Dynoless Performance Testing

I've been contacted by a German firm about possibly selling their product product in the US. It is a performance measuring device that you use for road testing (NOT a dyno). Using a variety of sensors, it measures:

- HP
- Torque
- Accelleration G forces
- Braking G forces
- Engine RPM
- Wheel Revs
- Air Pressure
- Air Temp
- Humidity
- Road Resistance

It confirms to DIN 70020 standards and has been tested to be extremely accurate. Set up is simple but it does require that the user enters wheel diameter, car height and weight, fuel volume, etc...

Since it's obviously cheaper than a dyno, it would be much cheaper for the consumer to use...probably a low flat fee for a set number of runs. Being able to test braking is also a very cool feature.

Is this a service you guys would be interested in?

Maybe

That does bring something up though... where would you "run" in order for the test to take place? What speed do you have to go up to in order to get a good reading? Definitely interested

100kph. That's not very fast, but a deserted road is ideal.

62.5mph... i might be interested. approx costs?

This is just a guesstimate, but I'd say probably around $50 for 5 runs. This device doesn't have an integrated wideband, but I could always throw on an LM-1 for an extra fee.

100 kph is only ~62 mph, right? Dulles toll road's normal traffic speed is ~75mph.

Dyno gets my vote....

I'd rather have 4 pulls for $75 on a professionally calibrated machine where I can compare to other cars that have run on the same machine, instead of a device that relies on the MAP sensor I dropped several times while installing my SMIM to tell me how much HP I make. Besides, any obdII pocketlogger can give you info such a airtemps, engine load, etc.

The only thing OB2 is used for is engine RPM. Everything else uses external sensors. Your MAP sensor isn't used.

Here's a shot of the speed sensor.
