FIRST OF ALL READ PSINUSE'S STICKY to make sure that opensource is what you want and know the issues of doing it wrong

Tuning FAQ - RomRaider - http://www.romraider.com/Documentation/TuningFAQ



needed equipment/ tools:
laptop (with full charge)
tactrix cable (for your make and model)
Ecuflash software (Open Source ECU ROMS) http://www.osecuroms.org/
Enginuity software(RomRaider - Open Source ECU Tools | RomRaider / Rom Raider) http://www.romraider.com/
[before doing any of the following steps turn your key forward but not on make sure your battery is charged ( if you have a turbo timer shut it OFF)

step 1: connect your tactrix cable to your laptops usb port
step 2: connect your tactrix cable to your diagnostic port
step 3: connect green wires this puts your car in diagnostic mode( you will hear your fans cycle) they are under the dash closest to the drivers door
step 4: open ecuflash
step 5: read your ecu's stock map and save it to a SD card,flash drive, or to your pc
step 6: open your desired map
step 7: test write to ecu to make sure of connectivity or errors
step 8: then if everything is ok write(flash) the desired map to your cars ecu
step 9: read your ecu again and compare your map to the map you flashed(you can use enginuity for this step if desired)
step 10: disconnect the green wires
step 11: start your car and take it for a ride to make sure it runs properly( no sputtering or knock) obvious signs it is not running correctly
step 12: log your car using enginuity
LOG THE FOLLOWING

Air/Fuel Correction #1 (%)
AF Learning #1 (Current)* (%)
Coolant Temperature (F)
Engine Load* (g/rev)
Engine Speed (rpm)
Feedback Knock Correction* (degrees)
Fine Learning Knock Correction* (degrees)
IAM* (multiplier)
Ignition Timing (degrees)
Injector Duty Cycle (%)
Intake Air Temperature (F)
Manifold Rel. Pressure (Corrected) (psi)
Mass Air Flow (g/s)
Throttle Opening Angle (%)
Vehicle Speed (mph)

ENJOY THE NEW POWER AND USE IT SAFELY

Indemni lumea la prostii

[andea79]

Stiu ca e vechi topicul, dar ca sa nu deschid altul pe acelasi subiect: cine a mai experimentat/invatat chestii interesante pe open source ? In cluj suntem vreo 2 cel putin care mai citim/experimentam asa usor dar ar fi interesant de povestit si cu altii ...

[malakay]

si pe mine ma mananca rau ... sa imi cumpar  un tatrix cable ... sau un acces port de la cobb dar nu stiu daca o sa mearga acces portu pe edm sau jdm !

[STI]

acces portu nu merge, acum pe generatiile noi poate au schimbat ceva dar in rest doar usdm pentru acces port

[andea79]

acces port nu merge intradevar, in schimb tactrix/romraider/ecuflash ... fara probleme
eu mai "shurubaresc" una / alta asa lejer pe ecu map-ul meu, cand sunt foarte odihnit si cu mult timp liber de logat/modificat/logat/logat ....

[daniel.gugu]

ceva noutati pe aici?
andea79 poti face publice logarile/modificarile/logarile/logarile ?

[andea79]

Pai eu pot "publica" loguri ... desi asa fara nici un scop anume nu stiu cat de folositoare/de inteles ar fi.
Ideea e ca pe logger sunt cativa zeci de parametri care pot fi monitorizati si in functie de scopul operatiunii de logare (ca se urmareste daca se atinge target boost-ul, ca se urmareste timingul, ca se urmareste in ce situatii/daca apare knock...  sau altceva ...) se selecteaza cativa parametrii relevanti si log-ul normal va contine aceste informatii.
