jecs ecu???

[josephg15]

i got a jdm ecu with my sr20det swap and the ecu had a toggle switch...i opened it up and there was jecs chips in side...has anyone heard of jecs? and the toggle switch can be switched to N or T (N-T) there is also a dial that you have to use a tiny screw driver to turn left or right...maybe to turn something up or down...not too sure i am not able to post pics on the website...but i can send you a pic if you have any idea what this is about...thanks

JECS is the stock chip manufacturer, all Nissan ECU's probably have JECS microprocessors.

the toggle switch is probably to run to different maps for different boost settings. good luck trying to figure that out though
