I’m an idiot — first launch, forgot I was in manual mode and crashed the rev limiter

[Nsxrook]

For all your techs out there, should I at all concerned? Will the car log this event?

If you hit the rev limiter, it should not be a problem- that's why they put the limiter there. I'm sure a NC1 owner can chime in, though it may not be well-known what the NC1 ECU considers bad and logs. My GT-R logged the number of launches.

I wouldn't worry about it. I missed a gear while driving my 997TT 6pd many years ago and hit the rev limiter and grinded my gears. It sounded awful and I thought my car was done. I was worried sick for days afterwards but car ran just fine with no issues for years

The rev limiter is there for a reason. Don't worry. Go have fun with your NC1!

No problem, as stated the rev limiter typically cuts off the fuel which limits the ability of the engine from exceeding the limit. I can recall once driving my 2001 NSX-T which was supercharged into the rev limiter. It was shocking but not an issue. They designed the system to keep the engine safe. Where you can screw things up and potentially damage the engine is when you downshift from 5th and accidentally go into say second. Depending on how fast you were going you could force the engine to exceed the rpm redline. Porsche measures this and stores how many times you exceeded the redline and by how much. With PDK or our 8 speed trans I believe you cannot force the engine past redline. That is why Porsche does not store data for the PDK transmission cars.

One of the Acura development Engineer did say that all LC's are logged within the car's ECU, and that after X number of LC's the transmission will need to be rebuild.

I thought that too based on an Acura Rep driving with Jay Leno in a NC1. The Acura Rep said after 400 launches the transmission should be rebuilt. However, when I had a PPI done on a car I was interested in, the Acura specialist said they could not give me a count of launches. I am not sure if he was protecting the seller because he was the servicing dealer or whether launches are really not counted.

I spoke with one of the engineers on my NSX drive session at the Transportation Research Center three years ago. They indicated that they have development NC1s with thousands of launches on them with no trouble. He further explained why that was. Launch control uses the batteries for initial torque and launch, for just long enough for the transmission to “slip gently” into place, thereby preserving the transmission. He said nothing about a transmission rebuild after a certain number of launches. Has that info changed?

Straight from the NSX FAQ on Acura Info Center

"How will using Launch Mode affect the lifespan of my NSX?
Because the NSX’s three electric motors get the car moving before the clutch is fully engaged, launch mode in the NSX is less abusive to the powertrain than launch mode in conventional, non-hybrid supercars."

Another reason to love my car!

Thanks for the confirmation! It’s a cool, nerdy feature I always enjoy sharing with others when discussing the NSX.

I'm thinking the only way the average owner would ever apply launch control 400 times would be the "guy" with the youtube channel with the scantily clothed giggly passenger....
