TIMING RETARD DEVICE FOR NITROUS?
I'm using a 100 shot of nitrous on a stock motor except for the tuning is customized by Bryan at pcmforless. He said that he had advanced the timing by 4 degrees in the programming and recommends pulling that back out when using nitrous. I know they have devices from ramchargers and others but surely there is a way to do the same for considerably less money! Some I've heard are using a simple resister wired into a relay that works great. What value of resister are they using and what wire are they tapped into?

I've been speaking with ICU , who is basically the Nitrous contact here on the forum, and he has somthing in the works now. I believe there was some type of hold up with the shop he had contracted with. :smash:
I ran somthing like this on my C4, and it works great. It will allow you to have Brian tune your Pcm for max. performance, and still allow you to run your N2O.

Here is tip that I use when programming and setting up for nitrous!
You can pull timing out with Ls1 edit !
There is a table that removes timing in the degrees you select based upon
incoming air temp. Here is the trick-- We have a dual range TPS on the throttle body One side the voltage drops to the pcm as we increase the
throttle. At wot this voltage is tapped into the iat input via a switch. The computer will think the air is the voltage drop temp equal to wot tps volt.
Go to that temp in Ls1 edit and select any timing number you want pulled out. This will only happen when you turn the switch on and are at wot!
Have your programmer e-mail I will help him to do it.

Re: TIMING RETARD DEVICE FOR NITROUS? (Richin Chicago)
These modules are all very well and fine but I guess what I was really looking for in this thread is a cheaper alternative to these $289 devices. The resister trick sounds more like what I'm looking for if I can find out more with regards to resister values per given timing retard and exactly where it needs to be wired into. There's no sense in spending almost 300 bucks for something you can do with a 5 cent resister (which I have a million of in a variety of values already!) The programming trick that Gooseman mentioned sounds very interesting as well! The only prob is I don't have an LS-1 Edit and I'd have to send my pcm back to Bryan for another reprogram. :cheers:
