CA18Det Help with my rom tune, please and thank you!

[DEEPfrom1]

Hey everyone, I am running a CA18det, Gt28R turbo, Front mount, DSM 450's(blue top), 3" turbo back and a z32 maf. I got the car this way and have been fixing the odds and ends, and de-ghetto-ing it. The car has a SPL Brain "ECU" central 20 racing chip. I know not a thing about the file thats on the chip. The SAFC is not much of a help.
Does anyone have a decent basemap they could email me? I have tuner pro on my laptop and can burn the new chip inplace of the current. I will pay for a good basemad, JWT wants 4 weeks and $500, Enthlapy is thinking about making me a chip, doesnt spend much time with the CA's. I need some help here!

Thanks everyone for readin!
