Whats sensors do you guys log?
I Know these

Fuel Presure
Oil presure
Water Temp
IAT
Oil Temp
Turbo Back Presure
Egt
Boost

Anything Else ?

 

VSS, Rear Wheel Speed, pre-intercooler pressure, after intercooler pressure, A/F

 

In addition to the OP's:
Front speed
Rear speed
Air pre IC
Air post IC
Water pre IC
Water post IC
Coolant pressure
Turbo inlet air temp
Turbo inlet air pressure
Lateral force
Suspension travel front and rear
Brake pressure front
Lambda
EGT x4

 

Good thing they give you an hour between rounds.

 

I don't plan to look at all that data between rounds. Just the stuff that matters. I want to learn the most from the car.

 

I just thought that was comical. Brake pressure?

 

Brake pressure is common. Although it's usually on the non driven wheels so you know how much pressure to stage with and for burnout.

 

Alot of what he listed is not something you look at every round, it is nice to have. Data is everything. You can always have a lot of data, but when you do not have enough data, thats when you get into problems when you have something you can not figure out with limited data. If you have no data, you are just guessing a lot of time.

Hope that makes sense. Log as much as you can, that your system will allow. Just log what you think is important first.

 

Damm i knew people where doing alot, but damm brakes also..

 

As stated above, data is everything when you're trying to figure out issues. I plan on using every available port on the M400, then adding the 888 for everything i've forgotten, lol.

 

^^^ The M400 run out of channels in a hurry! lol certain things i put as a stand alone so i did not use up the more appropriate ecu channels

 

You can never have enough inputs. No matter how many you have you'll always find a way to use them all up.

I personally like using my ecu for all tuning related inputs and use a dash logger for everything else.

 

Rear speed and front speed.....why both

 

well obviously its easy to log front speed, but the rears so you can see when exactly the fronts spin.

 

What's the best way to log rear speed? What is needed? Alway wanted to ask for more info on that subject but never have. I'm looking into loggging more things for 2011 so hoping to learn a lot

 

you can use the rear abs sensor, or make your own.

 

Logging a million sensor dont matter if you dont know what to do with the data......

 

Exactly, some small timer like myself wouldn't know what to do with most of that data. What issues are y'all talking about over coming with all of that data?

 

its simple u do passes & when data starts drifting from the norm u can finds things stating to arise before they become issues,
or find ways to fix issues ending in more power.. the list goes on...

the dyno is just the beginning stage of TUNING a car... the real tuning is done at the track with data.. then hours looking at the data post race reading & making changes on & off the track...

 

Everyone keeps saying that, but where can you go for reference on how to go about setting it up in detail

 

The set up I have is a hall effect sensor with cobalt magnets machined into place on the rear wheel.

 

input shaft rpm in addition to the others listed
