets kinda hot, so if I move the filter elsewhere, my IATs would drop most likely.

the 15G is a small turbo though
