Overclock stock ECU
 

I've run this overclocked OEM ECU on my CSP car for about 2 years in order to increase the redline by 10%. This is a Federal ECU BP5R that works in my '2000 NB and might work on other year NBs.

Before buying this ECU please understand that you will not be able to connect to OBD2 through it any longer (which is normal for overclocked ECU). So I would generally recommend it to an autocrosser looking for higher redline. Of course you can swap to regular frequency crystal and use it as normal ECU as well.

The only reason for sale is that I've gone to full standalone Megasquirt.

Asking $150/BO.
