My n\a import with auto box has a speedo converter \ delimiter fitted about a year ago and seems to work fine but my steering has gone stiffer than usaul.

I thought at first it must be the steering rack control unit next to the ecu, but have had secound thoughts that it might be the delimiter\ converter playing up.

Could it be this and the speedo reading being ok ?

If i fit a uk clock set from a tt, would it work on a n\a ? and would this mean i would no longer need the kph to mph converter ?

Would i have to change the speedo sender sensor on the gearbox ?

 

 

 

This is really doing my head in :smash: ( and my arms due to the steering bieng heavy) , so any help about this is apreciated.

More likely to be a connection to the convertor box broken. I assume your speedo still works.

yep, speedo work fine , where is the convertor box ?

do i have to remove the dial \ clocks unit etc to find the converter box ?

Wired into the back of the speedo somewhere. You'll have to remove it and follow the wires to whereever they mounted he little box - about the size of a matchbox usually.

but if i change complete dial system for a tt uk version, will it work ?

Should do. You will then need the ECU chipped to remove the speed limiter.

But if i dont , whats the big difference going to be ? Will it make much difference to my top end , not forgetting its a n\a auto ?

The JDM speed limiter is set to 112mph iirc.

"oh" That's no good

isn't this a speed sensor issue? Faulty connection or muck in the grooves of the rotating part of the sensor. Stuck for descriptive words. Dosn't the steering go heavy because the speed sensor isn't working?

 

Anyway - good luck.

Whats iirc ?

but if the speed sensor's not working does'ent this effect the speedo as well, which mine seems to be ok .

Whats iirc ?

IIRC =IF I REMEMBER CORRECTLY :)

but if the speed sensor's not working does'ent this effect the speedo as well, which mine seems to be ok .

Do i take a chance and change the speed delimiter ?

I don't think that the speed sensor affects the speedo - I seem to recall that the speedo feed is from a different source and that the speed sensor is power steering only. It's a while since I've had a auto na and I recall the steering getting heavy now and again, but I don't recall the speedo being affected in any way.

 

Someone tell me where the speed sensor is on a na. Is it on one side of the diff? or is that abs? ...comon chaps, refresh my memory (you know I'm old).

You could try bypassing the delimiter just as a test.

i.e. wiring it back as it was before.

The speed sensor signal goes first to the speedo and then on to the ECU. If the signal to the ECU is interrupted then steering will be odd and HICAS will be confused (I think) and the autobox changes may also be affected (perhaps) . The speed delimiter, or to be correct, speed converter changes the km/h signal to mph and hence fools the ECU into thinking 180mph = 180km/h (112mph).

I had a jap na recently and drove it without a converter and then with a converter - and there was no difference in the steering feel. Mind you it was a manual. I had alway thought that a speed converter lightened the steering as the ECU (that controlls the speed sensitive steering) thinks you are travelling slower that you actually are, but my experiences say otherwise.

 

Good luck

I was looking at a TT at the weekend that, for reasons known only to someone else, had the speed signal to the ECU disconnected and the steering seemed to be permanently light. This surprised me as I expected it to be heavy, but there you go. Needless to say, with the signal connected back up then everything worked normally.

That's an interesting thought - maybe it works the other way round - assistance is reduced with speed... would make sense - you need it this way around for fail-safe reasons.

 

Dosn't help the original heavy steering problem though.

Off the top of my head- and because I had the same problem until I looked it up and changed the speed sensor- if sensor U/S, speedo does not work (fairly obvious I know) and power steering cuts out after 25 seconds- Autobox goes into safe mode and will not change up beyond 2nd. (the 'Get you to garage' thinking)

 

As Andy says- speedo must be getting a signal to function, and problem further on.

So its best i disconect the speedo delimiter to see if this works , and if not :cry: .

Yeah, ditch the speedo converter and see how it goes.
