does anybody have an idiots guide on how to correctly Dyno a Nissan 300 ZX TT Automatic,

 

thanks

1. Drive car to a Facility with Dynometer

2. Give them your car keys and money

3. Watch them scream its nuts off it in 3rd gear

4. Collect keys and Dynosheet results from them

not quite what i meant , do they ramp it up slowly thorough 1st and second or floor it all the way. when it get into third do they then floor the throttle , how do they prevent it from changing down etc etc

They should get it up to a speed where its happy in 3rd gear (1:1 ratio) and wont kick down, then they accelerate it hard. I've seen it done in 2nd as well where its easier to get a pull from lower rpm without kickdown, but the operator will have to alter the dyno to compensate for the ratio change or the figures will be out.

 

Autos are a pain to Dyno but its up to the Dyno operator to know how to dyno test an Automatic. Speak to them first to make sure they are confident, and if not take it elsewhere.
