    I can see why there is so many FI M3s on this forum. When is your next race?

    Definitely. That is called a technicality. Some of us hope people can understand more than just X vs. X. For example, why X is what it is. That's fine. Think what you want. If you can't look at 7200 rpm vs. 8400 rpm and how the curve works I can't do anything for you. Essentially you have a smaller blower at peak matching what a larger blower did not make at peak. That's a giant disparity right there. How hasn't it? It makes more power EVERYWHERE in the powerband at similar boost. The TT's are whole different ballgame versus a Vortech blower. Guess you missed this? http://www.bimmerboost.com/content.php?4866-Centrifugal-supercharger-vs-Turbo-Gintani-E9X-M3-S65-V8-twin-turbo-kit-dyno-results-and-comparison-to-the-Gintani-supercharger-kit-at-the-same-7-5-psi-of-boost It's my business what I'm doing. You have seen a dyno and it tells you plenty. I'd rather just run people. You just sound basic.

    I'm learning about how, when, and why to reset different things. I don't want to just arbitrarily make changes or delete data without having valid reasons for doing so. My last message was an update for the purpose of documenting what I've done, the results, and to encourage others to chime in. After doing so much searching on this subject and finding useless or only partially helpful threads, one after another, I wanted to create a thread that not only helps me get my own questions answered, but also to create a useful thread that others will find when searching for the same information. Here's a good reference I found in another forum that discusses "Flashing, Learning, Resetting" the ECU, including a method for speeding up the fuel trim learning process, and doing it correctly. According to this other thread, learning only occurs when in 'closed loop' mode during slow and steady throttle movements. Otherwise, the ECU is in 'open loop' mode, and does not learn new fuel trims - it can only apply fuel trims learned previously when in closed loop mode. It goes on to state that if insufficient closed loop fuel trim data exists, the result can be a sluggish and hesitant car. That was more or less my experience with the Stage1 map before I learned this from the thread started by 'Chuck99' at ft86club. Once I did this procedure as outlined, the car responded much differently - throttle response was much smoother, and the sudden bursts of acceleration were also smoothed out for a more drivable power curve. A personality change essentially. Now, I'm interested in the v8bait map, and what the recorded data means. I drove the car just after flashing without doing any resets, slowly accelerating from 2000 to 5000 rpms in 1st-3rd gears. Behavior seems good to me, but I question the Cyl 1 timing figures (show in above screen shots) because they were so much different than what I was getting using the Stage1 map after resetting and proper fuel trim learning. This is a partial quote from Chuck99's thread, with a link: "http://www.ft86club {dot com}/forums/showthread.php?t=68328" "Minimizing issues and speeding up learning after a Flash or ECU Reset As the ECU is reset as part of the flash process all the learned ignition and fueling parameters are reset. The ECU will also perform some diagnostics and calibrations on the VVT cam sensors and throttle position sensors after a reset or flash. To minimize any issues and speed up learning after a Flash or Reset Turn ignition fully off after a flash or reset Turn ignition fully ON, do not start car, do not touch throttle, leave for 20 sec this will allow ECU to perform its diagnostics and calibrations on cam position and throttle position sensors Turn off ignition Turn on ignition leave for 20 sec then start car do not touch throttle Let car idle for at least a minute and wait till it settles at the normal idle of about 750 RPM, again do not touch throttle. After normal idle is achieved then drive car. Fuel Trim Learning To speed up learning of fuel trims you will need to drive smoothly. The ECU only learns fuel trims in “Closed loop “ mode this is during slow or steady throttle movements and cruise and idle. When your driving aggressively on/off throttle and wide open throttle the ECU is in “open loop” fueling mode and does not learn fuel trims, it just applies the fuel trims learned in “closed loop” fueling mode. If the ECU has not had enough learning time in closed loop it will apply incorrect fuel trims and car may feel sluggish or hesitant till it learns. If your MAF has been scaled correctly hence reducing fuel trims to less than around 2% this learning process is very quick or not needed. Even with stock intake components the MAF scaling can be out by around 8% in places if individual MAF scaling has not been done, more if you have changed intakes and not re-scaled MAF. Vishnu Reset -Trick Yes you can google it :-) Basically it speed's learning of Fuel Trims and will Reset you IAM to 1 if it has dropped due previous knock events (assuming its not knocking at low/steady loads if so you have serious knock problems). If you do 2 or 3 "vishnu reset" runs ie partial light (20% or so) steady throttle runs from 2000-5000rpm or so in 3rd it will set your fuel trims and reset your IAM (assuming is not knocking at low/steady loads) if its less than 1. The gear is not really important its the partial steady throttle the longer the run the better. A slight uphill grade can be useful (or you can left foot brake). This works anytime to reset IAM back to 1 (assuming its not knocking at light load) it useful when your chasing knock in an area and want IAM back to 1 without an ECU reset."

