    Ducie54 reacted to cods4 in Rough Idling During Cold Start - Trigger Related   
    Well I was going to email this to Link Support but I cant find an email address so here it is.
    Can anyone help me?
     
    Subaru Impreza STI V4 with Link G4 Plug-In ECU


     
    Vehicle Details

    1998 Subaru Impreza WRX STI V4

    ECU: Link G4 Plugin for V3-4 STI

    Engine: EJ20K with 3.5Bar Map, Bosch IAT sensor, top mount intercooler

    Fuel: E85 fuel, ID1000 Injectors running stock fuel pressure

    Turbo: TD05-18G

    Problem description

    Car is very hard to start and when it does eventually start it runs very rough for a few minutes. It eventually runs correctly and then has no further problems until it is started next time. The rough running lasts the longest when the car is cold.

    While the car is running rough the rev counter is jumping up and down and generally giving erroneous values. This can be seen in the logging data.

    Background

    Car ran fine with the Link G4 for a number of years. It was converted to run on E85 with larger injectors etc and then ran fine for a few weeks after being tuned at E&H Motors. The starting problem seemed to occur out of the blue.

    Findings

    ·       The ignition circuit and fuel circuits seem to be working correctly. The problem seems to be coming from the ECU.

    ·       While the car is running rough the ignition angle is constantly changing darastically. It sometimes reaches the ignition advance limit.

    ·       While running rough the indicated revs are occasionally reaching extremely high values and causing the rev limiter to activate.

    ·       While running rough the Trig1 Err counter sometimes counts but only small values up to 30-40.

    ·       The problem seems to be related to the Trigger 2 input.

    ·       The Trigger 2 Arming voltage indicates a constant voltage of 0.17V while the car is running rough. As soon as this increases to 1.8-3.2V the car begins to idle/run correctly.

    ·       Sometimes a Hardware Block 3 Error occurs while the car is running rough and this will often correct itself after the car is running normally for a while.

    Questions

    ·       What is the Trigger 2 Arming Voltage and what could cause this to misbehave?

    ·       What is the Hardware Block 3 error status indicating and what could cause this? What does Hardware Block 3 do?

    ·       If the Trigger 2 Arming Voltage is incorrect how come the Trig1 Err counter is not reaching much higher values? I understand this is comparing signals from Trigger 1 and Trigger 2.


     
    Attached Log File

    Please review the attached log file. This is logging two cycles where the engine starts up and idles very roughly for a while before returning to a normal idle and then I turn it off and start again.

    Note the rough idle between 4s and 16s and then the idle smooths out and returns to normal. This perfectly aligns with the Trigger 2 Arming Voltage being 0.17V. The same rough idle happens between 44s and 68s. Also note the Hardware Block 3 Error occurring at 54s.

    It is this kind of this which is REALLY frustrating. "Unlikely to see any future improvements in the G4+ platform"
    The G4+ Thunder I have is barely 18 months old and you guys are already moving on? I have been bug fixing for my entire ownership and feel this is a complete jip.
    I would like a serious and honest comment on this as if this is the case mine is being sold and I will move to another platform that has some life expectancy.

    Hi Dave can you please have a look at the FP speed DC% during logging. Not sure if its normal but when you change the multiplier in the fuel pump control tab the FP speed DC% during logging does not match the duty cycle in the FP speed table. Im using a NZEFI hardware PWM fuel Controller and they are the settings with the instructions.

    Strange how the log shows you get 99% TP main then drops off to 95% Your also getting a TP/Targ Error Accumulator error between 99% and 95% unsure why tho.   
    Also the throttle motor DC% are all over the shop.

    My method would not take into account the multiplier or the clamp, but I would have thought since these are very simple math you could do that on the fly in your head or at worst with pen and paper? 
     
     
    The only way I can think to keep the fuel pump running in normal mode (like the engine is running) is to make a fake trigger.  One method - You could temporarily set trigger mode to "multitooth", jumper a PWM aux out to trig 1. Set trigger 2 mode to none.  Set aux out to test PWM.  ECU should then see RPM...

    I would be asking Simon as to why there soldered and not crimped. Crimping tools are not that expensive, the cheap ones worked will on my harnesses.
    I can't understand why the power wire has the shield attached to the pin. If it's grounded in the CAN lambda module that will give you issues. 
    I'll be pulling my LINK knock block apart to see if it's soldered now.

