As MaxiBoost asked me, if I could share all the hex addresses which are important for tuning,
i found the time to do that. So here it goes.

The following example is made with original Q4 101.04 chip.

There are 7 maps which are important:

1. Injection map
2. Ignition map
3. Turbo pressure map
4. Turbo pressure limiter map
5. WOT (wide open throttle) injection enrichment map
6. Injection timing map
7. RPM limiter map


1. INJECTION MAP
---------------------

This map controls, how long injectors are open (how much gasoline enters in the combustion chamber).

http://www.wolf66.slyip.com/Injection.jpg


This map has 16x16 fields. There are 16 RPM breakpoints and 16 air density breakpoints.

COLUMNS are RPM breakpoints. Address is at hex 7000-701F. In order to calculate one breakpoint,
you have to sum two 8 bit values and divide the number 1875000 with sum to get RPM value:

1. breakpoint:

address hex 7000: value 1 hex = 1 dec *256 = 256
address hex 7001: value 20 hex = 32 dec

256+32=288 1875000/288 = 6510 RPM

16. breakpoint:

address hex 701E: value 9 hex = 9 dec *256 =2304
address hex 701F: value 83 hex = 131 dec

2304+131=2435 1875000/2435 = 770 RPM


ROWS are air density breakpoints (absolute pressure) in bars. Address is at hex 7020-703F.
In order to calculate one breakpoint you have to sum two 8 bit values and divide them with 1032
to get the air density (absolute pressure) in bars:

1. breakpoint:

address hex 7020: value 0 hex = 0 dec *256 =0
address hex 7021: value CC hex = 204 dec

0+204= 204/1032=0.2 bar (-0.8 bar vacuum)

16. breakpoint:
address hex 703E: value 8 hex = 8 dec *256 =2048
address hex 703F: value 77 hex = 119 dec

2048+119= 2167/1032 =2.1 bar


Now at address hex 7040 follow 256 values for injection time (for every RPM breakpoint
and every airdensity point). These values are only 8 bit. To get the injector
opening duration in miliseconds, you have to make the following calculation :

(dec value*0.064)+1


2. IGNITION MAP
-------------------

This map controls the ignition advance.

http://www.wolf66.slyip.com/Ignition.jpg

This map has 16x10 fields. There are 16 RPM breakpoints and 10 airdensity breakpoints.

COLUMNS are RPM breakpoints. Address is at hex 7230-724F. Calculation
is the same as with injection map RPM breakpoints.


ROWS are air density breakpoints (absolute pressure) in bars. Address is at hex 7250-7263.
The calculation is the same as with injection map airedensity breakpoints.


At address hex 7270 follow ignition advance values. These values are 8 bit.
To get the ignition advance in degrees BTDC (before piston top dead center).
To get the ignition advance in degress you have to make the following calculation:

dec value*0.25


3. TURBO PRESSURE MAP
-------------------------

This map controls the turbo pressure. This is achieved via duty cycle
of opening the overboost (pierburg) valve.

http://www.moj-album.com/slike/5884310/GbBA1UzPI0y8inTV.jpg

This map has 16x4 fields. There are 16 RPM breakpoints and
4 breakpoints for TPS (throttle position sensor) opening angle in degrees.

COLUMNS are RPM breakpoints. Addres is at hex 75A0-75BF. Calculation is the same
as with injection map RPM breakpoints.


ROWS are breakpoints for TPS opening angle in degrees (how much you push the throttle).
Address is at hex 75C0-75C7. There are two different calculations:

for angles<30 degrees: (dec value*0.1848)-1.41

for angles>30 degrees: (dec value*0.7058)-90

1. breakpoint

address hex 75C0: value 0 hex = 0 dec
address hex 75C1: value A8 hex = 168 dec

0+168= 168*0.1848= 31.05-1.41= 29.64 degrees


4. breakpoint

address hex 75C6: value 0 hex = 0 dec
address hex 75C7: value E0 hex = 224 dec

0+224= 224*0.7058= 158.10-90= 68.1 degrees



At address hex 75C8 follow the duty cycle values. These values are 8 bit.
To get the duty cycle values in %, you have to make the following calculation:

((dec value*100)/256)*2


Max value for this map is 128 and not 8 bit max value of 256, as (128*100)/256)*2= 100%,
so the value of dec 128 means the 100% duty cycle or 100% opening of the overboost valve
which means the highest turbo pressure. But as the turbo pressure build up is dependant
of turbo charger type, wastegate actuator stiffness and RPMs, there is no logical calculation
for altering the values to get the desired turbo pressure. You have to try different values
and make test runs.


4. TURBO PRESSURE LIMITER
----------------------------

This map controls max turbo pressure which is allowed before ECU cuts the ignition.

http://www.moj-album.com/slike/5884310/_OEn2YX2AnCP213n.jpg


This map is 16x2 fields. There are 16 RPM breakpoints. This map shares the same RPM breakpoints
with TURBO PRESSURE map.

