Title: Returnless Rebuilt to return Post by: Jim_Coupe on August 24, 2015, 05:34:46 AM Hi,
My fuel delivery system on my 3.2 Vr6 was returnless. I didnt like that solution. So i did a conversion to fuelrail with return. 4Bar Fpr. What happens to my FKKVS now? Title: Re: Returnless Rebuilt to return Post by: aef on August 24, 2015, 11:24:18 AM Take me7logger and log the following three variables:
nmot_w ;EngineSpeed ; Motordrehzahl te_w ;{EffInjectionTime} ; {effektive Einspritzzeit (word)} fr_w ;LambdaControl ; Lambda-Regler-Ausgang (Word) Then use roberts fkkvs fixer. https://bitbucket.org/guitar24t/fkkvs-fixer/overview Title: Re: Returnless Rebuilt to return Post by: nyet on August 24, 2015, 11:26:12 AM Start with all ones, log stft and go from there.

Ok ill try that.. Im trying to find the download button to guitars FKKVs fixer.. Must I register ?
Title: Re: Returnless Rebuilt to return Post by: Jim_Coupe on August 25, 2015, 04:53:10 AM Ahh Found it :) !!! BTW... Do you have any tips on a program that can give a nice presentation of the Me7 Logs?
Title: Re: Returnless Rebuilt to return Post by: Jim_Coupe on August 25, 2015, 04:58:48 AM Choose FKKVS = A copy of my FKKVS table from IE Tuner pro.. Smoothing factor = Interpolation ?
Title: Re: Returnless Rebuilt to return Post by: aef on August 25, 2015, 05:40:48 AM You have to set your FKKVS at all 1 at first. And check the RLFS like the pros said allready.
Then you have to start the logger and drive for lets say 20min with nearly all conditions. Then use the log and your fkkvs like it was when you logged (1s) with the fixer tool and leave the smoothing stock. Its a bit tricky to have the files in the right format. Check out the sample files he provides with the great tool. After you have done this and you have a new FKKVS Table in your file do a wot log and check out your AFR actial vs requested. It should match now. BTW: do you know the edit button. No need to spam the thread :P Title: Re: Returnless Rebuilt to return Post by: spacey3 on August 25, 2015, 05:48:30 AM Ahh Found it :) !!! BTW... Do you have any tips on a program that can give a nice presentation of the Me7 Logs? ECUx Plot as per Nyet's signature ;) (If you're on about viewing logs in general of course!) Title: Re: Returnless Rebuilt to return Post by: Jim_Coupe on August 25, 2015, 06:30:40 AM Ok, Like Nyet said.. Set all to "1" then check STFT.. Makes sense.. then i would see the deviations and get a good picture of how it compensates.
So with the log the FKKVS fixer can se where the ECU compensates and then genereate a new table based on the process picture.. Am I right ?

Unfortunately, it doesn't have a heatmap plotter :( Also consider disabling LTFTs for now. Title: Re: Returnless Rebuilt to return Post by: Jim_Coupe on August 25, 2015, 10:21:49 AM Yepp.. The LTFT are already accidentally disabled hehe.. But thats another thread :o) ..A thought struk me.. Why doent STFT handle every thing? Or Does the engine live a dangerous life if one just rely on the Fueltrims?

If you are close enough they will, but you might see bad gas mileage because it isn't instantaneous. If you aren't close enough, you'll throw a trim code and go limp. |
