I was not aware. But still do not know what the PROcede's baud rate is.

There is nothing about it in the Haltech Interceptor manual, or on their forums. Have you tried something like this: http://www.microsoft.com/technet/sys...s/portmon.mspx or this http://www.serial-port-monitor.com/ ?
You should be able to see all of the COM port settings from the Reader software, including baud rate. So that could be run to see the settings used by the Reader for the hardware COM port.

Version 2.0.2
Read Me
Two Versions

I. Please note that there are two version of this map. v2.0.2 6AT is for Steptronic Auto. v2.0.2 b6MT is for the manual transmission. It is important to run the appropriate map. Running the wrong map will induce drivability issues and potentially trigger diagnostic trouble codes.

Uploading The Map
I. Disconnect The Battery
II. Ignition On, Engine Off

I. Before you upload the map, disconnect the negative pole Of the battery for 45 minutes. Remove the tool box panel on the right side of your trunk just behind the tail light assembly. Don't close your trunk until you have reconnected the battery. Remember to reconnect the battery before proceeding to the next step.

II. Upload this map like any other map using the PROcede user software. Ignition on, engine not running.

User Maps
No Adjustments To User Settings For 50 Miles

Do not make any adjustments to the User Adjustable Torque map before uploading. The default settings are calibrated to provide smooth and consistent power delivery on a stock 335i/xi. It is recommended that you run these default settings for at least 50 miles before modifying any setting.

Adjusting User Torque Table
I. Stock Settings
II. User Defined Torque Settings

I. The default settings are 90% across the board (at all engine speeds). This is the suggested setting if you want a conservative tune. With these settings, boost pressure will be approximately 10-11psi until 4500RPM and gradually ramping up to a peak of 12-13psi by 5500RPM. These settings will provide approximately 340-350whp (or 380 to 390bhp) on an otherwise stock car, running pump gas. If this is good enough for you, you can skip to section about Fuel Requirements.

II. For even greater performance, the User Torque table can be adjusted upwards. To do this safely, you will need to monitor maximum boost pressure. Preferably with someone else driving your car and your laptop on your lap with the communication cable running through your window. Boost pressure is displayed (in PSI) in the User Software. The maximum allowable boost, at full throttle, should be no greater than 14-14.5psi at 5500RPM. If you chose to run this maximum allowable boost pressure, you will need to raise the values in the User Torque table. Do this by adding just 2% across the board (at all engine speeds). After this adjustment, measure boost by conducting 3rd gear, full throttle pulls from 3000 to 7000RPM. If the desired boost pressure is still not achieved, you can add another 2%. And test again. To make fine adjustments to peak boost pressure, 1% increments (in either direction) can be made. To achieve the maximum allowable 14.5-15psi at 5500RPM, you may ultimately end up with 94-96% across the board. This is normal. Do NOT arbitrarily set all values to 100%. This is bad. It can cause engine damage.

More About Boost Pressures
I. Monitoring Boost Via PROcede Software
II. Using A Boost Gauge

I. If you don’t have a boost gauge, you will need to temporarily monitor boost using the PROcede software (and your laptop). It is important to realize that this boost reading comes from a boost pressure sensor which is located in the upper intercooler pipe, NOT in the intake manifold. As such, the boost readings will be subject to short term spikes upon sudden throttle openings and closures. Ignore these pressure spikes. It does not represent the pressure in the intake manifold. Boost will also fluctuate depending on ambient temperature. On colder nights, boost pressure may be slightly lower. On warmer days, slightly higher. But regardless of conditions, the maximum safe boost pressure of 14.5-15psi at 5500RPM still applies.

II. If you do have a boost gauge installed, make sure that the boost signal is coming from the signal line used by the bypass valves. Also, make sure the gauge is properly calibrated. It must read 0psi with the ignition on the “ON” position (but engine not running). Many inexpensive mechanical boost gauges (Autometer... cough cough) are often hopelessly inaccurate and can provide false data.

Fuel Requirements
I. Minimum 91 (R+M)/2 Octane
II. Unleaded Race Gas

I. As always, you must run premium grade fuel with this map. In CA (and some other states) the best gas available is 91 octane. If this applies to you, you can run this gas. Just make sure you use a reputable gas station. Brands we found to work the best (in California) are Shell and 76. In most other US states, 93-94 octane is available. If this is the case where you live, you must use it. Use a reputable brand as well (no Costco, Rotten Robbie, etc.) Running substandard fuel can result in drivability issues and even engine damage. For those who live in other countries, please note that US octane ratings are different than your octane ratings. Since they are not measured on the same scale, you must take care in choosing the appropriate fuel. Due to the difference in rating technique, the nominal octane rating will be much higher than the 91-94 octane we get here in the US.

II. It is perfectly acceptable to run high octane race fuels (Unleaded only!) with your PROcede. Mixing pump and race gas is also fine. Doing so will result in high power output and improved engine response. When running a higher octane race gas mixture, is also possible to raise boost pressures beyond the 14.5-15psi maximum pressure specified above. Additional instructions will be provided for doing just that in due time. For now, however, do not exceed the suggested boost limit.

Drag Racing/Road Racing
I. Fuel
II. ECU Adaptation

I. Although v2.0.2 is suitable for pump gas, additional performance can be had by running high octane race fuel. Even without any changes to the User Torque table. For optimal drag racing results, run with 1/4 tank of unleaded race fuel. To do this, run your tank down to the point where you dash computer says you have 0 miles left (don't worry, you actually have 10-20 miles left). Then add 5 gallons of unleaded race gas (VP109 works great!).

