Thank you - i was able to do the v2 build 70 over usb cable without the SD madness and silly steps. But today had to do this for v3. It worked fine. Thanks for sharing

[TheCrouchMan]

Thank for making this video made the process easier for me. Just updated my handheld to v2.0.5 and ecu to v2.0.8

[BoWhiteRacing]

I’m waiting on my terminator x to show up I’m swapping from Stock computer to holly. Thanks for everything you do for us.

[boossersgarage]

thanks, a complete video, all the steps. not half like the Holley video. saved me from sending the unit out or having someone come over to rescue the ecu. Awesome....

[norego]

thanks matt you make it look like even an old boilermaker can do it

[rafaelmaldonado]

How did you build your bench harness can you make a video on how to build it

[MonkeyFabGarage]

Thanks Matt. Been semi stressed about this.

This makes Holleys video on downloading look bad… Thank you for making it easy!

[seanjhonson]

Thank you for this awesome info and simplifying this process!

[WTC]

The new version has a feature that lets you do barrel rolls like Michael Hastings

Can you show how to safely update Holley 7” dash and Terminator x with just a laptop. WITHOUT the LCD screen and SD CARD.

[laiky]

Great video! Holley doesn't tell you how to get to 2.7. they tell you its the latest software on the site, then you download it and get the mismatch error.

[BigRichEHhthang]

Can you teach us how to make the bench harness please

[b.c]

Never delete the content. If update fails and you need to return to last known good configuration you're screwed. Save the card content until update is complete dude.

[victorsalomon]

Great video man!! I do have a huge favor to ask, my saved GCF goes to open with media player, I try open as and I don't get a way to suitch it to .terx I deleted everything from terminator x and loaded again and nothing makes it work, tnks before hand!!

[Markstarscoobs]

i wonder if you can update this on any andriod or phone with an SD card slot. i guess one of us will have to try it.

[hiteracing]

So for the first time firing the car can you set all your I/o with the hand held or do you recommend using laptop

[GateOpenersDirect]

I just did all this exactly and followed your video twice to make sure I did not make a mistake but when I download those files there is no “tslcd” file loading from Holley to update the handheld…WTF HOLLEY? Can I get somebody to send me this file and just download it onto my SD card in the proper place? My ECU updated but my handheld did not so I can’t get any of the wizards to work and I’m dead in the water

[garybaumann]

Updated the firmware. Engine just pops and sputters. I have Snakeeater truck injectors. What setting do I use in the wizard for those?

[fastrucken]

@sloppy, can you ask holley if they would enable input B21 for the gm transmissions, Looks like on the 4r70 its an input that can measure line pressure. So we could monitor line pressure without using one of the 4 main inputs..
