  2. OBD2 question

    in G4+

    Posted

    This is the can1 port I’ll have to use isn’t it?

    So I’ll just use a canpcb cable or make my own with a RS232 connector plugs and wire the obd2 plug as pictured?

  3. OBD2 question

    Posted

    So I’m using a link altezza ecu in my jzx110 But I want to use a link defi Bluetooth smart reader I have to bring up some gauges on a tablet

    i know Toyota have use their own version of obd2 and it’s just the plug that’s similar so the reader isn’t picking anything up  
     

    so is it possible for me to repin the obd2 plug to suit? Or will I have to use the can/rs233 port and wire that to the obd2 plug with CanH and CanL?

     

    cheers

    Yep, that works fine.  I can help you setup the CAN setup when the time comes.  Take a look at the 14point7 Spartan 3 as another decent low cost option.

    Thanks Adam

    which of the 2 would be the better system?

    I think I’m better going with canbus lambda over the analog type?

    can you post the PCLR file you got it running with please? your fuel table seems to have changed quite a lot - the first map showed ~45 in the cell where its idling, but the new log says its using a fuel table value of ~90. If you are still in traditional mode you need to drop the value in the fuel table by quite a lot or you will max out the fuel table under power (max value is 150). Lets say you halve every value in the fuel table, then you need to take on Adam's point above about the master value doubling.

    Traditional mode fuel equation is (simplified) injector ms = master fuel value x map value [100kpa = 1, 50= 0.5, etc], x fuel table number. so at 100kpa with a fuel table value of 100 you would get the same pulse width as master fuel. This also means you can double the master value, halve every cell in the fuel table, and still get exactly the same injector pulses. 

    When I suggested you drop your master fuel, it was because your startup fuel pulse widths were very high, but I suspect you have changed a lot more than just the master value for that new log.

    I’ll upload it when I get a chance cj, I’m away with work and won’t get near the car or laptop to do it.

    Yes it would but i'm not familiar enough with the 2JZ throttle wiring to tell you which value is correct. If you have it wrong/off I think you can only get the TPS to move to 40 or 50%. 

    Set throttle control to "always run" then press the pedal & watch the throttle blade, does it move all the way open and closed?

    It will be a few days before I’m near the car again to check that.

    I’ll let you know as soon as I can.

    I appreciate all your help mate. 

    Cheers

    Ah, looking at your tune again, both the TP & AP sub sensors max out at about 65% and are configured this way in the calibration, so those readings are in fact normal on your car. 

    In traditional fuel tune (which you have configured) you dont specify the injector size directly, just an arbitrary number of milliseconds as a reference point for all other fuel calculations. In your case this is currently 16ms, and should probably be dropped to 8, then adjust as needed as it warms up to get warm idle at correct lambda. Then work on the rest of your fuel table. There is a guide on this in the help files under "first startup" or similar.

    Modelled mode does take into account all the injector parameters, so you need to decide early on which one you will use as the fuel tables are completed different, and a lot of the warmup&compensation tables need different values on a modelled tune

    I’ll change the fuelling to 8ms and see how that goes.

    I’ll recheck the wiring. 
    Would the polarity of the relay for the E Throttle on Aux 2 affect my E Throttle?

    What size injectors are you running and what fuel? Its pushing 17ms of fuel at 3-400 rpm so I suspect its running very rich unless they are very small injectors or methanol.

    There is something still badly wrong with your ethrottle. In the log, TP Main & Sub do not follow each other (sometimes they are both 100%, sometimes TP main is only 70-80% while sub is at 100%). I see the same pattern with your AP main & sub. Can you check that you have mixed up the pin assignments - ie that both sensors on the pedal are wired to AP main & sub - and NOT something like both AP sensors running to the 2x "sub" signals?

    Hi CJ


    Injectors are Denso 570cc and it's just normal pump gas.

    do I have to enter the cc of the injectors into the ecu?

    when the car runs it does run very very rich. 

