What if I told you... that datalog graph is only 14psi in 3rd gear?

[johan]

Never mind the fact that you put the code into the MoTeC in the first place...

THEN I'D SAY IT'S GARBAGE.

It just has to be repeatable the actual accuracy isn't important as long as the repeatable data is consistent.
Talk about a easy way to tune with out a dyno. Talk about using the data to setup traction control or other mapping features. This is extremely promising

I actually dial the TC in using the accel data from my IMU. Same with launching.

However this logic is super repeatable -- stick to the same road, same direction, etc. and it'll be the same results every hit (baring conditions stay the same). Once you start to hit wheel spin (or just too much slip) then the "effective power" will flat line and/or just drop off (as you're not longer putting it to use in accelerating the vehicle), so for fine tuning and some road tuning on the road -- absolutely useful.

If something's fishy with your motor/setup (boost leak, etc) the power output will drop too, so it'll show up as well. Once you have the TC dialed in and actually get on the TC it'll obviously hold the vehicle at a specific power output (as more spins the tire).

We haven't setup my traction control yet but I'm really excited to do it eventually. Rolling launch as well. Going to make a few hits down the track without it first to collect some data.

You should get on it, it works amazing

The package motec sells doesn't include any rolling launch logic. It's got a generic Anti Lag class, but it doesn't even come close to how my rolling launch works

Yeah my buddy built the package on mine. Actually waiting for the final license to get back from motec so I can flash my actual ecu and stop using the m1 developer ecu. He's a motec nut, Obsidian Motorsport

Awesome!

VitViper,
The logic behind this is solid, I am super stoked to see where this goes. NOW if you could just do the same with ECUTEK......lol

You can... the logic is similar to the torque graphing "eDYno" software I wrote (much better than Virtual Dyno as I don't use their graph smoothing algorithm lol)... the limitation with the software dynos is they go off acceleration measured off driven wheel speeds (engine rpm)... which is susceptible to a lot of fluctuation with wheel slip (once you make enough power) and I've found the "faster" your car is the harder it is to get a clean graph (IE, 700whp+ cars accelerate so fast the sample rate of most datalogers suck and driven speed usually has a lot of slip).

Currently I have the ECU sampling and calculating at 50hz, which should be more than plenty... but if not I can certainly run it faster

Obviously you can skew the results if you want to though.. grab some gears down a big down hill grade... lol
