KPTuned ALL MOTOR Corrado – Almost Ready!

July 18, 2016

Trying to debut at Waterfest this weekend but ran into a few mechanical issues we don’t have time to address. Will keep plugging away in the meantime, but very happy with MS3-Pro controlling, Microsquirt I/O and CAN-EGT measuring and Racepak IQ3s Display!




New Support Package and Remote Tuning Pricing

January 18, 2016

With the uptake in remote tuning and support customers we are rolling out a new pricing strategy for those users. It is the exact same setup and tuning support we offer for our ECU customers, but accounts for the extra challenges that come with new relationships.

Support package for MS3 based ECU setups, including MS3-Pro and GoldBox: $300

Support package for MS2 based ECU setups, including Microsquirt: $200

We will be setting up a webstore for the off the shelf purchases including these pretty soon. In the meantime, email us for details.

Transitioning Products to PRO Units

June 30, 2015

Over the next few months we will be phasing out our in-house assembled options to further support the development of Microsquirt and MS3-Pro units. After doing many sales and installs these units provide the best long term value to the end-user. Moving away from assembly will allow us some extra time to focus on custom Microsquirt and MS3 based units for specific applications as well as a few other products we’d like to offer in the future. We will continue to support all existing installations, as well as offer new support packages with all our new products as they become available.

As always we’re a distributor and rabid supporter of the guys at DIYAutotune and will continue to use them as well as other reputable vendors for our lines in the future.


We will continue to have our repair services as long as they continue to make sense. Please contact us in advance for RMA authorization prior to shipment.


Stay KPTuned for further information!

It HAS been awhile!!

December 3, 2013

It’s been quite a long time since our last update, and shame on me! Keeping busy with life, working, and keeping my customers happy in this last year. Orders for MS3 variants have been coming strong, and with the MS3/3x unit’s setup and configuration is always key to getting people up and running as quickly as possible.


In the near future we will be offering different support packages for the MS3-Pro units to complement what we have done in the past with MS1, 2 and 3 units. Likely we will be offering a web-store for these units as they can be easily configured by the user after wiring is complete. We will still be offering all the kit built variants on a personal-order basis for the time being.

The KPTuned GTI VR6 project is coming along, although slowly. Look for an update around the holidays.

As always we welcome and appreciate all the business that our customers throw our way, and we’re really thankful this holiday season for all the friends we have made along the way. THANK YOU!

DIYAutotune Launches MS3-Pro ECU!

January 2, 2013

From our friends over at DIYAutotune –

“The MS3-Pro combines the features of the legacy MegaSquirt-3 with all available ‘expansions’ built right into a single circuit board in a sealed case. The o-ringed case is splashproof and, if you want continuous immersion resistance (the MS3-Pro displayed at PRI was at the bottom of a fish tank), it’s easy to add a bead of silicone for extra protection. Furthermote we’ve updated the power supply design to use a switching power supply to minimize energy consumption and maximize stability of operation (down to as little as 6v!). We also included the new intelligent knock sensor capability allowing for advanced knock windowing and noise threshold configuration, integrated internal SDCard datalogging with time stamping of all datalogs, USB and RS232 Serial tuning interfaces, individual cylinder tuning for fuel AND ignition timing to allow you to compensate for differentiation in flow characteristics to different cylinders and truly maximize engine output, and more!

The MS3-Pro is ready to support a wide variety of engines out of the box, with the ability to anything with one to eight cylinders with sequential fuel injection and sequential ‘coil on plug’ ignition, a V12 with sequential fuel and wasted spark ignition, or a four rotor Wankel with separate leading and trailing ignition outputs. Over 50 different ignition modes are supported, from mainstream applications like the GM LS1, Bosch Motronic, and Chrysler Gen III Hemis to unusual modes like Renix Jeeps and the Suzuki Swift GTI.

The MS3-Pro’s packaging is also a departure from most previous MegaSquirt EFI Systems. Instead of the industrial looking split aluminum case and D-sub connectors, the MS3-Pro uses a sealed high temperature nylon case for light weight and compact size, and heavy duty AMPSEAL connectors. This provides a compact and sealed enclosure protecting the sensitive internals from the elements. The MS3-Pro’s design keeps the heat generated to a minimum, allowing it to use a lighter plastic case instead of a metal heat sink.

Retail pricing for both the ECU and wiring harness will be under $1,200 and you can expect the MS3 Pro to hit the shelves by January 1, 2013!

Here is a complete list of the MS3-Pro’s features:

Hardware features:

Freescale MC9S12X 16 bit, 50 MHz asymmetrical dual core processor
10 saturated injector drivers
8 logic level ignition outputs
3 high current (5 amp) general purpose outputs – 2 can be reconfigured as additional injector drivers
3 medium current (3 amp), high frequency general purpose outputs
All unused injector and ignition outputs can be used as SPARE outputs. This ECU has a LOT of I/O!
1 stepper H-bridge driver
Camshaft and crankshaft differential inputs – supports VR, Hall effect, and optical input
12 volt tach output
Fuel pump output
8 analog inputs (5 dedicated sensor inputs, 3 spare/general purpose)

2 or 3 step rev limiter with no-lift shifting
Wideband AFR target tables
Flex fuel sensor input
Allows repurposing injector or ignition outputs as general purpose outputs, or high current outputs as injector drivers for 12 cylinder sequential applications
Real time barometric correction
A/C and cooling fan control with idle compensation
Safety shutdown based on AFR or EGT input
Sequential shift cut and air shifter control
6 General purpose on/off or PWM inputs

Although the current MS3-Pro is a universal, wire-in ECU, expects to follow up with several plug and play variations for 2013.

Of course we have had our hands on one already and have been very impressed with our unit so far. We should be getting some of them in stock shortly, stay tuned for pricing and additional information on this exciting innovation in the MS world!

Communication and juggling, what do they have in common?

December 28, 2011

Lots of balls?

Seriously though, as you can see from my last post (which was a long time coming!) there are more then a few things going on that I’m trying to make progress on.

  • Support of existing customers install and tuning
  • Meeting current orders in a reasonable period of time
  • Pre-sale support/Q&A
  • Tuning local and remote installs
  • Developing new products/innovation
  • VW Drag Racing program

Now that I wrote it down, I think that’s more then what it has seemed!! Each of those things requires some head space, and there are things that ALL of you can do to help me out:

  • Include history in your emails
  • When calling leave messages including call back numbers/email
  • Text messaging – include your name/contact info especially if you are a new customer or someone whom I don’t talk to regularly
  • Be patient – I get lots of calls, and when I do have free time at home it’s not always easy to call back due to ambient noise level (parents will understand that one!)

As always don’t hesitate to contact us, we will try to be as accommodating as possible. However, going a short way to help us help you, it will make information turns much quicker.

Again, thanks to all of our existing and future customers for their interest in KPTuned!