    SCGT replied to a thread Properly sizing PI injectors in N54
    Pulsations are a pain in the ass to deal with. One of the real issues is that the equipment isn't high enough resolution to capture the true peaks and valleys going on. System piping is a huge cause, any step increases that are greater than about a 7* tapering change will look like a brick wall to the pressure wave. Bad. The injector events are going to want to cause pulsations; you're removing fluid, then slamming that "valve" (i.e. injector) shut. Batch firing is only going to make this worse, intuitively, as you're now opening/closing 6 little valves. The question is if this is really worth solving. Smoothing things out sure can make a difference in weird little things like random misfires or pump longevity, etc. Still, it'd be very easy to turn this into a science project with little obvious benefit. IMO all part of proper design -get it reasonable and honestly don't bother to strive for perfection on a system like this as it's not worth a hell of a lot more than "pretty good". If it were me, I'd start small and easy, like using a restrictive tapered orifice in the fuel rail inlet. You're not flow limited so who cares. Shy of that I'd consider the use of an expansion chamber somewhere along the fuel line, a sudden diameter increase and decrease at least 8x that of the fuel line diameter. That's no easier on the pump but it is easier on the piping. Any of the small in line or "tee" pulsation dampers will not work. The pressure wave is going too fast (mach 5) and will cruise right by it unless you fool around with geometry. That's my 2c input for now.

    Well until someone puts out a higher ready dynograph it will be known as the record. That is how records work. Claiming yours should put out more is only that, a claim. No proof, just words. The Gintani TT should put out better numbers than both. But it hasn't. Which is why it is not a record, and just a claim or as you would say "It doesn't take a genius to go look at the turbo specs." Why will no one ever see a dyno of your car? Why the secret? When will your car will run at an event? Someone sounds like they have sand in their vagina.

    Ferrari obviously made big waves when they turbocharged their V8's. This led to speculation if Ferrari's high revving naturally aspirated F140 V12 engine that sees duty in the FF, 599, F12 Berlinetta, Enzo, and LaFerrari would also get a pair of turbochargers. It appears it will not as Ferrari will focus on hybrid power instead to supplant the torque turbos offer. Electric motors obviously deliver their torque instantly and the linear fashion in which they do so likely suits the power delivery and response Ferrari is going for. A Ferrari source stated, “There will be no turbos on our V12s. Expect instead to see 48-volt systems on the next generation.” Who is that source? Autocar does not specify who it is only that it is supposedly someone 'close' to the factory. That could mean anything and anyone. It could also make this all meaningless as there is no way to verify it. It is likely true but who knows at this stage. We will definitely be seeing more hybrid Ferrari vehicles in the future. Source

    Look man, this isn't about my car. This isn't about me. I pushed things to 24 psi if you must know. This thing isn't near a YSI M3 at 18 psi. It doesn't take a genius to go look at the blower specs. All this happens to be is an exercise is trying to eek out a few numbers on a graph to impress idiots who do not know any better by exceeding numbers my car put down ages ago without even revving out. Then they can claim some irrelevant record and wave their pricks around the forums. It impresses people like bobS you see. It's nice to see more built motor setups out there but this is nothing more than your basic ESS kit with boost turned up + headers on race gas on a low compression motor. Wow, they really pushed the limit! New heights being hit on the S65! Amazing omgomgomgogmg wowzer. Top notch engineering. Seriously, the engine builder and ARH deserve most of the credit here. It's unfortunate that back then I was not able to get a clean dyno run on the stock DCT. I don't know why things do not go smoothly but maybe that is the way it has to be. If people want to think this is a 'new' record they can go right ahead and do so.

    Earth shattering power. Unfortunately I never reached 18 psi on the dyno. Wish I had a manual for dyno records. Go ahead and turn it up to 18 psi. Let's see it! What's stopping you? Yeah the V3si is amazing. AMAZING.

    These are two performance sport utility vehicles that do have similarities. They are German, turbocharged, all wheel drive, and both feature dual clutch transmissions. Beyond that though we are talking very different vehicles as the GLA45 AMG is essentially based on a front wheel drive sedan platform. That of course being the CLA-Class. The GLA45 AMG can be thought of as a CLA45 AMG on stilts. The test numbers show the GLA45 AMG matches its sibling pretty much across the board. That includes in curb weight as the GLA45 weighs only 3589 pounds. The GLA45 AMG also features the M133 2.0 liter four-cylinder AMG engine. With 355 horsepower and 332 lb-ft of torque it is no slouch and capable of high 12's in the 1/4 mile in stock form. The Macan Turbo though has a 3.6 liter twin turbo V6. The engine is less stressed and puts out more horsepower and torque in stock form. 400 horsepower and 406 lb-ft of torque. It's bigger, heavier (roughly 4500 pounds), more powerful, and more expensive. Would the 340 horsepower 3.0 liter twin turbo V6 Macan S that starts at $49,900 make more sense for this comparison? If you are trying to level the playing field a bit, yes. But even so the Macan S and Turbo are larger vehicles. The GLK is closer to size of the Macan. Regardless, this comparison pits these two together and is what it is. The straightline testing has the Macan Turbo come up with the quicker 0-60 at 4.2 seconds to the GLA45 AMG 4.3. The 1/4 mile result though favors the GLA45 AMG as the Macan Turbo manages 12.9 @ 106.2 whereas the GLA45 AMG does the 1/4 mile sprint in 12.8 @ 107.9. There is something to be said for power to weight but it is highly impressive the GLA45 AMG is quicker and faster in a straight line. Especially when one considers it has two less cylinders and has a 1.6 liter displacement penalty. To test the handling prowess they closed off a section of a canyon road. It is not super scientific but the GLA45 AMG comes out just ahead by less than a tenth of a second. The GLA45 AMG is lighter, more tossable, and offers a bit more steering feedback but the Macan Turbo does very well. It's practically a wash. MotorTrend picks the GLA45 AMG. If you want the vehicle that is more fun to drive that is the choice. If you want more utility the Macan Turbo is the choice. Considering the GLA45 AMG bang for the buck it is hard to argue against it here.
