ECU Mapping
 
What is a good software package for DIY fuel,ign, and vanos tuning.
I am looking at getting an E46 to replace my E30 and want to do my own mapping as I have the ability to dyno tune myself.

Never seen or heard of such a thing (custom software) for the E46.....even the big guns like Dinan don`t have that in their arsenal. The "normal" stuff like the Conforti Shark, Dinan chip, etc., has not proven to be worth the price of admission.

i'd call around some tuning shops and see what they use.

engineer_smith 10-23-2012 05:55 PM

what about people adding performance parts how are they remapping their ECU's?
Are they just getting maps from aftermarket suppliers or are they doing custom mapping?
Im basically looking for something like EFI Live for a BMW

You really need to start reading this Forum more often....these cars are not like Hondas, Camaros, Mustangs, etc. (i.e., all the bolt-on stuff that enhances those engines doesn`t work on BMWs). The only "performance parts" worth investing in is a supercharger, which is typically a $7500 (or more) investment, and comes with it`s own supporting electronics. Other than FI, there`s not much that will add any significant power.

i have to disagree with u Bob on this one, where i am, tuning shops do ECU remaps for around 600$ and give u an additional 15hp (dyno test seen)
if u have installed aftermarket parts expect the gain to increase even more
ECU remaps vary based on the company, i can't remember which company had that software, but i'm sure to have that remap once i get CAI and headers.
one thing though, will an ECU remap overwrite the Shark Injector software? :eeps:

Sorry, but I`ll believe that one when I see it. And, Bucko, your car already HAS a CAI....the most effective one available. And yes, the overwrite would negate the Shark....

Seriously, man....you need to refocus your energy....you`re talking about spending a substantial amount of dough on all this crap, and FOR WHAT ???? **Maybe** your car will be a TENTH of a second faster in the quarter-mile ??? I fail to see the logic there.

i'll see if my friend still has the results printed from the dyno test

i do believe there is a gain of 2-3 hp, for a custom built CAI for around 80-100$ (the work in progress one i'm planning right now) i don't think it would hurt my wallet much :dunno:

1,000$ for custom CAI, + Headers (bimmerbrakes) + Remap, and get gain of around 35 hp, i don't think it is that substantial amount of dough :dunno:
and it's not just to gain that tenth of a second in quarter-mile (i believe the difference would be more with those upgrades) u'll feel ur car very more responsive and torquy when hitting those twisties :D

There is no need for the CAI. It will not give you more gains since the BMWs already have a true CAI. The headers, maybe around 15 hp. You should get cheap ones of ebay and ceramic coat them. BMWs are already well tuned from the factory. You may want to reset adaptations after that, but that is it.

You`re overlooking one important fact....*mods are not cumulative*....so, IF that Magic CAI promises a 5 HP gain, headers, 15 HP, and a remap, 10 HP, you THINK you`re getting a 30 HP improvement, right ?

Unfortunately *not*....the values for each mod don`t "stack up".... in The Real World, you`d be lucky to get a true 20 HP increase.

Question is which E46 will you be getting?
Anything MS45 will be a challenge unless you have enough money to throw into Dimsport software/hardware or equal dealer style software going for $5,000 USD+

MS43 you can do with Tunerpro and extracting the DME BIN files. you will need the hardware to flash/extract. make changes in Tuner pro, I think there are a few with checksums already.

Or you can go with a piggy back.

I'll just leave this dyno chart here:

http://www.e90post.com/forums/attach...1&d=1353969338



To summarize, that car has an intake, pulleys, cams, exhaust, headers, a downstream catalytic converter, and a 3.64 LSD and it ONLY made ~15 additional WHP. I don't see software listed on the dyno, but even if they did re-tune it, they MIGHT gain another 6 WHP (on a good day, that is). Average software flash on an otherwise stock car was between 3 and 5 WHP. Hell... when I dynoed my first E46, there was a 4 WHP difference between pull #1 and pull #3, so I'm not entirely sold on the software thing.

When I had my first E46, I put headers on it (thank you smolck for installing those buggers) because I had money burning a hole through my pocket and I wanted to see what the hype was about. There was a noticeable gain in overall power and torque, but it was still wasn't as fast as... say... a 350Z. Don't get me wrong, it was fast enough to have fun and get in a fair share of trouble with, but it's not setting any quarter-mile records. With that said, I'd say headers are a better bang-for-the-buck mod for power than software, but get ready for a constant SES light. With all that said, I actually considered getting an Active Autowerke tune just to get rid of the SES light caused by my headers. If I happened to pick up any horsepower from it, then cool... that's a bonus.

What we're trying to say is this: You mod your car however you want. We're just trying to save you the money of buying something promising a 15 HP gain, only for you to come back and say, "Well crap. That kind of sucks."

Fast Bob 03-21-2016 10:02 AM

Agreed ^^^^^^^^^^^^^ Spending thousands of dollars on all this stuff, then to barely feel any seat-of-the-pants difference pretty much defies logic....it`s just a piss-poor return on a sizeable investment....

The reality of the situation is that E46s just don`t make good hot rods....

Once again:
"Learn to love what ya got, or sell it and buy a faster car"....
