Well it doesnt cause a problem, because I use a knock light also to detect when it starts pinging.

When the light turns red and stays red for more than 5 seconds at a time, then u know when to stop

you guys crack me up!!!!!

how do u plug in a 3.5mm headphone jack into a vaccum line and hear?? just the 3.5 mm headphone jack into the vaccum line or with something else?

anyway... thanks for all ur helpful comments

You need an old vacuum amp to connect the vacuum line to the 3.5mm jack. Works a treat!

The good thing with tuning on a dyno is that you actually know how much load is being placed on the engine. It would make tuning the load tables in the ecu a lot easier. When you road tune a car the load is constantly changing eg: uphill, downhill, head-on winds or fat passengers .

Anyone want to set up a group buy for a PWRX 4wd dyno?

anywebsite for a vacuum amp?

GROUP BUY?? hahhaha.. how much would that cost?

I got mine from http://www.ampwares.com/

Also, check the for sale if theres a cheap knock light... They usually come up cheap second hand.
