i need a decent basemap, it doesn’t have to be perfect, but something I can mess around with while I put miles on the motor.

Re: Boosted LSV
Huntertuned also has some good videos on setting up a basemap imo, i am not a professional tuner in any regard - this is my map. I started on the itr stock everything file and inputted my sensors, injectors, and watched one of his videos and it fired up idling 13.0 over a year ago. Map was rich all over but not bad at all, higher rpm was pretty fat though. Rather pull fuel slowly than have a suprise lean spike on first pull.
I have driven the car well on this for ~15,000 and have successully blew my gsr tranny (now with long gear ls) this summer, still running fine and have taken it on multilple 300+ mile trips.
94 octane
B18B1 Block
P72 C1 head
Alpha clinic 750cc
PTE 5557 journal
Skunk2 pro cams, manifold, valves and springs
12psi, 14 cut
Temp comps messed to assist hot start please be aware - minimum comp load based, idle and light load tables changed. You may want to change these back to original values from a basemap. Cranking base pulse changed at 106f and up to 8.00ms, you could reduce this to 7.50ms, 4.00ms and 4.00ms if your hot starts are rich - I was chasing down a lean hot start/no start when first driving this in 2025 (18.0-19.0 before, now 15.5-16.0 back to normal 14.7 after 30 seconds)
~14.7 light load, ~13.0 medium load, ~12.0 full throttle
Rev limit 7211
Eld, knock and barometric disabled
Neetronics 3 bar MAP (gm map sensor)
Change deadtimes and injector size to yours. Set your tps. Change map sensor if needed. Adjust iac duty if hunting, this is set slightly below normal. Idle, part and full throttle tuned with 2 widebands plx and aem.
