I've located most of the maps etc that require changing (got 7 left to find, I think)
I'm using ME7.5 8N0906018H 0004
Are the ASM patches the same as required for ME7.1 8D0907551M 0002? If so how do I find the addresses for them?
Thanks

Does it need ASM changes?
Please, stick to 21 psi until you learn ME7 |

Hello,
Could someone clarify that I have got the 5120 hack working correctly, I'm pretty sure it's working but would just like a second opion.
The car has 550 injectors, 4Bar FPR, hybrid turbo, full 3" exhaust & bigger TIP & air filter, FMIC & extra external fuel pump.
I'm seeing a fraction of a second boost spike on throttle let off, should this be expected running basicly a base factory map (factory map has edits for 550 injectors & 4Bar FPR) with these mod's?
In additon to attached files I'm seeing 1000mBar for measuring blocks 115 at idle for both pressure readings.
Thanks

N249 still there.
It's something to do with the N249 control and the 5120 hack as it was working fine before the 5120 hack, must of missed a map or doubled one when should have halved it or vise versa.
GWPLDU, LDUVS??

Uhhh.. were you only getting 50% throttle before you made these changes?
The fact that you're seeing sensible pressures after correcting the factors of pressure variables in the .ecu file suggests to me that at least some of what you've done has worked... but you either screwed something else up or started with crap.
The thing is, how are you or anyone else going to come to any meaningful conclusion when you throw 5120 hacks into a bodged 'base map' and take a single log??
Step by step:
* Create a map that works
* Log it
* Create a 5120 version of that map
* Log it
* Fit new MAP and change DSLGRAD, DSLOFS, whatever
* Log it
At each step: stop, think, analyse
Can you donate your engine to a museum or something? How has it lived this long?

Boost spike on let off is "normal"
My S4 done that in stock form, with k04 stock map and same with 5120... I even throw a new n249 without any change...friends RS4 same same story.
Some cars have no boost spike, others have, go figure...

Aardshok, I think you are getting me mixed up with someone else?

Your right, I'm confused now???
The car is going fine, definitely not running at 1/2 throttle.
Some by product of the 5120 scaling? Edit the .ECU to correct?
I think I may have located the N249/boost spike issue, not scaled the KFSDLDSUA, I'll try it out & see what happens.

Don't ignore my comments about changing too many things. Take a step by step approach or you'll never know for sure what effect your changes had.
Your throttle may well be only partially opening - this means that it will close faster and N249 will have less time to react and cause boost spike when lifting.
That could all be bollocks but you can't know for sure unless you isolate all changes.

Thing is you can't really apply the 5120 hack one piece at a time, I think it's got to be something with the hack as it's exactly 50%.
Also it's a factory base map just with the 550 injectors & 4Bar FPR edits, with the hack on top, so no funny business to start with.
I'll see if I can find some of the 5120 logs posted and see what thier throttleplate angle looks like.

> I think it's got to be something with the hack as it's exactly 50% It's not exactly 50%, it ramps up very slowly from 25%, peaking at 50%... very different. Yeah, I'm done. Good luck |

Think I've found the answer to the throttleplate issue, Mr Armageddon & Mr Boobietrap had the same issue (I'm assumming they are Mr's).
Mr Boobietrap wrote,
"my throttle plate was not opening to 100% on WOT.
Turns out there is a map called KFPLGUB which is used instead of ambient pressure for calculating pressure ratio across the throttle plate (used in throttle maps) if CWPLGU = 0.
Apparently on most cars CWPLGU = 1, hence this map is not mentioned in the 5120 hack threads, but on mine this was set to 0.
I think the solution is to either divide both the axis and the table by 2 or change CWPLGU to 1. I've done both just to be safe and now the throttle behaves correctly."
The above together with the cahnegs to the KFSDLDSUA map I missed "should do it" fingers crossed.
Might get to try t out this afternoon, but the weather bad at the moment.

Appears to be working after the changes above, throttle plate, following throttle pedal & no crazy boost spikes on let off.
It's not running particularly well under boost over about 15 PSI, as it keeps pulling it's self back, this is probably due to the factory map not expecting the hybrid boost/load & the fuel not being completely dialled in for the 550's IE FVVKS etc.
Have to confirm this by updating the map with the previously running settings.
