hey guys,iv'e been reading about people getting a nitrous tune when running nitrous.when i got my 125 wet shot i went with the tr6 plugs and my tuner took 4 degrees of timing out.would this be considered a nitrous tune?i'm getting 11.5 on my wideband on nitrous and 12.8 n/a.i asked him about having to change shift points and he said they will be ok on the bottle and i haven't hit the limiter yet.would there anything else to do or am i ok. thanks

 

Make a full pass on new plugs and take them out and see if they look good. do a search on plug reading for more info. You can see if it's lean/rich and if it needs more or less timing by the marks and color of the plug.

I pull 5 on a 150 hit with colder plugs. My A/F reading are identical to yours. 11.5 on the spray from start to finish. 12.4:1-13:1 on motor.

 

thanks autorock

 

You're gonna want a window switch if you don't have one. The last thing you want to do is bounce it off the limiter on nitrous.

 

ok thanks zeus.appreciate it

 

If you are going to do this to read the plugs you need to make sure that as soon as you are done with the pass you need to kill the car and pull the plugs before you drive it back to the pit's. Just that little amount of driving on them will wash away any marking by the time you reach the pit area.
