LT1 2bar Help

[Dagridiron01]

Stock 94 z28 auto 42lbs injectors T67 turbo
Im having issues with her running once the 2bar map is installed.I scaled the VE tables down to half and turned on speed density and she still wont run it will idle for about 15 sec.Needing some help with this was wondering if someone had a 2 bar VE table they could screen shoot or post that would help alot.
Thanks

Start debugging by logging pressure vs pcm map reading. It needs to be linear as much as possible.
Hook up vacuum first than apply pressure to the sensor, while monitoring pcm data.
Than you will know if pcm reads correctly the sensor.

You have done this making the 1 bar system see 2 bar?

I didn`t but it is the correct way to see how the sensor is scaled within the pcm code. Some kind of custom calibration. If it doesn`t look good or linear enough some rescaling might be needed. There is also some baro corrections, updates that you need to get rid of too.

You will definitely lose some resolution. Wiring a second map sensor that is used for ve fueling only will be much better approach. Some custom patching will be needed.
