Target Car:

Bmw 325 (currently Motronic 1.3)

2.5L 6cyl I6 engine

Aims

Sequential sparking
300 dergee camshaft

Problem - solved by uploading a good config

In MegaTune everyting works expect the Spark angle.
- do you have an LCD ? does it show roughly the same ?
  - We have LCD. Yes we see the same. Spark angle show -01.
  - We put firmware v0.36 nad later 0.58. but still the same problem. The Megatune is 2,25 version. (everytime we run Megatune in the begining show "this wrong version.... Can we terminate the program?"

the spark angle changes just now, getting a 64 degree offset (so display range changes to -64..+64 degree) this is a one-liner in vemsv3.ini but indeed an incompatibility between most recent and older MegaTune / firmware (direction: new MegaTune shows -55 degrees with an old firmware, when the real ignadv is 9 degrees)

See IssueReports on what information is needed to be able to help.

MegaTune version
firmware version
config and tables
- mcd dump
  - most importantly: ign_balance
- mct

We filled the Spark table but th Spark angle indicator show -1,75 degree instead of ... degrees at RPM= and MAP= ...

WE SOLVED the problem with upload a good config and table.

Air and Coolant Temp Characteristics

Now the following question.

How I can make a Air tempereture characteristic.

I used EasyTherm program to make a *.inc file
- we use hexpatch (found on EasyTherm page) to upload a previously generated tables (gets very close; start with 2252_256, since the most common sensors are appr around that)
How can I convert *.inc file to *.hex file?
- this is in fact a good idea. propertherm.pl has the code, but we should release a small win (and linux) program (written in C) that does this (either from .inc or from the 2 main parameters "2252,256") : this way the gourmans can tune without much wizardry

We have 6 injectors in the bmw. 3 injector connected in paralell.

Can I do the same in Vems output, I mean Is it possible to swith 3 injetors with one output (igbt)?

Succesfully day for the national.

We crank our engine and its starts for first time.

It was great pleasure for us.

We are really happy!

And I have a Birthday today! :)

PROBLEMS:

The Ego Correction does not work. It switching On and OFF 1 second periodically.

- The lean Limit: 15%

- Rich limit: 2%

- Step 1%

- Speed change: 50

we tried to change the parameters but it is doing the same.

What could be the problem?

we have dual solenoid motor for Idle.

No Idle control at all.

IAC wiring

EC36-pin6 to IAC close pin
EC36-pin17 to IAC open pin

Can you measure

changes in measured DC value ?
freq of original control (that works) ?
take log with megatune (so we see that iac.position changes). You can also check on LCD as well (mlp03 or so), but capture a MegaTune log.

also, your iac_max_steps=32 limits iac actuator range greatly, since you have a pwm controlled iac, use iac_max_steps=FF (or 255 dec)
