Timing Tuner Works ok Now Well I tried auto tapping my timing tuner tonight,ran 2 runs with out the n2o activated,to make sure of where my timing is,Then flipped the switch with the bottle off had it set for 5 degrees of retard on the RTD switch both Base and WOT timing are at 0.Guess what my timing was the same!Boy I sure am glad I didnt just run the nitrous.So what did I do wrong?The check lights are working right.So why didnt it pull timing out?

The timing tuner alters the signal after the PCM, so it won't show up on ATAP.

No Kidding,You guys are serius?I just tought that would be the way to check it.I am sure if I retard it that much I will feel it,I hope?I will give it a try
....Thanks
....Thanks The timing tuner pulls timing while fooling the stock PCM into thinking it's still got full control of timing.
Only if you pull timing by programming will you see it on ATAP.

ahead or behind in time the spark timing in the engine is changed.
Since its also a window switch its hooked to the nitrous relay and thats what activates it.

If you need help with these things, there are pleanty of forum members to help. I have the timing tuner and it works fine. Nitrous is a great way to go fast, but with all the electronic stuff we need it can be frustrating! But when you post topic like this it can be misleading to others...
