Baro Flag Question
I have hopefully a simple question in regards to one of the baro flags. Specifically "MAP A: set=Use VE Multiplier Table For VE Baro Adjustment, clear=Use Altitude Adjusted MAP For Vacuum VE Lookup (Boosted No Baro Comp). For a non-boosted 1 bar MAP I would check this setting if I want baro con...

Re: RPM Dropping When Slowing Down
So it seems the issue was just low VE in the 40KPA area of the table at low RPM. After I adjusted the kinjflow and lowered the VE all around on the table. I was able to adjust the VE table in the areas more and resolve the lean spot issue on decel. Thanks for everyone's input on the issue. Took more...

Re: RPM Dropping When Slowing Down
I rebuilt my tune from scratch. Figured since I was troubleshooting this issue I would fix the high VE issue along with it. Before the low end of my VE table was 60-70s. Now the low end of my table is in the 40-50s by adjusting the kinjflow rate to richen up the whole fuel table to lower the VE. I d...

Re: RPM Dropping When Slowing Down
Did not have time to get to testing it today life got in the way. I will try tomorrow or the day after and update you guys when I am able to do it. I am going to hit it with 100VE in the 40KPA cells at 600RPM where the RPM is dropping and force open loop. If neither of those issues fix it then I am ...

Re: RPM Dropping When Slowing Down
In the screenshot I posted it has narrowband o2 volts (0v to 1v) and wideband. The O2 milivolts is in the top graph. The narrowband o2 is swinging to 0mv when the mixture goes lean 16+AFR and like I would expect when it is very lean like the wideband is showing. From what I understand it does not go...

Re: RPM Dropping When Slowing Down
What you are saying is that the narrowband o2 sensor is sending improper readings to the ECU causing the the fluctuation in idle as I slow down and come to a stop? When I look at the logs I am always looking at the wideband o2 to make changes to the VE table if I need too. When I look at my log it l...

Re: RPM Dropping When Slowing Down
My throttle body actually has the factory plug still on the back of the adjuster bolt for the throttle body blades. As far as I can tell it has never been removed and adjusted. Yes I am using a wideband o2 sensor with narrowband emulation. I am using the spartan 2 from the 14point7.com. Looking at t...

RPM Dropping When Slowing Down
I am running OSE12P on my 165 ECU here in the US. My car has a chevy 350 with a manual transmission. I am having a small tuning issue when I slow down my RPM fluctuates. My idle is set to 750RPM. As I am slowing down to come to a stop my RPM drops to 500-600RPM and then hunts until it finds the idle...
