break in tune
hey guys i had a motor pop and am currently in middle of rebuild going with map stage 2 fully built short block and i had my head redone with brian crower valves, retainers, and springs. and stage 2 cams i also picked up a fp red. i got id 1000cc injectors
so my question is as long as i keep my foot under 25% throttle and stay the **** outta boost would the stock map work to help break this bad boy in i know nothing at all about tuning im just a back yard wrench puller. i know id have to do some dialing in for my injectors but i think i can handle that

As Per Cosworth break in procedures:
Engine Break-in
It is critical that the engine is not started with an excessively rich fuel mixture. An excessively rich mixture will wash away
the oil in the cylinders and the rings can potentially never break-in causing excessive oil consumption, crankcase blow-by
and lower power output. This damage is permanent. If the engine will be broken in by driving the car, we recommend you
keep the engine speed below 4000 rpm. Drive the vehicle at various loads, speeds, and throttle positions while keeping
engine speeds below 4000 rpm for approximately 1000 miles (1660 km). The longer the engine is broken in, the better. If
breaking your engine in on an engine dynamometer, we recommend the procedure detailed below. This guideline can be
used on a chassis dynamometer also, but load readings will differ. Be sure to keep water temperatures below 203°F
(95°C) and oil temperatures below 230°F (110°C).
Dyno Break in:
• Run at 2000rpm @ 50-60 lbf-ft. (6.9-8.3 kgf-m) load for 20 minutes
• Run at 3500rpm @ 90-100 lbf-ft. (12.5-13.8 kgf-m) load for 20 minutes
• Run at 4250rpm @ 100-110 lbf-ft. (13.8-15.2 kgf-m) load for 10 minutes
• Run at 4250rpm @ 125-135 lbf-ft. (17.3-18.7 kgf-m) load for 5 minutes
• Run at 5500rpm @ 125-135 lbf-ft. (17.3-18.7 kgf-m) load for 5 minutes
• Run at 5700 rpm @ WOT for 2 minutes (not to exceed 300 lbf-ft./41.5 kgf-m)
During the final break-in stage, the boost should be limited so as not to exceed 300 lbf-ft. (41.5 kgf-m) of torque. Some
initial ECU calibration may be required to complete break-in. The engine should be calibrated to achieve an air fuel ratio
rich enough for the type of fuel you are using. Consult with a professional tuner for air fuel ratio requirements.
Boost helps seat your rings.
