If you've added a supercharger or turbocharger to the engine you'll need to adjust this limit to be a bit above the amount of boost you want to run. When the threshold is reached, injector PW pulse width will be cut to 0 for a split second until MAP manifold pressure drops back below the limit if overboost protection is turned on and configured to fuel cut, which is typically how it would be setup. Therefore with the default settings on a factory naturally aspirated vehicle, if you try to boost too near to kPa you will feel the engine cut out when Overboost Protection kicks in.
This can feel like a single cut, or it can feel like the car is erratically cutting out and bucking if you stay on the throttle and continue to bounce off the limiter. The Hysteresis value lets you determine how far the boost pressure has to drop before the overboost protection is turned off allowing the injectors to fire again.
This kpa Overboost Protection limit, and the hysteresis, are very easy to configure in the tuning software on the Overboost Protection dialog under the Extended Menu in TunerStudio MS.
NOTE-- for factory forced induction cars supercharger or turbo the default boost cut limit will vary by model. Tuning is the same as above. Once you have wired this up, you can enable boost control in TunerStudio. In open loop mode, the boost control solenoid puts out a signal at a fixed duty cycle that is, a percentage of time the solenoid is open as a function of RPM and the throttle position sensor.
This is a bit easier to tune and will generally keep the boost right where you set it, but can drift a psi or two with dramatic changes in air temperature and other variables.
You'd be most likely to notice this if for instance you had tuned the car on a 80degF day for 15psi of boost, then drove it on the 32degF day. In that case you might see an extra pound or two of boost. Closed loop boost control is a bit more complicated to tune, but when properly setup allows the ECU target and correct to a specific boost pressure regardless of ambient air temps and other variables that come into play.
This is the valve we have tested with, and have setup the base maps to support by default. When running boost control, you'll set up the basic parameters for the valve under the Boost Control screen in the Advanced menu. For our EBC solenoid, we recommend a frequency of The boost control pin is always PA0. The Output Polarity setting is Normal. The duty cycles can be a little confusing at first glance: They refer to waste gate opening, not solenoid opening.
If you're using open loop boost control, you'll next need to tune the 'Boost Duty Target' table. Burn this and try it. See if your boost increases ANY at all over your waste gate only boost levels.
Burn it and test it. Datalog this and compare how much boost you made to the prior pull. The pulls need to be in the same gear with all conditions identical, preferably on a dyno, though a track could work if you have a long consistent straight that you can pull 3rd or 4th gear from before the turbo spools maybe rpm on up to redline, repeatedly, in a safe environment.
You're looking for when you start making more boost. When you do then you can start fine tuning at different RPM ranges. Adding a little more here, pulling a little out there, moving around the RPM columns to make it do what you want it to do, reviewing your logs in MegaLogViewer to see what the results of each pull are.
That's an attempt at making the turbo spool as fast as possible. The GT turbo in our 91 Miata shop car is fully spooled to In order to keep it from spiking though we had to bring the duty cycle way down to 45 by rpm, then after that we just 'gave it what it needed' to keep the boost at about You can see in this table at higher revs it took less DC as the turbo was wanting to make more boost so we had to pull the boost controller back some to control it.
Bottom line, start at low duty cycles, make small changes, and analyze the results of each pull. Remember that as you add boost you're getting into previously untuned areas of your fuel and spark tables and you'll need to adjust those as you go. If your car has a variable TPS throttle position sensor then you can also adjust open loop boost duty cycle based on throttle position, making the waste gate increase or decrease boost at lower throttle positions.
Typically you'd reduce DC at lower throttle positions, such as in the cruising speed range where you don't want the turbo boosting to the moon. We recommend tuning the open loop boost control before you attempt to tune closed loop boost control. To tune closed loop boost control, first set up the boost control target table. You will enter the desired kPa reading as a function of throttle position and RPM. You should not enter in any values lower than waste gate pressure as the valve cannot reduce boost any further, your mechanical wastegate's pressure is the baseline and can only be added to by electronic boost control.
We'd recommend starting to tune CLEBC closed loop electronic boost control at a lower boost pressure than you ultimately intend to run. This will allow you to get a handle on tuning this feature prior to running more serious pressures. Before you start, make sure you've adjusted your VE and ignition tables conservatively around and above the boost pressures you are targeting, that means keep the fuel a bit richer than you expect to need, and the ignition a bit retarded from where you expect it to be.
If the boost overshoots above its target get out of the loud pedal quickly, and increase the proportional gain. If it does not spike, you may reduce the proportional gain until you get just a very small amount of overshoot. Leave the proportional gain there. At this point, the boost is likely to creep up slowly after reaching the target. Add a bit more integral gain until the boost stays on target, then increase differential gain until you have minimal overshoot when the turbo first spools up.
At this point the boost should track right along with the target boost pressure you've set your MSPNP2 to target. TunerStudio can log the MSPNP2's input and output readings to help you dial in your tune, and it can also be a great diagnostic tool. You can activate this by pressing Alt-L or going to the Datalogging menu and selecting Start Logging. You will be prompted to enter a file name and save it. TunerStudio will start recording after you save the file, and continue saving a data log until you close TunerStudio or turn the logging off.
