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 [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).
- if not, measure voltage on mot55/pin41
ECU serial number is : v3/10581 again given to you on my email as the heading of my email on the 19/5/2017. You obviously DID NOT CHECK hence now accusing me of not having enough order in my requests.
So now that you know what my ECU serial number answer me this simple question rather than wasting time explaining things i do not understand (nor a large majority of electricians who do not deal with VEMS directly): Will you require my ECU to upgrade hardware or can yo do this with external parts and instructions?
It is you who are supposed to say to your customer: Yes it can be done and i can do it OR you as a customer has to do it, here are the parts. etc. DO you or DO YOU NOT have a service to provide possible upgrades as you implement new things to your product? Do you sell these things only to tuner providers and let them do the job?
Tell us exactly what you can or cannot offer, so that i can know if i will ever bother asking things from you, or simply pay someone who knows how to speak to people.
