Hi, i have a 383 in a 87 iroc with a stealth ram. it has 30 pound injectors. I have tunercat and am trying to learn to tune it myself but I cant get it close enough to start trying little things to learn what they do, I was wondering if anyone could help me out and tell me where to get a good base bin that will work ok, and what i should set my injector flow rate to compensate for the big injectors. I not begging for a prom, just wanting some advise on how to get it close. the car has alot of bugs and i need to be able to drive it and work the bugs out so I can take it to the dyno and get it tuned right without having any other problems. Thanks

Depending on your build look at arap and aujm sa, you will need to do some data logging to tune in your lv8.

 

I am working on getting a laptop and the cable so I can datalog, where can I get the arap and aujm sa bin's at?

Ok thanks, I'm new to this and really appreciate any help i get. Hopefully over time i get learn enough to be able to help others that are new. I'm going to try the arap bin and set the injector constant to 30lb, I only get a chance to work on the car on the weekends so Ill post how it turn out this weekend.

 

you will need to work on your Injector PW correction vs Battery Voltage. but like I said If you are not dataloging your wasting your time. You might want to read the stickies . the arap (sa) is more aggressive aluminum headed l98. Both these .bins will need the vats disabled and fan switch setting changed.

 

I was looking through my old test bins i played around with and by the notes I made the best it ran was with 27lb injector constant, but im going off of my wideband 02 gauge and i know thats not the same as datalogging. I always set my fans to tur on low, stock radiator and it runs warm, thats one of the bugs i need to fix need better radiator, and i know how to disable the vats, I don't really know what to do with the injector pw correction. But ill keep reading the stickies and try to understand it

 

although this is based on $32B its a good article. I believe there is a patch for $32B wb but not positive.

I really thank you for your help, Ive been on message boards before and no one wanted to give me any help. Ill let you know what I come up with and how it turns out.

 

There are some things you can do to speed things up with a ostrich or apu1 or switch to sd and go with dynamicefi ebl p4.

 

Ok you lost me on that one, like I said I'm new to this and I try to read up on it when I can but don't get alot of time, still don't know about alot of it.
