    Two questions

    Because your regulator is rising rate the math channel on the Differential fuel pressure will add negative manifold pressures (actual rail pressure 310 as the regulator is reducing the fuel pressure 1:1 to the vacuum.) It will also take away positive pressure, this way the DFP remains a straight line in the ideal world enabling you to spot issues easily, just like Richard did on your log. I can't see the timeframe on that picture and I cant open the log from my phone he size of your feed line may be too large, when the regulator tries to raise the line pressure the volume of fuel the pump needs to change is too much for it to keep up.
  2. The confusion comes from changing a base map to Link CAN Lambda as the ID overhangs from the base setting, would make sense to get PCLink to inherit the correct ID when the settings are changed. The default ID is 950.
  3. The Idle Control Lockout is an adder to the base idle target which now means when warm your car will be e strategy at over 2700rpm, you should set this back and look at why the idle is not coming down, maybe ignition is hanging. Set an Aux out to come on when RPM is over 600 for 30 seconds and use this to trigger the wideband relay.
  4. The CAN Lambda has a default ID of 950, PCLink defaults to setting it up on 1000, but you can change that and it wont take effect until the next reboot of the Lambda, just dont use 1000 or 958.

    Map switching

    You could simply use a flex fuel sensor which will sense how much methanol is in the fuel and then adjust for you.

    Map switching

    What are you trying to achieve ?
  7. Your firing order table is set wrong.

    Knock block

    I have one available www.shopbhp.com
  9. Have you gone trough the crank trigger calibration where you mark TDC and lock the timing to 0 degrees and adjust the offset? Once this is done you can move on but do not alter this figure again. You can turn vvt off for low engine load tests and illuminate a VvT issue. if all is well carry on and set the VvT up.

    Drop the gain down, adjust the knock target so it’s just above the noise.
  11. I would find some intelligent coils that do not need an ignition amplifier (Less to go wrong and much tidier wiring) make a new subloom for coils using +12 from a nice new relay with a 15A fused feed from the battery and the coil of the relay ignition switched. Ground all the coils locally at the engine and run 6 new trigger wires from the ECU. You will switch the ignition mode to direct spark (as long as you have enough triggering - crank and cam sensor) and set the correct spark edge and dwell settings.

    Are you 360 degrees out ?
  13. Change that to : Driven wheel speed source is set to: OFF Non driven wheel speed source is set to: LF Wheel Speed
  14. You will need to wire and assign a Digital Input and assign this as ALS, once you have done this you can trigger the Antilag with this switch and configure the settings.
  15. Under Chassis and Body what is your Speed Source set to ? If looking here does not solve your issue please upload map and log file.
  16. No worries buddy; it's easier to work when both axis are the same so either work in absolute or gauge pressure and not both, so choose one and it will be easier to tune for the brain. You engine will not want 14.7 AFR from -100 to -40 kpa MGP at all revs, your also using super unleaded which is 14.5 stoic anyway, and you will want to be somewhere on the rich side of this while your engine ROC is positive but you have no control over that with your current AFR target table as its not fine enough at the bottom. Your overrun fuel cutoff being on is stopping you from mapping the low end of the table because it is sending the Oxygen sensor into a massive lean condition, so turn this off while you are tuning. Also your Closed loop lambda is making the mixture map almost impossible, just look at the 2750 spike and all the corrections going on.
  17. More getting the axis correct in revs and pressure, weather you use MAP or MGP or PSI makes no difference as both are only a math calculation of the raw ADC.
  18. The problem you have is that the mixture map is using the AFR Lambda target table to work out what fuel ratio is required and where you are getting the spikes you have no direct relational axis so it has to guess, once you have a base tune use the mixture map and get the axis of the AFR table in sync where you need to tune it better and don't correct the sites you have already done. Also turn off Lambda correction and overrun fuel cut while tuning or you will get no-where.
  19. Yes, its there for that exact reason it will also mean that Lambda 1 is Stoic.
  20. As a note UK pump super unleaded fuel is 14.4 Stoic as is most fuel worldwide where Toluene is used as the octane booster.
  21. Boost Targets are Absolute, because of this I find it easier to do all the boost control settings in MAP.
  22. You have a target of 150 and are making target pressure, do you mean to set your target to 250 (1.5 bar of boost) ?
  23. Check the trigger with the built in trigger scope (ECU Controls - Trigger Scope), save a log and report back here.

    Spark plugs

    Difficult to see the plug looks old but there is a lot going on, the plug is to cold, the timing looks too advanced and the fueling looks ok, you say 11.3:1 but you haven't said what fuel you are using.
