Something happened with ECU on my drag car

Post by ItaloManyak »

I found one damaged item:

the inscription on the casing G6 07

Help identify what it is and what it can be replaced?
The new control unit is very expensive. And my car is not moving for a year :cry:

What is the name/model of the ECU? What is the large chip next to this? is it some add-on board mounted vertically?

The large chip is LM2901

No,I do not remember exactly, but it's module output may be as injectors and other loads.

Making a schematic can often help identify what it is, I might guess it's a transistor of some sorts, or perhaps a diode.

There are web pages that list chips via markings, see these examples.
http://www.markingcode.com.cn/en/search/index.asp
http://www.s-manuals.com/smd/g6

This produced this page, but you probably do not have that many regulators on this board, so I do not think to be your chip. A schematic would help determine it's not a regulator. More searching might find it.

The second pin SOT23-5 is a ground of ECU.
I have several versions
s-809019CLMC
EUP7965
This is very suitable according to the schematic:
EUP7965-25VIR1 Pinout, Pinouts

EUP7965-25VIR1 Application circuits

I unsolder a good one.
How to check it? It may be included in any kind of diagram or apply voltage?

What is the difference between EUP7965-15VIR1, EUP7965-18VIR1, EUP7965-25VIR1 and etc? Can i use everyone of this?
