  1. Similar to DualMonocles no spark no ideas problem, Im not getting any spark under cranking. I get spark on the test feature, but none under cranking. All of the accessories work and continue to work under cranking, as does injection, just spark falls off once the starter activates. The injectors and ignition coils are on the same circuit using the same power source, so this is pretty confusing to me. One thing worth mentioning is that I have not 100% verified that the injectors work under cranking, but I can smell fuel so unless I have an unidentified fuel leak I'd have to say the injectors are working. The Ignition coils are grounded, have signal, and are receiving a consistent 11.8-12 volts. The only thing I could think of is that I have the Ignition coils ground with 2 relays so maybe this is causing interference? Thanks, any help is appreciated.
  2. Ignition test does not fire coils. This test had been working on my Audi A4 with a 1.8T (Coil-on-plugs). I stopped getting spark around the same time a connector broke and shorted two of the wires, causing weak intermittent spark. I replaced the connector (correctly) and nothing. Also worthy of note, at the same time as replacing the connector I ran the fuel pump for around 15 minutes to drain the tank which I know can be connected to the same positive rail. To troubleshoot, I unwrapped the harness a decent amount to check for shorts and everything looked good. I unsoldered the new connector and capped the wires. I checked with a second set of ignition coils and spark plugs. I checked ground, and bridged it just in case. I'm still getting 12v delivered to the coil packs, and have double checked all the fuses. I haven't changed any ecu settings, and spark mode is set to falling edge (I tried rising edge just it case without success). I reinstalled the software, reset the ecu to factory setting, tried the Audi TT base map and anything I could think to do like restarting my computer. When the test is set to run, I do see battery voltage drop by around 0.5V. The only thing left I could thing of is that the transistor doing the switching inside the ECU is not functioning properly. I'd like to test with an oscilloscope, but it's currently packed up. Any ideas or advice?
  3. Hi team We have wired in the lem g3 with g4 software no worries. We have now come to the problem is that when cranking we only have spark to cylinders 1-3 witg 4 producing nothing under ignition start. When testing spark via ecu there is spark on that port so there is definitely no issues there. Was just wondering why nothing is happening when turning the key. Cheers
  4. Hi all Recently my cylinder 1 spark plug has been fouling badly and becoming carbonised I have done a compression test and compression is perfect and equal across all cylinders I took a driving log and was wondering if there was anything in the log that might indicated why it is fouling up, the log is pretty big so zipped it with 7zip Thanks in advance all Log 2018-10-18 7;41;11 pm.7z
  5. I'm in the process of converting the stock 4G63 wasted spark coils to direct spark COP setup and appear to have hit a speed bump. I've just gone into the manual and PCLink software and it appears that to run sequential ignition you need to align the output with the firing order (IGN OP 1 to Spark 1, 2 to 2, 3 to 3, 4 to 4, etc)? The issue I have is that ignition outputs 3, 4 and 5 on the EvoLink IX PNP are already used for other functions; fuel pump, A/C Fan, and NB heater respectively. Coincidentally, ignition outputs 6 and 7 are available (both physically unwired) therefore making them ideal to use for a mini loom to control sparks 3 and 4- but I don't believe I can program them for this??? Is this a software limitation (that could be changed in PCLink/ firmware), or is it a hardware limitation of the ECU? I am reluctant to start moving pins about within the stock ECU plugs, hence the query.
