Charlie The 3rd generation appears to have a sender life estimate based on response time. Might be worth the extra $20. Bobby Hughes In OH for the next few months with no airplane. But I purchased a renesis FWF yesterday for an RV8. Spare parts to build a turbo setup for the 10. Anyone need a Sam James rotary cowl or tech welding heat exchangers?

The PLX site lists 'gen 3' at $219 w/'discounted shipping. I can order through Amazon Prime for $199 w/free shipping, but it's listed as 'gen 2'.
