Is it True about fuel cutoff
On the Acura site it says that the 2001 CL and Type S has a fuel cutoff at6600 and 7000 RPM. But the 2002 TL and Type S doesn't say that it has one. Does the TL have one or just the CL.

Since the engines in the TL-S and CL-S are identical, I'm sure the fuel cutoff is the same and it's 7300rpm for both!</STRONG>

Here is the excpert from the Helms:
Fuel Cut-off Control
During deceleration with the throttle valve closed, current to the injectors is cut off to improve fuel economy at speeds over 1,100 rpm.
Fuel cut-off action also occurs when engine speed exceeds 6,600 rpm, regardless of the position of the throttle valve, to protect the engine from over-revving.
When the vehicle is stopped, the PCM cuts the fuel at engine speeds over 5,000 rpm.
Comments:
I do know for a fact, that the car has a lower fuel cuttom when "stopped" (in neutral/park).
I think they made a mistake in the Helms about the 6600 rpm, or forgot to mention that this was for the CL (I'm just guessing, since they don't mention the 7300-7400 rpm fuel cutoff in the same paragraph for the CLS).
If you want to look yourself, the page is 11-27 in the Helms CL/CLS manual
I would tend to believe that the fuel is cut-off during deceleration, as this is a common tactic to reduce polution and fuel consumption.
