There is a new firmware version for the I/O Extender (which adds to another recent release: V0.1.1) and for the TinyIOx. There are many new features and all users should have a look.

There is an updated version of the Peak&Hold Injector Driver Board that is used as an external driver box. This is a revised version of the V2.0 board which is now the V2.0.1 version available here. This board has 4 injector drivers and can be used directly with the MS3X injector outputs (among others). For an 8 cylinder engine running sequential injection, 2 kits are needed.

There hasn't been any update to this news section in a long time. However, there has been a lot of things that have happened in the mean time. I won't list them all because I would certainly miss a lot but hopefully it will be kept current in the future. The forum is always a good place to stay current as everything is announced there.

The I/O Extender board is now available. Due to the limited run, I haven't yet put a Paypal button on the web page so you'll have to contact me directly. For more information go to the I/O Extender web page or the forum.

There is now a forum available to discuss anything related to the jbperf.com boards. If you have any question, comment, request, post it on the forum and we can start discussing about it. The forum is here.

Glen's Garage now has the JimStim available as a complete kit and fully assembled. A preview of the V2.0 P&H board is available here. This will not replace the V1.1A board but will be another option for those who want a stand-alone solution in a separate box.

The P&H board has been successfully installed on a VEMS ECU. For more details have a look at Sprocket's wiki. This could also open the door for the use of the P&H board with the v3.57 board.

The Peak&Hold Board V1.1A is now available. The V1.1A board is essentially the same board as the V1.1 board but has 4 mounting holes to allow different options for board installation. It has the same features and components as the V1.1 board.

DIYAutoTune has added the assembled JimStim to their products.

Tuesday, 25 September 2007 at 16:34 EDT, by Jean Bélanger

The JimStim is now available as a complete kit from DIYAutotune. Click here for more details. I will continue to have the partial kit available for those who prefer it and those who want to buy it together with another one of my boards.

This is a quick attempt at regrouping all the information about the boards I offer. It is still very much in construction. It basically just regroups the information I already had into a single more easily navigated site. I will update the site as time allows.




Peak&Hold Injector Driver Board

This is a small board that fits into the last slot of the top half of the standard MegaSquirt enlosure. It can drive up to 4 low-impedance injectors.

bare v1.1 board

Signal Interceptor Board (breakout board)

This board allows all the signals coming into and out of the MegaSquirt to be analyzed and/or interrupted. this board can be used either while bench testing or on a running engine for installation diagnostics.

bare v1.1 board

JimStim - The Megasquirt Stim with a Wheel Simulator

This is a new version of the stimulator originally designed by James Murray (jsmcortina on the forums) that expands on the original stim's features. The main improvement comes with the addition of a microcontroller which allows the simulation of up to 30 different toothed wheels in addition to the standard distributor signal of the old stim. At the moment, there are 23 programmed wheel patterns but the firmware is upgradable using a specific USB cable made by FTDI (see BOM).

assembled v1.0 board

Dual VR Conditioners Board

This is a small board (with the same footprint as the p&h board) that fits into the last slot of either half of the standard MegaSquirt enlosure. It has 2 VR conditioner circuits using LM1815s and 4 ADC conditioner circuits.

Dual VR v1.0 board

PWM Converter Board

This small board is for those needing a faster PWM frequency for their FIDLE or boost controller than the ones provided by the current code versions. It has a CPU which reads the original PWM signal and generates a new PWM signal with the same duty cycle and precision but with a higher frequency. The new frequency can 2, 4, 8, 16, 32, 64, 128, or 256 time faster than the original signal.

bare v1.0 board

4-Channel Ignition/Injection Driver Board

This board combines 4 injector drivers, 4 ignition drivers, and one DB15 connector to clean up the wiring inside of the MegaSquirt case when using additional injector drivers with the new MS2/Extra sequential code. It can also be used for the ignition drivers and connector with any other MS2/Extra code version. It has the advantage of isolating all the high current devices from the main MS board and therefore reducing electrical noise to a minimum.
