Blackbear tune to disable security, rear O2s...anything else???

[Dariusz Salomon]

On my 1998 Suburban, after disabling VATS using Jet's DST I have no "odd" lights. All is good.

I've run Jet's DST on WinXP and Win7, haven't tried it on Win10.

Most of my "tuning" stuff I run on WinXP (TunerCat, Moates, Jet, others), except for DIACOM which I run on Win95.

Thanks-I see pricewise jets and hp tune are comparable(to some extent)- is HP as capable as jets-number of options you can modify-or you need"Pro"to match?

I can't say... and unfortunately my "Jet" laptop isn't close by (90mi away) so I can't post any screengrabs of Jet's DST for comparison. If you're willing to wait, I can do so later in the week (if someone sends me a reminder anyway).

Sure-not a pressing subject but it sounds like an interesting idea-plus since I'm not in the US possibly only option to get things done with my baby. Maybe pinger and I can join forces in buying it together if he's interested?

Also on Jet's-I found it on amazon and some of the reviews say it's gotta a job to work on windows newer than 7-what system have you got it installed on?

FWIU the newest version of JET DST comes with a USB interface box/cable instead of the serial cable they originally came with, which should take some of the difficulty out of getting it to run on a newer system. I have no experience with JET DST personally, but I would imagine that you could run it in Windows XP "compatibility mode" in Windows 10 or 11 without problems.

If you do purchase it I would contact the seller first and make sure they're shipping the new version with the USB interface, as seen in the pictures here on JET's site.

Keep in mind that HPTuners will only communicate with '98+ PCMs in these trucks. If you have a '96-'97, JET DST/TunerCAT is pretty much the only option I'm aware of.

Mine is 99 so no issue there-but thx for heads up. And I just found the pdf on how to install it for windows 10 so looks like it would work.

I changed the fuel gauge update rate by doubling it (I think OEM rate is 60Hz, but whatever) to take the "shake" out of the fuel gauge... a common occurrence on that era truck.

This actually worked?

Works perfectly.

Change this parameter from 59.5 to 119 to double the frequency of the PWM signal which drives the fuel gauge (image from JET's Dynamic Spectrum Tuner is shown).

I'm from Canada so there is no such things as emission testing, etc. My local exhaust shop was going to tune the rear O2 sensors out when they did the exhaust but I decided to do it myself.

when Canada is more MERICA than AMERICA lol

I have JET's DST running on my XP laptop.

I haven't used it in a while and had forgotten how many different configuration screens are available.

Take a look at the menus across the top (see image), i.e., Switches, Constants, Tables, ... Each of those has a set of submenus to screens that allow configuration of this or that. It would take me a while to capture each and every one of the configuration screens, since there are many.

The image also shows the Constants : System Parameters configuration screen, and of course the entire screen isn't visible without scrolling; notice the slidebar on the right-hand side of the configuration screen.

If there's something you're looking for specifically, I would be happy to capture the relevant screen and post an image here.

Nothing specific for now-thank you. Looks tasty enough.
