SR20DET KSROM Ecu tune. JAPANESE TRANSLATION!?

[elucid]

So my ecu has always had this mystery switch, have no idea what it does. Well i was doing a small car project and removed the ecu, upon closer inspection i saw that it had a stamp "KSROM" I know they are a pretty reputable ecu tuning company. But does anyone out there have any information on what this switch actually does.

Could also use a bad ass who can translate japanese. Here's the label.

Dual maps one is prob moderate and the other more aggressive race gas e85 more boost something along those lines be careful japan has higher octane then the us they like to spike the timing way up for the octane over hear ull get major detonation with out rce gas or 100 octane or better

ノーマル切り替えスイッチ（ロムチューンとノーマルロムをスイッチで切り替えできます。）

２タイプ切り替えスイッチ（２タイプのデーターがスイッチで切り替えできます。）


このコンピュータ本体は、充電式のバッテリーがセットています。
コンピュータのフタを間けるとスイッチがＯＮになりロムに電圧（５Ｖ）が逆流されてロムのデーターが破損し コンピュータ本体もショートする回路がセットしています。
コンピュータ本体の保証シールを少しでもがしたり、コンピュータのフタを間けた場合はどのような理由でもロ ムに関するサービスは，ー切受けれません！
（最近、ロムのデーターをコピーしたり、破損させたりする場合が多い為です。）


スイッチは、必ず、エンジンをＯＦＦにして３０秒後に切り替えをして下さい。又、走行して３～５分間ぐらい はデーターが切り替わらない場合があります。

(I can be switched on the switch normal ROM and ROM tune.) Normal changeover switch

(I will be switching on the switch data of two types.) 2 type selector switch


The computer body, rechargeable battery has been set.
I set the circuit main computer unit also short of ROM data may be damaged voltage (5V) is flowing back into the ROM switch is turned ON when the kick between the lid of the computer.

The service on the ROM, not received over cut in any reason if even a little or a warranty seal of the computer main body, was only between the lid of the computer!

(Recently, it is because when you want to copy the data of ROM, or to damage in many cases.)


The switch, be sure to switch to the 30 seconds Turn OFF the engine. In addition, you may data does not switch is about 3-5 minutes, then run.

I thought japan used the ron system . So 100 ron is about 95 octane here.

( RON Octane Rating x 0.95 = AKI Octane Rating )
98 RON Octane x 0.95 = 93.1 AKI Octane (US measure)
100 RON Octane x 0.95 = 95 AKI Octane (US measure)
