Eurocharged Performance Tuning Interest at ZHP Mafia SigFest 2012

[az3579]

Seth said Eurocharged works with AA, and my AA tune upped my MPG by 2-3, so maybe that's an indication. Then I added pulleys and it went down 2.

You have to retune after you make a mod like pullies. Sometimes a mod makes mpg go down, regardless of a retune.

Really? That's good advice, I didn't realize that. EDIT: I don't want to hijack this thread, but just to keep everyone updated, I called Autotalent who did my s/w, and they will call AA on Monday. He didn't think it would be necessary. Hopefully we'll get a definitive answer for those of you considering this. The primary point of my original post was though, that mpg did go up with a tune. Thanks again for the info BP.

yeah most good tunes will up your MPG's a touch on the HWY - just the nature of what making more power does for cruising. You WILL see a drop in MPG's on our tunes in the city though - because you can't help buy floor the thing from light to light.

Seth, mine went up overall, even with mostly city driving and more of a lead foot.

Nice. I do about 90% hwy so I just open it up there and not when driving around town - cops are dicks around here.

I definitely try to be a polite lead foot. Heavy on the gas, not too heavy on the speed limit per se (except for sometimes.)

[Eurocharged]

Lol same but it's not easy

I'm going to ask a few questions out of pure ignorance:

How do you achieve your gains - what's changed in the mapping? If this is on your site, I apologize for missing it.
I'm under the impression (perhaps wrongly) that BMWs have adaptive ECUs - how does your tune "stick," or does the ECU get rid of it over time?
Are these "canned" tunes, or individual to each car? If individual, do you drive the car while tuning?
Have you tuned a ZHP? Couldn't find one under "testimonials" on your site. If so, what did you find as far as areas to make power other than, say, leaning it out a bit?
How does your tune affect my ECU's "4,000 rpm dip" fix from BMW?

Some can be answered in the main Eurocharged thread but I'll try to get it all answered here. Let me get to muncomputer

Most of these can be answered in this thread:

Some of the MANY areas (but not all) that we are able to modify to make the ZHP faster and more powerful are:
-Ignition advancing
-Air mass flow
-Fuel mapping
-RPM limiter
-IVVT set points
-Valve spread on inlet cam
-Thermostat control
-Fan speed control
And most importantly for the Steptronic Transmission guys - Throttle sensitivity

I'm under the impression (perhaps wrongly) that BMWs have adaptive ECUs - how does your tune "stick," or does the ECU get rid of it over time?

They do, the car will still adapt but using the the new DME programming so it is always the case that the car will pull harder after about a few weeks than it did the day you got the tune.

Are these "canned" tunes, or individual to each car? If individual, do you drive the car while tuning?

no we actually create the maps for each car. It is common to save time to use other customers files we've already done and had success with if it works with your software version and current mod set up but only in those cases as we'd be tuning the car with the same perimeters anyway, it's just eliminating time out of the process.

Have you tuned a ZHP? Couldn't find one under "testimonials" on your site. If so, what did you find as far as areas to make power other than, say, leaning it out a bit?

We have done a small number of them tunes right now (including myself). I am still waiting on some dyno time with my boss to be able to go in and get some numbers recorded. The one car we did do (jayjay_dee) looked like he might have had some preexisting mechanical issues as his baseline and tune numbers were low for the ZHP.

How does your tune affect my ECU's "4,000 rpm dip" fix from BMW?

A: At this time our base ZHP software eliminates SOME of the dip but not all of it. The more and more time we have working on ZHP's the more likely we will be able to eliminate it by finding out the source of the issue that causes. If/when that is totally fixed it will end up being our NEW ZHP base tune that we will build off of for each customers tune (unless specified that you don't want it altered). If you have the dip and were tuned before this you will be entitled to the newest software.
