    ISC solenoid

    Hi Adam - I dont seem to have that option on my idle control page . No park/neutral step . Is it on the Atom G4+ ? . I have not up dated the firmware in a while although it is mentioned in the link help file . I doubled checked my settings on the anti stall gain and i have increased those - From 15 to 25 . So ill try that too .

    ISC solenoid

    Ok ta for that . Also is there any way to speed up its action . Even with all gains maxed it is painfully slow to open and react when say putting the car into gear ( Auto ) . You can watch it count open in tenths of a percent on the lap top . How fast do the Bosch solenoids react ? Is it the valve thats slow ? Or just the way the Link controls it ( Its set to 200HZ ) Are there faster reacting ones on the market that the Link can control faster ?

    ISC solenoid

    Hi- with the Atom G4+ - When the ecu powers up but the engine is not cranking or running the isc solenoid ( bosch 3 wire ) stays closed . Is this right ? It only starts to open when cranking . Can i get it to open to its set point in the - idle base position table - before closed loop control takes effect ??

    Lean warm/hot restart

    Hi- My engine suffers badly from heat soak and i have done the same as cj suggested and have managed to get the problem sorted to the point where im happy with it .

    4L60e

    Hi- Thanks for the reply - I see in the 4L80 post your question about TP sensor being used to control line pressure - Hope this works out . Please keep us informed with how youre going with the project - My only alternative is to buy a stand alone controller for about $500US . Plus frieght plus gst . Itll work out about $1000 bucks !!!! .

    4L60e

    Hi- Are any of the G4+ range capable of controlling the GM 4L60e trans as well as the engine { not a chev } . Or does anyone know if i can use the LT1 computer to work the trans and the Link will run the motor ?

    Menu of options

    What about having the ability to ask for additional ecu features off a "Menu" with a list of costs . For example i have a G4+ atom but would love - CLL wide band mode auto - . As an added feature . Or add more injector drives etc etc . Pay for the base ecu plus additional costs for additional features . Possible .?

    Y34 Gloria VQ30DET Thunder parallel install issues

    Some old school cars supply different components from the ignition between the " start" position and the "run " position - i wonder if this is at least part of your problem ?? Maybe coils not receiving power on crank ?? Just a thought .

    Problem setting base timing

    Hi - I had a similar problem with trying to set the base timing on my engine when initially setting it up . Timing would not hold and advance uncontrolled when reving the engine - Turned out to be " spark edge " was set wrong in my case . I had it set to " falling " and needed "rising " . Not saying yours needs to be rising but you could swap what you have entered and try it .

    idle issues,2004 ej257

    So im far from being a tuner having only done my own car . But on those logs there is no iat compensation being applied that i can see . You should imo look up HP Academy - see what they have got with regard to learning how to tune . At least you can learn the basics through the courses they offer . But yeah the Charge temp approximation could be your issue . HP academy do a webinar on tuning this function . Or you can carefully go through it yourself by trial and error with logging results . This assumes of course that your main fuel table is correct to start with . And all other things such as what Adam said with your idle control function correctly .

    idle issues,2004 ej257

    Sorry . My bad - i added it to the parameter list that came up and it showed it so all good now . Yeah it shows it lean at readings up to 1.3 lambda .

    idle issues,2004 ej257

    So on those logs is lambda recorded ? I cant see it - am i missing something ? I dont see it on the parameter list or the time plot ? In any case the IATs are in the 80s from the start and even after a minute of running dont cool down much . Sorry if i missed the lambda reading but it still could be heat soak imo .

    idle issues,2004 ej257

    Could the intake manifold and IATs be hot after heat soak leaning out the mixture ? Then when you start it and fast idle for a few mins it normalizes? Just a thought - This can be easily compensated for if you find thats the problem.

    0-5v output for MAF simulation

    Forgive me if im not following but cant you just use a map sensor - feed it 5volts and use the output voltage ?

    Semi sequential fuel with distributor

    Chris - The pairing follows the correct firing order 18436572 . The injector drive 1 is wired to cylinders 1&8 . Drive number 2 is wired to 4&3 . And so on . If you enter the firing order i suggested injector drive 1 will fire first - injecting fuel in ports 1&8 . Cylinder 1 receives the fuel at the correct time - cylinder 8 gets its fuel 90 crank degrees early . The ecu ignores the number 5 in the weird firing order and moves on to drive number 2 . Which injects fuel for cylinder 4 at the correct time and cylinder 3 - 90 crank degrees early . And on it goes . With the input firing order of 15263748 the ecu ( Atom G4+ ) only sees the 1234 and because theyre evenly spaced you get well timed semi sequential . The distributor leads still are wired and go to the plugs in the true order 18436572 . As it receives 8 signals to fire per 720 degrees it " distributes " the sparks to the correct plugs . Ive read this a couple of times so i hope it makes sense to you
