The stock RE ECU is around the same as well from what I heard a service center quote.

Awesome to know that.
I'm quite familiar with the concept of FSAE, having been active in my college team as well

I remember using a Yamaha R6 engine, and later a Honda CBR 600cc engine.

Would be great to know more.

Cheers,

Before giving up on the replacement ECU, with the test wire grounded, power the ECU off.
With the ECU powered up when connecting the test wire to ground, it may not recognize it.

Power the ECU back up and note if the code blinking begins.

I think the test wire ground is ECU terminal #20. My diagram isn't clear what #20's purpose is but it is clearly a disconnected grounding point during normal operation.

Because the replacement ECU was deemed 'no good' it may not function regardless of what you do but it's worth a try.

I did exactly like you said, removed the power, grounded the test lead, and then powered it up. the MI lamp remained continuously on.
I am going to the service centre today to get the ECU tested and flashed.

Also, it wasn't any RE mechanic or engineer who diagnosed the ECU and declared it faulty. So I guess it might still work.

I think that's a cognizable office under IPC

Here is the Poor Keihin ECU
Sorry for bad quality pics
The price quoted by the dealer is Rs. 8700

The black rubber like material took a long time to get off
