TMS374 ECU programmer TMS374 MCU ECU decoder

TMS374 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.Connection diagram:+ : 12v DC- : GNDS : signal wireManual: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.TMS-374 Decoder ECU infoThe sweeper should work with the following ECUs:Renault SIEMENS Fenix 3 and 5Renault Megane 1400cc 8vRenault Megane 1600cc 8vRenault Megane 2000cc 8vRenault Megane 2000cc 16VRenault Megane Scenic 1400cc 8vRenault Megane Scenic 1600cc 8vRenault Megane Scenic 2000cc 8vRenault Sefrane 2000cc 16VRenault Laguna 2000cc 8vRenault Laguna 2000cc 16vRenault Espace 2000cc 8vRenault SAGEM SAFIR 1 and 2Renault Clio 1200cc 8VRenault Clio 1400cc 8VRenault Clio 1600cc 8VRenault Clio 2000cc 16V WilliamsRenault Laguna 1800cc 8VRenault Laguna 2000cc 8VRenault Laguna 1800cc 16VRenault Laguna 2000cc 16VRenault Twingo 1200cc 8VNOTE: 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.Sagem SL96 PsaPeugeot 306 1400cc 8VPeugeot 306 1600cc 16VPeugeot 306 1800 16VPeugeot Ranch 1400 8VCitroen Berlingo 1400cc 8VCitroen Xrara 1400cc 8VCitroen Xrara 1800cc 16VDAEWOO SIEMENSDaewoo Matiz 800ccHYUNDAI SIEMENSHyundai Coupe 1600cc 16VHyundai Coupe 2000cc 16VKIA SIEMENSKia Rio 1300 16VKia Rio 1500 16VMAGNETI MARELLI1AP20, 1AP40, 1AP41, 1AP43, 1AP80, 1AP81, 1AP83 1AP90,Citroen Berlingo 1800cc 8VCitroen Saxo 1400cc 8VCitroen Saxo 1600cc 16VCitroen Xara 1400cc 8VCitroen Xara 1800cc 8VCitroen Xara 2000cc 16VCitroen ZX 1400cc 8VPeugeot 106 1400cc 8VPeugeot 106 1600cc 8VPeugeot 106 1600cc 16VPeugeot 206 1100cc 8VPeugeot 206 1400cc 8VPeugeot 306 1400cc 8VPeugeot 306 1600cc 8VPeugeot 306 1800cc 8VPeugeot 405 1800cc 8VPeugeot 406 1800cc 8VPeugeot Partner 1800 8VProcedure: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.
