https://phys.org/news/2018-12-nissan-scandal-ghosn.htmlMost cars shut off the A/C at WOT to prevent damage. Surely with all the electrical crap on the VR30ddtt they employ this.
You're missing the BEST part about the car.......Believe or not I have actually never went WOT on this car. I just don't really drive that way lol
Will have to check it out. Was in manual mode at the drag strip last week and heard no chirp, but no A/C obviously.I guess I just don't drive anywhere that it would be safe to do that.
Keep an eye on that chirp, mine would go away and come back. Try going in manual mode, 4th gear, AC on and cranked, and give it a long 25% throttle pull and see if it starts slipping at 2800-3500 RPM, thats when mine was the worst. Sometimes it would just do it through 3 and 4 gear, and I don't know if it was related to ambient temps or what.
Can you explain the last sentence? The AFR is richer at WOT than at part throttle/idle.Excellent write up of your entire process @helterstupid, I think we need to get the mods to add a sticky to this thread.
Works as a great "How To Guide" if you are looking at perusing a lemon law claim against a manufacture.
On a side note most mechanics actually recommend owners take a modern turbo DI engines near red-line AKA "The Italian Tuneup".
It allows the engine to reach higher operating temperatures where it's harder for Carbon to form and it has a greater
chance of loosing some of that build up so it can be shot out the exhaust.
The fuel/air mixture is less rich so your having a more complete fuel burn as well.
Aye that stuff is excellent, I tossed a bottle into my Altima at least once a year to clean out the injectors.That stuff is like gold. I've used it for years.
