can anyone send me the calibrations needed for injector voltage compensation and fuel trim for my setup. or even better a basemap would be nice

car type civic 1995 4 door
b16a
garrett nissan rb25 turbo open at 1 bar
OMNI 3 bar B series map sensor
AEM fuel rail and regilator
1000cc precision injectors
Skunk2 66mm Alpha Throttle Body
BLOX POWER INTAKE MANIFOLD up to 72mm
Golden Eagle Cam Gear Gears
Wiseco Forged Pistons Eagle Rods 10.75:1 81mm
b18c type R camshafts and lifters
5 bar fuel pump

if you get in contact with precision they will email you the latency value&voltage setting for them i do it all the time

Change the turbo please. Such a nice setup at least put in a Evo turbo or a gt30r. If you have holset hx35 in reach use that.

And please do not boost on this map. You will blow something up for sure. Even with race fuel its crazy. I will give you a better basemap to start with just don't use this.

Its just the b16agreddyturbo base maps that come with the smanager software with the 3 bar map sensor settings and launch control, shift light, rev limiter, and vtec opening times changed. Could it be that bad?

The ignition timing is really advanced brother :)

I got a reply from precision about the injectors with these timings

The following are the latency @ voltage values for our 1000cc injectors:
 
Open Time Latency (ms) @ Voltage  -->  1.63ms @ 8.7v   1.00ms @ 10.4v    .80ms @ 12.2v    .70ms @ 13.9v   .60ms @ 15.6v   .56ms @ 17.4v    .56ms @ 19.1v    .53ms @ 20.9v
 
If you need to convert the latency values to microseconds, move the decimal 3 places to the right.  For example the first value would be 1630 microseconds @ 8.7 Volts.

But i read somewhere in one of the posts that i should set the current cc of the injectors at 880cc even tho they are 1000cc cos they only give you 880cc real time. Should i do this or leave it at 1000cc

all my tunes i always put the entire cc of the injectors from 310 to 1600
