Holley Terminator and Sniper
We have another one coming in tomorrow for a car here.
I dont think it would that big of seller. It would also coast a good amount in material and time so dont see alot of profit in it. The biggest issue I would worry about is connecting a new holley system to a 20yr car harness that probably has issues, cant even think about all the tech support phone calls that would involve.
I tell you - if a company were to make a hybrid harness that allowed you to run the stock ECU (crank, cam, VSS, etc) in parallel with the custom ECU so the stock computer can run the factory dash vs splicing wires the old fashioned way, there is money to be made. I bet there are people out there who would pay an extra few hundred for it.

there might be something there if you could make it cover more than just the p01/p59 vehicles. most of the NNBS trucks are e38/t42&43 ecm/tcm or e67/t42&43 combos...and don't forget the weird e40 here and there
and then the sprinkle of tac modules and pedals and different OS's for them all
yeah that might be pretty hard actually

Indeed there is, hell I'd pay much more! Corvette guys going to ProEFI and Dominator would pay an easy $1000+ for that feature to keep OEM dash working.
Meanwhile C6 guys are spending $7k+ to incorporate Holley into the vehicle and keeping the stock ECM so the dash works for just what Darth said above. Having fully rewired my last car I'm sure I can do it, just haven't sat down and looked into the wiring diagrams to see what a C6 dash needs to work. But if guys can make a Porsche dash work with an LS swap I'm sure we can get a GM dash working with Holley.

That would involve having several different harness for auto, manual, Z06, C6 there is no easy one plug n play harness. There are a couple C6's, camaros and a G8 out there with dominators and working clusters its just a lot of time which equals a lot of money. We can take the stock cluster out and put in touch screen a lot faster vs making stock cluster work.
for those getting their gen 3 (single wire knock sensors) engines set up, some data for you
AC Delco PN 213-3521, GM PN 12589867 – Commonly used on 1998-2006 GM LSx engines. Baseline Frequency – 11.1 kHz

Anything can be done with enough time and money. We have made all kinds of oem dashes work with LS swaps but it involved a 3rd party company making a box to handle just the gauges.
That would involve having several different harness for auto, manual, Z06, C6 there is no easy one plug n play harness. There are a couple C6's, camaros and a G8 out there with dominators and working clusters its just a lot of time which equals a lot of money.

Should be just a "simple" can translator and 2 wire hook up to the stock harness.. Put the info needed by the gauges on the GM network.
Does holley publish their can data?

What exactly are they doing? Are they just keeping the dash working or are they also keeping the ABS, Traction Control, Airbags etc all working as well? What are they doing with the accelerator pedal, spitting the signal?? There is a HUGE difference between just making a dash work and fooling the vehicle into thinking the stock ECU is in control.
What about states that have smog or at least have inspections? You'll never be able to legally piggyback a stock ECU off an aftermarket, sure some people might be able to get away with it but when you do get cough its not going to end well for someone.....and it's not the person using it thats going to be in serious trouble, its the person/company that made it possible.
And a lot of the foreign car dash boards are easier to make work then most domestic stuff.

Does the TCU on the Terminator X Max accommodate paddle shifting. With my current setup, I have a 4L80 with a US Shift controller connected to a 2 button TCI Outlaw shifter. When I press one of the buttons, the manual (paddle) shifting is engaged. When I press both buttons at the same time, manual shifting is disengaged. Hoping that the Terminator X Max TCU will allow this feature. Anyone know?
Not trying to hi-jack the thread but this post cough my attention.

Inspections are literally the easiest thing to get around, same with emissions. Really you aren't supposed to speed either, but we all do. I'm not sure why you would want stock traction control as it sucks. But yes depending what car and how much you want to spend you can make everything work, even with my basic Holley swap everything inside the car still worked off the BCM. You can certainly feed the ECM whatever you need to keep aux systems working. ProEFI and Motec seem to have plug and play options available, the Holley while much cheaper takes some configuring but entirely possible.

Not if you leave the OBD2 port functional which really doesn't take much and neither does setting the readiness codes.
