Defeat The ST Limiter???

[Motors]

Has anyone found a way to defeat the factory 120 mph limiter on the ST1300PA???

Please advise,

Thanks,

Motors

I don't know if this will work, but I wonder if you could do it by installing a SpeedoHealer. It plugs in directly to the VSS. Correcting your speedo should allow another 7% (~8 mph) top speed, assuming the speedo is off on your bike the same amount as on a civilian model.

You could also possibly program in a false speed correction, say 10 or 15% to keep the speed signal lower than actual. Maybe the ECM will believe that number and allow the speed to increase

Just blowin' hot air, but it seems to me that if the po-leece made Honda put the speed limiter on then someone else could take it off - 'specially since the patron/subject [i.e., stock] ST bikes don't have it.

Typically ECUs cannot be reprogrammed after they leave the factory, so I doubt very seriously if the ST's can. The best option may be to swap ECUs with the regular model. Costly option $$$$$

I suppose you could swap ECUs with someone who has a regular ST and doesn't ever intend to go that fast. :D

Looks like Blrfl just volunteered!

That's really scary. I was thinking about adding "I'm not volunteering" to the end of my post.

Well you do live in the land of 1000 dollar fines... I thought you were acknowledging that you really wouldn't even *dream* of going past the P model limiter...;)

My limiter seems to be broken. :)

Who said that?

I have been asking the same question for my ST1300P. I found out that Dynojet used to make a programmer for the bike but they stopped making it in 2004 because some would work but some would not. A dealership in Houston could only find 1 place that had two left in storage but there was no warranty or guarantee that it would work. I spoke to some mechanics including Honda's techs and they said that the only thing they could think of is to replace the computer. Honda dealership in Beaumont said it would cost a little over $700 to replace. :shock: I am not sure if the end result will be worth the cost.

I think I'd rely on the old saying in this case... "You can't out run radio"...

Thanks for the comments. It just seems to me that the STP should not be pennalized for being a police motor with a slower top end, when the civilian version can do 140 mph. I understand the limit on the STP due to the high speed wobble experienced on some police motors in Europe and elsewhere. Obviously Honda is admitting there is a problem and they don't want to see any suits via American lawyers, so therefore the limiter. So why not limit the civilian motors?
Let's hope Honda is working on the problem.

If I were a betting man I would say that the police model is dead on with the speedometer..if it says 120 you are doing 120...equate that to a regular ST speedometer and he has to be showing about 129 on the board to do an accurate 120. I believe your speedometer is in different increments on the dial and is certified by Honda from the factory.:)

[tnman]

The ST-P is pretty much 100% on with the speedo. I have radar and GPS on the bike and all 3 agree pretty much perfectly.

I have 25 Honda ST's in my fleet and when Honda was giving the 1300 to PD's to test the demo units didn't have a speed limiter. Most of the commments by departments when the bike was tested said was it is to fast. So Honda added the limiter to slow them to 120 mph (BMW's are limited to 115)and the Kawasaki's had limiters in the carbs. I tested the demo unit myself and had it over 135. If you defeat the limiter and have a high speed crash what would your department say, I know poop would hit the fan at my place....

120 limit on a motor? How fast can a Crown Vic go?

[ccryder]

Motors:

The ECM are easy enough to switch out. If you were in my neck of the woods we could run a trial to see if that resolved your limitation.

You may want to PM Turbocity Tom and see if he may have a solution.

Crown Vic can go 129. Impala 140. Smooth top that is.http://www.michigan.gov/documents/msp/Acceleration-MSP_VehicleEval08_Web_221472_7.pdf
LAPD almost crashed a 1300 in a high speed test - luckily the motor officer recovered. It is the opinion of some agencies that Honda couldn't solve the gremlin in the front wheel problem so they installed the limiter and then called the 1300 an urban patrol vehicle only.

[DeSTy]

Wow, a gremlin in the front wheel now?, is that the cause of stability issues?

[curmudgeon]

I think Honda is being unbelievably stupid here. Why don't they just figure out a way to add the CBR's electronic steering damper to the ST1300? Couldn't be that difficult.

So, the P model can only do 120.................. :turtle :nanner1: :crackup

Would certainly think so. I know I've had mine up to 145 before so doesn't seem fair that the PD model be restricted.

May not be the steering dampner though. I noticed a similar issue when I installed my GIVI 52 Top Box. Damn thing caught enough air when going over 80 mph to lighten the front tire to the point that I got a similar wobble. The solution is simple though. Stiffen the dial on the suspension and the problem goes away. May not solve there issue but certainly wouldn't hurt. IMHO

[Jefro]

I asked Huntington Beach Honda about the limiter, as they are the west coast distributor of the P bikes.
They said they are asked all the time to disable the limiter, but they will NOT do anything to incur liability.
However, the ECM is the unit that controls this. The swap for a civilian unit is expensive but simple.
There are many here that have had their civilian models up to 149mph, GPS verified, (including Sgt Byron, but you didn't hear it from me).
