Hi guys,
My A90 supra is totally stock, and I have been surprised that few people seem to have mentioned any kind of power limiting on their car especially for those who have upgraded turbos, downpipes, tunes and so forth.
I came across this issue first on the circuit, after 2 laps, it seemed the car went into a limited power almost limp mode at high speed, basically on the straights at top of 4th.
Essentially it felt like I was only pressing 50% throttle which was frustrating as it was happening just before crossing the start/finish line and killing my lap times.
There are no warnings, no CEL, nothing obvious that would suggest there was a problem.
If I bring up the "sports displays" I noticed the power was maxing out at around 145kw instead of the usual 245kw on the screen.
If I backed off for 10 seconds the car went back to normal, which made me think maybe it was intake temp related.
Ideally I would have liked to be logging oil and intake temps via obd but I was already busy with getting myself sorted for the track sessions that I didn't have time to do debugging.
I later turned the air con off and for the rest of the day, I didn't experience a power limit.
Now here's were it's strange, last night in cool night air, on the highway I experienced the same issue for the first time *on the street*, after overtaking a few cars to get into the off ramp.. same symptoms, limited power, no warning, but power displays only going up half way.
Being that it was a chilly night I didn't expect anything of the sort.
I know another Australian supra had the same issue at roll racing, but I am wondering if anyone else has narrowed down the issue and has an answer/solution?
I mean Australia is typically warmer than rest of world, but it seems pretty stupid I get no warning or CEL to indicate there's an issue..
Any help or experience welcomed
