kinda thought I had too much in there but it doesnt seem like it driving it and the plugs actually look decent but thats what I thought just dont know why its taking so much timing to get it to run but the only thing im not certain of is if the timing mark on the balancer is right... normally when I build a motors I degree and mark the balancer for true tdc but I didnt build this motor it is a crate motor somone else put in

I am also having an issue my adx will not show me history tables and im ignorant as to how to add that feature

Honestly, start with a bone stock bin, don't try and guess what you think the engine will need, the engine will tell you when you try to start it.
You'd be amazed at how well a stock bin will get an engine up and running.
The only things I generally do, is disable closed loop right off the bat, and set any scalers that may be drastically different from the original application to the new application, but I generally try to find something close to start with anyway. In your case, I would start with an $8D bin for a 5.7, with the same trans, and only disable closed loop.
When trying to start the engine, you will see if it's getting too much or not enough fuel, spark advance being enough or not, etc.
I find that when someone tries to "guess what an engine wants", they usually don't guess correctly, and then find that they have issues later trying to tune something out, forgetting that something they changed for the start tune.
The man who says something is impossible, is usually interrupted by the man doing it.
thats where this started at and thats the point I have gotten too ....I was told this would never work I made it work maybe not right but I would like to get it a close to perfect as i can...I just went back and looked at the sa tables and they look crazy out there and dont know why at all....I added timing but like 12 degrees across the board...but thank you people for the help I never even caught the simple stuff...I downloaded the super 8d stuff ,is this something I should consider or not ?

Did you set timing with the bypass line disconnected? It's like pulling the timing spout on a Ford. The engine should be able to run with the bypass disconnected as well. It won't run well, but it will run. I'd start with that, to make sure the distributor is in the right place and to be sure it's all wired correctly.
Even if you take out the 20 bias the spark table is crazy? But max spark in bin set to 34? Base timing at 1? Log shows your in ALDL mode? Hitting 96 degrees advance? Unless your doing something with your XDF and ADX this is firing 2 cylinders off? How do BLMs look good?

I dont think any of it looks good Im just happy it is mobile but would like to get it right .I cant figure the whole history parts out so I am blind at best but it seems to actually run decent.. I did have to jack fueling up at start a bunch which I thought was odd and had to pour the timing to it to get the motor to wake up now I am still not really well versed on this gm stuff so please do tell if anyone can help...again thanks

This might be a good time to test JeepsandGuns new XDF and ADX...
