How to change wideband input port
Hello,
First of all please don't hit me in the head, maybe this was asked before but I couldn't find it. (i have a lack of forum experience)
For people with time on their hands, the story goes like this: I bought an abandoned turbo project left in "kinda works" state. ( Car description : 1.6 l `92 NA , TD-04 turbo, manual boost control, MSLabs MSPNP 2 Base 9093, AEM Wideband, Rx8 yellow injectors): Being a total noob, I plugged the cable into a laptop with TS trying to see gauges, and fuel tables (my nose told me the car was running waay rich) but discovered that no matter what I do, the AFR gauge won't move. Soon I discovered the MS was "a bit fried" in the sense of the previous owner forgot to unplug STSIGN fuse, which was quickly and easily repaired, and that everything was well with the 0-5V AFR signal coming from the wideband controller until it entered the MC9S12C32 microcontroller . I am not able to replace a microcontroller, nor I can program it, so I plugged the signal in SpareADC1 on J2 pin 17. Now I can see AFR in Tunerstudio only from 2nd ego sensor port (by choosing dual wideband). How can I get the signal from spareADC on 1st ego Sensor port?
TL;DR : I need to run AEM wideband signal on SPAREADC1 - how can I get the signal on 1st EGO sensor port?
Thanks!

Your post has been approved to publish. Hopefully someone more familiar with the MS2 will join in. Have you tried contacting Reverent (MSLABS) directly?
He's in the vendor's section of our forum and he has an email address posted somewhere there.
