    Mitsubishi RVR - Idle hunts & No aircon?

    Should I try swapping Pins 45 and 11? Maybe the resistor on that pin is not happy?

    Mitsubishi RVR - Idle hunts & No aircon?

    I did find this document: http://indy.pp.ru/GDI/Docs/SPACE_RUNNER_WAGON_91_ENG/wiring/92MY_N10_N40/PHDE9214-A-B_SPACE-RUNNER_SPACE-WAGON_92_ELECTRICAL_WIRING.pdf Although it looks to be for the earlier Space Runner wagons as the document was created in 1993 and doesn't list the N23W. Page 168 Looks to be where some diagrams start for the RHD 4g63 Models. It looks to be for a N/A 4g63 SOHC engine though too but could be of some help? -------- Oh actually, what about this? https://www.dropbox.com/sh/8mvxbuy0pajca2i/AADVTKTBc8hEH_6VaU7A1pZwa There is a folder in there named "climate control" with some diagrams?

    Ahh damn it seems to be impossible to find a wiring diagram for the N23W RVR let alone the evo 3 I've been looking for a while haha. Maybe some of the DSM stuff could be worth a check.

    Ahhh righto, thanks for explaining that Adam, makes sense I just tested Pin 11 and no voltage at all with or without A/C - Stays at 0v I noticed my Pin 11 wire is green, whereas the Evo3 pinout chart I was looking at mentioned a Green/White wire. Maybe the RVR does not use this? Would this be an idea in that case to move Pin 45 to Pin 11 and use DI5 as my A/C Request? That way the Pull down resistor should hopefully bring the voltage down when I turn the climate control off? I just noticed too If I leave Digital Input 5 Off and just Use DI1 (Pullup: Off, On Level: High), The AC requests and clutch status etc all flick to On (and don't turn off) but I don't actually get cold air? If I leave DI1 as a GP Input instead of the AC Request, I do get cold air etc, it just obviously doesn't register as an AC request, so the car stalls under the load.

    Alrighty, so I grabbed the connector in between the ECU and the climate control unit and unplugged this (Pictured below) It looks to have 2 of the same Green/Yellow wires that Pin 45 uses. Did a quick test on this and found it reads 13.5v~ through both of these pins coming from the climate control unit which switch to 0v when turning AC off (All with the car running) So this side looks good? Going to try the ECU side now Ok, so it looks to be the ECU? I turned the car on and left it running. Unplugged this connector and turned the AC on Climate control side shows 13.5v and switches to 0 when I turn it all off. ECU side showed 0.2~v which I assume is all good. Plugged it back in with the car running and AC on - Found the 13v went through to the ECU side of the plug - All good Turned AC Off and saw the 9v again on both sides of the plug. Unplugged this and tested the ECU side - Still 9v Climate Control side is on 0

    Car has been out of action for a while but I'm back to try and fix this up. So voltage between pins 71 and 45 reads 0v when the car is off. With the car on, but not running - 0.2v (should be all good?) All AC request statuses are off in PCLink here With the car On+Running - 0.2-0.21v Turning AC on results in all requests becoming active and volts between pins rises to the 12v - All good When I turn the AC back off though - The voltage drops to 9.93v? and that's where the AC requests stay active while the Climate Control unit is actually off Any ideas what's going on there? Pullup Resistor: Off - Results in 13.5v through the Pins But still only drops to the 9.~v

    The climate control unit does have a "ECO" mode from factory, I wonder if that might even be related also? I believe the eco mode cycles the clutch less frequently than the regular mode. The grounding could be a thing, so I'll give that a go tomorrow as well and report back

    Mitsubishi RVR - Idle hunts & No aircon?

