Try reading in bootmode using Galetto for example. Title: Re: A4 B6 1.8T BFB Reading ECU flash memory failed Post by: maxx888x on June 20, 2015, 01:39:43 PM when I try to read at Galletto, I get the message: "Change speed error"
Title: Re: A4 B6 1.8T BFB Reading ECU flash memory failed Post by: nyet on June 21, 2015, 01:18:11 AM Answer the question. Is the ECU stock or tuned?
You DID see this message, did you not? "Validation failed, ECU reports RequestUpload was rejected. RequestUpload may have been disabled by aftermarket engine software." If the ECU isn't stock, don't bother. Flash over it or get a spare ECU. Title: Re: A4 B6 1.8T BFB Reading ECU flash memory failed Post by: eibxmatic on June 21, 2015, 03:50:30 AM Answer the question. Is the ECU stock or tuned? ive the same issue. my tune is not stock. is there any way to read the ecu anyway ?. like with a eprom programmer ?You DID see this message, did you not?

Yes you should be able to read your aftermarket tune even without desoldering flash from the ECU but most of the time it is just better to start from scratch as those tunes are of unknown quality and sometimes the changes made are really hard to understand (if you follow NefMoto guides you can destroy your engine). Title: Re: Sv: A4 B6 1.8T BFB Reading ECU flash memory failed Post by: technic on June 21, 2015, 07:54:48 AM There are some important tweaks regarding fueling that needs to be done in BFB and BEX aswell

Haven't ran over the answer yet. Because of that I was asking. Yes it is not recommended to modify aftermarket. But my tune feels good and i think it is good for learning purposes to compare stock to aftermarket file with damos.

All the knowledge what should be changed is already covered on this forum (including map locations for most popular ECU variants). To find how to change it you should log your own car as there are no 2 same engines in the world. In the beginning you adjust one parameter and log to check how does it all work together, if everything looks proper you move to next parameter and so on... Many tunes just change 2-5 maps (and some of them are changed badly). I am quite sure you can work out tune better suited to your car on your own... If you really have to read it, just read threads regarding reading/writing ECUs (especially those regarding bricked ECUs).

If you're new enough to need examples, you're also new enough to not be able to differentiate good from bad.

Because it is hard to reconstruct the changes are made which can result in damaging the engine. The only thing that is interesting for me on my aftermarket tune is. What changes are made at kfzw and lrdxn especially at 3000-4000. I've got very aggressive torque under wot in that region and I want to avoid that when building from scratch. Reading a tune you know how it is affecting your engine is in my opinion a good way to get a "feeling" for what you can expect in the street while you still sit behind your screen. So why should I throw away the opportunity ? Even after logging I see the tune can't be a bunch of crap. I've got a good up building boost and also almost no ignition retard on wot at 5500+rpm. Title: Re: A4 B6 1.8T BFB Reading ECU flash memory failed Post by: tjwasiak on June 23, 2015, 06:37:23 AM The data you got in your logs should be sufficient to reconstruct what was done to the tune :D
Most of the time "off-the-shelf" tunes have stock ignition advance maps, with LDRXN/ZK changed, sometimes minor changes to MIOP/MIRL (have seen some strange trickery done to them) and thats all most of the time.

Couldn't agree more on all points. Title: Re: A4 B6 1.8T BFB Reading ECU flash memory failed Post by: turtlemann14 on December 12, 2015, 07:38:22 PM only reason i am posting here is that i have the exact same issue except i don't believe my car has a tune on it still running 10-8 psi when i am using the EBC and i see no marking on the ecu (it would have to been flashed on). is there anything else that could cause this? i have verified that pin 121 is at the same voltage as the battery 12.2v@time of measure
anything else i am overlooking? also i had no luck with vcds-lite last night ------- fixed it now talks i may try the me7_95040.exe to copy the data tonight |
