Re: BOSCH LSU ADV configuration

I have checked the output functions and see there are some configs for lambda heating. However Im unable to see how I can implement something similar to what the ADV or 4.9 spec require. Both have dependency on time on startup and afterwards. Any ideas if this can be configued somehow using CM maps ...

Re: Speed reading way high

hi. did you managed to fix this ? Syvecs mentioned the high tooth count is something to do with scaling on that particular PnP application. My speed reading are not spiking when driving, very stable.

Re: total timing drop during cranking

The lambda issue is new on past logs it was perfectly fine, but with the same torque limit issue when not starting. I will recheck the lambda now. 2023-09-01 14-09-10 plus 0h00m00s S7#12516.SD and I c...

I have started getting sync error just a bit later when runmode changes to running. looks like reducing timing during the start make the ecu to not sync properly.

Re: secondary injection on DI for MAX DI .

thanks everyone. so im concluding for future readers if the secondary injection pins are configured in pin assignment and the max direct injection time is setup we get secondary injection kicking in, but split need to be 0 all the way ? what i dont like in this scenario is that your secondary is off...
