Getting a SecureChannelFailure both when trying to resync device, as well as just open "about" to check for updates.
Suspect Mono issue?
Win 7 pro.

Anyone else seen this recently?

Yea. Well anyhow, uninstalled 4.x stable again, but this time installed 4.x beta, and it seems to be working now. Havne't had a chance to test long term, but isn't freezing near instantly anymore.

Seems like quite a few people experiencing this. It's been driving me mental, as I JUST finished a new build and absolutely require some logging to figure out a few things, but no scanning :(.
I...

Bin repo is down. Got a customer that's about to burn down my shop because I can't finish his truck till the segment swap is complete.
Anyone happen to have an 07ish 4l80e bin with OS 12597120?

I used to prefer HPT, but I'm now investigating other options.

Something to keep in mind is the current situation with HPT. IE: Once again, customers website accounts have been lost, and the bin...

It was a few weeks for sure. Essentially, I'd talked to them pre-sales and was told my OS had 4L tables supported. Bought the tuner, no tables. Emailed them about it and they said they could do it,...

What vehicle? As I said, you can just wire an intermittent switch directly to the ECM, bypassing the BCM entirely. The truck I've got this working in, is ... half a 4runner with some land cruiser...

Wait, you HAVE 4L shift tables? If so, it's not using that table, most likely, because your low range signal isn't making it to the ECM. I'd start there if you already have the low range tables....

HPtuners did eventually add the low range tables to my OS (different from yours), but I found the performance tables to be far more robust, as their low range tables just give you a single shift...

I need to hear from a few guys who've got 2000 Silverado 5.3L/4l60e 4x4s.
What speed does your low range 1-2, 2-3, and 3-4 occur at, and do you get TCC lockup in low range?

Since reading my stock...

Don't get me wrong. I'm brand new to HPtuners, but the math required to work out the VSS PPM is very simple, and every OS I've ever seen, with any tuner, including HPtuners, has the correct values....

Yes, I absolutely can just use another ECU. But the problem isn't the ECU itself. Oh shit, I forgot to update this thread with all the new info.

Okay, so I was originally blaming DiabloSport for...

Well turns out I have yet another problem I have to solve before I can take this back to the trans builder.

I feel like a noob, but I didn't notice this when I first used HPtuners on this truck....

Currently running P01 with OS 12205612 in my 2000 5.3L/4l60e. Donor was a Silverado 1500.
Long short, I don't have, and do need 4L range shift tables. I'm told by HPtuners support that they cannot...

I would've built it myself, but I was super pressed for time. Trans conked out right before a trip I'd had planned with my daughter. Needed something quick, and sourcing the parts in Canada would've...

Was running what I was told was a stock tune, but found out that wasn't correct either. I always have my ECU's flashed to remove VATS and a few emissions by LT1swap.com, but now that I've got...

Paid a trans builder to build me a 4065e with TG HD2, Sonnax Smartshell, Vette servo, etc. I'd normally have never considered paying someone else to do something for me, but I couldn't find a donor...

Well I've got a guy who miraculous saw my FB post about this and is bringing me several ECU's. Is there any benefit to going to a late model ECU? Is that even possible? Or is the 00 going to be the...

WTF. I didn't see anything about 12 credits per model or 30 credits for all LS1 based.
Just trying to figure out what i need to tune unlimited gen3 vortec 99-07. I thought this page suggested it'd...

1. I figure buying enough credits for unlimited model/year (for Gen3 99-07 Vortec motors) makes sense. THat's VCM suite with it's built in 8 credits, plus an additional 12 credits, for a total of 20...