You can then play back these logs with MegaLogViewer to see if your tuning delivers the right air-fuel ratios throughout the RPM range, to monitor commanded ignition timing through the pull, or any number of variables that can help you properly tune your engine.
Your MSPNP2 is equipped with an adjustable knock circuit with a built-in audio output to listen to the knock sensor similar to a set of detcans. There are a total of four adjustment points accessible by removing the top cover. See the jumper diagram at the bottom of Section 3 above for locations of these. The "Volume" adjustment is only for the headphones; it will not affect any of the other settings. This adjusts the headphone volume. The sound on the headphones has been run through a band pass filter to remove much of the engine background noise.
This also affects how knock sounds as it is centered on the fundamental knock frequency. You will not hear a "rocks in a coffee can" type sound if the engine is knocking. Instead, the sound will be more like a very high pitched ringing, chirping, or scratching sound. Clockwise increases the volume, be very careful with this as it may need to be adjusted to work properly with the headphones you use, and is capable of a fairly loud volume level depending on your headphones.
The circuit works by generating a threshold voltage based on RPM, and seeing if the signal from the knock sensor goes over the voltage. The "Gain" adjustment knob lets you amplify the signal before it is compared to a threshold voltage. Turning the knob clockwise increases the amplification.
The threshold voltage can be measured by checking the "Threshold" test point on the board, but it can also be read through TunerStudio. Here is how we recommend adjusting the knock threshold on a dyno. Inside the case, place the jumper 15 See jumper tabel above in the "Test" position to the right. This gauge will give you your threshold voltage. This gauge will give you the peak voltage reported by the knock sensor.
Set the spark table to a conservative value that is known not to produce knock. If at any point you hear it knocking during this test through the headphone jack, reduce the spark advance further. You will want to keep the ADC6 gauge just a little under the value reported on the ADC7 gauge - the closer they are together, the more sensitive the system will be to knock, although getting them too close together or having ADC6 exceed ADC7 will result in false knock readings.
Inside the case, place the jumper at JS6 back in the "Run" position to the left. Re-enable knock sensing and real time barometric correction. However, dyno time is very expensive diagnostic time - you want to have your car sorted before you go. You don't want to show up to the dyno with your MSPNP2 in the box along with your set of cc injectors and new boost controller Go ahead and get the car running on the configuration you'll be tuning before you get there unless you are planning to pay the shop to do all of this for you, in which case you're probably dropping the car off so they can schedule the work.
If you're removing the AFM, go ahead and do that as a separate stage as well, testing afterwards. The idea is to make only one change at a time, so that if there is an issue somewhere you know where to start looking.
Pre-Dyno Maintenance: Make sure there are no leaks, you've got fresh oil, fresh plugs and good wires, your air filter is clean, etc. A full tank of fresh fuel helps too.
You should probably also gap them a bit tighter than stock. You wouldn't believe how many people get their car to the dyno and aren't ready to have their car on the dyno! Be ready!
Also turn Enhanced Acceleration Enrichment off. These can be set back to their defaults after tuning. Loading it into each cell and tuning fuel first, and then doing the same tuning ignition, finally tuning higher throttle doing ramp runs on up to WOT ramp runs.
That's our preferred method anyways, your tuner will have their own plan but this is what we consider to be the proper order of things. Cranking PW, Warm-up Enrichments, and After Start Enrichments could need fine tuning as well though they are probably close enough to serve you pretty well without adjustment. In some cases, it may be easier to fine tune this while actually cruising with the actual load you'll have on the car in a real life cruise situation.
You'll be looking for good gas mileage and drivability here while minimizing emissions. Ignore it at your own peril. These are in no particular order, so please read them all! The MSPNP2 is not designed to control emissions equipment and is not intended for use on pollution controlled vehicles. If you ever need, or choose, to upgrade or reload your firmware this is very important. Leaving the coil and ignitor connected when loading code can possibly damage these components.
If either of these is disconnected the ignitor and coil will be safe during reflash. Since the MSN TV 2 utilizes more powerful hardware and software compared to its predecessors, it introduced many improvements and new features, which include but aren't limited to:. Photo, video, and music playback can also be used while offline, but those require the box to have already been subscribed and logged in to the MSN TV service. What songs were offered by the service for the latter feature is currently unknown.
E-mail us by using the link on this wiki's sidebar to get in touch with us if you have any information on this. Starting in the mid s, it appears that at one point in time, almost everyone and their grandma could buy an MSN TV 2 unit second-hand from any auction site, such as eBay, for cheap.
The reason for them being sold for cheap at the time isn't exactly easy to guess, but with the discovery of being able to hack the units into cheap Linux boxes, it helped make the cost of performing it quite affordable.
Nowadays however, it appears as if MSN TV 2 units are simply more rare to find, with 1 or 2 new listings popping up once in a blue moon on eBay at least. Other than that, the most the MSN TV 2 got in terms of hacks was being able to run Linux on it, which is a feat in itself, although methods to do this as of writing involve files you can't easily get anymore, and they may not work with more modern versions of the Linux kernel.
