Excuse me,Which project uses the Lin module (K-Line)? I need it to obtain data from the speed sensor from ABS.

One is the traditional injection in the intake manifold, and the other is the direct injection of gasoline into the combustion chamber. VW only does it for a few years only on fancy models in US? Toyota D-4S does this for many years now Yes, I strongly agree with your viewpoint. This is also one of...

I found a job in car modification. My boss converted its Jetta (Golf) MK2 into an EA888 engine. The EA888 has two sets of fuel injection nozzles. One is the traditional injection in the intake manifold, and the other is the direct injection of gasoline into the combustion chamber. I have the conditi...

In alphax-4chan, U1 requires to use TLS115 (C99000011264), but I only found TLS115B0LD (C540241), TLS115B0EJ (C540240), TLS115D0EJ (C540242), TLS115D0LD (C540243) produced by Infineon. This is the description of B0: https://atta.szlcsc.com/upload/public/pdf/source/20200807/C540240_87A9E1CDF961AD2327...

I have finished drawing the PCB processing drawing, and I am currently checking whether there are errors. It is known that the sensor uses separate grounding to ensure that the clock signal is consistent. I checked V33A and V5A, but the wiring diagram of Hellen-One MCU144-0.6 module shows that GND ...

In alphax-4chan, if the type of camshaft position sensor is Hall sensor, can discard one of the vr-discrete modules?Just like hellen 121vag。Because I'm not a producer, I can't guarantee that discarding any module without my knowledge will not bring any accidents.

I seem to find a mistake in the power12 module of hellen one. The original number is U410 https://github.com/rusefi\alphax-4chan-main\boards\alphax_4ch-e\board\original.top.png maybe error.png Should the red dot pointed by the arrow be diagonally opposite? It is obvious that pin 2 is not aligned wit...

When is Hellen121VAG connected to F1 jumper? Because I saw the of alphax-4chan +12V_ RAW and V12_ PERM is connected. I have known V12_ PERM is the positive pole to the battery.

One more thing, my translation software translated Raw into food that was not cooked.

You may also need to add these:
PERM
PPS
IDLE
TPS
RES
RAW
VIGN

I have determined the definition of some pins through screening. The wiki of hellen121vag shows that Passat B5 1.8T is absolutely available. This sentence may not apply to the improved Passat B5 manufactured in China. I found the circuit diagram of Passat B5 1.8T manufactured in China. Through compa...

Yes, they all use the hellen one module. But if I don't understand the principle of the hellen one module and the meaning of the pins clearly, even if I look at other boards that use the hellen one framework, I can't understand its meaning correctly. In fact, most of the problems are that the transl...

A new small question. In https://github.com/rusefi/hellen-one/blob/master/modules/power12/0.2/power12-schematic.pdf, what does the "VIGN" of V3 pin mean? What word is it abbreviated? I tried to use translation software, but I didn't get the results I wanted. Voltage IGNintion. +12 that is...

I understand the definition of the ECU pin of Santana. It is not consistent with most 80 pin EA113 engines, because Santana is an older EA113 engine. Although Shanghai Volkswagen modified it to meet higher emission standards, it is actually a very old carburetor EA113 engine. This is very unusual! ...

The original Santana b2 communication protocol is K-line, and ABS also relies on this protocol to communicate with ECU. If ECU does not support this protocol, ABS system will not be able to exchange data with ECU. It is worth mentioning that this situation lasted until 2012, because Santana B2 stopp...

Santana B2 uses 1-4 and 2-3 ignition coils at the same time. The plug of the ignition coil has only four pins. One pin is 1-4 ignition, two pins+12V, three pins are 2-3 ignition, and four pins are grounded. Can I forcibly connect 1-4,2-3 signal wires together? Just like the picture.I'm worried that ...

I apologize,My network is not very good. I have tried to upload pictures many times and failed. When I checked the Produce_DanZhi.SMT_Snapshot.Top.2582135A_Y268.SMT0220905955381.png file, I found that it does not exist, but the information on the alphax_4ch-e-schematic.pdf file points to here. Are t...

I found something missing: In alpha_4ch-e-schematic.pdf .The resistance value of R103 of SPI1 MOSI of MCU pin 135 in the file is 10K, which is in Code R103 is not found in the file alpha_4ch-e-BOM.csv Similarly, pin 133 SPI1_SCK The resistance with the code R105 and the resistance value of 10K canno...

Thank you very much. I have collected all the required hardware files (maybe) and am preparing to make a new PCB based on the original PCB size to replace the original PCB. Because I made it according to the circuit diagram of alphax-4chan, I hope it can be compatible with the firmware of alphax-4ch...

I found relevant files in github\hellen-one-master\modules\mcu144\0.6, but I don't know how to import submodules?

The result of my translation software is wrong! The incorrect translation of gerber into "footprint" and the translation of modules into "grid" is a thing of the past. Now I understand the correct meaning, that is, module design! About the 144 SCM module, I only use this path: gi...

New progress! I'm looking at alpha_ 4ch. kicad_ In the sch file, the corresponding MCU pin is not explained, otherwise I don't know which pin of the corresponding MCU, and where should I check it? thank you!

New progress! I can't find the firmware of alphax-4chan. Is it common with https://github.com/rusefi/rusefi?

Wow, it looks really complicated.

You know you can buy a pre-built one, right? It may be worth it to avoid the hassle of assembling and debugging a board yourself.

This is really a good suggestion, but I still want to DIY myself and share this process.

Can you try getting in touch with the https://rusefi.com/forum/viewtopic.php?p=45863#p45863 guy he has his custom design in China I found the 80pin PCB in the hardware folder. I still don't know how to clone the repository and sub modules. My translation software may be inaccurate, and the translat...
