ECU mod and cold start removal

I'm researching ECU mods as my first car mod.

I'm surprised there's not a sticky summary thread on this forum. Realy PITA the search thousands of lines looking for the few informative comments in a thread instead of people ragging.

Anyway, what's the point of eliminating cold start? I actually like how the car is extra loud for a bit when you start it up. Makes it sounds like more of a beast.

I like how BPM gives you lots of fine tunability in the mod like redline, top speed limiter, cold start RPM limit etc. But it looks like their gains barely eak out 10hp and very little torque.

ESS looks decent too with the same customizability.

I'm preferring AA right now.
Active Autowerke gets 15hp and 11 torque at the wheels. Same as ESS I guess.
But, Their tool is compatible with Mac (just means I don't have to install WinX on my macbook now).
And Their software is on sale from $1000 to $800 right now and comes with the Simon 2 ODB usb cable.
Also they have the Data Logger software which is pretty sweet.

I am thinking of starting with ECU mod, then adding intake, under pulley, then exhaust. Then sometime down the road adding a super charger. I like AA because they go up to 700 hp. But might not want to go that crazy and stick with their L2, which is cheaper than ESS for he same HP.

I've got some more forum searching to do to read others experiences, but I'd appreciate some advice on my proposed plan.

Point of eliminating cold start routine is to reduce the amount of noise (which can be overbearing with some modified exhaust systems).

We have a virtual machine designed for Mac users. Gains are 10-35 hp, depends on what software you currently have, your mods, and octane level. All NA tunes are likely to yield similar gains. We also over servotronic steering changes and a couple other cool features.

See http://www.bpmsport.com/BPMTune.pdf and let us know if you have any questions

Fortunately, these days there are A LOT of great options for E9X M3 DME Calibration and Tuning. I think in the end, you probably can't go wrong with any.

I personally went with the Evolve Automotive Stage 1 Tune as my very first modification and have been solely pleased with the product.

My Evolve Stage 1 Tune review is here: http://www.m3post.com/forums/showthread.php?t=659146
My Evolve DCT Tune review is here: http://www.m3post.com/forums/showthread.php?t=874366

Like what Mike Benvo said, the Cold Start Delete is really nice because it does reduce the volume upon cold start. Best of luck with your search!

I was a little concerned about that mod. I'm not sure I want to mess with the steering. It's just another variable I have to worry about if something isn't done right for the car. I'd rather focus on strictly power related items until I get more data that would support messing with other parts.

Doesn't really mess with anything, it's all electronics. It's an option, most people that have it, love it. I can't drive an M3 with the lighter steering anymore. If anything, there is less assist and theoretically that may make the components last longer. It comes with the tune too, but everyone has a different spec/mod list to their liking

Actually I would like that... steering is too light for my liking.

I was on the fence about the servotronic changes as well but I'm very happy with them. Every time I drive an M3 without it I hate the steering now. Go for it, you won't regret it
