Speed limiter on 2012 Civic Si?

[Anonymous]

I haven't been able to find any information on this by Googling, etc. but one of the things that the Hondata reflash says it addresses is "speed limiter removed." That's a different item than the "rev limiter raised to 7600 rpm" bullet.

Does anyone have any information about this? (First hand or otherwise? ;-) Does the Si ship with a top speed that's limited by the ECU?

That's a very good question!

SI is limited to 145 I believe from the factory thru the ECU

There is a speed limit encoded into your ECU. Hondata has the capability to remove it. That's all I know.

as jasonandre said, hondata can remove that. Saying that, there is also a limit to redlining 6th gear, and fighting wind resistance.

Mine also revved out around 136-138, I forget the exact number.

Brave man!

I am going to top it out on my way home from work tonight on the parkway, there's a good flat section with no turns. I will reconfirm.

I never understand why they do that. It should be based on your driving habits when your driving a tractor trailer, not a regular car. But that's just my two cents about it.

Thanks for the great responses, everyone. I've been wondering ever since I saw that on the Hondata site.

My buddy picked up a 2013 Mustang GT a few weeks ago and had it doing 145 mph at about 3000 rpm over the weekend.

I guess baby needs a Full-Race turbo kit...

3k RPM at 145 is lolz. go 5.0!
correct me if i'm wrong, but isnt the 5.0 also around a 5.5k redline?
if so, that would basically be like us hitting 145 at 5k rpms roughly in my off the cuff ratio math

 

[spdandpwr]

^5.0 redlines at 7k, stock. But, that guy (anonymous) might not have the shorter gears on his car.

 

[mongoose221]

ahhhh nice. i didnt realize they went so high! that's a SCREAMER for an engine that size

 

[spdandpwr]

the 6.2 liter v8 in the mercedes amg vehicles redlines at 7200 rpm, lol

 

[mongoose221]

i take that back... it's a screamer for an american v8 : )
i know those crafty krauts have some beast machines

 

[spdandpwr]

well, actually...lol, jk...go american engineering!

I can confirm I hit 136 mph on all season tires last night on a long flat straight stretch of road. 137 might be what was done on summer tires.

136 mph is pretty da*n cool to me! Thanks for sharing!

Also, thanks to everyone else for helping me out with the Mustang specs. I didn't get a chance to talk to my buddy today.
