    Ducie54 got a reaction from Brad Burnett in Differential fuel pressure - Nominal fluctuation range?   
    I see just over 5 KPA pressure drop as an example.  I find the pressure slope of the turbosmart 1200 to be very good, that's what I use. 
     
    I would try a better quality fuel pressure regulator and rewire the fuel pump using a realy close to the pump with large gauge wiring.

    Note you can also make your main RPM limit table 3D to add extra parameters.  Fuel pressure protection for instance if you use Differential pressure it should be relatively constant under all conditions so you dont need a full 3D table - you could just put it on one axis of the RPM limit table.

    Check the injector settings tab and make sure there all set the same. Either peak and hold or saturated

    Try this. Load this map.
    Open the trigger calibrate widow. Click set base timing
    Set ignition timing to 15 HIT ENTER, set delay to 40 HIT ENTER. Change offset until harmonic balancer reads 15deg HIT ENTER.
    Leave window open and let water temp to come up, once at normal operating temp set idle screw so idle is just below target. Now hit done on base timing popup.
    This map is using idle ignition table. Let me know how this goes.
    Also any reason why your using MGP as a fuel Axis on a sr20ve? I would look and either MAP or TPS if you have poor map signal. Are you using a wideband to adjust the fuel table?

    Ducie54 got a reaction from krohelm in VE way too high   
    Use cal tables 4,5,6 for linear sensors. Your current settings are already linear and correct but it hard to visually see unless you do an interpolation over the top. Once you have your CTC setup you should also be able to Zero out the warm up enrichment table. I only use IAT correction as extra at idle and high Air temp

    Any reason you have both the charge temp and IAT correction tables active?
    If you have a spare injector I can work out its dead time use the LINK injector test feature.

    I know that this doesn't answer your question, but the greater water flow through a closed loop water 2 air circuit the quicker air ambient air cools the water down. 
     
    Use a 2D PWM table with rpm on the axis. 500rpm @ 75%DC. Set condition 1 only with rpm greater than 500rpm

    Ducie54 got a reaction from TechDave in Cant reach boost target   
    Start by getting a nice flat boost cure @ 274Kpa then add axis above and below. Subtract DC% from 274 figure when boost is more and add DC % from 274Kpa when boost is less. 280 row is left at 0 as a safety, so if boost spikes it comes down quickly. Use the log file to help with DC figures. 
    High performance academy have some really helpful videos on this subject and many more.

    If your using the the FP speed table make sure you use all 14 Cells even if you don't need them. As advised by Simon. Works well after that.

    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...
