Why not just use a holley terminator x system for the powertrain?

Terminator X and X Max GEN III HEMI Kits

Terminator X powertrain management systems from Holley that offer plug and play control for most Gen III HEMI engines. Why settle for a junkyard ECU with a cumbersome aftermarket tuning interface when you can take complete control of your engine with easy to use self-learning fueling strategies...

I know with HP tuners you can prevent the SES light from turning on but the codes will still remain. You can try disabling some of the configurations in the BCM but a lot of the settings/modules are interdependent. For example, ABS gives the IC/TCM/PCM wheel speed information. If you don't have speed, the PCM won't operate properly as some tables rely on speed.

Although I wonder what roadkill garage did to get the general mayhem to work with the SRT HC powertrain. I do remember them struggling with it on one episode as it kept shutting down.

@Mopar Frank didn't you mention someone being able to get the holley system to spoof the OEM modules?

Most people use the Holley Terminator X...........

 

Maybe you didnt undrstand....I am using the entire wiring and control system from the 2015. From the battery thru to the two fuse blocks and everything . The entire DASH and all controls. So I dont need a stand alone control for a modern hemi transplant. I am using the entire body harness and allot of the control modules from the 2015 SRT...so I need to modify what I have

 

Again all you need is the Holley System !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! read what it does.....................

How will the terminator X connect and work with the U connect and other dash / console controls?

 

Fuel Tech DOES NOT have products to access these items...per Fuel Tech

 

BTW I heard on one of the hot rod garage episodes (they were installing an SRT powertrain in the Savoy) that the holley terminator x does not support VVT?

 

Yes it does the newer one supports it....

 

lock the cam

ethanol carb

msd for the spark

its a wrap


not a holley fan these days. anyone watch the video? when he switched from 6.4 map to custom map so he could tune the cam did you see the numbers????? 17 20 wtf???? obviously not ECL - but what are they?????

 

So......back to my original question.


Discussion starter · #1 · Oct 24, 2023


I am looking to modify my 2015 BCM to remove numerous body modules for systems I will not be using in my 70 RR / 2015 Challenger project I am building. Im using the entire drive train, dash , interior and wiring form a 2015 SRT into a 70 Road Runner. SOME of the systems I need to DISABLE would be:

AIR BAGS
Anti-Lock brakes
Power WIndows
Power Locks
Rain/Light Sensor
Active Suspension
and Im sure there's more.

Some of the above mentioned might reside in the PCM.

AND NO..The Holley Terminator only does POWERTRAIN...NOT the Creature comforts that are IN THE CABIN of the car

 

Without ABS how do you plan to get vehicle speed? You can try disabling things in the BCM but you are in going to have to do some trial and error.

 

Haven't looked at a BCM for a while so take this as just something to look into. One of the ways to fool it is to set things to an impossible to attain value. That will effectively set it to off if it doesn't have an off setting. Some sensors can be fooled using resistors with a value that makes the PCM feel like they're working even though they are not.

 

Not using anything that needs wheel speed (hopefully) .Don't want to use abs, stability control, air bags - etc.

I haven't even tried to play with programming...was hoping to find a professional that has already done this before instead of "Paving the way" myself....

Yes but ABS is used to determine vehicle speed which is used by the engine and trans modules.

 

Im not sure the 6 speed has a trans module...?? does it? And why does the PCM need to know vehicle speed?

 

Manual don't have a TCM and tuning is greatly simplified but speed is still used. Do you have HP tuners? If so look up speed in a manual tune and you will see idle tables, rad fan, DFCO, power request (NV ratio which is RPM/vehicle speed) use vehicle speed (or VSS). If you go to HP tuners you can download a stock manual tune and check for yourself.

That said, there are several switches in the PCM tune you might be able to turn off VSS over can bus communication but that is out of my wheel house and I have not seen anyone mess with them.

If you plan to use the cluster you will also need vehicle speed which again comes from ABS.

 

If I was not using the stock EVIC there is no reason to run a Dodge PCM

Costs too much to tune and it was built for a smog mobile

 

Good information ! Thanks . Question....My build is using the rear suspension form a 2015 Challenger...but not the front suspension.. I do have rear wheel speed sensors which I can connect. If I don't delete the ABS programming and electrically connect the abs unit..but not physically connect it. Will that solve some issues?

Im using the entire 2015 Challenger interior.. Stock dash and EVIC

 

Honestly, you might want to think about posting your questions over at the dodge section in HP tuners as you will most likely get the answers you need from knowledgeable tuners. Most folks on CT forum mess with BCM configuration (and modifications to PCM/TCM parameters) but not to the extend of modification that will be required for your build. There was a member that joined who figured out how to mess with the cluster via arduino but have not heard from him in a while. Below is the thread he started which I tried to help him collect can bus data as he did not have a challenger...just the cluster which was going into a 70s vehicle (forgot the make/model).

I played hell getting mine to act right with 80” of rollout up front and 91” in the back

Can not imagine it not missing those 2 inputs

 

Did you get the BCM to with your setup. I’m doing the same thing but using a 8hp70. I’m about to go crazy. I have everything working (rear view camera, lights, radio, dash, elec windows). I also using the trans controller from Russel Drake. I think I need to get the ABS shut of some how. Did you get yours to work without wheel sensors? If so could you send me in the right direction.
