TMS374 ECU programmer TMS374 MCU ECU decoderTMS374 ECU decoder is a Auto ECU programmer, it is frequency sweeper with 5V square wave output. TMS374 ECU decoder can be also considered as a MCU version of the software TMS 374 Decoder ECU. (Duty cycle 50%, effective frequency range from over 10kHz (max 50kHz) to 50Hz). A small tiny2313 MCU is used to generate the pulses instead of the PC RS232 Tx line. The TMS 374 software is in fact a simple frequency sweeper with an effective range from about

A small tiny2313 MCU is used to generate the pulses instead of the PC RS232 Tx line. The TMS-374 software is in fact a simple frequency sweeper with an effective range from about 2000Hz to about 100Hz. The Tiny sweeper does exactly the same but much more better (bigger range).

The TMS 374 software is in fact a simple frequency sweeper with an effective range from about 2000Hz to about 100Hz. The Tiny sweeper does exactly the same but much more better (bigger range). After powering the device on - the LED should blink twice. Pressing the button will start the sweep procedure. LED ON - means there are pulses on the output. After reaching the lowest frequency the LED goes off and the mcu stops the generation.

Manual:
After powering the device on - the LED should blink twice. The sweeping process starts as power is supplied to the device. LED ON - means there are pulses on the output. After reaching the lowest frequency the LED goes off and the mcu stops the generation.

* Connect the GND line to any suitable GND on the ECU via the small grabber.
* Connect the Data line to the Reset pin on the EPROM via the small grabber.
* Power the ECU and then the sweeper, the sweeper will flash twice on power up.
* Press the button and the device will start sweeping, once the LED turns off your done.
* Cut the immo data line on the ECU before re-fitting back to car.

NOTE: If reset pin is connected to ground then it must be lifted or the track cut before decoding. This can be re-attached after decoding the ecu. As a rule of thumb keep the power connected to the ECU for a futher five minutes after the decoder has completed the decoding process.

Procedure:
Simply power the ECU and device using a suitable 12V power supply. Connect the GND cable to a good ground source on the ECU and then the data line to the Reset Pin on the flash27c512 or28F512 as shown in the diagram.
Start the device and wait for it to finish its cycle (the led will turn off). At this point the ECU has been decoded and put into a new state. The Immo line will need to be disconnected before the ECU is re-fitted back to the car.

Vale is an 8 month pregnant omega working as a waitress at a strip club and a cam girl. She starts to get very creepy vibes from a regular at the club, and her baby daddy ghosted her. She has had an online relationship with a man named Bishop through her cam girl status. One night, bishop was paying to watch her sleep and ansthe creepy regular Andrew break in and watch her sleep he tells vale to come to him at his business now. She flees and finds herself at a large security company with some.hot of alphas who are there to help her. This imegaverse is a little different than I have read, but I am thoroughly enjoying it. Vale is not a traditional omega she was raised by a single beta mom, and the alphas are not normal alphas they have never really loved pack life. But they are ruthless mercenaries. They need her, and she needs them. I love the aspect of the stalker and now the plot twists at the end, so so good. Sometimes, it seemed a little slow and stale mated, but since this a duet, I think It was just her starting to have Vale get to know her alpha suitors. Cliffhanger for sure with this one.

That ending 😫
Format: Kindle
I fell into a false sense of security and really thought this was gearing towards a happy ending. Then I realized there’s no work they don’t punish Andrew. I really liked Vale’s character. I don’t normally read books with pregnancy but going into this knowing she was pregnant made it more enjoyable for me. I loved Bishops devotion to her and her happiness. I also loved that Holt and Mercy couldn’t fight their attraction to her. I love scent matches so very much. I’m so curious to see how this duet will end up. And I need to pay more attention and notice that a book I’m starting is a duet to begin with lol

I just knew there was something about Cooper! I’m wondering if he’s about to be included but damn I’m glad he’s at least not a rapist and creepy guy, he just got called on assignment and had to go! This should be interesting! She’s gonna run and then what’s his face is gonna grab her. I’m worried! Wow that was a great book and cliffhanger! Loving this!

Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.
