Fast acting intake air temp
Is it okay to use a fast acting intake air temperature sensor in the OEM location on an OEM car? My check engine light code indicates the IAT and I purchased a fast acting one from the forums.

Yes |
Yes, that's where my fast IAT sensor is.

You should also purchase the adapter wire connector if you haven't already. Makes it plug and play.

On the stock ECU? I would NOT do that. The stock tune has the slow response of the stock sensor baked into it. I wouldn't put a different sensor in there man, you don't know what the heck it's going to do. On a Power FC or other ECU it's different.

Assuming he’s getting the Triumph “fast reacting IAT” that’s been published around here, it’s perfectly fine in the stock spot on the stock tune. Ran it on both my FD’s and even in the Phoenix heat at the track. 100% fine. Matt |

On a separate but related note...why not take the opportunity to relocate it out from under the UIM to avoid a little heat soak? With a little effort the connector can be reached and removed and just leave the old failed sensor in place. Use the plug n play harness and it’s completely reversible if ever desired and you don’t have the hassle (and some risk) of pulling the UIM off. |

In case you’re unfamiliar with the triumph sensor, it shares the same resistance values as the stock IAT. Just reacts faster. I didn’t log AFRs or anything. But being able to beat the snot out of it at the track and it not break should be proof enough :) Matt |
I wish I still had the laptop with the logs on it (it's been a while), but I can tell you I had a noticeable difference in AFR's on my Power FC when I switched sensors. With the dampening effect of the stock sensor gone, the hot starts and air temp compensation table needed to be retuned. That being said, the stock ECU may be more robust than a PFC that barely runs closed loop well. We just don't know. The air temperature compensation could be off, and Power could be down or, exhaust temperatures could be up, it's hard to say without any data. Any kind of time constant or delay timer or transient air temp compensation table in the ECU is going to be off with the new sensor.
I would say change the stock sensor without retuning at your own risk, whether it's stock ECU or some other ECU (Power FC). |
All - thank you for your advice thus far; this is what I have.
