Whats the process of pulling timing and how do you do it?

 

you can use http://www.msdignition.com/ignition_18_6520.htm

i want to get one of these for my LT1 car

 

Whatever you do, don't go this way...for I still don't know the answer!

I have the 6al/dig window switch/8982. I lost 20rwhp with 2* of timing. Since I hardly spray, I am contemplating taking the 2* out. And if the digital is the answer, I hate to spend 3 bills when I've already spent over that on the 3 things I've already bought!!!

 

An aftermarket ignition box with timing retard function lets you pull timing when you run nitrous, yet let's you keep full timing for all other occasions. The ignition boxes also generate a hotter spark which helps to keep the nitrous from "blowing it out".

 

damn, I just bought an MSD6A not the "6AL"
I was wondering cause im rebuilding and im going to be putting on the timing chain/gears and thought it had something do to with it

 

You could have a second PCM chip burned that has custom timing curves and just swap the chips when you are at the track spraying.

 

I was just told that you didn't have to pull timing under a 150 shot...if there weren't any signs of detonation. How can you determine if it is detonating? I've already spent the money on all 3 items and I definately don't want to spend more on the digital box...so I may just pull the timing out. I mean, it's not like I have a 55 gallon drum of nitrous in my back seat that I continuously spray. I just hate the fact that I lost 20rwhp. Good or bad idea??

 

I've got new chips out that have a wire coming from them.. Ground the wire and you go into a nitrous mode.. or less timing and adjust AFR (if you give me a dyno sheet with the jets your using.)

 

so you dont need to pull timing for shots 150 and below??!

 

I have a dyno tune...will this chip work with that? Does it have a window switch in it? How much is the chip? How does it work??!!!!!!!!!!

 

That is what Nitrous Express told me. He said it was okay as long as there wasn't any detonation.
