    pasta got a reaction from Vaughan in DBW Engine fan step not work   
    I overlooked fan 2.
    Thank you for your prompt reply

    Engine fan 2 is always on in that log so maybe make engine fan 2 & 3 temperature settings the same or higher than engine fan 1.

    I've tuned a few hundred 3sgte mr2s, and been specializing in them for 20+ years.

    pasta reacted to Confused in GP PWM - Econo/Boost gauge setup help.   
    Now that you know it works kind of as expected and the output is driving the gauge, you can start to fiddle with the output value, and make a note of what duty cycle gives you the desired result on the gauge.
    So, I would set up a basic table with no axis values (press X):

    And then just modify this single-cell table, and watch the gauge. Make it sit at a few different points, say 10, 20, 30.

     
    Then, once you've written down your values, you set up your table appropriately, such as:

    (Note, my configuration here is set up for metric, if you want your boost in PSI, modify the values accordingly if you're not already set into PSI mode)

    pasta reacted to Davidv in Injector Timing   
    Remember that injector timing only really makes a difference when the injector is open for a very small amount of time. Such as idle or cruising. 

    Because once you're up to say 70% or higher duty cycle, your injector is firing for so long that it makes little difference.

    I've found that around 400deg is good but on cold starts bringing closer to 250deg (from memory ) meant I could reduce cold start enrichments.

    I wanted to share my success using a bluetooth adapter since I have not seen any other posts about using one on this forum. So far I have only tested it with an Android tablet and RealDash. It has been working perfectly. Connection is fast and very reliable. There is no noticeable lag on the dash interface. 
     
    There are a few advantages of using Bluetooth over USB for a tablet dash.
    1) The usb port on the tablet is freed up to be used for charging (this can also be used to automatically turn the tablet on/off with key power)
    2) The usb port on the ECU can be dedicated to the Laptop usb cable for tuning (dash cannot be used simultaneously with laptop, but less plugging/unplugging)
     
    This is assuming that your Link ECU has separate tuning and CANBUS ports.
    The Bluetooth Adapter I have been using is one made for Megasquirt MS2/MS3 – PerfectTuning is the manufacturer. https://perfecttuning.net/en/accessories/26-bluetooth-adapter-for-ms2-and-ms3.html
    There are a few other BT adapters for megasquirt, they are all likely the same Bluetooth chip and work the same. The Megasquirt uses a DB9 connector for serial connection, so that is what comes with the BT adapter. In order to connect to the Link you will need a Link CAN connector http://dealers.linkecu.com/CANF_2 These connectors need to be soldered and can be somewhat difficult due to their small size. Cable pigtail is also available but fairly expensive.
    The following is the pinout on CAN connector, the BT DB9 connector and where those wires need to end up. This can be wired a few different ways. Either the DB9 connector on the BT adapter can be mated to with a female DB9, or it can be cut off and hardwired (or use a different style connector). The two serial wires will go to the CAN connector on the ECU (TX to RX, and vice versa). The 5v and GND wires will need to go to a 5v power source. Do not use the 5v supply from the ECU, the BT adapter can draw up to 30mA. 12V DC to 5V power supplies are very common, it is the same voltage as USB chargers. What I did was buy a USB charger and hardwire a USB cable pigtail to make the connection. I used and like this model:



    I recommend powering the 5v power supply from the ACC terminal (radio power) on the ignition switch. This way there is still power to the Bluetooth with the key in position 1 (ignition off). This will allow you to power cycle the ECU without killing power to the Bluetooth adapter – leaving it wirelessly connected to the tablet. This means that the dash will be live in about a second instead of 5-10sec.
     
    In order to use the tuning port to connect a laptop, either the CAN connector must be removed or a 2 pole switch/relay must be put on the serial wires coming from the CAN connector. The switch must be within about 20cm of the ECU, otherwise the serial stream may become active and not allow the laptop to connect. Once the laptop has been connected, the ECU must be restarted to allow the serial stream to become active again. Hopefully in the future this can be changed by Link so that the serial stream is reactivated upon laptop disconnect.
    If there is interest and the forum allows, I could possibly make and sell a plug-and-play Bluetooth solution for the Link G4+. Cost would likely be just a little more than the Perfect Tuning adapter.
    Here is a video of my dash on a “cold start” – Powered up and connected in less than 10 seconds. Realdash can be set to allow the tablet to sleep when charge power is killed from the tablet. It works well as a OEM style dash and I don’t need to manually touch the tablet at all.
     
    This is what the inside of the PT BT adapter looks like. 
    Blue = 5v
    Orange = GND
    Grey = RX
    Yellow = TX