COLUMNS are RPM breakpoints. Calculation is the same as with injection map RPM breakpoints.

There are 2 ROWS. Second row is the max pressure limit. When this pressure is reached,
ECU will cut the ignition. First row is max pressure set. When ECU cuts the ignition due to
reached max pressure, it will start working again, when the set value is reached.


At address hex 7650 follow the pressure limit and pressure set values. These values are 8 bit.
To get the pressure limit and pressure set values in bars you have to divide dec value with 170.



5. WOT (wide open throttle) INJECTION ENRICHMENT MAP
------------------------------------------------------

This map controls the fuel enrichment at WOT (wide open throttle).


http://www.moj-album.com/slike/5884310/b26SGE7suTuQtt2h.jpg



This map is 16x1 field. There are 16 RPM breakpoints. This map shares the same RPM breakpoints
with IGNITION map.

COLUMNS are RPM breakpoints.

There is one ROW. It represents the factor which is multiplied with injection time at WOT.

At address hex 71D0-71DF follow the fuel enrichment factor values. These are 8 bit values.
In order to get the factor value, you have to divide dec value with 128.


Example:

address hex 71DA (11th value - 3200 RPM breakpoint): value 9D hex= 157 dec

157/128= 1.23

So at WOT at 3200 RPMs (here the turbo pressure starts to raise rapidly), there
must be highest fuel enrichment at full throttle. ECU multiply the value
from injection map (selected accordingly to RPM and pressure) with factor 1.23.

This means 23% enrichment at WOT.


6. INJECTION TIMING MAP
--------------------------

This map controls the injection timing (at what degree of turn of the crankshaft
injectors start to open)


http://www.moj-album.com/slike/5884310/Ng5ULCPFUmfVr5D6.jpg


This map is 16x1 field. There are 16 RPM breakpoints. This map shares the same RPM breakpoints
with IGNITION map.

COLUMNS are RPM breakpoints.

There is one ROW. It represents the angle of the crankshaft where injectors start to open.

At address hex 7200-720F follow angle values. These are 8 bit values. In order to get
the angle values in degrees, you have to make the following calculation:

450+90*(128-dec value)/32




7. RPM LIMITER MAP
----------------------

This map controls the rev limiter.


http://www.moj-album.com/slike/5884310/AS_vhn5Ue2g5OyxI.jpg


There are two values. At first value ECU cuts the ignition and at second
start to work again. These are 16 bit values. You must divide 1875000 with dec value
to get the RPM.

First value is at address hex 7497-7498
Second value is at address hex 7499-749A

Address hex 7497: value hex 1= dec 1*256 =256
Address hex 7498: value hex 14= dec 20

256+20= 276 1875000/276= 6793 RPM


Example to raise RPM limit to 7500 RPM:

1875000/7500= 250

250/256= 0 dec = 0 hex
remains 250 dec = FA hex

You have to alter the value at address hex 7497 to 0
and value at hex 7498 to FA.

You have to alter the second value accordingly (for example to 7300 RPM)



------------------------------------------------------------------



If you want to make the changes and raise the power safely, you have to
test the new chip with wideband lambda and some sort of knock sensing.
I use LM-1 from Innovative motorsports. I'm also logging all
significant sensors (TPS, knock, RPM, boost, ATS). With that
in mind you can raise the power of individual car well beyond the power
of "of the shelf" chips, as every engine is unique in its own way and
you can make the chip which is best for particular engine.

Wolf66, thanks for going to all that effort. Can you please either post a new copy the first two map pictures that have the "moj-album" logo superimposed on them - or email me a clean copy of them at jim@nielsen.org. I have a couple of other questions if you have time.

1. How did you come by the information in the tables, and how to work with them.?

2, what equipment do I need to program my own eproms of the style that the Q4 has?

3. what are the eproms that the q4 uses called? Model number etc.

4. are you testing with the LM-1 on the road, a racetrack, or on a dyno/rolling road?

Thanks, jimnielsen.

Wolf66
17-06-07, 09:23
I posted new pictures without watermark.


1.Values in tables are OEM chip values. In order to change them, you have
to have some tuning program or alter the values in hex editor.


2., 3. Q4 ECU uses 256 kbit eprom, so you can use
any DIL 28 pin 256 kbit eprom (27C256). You need Eprom programmator, whic supports this kind of eproms.


4. I use LM-1 on the road, as i have it permanenetly connected in my car.
I can record 45 minutes of data, download it to PC. Then i analyse this data
and make changes. It is better to record data on the road than on rolling road, espeacially with turbo cars,
because intake air temperature is higher on the rolling road, so conditions are not the same as on the road and
they are significant for proper AFR and ignition advance tuning.

17-06-07, 09:51
Thanks for updating the picture files! I was planning on using a basic hex editor to make changes - is there anything fancier or easier that you could recommend?

Thanks. Jimnielsen.

Thanks Wolf.
This topic should be a sticky and you named "honour member". Your sharing attitude makes a pleasure of being part of this forum.

