Hi guys. I have problem with closed loop in S300 manager. Car was tuned in open loop, and all works perfect. Problem is when I switch to closed loop, car start to shake, rpm drops, car goes full lean and dies. I tried all options, even tested on another ecu, but problem is the same! Can someone help me with this problem?

Re: S300 Closed Loop Problem
Don't use D14 as the input. Instead us the D10 or one of the other inputs if your ECU has the needed components.

Re: S300 Closed Loop Problem
Have any luck with this?
My tuner couldn't get this to work either whenever he turned it on it went 20% lean, so just left it open loop

Re: S300 Closed Loop Problem
I could never get closed loop to work correctly either, it works much better in open loop
