    Adamw reacted to Richard Hill in ECUMaster CAN Lambda working ?   
    Here is one i put together.  It was done a few months ago with a pre-production unit, so might need to check that nothing has changed.
    HTH,

    Sorry, I don’t normally use that pic host but sometimes have to when my normal one is not available.  I’m overseas for a couple of weeks but should still have that pic at home or I can do the test again and redraw something.  Give me a reminder in about 10 days.

    Adamw got a reaction from tiago in Not able to connect to Link G4+ after a bad wiring - Is it dead?   
    As CJ says it is most likely a wiring problem based on the dash lights.  Quickest way to confirm the ecu is ok is to remove it from the car and power it up on the bench with a couple of test leads.  Easiest way to power it up is to find the big barrel shaped tvs diode near the main header, clip +12v to the leg on the striped end and clip ground onto the other end.  You will see the led light come on if all ok.
    The marks on the mosfets in your picture are just air bubbles or runs in the conformal coating.

    Adamw got a reaction from Focos wrc in Trigger scope issue   
    Ok, trigger 2 voltage is quite low so set trigger 2 arming threshold to 0.2v @ 0rpm and 0.5v @ 1000rpm.  
    It would be strongly suggested to remove one tooth from the dizzy for the most robust triggering but it may run with the duratec mode.  You will need to check trigger offset with a timing light.

    There is no easy way to create the transient timer filter that I can think of at present since tp delta is not available for use as a virtual aux condition.  The only work around I can think of that I’ve used in the past for odd tricks is if you have an ecu with 2 CAN ports you can connect them together, send tp delta out of can 1 and receive it into can 2 as a CAN AN V then use that for your virtual aux.

    Typically done as a downshift blip.  You will find this function in Gear shift control, overrun downshift throttle trim.  Note it is not "rev matching", the purpose of the blip is to unload the dogs to allow it to change out of gear.  It is typically trail and error, how much you need depends on a lot of factors such as the the size of the plenium, the mass of the rotating components, throttle size and how much back cut the dogs have.

    Adamw got a reaction from Knox in Mild ALS without air bypass   
    You will get different override settings depending on if your idle valve aux outputs are set up for stepper motor or solenoid valve.  In the case of an evo with a stepper motor the ISC override setting will be the number of steps from full open, so the smaller the number the more air flows (just like the idle base position table).  Note the minimum clamp setting in ISC settings is always active so you may need to set this lower also.

    Adamw got a reaction from Ducie54 in Weird firing order   
    Although it will run ok with the incorrect wiring, there are two significant negatives in my view:
    Because you have had to set the wrong firing order in the software but the injectors are wired "correctly" from the factory, it means your injectors are now firing in a different firing order to your coils so you have lost any performance advantage of sequential injection. It leaves the potential for someone to make a mistake in the future, especially if you want to do individual cylinder trims, knock control and also scenarios like testing injectors/coils when diagnosing problems is going to be difficult to interpret.  It should take less than 10 minutes to swap the 3 pins at the ECU connector so I would strongly suggest you save yourself a potential f*ckup and correct the wiring.

    For the ODO function you have no speed input set, try it as below:

     
    For the fuel level, you can try adding some filtering as below, unfortunately it only lets you average over a maximum of 5 seconds which Im not sure will be enough but give it a try.  Otherwise you will have to add a resistor/capacitor to the fuel level sensor wire.

    Adamw got a reaction from Simon in Arctic cat Power valves   
    Im not sure if they do a reset/calibration on power up or not sorry, I have very little info about how this function works.  The best I could suggest is set the power valve control settings to some very low RPM when the engine is idling and see what happens.

    Adamw got a reaction from mapper in launch control dbw limit   
    Could you not use 2 axis on one throttle table to do both different antilag settings, to free up a table for the launch?
    For instance example below.  Table 1 = normal touring.  Table 2 = 2 different antilag bypass amounts.  Table 3 = wheel speed based launch throttle reduction.

    Hmm, good catch.  It does actually work and display correct on a live ecu but they are going to have to fix that.

    Adamw got a reaction from Fotis in Link Monsoon   
    The crankshaft turns twice per 4 stroke engine cycle.  So the missing teeth on the crankshaft wheel can only tell the ECU where TDC is, it cant tell the ecu whether it is TDC for cyl 1 or TDC cyl 4.  Only a cam sensor can do that.
    So if the ECU doesn't know if it is TDC 1 or TDC 4 then it cant fire the correct coil or the correct injector in seq/direct modes. 
    Injectors don't need to be re-wired - just change the setting to multipoint group.  Coils will need to be rewired to the correct drives and ignition mode set to wasted spark.
    If you want sequential or direct spark you need a cam sensor.

    Adamw got a reaction from JonoP in Cold Start - Pre Crank Prime and Crank Enrichment Tables   
    I think with engine temps of 10°C and 94% ethanol you are going to struggle with cold start and there will be little you can do from a tune perspective to help.  The vapour pressure of straight ethanol is very low so there will barely be any vapor in the port at that temp no matter how much fuel you dump in, it will just remain as liquid. Somewhere below around 10°C there is not enough vapor produced to support combustion.  This is the reason why pump E85 gets reduced to E60-E70 in winter so there is a little more of the volitile solvents available to create some vapor in the port.
    In regions like Brazil etc where they predominantly use straight ethanol it is common to use heated injectors to get around the problem.

    Adamw got a reaction from Stillrolla in Multi fuel - E85 Leaning out   
    I would say your MAP sensor is dying.  When it starts to go lean the MAP is only reading 6KPa which is near impossible (it shows 0 in some areas) and at the end after it stalls the MAP is 74 when the BAP is 92.  MAP and BAP should read the same when engine is off.

    Adamw got a reaction from Simon in Wire type and sizes   
    The Link looms use a Japanese standard thin wall automotive wire known as "AVSS".  It has a higher temp rating (120°C) than common PVC insulated wire.
    Most of the wires are 0.56mm2 from memory except for the two main grounds and the main red 14V wire, these are 0.75 or 0.85mm2 (sorry I cant find my old spec sheet).  
    If you are in USA, a very similar alternative would be 20AWG TXL for the small ones and 18AWG TXL for the power/gnds.

    Ok, all the CAN is done, I havent added any of the new channels to displays or whatever but they should now be available.  I have kept all the channel names pretty much as per the BPM datasheet.
    The only one that is a bit ambiguous is Fuel level.  He has used 2 bytes like it is expected to cover a large range of numbers but then says the range is only 0-53L.  Just one byte can do up to 255 and 2 Bytes is capable of 65000.  So I suspect he might be sending it as "0.1L" rather than whole Litres but that is not clear. If your fuel level says "500 Litres" when you have it all working then set the scalar to 0.1.

    I can help you with the CAN set up if you first confirm what device you have.  The document you attached is for a device from a company called BPM auto electronics.  It is not a Motec device.
