That cold mode does a lot of weird things to the motor. I made a video a while back about how my boost behaves differently when the engine is cold.

It's blue on my Canadian Echo, takes a minute or two to turn off in the summer time. Never saw it turn red, even at lower speed road courses.

Just picked up extra coolant on Friday night (some is always lost when changing a T Stat) and then was busy with other crap all weekend. I'm booked the next few nights after work, so the first free opportunity is probably Friday night (to swap back to stock T Stat and then after that maybe also try the stock TB) W |

At 175, I can't imagine it's in cold start mode. Is the OP losing power at that full temp reading?

175 is over the cold start mode, but he said cruising that he was seeing 140 to 175. If in motion it stays down to the 140 mode, it will run more like the cold mode.

It's ok. We'll wait. We gave Astroman over eight months. You're good.

here is my datalogging?
outside air temperature was freakishly cold outside for this time of year (15deg c / 59deg F) (during this trip the coolant temp never went above 63, but like I said it was freakishly cold for an Ottawa Summer day) Driving water temp ( 61 deg c / 142 deg F) (85km/h - 53mph) (flat land / zero wind) Intake air temp(while moving) ( 21 deg c / 69 deg F) Intake air temp (stopped in traffic) (26 deg c / 79 deg F) Driving pic (it was freakishly cold out) ![]() In Light traffic (stopped for 1 minute, every 2 or 3 minutes)

I think my "cold" coolant light goes off at 135°F so you aren't running much warmer than that.
I always thought that a performance T-stat was hotter (not colder). I know back in my dodge truck days, guys would put a 195°F T-stat in place of the 180. I honestly don't think it does much. |

^ Maybe, but if he eliminates that as a cause by swapping back to stock, we can move on to the next possibility. Or, that IS the problem.

I would say that IS likely the problem. 142 F is still well within the pre-warmed-up temperature range.
It was 55F here this morning when I drove my kids less than 2 miles to the camp bus and by the end of mile 1 (mostly downhill) I was at 181F.

Next step = remove the colder thermostat - take some driving impressions and datalog the info.
It won't be 8 months (or never) ala "something big is coming", but it will have to wait till Friday night or the weekend because I'm busy tonight and tomorrow night. Then, after the thermostat, if there isn't an improvement - the next thing will be to remove the Corolla TB (swap back to Stock tb on the Tooter) / then I guess the next thing after that will be the Factory Manifold etc...etc...... Only good thing about this process is that now I've done each part so recently that they stick in memory and therefore are pretty quick and easy to swap. |

That's the prime directive for modern vehicle engines. Super quick warm up to operating temperature so as to meet government mandated emissions requirements. In warm California, my green light goes out before I get to the end of the driveway.

Sorry, I meant that increasing the temp probably doesn't help power. I actually agree that his car may be in a limp mode state given that he is probably running open loop and thus on a predetermined fuel map (really rich).
I am curious to see if changing the T-stat back fixes it. |
