    ECU Unlock fails

    Someone has done a typo by the looks, The last two characters should be b7, not 67.

    Yes, error values are adjustable. 68F is 20 Degrees Celsius so its possible that's the error value. The event log will tell you if you have any errors logged.

    Your fuel pump set up and the fuel pressure increase solenoid on ign 8 all looks to be ok to me. Have you actually tried adjusting the fuel? You say "stock engine" but the master fuel is set to 8ms. 8ms would be typical for injectors around 1000cc. If you have the stock 440 or 550cc injectors then the master will likely need to be more like 13-20ms. That doesnt sound like anything to worry about to me. If you want to do a more scientific test, pull both sensors out and hang them in a cup of ice water.

    lambda going lean would line up with fuel delivery problems. Because you have it working with a factory ECU we can likely rule out mechanical issues - blocked air or fuel filter, faulty fuel pump, bad regulator, etc. Based on this, this only this I can see in the config that would impact fuel pressure is if the fuel pump isnt being controlled properly by the link ECU. I'm assuming all the pinouts etc are correct, which just leaves the fuel pump control being wrong - maybe its not sending the right signal to run the pump at full power, maybe the PWM signal needs to go to 12v instead of ground or vice versa. Looking at the wiring diagram, these dont run a simple on/off relay, but a separate fuel pump controller, and there is a pin that is PWM'd to tell the fuel pump controller how hard to drive the pump. My money is on the config for this pwm signal being wrong (or maybe on the wrong pin, so it stays on low power at all times) - hence my suggestion that if you dont see any improvement from ecu config changes, put ground or 12v straight to the controller so it runs full power, then you know what the voltage needs to be and can work backwards from there to make it happen.

    I think its something to do with your fuel pump control causing the pump to shut off or go into low output mode. The bit where your foot is flat, but your RPM is dropping is the key point for me. Can you get your wideband running so we can see if its going rich/lean while the revs drop at full throttle? Alternately, get a fuel pressure gauge/sensor installed? Maybe try setting the fuel control cutover to something like 4k & 50% DC as a test, and if that makes no difference, try disconnecting pin aux2 from the ECU and applying straight 12v to it (which should force the pump to high throughput mode)

    There is no cuts or limiting out of the ECU so can rule out any limits. As CJ pointed out that ignition timing is odd and should be corrected. Fuel flow has been checked? Pump is running?

    You will need a non driven speed assigned but this can be the same input as the driven.

    Fuel Pump Control ECU

    Just wire the relay(s) low side to an Aux out as a "fuel pump" and it will automatically turn off the relay if engine RPM is 0.

    Cam Position Parameter Lag

    It doesnt do this. If you have configured spark as "direct", its always direct.

    Low voltage at ECU

    If you are measuring that voltage drop across the relay and using the same ground for each measurement then it is not ECU related. There is something up in that relay area.

    I assume it's still on stock dizzy? If so put ref timing to 16 degrees, try 119 in trigger offset and see if it'll start. When changing you need to make sure you press enter when doing changes otherwise it wont change. You'll also need a timing light to get the trigger offset perfect but it will start if you keep changing the numbers and its close. Keep trying and go up in 20s until its close then lower numbers each way. That's how I done it and then used timing light to get it perfect after it was close.

    Cam Position Parameter Lag

    I think the problem probably is you due to not using a compatible trigger & VVT mode. Your Inlet LH error counter is continuously counting up and the Inlet LH signal is reporting extra pulses. Try setting trigger mode to M52 VVT and VVT mode to M52, this should work with the single tooth cam and 60-2 crank. Trigger offset and VVT offset may need to be set again with this change. If that doesnt help please post another log and the tune file. I suspect something is also mechanically wrong if this is the case, in my experience the 2 state vanos is usually near instant switching (less than 50ms at a guess), you dont normally need to consider cam position at all, usually just switch VE tables at the same time the vanos is activated.

    Low voltage at ECU

    What is AN Volt 4 function set to? I think from memory it is the narrowband oxy sensor so you will need to change the fault settings to low = 0.0V and high = 5.0V. Your resistance to ground doesnt sound right - how are you measuring this - between which pins/points?

    Re: BASE MAPS

    The plugin base map packaged with the PC link download would be a perfect starting point for that.