    I have calibrated the E Throttle serval times. 

    Ive it wired like this 
    Aux4 is throttle control motor-
    Aux9 is throttle control motor+

    Aux2 is throttle control motor clutch -

    TPS main is to AN VOLT 6
    TPS sub is to AN VOLT 5

    APS main is to AN Volt 3
    APS sub is to AN Volt 2

    Do you have realistic RPM showing in the software when cranking (~200RPM)?

    A couple of things to fix:

    1. Trigger offset looks wrong, normally around 200deg on this engine, if you havent already checked with a timing light, set it to 200 and check with timing light.
    2. E-throttle target table is all zeros.  Put something like 4% in the top row and interpolate to 100% in the bottom row as a starting point.
    3. Idle ign table is messed up.  I suggest you just turn this off for now and fix it once you have it running.
    4. IAT sensor is not working.  Fix it or turn it off if it doesnt have one.

    Otherwise the rest of it looks like it is close enough to get it to run.

    If it doesnt run once the above are fixed then do a short log of it cranking and attach it here.

    Hi Adam

    the RPM doesn’t change when cranking, it’s just as shown. Should this move when cranking?

    I thought I had the trigger offset set at 200  but I’ll set it to that and fix the other things and try start it.

    I’ll upload a log if I have no luck 

    thanks

    can you post a log of it trying to start please? Need that to give you the "right" answer.

    Things that might be a problem just from the tune file

    1) you trigger 1 offset is not anywhere near the expected 1jz or 2jz angles, have you checked it with a timing light?

    2) your ethrottle target table is all zero's. its also got a  axis of MAP rather than AP%. It *might* start but it wont run well like this.

    3) your inlet air temp is showing an error value - maybe its wired wrong?

    4) your tp main & tp sub are about 3% apart. have you calibrated this?

    Hi CJ

    yes I had calibrated the E throttle. But I’ll go through it again and fix the other issues you’ve high light and see how it goes.

    will up load the log later if have no joy getting it to start 

     

    thanks

    Hi all

    So basically I've repined my jzx110 to run the link p&p altezza ecu and I'm looking to get the car to start up.

    I tried to get it to run but it wont fire up. I'm sure I've missed a few things when trying to configure the ecu so I've attached the base map that I'm using hoping someone can have a look at it and point me in the right direction where I'm going wrong

     

    Cheers

    I think it would work, you might want to swap to one of the solenoid style ISCV's for the 1J that are available now so you save an additional 3x Aux outputs.  eg: http://www.ebay.com.au/itm/Syltech-Idle-Air-Control-Valve-IAC-1JZ-GTE-for-Haltech-Microtech-Link-Standalone-/201726865037?hash=item2ef7dbae8d:g:4pUAAOSwuzRXcijZ

    thanks for the reply jmp

    I'll have to look into that. It would be handy if it did save me some Aux outputs. I'm just going thru wiring diagrams at the minute to see what exactly I have to swap about. I know the jz runs the injectors in batched sequences. so would I be right in thinking I'll have to repin the link ecu so I'm only using 3 of the 4 injectors out puts on it for the 1jz?

     

    Yes it will work.

    I have done this a couple times.

    Might run out of I/O for the stepper motor iac though.

    Hi Brad

    Thanks for your reply.

    How did you get around the issue of running out of I/O for the stepper motor?

    the engine I will be running is the non vvti 1jz. I would have thought I'll be freeing up some outputs on the link ecu by not running the vvti like I did on the beams engine.

    Hi guys

    So basically I had turbo'd my 3sge altezza and had it mapped on the Link altezza plug-in ecu. I've since decided to fit a 1jz now (currently in the middle of doing this)and I want to know if I can rewire my Altezza G4+ plug-in to run the 1jz?

    Would it be possible to re-pin the jz loom back into the ecu plug on Altezza loom? As I would like to try keep the dash functional.

    Any help would be greatly appreciated guys

    Thanks
