Basically there are two feeds one what goes to the steering, and one what goes to the odomiter, if you alter the speed at the gearbox, the speedo will read correctly however the steering will think your oing 70kmph when your really doing 70mph. This will cause it to give you the wrong amout of feedback (you have noticed that the steering wheel is very light at low speeds and firms up as you push on havent you?) so there is another converter on that leg to adjust it back to Kph so that the feedback you feel is right.

Hope that explains why there is two conversions.

 

So you have an mph to kph converter for the steering?

I have two kph to mph converters. There are three things to consider: the speedo, the power steering, and the ECU (which does the limiter). Mine has two converters: one before the ECU (in the passenger footwell), and another behind the dash for the speedo (I assume - never seen it), and the power steering gets the correct uninterrupted signal.

Gritty's single gearbox converter is the easy way, but it means the power steering gets the wrong input (not sure how much difference that really makes), and as he's found it's more exposed to the elements.

None of these things derestrict. What they do is change the signal from kph to mph, so that the limiter now cuts in at 180mph instead of 180kph. I don't find a 180mph limit much of a problem.

 

Ah yes that makes sense Dembo, I guess theres a few ways of achiveing the same thing?

 

no problems with my steering with only 1 converter (that i have seen)

 

so you need another converter for the powersteering??? damn this is all confusing!!!
Ok, so back to my original question, does anyone have pictures of the soldering you have to do behind the dash so you can just press the select button? and will that cure the steering problem?

 

I have. Mine is the only S I have ever driven, so whether I have an extra sensor or not I don't know. The steering feels perfectly fine, but I have no basis for comparison.

 

yea but shouldnt a signal just be a signal?

 

TBH we dont know how many gradiants there are, or how much the steering adjusts to the speed, it may well be Negligible after say 30-40mph. be interesting to see if you notice a difference in another car though.

 

someone at a Honda dealer would know best i guess. might go to Alan Day tommorow and ask them. So does no-one have any idea about the soldering of wires inside the cluster then? ooh, and 1 more thing...these converters, theres so many different types on the market with a massive price difference, and there are these "speed defenders" which de-restrict. wats the difference with them all, are some better than others with different functions or am i just paying for the name HKS etc?

 

I wouldn't hold your breath for that one.
