Default Terminator X with T56? VSS? Reverse Lockout?

Doing some research on putting a Terminator X in my car. 1996 Z28 with a junkyard 5.3L and a T56. I would like to use the speed sensor in the transmission and also retain the reverse lockout just in case. I have contacted Holley about this and they have basically told me that I'm on my own. There is little info on how to wire this up online. I know you will have to use the I/O's to run it. Does anyone here have a setup like this and can point me in the right direction on how to achieve this? The goal is turbo in the future. Thanks for any help!!

Should be easy.

VSS is just a 2 wire VR signal, and the lockout solenoid just needs grounded when you wish to be able to engage reverse.

So find a spare input for a VR signal, and spare output and just do it.

Although odd for Holley to actually say that to you for what should be simple. Hardly great customer service ?

They told me that I would have to find the signal that needs to be sent. What I find hard to believe is they make all the steps nessacary to wire in a auto. But not a manual when its literally 2 sensors. I would think that a manual trans is a pretty common swap. Sounds to me like they got lazy and are leaving thier customers with a manual out to dry. Providing no solutions and saying "you'll have to figure it out".

I used the 7" screen with GPS for speed and put the reverse lockout on a toggle switch since I was out of I/O and since it wasnt a daily driver.

I went with MS3pro because of this. Front ABS and rear speed sensor were plug and play because it has VR conditioned inputs. Instant traction control.

You will need to find a way to convert the VR signal to square wave if you want to input it into the termi,X

Pretty much how I plan to do it.

Can the Holley not take a VR signal directly ? That's a bit ****. No big deal to convert to a digital signal anyway though

If the speed sensor is the same as the TR6060 it should be fairly easy but will use one input and one output, I'm running a Dominator not the Terminator X but it looks like it's configurable in the X software I have on my computer.

Good idea! (didn't want to quote the images)

Holley seems to have terrible tech support recently. I've heard the same from multiple people that were told the same thing when they called in asking simple questions... "read the manual" "figure it out" lol thanks!

That said when I Holley swapped a TR6060 I just left the reverse lockout unplugged and pushed against the spring when I needed to go into reverse, maybe not the best option but I hardly noticed after awhile.

Another simple way is to just hook it up to the brake pedal, You'll activate it every time you hit the brakes but it will keep you from using inputs and outputs.

bit pointless buying an ecu to not use them for functions you need though, and for basic essential information the ecu should have.

I am using ABS sensors for speed for traction control, use the GPS for mph on the dash but could have used mph from one of the ABS sensors.

With Holley its important who you buy it from, everyone tries to get the lowest price then complains when they cant get service. If you buy from a good dealer who uses holley and offers tech support then you will way less headaches.

Very true but if you're limited on inputs and outputs it's an option or you spend more money on a system that has all the inputs/outputs you need.

What is essential about the ECM knowing the reverse lockout is actuated?

Lets face it, its a $700 ECM not a Motec, Halltech, ProEFI, etc... that cost many times more.

Ya ABS sensors work for F/R speed comparison. Usually its the tuner that gets to sort out all the Holley problems, most aren't too bad but a couple were asked to send their units back in.

You really arent understanding what an ecu does.

At no point is there a sensor telling the ecu whether it is or not...because that is an OUTPUT function

Dont be so thick, never said it had a sensor. I said the ECM knew it was actuated which it would know if it was triggered by an output.

You said reverse lockout is an essential function which didnt make sense to me as its never been a requirement for Holley or any other ECM. Nice to have, but nowhere near essential.

And nowhere did I say reverse lockout was an essential function. A speed signal however is a very different matter for a variety of control features.

Speed signal is not essential. Wheel speed, driveshaft speed, etc are nice to have but not essential in any way.

Speed signal matters for idle control, boost control, for logging. So yes...it is essential unless you want a very basic shitty system.

It'd be like saying coolant temp, air temp, throttle position etc are not essential. An engine can easily be made to run without those....but it'd be ****.
