Did anybody try to disassemble VDASH? I tried but couldn't deobfuscate it. I have not enough experience with .NET disassembling. Other option looks like just buy some reflashing and grab CAN messages. VDASH developers just grab these protocols (with SBLs) from dealer early. Or just stole VBF files from dealers VIDA.

I never played with VDASH so for fun I thought I'd download it. Then it detected I had visual studio open and force closed everything without saving, so that was pretty annoying. Looks like this is some complex ass software that does a pretty good job of protecting itself, and I already gave up on it.

vdash used to be more helpful at changing a bunch of shit but now everything is behind a pay wall -_-
3-4 years ago it was so much simpler but still useful

how do i transfer this 0 280 218 067 for RS4 MAF HFM-5-9.7  and 5120 hack stuff from this well defined qhhj over to my qphj without losing my mind?
im dyslexic af and throw up after 15 minutes in ols
i need all the maf stuff for my gphj

i got the tvub - n00b question.. when i change it to 5 rows as to what my injector sheet has... it doesnt look right? idk....
can i just keep it 1 row and be fine?
and the krkte to what i believe is correct

and yes i did the equation 50.2624*(displacement / cylinders) /(cc*.684)

tested it with the examble mynet or someone had and got their answer so i plugged mine in

This will get you started... not sure why you want to do 5120.. i suggest getting comfortable with map changes before making it overcomplex., I'm personally at 15 hours on my 5120 for 50whrj its been an ongoing project for the last 2 years. im unsure of an easier way

for tvub copy over 58 psi row and call it good.

My forays with Denso are just so I can learn a bit more. In the future I am planning the following build: 2.3t5 block + 2.5 head. I plan to shim the block just in case. I have one serious issue and that is, that the electrical installation is vastly different from Denso to Bosch. Then there's the need for a CEM to work with the BOSCH ECU.

actually at the bottom of the chart it says it flows 11% more on gas.....so 11% more on the 1178 is 1,307.58   so should i use that or is 1178 fine

Personally wouldn’t look much further than what it says in the chart


It’s important to log your fuel trims to ensure you set the krkte and temin correctly. With such large injectors are tricky to learn on

make sure you read up on fkkvs and utilize hiltons fkkvs tool.

There is easier approach to setting KRKTE. No need to use fancy calculators Smiley
If you don't change engine displacement just use this formula: NEW_KRKTE = (OLD_FLOW * OLD_KRKTE) / NEW_FLOW
No need to use factor with KRKTE. Just use pure HEX value from BIN (convert it to decimal for convenience).

It's important to use exact same units on both injector flows!
They must have the same flow unit (popular ones: cc/min, lb/hr, g/min) at the same pressure (popular ones: @3bar, @3.5 bar, @43.5psi etc.) and for the same reference liquid (Ethanol, n-Heptane, Gas, etc.)

Looks like your chart gives flow at 43.5 psi on ethanol (multiply by 11% for gas) in cc/min.
Now just find your stock injectors flow and "just" match units and you have your KRKTE.

Actually matching flow units is the most pain in the ass in this process Smiley

Then just paste new KRKTE value back to BIN and test drive the car and keep eye on fuel trims. If they are off in wide range then you have to shift your KRKTE.
You have to also recalculate KVB constant if you want cluster to show real values (the lower KRKTE the higher KVB proportionally).

I've made a lot of progress on the hilton source code, and I'm building a simple tool whose only purpose is to read and write ECU bins unencrypted using the DICE cable. Some testing is required, then I'll release the app and the source for whoever wants it. After that I'll look into building an encrypted bin decrypter. well, unless vollmer beats me to it Wink
