What do you use for nitrous timing on a LS1?

Hi, I have a 2001 SS convertible. The car has been tuned with the HP Tuners software. I am adding a Zex direct port nitrous system, and I want something that will automatically retard the timing 5-6 degrees when the nitrous is armed.

The MSD 6010 controller was recommended but it says it's for LS1's with carburetors.

I have also been told this one from Accel is good.

What is everyone else using to adjust their tune on the bottle?

The lingenfelter unit is supposed to be real easy to install and has worked very well for a lot of people . A little pricey though .Im sure one of our great sponsors could get you one .

If you talk to Frost he has something for pulling timing only when the nitrous is armed. I have that, though not installed yet. Im gonna send my computer back to him again to have him tuned for it. Basically you get the best tuning if your N/A and timing pulled when nitrous is armed.

Check out "timing tuner" allows you adjust the timing. http://www.thunderracing.com/catalog...d=221&pcid=203

I use that timing tuner on my formi and love it. You can program the amount of retard that activates only when nitrous is in use. It also has a tunable delay function that helps you dial in your launch at the track so you don't blow the tires off and has programable window sw. The dely function knocked over a 10th just off my 60ft alone with consistant launches.

I just purchased HP Tuners so I'll be able to have different tunes with in a fingers reach. I'll be running mostly NA and then maybe a Nitrous tune at the track.