A couple of questions now:

- What soft are you using to convert HEX to that friendly interface?

- How are you logging knock? OEM?? Filters?

- IAW has an Injection timing map? Isn't necessary to modify it if aggressive cams are used?

Thanks again and keep in mind that if you came to Argentina, the beers are on me.

Wolf66
18-06-07, 07:50
Thank you, Juan.

I'm using Tunerpro software.


http://tunerpro.markmansur.com/


I am logging additional knock sensor, but it is not 100% correct at high RPM,
because the drivetrain noise triggers it on some occasion. You need special
headphones for reliable knock sensing.

I didn't change injection timing for my Colombo&Bariani street max cams.
If realy aggressive cams are used, then it is necessary to change the
injection timing for optimal tuning.

Thanks a lot share hex adress with us .

I have some hex adress too ,but I dont know well what is it ?
for example , knock sensing adress ?

How learn it ?
How learn your hex adress ? and calculate ? Someone help you ?

What is your second knock sensor type ? oem or bosch ?

**** and people ,
changed eprom adress is critical ,
please dont play it ,
if you have NOT egt ,wideband afr ,knock sens ,forged piston and strong head gasket on your Q4 !
you can easly crack your engine .

Wolf have all this and wolf get power .

Well we could start with a directory for standard/modified q4 bins, .xdf files (tunerpro descriptions) and some of the info Wolf66 kindly has provided. I will keep you informed with all the work I will be doing, right after I receive my romulator.

jimnielsen
01-01-08, 01:58
Thats a great idea! I am getting a romulator as well.. What brand / where are you going to obtain it from / cost? Also we need a copy of the data on the EPROM that we KNOW is correct. I pulled the lid off the ECU yesterday to see what version of the software was inside - its 101.04 as you can see from the picture. I am going to get a EPROM burner so that I can make a copy of it.

Steve send me your e-mail and I'll send you back both the xdf file, to be used with the '101.04' file, and also the '101.03' file {1st Q4 serie, 190 bhp} and the '101.05 IMMO' for the late widebody serie.
By the way,
101.03 file goes with IAW type 4W6/P8P9U-EF
101.04 file goes with IAW type 4W6/P8P94-GA
and
101.05 IMMO, goes with IAW type 4W6/P8.

I've a problem with the chip I have driven for 1 year without any problems after changing the exaust, from standart to 70mm with out cat, driving with around 30001/min then WOT, the ingnition stalls engine at full boost, with original exaust no problem, at higher rpm it is also ok, I think this is due less backpressure and therefor very quick Boost raise, have anybody some experience like that,

"Wolf66", many thanks for your explainantion of the map translation. I think I have tried to figure out the air denisty breakpoints for at least 5 years without finding the exact answer.

However I have my doubts about the turbo duty cycle translation. Based on the code published once one HF Alex (Alex Segala) website I made the conclusion that 100% duty cycle did not correspond to value 128. Like Alex I have gone higher and even though I can't prove it to be correect I haven't found any reasons against it.

Then I think of the set- and cut-boost-pressure vectors. I consider 255 to correspond to 250 kPa absolute pressure, you say 1,5 bar (150 kPa) boost preesure and the Coupe 16 V definition file at Prograle say 1,55 bar boost (x/100-1). Se result is mor or less the same, but the last interpretation gives the possibility to set an infinite boost limit since the sensor can only read 250 kPa absolute pressure. The Cosworth's ECU's are made like that.

Any comment?

If you real want to program you car you need imao a Ostrich or product like that.
I have one, and it is 1000 times more easy to be able to make the change on the fly without burn a new chip every time..

Maybee it is kind of overkill if everyone buy one, so maybe some of you could share one with eachother..

29-11-10, 16:31
thanks, so, for 101.05 IMMO is it the same .xdf file? i don't think so, because i have the same prices to all fields ex. injection, all rpm is 28, the throttle is 63.50 and all rows and columns are 17,32, so i guess 101.05 IMMO must have another *.xdf file. Please someone respond!

Send them through to the usual address and I'll get them up on the site.

Are the files on the site corrupted then? Worth taking them down?

I think that happened to me too some time ago between tunerpro versions 4 and 5.

I had to do some manual adustments of the .xdf files, don't remember what , so you could first test and older tunerpro to make sure

Why you'd want to disconnect knock sensor?

Hi to all
I'm trying to understand some issues mapping with tunerpro the P8 4WF ecu of Fiat Coupe, and maybe your feedback with the Q4 ecu could help.

With the xdf of your site, I obtain for 155 Q4 turbo duty cycle the following table.
Is that correct? Especially those 100.0 values at low rpms...

When you are on the road, does the yellow box that indicates the exact point where the ecu is reading works good in this table?

Thank you!

I think they are 100.0 because you need full boost at low rpm, that's why you want your WG closed.
155 q4 has an overboost at low rpm, 1.1 bar (0.8 bar w/o overboost).

As for the yellow dot, no idea. I assume you're using Ostrich with live mapping, but never done that.
