Thanks for the information !! I didn't think about it, looks like there is a 160Hz input filter

I think the MRE is limited by the INI file.

I tune my INI file in order to add AV2 as trigger input, and it looks to work fine.

I am sure it is possible to use any AV input for 5V VSS input.

If your VSS signal is VR signal (sine wave) you need an external VR conditioner before MRE.

I finally receive the little boards :D :D IMG_20201224_124835.jpg But it isn't a success :roll: I made a wrong wiring with capacitors before resistors in input, TV5 before 10K resistors and 0.00V threshold. Actually, the crank signal looks fine, but my one tooth cam is really noisy, I had to change ...

Hum, I know that STM32 is 5V tolerant only for Digital in. But canbus is sort of digital. :roll: I don't try it, because I don't want to kill the STM32. But I have a second board with no through hole components and plug. I will try canbus on it ! :D :D If it don't work, I will try 3.3v soldering on ...

Are you sure about the idle valve ? Did you check it ? On NA it is really common a bad idle valve.

For the 20kPa, you can set the same value that 30kPa and keep 20kPa line. You can tune it later.

In the log, you have trigger errors. There is a problem somewhere, the cam sensor wire is fine ? Have you set the 20kPa in fuel VE table ? This line looks set too low to me, but I can be wrong. Maybe try to set the 20kPa line like 30kPa. But for sure, we need the logs of the deceleration in order to...

Just for information. This board is a big fail. I put 5v for VIO on the canbus chip... The canbus can't be use, the stm32 is 5V tolerant only for digital input. :oops: I have set the battery input voltage on a non ADC pins :roll: And lot of shits like that... The EGT chip gives nothing, it is a fata...

Hello,

did you try the EGT input ? If yes, did it work ?

Thanks,

Here is a more advanced board. I go with OP07 and a LM393. Discrete Sexyjpg.jpg Schematic_Discrete_2020-12-06_03-03-06.png Discrete Price.jpg The price is for 5 boards with components, pretty good, the price of 5 MAX9924 chips. (that is only single channel) I think I will order 5 and try it. I have ...

Thanks I realise after lol, the habit from Slack I wanted to upload the asc files, but I had to zip it.

I want to try the OP07 from texas instrument, I don't succeed in using it in LTspice because of lack of inputs, there is internal offset tuning, and it is a basic part !

I have it on my 1JZ non VVTi, I have a single cam tooth, I have to put 10K inline and 1k in parallel.

I tested the simulation with LTspice, it is a bit difficult to find the components from jlc-smt, so I use a universal OPamp, I think the MCP6002 will act the same. Here it is : 100mV.jpg 2V 50K.jpg 2V 200K.jpg 100V.jpg The tests are with 50K and 200K on the mosfet, the 200K allows 100mV detection, s...

Oups ! sorry about it.

I never see that simulations are possible, that's crazy !!!

I will take a look

I don't know for differential input, on megasquirt you only have the positive of the signal, and there is noise !

I give a try, in basic part, with a board that I can install instead of my MAX9926 board. I go for through hole trimmer, so they aren't in the BOM for JLC, everything else is okay. I go with MCP6002, I abolutely not sure about it... Some say it works well, and it is basic. discrete price.jpg Here is...

Wow ! Thanks :D :D :D It isn't possible to have software VR ? I mean, a small amp for converting 0-150v into 0-3.3v and tune trigger and hysteris by software. Maybe a standalone stm32 ? I think it is doable for Knock sensing, with an ADC microphone. Mck117 is right, discrete from MS3 < LM1815 < NCV ...

Sorry... I take a look to Kicad, and I just can't. I can do it with easyEDA if you want. I think that MMBT5401 can certainly replace ZTX553, I don't think 2A is usefull for VR and 150v probably better. The LM2904DR2G can certainly replace MC34072 who is basic part. Old megasquirt used LM2904. The on...

The megasquirt version on Kicad ? Lol, I really don't like Kicad, it is a pain in the ass without a mouse. But I want to give a try, and it is an occasion. I actually have a independant VR connector, it is a good thing for testing. I know than JBperf has a board before the MAX9926. I actualy don't h...

It works well in megasquirt, there is two adjustable pots by VR channel.



But maybe it works with +3.3v for safety ?

Yeah ! That's already send from JLC. And I have the majority of the parts "through holes", but I don't have TPIC8101 for now. In fact, it is more a "Full Basic JLC with through holes components" The MAX9926 is a board from speeduino, I have already done it with my microrusefi, bu...

That's right ! Absolutely no problem for sequential COP on 6 cylinders on microrusefi, I don't want wasted spark, it is more stress for coils, and they are limited for my use. But I will try full sequential for injectors, I can't test the outputs for now, but I don't know why it will be wrong at low...

What is the ultra low cost of the BlitzboxBL49sp ?! I am curious.
MAX9926 and CJ125 aren't soldered by JLC.

Why do you want so much CDI ignition coils ? The RusEFI ECU actually use the TC4427 for ignition control, it can be use in 5V or 12v and is really powerfull. It can control high impedance COP from volkswagen groups, like R8 coils, something that megasquirt, or VEMS, can't do (and a lot more) Some sp...

I take a look to the 0.5.3 corrected PNG, and it looks like every thing is populated on the top side, except R86, so I can use AV6 for one injector, through TLE_OUT12_PRE in tuner studio. Am I right ? Do I need to remove R84 from the PCB if I want to use AV8 for another injector ? Or is it OK ? Than...

Hello ! I just received my microRusEFI, I am really happy because it is a 0.5.3, with 2 VNLD5090 on it. But I am really confuse about it... I don't know how to use it. I take a look at the 0.5.2 schematics and it looks like AV8 and AV9 can be use for them ? I find the R86 unpopulated, look to be for...

I am a little confused about PL2303SA , does the STM32 doesn't have onboard usb ? The tacho out can be taken from smart coils. No need of more than 2 high side. It's a funny board, but why put energy in it ? For price ? And on paper, there isn't a lot of difference between speeduino and RusEFI. One ...

For sure, it is a really common "smart" COP.

OK I was curious about it.

So it's more a standalone than a piggyback for the engine control part.
It's a really cool project.

Thanks, AndreyB for answer

I am very confused. There are three kinds of signals: analog inputs - totally not 5v tolerant digital inputs - kind of OK to feed 5v digital outputs - you would only output 3v so which of those do you need when and why? reminder that we have two non stm32 platforms available on rusEFI - Kinetis and...

The goal is dash control (speedo, tacho and boost gauge) with additional sensors, like EGT and knock. I go for basic and through hole because I am not sure about me, if it's fine, I can change the BOM and pick and place for more or less options. The problem stays the 2 boards to buy. Actually I pay ...
