I made several additions to Pazi88's ECU Definitions v0.35 Beta1 file.

They are as follows:

AD + CA Full & Partial Binary Only
C6 to come later...

Added some extra maps and scalars:

- added Brake Test Switch Configuration
- added Throttle Body Gradient Threshold
- added Throttle Body Speed scalar
- added Ignition Retard Part Closed Throttle
- added Intake VANOS Advance & Retard Delay Modifier Maps
- added Exhaust VANOS Advance & Retard Delay Modifier Maps
- added Minimum Vehicle Speed for Antijerk
- added Maximum Vehicle Speed for Antijerk
- added Minimum Engine Speed for Antijerk
- added Maximum Engine Speed for Antijerk
- added Engine Speed Modifier During Clutch In
- added Idle Ignition Modifier During Clutch In
- added Idle Air Control Valve Cold & Warm Maps

The IACV map seems to be smaller on CA and C6 than it's in AD. But I already made fix for that and also included C6 maps in addition to those. And included my other additions. I will post the v0.37 bit later. I will just check that I didn't make any mistakes merging two files. Just a heads up that hopefully we don't do much duplicate work.

Heck yeah, keep these files growing! Im excited to see what additions you’ve made Pazi

I noticed that there are several different IACV table/maps, but if im remembering correctly the two (warm/cold) maps I added were the only IACV maps that looked like they were percentage based.

Well now that I looked, there isn't much But here is it:


v0.37- some level of 011025 support added
- added MPG gauge correction factor
- C6 support added for previous additions from 323toslow
- C6+CA ICV maps fixed

v0.38

for AD, C6 and CA:
- Camshaft Initial Position
- Camshaft Duration
- Vanos Initialization Hysteresis

Hi, just set the decel timings to -19 or more degrees. It is my friend`s old 320i m54b22 with res and muffler delete. You can deactivate the fuel overrun cut or just blip the throtttle to make it pop. Cheers.

tks a lot for this version, i do a lot changes in my 328 98/99 AD.

But i have some issues with the Lambda FeedBack.
the virgin map had the option 1 marked. The car doesnt had the second pos cat lambda.
after the first upload, without editing the Lambda Feedback, inpa registred a Post Cat Sonda Error Bank 1 and Bank 2.
with the v0.38 the error doesnt desapear.

have any idea?

i an using the chipster mss to download a partial map.

Hello To all

Does the MS42 have the following map: ip_ti_pvs_vo_fac_vo

This map is in the MS43 bin but i could not find a similar map name viewing an MS42 512kb file/damos in wols.

Here is the explanation i received from someone:

“Map modifies PVS which is basically a measure of final torque demand. Input from the gas pedal goes through numerous maps & modifiers before the engine actually makes a change to throttle position & the rest of the motor's functions (injection, ignition, vanos, etc etc). It modifies PVS based on current valve overlap as calculated by [(intake camshaft centerline - exhaust camshaft centerline) /2] based on overlap ("vo" value in ms43 definitions like "ig" = ignition)”

“By setting all values to 1, there is no more automatic EGR based on vo. Because this map had 2 purposes, it not only allowed lower pvs values during cruise (saving fuel) but it also killed any tuning attempts by the aftermarket to find exhaust scavenging via VANOS because it would haul PVS back by as much as 15%, negating your gains. So by manually tuning the desired cruising rpm EGR effects into the fuel map while leaving the high rpm overlap unaffected by torque decreases because of (purposeful) ecu limitations. “

“Great trick by the engineers so even if you figured out the VANOS maps, you still had something that would limit your gains on the top end”

Does anyone know if the MS42 has such a map?

So it closes thorttle flap on high rpm or what? Is it seen on log? I have not noticed that kind of behaviour in ms42.

I honestly do not know. I decided to post it up here to see if anyone here knows about this. If the above statement is correct, adjusting that map would enable gaining some power.

Hi, I've found this map some time ago, but I didn't check it yet. I thought that maybe it's connected with 8 VUE maps. If any one would like to check if it works as you described - the map name is "KF_TI_DK_VUE_FAK".
Please share your experiences.

Hi Ecru

I am not at home right now to check my computer but is the map you mention in the latest MS42 definition file? If not can someone add it and i can test it I do not have proficiency defining maps

Well, unfortunately I can't, I'm not very familiar with RR definitions. But maybe Pazzi88 could help. In the mean time you can check the map by address. My ECU is C6 version and the map is placed under 0x4E075 address.

Hello to all

FYI


I did a short run with my new test tune (injection maps are stock except for a slight increase in the full load injection map) and the “KF_TI_DK_VUE_FAK” map values Ll set to “1” Feels pretty good. The engine has a noticeable “liveliness” to it. I cannot determine or quantify the specific improvement if any this map change has made but for sure there are no ill effects to the performance of the engine.

Thanks Ecru for your help!!!

What version you running?
