  1. Had an hour or so this afternoon. That lambda irregularity was 100% lack of fuel... I enabled CLL at 0deg,to allow for Lambda Target Overlay Added Lambda Target Overlay from -0.100 cold) to 0 (80c) Added 1 Lambda gain across table Added update rate at 1 across the table Added more air at idle, where required Added more warmup enrich. The above has made a massive improvement. My lambda is flat right from startup. I did initially add too much warmup enrichment but CCL trim log is giving me a good idea where to tweak that now. Much happier with the cold to warm idle now. Dashpot works better too but still lumpy(because of 15c ignition angle and lumpy cams),I guess I can reduce hold and decay times to activate idle Ignition Control quicker.
  2. Regarding the lambda, are you sure? I would expect so, if it was a 4Cyl but its a v6 with 2 banks. I would expect to see both banks to be rich/lean. If I'm not understanding because I'm a noob, then why would the enrichment cause an inconsistency between banks? I've noticed since my previous post, I've plumbed in the Link boost solenoid wrong, potential for an air leak. I hope that's it.. SO much conflicting info out there for those solenoids... It was getting lean at 70c so added in warm up enrichment. Would it be better to turn up the CLL activation to 80c and leave the enrichment at 70c? Thank you both for your support BTW @Adamw@essb00
  3. Had a go with the dashpot settings, also carried out the open loop idle procedure again...added a bit more %. It just doesn't seem to like anything regarding the dashpot. Coming down the revs it does some weird dip to hunting before it settles to idle. I did have a loop with MAP lockout and dashpot but raised the MAP lockout slightly. I'm also having a Lambda inconsistency which seems to be worse from cold and gradually gets better (but not still not balanced). Playing with Cylinder Fuel Trims (+4% down Bank 2) seems to help, and then moreso when Lambda CCL kicks in.

  4. Thanks for having a look. I did follow the ISC procedure initially, but changed the idle base a bit since..maybe I'll redo it. I never considered the dashpot. I didn't know what it was! I'll set it up tonight. Would you recommend add 10% offset and add a second to hold and decay? I'll also add in 10deg to min clamp. Many thanks
  5. I've currently got the Idle Ignition Control defaulted to 300zx map. I have played around with target, min and max clamp but didn't make any noticeable difference to how jumpy the control was. Proportional and Derivative gain, I don't completely understand yet. 15jan2022.pclx
  6. I'm probably just after confirmation, unless I do have an issue with my map.. I have installed, a set of JWT cams - notoriously lumpy idle (272/.385" [email protected]) in my Nissan 300zx '90. I can't get the car to run at all without idle speed control. With ISC on, it's close to stock idle (RPM target 750, warm). Idle Ignition Angle is erratic. My theory is ISC is battling Ignition Angle because of the lumpy cams, is this correct? And is this acceptable? Thanks PC Datalog - 2022-01-9 2;21;01 pm.llgx
  7. -40 and it's fired (need clean underwear - high rpm!) I wouldn't say it was bob on, but it's as close as I've gotten...
  8. Just tried this and it barely cranks. Presumably all fuel, no spark. Also thought I'd blast through some offsets for clues; -180 - fast crank, no firing -200 - fast crank, no firing -300 - best bangs -310 - pops -280- pops and occasional bangs -290 - pops -320 - regular pops -330 - less regular pops 60 - turns slowly no combustion 80 - turns slowly no combustion I'm going to keep going, but concerned about endless cranking with no oil pressure.
  9. Hi. I have a Nissan 300zx and wonder if someone could scan through my trig and map log please. Self confessed ECU noob here, but learning! At best I've managed to get a little combustion out of her, but not started. The timing on the ECU I locked to 15deg with an offset of -345. This brought the crank pulley timing to 15degrees. I think I just can't seem to get the timing right. Ive tested all spark and fuel individually. Injectors are 1000cc so set fuel master to 6ms. If I add fuel via master trim (10%), I could barely crank it. I appreciate any support that could be provided. Thanks! PC Datalog - 2021-09-7 2_10_44 pm.llgx TriggerScopeLog2.llgx
