lets get some things sorted,4 all those people that havent got a clue ,dont bother answering back!,2 the car is an import,2.2 si,vtec,4ws and is used as a track car!.so get of your high horse!

p.s phish whoever u maybe,the thing thats old and knackered round here isYOU!

Answer 1

To all the people complaining about the speed: SHUT UP! Did steph ever say this was to be used in downtown traffic? Ever heard of a 1/8 mile and 1/4 mile dragstrips? Educate yourselves before opening your pie holes!

Anyway, you need to remap the ecu computer chip. The engine management is always conservative on a Honda that's why they last forever.

Invest in a heavier clutch, I had a 92 lude' and once the horsepower got above 250, I kept burning up clutches after hard launches.

Enjoy the performance of your car and ignore ignorant people.

Answer 2

I doubt if it has a limiter on it.

Are you 'hitting' the limiter - ie. you can repeatedly get to 120 an it just goes no furthar.

Speed limiters are usually only fitted to newer cars.

If it is limited in some way - getting an engine ECU remap, or replacing the 'chip' to delimit it will have the desired effect.

£30 on ebay for a DIY "super chip" or £500 for a pro remap.

ps. Speed does NOT kill. Not being able to drive does....so does showing off to your mates, impairing your skills through drink & drugs, having an unsafe vehicle or misjudging conditions etc. If speed alone killed...then why isn't there more deaths on the road?
I hate the anti-speed brigade with a vengence, bunch of overly PC, tree hugging, pseudo environmentalist that believe media and government hype. Just utterly, utterly pathetic. Get sone FACTS before spouting off. The KSI data used for the 'speed kills' campaignes was obtained in part during the 1970's.
Hang on, hasn't car safety design, 'pedestrian proofing', and other advances been made in the last 30 years? Uh, huh. And was that 'data' obtained scientifically - NO. The impact speeds were based on driver & police ESTIMATES. Now go away an get something better than just repeating what you've heard....look for the proof!

Answer 3

I am assuming that the car is a Jap import. If so, the best way to have the limit removed is by having the injection system re mapped. I know that some of the Hondas had a system on the speedo head but i am almost certain that re mapping the injection system will solve this. I had an integra type r which also had to be re mapped. No more limiter. Crazy car.

Answer 4

Here's the thing - more often than not, the speed limiter is calibrated to the tires' speed rating by the vehicle manufacturer. You will need to reprogram the processor in order to remove this function - and that involves a hand held programmer of sorts, usually in the $300-$400 range.

Answer 5

Question - What RPM is your engine at when doing this speed? Perhaps the gearing is pitched a little short, to ensure the car gets up there quickly, but it might not be able to go any faster, if your revs are at the red zone on the tachometer. Is it a VTEC engine? If so, I'd ask if the VTEC system is engaging properly.

Answer 6

If your car is an import, it is limited to 112mph (180kph). Go on eBay they do little de-limiters for imports for about £30. This changes your speedo reading to MPH so you might need a new face (www.importsolutions.co.uk). They are easy to fit but require some wiring, an auto electrician would be a good idea.
UK cars should not be limited, however if it is then the ECU will require a re-chip.

Answer 7

Is this car in Japan? You could check. I dont know bout the hondas, but on the Nissan (Silvia's) there was a 2 wire sensor on the transmition near the rear. On the Nissan cutting this (open) made the computer think your are not moving. Thus the computer would not cut the power to the fuel pump ever.

Answer 8

i too am addicted to speed so i wont have a go! to cure this all you need is a superchip which goes in the ecu which ultimately changes the way the ecu thinks and will get rid of that nasty limiter those preludes are good for 150mph just so you know

Answer 9

Use a Spoon chip for the ECU, it removes the speed limiter. Or you could get an Apexi or Pivot speed meter which interupt the VSS signal.

Answer 10

What makes you think a 'limiter' is fitted?
Limiters are fitted to diesel engines to stop them over revving.
The only possibility of getting higher speed out of it is to alter the engine managment chip if one is fitted
