i find the hpt interface to be clunky and and annoying to navigate and use but the efilive package is extremely useful. its log viewer is light years beyond anything ive found elsewhere. But it seems like 99% of the gm tuning community uses hpt and i never really understood why.

 

Exactly. Logging in EFI is so much nicer, even just the GUI. I think the HPT logger looks cheesy and a PITA to setup or change. I also prefer the list format for the tuning when trying to find a table as opposed to having to hunt and peck for a specific tab to find a specific table. Their forum I've found more responsive as well when dealing with specific issues.

 

The DIY tuning winds appear to be shifting.....
HPT might have to do a little(??) attitude re-adjustment....

 

If im looking to make the transition to EFI live for the GM platform, should i be looking to buy the v3 Flashscan module?

 

I have had efi live since it came out and used it daily for 10+ years. Hpt scanner is better than efi and easier. Hpt also has a search where you just type the name in. You can make them both look almost the same. I switched to hpt purely from a business stand point. I used to do about 50/50 efi and hpt email tunes and sold alot of efi and hpt setups. Around 2013-2014 it start shifting to more and hpt and less efi. Now in 2021 its 99% hpt and maybe 1% efi. I like efi and they have been really good to me over the years but they pushed all the main gas tuners away when they switched there business model towards the diesel. With hpt being about to tune some many different vehicles, the lower cost and popularity of it, it makes efi a hard sell. I have got less than 5 calls for efi all year.

 

V3 is the current hardware for efi live.

 

and I almost forgot the BEST feature of Hp tuners?? If you are logging and you close your laptop screen, or the screen gets closed from vibration--you get the BLUE SCREEN OF DEATH and the laptop completely shuts OFF! Yay HPT is the BOMB!!!! NOT!!!!! HPT personnel state "we are not car tuners, we are programmers" and yet as programmers they can't prevent your laptop from crashing while using their program?? Very nice.. Or.. wait... not so nice..

 

I've used EFI since V1 and have used HPT for a long time as well. I don't like the HPT layout or logging GUI. To me HPT is Apple and EFI is Android and I prefer Android and EFI.

 

HPT has always treated me well. I’ve had no issues.
When I was tuning at a shop, I brought HPT on board for the Dodges. They were using CMR Diablosport. Within a few months they were converts.
We worked closely with HPT at that time finding tables that CMR had but HPT didn’t.

The Holley is great for engine swaps for sure. But you can’t toss that on the late model cars where the entire car system is tied to the ecu.

So I’m with minitrker on this one.

 

I wish I invested in EFI live instead of HPT years ago. But I am not a good tuner by any means. I get by making small changes and still learning. I'm more of a carb guy. But every year at LSFest, I ask them, "when are they coming out with a multiple OS for the duramaxes like EFILive. Its pisses them off..... LMAO.
Love my DSP5. Stock to stupid with a few clicks.

 

Like this




Its only for LP5 though. I still use efi live on diesels. Never even looked at diesel tune in hpt.

 

Bill at HP Tuners forum gave me some misinformation about changing the VIN and I lost two credits. He played it off with this stupid answer:

Pissed off I stopped the payment from my bank on the lost credits. HP Tuners didn't like that one bit and I received this e-mail:

They were threatening me about bricking my new never tuned with device that I was $600 invested in (with credits).

After a few e-mails back and forth explaining how Bill gave me bad info telling me it would indeed work then trying to weasel his way out of the situation I received this:

I swear it's probably easier fighting city hall or the federal gov. than fighting with HP Tuners

 

This may be the only instance in existence of HPT admitting they were wrong....so quoting for posterity

 

Print it and frame it! Then plaster it EVERYWHERE it can be seen.... lol

 

I've guess I've never really had a problem with HP Tuners and I have been permanent beta with them since 04. It probably helps that I had 3 fully filled up MPVI1 interfaces and was working on the 4th but either way they were always pretty responsive when I needed a table added, etc. I use it daily and can only think of a few issues over the years but otherwise I just don't have problems so not sure how others can have so many issues. EFILive used to be good back in the day but I sold the cable a few years back as they aren't even close to HPT on later model GM gas vehicles anymore.

 

Your post actually proves the point perfectly. Unless you're dealing with them regularly and dropping large amounts of money filling up MPV interfaces with credits, they couldn't care less about you.

 

That definately seems to be the theme here. Its all about the $$ that drives what type of service and treatment you receive.

 

While back there was a long thread about this, originally Trump started pulling funding and power out of the overly aggressive EPA (my opinion), then Dem power started putting that back.. but NOW there's a new development. States (and countries) are passing "right to repair" legislation and that topic is becoming a bigger policy issue than the minor pollution concern:

https://uspirg.org/blogs/blog/usp/ri...s-slowing-down

So, HPTuner's life as a company allowing self-repair may continue.

But as far as HPT goes, their reputation of bad support and bad customer service has been "just what they are", I knew about it before I bought mine and still bought it because I liked the solution best and trusted it most. That is, until my non-firmware-updated MPVI-1 Pro breaks and I send it in for repair and they refuse to return it because they are allegedly trying to rid the whole world of hardware that can work with the hacked versions of their software (google that, I'm not making that up, apparently any MPVI-1 they get with old firmware is blackholed according to other forums I read, but I personally can't back that up).

I don't condone piracy or theft, I use the product as designed. But at face value it appears that they allegedly intentionally tried break their hardware for everyone (with hidden firmware update) so it can't use ANY older software (which included the hacked version that was spreading around back then), effectively punishing everyone to "try" to prevent the few criminals out there from misusing the solution (all allegedly), that's where I draw the line if true. The next set of credits I need I'm going to test out the donation type software on my VCX Nano or MX Plus. It was bad enough that it drove a market for firmware DOWNGRADE services.

EDIT: here's a vid describing what they did with the firmware push, he also mentions the MPVI Black Hole rumor (I think starts at 42 or 43:00ish, he actually states they are keeping all MPVI1 units, not just old firmware ones): Here's the link to the other long thread when the word started getting out that they could be doing underhanded things: https://ls1tech.com/forums/pcm-diagn...-heads-up.html

 

The tuned/deleted diesel world is being rocked as we type. Of course it's happening when I decided to upgrade my turbo and some other goodies on the Duramax.

 

I am EXTREMELY curious to know if/when the EPA cracks down if it will render all MPV2s useless because you now have to be connected to the internet to confirm licensing in order to flash. If there is no license server to access, does everyone end up with a paperweight....
