The Express van tune files seem to be most accessible. And work great.
Tried years ago to tune my truck after the intake swap with 25lb injectors and a touch bigger cam than listed above. I agree they are maxed out above 5k. Switched to flex fuel injectors quickly. I...

Leave it factory location. Or put it closer to the filter. Adjust your table to start removing timing at 115F get aggressive taking timing out after 130.
Good choice ev6 connector swap required. Make sure the data is correct the first time around.
Nothing further from me. Do as you will this is a free country.
This is a direct file from lextech. These spreadsheets he has specifically asked everyone not to share. Rightfully so in my opinion, Your not helping by posting this. Your showing how to disrespect...
Repository
E mail Lextech for easy to use pinout spreadsheet. $20usd or go to lt1swap.com and cross reference the pinouts with a black box. and start swapping wires over to the new 80 pin connectors.
melonized is correct. Your distributor gear smashed into cam gear. Shim your distributor up with atleast one more distributor gasket. Do not tighten it so tight you can't turn the distributor by hand...
From my experience. The camshaft sensor will cause an intermittent loss of spark/spike in spark. Usually while running cruise speeds or under heavy acceleration.
Confirm good ground continuity,...
Pull a plug check fire, Confirm fuel pressure check that no fat finger mistakes are within the tune file. Basic diagnostic skill for the win here.

Get your fuel pressure 58 psi and begin tuning.
Add to Startup airflow initial table.
The tune file i sent you is speed density open loop setup. the VE table will be your main fueling adjustment. From what im seeing here it needs a bit more initial advance closer to 22 than 17. Also...
There is no manifold volume adjustment in the p01-p59 pcm. In the fuel tab under transients you will find multiple tables multipliers and adders
You are missing intelligence. ghost cams are bad tunes made worse. Just don't
I use a corvette fuel filter/ regulator on that setup it is supposed to be 58psi it usually runs at 60-62psi not my favorite method but a rather cheap effective one. There is no need for payment...
agreed rarely does a cap last me more than 9 months. Or 15,000 miles possibly because the increased dwell?
We should all be aware by now these style caps are absolutely terrible. Been running them for years I always prefer to use ac delco caps. I've had my plug wires resting on my fuel rail for 4+ years...
Yes put the harness back as the original van harness. I'm convinced you are creating your own issues at this point. I would like to see some pictures of this distributor cap creation. What is this...
Sounds like typicak crossfire within distributor cap or firing order issues. Jump the starter without fuel or the coil firing. If it cranks smoothly without ignition its a firing order issue....
Transient fueling is likely the tip in issue. Fixing your transient issues will slightly alter your fueling so your VE table must be dialed back in afterwards. I might get some flak on this but i...
