Re: F103 Wideband Controller
Maybe a bit premature, but... Does the f103 have enough pins left to do a dual sensor setup? Have we determined if it has the processing power? I can work on the schematic and pcb layout of it's feasible. I would think some consolidation could be done as well.

Could this be a substitute? Decent availability, at least for the moment. Cheap enough, too.

Re: Injector lag and how to mesure accurately with RUSEFI
Great information. Method sounds very repeatable. I would not be surprised to see packages show up in your mailbox with various injectors in them asking you to repeat your findings for different vehicles...

Re: Dual Channel wbO2, no ASIC
Board re-design is in progress utilizing a different (smaller) connector. I am looking at the JAE MX23A18NF1 part. It is almost 10mm smaller length and width. Parts have been ordered for fitment testing. They are very attractive price-wise from AliExpress. MX23A18NF1 MX23A18SF1 18 Pin/Way ECU Standa...

Re: Wideband Controller: Fully Custom, no ASIC!
Could it be tolerance errors accumulating in one or more resistors? Noise in the op-amp? Non-linearity in the STM ADC?

Re: 94 Ford Taurus SHO
So this pile of parts keeps getting bigger. I'm going to have to make a spreadsheet just to keep up with replacement part numbers when things eventually fail. Building a new ECU wasn't ambitious enough, so I'm building a new engine harness as well. Gives me the opportunity to eliminate splices and c...

Re: Dual Channel wbO2, no ASIC
After further investigation, the front-to-back form doesn't really seem practical. The connector I selected is over 40mm wide and the module is roughly 25mm square.

Another layout I'm going to make a board for is two modules in line with the connector. Some people may like the form factor better.

After much delay, I see the panel mount USB port will require modifying the footprint and placement on the board.

All files have been merged to main.
Main concern is fitment of the modules side by side.

Made some minor tweaks to the pcb layout. Adjusted some track sizes and added ground fill to the front side. Any insight or correction before a prototype is ordered?

Re: Dual Channel wbO2, no ASIC
I saw where the latest firmware has the ability to program the rusEFI O2 sensor controller. How would that work with two modules? Plug them in one at a time? Maybe an option can be added to set the controller ID for sensor one and sensor two before pressing the update firmware button?

Re: 94 Ford Taurus SHO
I am not using any of the thermocouples. PA8 selected for VSS input, no errors. GPPWM configured for RPM activated output. Added bonus: the GPPWM is a 3d table so I can configure this output to respond to TPS percentage as well as RPM. OEM design would never do this.
