Holley Terminator Options
use a thermistor for your fans and that'll get you one output back. if you can live without logging your oil pressure you can log trans line pressure through there, but it's got a hard limit at 250psi.
i have just the bare bones set up for staging a turbo car and i'm already eyeing the dominator

also IME you can run the brake directly. it'll be triggered by the same wire that signals the holley to engage the 2 step.
I havent used the holley bump timer as the DIY ebay timer box works so well.

Fan really shouldn't trigger to come on above 35 or so, the natural air flow should be cooling the car correctly.
I want the fan to come on if the engine hits 195.. but that's me.. if it s a drag race setup use a switch. /??
I've found in general that a thermostat controlled fan lets the engine temps oscillate less.. And a stable temp = more reliability..

I'm running
Inputs:
2-step
e85
Dome pressure
Front wheel speed (still need to get this working right)
Outputs:
Boost solenoid
Fan
Water pump
2nd/3rd fuel pump
I have oil temp, coolant pressure, on board air pressure, and 2-step signal going into my 7" dash.

I didnt say those 4 would max it out...I said you will be maxed out.....every turbo car we have seen with terminator was maxed out and had to either have stuff hooked to the dash or put things on switches. 4 I/O dont go very far on most turbo cars.
i'm interested in that wheel speed thing. are you making a table of front vs rear wheels speed (i assume ABS from the front and VSS from the rear) as a way to have traction control?
i also have this idea, but i'm stuck thinking i'll need two tables....one as a by gear multiplier for the first table. so one 1d table for that and then one 2d table for front vs rear vs either boost pressure or timing...not sure which

Haven’t done it yet but my plan is 3D table, front speed as one axis and rear speed as other. Now your line going 45° up where both values are equal are where it ‘should’ be, above and below that line is when the speeds are different and how far off they are. Your data in the table can be timing or boost or whatever.
i'm not picturing how to do it with the holley advanced tables. if you make some headway on it, make a video or something?
found a thread on the holley forums where they discuss it a bit

Front wheel speed vs rear wheel speed....pull timing when rear exceeds front by whatever mph or percentage you want. Single advanced table.

you could probably use an abs tone wheel in the rear, I have used all sorts of different abs sensors to get a speedo reading.
but therein lies the problem with the terminator....you start running outta I/O's pretty quick. I'm already eyeballing the dominator

Dominator is definitely looking better and better.
