Re: rusEfi own wide band controller board add-on using CJ125

The part number is 30615. In our country, we have many local chip stores, because repairing of commercial ECUs is very popular. I ordered 30615 from one of this stores. But the gateway of these chips is chinese distributors(www.1688.com). My schematic/Code is same as RUSEFI with some modifications....

Future electronics shows 11 in lqfp32. Ill order there. Only place I can find elsewhere is from china auction sites. I try to avoid them when It comes to ic's.
The part number for future would be 0272240103

I'm using LQFP32 pakage without any problem!
I'm assuming your code and schematic is the same as what rusefi has on their github. Would you also by chance know the part number of the chip you ordered and where you ordered it from?

Re: rusEfi own wide band controller board add-on using CJ125

I'm facing some issues with the CJ125 chip. All the SPI communications yield the right results, the Lambda readings are correct (only tested in open air) but the temperature output from the chip seems stuck at ~0.86 V regardless of how hot or cold the sensor is. Tried 4 different chips but all of th...

Re: rusEfi own wide band controller board add-on using CJ125

In regards to the topic of board redesign, why was the SOIC24 package of the CJ125 chip chosen instead of the LQFP32? Both the package sizes seem readily available on FutureElectronics and the LQFP32 is half the size of the SOIC24.
