    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 .

    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 .

    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

    Semi sequential fuel with distributor

    Just to give you another option with your injector pairing - As opposed to the link instructions . With the distributor its easy to get the semi sequential as good as it can be . IE every second injector of the pair is only 90degrees out . So the way i did it ( remember not technically as per the manual) Is wire the injectors - Injector 1 - 1&8 . Injector 2 - 4&3 . Injector 3 - 6&5 . Injector 4 - 7&2 . Then input the firing order 15263748 . The ecu will then evenly space the injection events . Just wire the HT leads on the dizzy as normal . It just made sense to me to not leave fuel puddling in the port any longer than need be .

    Hi- Did you get this sorted ?

    Logging fuel map .

    Cool - Thanks Dave

    Logging fuel map .

    Hi- Is there a way with logging to bring up the whole fuel map and scroll along a time bar to see which cells were accessed over the time period logged ?

    Polishing the tune

    Thanks Clint. Thats a plan . Are there any parameters or compensations that you log to help with this process or if i log the basics is it fairly straight forward to see where i need to make changes ?

    Polishing the tune

    Ok - i want to be able to set up mixture map to correct the fuel map the same way CLL does . So at the moment with CLL active as i drive it continually corrects based on my AFR target - . Is there a way i can turn off CLL and set up mixture map to apply the same correction strategy ? Hope this is clearer ? Its just ive been unsuccessful with using mixture map as i dont know how to set it up with out it making my fuel map worse - But CLL seems to correct pretty much the right amount as i drive .
