Thanks Adam seems that’s the only combination that doesn’t work. If you know you know…

Looking at the trigger scope (set up to rising) the two long 'pulse' sync points are too close meaning any slight variation is going to throw up a error... ? this is correct right ? if that is the case how on earth do i solve that issue ? its only the two long sets that seem to line up causing the issue the other 2 smaller are fairly close to 50% or good enough. I cant win with either falling or rising as on that one cam 'tooth' it traces both almost perfectly.

Tried again today and car now runs with no random rpm jumps although still has some crank trigger errors. as it ran i took a trigger log. I didn't change a thing just a different day. so ? Thanks Trigger Scope Log running 2023-05-16 5;18;54 pm.llg

Hi there We have had an ls1 running for 2 seasons no issues. well apart fro a bent rod end of last season.. that aside we have swapped out to stroker ls2. Crank came with a 24x wheel engine loom has stayed the same. so 12v feed to both crank and cam. Crank is 24x the dual style wheel.. sensor is the ls1 sensor 12v feed. Cam is a 4x with a ls2 sensor (requires 5v) but is working on 12v (i am going to put this to a 5 volt feed but it seems to work fine) I've done the wire swap to the sensor as the power is switched between ls1 and ls2 sensors. (loom extended) the engine ran great for 60 seconds with a few trigger errors. Tried again today to check on the trigger errors and now it runs but for a very short period with some rpm spikes to 20000rpm ign cut takes over and shuts engine down. a fair few trigger errors I have checked the trigger scope and the crank and cam are falling and rising at almost exactly the same time. could the voltage reduction help? i don't really want to cut into the loom unless i have to, the wires currently wont stretch for a re-pin. I don't really see how it would but worth an ask... apart from potential sensor failure. trigger mode ls1 5-10 rpm filtering 1 trig 1 hall filtering 2 pullup on edge rising trig 2 as above scope attached Thanks for looking Trigger Scope Log 2023-05-15 4;22;18 pm.llg

Thanks for taking a look. 100% i will be increasing the logging speed. wouldn't have picked it up to those speeds but will definitely will try. thanks Fully understand and can now see the timing going back in each time i get back to the same site. its not knocking, this is just setup so ill change the settings to help me there. Thank you. so the screen shot below this is due to the TPS delta lockout.. ill again log it with the additions you mention.

Hi guys Working on a 350z with a plug and play ecu G4X running a Link wideband knock sensor. While trying to setup the knock thresh-holds I've got the ecu pulling timing with the knock levels way under the threshold (can be seen in the attached log) the ecu is also loosing knock signal, as in all levels go to zero, sometimes the threshold goes to zero. doesn't seem to be related to anything i can see. The lock out targets are all reached. I've looked multiple times and cant see anything in the logs so its probably obvious, fingers crossed The only thing i can see is the TPS main isn't tracking TPS target 100% (this is the stock Link e-throttle map). When looking at the logs it does seem to have a tracking target issue inline with some of the knock dropouts. I'm logging at 50hz Any help would be greatly appreciated.
