DOes anyone around here know how to nix the stupid nanny? European Legends do not a have a governor, giving the car a totally credible 155 mph top speed. I also suspect, that although governed at 134, the nanny blunts performance significantly below that limit speed, the RL would probably still be pulling strongly at that speed. Another bonus is that without it the RL could safely outperform the cop dodge charger chase vehicles (if so required ).

 

What speed rating are our tires? Typically the speed limiters are put in place to comply with tire limits.

 

The CMBS tires are rated for about 140. I forget the exact number.

 

The stock Michies are V-rated (149 mph).

 

There have been tons of posts on the CL board about the same topic and nobody has ever had an answer so it's probably the same story here unless you can import all the parts from a non-N. America 'RL' but sounds too expensive for the value.

 

All three types of the stock tires, Pilot MXM4, are rated V=149mph

245/50-17 98V
245/45-18 96V
245-680R480A 102V

Yes, I was aware of the tires V rating.
Eliminating the nanny should not cost anything at all. It is simply one of the engine management modifiable parameters. Thus any dealer should be able to do it (but won't due to legal issues). All JDM vehicles are limited to 119 by law, however, euro spec vehicles are not. Its all a matter of hooking up the car to a PC with the engine management software and using the correct code.

 

Given the frontal area and cd, as stated, I wonder if the RL can get close to the 155 MPH stated above. At least, (and this is a big one) in any reasonable distance available on most roads.

Have you seen any tests that show the RL at 155?

 

The 155 is the top speed stated in the German and British honda websites for the legend (honda.uk and .de). As far as Cd, the RL, surprisingly, has one of the smallest Cd's in the industry. It took me a while to find the number but its in one of the prerelease Honda news articles. The softening of engine performance after 110 is the reason I believe that the limiter is starving the engine right around there if not it would be imposible for it to reach 155. I have driven it to 134 (US limit) it feels like a rock at that speed. There is not abrupt cutoff, it simply will not go any faster.
At present, Im Emailing JET industries which claim they have a reflash for the the RL. I don't want them to screw with all the parameters, just remove the top speed limiter. I'll let you know what they say. Judging from the TL's strong pull up to about 130 (the TL has no limiter) I bet you the RL will perform similarly.
Another good point to make about the RL's straight line performance. Slight torque braking will easily shave .5 seconds to 60 (6.5) and will drop the 1/4 mile to 14.9 and 94mph respectively. The RL's ECU is definitely calibrated more for fuel efficiency than performance. A complete reflash should easily unlock up to 25 additional ponies.

 

I Have An 02 Tl-p and i dont believe our cars have a top speed limiter i think just a rev limiter. I know this because I've taken my car to 144 mph and the only reason i stoped cause 1. I smoked the tiburon i was racing and 2 i didnt want my tires to blow. but ya thats my experience.

 

The TL does not have a limiter. The RL does.

 

I thought the 2nd gen TLs had a limiter.

 

Nope it will go all the way to 150 plus. However, I dont know about the Type S.
One point of caution the standard turanzas on the RL have to be pumped up to the high speed pressure indicated in the manual, driving them at normal pressure at that speed is extremely dangerous.

 

Mine is disabled via my apexi rsm... too bad I don't have a road to test it here in the city.

 

VAS IST DAS?

 

Bad news, JET does not offer anything for the RL.

 

I was on the way home and my buddy followed me with his 07 350Z, then I pushed my RL all the way and it just top to 115 mph he followed and of course he passed me easily. I was surprised because my car only can go 115 and wont go any faster. I know this car is not for race but my previous TL can go up to 150 mph easy. I missed my TL so BAD! So any mod that I can do to make this RL more aggresive?

 

Something is wrong with your puppy. However, like many cars the RL only reaches top speed in 4th not 5th.
