Hi, Attached is a more complete log. Cheers PC Datalog - 2023-05-21 10;43;39 am.zip

No problem, attached is the new log. My laptop did seem to have a connection issue midway through where some data for ect between 30-60 degrees was lost. I will take another log when the engine cools down. Thank you.

Hi Adam, I am very glad you mentioned the acceleration enrichment issue. This is something that I have been playing around with, yet to yield a good result though. The values for that log file are just the standard sr20 settings that I was testing. The previous settings I had attempted to tune are located in the tune file attached and yielded the same problems described. Also thank you, the an error high value for anvolt 4 was set at 1.75V! Thank you very much 13toedit.pclx

Hi all, Have an sr20det with a linkG4x. Currently running into a driveability issue when the engine is cold. Upon any throttle input when cold, the engine hesitates massively for a second or two and then appears to be fine, even at that same throttle posistion. This does not happen as the engine warms up to operating temperature. Upon taking a log, it appears the fuel pressure drops to 0 as this is happening, then returns to normal. Again only when cold. RPM and MAP cut limits arent met when this is happening either. Could there be some other reason for the fuel pressure loss? Thanks in advance if you can offer any advice. Attached is a log file of a relatively long drive, showing the issue when cold and absence of the issue when warm. Thanks, Jack PC Datalog - 2023-05-17 5;12;04 pm.llgx

No worries, thanks for your advice, i'll give that a go.

Hi, I've recently installed a G4X Fury ecu into an s13 silvia with sr20de (distributor igniton). Started tuning the car and all was well until the rpm signal was lost around 6000. Ive checked and don't believe there are any limits active. When a run was logged, a trigger 1 error occured at the time when the rpm signal was lost. I'm wondering if the ecu is not seeing the correct amount of teeth at this rpm because of the high tooth count of the Nissan sensor combined with its age, or potentially another problem. The sensor is wired as shown in the help file, to sensor ground. I did read another post where someone suggested changing this to engine block ground as is apprarently factory. I have attatched the log file with the rpm signal lost and trigger 1 error, and two trigger scopes, one at idle and one at 5000 rpm. If anyone could provide any feedback, that would be much appreciated. Kind regards, Jack PC Datalog - 2022-06-22 7;59;17 pm.llgx trigger scope 5k.llgx trigger scope idle.llgx

Just ran a new power supply for the distributor/cas, managed to set the base timing and get it started. Thanks again for you assistance.

Hi Adam, Thanks for your reply. I've repinned the triggers accordingly. You were correct in thinking that either the pin 5 or 6, power or ground were missing. I've attached the new trigger scope log, which looks much more promising. I will try to time it now tomorrow. Thanks again for your assistance.repinned.llgx

Hi, I'm currently in the process of installing a G4x fury into an s13 silvia with an sr20 engine (s13 de with distributor ignition). The issue im facing is that when trying to set the base timing of the engine, my timing light does not flash at all. To ensure it is not a faulty timing light it has been tested on another engine. On wiring connector A, Trig 1 has been connected to 'Pin 3' of the distributor (360x as referenced in the Haltech Image), Trig 2 has been connected to 'Pin 4' of the distributor (4x as referenced in the Haltech Image). When continuity tested, from the distributor plug to ecu plug, this matches. The triggers have been configured as layed out in the help file. The ECU is powered, unlocked and able to be connected to. When cranking the engine with the F12 'runtime value' interface open there is no engine speed, trigger 1 or 2 signal, trigger 1 error, fuel or ignition cut or engine kill change at all. When the ignition driver 1 is set to test mode, with each lead connected to a spark plug externally and earthed to the engine, a physical spark is made and the timing light is functional. The car has a new battery, as well as a jump pack connected while cranking. I have conducted a trigger scope test, which appears to have some data, although I am unable to interpet its validity, and have attached this test and the ecu file to this post. Any assistance in troubleshooting this issue would be appreciated. Kind regards, Jack last test.llgx s13.pclx
