A juicy girl got me, again
I made some changed and did the following one change at a time.
Pasted an untouched L31 VE Table, truck did not run very good this way.
So I put it back to the way it was when I changed the cyl volume to 383, when the program changes it for you. Truck ran good again.
Basically in small increments, doubled the BRAF to get the truck to start without throttle input. RPM was hanging a little.
Backed some idle spark advance off from 400 to 1200 rpm. Truck seems to like it so far.
There is still so much that needs messed with, but it is now running better than ever. Still trying to learn.
Follow this guide for tuning your idle. There's a lot of steps and it'll take a while, but it'll give you a great running engine. Once you finish that, go through and tune your VE table, MAF, and then spark. I recommend you invest in a wideband sensor with a serial output otherwise you won't be able to tune the open loop portions of your tables, AEM makes some great ones. Once that's done you'll probably need to redo the idle tune, or maybe not.
It'll take a while to learn the ins and outs of tuning. @L31MaxExpress is a pro at it, I can also help you along the way. Also the HPTuners forum is a great resource.
If you'd like I can send you my scanner config that has all the histograms and data points you need to do just about any changes.
