4) aliexpress 32839361268 is interesting - I like 48 pins, but I have no idea what is the side of this box - is it much smaller or similar? Also nice if it's really real molex or compatible molex, not some unknown connector. Is it a problem that it has no metal parts i.e. it would not be a heat sin...

I can help you with PCB. It would be better if it was just a little larger, so you at least can have footprints for H-bridge and other stuff. How about something like this? 80pin-ECU-Aluminum-Enclosure-Box-with-Molex-32-48-pin-molex-PCB-male-female-ECU or https://www.aliexpress.com/item/1-sets-kits-...

I placed all needed components for a 4 cylinder just to see how compact/few components it get.

It's got
14 Analog
8 Digital
E-Throttle
CAN, VR etc
60 Pin TE AMP Superseal
70 x 60 mm

Add a TLE8110ED, and it's enough for 8 cylinder

The TLE7209 H-Bridges are connected directly to the MCU. Wont it work? Do not know. My question was if we expect TLE8888 to work as well or not. It shoud be able to, but I dont know how easy it is to implement. I have not connected them to anything. I spoke to a guy at Infineon a time ago, and he c...

2x TLE7209 H-bridge drivers for E-Throttle 16x Analog Inputs TLE8888-1QK For Power supply and rest of the outputs Do you use any op-amps on analog inputs - which part number do you use? Do you have half-bridges wired? Do you expect TLE8888 itself to be able to drive one or two E-Throttles? The anal...

If you all donate a little, russian soon have his microscope :-) Thank you! If you all donate a lot, russian simply retires :) That would be the absolute best, but open source usually dont make people rich :-) Come on folks, we now just need 135$ to reach the goal:) Post donations here! #microscope...

I just donated $50.

This is the one you want!

Let's start to donate for russian to get one!?

Dont think it's from heat.

I have heated IC's so they are almost rubber, and never destroyed any.

What are the circuit(s) that are connected outside of the ECU to each of these ADC's? If you know the circuit, then you can optimize the input circuit. For example, it is common your 5V will go to a sensor, then back to the ECU which has a pull down resistor. With a circuit like that you are reason...

A little update: The F767 are working fine, and a lot have been sorted out. For the TLE8888, the outputs are still not working as they need SPI. Boards are sent off to russian and arrives today, so I guess it's up and running soon :-) russian will probably post some updates and pictures here as well.

I think they would be okay with it. We probably need to change some of the names, VID, PID's etc. but most work are already done. No need to reinvent the wheel :-) I think I read it somewhere they are moving on to use DFU instead. That makes more sense for a drone, but for a ECU that often are a lit...

You also see if it's GDI from what ECU they use.

Most VAG from 2005- are GDI.

From the link kb1gtt posted:


Engine Management: Bosch MED 17 from Bosch MED 9


Bosch Motronic E-Throttle and Bosch Motronic E-Throttle Direct Injection

I dont have any GDI Engine now.

The MCU already has rail clamping diodes. Your 2.7k ohms will negate the 10k. AKA a surge will pass through your 2.7k instead of your 10k. This will likely cause the 5V to go higher then 5V. The PESD5V2S2UT leaks 0.14uA, which is likely to skew your readings. Keep in mind 5V/(10k + 15k) = 200uA. Th...

Yes. At least for me.

Thanks!

I can live with these circuits

The arrays really make it very compact.

Also a lot of those Bias/Pull-downs goes away. I made one circuit and copied it.

Does this look correct?

Something like this? Analogs.jpg Yes. But pull-ups and pull-down are after divider. If you are going to have some NTC, you need to move pull-ups/downs before dividers. Or you pull up will be 2.7 K + 10K that is too much for 1K NTC. They are before. IN means in to MCU. The whole schematic: Analogs.j...

Something like this?

Injecting current through pin clamp diodes can reduce accuracy of whole ADC. I would suggest to use external protection diode with breakdown voltage less than maximum input voltage for adc. Can you explain a little more? What components to remove and what components I should place where :-) I am fa...

This is what I have now.

Dont mind the resistor values. They are just for footprints for optional pull up/downs.

Thanks for your input Yes, what I mean with bulletproof is shortage to max 12-14v or gnd by wrong wiring Does the MCU survive 12v as long as there are enough series resistance? I see the Bosch ECU's only have a 33k array in series before MCU and nothing else. I have used 10K and 15k voltage dividers...

Is https://github.com/PX4/Bootloader showing that a great bootloader with USB is a project by itself?

Would be great if it can be used. I have no idea how this copyright works.

I have tested it on a F4, and can confirm it works flawless from their software.

All at native USB.

You've also mentioned ADS7957? What problem are we trying to solve? We have a lot of great boards but not enough software developers to even use the existing boards up to potential. For my own use it's enough with just voltage divider arrays. But for a ECU to sell, I need to have some overvoltage p...

A tip for you, and anyone else that worries about solderbridges. Haven't you heard about Desoldering Braid? I have used that for as long I can remember, and it removes bridges and exessive tin from whatever. I usually use the pull method for IC's. You apply tin at the first pins, and just pull the i...

Also, I think I have messed up a F4 somehow.

Everything works fine, exept DFU.
It keeps trying to enumerate over and over when I keep Boot0 high.

How can I find out what's wrong?

Can we make a function that jumps to DFU mode triggered by a software-button?

Does anyone know how often do we need MAP and TPS analog inputs? https://rusefi.com/forum/viewtopic.php?f=4&t=1516 talks about"Kinetis MKE1xF as analog/trigger input software controller" while technically we might be able to run the whole rusEfi on Kinetis MKE1xF. At the moment Kineti...

As topic I am looking for a solution for the ADC's. I want as less components as nessecary, but need to be overvoltage protected. I have a Link G4+ (Link are well known for its bulletproof inputs/outputs) I opened it, and find it's got no massive circuits. Link.jpg I find it has several analog switc...

I'll post the update for the bootloader code soon...

Would be great!!

Can you make a config for F7?

Does it work from Tunerstudio with a software interrupt?

OTG port?
