you are probably right mate, so I am glad you are taking an interest
But if there was plenty then it could be plausible , and you the Chip reader/writer would make quite allot more cash or even heaven forbid give your clients a better deal... which would mean more clients of course
With that equipment u can do pretty much any car till 2008/58 after that they went to anti tuning protection edc17tricore Ecu that are a lot harder to do
I only deal with diesel cars as that were u see the best bhp and economy gains
After 58reg equipment about 2k more expensive but alot higher risk as Ecu has to be opened and effectively hacked so anti tuning protection is disabled so u can read and write Ecu
But 1 little mistake or miss hap = £2k + worth of repair costs at a dealership
I for 1 don't bother with tricore Ecu as the equipment is pretty new and there are bugs and manufacturers are always trying new things to block us out
If u f*ckup a pre 58reg Ecu u have a 98% chance of either fixing it or effectively cloning damaged Ecu into a secondhand Ecu which is a lot cheaper than a f*ckedup tricore Ecu
I have killed Ecu before and most cases all I had to do was flash a good original file with same software number and part number then reconfigure to match car using dealer level tool
U can't do that with tricore Ecu as they have OTP areas in micro + flash were. They only programmed once and u can't write over them
So u mess up u need a brand new Ecu
here is a tuning guide that i got from a guy who modifys the files for me
he said he read it and understood it for basics and then trial and error with alot research to get to were he is now
im still trying to make heads or tails of it as its very complex and as i have my hands in loads of different pies not enough time
to do a good remap u have to do the following:
be good at maths to work out some formulas
understand how that particular ecu works
understand how that particular engine performs
understand how to find maps and modify
understand were to modify the maps
understand were to find necessary info from file to get axis data (2d/3d/table)
understand how each limiter in the file works and if its linked to anything else
understand what to log and look out for when testing a file
understand the physical limits of the mechanical hardware in that particular engine / car
there are alot of sub dealers out there ! that can read and then add modfied maps and protocalls , but all the filles are modified by a select few companies ! and even fewer free lance gurus !it takes years of training and pratice to sucsefully modify a map file without actualy causing excessive stress on the engine components or by bricking ecu with damaged files
I agree 100% with FES_786. The chances of any random download file working are slim to none. The amount of maps and the complexity of tuning a specific file to work with a specific hardware set is daunting. Plus you wont know if the checksums were even corrected after someone fiddled with it and flashing such a file to your ECU will brick it right quick. I wouldnt touch this unless you know what you are doing, and if you do then you wont need ebay files...
i have lots of maps but not for the a3 1.6 8v 105hp petrol engine, i know power increase can be at most 8-10 hp, but is there anyone that have this type of remapped ecu file?
