need help with dry n2o tune !! hey guys,just got done instaling my nos 5177 kit and I need help with tunning for 42lb svo green top injectors and the dry shot.my goal is to run no jets but as for now I have the 100 shot jet in it.
I have HP-tunners but i'm lacking the skills at this point to tune.so if someone is willing to help me out I could send you my BIN file.
just for some other info,my car has many bolt-ons, G5X3 114 LSA,hooker long tubes,ported TB,ASP pulley,ect.my last wide band dyno showed 414 corrected rwhp and a/f was 12.9 @ WOT (tunning was done by wait4me performance)
I would like to get my juice up and running so I can get a few dyno's and some track time in before the end of summer...
ANY HELP WOULD BE GREATLY APPRECIATED..

I can set ya up. It's really quite simple. takes more time in the directing than in doing. I will honestly try to get it posted tonight, but no absolute gurantee. Might be as late as Sat, cause i am racing tommorrow after work, so if ya can hang in there we will do it for sure. I have all the known numbers that work and basically you will just be replacing old numbers with new numbers and it will work great for ya. I am running the 42's also.

Chris, do you have the injector spreadsheet calculator? If not, download it, simple, you plug in your injectors rated flow @ rated pressure, then maintain new fuel pressure as 58psi (standard value for LS1) hit tab or enter and it will calculate the new offset vs KPa. highlight the Kpa line and copy, paste it into your HPTuners file under engine, fuel, general (at the center of the general fuel screen is flow vs. KPA).
Next, I go to Inj. Min Pulse Width and lower by 50%, and ditto on the Inj Default PW. Now your injectors are set. It would be easier on the phone, or IM....

I have hp-tunners,but i'm in the very early stages of know how.I'm pretty sure that my timming has been advanced when I was tunned for the cam,so I need to pull some timming.then I want to get on a wide-band dyno to verify A/F.
