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?"
- do you have an LCD ? does it show roughly the same ?
- 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
- mcd dump
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.
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:
1.
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?
2.
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)
We solved the problems!
NEVER SET THE ACCELERATION ENRICHMENT TO ZERO BECAUSE THIS SWITCHED OFF THE EGO CORRECTION!!!!!!!!
