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 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.

Very nice if you aren't too pick on actual color.
Size: Single Pelt/2 ft x 3 ft, Color: Blue
Colors may vary. I really liked this, it was the perfect size and that perfect combination of soft and fluffy, but not being "too fluffy" and looking like a shaggy dog that needed a haircut. My only complaint was the color. Supposed to be blue, and I know monitors and lighting distort stuff but this was an obvious turquoise/teal. Much much greener than I was looking for. I could have made any variant of an actual blue work from powder baby to practically navy, but not this. I had to return, but other than the color, this seemed to be a very nice rug. Sad the color was so off.

I was concerned about ordering sheepskin online. So many scams & faux fur. And Wow! Holy Moly - I’m so impressed. I’m from Hudson Valley NY - lots of sheep farmers - I know fur! These are fabulous! Bigger than the others online Thick and full piles and beyond soft These are beautiful - I’ve now ordered 3 If you’re a renter and furniture came with the rental - these can transform your space! The colors are beautiful and appear very natural PS: Do not expect bleached white color And you really wouldn’t want it I have allergies and chemical reactions These are beautiful, supple and natural They come with a linen bag, cleaning brush and care instructions I’m so pleasantly surprised and maybe a bit obsessed with the quality of the pieces that arrived. You won’t regret this one! I’ve ordered the white - over 6ft long draping my love seat. The brown - for two dining chairs that I easily move around. The photos explain - enjoy.
