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)
4 spare digital on/off inputs

2 knock sensor inputs
RS232, USB 2.0, and CAN communication
Onboard 8 gigabyte SD card for internal data logging
Internal ECU temperature sensor
Real time clock
Temperature range: -30 to +80 degrees C (-40 to +85 without battery for real time clock)

Software features:

Supports speed density, alpha-N, or MAF based fuel and spark tables
1 microsecond injector pulse width resolution
Tables for nonlinear injector behavior at small pulse widths
Allows blending multiple load types, including specialized mode for independent throttle bodies
Supports a wide variety of OEM cam and crank position sensors
Individual cylinder trim tables for fuel and ignition
Accelerator pump or model based acceleration enrichment
Closed or open loop idle speed control
Closed or open loop boost control with gear or speed based tuning options
On/off or closed loop continuously variable valve timing control – supports up to 4 channels
On/off or progressive nitrous control
Traction control
Rally anti-lag
Rotary support – can run up to 4 rotor engines with separate leading and trailing spark tables
Staged injection
Table switching
16 x 16 fuel and spark tables – can be reconfigured to function as 30 x 16 or 16 x 30 by switching tables based on RPM or load
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!

Has it really been that long??

December 18, 2011

I’ve been busy but never *this* busy! It’s been awhile since I’ve updated to the site so over the next few weeks look for some page updates and some new content.

Current shipping time on MS ECU’s is 3-4wk for new orders. Custom harnesses are on indefinite back order until I clear up some time to work on them. Std flying lead harnesses are unaffected and will ship with ECU purchases.

The KPTuned GTI is still moving along, although slowly. Sometimes you have to wait to get the best… more on that later!

Anyway, thanks to those who visit for hanging in there and we’ll be back with more shortly.

Stay KPTuned!

KPTuned ALL MOTOR GTI – 2011 Re-Build

April 26, 2011

Finally taking the time to work on the car, and find time for some updates here at!

So, what the heck is going on over at We’ve been churning out Megasquirt(R) standalone systems one after another.. tuning cars both in person and over electronic means.. and had a little boy adding to the KPTuned family, all of which is keeping us QUITE busy!

The KPTuned ALLMOTOR GTI had a good, but short run with the 3.2 R32 based motor. Unfortunately, it’s moved on, destined for another car that we’ll be doing all the wiring and an MS3/3x install on. With added complexity of a full engine bay shave, and wire tuck… stay tuned for and update of that one as it gets built.

The current plan for the car is to go back to ‘simple’ a bit, but change things up at the same time. I’m throwing a 12v together with spare parts trying to take out the ‘spray’ record.. if I can find one. Goals for the car are just to keep it light, keep it together, and keep it (relatively) cheap. 2150lbs is the weight goal we want to make, and make enough power to go 11.50 flat no matter what. It will feature a slick KPTuned Megasquirt ECU setup utilizing MS3/3x (of course?) along with Jean Belanger’s Jbperf IO/X board for additional I/O like individual cylinder EGT, dual WBo2 over serial communications, and some other sensors and outputs we’d like to try like dual water temp sensors, closed loop electric waterpump and fan control. One goal is to help develop a more integrated electronic dashboard as well…

The KPTuned ALLMOTOR GTI is getting some much needed attention in the fabrication department, with great thanks to Jim @ Racecraft Fabrication in Millville, NJ. I’ve known Jim for quite a long time and there’s no other I’d trust to make my parts! You might remember him from previous updates, he did the manifold welding on Derek Baker’s “KPTuned” ITB’d VR6 MK2 GLI. This time around, Jim’s being tasked to build a KPTuned rough designed intake manifold (to our exacting specs!), large tube downpipe with Burns Vband collector, proper seat mounts, and finally a proper crossmember with traction bar mounts and all our accessory items integrated in. Luckily Kurtis @ MBS already came through with a killer 3.5″ full aluminum exhaust, with integrated v-bands, and Magnaflow muffler. Should make the rest of the fab go nice and quick!

Now for the pictures!!

Lots of pan clearance, thank you OEM Mk5 junk…

New exhaust thanks to Kurtis @ MBS

MY way to mount 02J shifter

He’s got a lot of parts and much work to do…

Stay KPTuned for further details as things come together.

Back, Back, Back!!

August 4, 2010

Site has been down for a bit, and I accidentally lost some data. I’ll have it back in the next week or so.

In the meantime just a quick update from Waterfest ran a 12.90@106 at 2500lbs with the new engine setup with LOTS of room for improvement.

We’re back!

December 11, 2009

Ok, honestly we have been for a few days now, but we’re just getting all caught up. It’ll take us a little bit of time to get to 100% but some space has been cleared for our electronics lab and it’s all back up and running. We’ll be a little bit longer to take installs but it’s all in process right now. Again, thanks to everyone for being patient with our communications black out during the move.

KPTuned is moving!

November 18, 2009

KPTuned is happy to announce that we’re moving. Along with a new personal property will come a new larger space for Megasquirt system assembly, repair, development and testing. We will also have much more room for installs, which has been a big limitation for us over the last few years.

The new address will be:
105 Sunset Rd
Oxford, PA 19363

Please DO NOT send anything to us for modification/repair without speaking to us first!

Due to the move we will be closed from 11/25-12/2 and have limited internet usage during that time. Stay tuned for further updates!
