This is my interface.
Witch resistor must be removed?

Hola!
I am trying to access to body in a alfa 147 1.6 twinspark 2004. I have an Elm327 wifi interface and can't find the famous 121ohms resistor I am supposed to remove.
Resistance between pins 6 and 14 is 50kohms (according to my multimeter).
Board is so so tiny!

Hello, I have the same PCB, have you got to know what is the resistance that needs to be removed?

hello, I received an elm327 but it's been modified for Ford and Mazda, could I change something to make it work for Fiat and alfa Romeo? I've managed to connect it to the Fiat but only on the engine module, can something be done to access other modules?

Hi guys! Greetins from Brazil!
Here I purchased one interface with "PIC" chip. Can somebody help me, about wich resistor can I remove from my board? (I need to read the CAN, align PROXI and I cant!) Pics below... My car is one Fiat Stilo Abarth 2.4 20V 170cv. Thanks in Advance!!!








There is! Any help will be much appreciated! Mine board got the "PIC" chip.

Thank you guys!!

Your ELM327 works only with OBD-2 protocol
You need to buy ELM327 on a PIC chip

Despite the color, mine board got the PIC chipset and a lot of resistors... Only the number 1 removed. Dont read my Fiat Stilo CAN system...
Any help will be very very appreciated. Thanks!
