So should just remove the toggle control ECU relay . And make a main switch control supply for ECU and FAN relay terminal 85 along with FAN relay rerminal 30 instead? With all those components fused as well.

Greetings. I have running into some wiring issue I believe it causes back feeding my link atom X thru a AUX 4 fan relay control. The car now have main switch goes from battery fuse directly to the relay box I notice that my ECU is not switching off with a toggle switch when my FAN relay is connected to AUX 4 which I setup as FAN relay control PIN. (Blue led light on whenever the relay plugged in with main switch is on) So I have attach a supply wiring diagram of what I have in the car. Maybe I should remove the toggle switch controlled ECU relay and let Main switch do the ECU and FAN supply control. Notes: the aux4 work fine under pc link test.

i see. really thank you for the explaination

Sorry . My mistake for creating the misunderstanding. I have reupload again with clearer path of my 85 terminals. This one is the one mostly everyone is taking about right?

Greetings, so after i read through the samples for Aux relay switching, i made a mock up wiring diagram for my fan relay. mind to have a look? if it was fine to run a relay control circuit without a fuse. Load circuit is fused . the sample diagram attached below is how it will be wired up .

So . i have setup the DI2 as below . the question on calibration values = 260. what is that means? Km/h?

Greetings, I m a 4age 20v bone stock running on link g4x atom. i got the VSS located on the transaxle wired into links ecu DI 2 . just check on it, VSS is in 3 pin design and run a 12v power supply. assuming it to generate a square wave signal input to my Link ecu having no clue on how to setup DI for my vss. any clue for the setup the DI. p/s there's a wiring diagram i built attached to this thread. any help would be great wiring.pdf

Very thank you for all the advices. turned the gp rpm limit off and the car start just fine. right. it will be a learning scope for me in future

Greetings . i am running an atom x for 4age 20v stock injectors stock distributor and igniter. with No ISCV and VVT. I found that coil is not giving out spark as i crank the engine. suspect injector no opening as well based on the log i found it out its not giving spark when i have all 4 cable and spark plug remove and placed on the valve cover to check spark I did injector test on all 4 injector with fuel pump run. I can see clear fuel spraying. Did a coil test as well. with 2 coil and igniter unit from running 4age. I do notice a GP rpm limit #1 code was stored. Not sure what is that and why. check all the 12v on coil, igniter and injector with test pen as well. seem to be fine. checked distributor AC voltage signal as well. 0.5v at 500rpm for 24 tooth and 0.3v max pulse at 500rpm for home trigger or i have missed out anything to active the injectors and coil? I can see the inj 1-4 and ign 1 is active during the crank . but 0 duty cycle and dwell in the log. pulled a trigger runtime list . trigger 1 and 2 goes green as i crank. i have upload a pclx , log file, trigger scope log and wiring diagram i have built. p/s FAN relay and VSS is not connected for now TriggerScopeLog.llgx PC Datalog - 2022-04-24 3;22;30 pm.llgx 4age20v.pclx wiring.pdf

Noted. thanks

Greeting, long story short, Is it possible to have trigger scope for atom X. if yes how can i get it displayed. what i can see for now is trigger arming voltages , nothing more many thanks.

i have made a correction for Temp sensor and MAP sensor. attached the result as attachment below it seems that the An temp sensor Error high have default setting of 0V. Now i put a 5V for the error high is that alright ?

Greetings, i have an issue regarding calibration of IAT, ECT and MAP sensor. As i connects the ECU to my laptop, i got this 2 code error code 46 and error code 43. i also noticed that the calibration table for IAT, ECT and MAP sensor was pre-selected for k20 temp sensor. Question is which calibration table should i select . note: i have tried TPS calibration , seem to be fine. Engine = 4age 20v, stock ECT, IAT, and stock MAP sensor. ECU = Link g4x atom ii. ECU harness was built from a 2.5m link g4 harness. all the sensor wire was install with the harness tags. attachment added, kindly refer Csheng4age20v.pclx

noted. thank a lot. thanks

Evening, i have a 4age 20v planned on running with stock distributor single coil, stock injectors, No VVT, no ISCV and bone stock everything AUX 4, FAN relay AUX 3, shift light Mind to share a base map for reference? i have attached a wiring diagram of my own wiring. please do correct me if i have made a mistake in the wiring part. link diagram.pdf
