Help with Speed Limiter / Unichip

Jeff · Post by **Jeff** » Sat Aug 02, 2003 6:51 pm

Does anyone have any information on the speed limiter for the tiptronic FTO. I am told most Jap cars have the speedlimiter built in the ECU and is very easy to over-ride. I was looking at installing a unichip for better performance and getting rid of the speed limiter. The tech I was speaking to stated that the tiptronic version also has a speed limiter in the gearbox. So a Unichip may not overcome this. Is he right? I understand that the FTO ECU is very good so I will probably not pick up much performance, so is pointless to go ahead if I cannot get rid of the limiter.
Anyone got any info on this?
Many Thanks Jeff.

I'm not sure about being pointless - Nathan Pilkington's racing FTO was using a Unichip.

I spoke to my mechanic about this and he reckons they can put a piggy back thingy in for about $800, this will overide the governor and let you reset the revlimiter to whatever you want. (heard some have been running non mivec 6a12 to 10000rpm)
With this option, at full noise, 5th gear, I worked out a theoretical top speed of 280Kph.

This might be different with auto. Without the rev change, think she will go to 240. Of course friction and drag will be the final deciding factor.

In the UK they do a 180MPH speedo which is 280kmh. They fit a piggy back thing which changes the speedo to MPH and delimits it. Dunno about the revs. This is probably the way I will go, with dual speed RED dials.

Thanks Elmo,
Is he just talking about the rev limiter or a separate speed limiter on the gearbox?
Have you got the contact details for your mechanic, and the device he is talking about? I know the apexi speed meter will piggyback the ecu and override the speed limiter on the ecu, and possibly the rev limiter as well.
Thanks
Jeff

If you have a MIVEC engine you can get a MIVEC controller that will de-restrict your engine.

I know there is a site in Japan that sells them. I could find the URL if anyone is interested.

The car gets its speed from the gearbox speed sensor, which used to be mechanical on the older cars. It is just an electonic pulse. The thing my mechanic was talking about just changes the pulse to confuse the computer.
The MPH converters can be doctorerd to do the same thing with just a couple of wires extra.

As for the MIVEC/V-tec controllers, well they will do it but they are an expensive option, will probably pay that much for the controller then the same again for the harness, more to set it up properly and still no real advantage, (unless you plan to turbo or go with serious mods)

i have seen how tos diy on the internet somehwere ill find it and post a link later, wasnt game enough to try it my self, but wouldnt mind going past 180 some times

Think there is a link and a thread on the WA board. http://www.ftowa.com.au

But you need the MPH converter to be able to do it.

Elmo,
I went through the WA site and could`nt find the link.
What was it under? Where to look?

Wanna go 120mph and delimit your car for free?

Hope that works.
There is a link in that posting to another site that explains it.

What they are doing there is sending the MPH signal to the ECU instead of the KPH signal. So, the car is still limited to 180 - except its 180 MPH instead of 180 KPH (ok, not such a problem). But it won't work unless you have a KPH to MPH converter (which most of us wouldn't).

Thanks guys but we are getting a little off topic. The unichip/apex speed meter/ (mp/h/km/h) are all ways to delimit the manual FTO and I thought tiptronic. My question was, Is there a limiter on the tiptronic gearbox as well? Talking to a techie, he told me he couldn`t delimit a tiptronic FTO because of a secondary limiter on the box itself. I hadn`t heard of this before so I wanted to check this out before I forked out for a unichip.
Has anyone else heard this?
Many thanks
Jeff

hey jeff, did you have problems derestricting your speed with the unichip?

i have an APEXi RSM in my car and there is only one wire that need's to be "fiddled" with to override the speed limiter and it connects directly to the ECU (not the tip ECU).

i haven't taken to the car up beyond 180 but i'm sure it works

i'll put it on the dyno if i have time and test it out

yeah you should get higher readings from 3rd gear anyway

i assume youve been doing them in 2nd upto now...

going to double check it when i get a chance to go to unique and throw it on the dyno

interesting point that, up until yesterday I didn't believe it, as the engine puts out the same HP regardless of what gear you are in, but as I discovered yesterday, dyno's don't measure HP instead they calculate it and as such doing a dyno run in a higher or lower gear will yield a different result as the ratios used in the calculation have changed.

Post by **smorison** » Tue Apr 20, 2004 11:55 pm

i know in the past my car has been dyno'd in different gears either 2nd or 3rd just depended on which mechanic at UAS i had on that day.

anyway this topic should probably get back on track before i have to turn into the forum NAZI and punish myself as well as others for hijacking it

Thanks for the inquiry.
I`ve had the unichip fitted, and the tech wasn`t sure if it fixed the limiter or not. Since then I`ve had it up to 175, but no higher, run out of back straight at Willowbank. So I don`t know if it has defeted the limiter.

the MIVEC controller; can you set that to by pass the speed restrictor? how easy is it to do? and whats the going rate for a decent mivec controller?