    Tunning without a knock device is crazy. There not that expensive. If you post your map and a log file I'm sure someone will be able to help you. 
    Remote tuning maybe another option.

    Hi Grant,
    In case my user name didn't give it away, I'm Andre from HPA
    We went down the path of online training because it allows us to help more people all around the world, and we firmly believe that it offers significant advantages to in-person training. It's a cost effective option since you don't need to travel, and you also have the advantage of being able to re-watch our courses as many times as you like. This means you can brush up on concepts that you're not clear on, or revisit concepts that you've perhaps forgotten since initially taking the course.
    The key to our courses though is our support community which is where we bridge the gap between online and in-person training - We believe strongly in supporting our members and this is where our private online forum and our regular weekly webinars help back up the course material. The forum is the perfect place to get fast and reliable answers to your questions, while our weekly webinars are the fastest way to expand your tuning knowledge on a range of engines and platforms, as well as staying up to date with the latest technologies.
    I couldn't agree more with Ben's comment about the requirement at some point to transition into hands-on experience and that's exactly why we developed our 'remote practice dyno' where you can get real world hands-on experience tuning a real engine on a real engine dyno without leaving your house. The online practice dyno is currently operating a Link G4+ Fury ECU which may be helpful to you given you're on this forum. You can find out more about the online practice dyno here:
    We understand that buying online education can be tricky and we want our members to be able to purchase with confidence which is why we also offer a 60 day, 100% money back guarantee - If for any reason you feel our courses aren't right for you, we will refund the full purchase price.
    If you're interested in getting a taste of what HPA is all about then I'd suggest you start by signing up for our free six-part series of lessons. This will give you some insight into how we work and what we can offer: https://www.hpacademy.com/free-tuning-lessons
    In the perfect world I believe the best solution is to get as much training as possible - Both in person and online. I found that when I was operating my own performance workshop however, that unless the in-person training was local, the cost of training staff in this way was usually prohibitive.
    I'm happy to answer any questions you may have

    Last night we released a new PCLink and Firmware, I updated this thread but it didn't stick (weird eh?)
    Thanks for your patience with the 5.6.2 to 5.6.5 update-requiring-ECU unlock bug. Thanks Davidv for his work around.

    We completed our first evo 8 pnp here at the shop on a car we built. Its a 2.0L 4g63 with oliver rods and wiseco HD pistons mated to our head with GSC s3 cams. T4 TS S364.5 SXE turbo with FIC 2150cc injectors and a Walbro 450 pump. We ran about 33psi to achieve the numbers. The ecu is awesome. Setup knock control, oil pressure safety, coolant temp safety(which already saved the car! The new fan took a crap on him when he was out for a cruise and hit the 225* 500rpm rev limit!!!).

    Mine had low voltage like this when the ecu hold feature was not setup correctly in the software. You will find that the main realy will not close causing the voltage drop. You will get voltage both side from back feed but you need to confirm the relay closes

    Ducie54 reacted to Adamw in ross trigger kit rb26   
    Iecku, I just thought I would mention a little bit of info that many people miss.  These kits appear to use the Honeywell 1GT101 sensor, these sensors are much slower on the rising edge than the falling edge.  The datasheet quotes a 15µs rise time Vs 1µs for fall time.  So for at least trigger 1 (that controls the timing) it would be more correct to set the trigger edge to falling. Even though 15µs is only like 0.9 deg at 10000RPM, if you can get extra accuracy just by a simple setting change - then you might as well use it...

    Ducie54 reacted to Scott in Display Link over CAN   
    Hi Nigel,
    To be honest I don't think the engineering team will modify the DisplayLink firmware as it is now some years old. 
    Another solution (that I've already done most the work for) is to make the 'Generic Dash' stream file adjustable by users. A month or so ago I did this for one of our dealers, but have not heard back yet if I created the file correctly.
    Here is an instructional video I made. You can follow this, and go to frame 7 and change the divider for Lambda 1 and Lambda 2 to '10'.
    https://vdoubleyou-scott.tinytake.com/sf/MTA0MzIzNV80MjM4MTcw

    Attached is the file you will need.
    I would appreciate it if you can let me know if this works. If it doesn't I can try and make some changes.

    The solid state relays work fine when wired up using the last wiring pic. I didn't end up using the voltage divider as I run out of voltage inputs. Worked fine when I connected it to the battery. When I'm on days off again I'll test it using PWM and post a log file.
