This is my next winter project. I thought I've done them all (A/C, BOSE, SRS, ECU, TCS) so this is my next and hopefully last one.

Hi Kaz,
Thanks for tip on checking the speedo accuracy. I will do that next time when I get on the freeway.
My brakelight on the cluster was lighting up occasionally before so I will see if it happen as you mention that is a serious fire problem which shall be a big caution for everyone. Thanks for sharing!
Hi Kaz,
there are two VR1 and VR2 potentiometers- trimer on a single printed circuit board.
You can explain to me what it affects VR1 and what VR2

Hi,
I have asked for an explanation to Mr. Toyoizumi from T3Tec.
I received a reply in Japanese or there is someone who could help me translate (Google translator is not precise)
Mario says: おはようございます
私はGoogleの翻訳者を使っていますが、あなたが理解しているかどうかわかりません
英語で書けますか。
ヨーロッパでは、PCB speedo用のVR1およびVR2ポテンショメータが何のためにあるのか私には説明できません
敬意の言葉
Mr.Toyoizumi says:
私 英語分かりません。
SpeedMeterの基板?
VR1 VR2は
速度の補正
不具合が起きているのでしょうか?
Mario says:
Acura NSXを持っています
スピードメーターをkph-EUに変更しました(mph-USから)
GPSを使って表示を修正したい(私はT3Tec Nsx Meter Testerを持っていない - 残念ながら)
私はVR1がどう変わるのか、VR2がどう変わるのかを尋ねたかったのです。
例:スピードメータースケールのゲイン調整、オフセット、直線性
Mr.Toyoizumi says
なるほど。
2個のボリュームは
低速レンジと
高速レンジです
オフセットとゲインの関係もあるけれど。
まず、120km/h程度でVR1を調整し
40㎞/h程度でVR2を調整していきます
できれば
高速側は
速度が高いほど誤差は少なくなります
I do not know how to express my gratitude to Mr Toyoizumi in words.
I am asking for a hint
At first let me state that my Japanese is quite basic (my brain seems to have issues keeping more than two languages at a time - or I'm simply too old ..)
After correcting some of the line feeds (to make the job of Google Translator a bit easier) it came up with a reasonable result, which i tweaked further:
I use a Google translator, but I do not know if you understand
Can you write in English?
In Europe, I can not explain to me what the VR1 and VR2 potentiometers for PCB speedo are for.
A word of respect
I do not understand English.
The Speedo PCB?
Did VR1 and VR2 speed correction problems arise?
I have an Acura NSX
Changed the speedometer to kph-EU (from mph-US)
I want to fix the display using GPS (I don't have T3Tec Nsx Meter Tester-unfortunately)
I wanted to ask how VR1 changes and how VR2 changes.
Example: Speedometer scale gain adjustment, offset, linearity
I see.
There are two potentiometer, one for the slow and one for fast speed range.There is an additional relation between offset and gain.
At first, adjust VR1 at about 120 km/h and VR2 at about 40 km/h.If it's possible use a higher speed. The higher the speed, the lower the error. (probably relates to VR1)He probably suggested 120 km/h as the Japanese highway speed limit is 120 (my guess, to not encourage speeding) but a higher speed would be better for accuracy.
From the T3TEC screenshots that Kaz posted a while ago they do test with 180 km/h, it seems.
Regarding a thank you, this page might be of interest: https://www.livinglanguage.com/blog/...ions-you-need/
From my (foreign) experience, it's the thought that counts and not so much a perfect handling. If in doubt, rather use something simple than nothing at all
PS: Now I'm ready to be smashed to pieces for my limited Japanese but at least I tried

I have also just put this through my translator and this is what it came out with:
Good morning

SpeedMeter substrate?
VR1 VR2
Speed correction
Is the problem happening?

Mr.Toyoizumi says
I see.
2 volumes are
With low speed range
It is a high speed range
There is also a relationship between offset and gain.
First, adjust VR1 at about 120 km / h
We will adjust VR2 at around 40km / h
if you can
The high speed side is
The higher the speed the less the error

Colleagues,
I would like to thank you for your help in translating. I carried out the speedometer correction - I do not recommend running on the highway - it's dangerous. The future is better done with the help of the waveform generator. Since I have Aftermarket wheels (different wheel diameter) I wanted to reduce the error.
Thank you again for your help
