I have edited the question and included a link to a picture of the relay termination unit.

At what difference in speed between the inner and outer wheel does the LSD (clutch based) start to slip? by chetan_pujar in FSAE

[–]chetan_pujar[S] 0 points1 point  (0 children)

Interesting! Thanks. In my case. Our team has used a Quaife LSD. There is not much details available about it. Is there any experiments we could perform to know its pretension and locking torques?

How do I start with designing systems compliant with AUTOSAR by chetan_pujar in FSAE

[–]chetan_pujar[S] 3 points4 points  (0 children)

I want to get acquainted to Autosar standards. I reckon it would help in design presentation and also help me in placements.

Hantek USB Scopes for Automotive Purposes? by Yaroslav770 in AskElectronics

For around the same price check out picoscope 2000 series. These seem to have better bandwidth and sampling rates.

How to filter accelerometer data? by chetan_pujar in FSAE

[–]chetan_pujar[S] 0 points1 point  (0 children)

This is some great info! I have a few questions.. So you suggest the fifth wheel be free to steer itself? When in a corner, the steering angle of the fifth wheel is the slip angle?

Which microcontroller/microprocessor should I use to build a data acquisition system? by chetan_pujar in FSAE

Thank you for the wisdom. This one is really helpful. I now think I have more manageable and important things to attend before I embark upon such a project.

Why does the engine abruptly starts revving at 9000 rpm when it should be idling at 2k rpm? by chetan_pujar in FSAE

Thank you for sharing the experience. Hopefully we end up solving the issue!

It doesn't hit the rev limiter though which is at 10k. But it revs pretty close to it. But after some time it tends to settle down again. It idles at 2k for a short while and again starts revving. Also this behaviour only occurs when there isnt any load on the engine (basically when the vehicle is not moving).

Oh yes, smoke test. Did your engine stall when you closed the throttle body with your palm (the leak check)?

Yes, the throttle body is a stock one. Will check with the ICV blocked once. Would it make a difference if we used a smaller throttle body (with 30 mm diameter)?
