I, by far, do not know the particulars on this. Thank you for clarifying!

Did Holley ever release the specification for their CAN bus protocol for this unit? I would like to add support for it for the stuff I work on, but I can not find it anywhere.

The closest I have found is from 2015 for NHRA specifications which appears to be Holley's modification of the Racepak CAN protocol.

According to people inside of Holley they do not plan on releasing it to the public.

I can see where something like that would be VERY proprietary.

Azxiana

I will have to pick up an unit and reverse engineer it then.

Haltech(By email contact) and AEM(Right on the web site) both provide their specifications for free. It would not be difficult for Holley to do so either, but some companies are secretive about things that do not need to be secret.

I searched through this thread and also Googled but didn't find an answer:

Does the Terminator X setup actually monitor and show oil pressure via the OEM GM gen III sensor? Other swaps I've done don't use this sensor to start and run the engine for early gen III. I was looking to eliminate the OEM sensor and run an aftermarket gauge and sensor in the rear port of my LS1 and tee off to my Porsche sensor for my swap so the gauge will read actual oil pressure. I'd rather not have 3 oil pressure sensors but wasn't sure how the Terminator X computer would react to missing the OEM oil pressure sensor. Thanks for any help!

I believe in video 2 of the TerminatorX overview video on my YouTube channel, I talk about and give the part number of GM sensor that plugs right into the harness. The oil pressure plug is part of the main harness. You also use any other 0-5v sensor that you want and do a custom calibration in the Sensor ICF, provided you know the sensor output values. The oil pressure plug the is standard 3 cavity Metripack 150 connector that is commonly used for pressure sensors.

Apologize if this has been covered.

But would this be street legal? Could you pass ODB-II emission test with this ECU?

It will not pass, It's a stand alone system so you remove the stock computer so the port no longer functions.

The Holley system does not need the oil pressure sensor to run but it would be a good idea to use it just for the safeties that Holley is capable of. Basically you can program it so if the oil pressure drops below your preset threshold you can command it to shut off the engine or other strategies that might save your engine.

Knock sensor options for non LSX engines?

Thank you both! I appreciate the inputs.

Not a requirement to remove stock ecm, you can keep stock ecm and obd2 port and set all readiness codes to pass even if you removed all the sensors.

Good idea! What the ECM doesn't know wont hurt us....

Any sponsors out there having a black Fri deal for the Terminator X kits?

LLLosingit

You'll probably have to call them, They aren't allowed to advertise a lower price. They advertise at the price Holley tells them to. The Holley Days sale going on now lasts until the end of the year and then the price usually goes up higher than it was before the sale.

The terminator x are excluded from the holley days sales going on through Dec 31. We can help out a little (PM or email for prices) but there is no smoking deals on them after shipping and processing fee's there is very little margin left on them.

I ended up contacting MCB and they gave me a great deal on the Terminator X kits for my LS1. Now my question is I plan to add a turbo and with only 4 I/O does anyone have any recommendations on what they should be used for?

Depends on who you plan on controlling boost and what else your going to use for inputs. 4 go quick.
