base map for ITB 440cc on TPS

Hi All

Getting a bit mixed up with the maps i have.

I am looking for a good base calibration for

B18
ITB
440cc Bosch injectors (12.5ohm)
TPS
(with MAP if needed)
OBD1 ECU
s300
50psi fuel

I had it running. and good 14.7 afr but it was messing about 50% load on. then realized the stock calibration was secondary map on MAP. Changed TPS calibration to 100% rather than 40% with no MAP. for some reason i cannot even get the car to start now. The customer did put the IAT pins in the wrong way so not sure,

Very weak signal at injectors and full spark

Loaded on last known good calibration and still no start. notcied for some reason TPS had jumped to 20% at closed. it was on 0% before so i reset that in the calibration.

does anyone know if the stock "ITB.SKL" calibration will work with my set up if i run a MAP.

Thanks all

It was running without map using Alfa n. However it won't run at all now for some reason