II. Before running the car at the strip, do some 3rd gear pulls on the highway. This will allow the ECU to adapt for the higher octane. This will yield noticeable power gains. For road racing, it is advisable to run at least a 50/50 mixture of race gas and pump gas. This is because of the sustained thermal loading your car will be subject to during hot-lapping conditions. The race gas mixture will prevent ignition timing retard caused by elevated intake charge temps. This will keep the car running more consistently and cooler.

Vehicles with Additional Upgrades
I. Downpipes
II. Air Intakes

If you have other upgrades on your vehicle (downpipes, intake, etc,.), the following information may be useful:

I. Downpipes: This upgrade may induce boost spiking due to the elimination of back-pressure in the exhaust system. It is recommended that you leave the default torque settings alone until a downpipe-specific map is supplied by us.

II. Upgraded intakes: Direct replacement ITG air filters have been shown to be worth 7-10whp over the stock unit when running v2.0.2. It is a worthwhile upgrade. We have them in stock. If you want one, call us Cone filters have been shown to be worth even more power at the expense of extra induction noise and a non-stock underhood appearance. We have a system under development
Thank you that work lawdude. Excellent job and we'll run with it Also big thanks to everyone else who provided feedback. I would post the new map today but tomorrow in Sunday and we'd like to take a day off. So expect the 6MT map to be online on Monday barring any forum drama.

Cheers,
shiv

In the User Adjustable Settings section you write:
"The maximum allowable boost, at full throttle, should be no greater than 14-14.5psi at 5500RPM."

But then a couple sentences later say:
"To achieve the maximum allowable 14.5-15psi at 5500RPM, you may ultimately end up with 94-96% across the board."

I take it 15 psi is really the max, not 14.5?
I have a range simply because boost will depend on gear, temp and altitude. And in the case of us 91oct folks, it may be best to err on the conservative side (13-14psi). At least until you get more miles on the car and make sure runs strong and consistently given the fuel you use and the conditions you drive in.

Quote:
2. You say the default settings are 90% across the board which gives a maximum of 13 psi. Isn't that less than v1.47 and if so, how do you get more rwhp on v2.02 than v1.47 with less boost?
v1.47 didn't run 13psi at high rpm. By 5500, it was down to approx 11-12psi. And by 6000rpm, it was running just 10psi. Even on the conservative default settings, v2.0.2 will be noticeably faster than any v1.x.

Quote:
3. You said that the default settings are "very conservative" and can be run on 91 Octane. But also stated that the default settings are for guys running 93 Octane too.
Would people that run 93 Octane safely be able to bump up the settings by 2% across the board and reap even more power benefits of the 93 Octane and still be a bit on the safe and conservative side?
The official answer is NO. At least for now

Quote:
4. Is the default settings conservative enough that if I got a bad batch of 91 Octane (that might really only be 90.5 Octane) or I have no other choice but to run some ARCO gas because it's the only gas station within 20 miles (if I'm on a road trip) and I'm low on gas, I won't have to worry about any issues?
I can't really answer that for sure. It depends on how bad the batch is. I don't think you'll have to worry about much if you are on the default settings. If you get bad or questionable gas, just go easy on the throttle or run the valet map until you get good gas.

Quote:
5. Regarding the ITG direct filter replacement. You said they have been shown to be worth 7-10whp with v2.02
Is that tested by you on the dyno you use or them?
I have the K&N air filter in. Do you suspect that is also the case with the K&N too?
Yep, we have tested it on our car. Worth 7-10whp at least. Especially if you have a dirty stock air filter as most of you guys in LA do after the fires.

Big assumption to make AT version is done. Has been for some time. And it's already been running in a bunch of local cars. Just want to make sure all questions/queries are answered with MT guys before adding ATs into the mix. It can get confusing since both cars require different tuning methodologies. So, to answer your question, I'm hoping that all MT guys will be sorted out by the end of the week at which point I'll post up 6AT maps. Nothing excessively tricky with the map update. But seeing how quickly drama builds, polls start, claims are made, I just want to slow things down for the sake of clarity.

Depends on your definitions of aesthetically integrated.

I put mine in the glove box since I do not care to disturb the interior look. I can open the glove box the rare times I need to.

Hey Shiv, I've been running 2.0.1 with the tq setting at 100% across the board for a few weeks now. I'll keep the initial default settings on the new map, but my question is, what should the setting be at on the new map if I wanted it to equal the power that I currently have or will it already?

How in the world are you running 100 on 91 octane. Wow.

I cant even run the defaults , let alone higher and I run 93 octane.

I really cant answer that unfortunately. Too many variables. And I'd suggest going back to the baseline defaults with v2.0.1 unless you are running a race gas mix. Running higher boost doesn't necessarily make the care faster when/if the ECU is running less timing.

Next week, I'm going to post a 'how-to gauge performance using the PROcede logging software' instructional. It will make it easy to see if the changes one is inducing is helping or hurting. Takes guesswork out of the equation.

My question is similar. Im running default torque #s for 2.0.1 with no issues whatsoever. The boost gauge consistently reads 15.6-16psi when doing a max recal. When my wife watches the gauge it sticks around 14psi as I am building through the rpm range.

Is it worth my time to even install 2.0.2 if I have no issues?

To M3to335's point (knock on wood) I have had zero issues running with 100% across the board with 100 octane. Will we see any advantage using 2.0.2 maps?
