Re: M3.3.1 413
I´m stuck to my autotransmission and Motronic have been causing me some problems with torquehandling. After lots of investigations in plenty of aftermarket ecu I´ve found out that Links Pnp G4+ Extreme for M50TUB25 is already prepared for functions and maps regarding auto,no other known ECU is suppo...

Re: M3.3.1 413
Trying to clear out maps for A/T transmission,I´m driving a modified ZF5HP18 and want to controll linepressure. In XDF I can find: 0xE065 8bit PT Load map 0xE0B3 8bit WOT Load map Are there more A/T related maps? Transmission TCU needs load-value to controll out correct linepressure vs actual torque...

Re: M3.3.1 413
Thanks for reply.
As you understand I would like to modify closed loop parameters,any ideas in which map-area they are located?

Re: M3.3.1 413
Looking for maps to modify lambdacontrol,would like to have lambdacontrol/adaption active below X load and disabled above Y Load. It would be nice to have lambda-adaption active at cruisespeed and deactivated on boost. Also noticed that changing AFR-target value doesn´t have any effect on my car.Hav...

Re: M3.3.1 413
Turbo is by now replaced.
Bought a Link knockblock,conntected to knocksensor I can hear sounds from engine,knocking,even small knockings are heared very clearly.
Great tuning tool!

Tunerpro do not trace WOT maps! Trace PT maps and when tracing light turns to "waiting" you should be in WOT map if everything is ok eg not MAF over limit and so on. I forgott to turn off Lambda adaption,3 full WOT sweeps on third gear resulted in lean mixture,aboyt 14,5 on WOT.Now I have ...

Re: M3.3.1 413
No problem to read livedata with autocom,connected to 20pin round.
Very useful to read actual igntion no matter what igntiontable DME is reading,also no matter knockretarding.Autocom will show you realtime ignition.
Without autocom youre blind and you will only be guessing ignition!

Re: Rescaling K-value and AT-question
Some testing done.
Somehow I need to rescale load-axis.
Due to lower k-value for injectors it now only hits about 50% of load-axis.
Can anyone please advise me how to rescale load?

Re: Rescaling K-value and AT-question
540cc/190cc=2,84 is the difference for new injectors.
K value 1.0/2,84=0,39 new k value
Still wondering if I need to rescale every single map with Load?Or just fuelmaps?
