Summary of change:
IAC: Bosch 2-wire 2.6 ohm 4.6 A (marad a gyári hején) * flyback (védö) diodát az indukcioval szemben beraktam (ELLENORIZNI!) ** katód (csik) a szelep +12V pontjára ** anód az ECU output-ra (ahova az ECU kapcsolja a GND-t) **ECM36pin6 (inj-g, mask=64) idle air configuration starting point: MembersPage/MarcellGal/PowerAndTraction * iac_sol_channel=60 * assuming h[0]=01 02 04 08 10 20 '''40''' 80 ---- Az Manmdi27 tel jó az alapjárat (RPM=....?? CLT=... C ??) ami dec35=15,29% Berakom a txt-ket. http://www.vems.hu/files/GolfGtiLpg/mcd10_26-saved.txt http://www.vems.hu/files/GolfGtiLpg/mct10_26-saved.txt Sajna nem vagyok benne biztos hogy hova kell beirni. ---- '''Idle at cold and warm''' The '''iac CLT-dependent PWM reference positions''' are very important for the idle air control. If these are wrong, idle will be too high (or otherwise bad) at certain points, even if it's tuned at other points. <code> iac_ref_pos[0]=BF iac_ref_pos[1]=BA iac_ref_pos[2]=AD iac_ref_pos[3]=A8 iac_ref_pos[4]=A1 iac_ref_pos[5]=91 iac_ref_pos[6]=82 iac_ref_pos[7]=7A iac_ref_pos[8]=75 iac_ref_pos[9]=73 </code> Beware that the Bosch iac actually opens up a bit below appr 25% duty. (you can test by removing the iac connector). So the minimum air is maintained by appr 25% duty, consider this during iac tuning. Though the iac PWM reference for (CLT > 71C) is 45%, depending on iac integral decrease limit and other factors it might reach so low duty (25%), that the solenoid actually starts to open up when the ECU decreases duty to close it further => positive feedback, in this case idle RPM will raise.
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
