all motor tuning
My all motor b series should be done soon. Just got a couple questions. whats the best way to break it in? On the dyno? i heard i should run stock ecu stock injectors and put some miles on it but it has 12.1 comp pistons. JUst really lost with the breaking in. And also is neptune rtp a good program for all motor? Was gonna go with ectune until i read the problems everyone is having. Thanks

Your best bet is to figure out what tuning solution you are going to use, get an engine management solution & fuel system in place (injectors & fuel pump) and tune the car from the initial start up.

Re: all motor tuning
A few guidelines
Don't drive it on stock fuel and stock tune
Don't hold it at a single rpm for too long
Do give the rings time / miles / cycles to seat
With any new engine that's just been rebuilt
Do keep an eye out for your oil pressure as its paramount to the life of this new motor
When it comes to tuning check this out
http://horsepowercalculators.net/tun...ing-calculator
I wouldn't break it in on a dyno... dynos measure power by how much break force needs to applied AGAINST your motor and seeing how much the motor pushes back and what acceleration is achieved at that force difference (difference between your engine's applied torque and the applied braking)
That to me is against everything that breaking in is about (gently seating the piston rings against the bore).
That is unless you go to a dyno with a variable load (mustang dyno) and you can gently ramp up your break in process... and we're talking about an engine that was assembled in ideal temperatures (like how new mercedes engines are assembled in a chill room and all tolerances are taken in a controlled temperature to ensure a 0 tolerance build that can run a 0 weight oil at startup)....
If we're talking about the general backyard or your neighborhood mechanic rebuild, done to 'looser' tolerances ... you need a gentle break in

Re: all motor tuning
A Dyno is the PERFECT PLACE to break in a new engine. Tuning the engine from immediate startup on the dyno is excellent for getting your a/f ratio spot on and applying a LOAD on the engine (you need to apply a load and release to set the rings properly)
NOTE: I wouldn't recommend running the engine up to red line though until you get a few miles/ hours on the engine...
