  • bootmod3 - World's First BMW F series custom flash tuning platform - Android - iOS - Web

    Posted on November 01 2016

    bootmod3 - World's First BMW F series custom flash tuning platform - Android - iOS - Web
    Here at PTF we've worked tirelessly over the past 18 months to create the World's First factory ECU (DME) flash tuning platform for the BMW F series called bootmod3. Up until bootmod3 came into existence there were two popular ways of tuning the BMW F series, using a piggyback device to add boost and sending your ECU (DME) out for a one time flash to a tuner of your choice. With the piggyback the end user has partial control over the boost the car is running but no direct control over any other engine parameters such as ignition timing, lambda targets, fuel pressure...

  • 1000+hp Stock Motor 997.1 Turbo - Twin GTX3076 Turbos

    Posted on December 10 2015

    Thought we’d share some results from last night’s tuning session. This 997.1 Turbo was brought to our friend’s at Boost Theory in Mississauga for some custom fab work a while back. Along with some exterior aesthetic changes the car received a custom 3″ x-pipe exhaust, manifolds with Tial external wastegates that fit with Garrett GTX3076 turbos, 3.5″ intercoolers, custom y-pipe with Tial BOVs, ID1000 injectors and a Sachs 2.5 clutch. Stock plenum and throttle body are still on the car. Dyno for this particular car was at DL Motorsports who have just a single roller Dynojet so the front driveshaft...

  • Porsche 997.1 Turbo (2007-2009) Aquamist HFS-3 methanol injection kit – wiring diagram

    Posted on June 09 2015

    We have used methanol injection on almost all the platforms we’ve tuned since 2007 with great results. To do it properly one shouldn’t compromise and should use the highest quality injection kit with an appropriate turbine based flow sensor failsafe in place such as what comes in Aquamist’s HFS-3 and HFS-4 kits. For those looking to install a methanol kit on their 997.1 Turbo we recommend going with the Aquamist HFS-3 kit and you can order it here. Here’s a wiring diagram for the OEM DME harness. For any tuning related questions don’t hesitate to contact us at sales@protuningfreaks.com. NOTE: If...

  • PTF proTUNE Results, PUMP gas stock turbo record and comparison dynos with JB4 G5

    Posted on February 16 2015

    In almost every initial email people ask us what we can do for them with our custom tuning power wise. Some come to us with bone stock cars and ask about getting parts to go full bolt on and get a custom tune. Others come to us with an existing Cobb OTS tune and ask about gains while some already have a tune such as the latest JB4 G5 with and without the free BMS backend flash. We spent some time on the dyno and gathered up some neat results to demonstrate what we can do. The runs are on...

  • BMW N54 Boost Control – PID and Tuning Limits

    Posted on January 26 2015

    Given recent developments in flash based tuning we wanted to offer our insight into the inner workings of the N54 DME when it comes to boost control tuning or more specifically, PID based boost control. Boost control in the N54 OEM DME as well as most modern electronic boost controllers out there is based on what is called a PID algorithm. PID algorithms aren’t exclusive to boost control and are applied to various systems where correction to a signal can be applied by feeding the actual value of the signal through the algorithm and adjusting control for it automatically by...

  • New Porsche 997.1 Turbo 60-130mph record – 6.700secs on pump 93 octane – OEM turbos + boltons + PTF custom Cobb tune

    Posted on January 08 2015

    We are happy to report that a protune customer of ours from Alabama, US has just set new 997.1 OEM VTG turbo 60-130mph record at 6.700secs on pump 93 octane. The car has minimal bolton modifications including an AWE exhaust, OEM 997.2 intercoolers and do88.se turbo inlet pipes with a Sachs 2.5 clutch that drives just like the OEM clutch. This is your ultimate sleeper setup. The car has had ID1000 injectors as the car will be running on E85 soon. We’re looking forward to even faster numbers with E85!

    Posted on December 01 2014

    We’re excited to share a recent vbox verified 60-130mph time of 5.90secs done by our customer Costas in Greece that looks to be a new World Record. What really makes this impressive is the car is running pump gas with our custom Cobb protune and the only hardware modification being a 100cell exhaust. Congrats once again Costas!

