rsdoherty88 Posted November 23, 2022 Report Share Posted November 23, 2022 We are using innovate lc2, and everything works fine at idle and under load, but as soon as we let off the throttle, link loses the wideband signal, which is making the autotune feature nearly impossible to use because everytime it loses the lambda signal we have to restart the autotune feature.

Brad Burnett Posted November 23, 2022 Report Share Posted November 23, 2022 does it lose the signal or is it just going lean off the selected scale due to over run fuel cut? Maybe configure the autotune to disregard any value that is occurring on overrun? Quote Link to comment Share on other sites More sharing options...
Confused Posted November 23, 2022 Report Share Posted November 23, 2022 Could be Overrun Fuel Cut, which should be disabled during tuning. Also, check your Error High and Error Low values for the analog input, as I believe the Innovate uses the full 0-5v range for its output, with 5v being fully lean. Your question would have also been simpler to answer if you'd provided a copy of your configuration and a log file which has the issue present, because at the moment we're all just guessing without having anything but what you think is relevant.

rsdoherty88 Posted November 23, 2022 Author Report Share Posted November 23, 2022 Thank you everyone! I actually did figure it out last night that the error high value was set to 4.95, I set it to 5 volts and that seems to have resolved the lambda signal issue. Out of curiosity, why would I want overrun fuel cut disabled? Quote Link to comment Share on other sites More sharing options...
dx4picco Posted November 25, 2022 Report Share Posted November 25, 2022 For tuning purposes as you experienced Or for racecar to have a smooth transition of and on throttle Quote Link to comment Share on other sites More sharing options...
