I don't know why it's such a big deal....Just lean out the idle and load maps...*shrug* Isn't that the entire point of a standalone? You won't be fine tuning it until it's broken in anyway...

 

thats unfortunate

 

Wow, sorry but my tuning skills are not as good as yours.

It just seems odd that you're saying the reason you don't do this with a sandalone is beacuse it will run rich...so why not just lean out the map?

Maybe instead of making sarcastic comments you can just explain to me why my thinking is wrong?

 

Base maps are normally rich.
You're trying to get a brand new rebuild running with an inherently rich map.
Most tuners go from rich to lean.
Motors with low compression (i.e. new rebuilds) usually run rich due to the lower compression.

All this points to a non-optimal break-in period.
This is why I don't recommend doing this.

Let me rephrase this...
If you can break the engine in on a stock ECU, I would rather do that.
If you got a pretty tuned stand-alone fuel map, that should be fine also.
If you have neither option, it's not recommend to try and break-in the engine, especially when you can't tune the stand-alone EMS efficiently yourself.
