hey, Adam i was finally able to get my hands on a scan tool with a scope functionsnap_on_scope.zip

Perfect I will reset me trigger one to the above and see if I can find a stand alone oscilloscops !

Would the next logical step be to send the ecu into link ?

hey, so the crank sensor has a fixed location with no wiggle room to allow me to move it closer or further away from the tone ring, the tone ring appear to be in perfect condition. I did remove the timing belt to reseal my water pump I didn't have to remove the crank gear/ tone ring or oil pump all went untouched, i also checked for "crank walk" and I didn't get the crank to move forward or backward with a prybar. from blue wire to valve cover with ecu unplugged the multi meter doesn't change from the default screen with ecu plugged in I get between .5 - 1.1 ohms Black/white to valve cover unplugged no change from default screen on the multi meter, pugged in I got a reading of 53.5 k Ohms (i can only assume this is from running though the ecu?) I agree it seems very odd to have such a big drop in voltage, i must be missing something I've done ? Unless it’s an ecu issue? Which I could see being an issue the wiring check out the sensors on sit in one location and the stock ecu can still read the sensors with no issues. scope 3500ish.llg scope 5000ish.llg scope 5000ish #2.llg

ok I have updated my trig 1 as above. things seem to be a lot more stable. I've also swapped cam and crank sensors before updating trig 1 and it made no change in how the car "ran" I checked for resistance on the crank sensor plug, if go from the black white wire to pin B-16 I get .5 - 1.00 ohms with the ecu unplugging. and then for the blue wire in the connector I went from the harness connector to the valve cover I get 0-.5 ohms when the ecu is plugged in and no response when the ecu is unplugged (Pin out used is the one I sent previously.) trig 1 update scope 1.llg trig 1 update scope 2.llg trig 1 update scope 3.llg trig 1 update scope 4.llg trig 1 update scope 5.llg trig 1 update log 1.llg

ok so tonight I ended up changing out my cam position sensor for one of my spares also changed the trigger setting to an LS (saved that as well) before reloading my tune I'm for sure still having an issue with the car drooping out of sync with the cam position sensor ever few revelations... new cps data log.llg new cps scope 1.llg new cps scope 2.llg new cps scope 3.llg new cps scope 4.llg

Cam position sensor ground to valve cover reads .5 ohms

Unplugged

Ok pin 17 bounces around 5M ohms to 2.75 M ohms pin 24 is 0 to .5 ohms I originally had the wrong pin 17 i did also add a new engine to chassis ground after testing the wrong pin 17 a few hours ago I found one pin put but it says pin 16 is the cam position sensor and that just gave me 1.477 K ohms

hey, i added a new engine ground and took some new scopes, I also to a data log as it randomly started hunting for idle and stalled new ground scope 1.llg new ground scope 2.llg new ground scope 3.llg new ground scope 4.llg new ground scope 5.llg new ground scope huntimng.llg new ground scope hunting 2.llg stall log.llg

if i am correct in locating B17 then my resistance is 1.232 ish K ohms

ok I updated triggers 1 and 2 to the values above and i took 6 scoops and one datalog I hope this is adequate, thanks again for all of your help so far! trigger 1-2 updated tune.pclr 1 of 5.llg 2 of 5.llg 3 of 5.llg 4 of 5.llg 5 of 5.llg 6 of 5.llg running datalog with both triggers updated.llg

trigger update.pclr it should have been this one, if this doesn't help I can redo both the scoop and dat log tomorrow after work.

I posted my original tune from before I had the issue, I miss understood what tune you where asking for on Facebook. The one that made the car run is that same tune but updated trigger 1 values

hey guys I'm a little stumped, for some unknown reason my injectors and coils stopped firing ( some down time for maintaining the car, I know I put the car back together as it was before, I get injector signal and spark when using the stock ECU so I know its not a forgotten clip/ anything from maintaining the car.) my cam position sensor and crank position sensor are being read by my Link so no issues there as far as I can tell, I re-uploaded my tune and tried the link supplied Altezza base map still no luck getting injector pulse/spark . After posting on the Facebook Link support page I took the advice of some guys and lowered my first Three Trigger 1 aiming threshold values 0 RPM= 0.2v 1000RPM=0.3v 2000RPM=2.0v After doing so I did get my injector pulse and ignition, the car starts and will idle for a few minuets. I'm still looking for the root cause of my issues as I shouldn't have to change a known working tune. Any advice would be greatly appreciated unkown 02.llg Trigger Scope Log 2020-08-15 5;18;36 pm.llg OG tune.pclr
