Just got a new (rebuilt at Pineapple Racing) engine.

ECU is Power FC.

Turbos is T04S.

I had planned to take the car to Ground Zero last week to get an initial tune so I could drive the car a few hundred miles to break in the new engine (yes, I know the procedure should be more like 2000 miles, but this car is not normally driven on the street - just need some break in miles)

GZ's dyno broke last week, so there went that plan. The new O2 sensor for the dyno will be there in a couple of days, but my vacation days will be over at that time.

Here's what I would like to know: Is it really necessary to get an initial tune for this?

Or would it be sufficient to reset the Power FC to default values and let it 'learn' the car, just so I can break in the new engine. Then I could go for the dyno tune.

The car seems to be running too rich, and I don't want to drive it that way.

Thoughts? Comments?

Thanks.

 

When you break in an engine, you do not get into or try not to get into boost over a couple psi. You are also to keep the revs down lower.
You slowly build up revs and boost.

Set your rev limiter to 4000 and drive easy.

Any base or stock map will do fine for this. If rich, why haven't you leaned it out?

 

Thanks, I'm familiar with the break in routine.

I haven't leaned it out because I haven't yet learned how to tune the Power FC.

I would prefer to have an expert tune it, then I can learn to make small adjustments over time.

What I need to know is if just letting the Power FC 'learn' the engine is adequate for a few hundred break in miles.

 

The PFC only learns idle. Read the manual and get to it.
