Has anyone had there pcm tuned by a tuner for nitrous, not a handheld . I'm going to install a 150hp nx wet kit on a stock ls1 with a few addons and thinking of getting a tune if needed by a tuner. any info would be greatly appreciated. Thank You

 

looks like no one gets custom tuning for nitrous ,that seems odd with all these tuners out there doing tuning for different applications.

 

bolt on car? just going to fix ur af and maybe pull 1 or 2 degrees out

 

i hit mine all day with no timing retarded at all and the a/f was adjusted and that it.

 

have your tuner tie into the other wire on your pcm and do a nitrous tune...when you go to spray, just ground that wire and you'll be set

I have a buddy of mine tune it. The biggest thing is retard your timming and and getting your air fuel correct get on a dyno. Or buy a wideband. Going to a 150 shot or higher you need to do one of these to be safe. Go with colder plugs.

 

A timing retard would be better than letting the knock sensors pull the timing

 

Can anyone explain this in great detail? Such as which pin, how this works, who has done it, etc? I was thinking about going the Timing Tuner or MSD Timing Twister, but this sound like the best bet. Thanks