    Ahh of course, didn't even think of looking at that I had a quick play with that set to low and managed to get the AC on, with the clutch and the Idle up also working but couldn't get it to turn off. I'll be more specific when my Laptop doesn't run out of charge and I'm back home but I'm pretty sure I tried most of the combinations available with On Levels and Pullup Resistor while also turning Digital Input 1 Off with 5 On and vice versa. It seems like DI5 is the input that actually turns the Clutch on with the AC button on the Climate Control unit. The installation manual does list DI5 as being the A/C switch and DI1 as the A/C "Request". Could that be something to do with this? Both Inputs were set to A/C Request out of the box and I didn't see an option to change it to a "Switch" (Assumed this might just be the same thing anyway)

    Oh my bad, I turned that off while I was troubleshooting Here is the Map and log with Clutch control back on. When I turn the AC on, the switch activates and it says it's engaging the clutch, but I don't get cold air. all the switches also stay on when I turn the AC back off. I'm wondering if that's what the second AC request input is for? RVRmap.pclr Log 2018-08-7 2;09;21 pm.llg

    Thanks Adam, here is the log: Turn on - AC On - AC Off - Engine Fan.llg Edit: and the Map: RVRmap.pclr

    Alrighty, so with the climate control off: - DI5 Ac Request: ACTIVE - DI1 Ac Request: OFF If I turn the fans on, everything stays where it is If i turn the AC on, DI1 becomes active, DI5 stays always on This is with everything set to On level: Low and Pullup: Off If I turn DI5 Off and leave the DI1 AC request to control the AC, When I turn the AC on, the clutch value stays OFF and does not use the AC Idle step table (Resulting in lower revs but working AC)

    Thanks Adam. I got into the open loop idle control after doing some more logs and adjusting my fuel table towards the targets That now seems to be working fairly well at keeping at my 850rpm target. The engine fan still drops it a tad but recovers a second or 2 after which seems better. The aircon has me stumped though. I have Digital Input 1 & 5 which are both A/C requests. By changing DI1 to "on Level" high, I was able to get the AC request to become active when using my climate control, which lowered the revs (Ignoring the A/C step table) and started pumping cold air. If I ALSO change DI5 to the same "on Level: High" the Clutch physically seems to disengage, the aircon looses it's cool, but the ECUs Clutch and A/C status all comes on which increases my revs using the A/C step table. And then If i actually turn my climate control completely off, the ECU statuses all stay on? I have no idea what is going on there haha. I tried multiple different combinations of leaving only 1 of the 2 digital inputs on and playing around with the Pullup resistor settings also. It seems to either give me: - Low revs (No step adjustment) + cool A/C that I can turn on/off - Step adjusted Revs but no cool air that I can turn on/off - Cool air, A/C stepped revs that I can't turn off, even if i turn the car off and leave the ignition on. Any ideas here? This bit has me stumped I just have the clutch control turned off for now

    Mitsubishi RVR - Idle hunts & No aircon?

    Thanks Adam. I adjusted the Fan step down which looks to have helped out but still seems to be a little sketchy. I also found I had to switch the Aux 2 - AC Clutch polarity to High to get that going Now just figuring out the idle adjustments for this which are confusing me a bit. I have attached a log that shows my warm start where the idle dips for a couple of seconds and then the result of me turning the aircon on. I can't seem to stop it from dropping revs withe the AC step adjustments? Not exactly sure what needs to be done there. I also attached both logs for the Crank on & AC as well as the new Engine fan idle stalling on AC.llg dropping on engine fan.llg

    Mitsubishi RVR - Idle hunts & No aircon?

    Hey guys, I got the evo 3 CAS installed and started up the car to adjust base timing. Looking all good (Y) Not sure what I have done, but now when trying to start the car, it hunts around all over the place and eventually stalls. I also found last night (While it was all working) The aircon doesn't kick on? i'm wondering if the Evo pinout is slightly different to the RVR in this regard. i'll be doing some more research on that end of things to try and find out why that isn't happening. Unsure if I've captured everything I need, but log file attached. idle drops.llg

    Mitsubishi RVR - EvoLink G4+ Trigger Issue?

    Swapped in a cam/crank sensor from an evo 3 today and made up a loom to match up with the RVRs cam+crank sensor plugs. Put it all back together and started perfectly using the Evo 1-6 Trigger mode :) No errors whatsoever. Thanks for the help guys!
