I am a 15 years experience electrical field engineer, revolted with Japanese Greedy company that hide their sources and force us to buy broken stuff from crook people around the world in order to make their junk to work.
Ok, here I opened this forum after 3 years development and thousand of dollars spent for this greedy mitsubishi company that hide all their technology.
I will post here all the datasheet for this ecu, including the firmware to reflash 27c512, including any retrofit part, I will create an ecu much better than the stock ecu that this greedy company sells and does not work that we can find around crook people selling ecus.
It will include all the information related to this ecu working on same pinout way than original ECU, however chips like mh6311, they will be replaced for another easily find in order to make life of people easily ....
All the pcb, schematics, files, firmwares, they will be included on final pdf file attached to this forum, I hope all interested people are welcome, any ideas they will be really much appreciated and credits will be given on final docs noted for those people that help in this entire development.
I really will replace this 27c512 "UV" for one electronically chip eraseable as this is museum part "UV" does not use anymore on modern applications.
Here we go .... first step:
My ECU gives error on Cranckshaft position Sensor, even though I replaced it for a new one and tested the wires inside this ECU and still so it gives me the error "crankshaft "a circuit malfunction".
1 - E310A IS A PLCC44 THAT RECEIVES THE CRANKSHAFT SIGNAL AND CAMSHAFT SIGNAL FROM SENSORS ON ENGINE.
E310A
Vendor: MIT
Package Cooled: PLCC44
D/C: 04+
DescriptionAV+, BV+, CV+ - are the power connections from the hy- brid to the bus. The pins for each phase are brought out separately and must be connected together to the V+ source externally. The external wiring to these pins should be sized according to the RMS current required by the motor. These pins should be bypassed by a high quality monolithic ceramic capacitor for high frequencies and enough bulk capacitance for keeping the V+ supply from drooping. 78 µF of ceramic capacitance and 6200 µF of bulk capacitance was used in the test circuit. The voltage range on these pins is from 16 volts up to 75 volts.

Features
The E310A is a synchronous, integrated FET 1A step-down regulator with internal compensation. It operates with an input voltage range from 2.5V to 5.5V, which accommodates supplies of 3.3V, 5V, or a Li-Ion battery source. The output can be externally set from 0.8V to VIN with a resistive divider.
