it works now thank you Admin.
-
But its not, Car does not start. I have a fuel pressure gauge and it generates no pressure this way.
If I use the OEM Relay i must route a ground and aux 4 together in series with a ground for it to work.
OEM way has it routed this way with OEM ECU in order to work.
If i route the Atom ECU the same way as the diagram above it also enables the Fuel Pressure with the OEM relay.

Aux test is set to ON
85 aux 4 shows 0v
86 ign switch 12v
while cranking it still shows 0v on aux 4 side
Settings for Fuel Pump

i am using atomX
aux 4 to 85
ign switch 86
12v (20A Fuse) 30
fuel pump 87
When I use OEM relay
AUX 4 to Y connection one to ground and the other to relay(OEM) works with no problem
-
so it works when i have 85 sent to ground. this way its running only of ign switch and not via ECU switch

Hi admin I was not successful in powering up the Fuel Pump. I made wiring exactly as describe. I know each line is correct because its the same Ign Switch power i am using for my main relay. If I bypass the fuel pump relay with straight power it comes on.

thank you

Hi Admin,
I want to stop using the OEM relay used for the fuel pump as its giving me problem. Can I get an idea how it should be hooked up to create an aftermarket relay.
OEM way i have a ground connected to ECU output before connecting to COR(Fuel Pump Relay)

got it thanks!
-
so 85 would go to my ECU and 86 would be from ignition switch? 30 battery and 87 to fan

Hi I have a g4 atom and I am setting up aux 4 for electric fan but even though it worked before by 12v trigger. I am not having succes
Can I use a low level trigger relay to enable the 12v fan? I was thinking of using this:
YWBL-WH Relay Module One Way 30A Optocoupler Isolation Relay Module High Power Relay High/Low Level Trigger YYG-2(5VDC) https://www.amazon.com/dp/B07TWH7DZ1/ref=cm_sw_r_apan_glt_i_8VN587K55A5D3EVN3FA9?_encoding=UTF8&psc=1
Not sure what to Power on the board to test without an arduino since signal is coming from the ECU
-
its always the simple things, turns out i didnt assign each sensor to the correct configuration.
Thanks admin for the assistance
-
No map sensor installed as mentioned initially. tuner mentioned it shouldn't be problem
I tried the TPS and i see the voltage change when I move the throttle cable from the live data.
I will test the ECT and test the IAT and see if the readings are coming in the live data.

How do I record a pc log.
The car only cranked but no start whatsoever.
-
No luck after uploading new file. Same results
here is another triggerscope and ecu log

here are the logs, is trigger 2 not working? I didn't see a signal under the capture for it?
Added
trigerscope log
ecu log during cranking(2 logs)

Hi after I connected the harness I am able to to test all my sensors thru the ecu to see that they work except vvti. However my car cranks but it won't start. Is there anything I can do to see what might be causing the car not to start. I Have a gauge for the fuel pump and I see pressure.
I was not able to activate vvti and I am not sure if that would be the cause to why the car won't start. Also how do I test trigger 1 and 2? When I check voltage I see around 3.5 volts I think I can't recall the value exact haha
Using the same file u provided only thing I adjust was AUX 1-4
1. VVTI
2.Electric fan
3. Tacho since ita digital.
4 fuel pump
Any advice to trouble shoot would be greatly appreciated

Hi guys,
Need a Base map for Blacktop 4age 20v with 1nz COP, TPS, no MAP sensor. Atom ECU
Admin could u move this to G4x Side?
Aftermaket Fuel Pump Relay
in G4x
Posted
thank you but unfortunately I don't know why it wont work that way. I have to connect a ground in between 85 and aux 4 for it to prime the fuel pump. nonetheless i wont touch as it works this way with a an aftermarket relay
