scottbrown,
so is "getting into" an ecu along similar lines of "hacking"? ie breaking there codes etc.
how long can/does it take to get past security? ie does it cost u alot of ur time etc?
No, its not so much hacking as investigating and drawing on other experts in certain fields to get a global solution.
On 99% of stuff we can just remove the eprom itself, put it in the programmer and extract its data...
Then we begin the process seen throughout this post of sourcing maps etc etc etc.
Once all that is done, we have found the maps and modified em, we cant just burn it back to a chip and rteplace it, as i presume most of you would expect?
Oh no.. we then have to get past the checksum security built into the ecu..
Alter 1 single digit in that file, and the ecu wont allow the engine to start....
the bit youve just read 5pages of, is the extremely simple bit
scottbrown,
wot if i turned up to a pre booked mapping session and u had never mapped a car the same as mine before?
Well we did an 04 Megane DCi on Monday and that took about 11hrs if that helps?
