EDIS Megasquirt idles but dies on throttle

Cor, not easy to type sat in a Fury

My car idles, but cuts out as soon as I move the throttle. It recovers when I lift off. I've attached my MSQ and two log files, the first it just idling, the second where I attempt to add some revs. Any pointers as to what is going on?

are you running a TPS?? This could be operating in reverse??

Calibrate your TPS. It currently goes down to -3. Multiply your entire table by 111%. Then add warm up enrichment of 111% at 60 deg C. That should bring the AFRs of 19 to a drivable range. Take a datalog driving around keeping revs down < 2000 and throttle < 25% for about 2 minutes. Use this data to automatically correct the table using VE Analyser in MegaLogViewer. The car should then be warm enough to be off warm up enrichment (> 80 deg C). You can then take a longer data sample (5 minutes) to make more corrections to the table. If the car is feeling good by this point, you can start to use more revs and more throttle, making corrections every 5 or 10 minutes.

Yet again, idiocy strikes. It would run better if my MS knew it actually had 4 injectors rather than the 8 I told it it had.

Time to play tomorrow.
