Ford J1850 PWM Module Reprogramming with SVCI J2534

Obdii365.com received new feedback from customer:  ” I can set reprogramming voltage to 18V on PIN 13 and do reprogramming for a Ford J1850 PWM vehicle using the SVCI J2534 passthru adapter.  This is just as expected. ”

So is it worth buying the j2534 cable?

What’s good of svci j2534?

• Works with bunch of manufacturer’s software, like Ford’s IDS, Mazda IDS, FDRS, Toyota TIS, JLR SDD, ELMconfig, Forscan etc.
•  Works with official latest ids software
• Online software & firmware update
•  Installation is very easy with the included loader
• Cheap

What’s bad of svci j2534?

• Sometimes it is instable and sometimes disconnect from car.
•  It will not program older vehicles (seemed has been fixed in new upgrade).  for the older ones you need the vcm2.

In sum, this device pays for itself.
