I currently have a wet 150 setup...I had it tuned for all out nitrouse performance so we pulled timing...Is there a program like tunercat that i could have a tune for street use...via advanced timing...i have a lab top and was wondering if i could just hook it up in there and switch it when i need it...like at the track or such....all help appreciated

 

Yes Tune Cats, HP Tuners, LS1 edit and a few others can let you do this

 

It wouldnt be hard would it??As long as your tune is already set your just upload it into your pcm right?

 

Thats right. Hook cables up, download/upload and go.

 

Ok...why does everyone I talk to seem to make a "on the fly" switch that you can use only for LS1 cars?? Can you guys clue me in on anyone who makes this for LT1 cars?

 

how about a timing tuner?

 

I have not done this yet, but EFI Live Commercial lets you use a Custom OS that enables the Valet mode in the PCM. You can use a toggle that grounds the valet mode and it will default to custom tables for Nitrous (or actual Valet) use. So you can have your NA tune, and when you wanted your nitrous tune, enable the valet mode and your nitrous tune would become enabled.

I am eventually going to work my way to that, for now I am just learning how to tune LOL.

Chad @ GLMS (Black02SS) can give you more details as well as TAQuickness.

To be honest is it really worth the HUNDRED's of dollars in software to set it up?


Ive been spraying a 150 wet shot through a standard NX Shark Nozzle for Months. I have 2 degrees of timing taken out which is MAYBE 5-7rwhp. Hardly anything you will notice...if you have a good tuner they should know that you dont need more then 2-3 degrees of timing pulled, especially for a wet kit.

 

Unless you have had timing added, you really don'r need to pull any. Now if you were dry and wanted timing pulled you could do it all in the same tune and only have timing pulled while spraying, then no up/down loading. But then again even on a dry 150 no timing pull is needed if a/f is correct.

At WOT doesn't it already pull like 4 degrees of timing
