    Duramax swapped Trailblazer SS...you might say why?...I say why not.

    Guess he must have found someone closer on the FB. Sent from my SM-S901U using Tapatalk

    T87 Swaps

    Also received the T14 adapter prototype yesterday. Not bad for the first attempt. Terminals fit and release correctly. Robin the seal and wire guide dimensions from the OEM connector also works great. That orange is actually a printed silicone seal. However he made one mistake on the outside...

    Received the two new switching options today from the Chinese rain forest. Along with a package of micr-clips and some Long needed jumper wires. Now we can crack open the TCM again and get technical on its GPIO functions. It might not be pretty, but I'll bet I can get it all wired up to...

    I gave FB a 5yr lifespan back when it made MySpace obsolete. Internet sites always seem to run in lifespans, or attentionspans, I should say. FB just figured out how to keep your attention viewing click bait, and charge advertisers for it. As where much older forums like Redit, are just now...

    Duramax swapped Trailblazer SS...you might say why?...I say why not.

    Someone Rang? I actually just saw your post over on FB. And just so happen to have a pretty complete stand alone LB7 harness all wired up on my desk, that's being used for bench testing some FICM stuff. Dayton is a couple hours from me, but I could probably swing by in next couple weeks. How...

    I bet he really enjoyed that heated seat.. :D Ferrets are a cool pet if ya can house train em. Had one as a kid, lived outside, and it loved to hunt. We would turn it loose around the hay barns, then stand outside the biggest rat hole with golf clubs.. She was a rat cleaning machine.. Have also...

    Here is the final of T14 connector prototype. Should have one Monday to verify the fit.. What ya think?? Sent from my SM-S901U using Tapatalk

    I didn't have time to check the amperage on these new sensors yet, but I noted the resistance across pins. So think if we just loop the Vin to Vout through a relay, it should be well within specs. I smoked the amp fuse in my volt meter a while back. Will try to get something setup to measure...

    Yeah the one that doesn't go down to zero is the first 2 pics, the 2016 factory sensor the T87 calls for.. What we also noted is the TCM seems to look for a specific resistance value on the 9vRef line. Won't clear the circuitry related codes when I spoof it with the arduino.. So bet we put...

    @2004LB7 I had to read your reply a couple times to catch the drift.. I've been playing with a stack of diodes and resistors in combinations. My first thought was lower the output voltage on the VR converter from 5 to 3.3v with resistors. However that's when I noticed the converter board only...

    That is the OEM speed sensor reading 1-3v normal. Where our Arduino and VR converter sends 0-5V outputs. But the TCM will read both the Arduino and the factory sensor fine. It doesn't accept the 250mv pulse from the VR converter when connected. That is the one getting knocked down from 5v to...

    Here is our new 2016 output shaft sensor live, connected, and reporting good on the TCM. You can see the min / max voltage values. It shed 5 volts from it's disconnected state. Also note it actually never drops to 0v. Next up is our Arduino Emulator running a 40 tooth pulse pattern. It...

    Broke out some lumber and zip ties, solved the new style VSS mounting issues. :D Ran some tests last nigh with a SnapOn scope to look at how these new sensors and the Arduino works with the T87, but our nifty little VR converter doesn't. Looks like it comes down to output amperage limitation of...

    One piece print looks like it will work. Now just add the seal area, clean up the edges, and call this a good prototype we can start with. Stay Tuned.. Up next, got some data off all our sensor options... Sent from my SM-S901U using Tapatalk

    T14 Connector Revision # 5 Seal on wire terminals won't fit the 3.5mm pitch without overlaping the insulation crimps. Maybe if injecton molding in mass it would gain the 0.3mm that we came up shy.. So, it's back to the OEM matching MX150 style. Now to print the whole deal in 1 piece.. Maybe...

    I've been going in the other direction, making newer trucks go back to Pre E-log standards.. But I would like one of those blind spot detectors to add to my wife's Ford Edge. Ya can lose a big rig in that cars blind spot..

    Yeah that looks interesting.. Specs says output is +-20ma. And that seems to be the problem. While the Arduino outputs same 5v range, it must push more current that the TCM will accept. When you hook up the Max chip to the signal line, it reads zero volts. As where the OEM 2016 sensor reads...
