    Adturb reacted to Adamw in Evo 9 Intake Camshaft Position Sensor Error! Help!   
    The cam position would be able to go to "-10" instead of stopping at zero, the ecu will report errors and disable cam control if it goes more than a couple of degrees below zero.

    I honestly noticed this recently with my gear display on my dash, I chocked it up to me playing with rear gear ratio at first but after a re-calibration of the wheel speeds its still kind of spotty and inconsistent.
    Maybe @Simon or @Adamw might have some insight on this.
    As for + to X platform upgrade, the physical pinouts of the units are not changing.  Its just a new processor in the box with new software, firmware, and functionality.  The physical I/O is not changing.

    The engine capacity setting will mostly just scale the airflow calculation up or down.  So if you get it wrong your VE numbers wont quite match reality.  Probably not a big deal.

    You are correct, on the Evo9 plug-in the tacho is driven direct from a circuit that gets its signal from the crank trigger.  This was done to save an aux output as the evo is particularly hungry for aux outputs.
    You will be able to make Inj 7 drive the tacho but there are a couple of gotcha's...  Inj 7 is connected via an internal circuit to DI7 & Ign 8 so you wont be able to use these for anything else - they will have to be set to off.  Inj 7 doesnt have a pull-up resistor fitted like most auxes do so you will need to add your own pull up resistor to +12V.  I suggest a 2.2Kohm.  Pin 59 is a switched 12V so that is convenient.  Something like this:

    Adturb reacted to mapper in Questions about the capabilities of a WRX9+ G4+   
    Guys relax a bit. 
    I've mapped and I'm supporting several 600-800hp 2.0 to 2.3l time attack engines/cars with a Link ECU and multimap strategy.  Such an engine runs usually for 5000 race track kilometers until a rebuilt is needed. That's a similar distance to a 24h race.  I like to answer your question.: 
    All LINK ECU use the same PC-Software and the same Firmware. The main difference between all LINK G4+ ECU's is only the hardware.
    your tuner should tune the main Fuel and ign Maps from the lowest to the highest boost levels. There are 3 main Boost Maps in the LINK ECU. You can additionally span one of the axis of the Boost Wastegate or Target table to a driver Rotary Switch. So it's possible to have up to 33 different boost maps, which all can be switched on the fly. 
    On top of that, you can activate 4D fuel and ignition tables on one or several of the boost maps. This allows trimming Ignition and Fuel on some maps if you or your tuner like to do that. 
    The Link Ecu is really flexible. Usually, the only limit what you can do is the creativity of the tuner. 
    As an example, we installed 3 rotary switches in a Time Attack/ Hillclimb car.  One 12-Position Rotary Switch is used to choose between 12 different torque maps (mainly altered by boost strategy). The Launch RPM can be chosen over another 12-Position Switch, depending on whether and Track conditions. And lastly, we have a 3-Position Rotary Switch to choose one of 3 Drive by wire Throttle Maps.  
    For engine Safety, we set up Limits for too low and to high Coolant temp, Oil temp, Oil press and Fuel press. We are also using full time closed loop lambda and sending a lot of Data over a custom CAN. 
    As you see, the LINK is a very capable system.  But as every ECU, it needs a capable tuner to use it properly.

    Correct, it should have a stock solenoid in that car, usually you would just connect the new solenoid to the wires for the original valve.
     
    Wrong.  One side goes to a switched +12V source.  The other goes to an aux output.  There are no aux outputs available on the expansion connector on that ECU, so you should connect it to aux 1/Pin 105.

    Hi, to use the Link software as Dash in the next update you could remove the outer frames of the watches and always be in front.
    This way it could be configured similar to a Motec or other Dashboards
    The Dial gauge RPM could also be improved with a more "Racing" look
    I attach an example

    Adturb reacted to Adamw in Crank trigger tooth count   
    I assume we are talking Evo 9 Mivec?  If so the mivec cam position is done by a separate sensor to the trigger “sync” so you are free to change the trigger.  Note you will need to remove one tooth from the exhaust cam if you are changing to a generic multi tooth or missing tooth crank.  
    Benefits of a higher tooth count is more correct/stable ignition timing during fast transient conditions so if retuned you can often run more timing before the knock limit is reached.

    Adturb reacted to Scott in Idle control G4+ & G4   
    Hi Tony,
    You recorded that log file well.
    I can see by looking in it that the Idle Status says 'RPM Lockout'. This is because the engine speed is more than 500 rpm above your target. It means the idle control is not trying to control the idle. In the log your idle position is between 70 and 71%, yet the base position table is asking for approximately 44%. I would say the ECU is adding the 25.5% from your Park/Neutral step as your Park/Neutral Status is off, so the ECU assumes you are in gear. You don't have a park/neutral switch to the ECU, so I recommend setting the Park/Neutral idle step to 0.0. This will then lower the idle position significantly and hopefully allow the closed loop control to achieve the idle target.
    Scott.

