Title: s4 mbox tries to follow ldrxn instead of ldrxn + 300 Post by: Speedy_Driver_90 on November 22, 2020, 05:10:21 AM Hi guys.
i got a problem and i dont really get it... the ecu tries to follow ldrxn on point instead of ldrxn + 300. is there any map that could interfere? IAT are ok as we have less then 10°C outside. also tried to max out kfldhbn that it should not intervene. no ignition retard or other things that could suggest problems... i only got vcds to do logs. with vcds actuall boost matches the requesting boost. Greetings Max Title: Re: s4 mbox tries to follow ldrxn instead of ldrxn + 300 Post by: _nameless on November 22, 2020, 05:39:46 AM Hi guys. yawn. same shit from all the noobs. no logs, nothing they say makes any sense, killing safety maps... and still has no idea and overlooks the basics i got a problem and i dont really get it... the ecu tries to follow ldrxn on point instead of ldrxn + 300. is there any map that could interfere?

Greetings Max "Keep in mind, this is a rough approximation. It can be off by as much as 30% or more. It is dependent on a large number of factors including air density, temperature, elevation, and the alignment of the stars and the moon. Use this formula to get close, then adjust based on real world observations." y Title: Re: s4 mbox tries to follow ldrxn instead of ldrxn + 300 Post by: adam- on November 22, 2020, 06:26:38 AM Where does it say it's RXN + 300?

And again its higly affected by many things and relies on stock scaling... get me7logger sorted.

Title: Re: s4 mbox tries to follow ldrxn instead of ldrxn + 300 Post by: nyet on November 22, 2020, 03:39:15 PM i only got vcds to do logs. Start by fixing this. Title: Re: s4 mbox tries to follow ldrxn instead of ldrxn + 300 Post by: Speedy_Driver_90 on November 24, 2020, 06:04:41 AM Is there a "how to" on here how to log properly? I tried myself to use visual me7 logger but it didnt work at all...

The ECU doesn't follow that though, it follows RXN. What you end up is a result of what the ECU has done. Title: Re: s4 mbox tries to follow ldrxn instead of ldrxn + 300 Post by: Speedy_Driver_90 on November 25, 2020, 02:05:18 AM it looks like the problem is different from what i first thought.... i tried a few variations of rxn. no matter what i do max requested boost is always limited to 1 bar... could somebody look thru my bin to look whats wrong with it?

No. Post a log and stop breaking forum rules. Nobody here wants to waste their time on something that is going to be totally inconclusive. There is a reason there is a forum rule regarding posting bins and asking for feedback without logs. Post a bin, you'll be guessing for months, if not forever. Post a log, problem solved quickly. |
