M800 shift function vs GCU for paddle shift

[XSESIV]

Has anyone had any experience with controlling a sequential gearbox via paddle shift using the M800 shift function as apposed to using a dedicated GCU like Geartronics? What are the pros and cons of either option?

Got a Holinger sequential in an Evo 9 time attack car with some paddles and DBW. I prefer not to have a dedicated GCU for complexity and an extra device to worry about but does a GCU give any performance or mechanical sympathy benefit over using the M800 shift function?

Been trying to compare both options, the only things I think the M800 can't do is engage reverse only when speed is zero, use a neutral lockout via button, deal with any dog-to-dog situations, start a throttle blip before down shift and maybe auto down shifts. Has anyone found ways to do these in the M800?

I've got some experience with controlling sequentials and paddles using Motec ECUs. Drop me your email and we can share experiences.
