Consider a V8 with direct spark and sequential ignition (There goes 16 outputs!)
Add to that: FAN, Fuel Pump, Fuel Pump PWM, ECU Hold Pwr, 4 * ISC, CEL, and a Shift Light. (Which is a fairly 'reasonable' list IMNSHO).
If I've read the G4-Xtreme brochure 'correctly', it only has 8 Aux Outputs. (Apparently the 'older' Silver Box had 10, but the 'Red box' only has 8?).
Looks like I am going to have to swap my GM stepper ISC for a 3-wire (and still tie up every available Output pin!)
It WILL work, but I would have expected additional 'spare' outputs on the 'top end' Link ECU. (If I ever need an additional output I'll be forced to regress to a wasted spark with 2 coils on each ignition output).
(It's not going to stop me purchasing a Link. Just making a suggestion for the 'Link-Ultra')
