Summary of Changes for the v2:

• Lambda Display Option
• Extreme Range option for FI methanol & laboratory applications
• 0.411-1.373 Lambda
• 6-20 Gas AFR
• 2.66-8.88 Methanol AFR
• Increased display speed
• Bosch LSU 4.9 Option (Not recommended for methanol)
• Methanol Display Option
• Faster analog output
• All harnesses, control units, accessories, etc (except the LSU 4.9) are backwards and forwards compatible
