Re: Car will not follow commanded AFR

I'm commanding 1.021 lambda in the low end and my car follows it. What I did was remove the secondary O2 sensor and remove some DTC errors related to it to avoid the ECU thinking that it needs to heat the catalytic converter. @mituc; 1.021 vs. 1 lambda means that in a 125 km/h. trip I'm seeing 9.8 l...

Re: AFR going to low ALWAYS without KR

The thing to note here is that I get the commanded timing. Which puzzles me even further. No you don't, the actual timing is lower :) Yeah, you are right just, checked again the section that I linked in the OP and I'm around 1º less than commanded, it makes sense after crossing BAT with 90º ECT I'm...

Re: AFR going to low ALWAYS without KR

Those are the lines in that huge logs where you have some WOT pulls :) When looking at a huge log like that it's pretty inconvenient to locate the relevant sections which are relatively small. That's why my link was zoomed in just to a precise section. :-P You're not seeing knock because there is n...

Re: AFR going to low ALWAYS without KR

For those who want to take a look jump directly to like 2772, 5351, 5774, 6785, 6816, 7154. Sorry @mituc; what is that? Once you step into the section of the ECT/BAT retard (knock or no knock) tables where the timing retards are not zero you will also get this AFR enrichment as an unwanted bonus. T...

Re: AFR going to low ALWAYS without KR

Just flashed a map with all the fuel tables including knocking an overload sharing the same values, same outcome, ECU is demanding 0.715 lambda (10.5:1 AFR). There is no knock on the logs. Are High BAT/ECT Retard No Knock & Knocking forcing Min Desired lambda once a cell is not 0 for a given BAT...

Re: AFR going to low ALWAYS without KR

Please post or send a copy of the tune and a log showing the behavior. Yeah, of course, my bad Steve. Find attached the map, please realise that WGDC is 5% lower than in the logs I'm sharing because I just gave some extra pressure to my BNR spring, the rest is exactly the same. Full log: http://goo...

AFR going to low ALWAYS without KR

Hi there, Since a while my AFR is always going pretty rich to 0.715 lambda which is my Min Desired Lambda value without any reason for it. I'm commanding 0.7347 in Open Loop at 6,000 rpm. and I'm not seeing any knock, my boost (21.5 psi) pressure is what I command and even my ignition advance (10º) ...

Re: ECU targeting Knock tables AFR in place of No Knock tabl

When the ECU starts pulling timing based on the high BAT table(s) it will also enrich the mixture. So that is why the AFRs are richer than the actual target value. And when that happens, when you look at the logs it's pretty easy to mistake the actual AFRs with the stock knock values because they w...

Re: ECU targeting Knock tables AFR in place of No Knock tabl

Take a look at the "Ignition -> High BAT/ECT retard no knock" table and see where the current BAT temperatures throw your timing values. You will not see these values as knock retard in your logs as it happens sometimes with the overload retard or when you approach the fuel cut boost limi...

ECU targeting Knock tables AFR in place of No Knock tables

Hi there guys, Long time not visiting this forums! :-( I'm experiencing a weird issue, and it is driving me mad, these are my WOT AFR tables: https://dl.dropboxusercontent.com/u/9746660/VersaTuner/Screen%20Shot%202015-07-04%20at%208.51.56.png https://dl.dropboxusercontent.com/u/9746660/VersaTuner/Sc...
