The link ecu does show up in realdash. It just keeps saying connecting and i dont get a prompt saying "connected". No i havnt tried using my otg with any other device besides my old phone to transfer my data over. I did indeed powercycle the ecu after connecting.

Im trying to connect my link g4 pnp to realdash on my samsung s10+ and have set up ecu as per the instructions. Im trying to use the samsung usb to type c otg adaptor. Im just not able to connect. Am i missing something. I did setup the ecu the same as g4+ continous 12hz and 38400 baud rate. Is it different for my ecu?

Have checked the wiring loom pinouts etc from iscv to the ecu. serviceable. i rigged up my old iscv externally so i could visually confirm valve movement. it is indeed moving, therefore i can pretty confidently say that the iscv is alright. i cant find any vacuum leaks either and have checked base throttle plate position which is in the correct closed position. im all out of ideas i managed to set the base idle set screw on the throttle body and it got significantly better. the log is below. it now only fluctuates between 1600- 2200. it is still hitting over run fuel cut. evo hunting idle 7.llg

Oh and i just remembered. My bov is modulating open/closed while it has this hunting issue. I will try disconnecting bov and have the 10psi spring hold it down and see if it still hunts

On a side note adam. Since it was hunting prior to the isc stepper actually being switched on aux 5 -8. And things havnt changed. Logic is telling me there may actually be an air leak somewhere like you have suggeste.

ok. i just tried that one last map. no change really. I will be double checking the wiring in the morning to see if theres any issues there and will also go on the hunt for an air leak. evo hunting idle 6.pcl evo hunting idle 6.llg

I have replaced the iscv with another unit which had resistance measurements within limits. below is the log and map of the result. evo hunting idle 4.llg evo hunting idle 4.pcl

i gave it a go. its a lil better for the first few seconds but then goes back to normal. it was only fluctuating 400rpm then went back to the same as before evo hunting idle 3.pcl evo hunting idle 3.llg i have measured the resistances between the power pins and the other 4. all resistances are between 34 and 36 ohms. which according to the specs is a lil bit off. i believe the range is supposed to be 28-33 ohms. may have to look at either checking the idle stepper motor position just in case its some how changed. and if that fails try another iscv

thank you very much adam. noob question. how do i load that map?

evo hunting idle 2.llg evo hunting idle 2.pcl i gave it a go. i didnt see much difference. is this a sign of a faulty valve?

i should probably add i am currently using the existing tune on the ecu. is the base map a better starting point?

i think ive done this correctly. evo hunting idle.llg evo hunting idle.pcl would it be any help if i basically copy the numbers from the evo 4-8 base map? the numbers in the base map to what i currently have look miles apart?

hi there, I am just getting the car ready to get tuned after this lockdown. an issue i am currently having is on cold start the idle hunts from 2000rpm to about 3000rpm. The ecu was tuned on the previous owners car. Im assuming he wouldve been running the same idle control stepper as factory. I have already set the injector settings as per the injector manufacturers specifications. I am wondering if this an actual idle control issue because it still does the same even once its warmed up. or should i maybe pull the idle stepper motor off and clean it or something. Ultimately i would like to have the car at least idling nicely before i take it in for a tune. Can upload the idle control settings if that helps

"So you where getting fault code 14, but now you have turned off AN Volt 2, and connected the MAP to AN 6. Are you getting fault code 26 now? The onboard MAP sensor is normally on AN Volt 1 on the Evo4-8 plug-in - Are you not using the on-board sensor?" Correct. I was getting code 14. i suspected there may be a fault in my wiring so i switched to the AN V 6 which is off the expansion connector (using expansion connector +5V and gnd) to confirm if my wiring was the culprit. i then did receive code 26. I do not have an onboard map sensor, i am using an external Link 4 bar map sensor. "To diagnose, If you temporarily set the AN V 6 error low to 0.0V and error high to 5.0V, then it wont go into fault condition so you can then go to the runtimes screen analog tab, and see the actual voltage coming in to AN V6. If it is somewhere close to 0V then you have a wiring or sensor problem." I will try this tomorrow. I will also re pin MAP to AN V1 and see if that works. I didnt really think using other AN V input channels would make a difference. Runtime values suggest no issue with the 5v supply and i am also running an oil/fuel pressure sensors which are working as they should. I seriously hope the sensor is not faulty as it is brand new. kind regards

hi there guys. I have built another harness for my evo and everything works fine but im getting a code 14 AN Volt 2 below error low value. I understand that the MAP is at 0V/GND. I initially thought i made a mistake in the wiring so i connected the map sensor to the expansion connector to AN Volt 6. The issue still remains. this leads me to believe maybe the MAP sensor is faulty but it is brand new. I have looked at the fault settings and everything looks alright. error high = 4.95V error low is 0.05V and error value is 100Kpa. is there something i am over looking? kind regards
