Good day to all,

I am a new 500SEL 1993 5.0L W140 onwer, I purchased this car since 6 months, I noticed after full general maintenance that I have a low performance, low acceleration between 1000-3000 RPM. So I am planning for ECU, especially I want to use Octane 91 instead of 95 and the ECU performance chip will tune that for you.

The follwoing Auction on ebay offer many ECU chips for MB:
