Hello!

Im new here.

I have a JDM AP1 which is limited to 180kph. I have an APEXi RSM installed enabling my AP1 to accelerate over and above the 180kph limit. The meter however, stops at 180.

I recently installed an SOS SC and got the AEM EMS. I was thinking that the stock JDM ECu is responsible for stopping the meter to rise above 180.

After installing AEM, my AP1 can still go beyond 180kph, however, my meter still stops at 180.

I am trying to exhaust all possible answers solutions before buying myself a USDM gauge

Any thoughts? Thanks
