Hi all,

Today I had a secondhand bought chip installed on my car. Testdrive said mixture was way to lean at boost level +- 0,70 Bar. The Horsham (H-Dev) stage 1 should be good for 1.1- 1.2 bar boost.

We found out I have a 75F00 ecu and the chip mentioned 69F00.

Could this be working any way?

Or better buy another chip with right number?
