Help me finish my engine swap

Hey guys

Just finished all the mechanical work of a 2.5 to 3.0 engine swap. I'm now trying to get the ecu recoded properly. I have winkfp working and edited the zusb value, but am now trying to get the adaptations and such reset. I'm not sure which software is easiest to use for this.

I tried getting inpa set up, but it's completely frustrating me. Are there any easier to install options?

Are you saying you already updated the software from 2.5 to 3.0? If you did the car should be fully running.
Are you looking for throttle adaptations? Found this procedure on this website.
Here it is:

E46 Resetting Throttle Response

Over time your BMW e46 wil adapt to your driving style. Can you remember the days when your car would feel fast and spirited and jump when you touched the peddle? Have you lost that feeling? Well, it's not totally your fault. It's fun to go fast, but who doesn't like to get 27-28 Mpg? You can change back to a default setting if you wish.

Here's the steps for an e46. They are simple and easy to follow.

First, with the key removed, sit in the driver's seat and insert the key.
Turn the key to position "2". Position "2" is one position before the car engages and starts.
Wait 10 seconds and then turn the key back to position "0", which is the initial position.
Once again wait 10 seconds and then start the car up.
You should now have your throttle response reset and your driving pattern from this point on
will dictate how your throttle response adapts.

Over time your throttle response will once again become lacking and another reset will need
to be performed. It is recommended that this be performed every 3-6 months if you feel the
need to have your spirited car back.

An independent auto shop, using Autologic should be able to reflash the system for you , for around a hundred bucks.

My Ride: is not yet fast.
Inpa is surely the easiest way to reset adaptions. At least when it's running properly. What errors are you getting during your inpa install? I'll see what I can do to help

Resetting adaptations is a bit over rated. Note the word adapt is within adaptation. They will change without being forced, it just saves shops from having to drive the car to see if a repair worked properly.

If the engine does not run well now, resetting the adaptations rarely will solve other problems.

The dme has to be flashed again, and set up for the 3.0 engine ,instead of the 2.5. Adaptations has nothing to do with this. Both engines use the same DME, but the 2.3 engine uses a different one. also the 540 V8 uses a different one. You are either going to have an indy do the flash for you, or the dealership , which would be costly.
You can install the engine and hook every thing up. The engine and the car will run, but to get all the benefits of the larger displacement from your new 3.0 engine,it has to have the flash performed.

If you just updated the DME using WinKFP, then you need to clear error codes and reset adaptations before attempting to start the engine. I use BMW Scanner 1.4 for that.
From the top menu: Units, DME, Reprogramming, EWS-DME adaptation
