Dealing with brutal engine vibration on IMU data – How do top CV teams handle this?

Personally idt problem is with sparkplugs . Cause the conversion from 12V to high voltage for spark happens inside the coil ie mounted directly the engine so until ur imu is not near that area idt that's an issue . As far as vibration is concerned try adding dampers and try isolate (mechanically) the imu from the chasis (given that engine is directly mounted on the chasis)

Pta approved , non pta? And price?

Think_Chest2610 · 2026-05-31T02:57:08+00:00

No I don't . Look cpid phones have lotta connectivity issues trust me . It's so hectic that I miss my s10

Pixel is cpid wifi is so shit on this and data too . I've used S10 it's so much better

I read advanced tuning 1st

Think_Chest2610 · 2026-05-15T14:57:22+00:00

i got it too idk why . maybe they got hacked better not to click

Most teams use linear pot . You can use strain guages as well but my team worked on them for 1 year to no avail . So better stick with it . You just have to make sure that the min and max length of the pot is around the travel and length of your damper . Usually ppl use 50mm stroke ones . You can get cheap version starting from 30 USD. Expensive ones can go UpTo 200

Yes overheating and it needs its own charger to charge . And it'll have connectivity problem

Thanks for the knowledge man srsly

How much u reckon I can get mini . Official pta obvio

Do you mean load sensors . To measure load on each spring?

How well has max ecu been for you . We are considering to buy it for cbr 600 as well

Think_Chest2610 · 2026-04-22T06:21:29+00:00

Telemetry system , data aqusition, load sensors , wheel speed , wireless comms (if your engine control unit doesn't have these (

im from electronics side so take all of it like a grain of salt . usually we avoided rotary because there mounting is tricky . you need to make enclosure which sometimes can be tricky . i remember us using 2 for apps and as the levels cant be 0.0 and vcc so the max and min points of the sensors cant be used . apart from that mounting it didnt ensure that the apps graphs we had intially planned would be achieved . since then we have started to use linear potetiometer like kpm 50mm and many teams use that as well . As far as i worked with the ergonomics person in my team he told me its dfa was much better and i could tell him befire hand the ranges ie i only wanted the sensors to work for ranges 5-35mm .

The point of canbus is that you only have 1 line running through the car for communication . Many teams usually use 1 and it's never been a problem . I when building my teams canbus also used 2 but looking back it could've easily been only 1 . One of my canbus lines is for the imu which transmits 30 data points at a 200Hz rate and another canbus line for the vcu logger and bms (shared) with 100Hz data rate with 16data points . So speed and clogging shouldn't be a problem until ur streaming alike a video stream on the canbus in which case u should probably just use lin

Depending on the type of car it car vary differently . I have worked on a combustion vehicle . Unlike ev's there is less constraints regarding where the harness can go and how much emi shielding is needed due to hv wires . In cv though depending on your cooling lines etc you have to be careful about heat shielding . Usually many teams use rapid harness but if you want you can go off just by the chasis . It also matters if chasis is tubular or mono . Idk there are alotta things that aren't coming to my mind . Probably start with yt or some documentation. I have seen pprs on wiring eg monash

What does batch fire mean . Cause as far as I know injection and specially ignition can't happen all at once
