Link Ecu G4x Honda Integra B18c6 don't Start engine.

Hi everyone!

I set-up my new g4x Link ECU with manual HC96X. Trigger I think are correctly and Ignitión set-up good too. Fuel Pump is disable to calibrate triggers but the timming light dont work. Is It posible to dont spark? Is it possble that if the trigger offset configuration is not correct there is no spark? add Capture set-up ignition and triggers now

The car is a Honda integra Euro B18c6 with OEM distributor and OEM triggers.

With Hondata S300 V3 runs Perfectly.

Thx!

You can see in the scope capture that there is a small voltage spike on trigger 2 being interpreted as a valid edge and this is resetting the tooth count. I suspect this could be either the trigger offset is a long way off so the spark is having to jump a long way from the rotor to the distributor post, or possibly a ground issue causing the spark return to pass through other circuits.

You could increase the trigger 2 arming threshold a little and the trigger 2 filter so this spike is ignored. Also try moving your trigger offset 15deg either way.

Hi,

With Adam corrections the engine starts, trigger 2 threshold 0.9 and sequence was good.

Now the engine makes a fairly loud humming noise, it seems to be coming from the distributor, what could it be?

Thanks for your comments

It could be that your distributor isn't "clocked" correctly, so that the rotor is inline with the spark plug at the timing you are using. If the spark has to jump a gap, you might hear this as a "buzz" or "humming" from the distributor. Now that the car is started and running, have you verified the trigger offset with a timing light?

Hi David, I verified the trigger offset and It's perfect and exactly with set-up on capture. Before I moved +-5º and test with timming light on idle.

The humming sound like a this, Link: Humming

And I have another question, at stable idle I touch the accelerator and the reaction is vague, it seems like it's drowning and it reacts within a second. If I keep it around 1200-1500 and hit the throttle at 2500 then it works fine. At the moment don't have idle control active and close loop is off. TB it's OEM cable. Add Capture Datalog for this point.

Thx for your help

Attach the actual log file, a screenshot is not useful. You can put inside a .zip folder or share via Google Drive or similar if the forum doesnt allow the file type.

Add Zip with Map and Datalog. For now I just started the engine.

It is difficult to give much advice related to fuel when there is no wideband connected, but my guess is the main cause of the stumble when opening the throttle is because your accel fuel cold correction is zeroed out, this means you will get zero accel fuel. The original values in the civic base map will likely be a better starting point, copy of those below.

Hello Adam@Link_ECU,

I have not yet been able to make a datalog, when I do the configuration I will upload the data. The only solution at the moment has been to raise the minimum idle rpm to 950. Looks good but whith Tip TB still lean. I have WB input directly AEM uego and configured in Cal Table 1.

I have good news, I solved the humming sound. It's from IACV PWM Frecuency control.

The default setting of the IACV by Link is 200Hz, this valve can even operate at 100-150Hz but this causes hum inside the intake. The correct setting to eliminate noise is 300Hz.

Regards!! THx
