Does the ECM control off of IAT2 or MAT? I remember reading that it controls off of MAT.

I also need to do some logs on my car because it definitely gets slower during sessions above 80 degrees. Good thing it's supposed to be 94 at Pitt Race Wednesday for TNiA!

UPDATE

So my mechanic pressure tested the intercooler system and could not find any leaks of any kind, however they said that the system was low on coolant... Obviously i’d like to know how the system got low on coolant and I can’t imagine it wasn’t the leak that I saw That now seemingly cannot be reproduced. The only thing I can think of now is to drive the car like I normally do and monitor and observe it and see if it reoccurs

Thanks for the update! Usually, leaks dont just disappear, unless there was an extraordinary pressure event of sorts perhaps. Good idea to check motor compartment and under the car for any leaks after each and evey session regardless of prior leaks or not. Just a good protocol for us track rats. You should know in short order if that leak comes back or not. Cheers!

I sure hope I know soon! This seems weird...

The good news is that the cars seems to have full power back from what I can tell, I drove the car for more than an hour and floored it a few times, so if my senses are correct, the power is back at least for now.

Fingers crossed! Time for a new PB

Yeah by more than 2 seconds from last track day!

All controls off and left foot braking along with SC3R’s have cut more than 2.5 seconds off my best lap time from last year.

No Intercooler leaks at the track... the mystery continues...

I've had an internal intercooler leak - into the intake tract. There are 4 o-rings that seal the cooling fluid from the pressurized intake. A possibility...

Dont forget to give the driver some credit as well, eh?
Congrats!

I'd also check the o rings per the post above. Just to eliminate it as a possible cause.

Thanks, I'll tell my mechanic about this and see if he has already checked this