    Adturb got a reaction from Rampant in Closed loop Lambda (AFR)   
    Couple of plans of attack here- I scale mine inversely (0v = lean/ 22AFR, 5V = rich/ 8AFR) so if the MXTL dies then it'll overfuel rather than run lean. The ECU can be set to work on a narrow range, as most sensors do- 0.5 to 4.5V, either side of that (0 or 5V) will register as a sensor fault- I tried this but kept getting false ECU alarms, I don't think there is a time delay on the alarm so it activated each time the car started. Thirdly when you set up closed loop it is only active under certain conditions, typically cruising/ steady throttle. Furthermore there is trim limit, so it can't or subtract more fuel than that setting- I think I set mine to 8%.

    Adturb reacted to TnF in REQUEST/IDEA - Control multiple features via a single Analog input (or DI, CAN, Serial etc.)   
    Hello. This is something i've been thinking long ago, even before i bought my Link G4+ xtreme black ecu. I am not sure if you will flip me off because it will probably be much work for you guys but on the other hand i believe no-one has such a feature and it goes more into OEM one-off applications we see in newer cars. 
    So to get going, my idea is a feature where in the simplest form is to use a single Analog Input to control multiple parameters (in the activate-deactivate sense) like launch control, anti-lag, traction control, map switching etc so to spare DI for other stuff. Normally if you want to have control over these features/parameter you require to add switches wired to DI's for every one of these things you want to control. However assuming your analog inputs have 10bit ADC's it gives 2^10=1024 individual voltage steps from a range of 0-5V (5/1024=0.0048V per step) which gives 10 possible combinations of parameters you can control (ideally, in reality the ADC might be too sensitive so we go down to less parameters (5 parameters for a 0.02V voltage step). So from Link's side you essentially need to construct a "table" where you can set 10 different parameters to control on and off. To simplify this let's go down to 3 parameters to make this easy to visualize:
    where x means the function is activated and blank means it is deactivated .
    Of course it doesn't have to to be a table with voltages like that since if using 10 parameters will require 1024 columns for the voltage steps. The proper way to do this is via binary counting since you can easily index all combinations and calculate the state of each parameter (on or off) without an array which would take lots of space. As a follow up to the example above where we set n=3 as the total number of the parameters to control we need a binary value of n (3 in this case) digits. If we set 1st digit as parameter A, 2nd as B, and 3rd as C we have the following combinations that will always hold true (index the same) for any n number of parameters we want to control:
     Thus we can easily calculate and control any parameter directly through the ADC value of the analog input. This works great for both sides (Link ecu and client side of which i will go into detail later in the post). To simplify again how this should work lets break it down. In this case let's say we use all 10bits of the ADC.
    PcLink should have a table that you can set 10 parameters to control. It is important that these parameters are entered with the same order for both PcLink and client side. Let say we set:
     Let's say i want to activate B and H. This means i need to convert the binary 0100000100 (note where i put 1's, B is 2nd, H is 8th). If i do the conversion i end up with the decimal value of 260. Then the client side DAC sends a signal of about 5V * 260 /1024 = 1.27V. The link ecu receives this voltage on the analog input (ADC) and measures it as decimal 260. Converting back this decimal to binary we get 0100000100. The ecu sees the 2nd and 8th digits of the binary value are 1 so it activates functions B and H. I hope this makes it clear. We can go into more detail why this not work perfectly and the ADC might read 259 or 261, thus why i said we might need to use less than 10 parameters depending on the sensitivity of the ADC. Also you are not limited to using a single ADC. If you have 2 analog inputs connected you can potentially control 10x10 = 100 parameters.
    Of course we are not limited to using analog inputs for this feature, we can do this via a DIGITAL INPUT, SERIAL, CAN etc. Client wise this is very easy to do. What i personally plan to do is use a microcontroller (an arduino for example), an oled screen and some push switches to make a nice, user friendly interface where you can select what to control at any moment without having to add lots of switches and knobs. I am also planning to control more things, like boost target since a $5 arduino microcontroller gives you lots of I/O. Plus it only costs $10-$20 in materials total. I will freely provide code, schematics and diagrams if this thing is implemented. It's not that i can't at the moment, it's just i will run out of AN's and DI's which should be reserved for sensors, not for controlling FEATURES. 
    SO PLEASE PLEASE PLEASE MAKE THIS HAPPEN! NO OTHER AFTERMARKET EMU (i know of) has such a feature and would add greatly to your products. And while you could release such a module yourself's please do not make it proprietary, we want to have the flexibility as end users (afterall that's why we bought an aftermarket ecu in the first place!)
    AFTERTHOUGHT: I bought an aftermarket ecu not to make more power - you only require air, fuel and right timing for that - but to get and control more features. This is so that i can modernize the car and make it more relevant as a daily and even give more flexibility for a motorsport application. All the above and more can be done really easily nowadays - you can get a cheap windows tablet connect it via usb and run PcLink on it if you want. And this is another way we should think my idea. Maybe you want to use it as to monitor stuff without a laptop, control things, think of R35 dash for example. Why bother to use OBD when you can do so much more via direct USB? It is not like hardware changes are needed, you can do this via software alone. So please consider this
