Title: RS4 B7 Kompressor: problem with ignition advance Post by: s-company on February 15, 2013, 05:12:06 PM Hello!
i have to solve very tricky thing. i made remap for rs4 b7 kompressor, car runs very fine, but there is space for more advande ignition. the thing is, a stock rs4 makes 40 degree (full load) advande without problems, with kompressor, the car only makes 25 degree. you can write adavnce values as high as you want in the kfzw maps, the actual real ignition angle is ALWAYS nearly same low. there must be some correction because of high airmass, i dont have another explanation, but why? also there is absolutely no knock retard, sometimes with low rpm, 0,5-1,5 degree retard, but high load nothing. any ideas for this? many many thanks for every input!

here is the ori. changes with KFZW's does not work (1cb530-1ccbb0) also KFZWMN, KFZWMS and KFZWOP makes no sense to tune for my opinion... seems to be that some other maps are blocking ignition advance.. thanks.

attched my logs. but only air mass, ignition angle and load. i didn't log 20 and 31 because there is no ignition retard and lambda is good (full load 0,8-0,84) BR Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: s-company on February 16, 2013, 07:52:57 AM sorry here is the log..
Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: matchew on February 16, 2013, 09:50:31 AM Can you log block 211 and 142?
Do you have any fault conditions? Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: s-company on February 16, 2013, 09:58:57 AM ok i can log these blocks.
no there are no faults... Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: matchew on February 16, 2013, 10:48:52 AM just to clarify, have you turned any faults off?
Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: s-company on February 16, 2013, 11:01:02 AM yes, i turned off faults concerning cat..
Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: jooo on February 16, 2013, 11:53:27 AM hello! You have access to a correct damos for this ECU? First guess would be that it is not KFZW you are tuning. Have you checked with idapro?here is the ori. changes with KFZW's does not work (1cb530-1ccbb0) also KFZWMN, KFZWMS and KFZWOP makes no sense to tune for my opinion... seems to be that some other maps are blocking ignition advance.. thanks. BR Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: airtite on February 16, 2013, 12:01:25 PM I will be watching this with interest.
Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: s-company on February 17, 2013, 04:08:20 AM i have no damos, i think its hard to get, but i am 100% sure kfzw's are at 1cb530-1ccbb0...

First guess would be that it is not KFZW you are tuning. Have you checked with idapro? You might want to look at the file before making statements like the one you did above... The area s-company has posted does correspont to all the kfzw maps. Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: s-company on February 19, 2013, 04:32:53 AM Can you log block 211 and 142? Do you have any fault conditions? attached the two blocks.. BR Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: matchew on February 19, 2013, 12:59:54 PM Intake tumbler flaps have been removed from the car? the system has an error on it.
Why is there a difference in the 2 air flow numbers? what boost are you running? I fail to believe its >1.5 bar. It seems you have atleast 2 error conditions being set. Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: s-company on February 19, 2013, 01:41:43 PM yes they are removed.. (makes not more ignition advance if it is not removed)
the boost is just a calculated value, car has no pressure sensor... no rs4 b7 do have a pressure sensor.. Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: matchew on February 19, 2013, 02:43:11 PM yes they are removed.. (makes not more ignition advance if it is not removed) So when I asked you about error conditions, u chose to ignore this? the boost is just a calculated value, car has no pressure sensor... no rs4 b7 do have a pressure sensor.. Im very well aware of what it is, it is calculated manifold pressure. I cant help if the information that I ask for is only what you think I want to know.... Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: SVSPORT on February 19, 2013, 05:32:42 PM I have to ask you again..
Do you have any logs for knock,lamda,injectors,pumps,torque... ???? Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: s-company on February 20, 2013, 12:53:53 AM RIGHT LOGS
here is lambda and knock. Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: s-company on February 20, 2013, 12:55:09 AM here is injection time.
i wil make more logs in the next days if there are some required.. Title: Re: RS4 B7 Kompressor: problem with ignition advance Post by: nyet on February 20, 2013, 10:17:54 AM Please don't post excel files. They're useless.
