Does anyone know how to get rid of that nasty 110mph limit that the stock ECU has. Or atleast make it higher without changing the stock ECU.

 

there is no speed limiter.........

 

 

Hmm. I am not sure but when i hit 110mph the motor seems to cut out until i fall below that speed. I just got this SI so i don't know that much about it. What would you call the motor cutting out then?

op your a dumb *** and should lose your license

 

I guess you have nothing constructive to add to this thread.

 

JDM k20a and JDM CTR are limited to 180kmh or 110mph do u have one?

 

I have a stock 02 civic SI. I beleive the motor is a K20A3.

 

maybe u got a cool ep with a retarded ecu? i havent heard anyone else with this problem on their stock ep

 

maybe ur ecu is not stock? Someone did a kpro on the original ecu then swapped whatever they could get their hands on to put back in the car?

 

yah there is no speed limit, or goveneror i mean

ive hit at least 120--once hehe

 

Thanks, i had no clue about that. I guess it is possible that the previous owner changed the ECU. I am not sure if you know this one. What RPM does the IVTEC kick for the JDM CTR or JDM K20a?

6k i think and 2.2k for us which u dont feel at all cause it just becomes 16 valve after 2.2k

 

Hmm. I am pretty sure i have the JDM ECU because my ivtec kicks in around 6k -6.2k . And when it kicks in it definitely feels like i pushed a NOS button or something. The only thing that sucks about having this ECU is the governor. Any thoughts on how to get rid of it? I know reflash is one option. I was actually considering changing the entire ECU because of this governor issue.

 

k20a3 does not have the three lobe VTEC.
Since you stated in this thread that you have a STOCK 02 Si, it is highly unlikely you have anything you're describing.

The only speed governor is gearing and power.

 

Cuttting out would be you reaching 110 then the motor revving down to 105 or so then going back up to 110.. Something like GM vehicles do.

You are most likely in too high of a gear, with too little power, and wind resistence.

 

my stock 02 ep will do 140 then wind resistance kills it dont ask me how i know just know..................

Bahahahahahaha

 

Umm. I bought the car from a dealer so i assumed that the engine was stock. The Vtec definitely kicks in at around 6k-6.2k RPM it is very obvious and it definitely cuts out at around 110MPH. I just tried it again today on the way home just to make i wasn't going crazy. I have been asking around and all the symptoms point to a possible ECU swap. The motor is definitely a K20A3. However i cannot rule out the possibility that the internals might have been upgraded. The car is pretty quick.

Anyway, i kind of went off track for a second. Back to my original question. How do i get rid of the nasty 110MPH limit without changing the ECU. Or would i need to get an entirely new ECU?

 

ur on dope....

 

What's the rev limiter set at? I know the redline on the tach should be about 6800 rpm, but how high does the motor rev?

 

Idling the limiter is at 6k. Moving i have gone up to 7.5k no problem.

 

only dope's do dope uu ******* druggie moron sell ur car and buy a kia u wont have to think as much

 

Hahaha. Relax, it is not that serious. Calm down before you hurt yourself. Not everyone is as wise as you when it come to cars. If i wanted a Kia i'd probably come directly to you for advice. Thanks for your input though.
