The board is true plug and play. Just replace the PCB in your ECU with this board and drive the car. The hardware capabilities are defined by the microRusEFI module that drives the unit. See microRusEFI-Manual Your board should look something like this: Currently the only tested configuration is the NA6 Miata with a manual transmission. If you have a different car, we may need your help testing the configuration! Automatic transmission cars are not yet confirmed to work, although there's no reason to think they won't. The standard configuration runs the engine using the stock AFM (Air Flow Meter) to measure engine load. However, the AFM on early Miatas is an actual restriction in the intake and costs possibly as much as 3hp (this is a guess). It's also useless if you want to add boost to the car- the capability to measure airflow peters out well below the airflow capabilities of even a mild turbo or SC setup.\nThe 48 pin board can be equipped with one or two onboard MAP sensors. Alternatively you can also run an external MAP sensor or even a bigger AFM.\nThe board can be configured for several different options simply by adding/removing some simple SMD jumpers. More custom solutions can be achieved by adding wire jumpers. 1. Installation Open the stock ECU case Remove the stock PCB from the ECU case Install the rusEFI board in the ECU case (note: one of the mounting holes, labeled J27, requires a stack of 3 M4 washers- see image below) Close the case* Plug in connectors and drive *You may want to not put the lid on the case for now. That makes it easier to connect to the unit with a laptop using a micro USB cable. See below: USB connection. One of the mounting screws needs three M4 washers because the case has a recessed thread- the stock ECU has a heat sink at that location. The washers may be included with your kit. They go here: 2. Standard upgrades over stock The board should be received set up as a stock replacement unit for your year car. Either a 1990-1993 NA6 or a 1994/1995 NA8. Even in standard configuration it can perform a few tricks the stock ECU just can't. 2.1. USB connection The unit can connect to TunerStudio via native USB communication. You can either plug a MiniUSB\n(or some boards have MicroUSB) cable into the top of the unit. This is a bit difficult to get to in the stock installation position on an NA6, so it may not be ideal for a permanent installation in the stock location. If you want to use this connector for communication with your tuning laptop, cutting a hole in the top for connector access is helpful. Here are some rough dimensions on where the hole should go. A 5/16\" or 8mm drill and a small file or Dremel works well. Alternatively, you can wire a standard USB cable into the main connector for a more permanent solution. Your board may come with additional contacts / wires for the main connector that can be soldered to a standard USB cable. (Please note that the 5V connection is not needed for communication. It can, however be used to power the MRE unit with the ignition off. The 5V power suply feature is untested and may not work. Communication using GND, D+ and D- is confirmed to work.) USB COLOR PIN JUMPER 5V RED 2J JP36 GND BLACK 1I JP13 DATA + GREEN 1T JP24 DATA - WHITE 1S JP23 2.2. Micro SD card adapter The board comes with an adapter for a Micro SD card. Install a card in this slot and it will automatically keep a log of your engine when it's running.\nThe log can be retrieved using the rusEFI plugin in Tunerstudio. Please note that Tunerstudio must be offline for the plugin to have access to the USB port. If Tunerstudio is still communicating with the ECU (online), the rusEFI plugin will be unable to access the USB port.\nAnother way to retrieve logs from the SD card is to open the case, remove the SD card and read it directly from a computer or other device running MegaLogViewer. Warning: There are reports that some Micro SD cards will not work for this setup. So if you are having trouble with this, try a different card. 2.3. MAP Sensor Your board may, or may not, have an onboard MAP sensor. The onboard MAP sensor can either be used as a primary MAP sensor to supply the ECU with a load signal, or it can be used for barometric correction for units running an external MAP sensor. In order to use the internal MAP sensor to supply the ECU load signal you have to run a 3/16\" (5mm) vacuum hose from the intake manifold to the unit and drill a hole in the stock ECU case. (see picture below).\nThe board can be equipped with a secondary MAP sensor for barometric correction as well 2.4. Tach Signal Your stock engine (Miata NA6 and 94/95 NA8) uses external igniters that not only drive the ignition coils, they also provide the signal the tachometer uses to display rpm. The ECU provides only a pull-up to 5V. When equipping the vehicle with coils from a different generation Miata, or any other logic-level coil, like COPs or GM LS coils, they will not provide the tach signal and the rusEFI unit needs to take care of it. In the standard configuration the ECU only provides the pull-up resistor, but it can easily be changed to provide the tach signal. 