overlap Posted July 29, 2022 Share Posted July 29, 2022 Evening guys. If I had carried out the above open FG loop procedure but had left some small numbers in the "boost integral gain" auF0286 , would this be why im seeing 5-10% duty cycle even with zero DC in the auF16463 wastegate duty cycle table? Im yet to get a chance to test it. Cheers Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted September 12, 2022 Author Share Posted September 12, 2022 This is good information worth reading in relation to boost control Quote Link to comment Share on other sites More sharing options...
overlap Posted November 10, 2022 Share Posted November 10, 2022 Can we still effectively run an over boost shutdown in open loop boost control ? Quote Link to comment Share on other sites More sharing options...

Set it to some low number and make sure it goes into limp mode. You can also use tmap and boost sensor max voltage. 1 Quote Link to comment Share on other sites More sharing options...
overlap Posted February 1, 2023 Share Posted February 1, 2023 Which part of the open loop procedure causes applied dc to the solenoid at idle and stalled? Quote Link to comment Share on other sites More sharing options...
