I cant just solder it directly to P36? I wont pin it into the harness, just solder it directly to the board.

Okey, I need help connecting Analog Input from AEM-X Series UEGO with LSU 4.9 into the board. I have already been informed that I cannot wire the AEM´s 0-5v analog signal to the WBO. I see that there is extension pads on this board, but I cannot for the life of me figure out what pin to solder it to...

I tried the ECU today. And now both coils gives spark. I even got the car to run for a few seconds! Success in replacing the driver!

Yes https://octopart.com/search?q=ISL9V3040S3S is the correct chip - that's now documented on https://github.com/rusefi/rusefi/wiki/Hellen-128-Mercedes#spare-parts Let's not discuss M104 on "Burned Ignition driver mosfet" thread. Maybe existing M104 thread would be a better place for M104...

I am looking to order a few IGBTS. https://www.mfgchips.se/products/AMI-Semiconductor-ON-Semiconductor/ISL9V3040S3S?fbclid=IwAR0sgdbUYbrBE1nY3ZpxI2k0Lr-w9yh8rNDcz4aii8Ets38qJDX2ReX8piU These are the correct ones yes? I can consult a close radio shop to do the soldering in case I can't do it myself (...

Well, I am not into board building at all, so my knowledge is limited. But I see that its full product number is ISL9V3040S3S. And some digging I see that its just a ignition driver. Edit: all the fuses are in shape, none has blown. All resistors going to the ignition are fine as well. I think I got...

BTW what mosfet is the injector driver one? I dont think I got any of the injectors to fire even once even before the burned IGBT.

Is it the one with lifted leads?

So this seems to be an issue of the IGBT drivers being on 100% due to the inverted setting. This will have surely cooked them and probably hot enough to melt that solder joint. It's possible they are now shorted to ground and causing issue elsewhere. First step is going to be removing those IGBTs a...

We have scary PCB discoloration We have lifted IGBT lead. And worst you say this does not connect to PC? That's the worst part. I would focus on this. Unless you have USB communication you have a paperweight. Please post pictures of the MCU area. I have one board in stock I can sell discounted with...

Short story: programmed it to work with TB, Pedal, and enabled starter via firmware update and soldered P5 to P35 and P31, starter working correctly without failure. Benched spark and both work, but I thought the spark order felt incorrect. Accidentally set ignition setting on spark to inverted defa...

can you provide the specific lift and duration of the cams for pre/post enignes? We didn't do much more than measure lobe height and somewhat lobe separation. However the facelift intake camshaft has 1mm more lift measuring the lobes than the prefacelift one. We got some great compression numbers f...

Hello, owner of a nice old merc with a 111.975 atm, soon to be 111.982 with rods and ported and worked head and totally refreshed engine. My old C230k has had it´s issues with tuning, and it's started to hinder my progress on building the m111 to what I want. My current build is: Rennsport SMF 7.6k...
