IMPORTANT: enter the case-INsensitive alphabetic (no numbers) code AND WRITE SOME SHORT summary of changes (below) if you are saving changes. (not required for previewing changes). Wiki-spamming is not tolerated, will be removed, so it does NOT even show up in history. Spammers go away now.

Summary of change:
Subpage of MembersPage/VasilisP * Sibling of MembersPage/VasilisP/EvapOutput ---- '''AC => mot55/pin41 => mcp3208/... analog input => fw configured to raise idle''' This '''setup can increase the idle speed once AC clutch kicks in''' * good, '''only a protected mcp3208 analog input is needed''' for that * it is considered that after 2017-05-23, by default: mot55/pin41 is connected via 75k/(75k+100k) divider to mcp3208/ch3 (only when 1 or 0 EGT is requested: 2 EGT is very rare anyway for this inline-5 engine) ** 14.7*75/175 = 6.30V a bit too high, maybe series 68 k resistor with the onboard 100k: 75k/(75k+168k) would be more appropriate against potential voltage spikes ---- So that my idle doesn't drop or stall. Believe me i have messed around with idle IAC settings probably more than anyone else,and there are occasions where the idle still drops and stalls. So for that reason alone, i would like to make use of this feature which i believe to be very important for my car. Yes, understood. Makes sense ! ---- 2) I would like to have the option for the AC feature from firmware 1.2.38 '''Protected analog input needed''' to connect the '''12v signal from the air con compressor''' to be incorporated to the ecu in order to use the settings to control the idle. Please write everything you can about YOUR (actual) EC10 pinout in the EC10 section on MembersPage/VasilisP/EvapOutput ---- '''Analog input verification''' With 1kOhm resistor, see the bottom of [http://vems.hu/vt/help/v3/v3_analog_input_calibration.html VT help] * mcp3208/ch6 might be without protection (=not suitable for 12V) * but other mcp3208/ch (0,1 normally without pullup or 2,5 normally with pullup to +5V) might be suitable for easy connection to AC activation View gauges: '''analog inputs raw''' group. * '''Perhaps one of the analog inputs already show''' when AC clutch is activated ? ** if not, measure voltage on mot55/pin41 *** => if mot55/pin41 indicates AC, connect to a protected mcp3208 analog input (and configure and document accordingly).
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.
