Good motorsports capable ECU is going to be $1500 min
solid state programmable PDM $800 min
data logger with GPS, accelerometer $400 min

That's an $1100 difference and three different software programs to wrestle with vs one. Then you have to get those three components talking to each other via CAN. Then you have separate patch harnesses to connect everything, possibly running dual sensors where CAN coms aren't possible.
Big picture, I think its ultimately a better value to go big now since we're doing the harness from scratch for the new engine anyway.

Add ~400 for an i/o expander box as well, (with plugs and wires and stuff) 800 for 2 for the extra i/o (and that still only gets you 6 AVI, plus 6 ea DPO and DPI) you get natively with the Nexus vs the Elite, and it is a wash. Plus the ability to use the CAN keyboard as well.

I ended up with the Cartek 16 channel unit. Simplifies the wiring by a LOT, and even I was able to figure it out. Not cheap but it's very nice for what it is.

I'm going to bump this thread as I am looking at an Amplink so I can get rid of the engine mounted fuse/relay box. Having problems with the main relay even after I pulled the fuel pump load off with a standalone relay. Sometimes I go to start the car and I can hear the relays clicking on and off.

My plan is:

Circuit 1 & 2 to handle the BTN fuse items (stop, hazards, and tail fuses)
Circuit 3 & 4 to handle the cooling fan
Circuit 5 to fuel pump
Circuit 6 to take place of main relay (injectors, IAC, VVT) and add room fuse (ECU power)

Anyone have anymore experience with these? I'm also thinking of mounting this in the engine bay where the old fusebox was so I won't have to extend wires.