  • BMW N54 30FF Underboost Code – Boost Leak Testing – DIY

    Posted on November 30 2014

    We decided to share this great DIY on boost leak testing that was contributed to the N54 community a long while back and is still very useful for those running into issues with underboost codes, limp mode due to a boost leak in their charge piping. —————— Spent a lot of time the past week trying to diagnose a 30FF. (Boost Log is NOT matching Target) Since 30FF can be from a leak in the pressurized section of the intake track and/or the turbo just isn’t putting out enough, I broke this up into 2 areas: 1.

  • 534WHP 532WTQ – One-off set of custom turbos from Vargas – Race Gas + Meth – New N54 Stock Frame Turbos/Stock Motor Record? We think so..

    Posted on August 19 2013

    Went back to the dyno this past Saturday. It was a lot hotter out than last time when the car did 523whp on pump+meth. With the same conditions as on the pump/meth runs it could’ve maybe done a touch better, maybe 540 even, maybe not. It shows just how close meth/pump numbers can be to a more expensive race gas+meth alternative when you’re already maxed on the turbo side of things. However, with race gas some additional timing managed to be had without knock through the top end helping power not drop off as quickly in the 6-7k rpm range....

  • 523WHP 520WTQ – BETA VTT Turbos – Pump gas and Methanol Injection

    Posted on August 16 2013

    Had some fun with a set of BETA VTT Stage 2 turbos on Wednesday night and here are the numbers. The tune is running 21psi peak down low, 20psi at 6k rpm, 19psi at 6200rpm, 18psi at 6500rpm, 16.6psi at redline. Timing is in the range of 10.5 to 11.5deg peak without any hint of timing corrections all the way through. This was on  pump 94 octane from Petro Canada (formerly Sunoco) running the Aquamist HFS-4 setup with two 1mm nozzles and 100% meth. According to short term trims the DME is pulling out 25% through trims with two 1mm...

  • Custom single turbo – 18-18.5psi – external wastegate control, OEM solenoids, COBB flash only – shakedown runs

    Posted on August 11 2013

    Wanted to share what I think is another key milestone in N54 tuning. Yesterday we managed to use Cobb to control an external Tial wastegate entirely, without piggyback involvement and make some good numbers. Boost control had to be redone from the typical way its done for internally wastegated vacuum operated turbos such as OEMs and any stock frame hybrids. We stopped at these numbers as the HPFP pressure literally nosedived near redline to 600psi from 2000+psi targeted so we’ll be looking at the usual fuel capacity boosters and a couple things that I haven’t heard of being tried yet....

  • Effect of Soft Snow Tires on Dyno Measurement Results

    Posted on February 09 2013

    We get this question quite often about the effect on dyno numbers with winter tires, namely: Does the soft compound, thick tread blocks, and high number of deep sipes used in a snow/ice tire affect how much torque/power a roller chassis dyno would measure? The answer is, Yes.  Here’s a great writeup, courtesy of Airboy Tuning, that was done on another platform but still very relevant showing why, if you’re after PEAK dyno numbers, you shouldn’t dyno on winter tires. Now, dyno tuning can still be done on any kind of a tire (as long as its not slipping on...

    Here’s a review from @VNeBLOB42, one of our recent customers on his PTF eTune on California 91 octane mixed with E85 to make an 50/50 mixture of ethanol to gasoline. The car’s only hardware power adding modifications are dual cone intake and intercooler.  This dyno reads about 17.5% lower than a typical Dynojet as its reading SAE and the car stock dynoed at only 231whp.

  • BMW N54 – Data Logging with COBB AP – Part 1

    Posted on July 18 2012

    Data logging is an invaluable tool when it comes to maintaining reliability and checking on your modified car. It allows you to know what your car is trying to do (requested values) and what your car is actually doing (actual values). Knowing the concepts is one thing – being able to understand it and utilize it is another. The most common question I get in regard to datalogging is people asking me what is useful to record when doing a pull. The good news is that Cobb setup the default logging parameters really well. It has just about everything you...
