Peace

Thank you Adam for explanation. Mainly i wanted to know is this a big issue or i can just tune around it. So if thats what is comon i just setup everything to ignore TPS delta up to 8-10%. I will also try to take a look on the sensor as you said.

Hello I'm struggling to fight TPS delta. On a full throttle run TPS delta shows oscilation in +/-10% which causes CLL to be locked, and Transient ignition trims to be present. Yeah i know i can setup CLL and Trims to not act in such precentage TPS delta but i want to try and find the reason why this happen. Any idea? My build for information is RB30(26head) with EFR9274, 280(10) cams, with stock RB26 ITB Attaching my log file. If needed can put a tune also TPS DELTA why.llgx

Try borrowing another timing light. I got fancy US-made timing light which cannot detect spark on cranking due to low starter RPM (i have an RB engine), but when the engine is running it detects it right away. So i have to use cheap chinese timing light to calibrate my triggers on starter

Try to put charger on your battery and charge battery during update process, this helped me.

Adam Can you advice controller which can do this job? There were AEMone, but i believe it is discontinued now.

Why dont you want to post here for everyone?

Tank you very much for this explanation.

Luckely i have ID1000 which are illustrtaed in link help file as example. Can you advice on how to read ID data correct. For 1300x there are alot of negative short pulsewidth adder, how can that be?

Thank you. I will do another test. I Thought i should see knock level and decided that i got some trouble with connection of sensors. Update - I did the test as long as the knock system operating i get knock level readings, thank you, that was not obvious to me

Yeah i understand that the knock system was not working. So knock level will read ZERO and it is ok? I thought that even on idle i should see that my knock sensors are reading something.

I did not saved a log where i revved up my engine, so only have log on idle knkPC Datalog - 2022-08-9 12;25;35 am.llgx knock.pclx

Hello Yesterday i finished wiring in Bosch Wideband sensors to my g4x ecu, and then i started the car to check, but my knock levels were 0 all cylinders. I tried with normalized mode and put some throttle to see if there will be change but no change in knock levels were. Then i tried just Ign retard mode and put 200 as a gain, and anyway my knock level on all cylinder stayed zero. Yesterday i quit troubleshooting as it was late already. Today i start some google and see that it is common to see ZERO knock level when idling, is there a way i can check that my knock sensor correctly connected inside link software or i need to drive with some load to check if there will be knock level rising?

Thanks for replying i also thought it is because of very small plenum on a GTR What can you suggest to diagnose comms? I was not looked into details because it was a log of a 50km run without throttling hard or anything was just driving along the highway. And i was not worried about weirdness of log.

Hello I have a strange behaviour of MAP delta it is jumping and is very hight even at idle with 0% tps. And most of the time it is oscilating. My car is ITB RB30 so maybe it is normal for ITB setups with very tiny manifold to act like this but i wanted to check with you guys. Here is a screenshot of my log. Can post a log file but its quite large from a big portion of driving, and i dont know the way to split in into some files. Screen shot 1 Screenshot 2 Wanted to give CLL a try but found i need to set up realy high map delta threshould so CLL begin to function, if i put reasonable values like 10 or 20 KPA/100msec CLL stays always in LOckou:Map Delta Anyone have expirience with such behavior should i just bump up Map Delta lockup or i need to search for trouble in my wiring, sensor? But map reading themself is pretty stable not oscilating

This was during engine run but RPM not very stable but picture is pretty stable these part always lower than the end. My question is this decrease in voltage cause an issue in ecu or as long as lowest reading is far more than arming threshold this will not cause and issues. Do i need to address this? or since ecu dont care actual peak voltages? because since the complexity of my setup this centering problem of 0.1mm maybe very difficult to find and correct.

Thank you for clarification I will be trying more But somehow if i set sync tooth less than 30, there is backfire in exhaust, thought if i disable injection and do a trigger calibration with sync tooth = 1 it still fine and show on crnak exact what i ask in the trigger calibration pop-up. Than what make me think it is trigger related? Maybe you can take a look at trigger scope logs and give me advice is it ok or no? I think i need to adjust arming threshold And one more thing confuses me, after the first trigger 1 teeth, peal voltage of the wave of teeth falling a little up to 17 teeth from 10 to 7.5 volts and after that increasing and this picture is clear for all my scope - looks like my wheel is a little inperfect. Is this an issue or as long as it is within aring threshold it is fine?

Hello Can someone take a look and say is it normal or not I have an RB30, with custom 36-1 wheel on crank and 1 on cam, both are reluctor wired on stock engine harness Link g4 never had trigger scope and trigger setup had less options so i set it up on g4 6-8 years ago pretty easy. Now with a fresh build and aiming for a better power i upgraded to g4x and here i faced troubles That sync tooth thing i cant understand. With practice i found that my trigger is happy with sync tooth from 30 and up to 35, less than 30 and it start to sync a little slower, less than 27 it started to backfire in exhaust But what i can see at trigger scope is that trig 2 happening at 26-27 teeth so as i understood description of sync tooth it should be tooth before cam even occur - but it does not work for me here is how my trigger scope looks like at around 1000 RPM - this is about 0.5-0.55mm gap on both sensors some days before - i had gap closer about 0.3mm and i had issues with positioning i think. When i was trying to calibrate trigger it was giving me spark, next 2 -3 times i try to crank there is very poor spark on plug and it is not enough for strobe light to catch it so i decided to increase gap - and thats help, now i always have spark. I have picture of trigger scope if needed but dint think its relevant. And finally - when that trigger gap were tight if i manage to start engine it was working fine, but now it starting every time but can only hold 500-600 RPM for short period of time and than stops. If i add Throttle it can get to 1500 or 2000 but car feels much worse than before with tight gap. Yeah this is not yet completed - not connected exhaust and Wideband yet - so maybe it is a tune issue, but quick changes in cranking enrich, warmup enrich and fuel table 1 not help me, and with tighter gap it was working good, only thing i was worrying is that at 1000 RPM with 0.3 gap i was seeing 16v at trigger 1 and if i remember correct 6v at trigger 2. Never have expirience and looking at typical arming trheshold table that was working fine for me on g4 i thiught thats too high. Also my concern is that although i dont have trigger error counter increase while engine running I get trigger 1 states like counting timeout I tried increasing arming threshold as i see pretty high voltages but that didn't helped and i returned them back. Thats why i want to verify i'm good with trigger before continue to fine tune startup
