I don't know if this will help you ghwallice. I bought one of Cliff Jefferies ECU's about 15 or so years ago and installed it on a Guzzi I owned at the time. His ECU is basically your old unit gutted and installed with his. It plugged into the Guz electrical system and you then uploaded the map and off you went. The attraction was that you could hook up a data cable from your PC or laptop and plug it into the ecu, extract the map, have a fiddle and then drop it back in. I got my map off a bloke in Tassie, Phil Arnold. I hated the vibration on my V11 and Phil helped me change a number of parts of map to richen up the fuel ratio. The bike still vibrated so I sold it and bought a Laverda but found it had the same problem. He certainly would be able to help you because he's into any engine and love Dry Lakes racing so I'm sure he's easy to find.
To use a MYECU I'm guessing that you need to dovetail the wiring system of this ecu to the Lav electrical system/TPS/sensors etc. I'm sure Cliff J would have a bit of an idea of the wiring requirements because that's what he's into. I recall he didn't have much of an idea when it came to the mapping though that may have changed by now.
From memory map writers use Microsoft NOTEPAD and I think still have it I think if you want a copy. Below is what one of the maps I was given looks like.
# TDC is the pulse count for TDC power stroke of cylinder 1 ( i.e. When the spark fires
# CylOffs is the number of degrees between success cylinders ( 0-720)
# PulsesPer is the number of pulses for the 720 degree 4 stroke cycle
MyECU Cfg TDC=0x1600, CylOffs=270, PulsesPer=48, MissingPulses=3
# CoilCharge is the period in us for charging the coils. 0 for cranking, 1 for running
# Warning, Setting coil charge too high can cook the output transistors and coils
MyECU Cfg CoilCharge0=6000,CoilCharge1=2500
# Pressure - mV and mB values defines a line representing the air pressure conversion
MyECU Cfg Pressure=249mV,121mB,4199mV,1060mB

# There are 8 possible voltage targets available 0-7
# The first number for 0 should be 0.0 and means open loop
# For simple sensors where richer is more voltage, all numbers should be positive
# For later sensors where leaner is more voltage, all numbers should be negative
MyECU Cfg O2=0.00V,-2.25V,-2.75V,-2.50V,-2.25V,-2.00V,-1.75V,-1.50V,
MyECU Cfg 2ndO2Sensor=yes
# RPM specifies the maximum RPM.
# TPS specifies the throttle value at idle (no fast idle).
MyECU Cfg RPM=8620, TPS=56
# TDCWhileCranking=1 will fire the spark at TDC
# TDCWhileCranking=0 will fire with advance from the map
MyECU Cfg TDCWhileCranking=1
