[patchat88]

Hi everyone,

I start to build my single setup:

- borgwarner 88-75 .91 a/r twinscroll
- homemade quick spool valve
- siemens deka 630cc and all the fuel mod to max out the injector
- greddy map sensor 3bar


My question is about how to deal with closed and open loop of the stock ecu, did I need to remove the o2 sensor or a way to clamp the o2 voltage?

Thanks
