Torgue App Cat Temperature - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Can anyone confirm the temperature for Cat B 1 S1 (using Torque), after warmed up street use?

cdrazic93 · 02-09-2015, 10:42 PM

Usually cats like blankets and warm laps.

I havent checked the full functions of Torque yet, but why would you need to know the temperature during normal load?

I have a new 2.5" cat back and am interested on the affect of EGT, since we don't have any way to measure the EGT, closest is the cat temp.

Cat temp is very very different than EGT. Running rich can lower EGT's but drastically raise temps in the cat.

It would be good to get consensus on the normal temperature range.

I have read that the cat temperature should be between 560C/1040F ~ 650C/1202F , street use.

Can anyone confirm this on Torque? Does EcuTek OFT show the cat temps?

Bump, can anyone please confirm the temps they are seeing... thanks

Why would the ECU have any of this information for any tool to tell you? There is no cat temp sensor. All that the ECU cares about regarding the cat is the second oxygen sensor to make sure it is working.

The ECU calculates the cat temp and provides this info as a PID.

You can get the value using Torgue and ELM Bluetooth adaptor.

I would like to know what the temperatures are with a stock exhaust.

If the ECU is calculating temp it's going to be off by your exhaust change. If you want to know EGT then install a sensor, what you're trying to do here will not give you accurate(or useful) results.

I've been running about 800-1100F on mostly highway and suburban streets. (35-70MPH cruising, very little stop and go, but a good deal of traffic.) Air temps have been 20s-40s, and I'm measuring oil and coolant temps in the 180-200 range once warmed up. The engine, intake, exhaust and tune are all stock. Fuel is 93 AKI.

Here's a chart of my most recent log:

Thanks for the detailed post.
