it says no tuning required but....... I want to put in a 224/224 114 cam and they say no tuning is necessary.
What should I plan to change, PCM wise, to get the most out of it.
No other mods on the motor.
Thanks

You can customize almost every aspect of your tune. Primarily, you will want to retune your idle and VE table and possibly adjust your MAF table as well as WOT. If you search the topics i just listed, you will find more than enough info to get you thru it.

Even if you are completely stock, you will find benefits in tuning, especially if you do it yourself (...tweak it to the n'th degree...);
there's a steep learning curve, but it's Very rewarding, and knowledge is power (literally).
BTW: your Bimmer (2500 lb) has a very favourable power:weight ratio.

I agree, Ive spent about 6 weeks with efilive and now am pretty happy with the tune, Im stock with most bolt ons and the car goes like its had a new engine. Loads more power everywhere. Thanks to all the guys on the efilive forum and on here too, plus some book reading, lots of logging and plain fun.
Go for it, if you can spare a few hours now and again you will get there and think of all the diagnosis and troubleshooting you can do with the right tools. It will save you loads of cash in the long run.

All modded cars can benefit from a tune. The main thing for most cam swaps is to reduce the first 3 columns of the VE table for cold and hot starts, usually, 65, 75, 85% should help out a lot.

Thanks Bill, that is the information I was looking for. I also got some info that indicated I might need to add some advance for idle and richen up the upper rpm ranges as well. Do you agree? Not looking for specifics just generally.

That cam is a great cam to tune, not too many issues. Bump up the whole Idle table by 25-50 rpms. You want to add a little (5-10%) to the Idle air table in the colder areas.
There are many things to tweak but start with those that I have listed.

Not to mention the fact that it's making great power quite a bit past the stock 6200 rpm rev limiter.
But, a cam shouldn't be your first mod. It's kinda a waste of money if it was. Without supporting mods (intake, exhaust, headers, tuning) I doubt it would be worth the time to put the cam in.
