Is A Chip Worrh The Money For A Vr6 12v

People need to understand the sheer depth of "professional mappers" they speak to - many use a re-seller file from either their software manufacturer or their suppliers and these bigger companies or dyno operators often don't have the time to specialize in one particular ecu unless you pay for it - even I would pass one of the older Motronic 12V ecu's over to Vince if I didn't have weeks or months to reverse engineer one myself or someone didn't want to pay for a complete custom job on their stock ecu, simply because he has done that many so I know has various boost files ready etc.

Also, if, for example the OP - you are in another country, you should also see if he can patch in the boost controls or something and have a local dyno operator tune it once he's done it - not sure if he hides/IP rights his tunes though - would have to ask Vince and again, depends on how he mods the ecu's. In some respects, budding DIYers can probably already do that with the file I posted up and a bit of winols/tuneropro playing against your stock file and making notes of what needs to be coded roughly where. In fact, I can provide you with that actual file in a readable format for a small fee but it will need to be looked at thoroughly! However some mappers are already using it it seems!

"You can't boost the stock ecu!" - of course you can. Although these are V6 4motions, there are two reads of a BDE - bottom is stock, top is me patching in load axis code for when it goes past the factory 100% limit, about 1.2bar here, but there's obviously a lot more to it than that. Middle one however, is a pro tune, 500+euro's worth someone paid for, and as you can see, not only has the factory hard cap on the load axis been retained, which'll obviously cause problems under boost, it's also maxxed across the rev range unlike stock. The amount of money people I have talked to have spent on these things...... well it's no wonder some of you go standalone!

What you are looking at - bottom - stock BDE - top, same but you can see load axis changes I coded in (red box), don't have to do as many, can do the top two or three (blue box) for example - need to check the math and things like even the traction control at lower loads for example - middle is a "pro" ahem, map on single VVT V6 4motion - factory load still on and maxxed out, looks like stock torque values too, also looks like it is a quick cobbled together file (most tuners, to define a file will use things like a DAMOS or A2L file and they are usually pants or need a fair bit of modding unless you can get a good one exactly for your revision). Proper reverse engineering can take days, weeks or months even though and so costs a lot done properly!
