You've got similar issues with @Sushpants He's got it solved. Check out his thread (watch the video link he posted).

...to stop the intake backfiring on ignition on.

Hi... Since "Stop Switch" is 100% fuel & ignition cut, would something like this work? ...or maybe the "Anti Theft"?

If you connected the G1 instead of G2 for Trig 2, you'd need to have 360° Trigger Offset (+/- to what the timing light says for your set base timing calibration).

Which one did you connect to Trig 2? G1 or G2? I connected Trig 2 to G2 (G1 not connected). Have you got it firing up, or even just cough? Here's my starting trigger scope. https://drive.google.com/file/d/1TmxXrCms2e-0sOknldCZyNJXi45b-X0S/view?usp=sharing

@koracingGreat idea. Thanks. I've just made one.

@koracing I've just bumped the Trig 2 arming to 0.4v as I saw quite a lot of noise from trigger scope during starting. The cranking ignition angle as I understood should have been pulled from the ignition table, so I am unsure why it seem to get the ignition idle target 23° instead. Warm idle is already tuned (quick tune, with some point adjustments I manually made), maybe my previous log was just not long enough and it has not stabilized yet. It starts quite easily without a miss after being left sitting for a while (I really couldn't say cold when it is sitting 30°C ) @Adamw I'v

Quite strange that I can't replicate the hard starting now while logging. It has been happening the past days. I'll get back to this once I got something logged. Edit: Got one logged. Trigger errors appear whenever I release the start button. I'll also try to capture trigger scope whenever I catch it happening again. https://drive.google.com/file/d/1GsUwhFhxYjk_g7hKasJRN4OGG2lPYqJg/view?usp=sharing

Good day, Cold start fires up easily (though lowest we get is +20°C ambient). Starting warm (ECT above 60°C) however, the engine is hard starting/flooding. I tried reducing the First Crank Prime down to 50% but still flooding. Engine by the way is 4A-GE 16V small port. https://drive.google.com/file/d/1oA9wwDWNHeQtW8GrBXH81ak-qqBaUEui/view?usp=sharing

Hi @Adamw Just to let you know, since I updated to the latest firmware 6.19.37, the hiccups has not recurred yet. I have not changed anything other than update PCLink software and update ECU firmware. ...so it seemed that the hiccups I was having were caused by some sort of bug in the last firmware. https://drive.google.com/file/d/17xGlqKqUqD7hvB8ZJjuTrurAxadN_L_R/view?usp=sharing https://drive.google.com/file/d/1S-yKHXDysRuVF6izpmLn-6kmsAxg4J-h/view?usp=sharing

When turning the ECU power off, getting the following error in PCLink 6.19.65. Connection error: 1019 LINK_NOT_RESPONDING_CORRECTLY Not really affecting any functions, but quite annoying that I have to clear it every time I turn the engine on.

The status of the 'unknown USB device' does not change whenever I plug in/out the USB from the ECU... I've also have tried the procedure on the article you have provided on the link, and it didn't help either.

I guess it is not just about the 'Ports (COM & LPT)' not showing in Device Manager... I also don't get any device plug-in notification sound whenever I connect the USB cable from the ECU. So having to manually add the COM port does not help either. The option to enable/disable 'Ports' is no longer available in UEFI only BIOS. *Hidden devices shown on screenshot.

Turn on the DI 1 Pull-up resistor

I seem to be having the same problem with my new laptop... My old laptop and my wife's laptop both work fine. *Screenshot is from my new laptop's device manager. 'Ports (COM & LPT)' does not show (ECU is connected to USB).