3. Upgrades / expansions / options 3.1. Wideband O2 sensor This is so basic that you should probably do this at the same time as the installation of the ECU. Any aftermarket wideband sensors with an analog output will work. You will have to supply it with switched 12V from a decent source and connect to signal ground at the ECU. For the 12V you can splice into the wire going to pin 1B on the ECU (ignition power) and for ground rusEFI provides an additional signal ground pin on pin 2F that is not populated on the stock connector. Or you can splice into wires from pins 1C or 1D. The analog output should be connected to pin 2N on the ECU connector. This is the stock narrowband oxygen sensor input. 3.2. MAP Sensor The first thing most users will likely want to do is use a MAP sensor for load sensing instead of the stock VAF (AFM). The easiest way to achieve this is to install an MPX4250 in the designated spot on the PCB (see image). Your board may already have this sensor installed.\nWarning: V 0.2 of the board has an unintended \"feature\" that requires you to Note that only 4 of the six legs of the sensor get soldered directly to the board. Pin 1 and pin 3 get bent up by 90 degrees and wired into pin 3 and pin 1 of the ADJACENT barometric sensor. Note that pin 1 on the sensor goes to pin 3 on the board and pin 3 on the sensor goes to pin 1 on the board. Please make sure to upload the correct tune for this configuration or change your tune manually. Tunes can be found at rusEFI Online If you want to install an external MAP sensor, like a GM 3 bar sensor for example, you can wire it to your stock AFM connector instead of the AFM. Or you can run additional wires from the ECU. Instructions will follow separately. 3.3. TPS NA6 Miata with manual gearbox come with a throttle position switch that can recognize two positions- idle (closed) and full throttle. This works good enough, but if you really want to fine tune your engine, you may want to use an actual throttle position sensor. There are several popular options on how to achieve this. Either use a TPS from an automatic NA6 Miata. these do seem, however, be hard to get by these days. You can install an aftermarket throttle body with TPS, or you can install a TPS from a Kia (part numbers are 0K01118911, 0K24718911, 0K30A18911, TH291, 5S5504, TPS4185, TH0254, 1580486, 2001332). You need an adapter for this. The design can be found here Mazda NA6 Miata variable TPS mount Instructions on how to jumper the board for these configurations will be updated later. For now see this forum thread 4. Connections Expansions usually require some wiring. The standard pinout for the connector in NA6 configuration is this below. 5. Assemble your own If you just get the bare board with all the jumpers installed, there's some things you need to do. 5.1. MAP Sensor There are two positions for installing a MAP sensor on the board. The sensors used are MPX4250 . They should be secured with two screws each. 4-40 x 0.5 socket head cap screws are preferred. Of course, these screws will require some nuts . 6.

This is useful for cold start conditions where complete fuel burn may not occur from a single spark. During multi-spark the first ignition will be a partial burn and stir up the remaining fuel in the cylinder allowing subsequent burns to create a more complete fuel burn. Disclaimer Currently the mutli-spark in RusEFI is completely experimental and should only be used as such. The owner and user can use at their own risk to catostrophic damage to their ECU, engine, and vehicle. Working Theory During low speed operation if there is enough time for the dwell and ignition period of an ignition coil in a single power stroke the ECU can fire the ignition coil multiple times. The result of this will be a more complete fuel burn giving more power, better fuel economy, and lower emissions. The downside is that due to the ignition coil firing multiple times per power stroke the ignition coil will operate hotter possibly leading to overheating and lower ignition coil life spans. How-to Enable To enable multispark feature open the Controller tab in the options bar. In the drop down menu open the Multispark window. In the event that the Multispark option is greyed out spark will need to be enabled. Double check that under Ignition settings that Enabled is set to true in the drop down menu. If ignition is enabled then multispark settings should be available. In the Mutlispark menu to enable mutlispark simply set Enable Multiple Sparks to true. NOTE: The configuration, Delay Dwell settings should be set with extreme caution as serious perminent damage could be caused to your engine and safety. Configuration Definitions Maximum engine speed(rpm) This is the maximum engine speed that multispark will occur. At engine speeds above this set limit multispark will be disabled. Fire sparks for this angle duration(deg) This is a set angle duration after the first ignition spark that subsequent spark events (multispark) is allowed. If an additional spark is scheduled to fire after this set window then it will not occur. Maximum extra spark count This is the maximum number of additional spark events not including the main spark event. Spark Duration(ms) This is the time the spark occurs during multispark. Dwell(ms) This is the time the Dwell period is set for. Keep in mind that this time does not need to be as long as your main ignition dwell period due to a partial burn having already occured. Not only does it not need to be as long it should not be to prevent overheating of the ignition coils.
