For support engineers I suggest e.g. 10-25% damage resistance as long as they repair anything manually. Also as an extra, repairing a generator or terminal could provide speed bonus (20% for 10 seconds?) (let's say only completion) and maybe even some xp/cert/ISO bonus. If wanna help repairing vehicles, there could be also (another implant) increasing max repair nade held which may do or not stack with Bandolier. Idk if e.g. reducing rep nade nanite cost by 25 is an option. Or maybe there is one extra nade every time only, but is resupplied for free?
I really like the extra rep nade idea. There is precedence for that sort of mechanic in the Experimental Stims implant, so I would think it could be done.
I like the equip speed as it also helps with c4/Archer/Carbine/repair switches which may be helpful in various situations. As engi is at disadvantage when leaving a vehicle. Idk if it can be even at 70%, probably not. This needs to be combined with some other benefit. Other ideas buff repair like the original so I don't think those can pass.
