    injection timing questions

    hi again folks, two questions regarding injector timing maps if anyone can teach me something id be grateful; first question would be what would be a good axis for this map? I'm thinking engine speed for one, and mgp for the other? second question is does injection timing have a big impact on fuel consumption? playing around at idle I found I can reduce my fuel table numbers for the same afr so I guess it would do, just not sure to what extent sorry if its basic stuff I'm still finding my feet a little bit with all the things this ecu can do, any replies always appreciated, cheers, Rich

    g4+ fuel pump control (fixed! see last post)

    Cool, thought it looked funky. Thanks for the reply Adam, seems a simple enough fix

    g4+ fuel pump control (fixed! see last post)

    ah ok not just me then, any idea if it was Scooby related or just the g4+? ill have a trawl see if I can dig it up, found a fella with a evo 5 with some kind of pump issue but his was actually leaning out up top

    g4+ fuel pump control (fixed! see last post)

    just for curiosity I had a play with the settings at idle, mainly by setting a really low medium speed injector duty cycle, and it seems when I request the low pump speed I end up with medium, and vice versa. is this a thing to solve or am I just distracting myself logging too much stuff? little log attached hopefully showing what I'm talking about. thanks peeps fuel pump log.llg
  5. Hello again, quick question for some people more experienced than me, hope its not been covered too many times or a silly question but here goes; ive been slowly getting a tune worked out on my wrx v9 with a g4+, and the fuel pump speeds look odd to me. little snapshot of what happens if I build a little boost with a steady throttle all the way through, it seems like duty cycle would increase with fuel demand, but I may be completely wrong. any help would be great, thanks! (added my actual map to the post,incase it helps) 57.pclr

    knock sensor setup

    thanks buddy, that's what I was using anyways good to know its correct

    knock sensor setup

    can anyone help me out with this, I'm using an ej255 Subaru motor, standard bore and internals, and a bosch wideband knock sensor,and this is on a g4+ ecu. should I be using the 6khz narrowband freq. channel, like the oem sensor, or the 4-10khz wideband sensor option, because of the bosch sensor? I have read the help file and searched around but I'm still abit unsure, any advice would be greatly appreciated as I've tried logging a few options and its not obvious which is producing less noise? thanks a lot, I know its been asked before I'm sure but I'm stuck

    Hi Ross, any chance of a base map to study to suit 2006 wrx w/ej255? cheers

    mixture map vs autotune; road tuning only

    cheers Adam, ill have a play see if i can get some more useful logs. any tips of number of samples required or is it a case of more is always a better indicator? sorry for the basic questions, just so much quicker to ask here than get frustrated and probably end up messing up what ive already got. cheers

    06 wrx g4+ CL Lambda issue

    all sorted but thanks for clarification, i literally just turned the input off for my narrowband so maybe had it set up all kinds of wrong. thanks for the help anyways

    mixture map vs autotune; road tuning only

    thanks for the reply, yeah I found cam timing to be a big player but I have avcs and timing just about dialled in. just after some insight as to which is a more productive way to go, definitely logging and analysis is a given with any change to the map really I find
  12. Hi again, abit of a question ive been pondering lately after struggling to iron out a reliable low load cruise map, would you use auto tune or the mixture map table? I'm finding auto tune does work, but seems to create a very lumpy table and is not always consistent. on the other hand, while the mixture map is very easy to use, its difficult to find settings that give a good data poll and are useful. obviously warm up, tip in throttle and gear change conditions are accounted for in both, so that being said which should I be using? all this is for low load, no boost driving, on a v10 wrx plug in g4+. strictly road tuning if that sways it either way (until I give up and pay someone who actually knows all this stuff haha) sorry if its abit wordy just trying to be clear, thanks guys

    06 wrx g4+ CL Lambda issue

    update for anyone who has this issue, it was exactly as said; narrow band oxygen sensor completely throwing off the lambda average, hence the steady fuel removal. removed the function from the narrowband and now I have a nice steady correction at idle, reacting to whatever target afr I chose using the average of one wideband sensor in the downpipe. thanks for the help again, I may be back with more questions very soon haha

    06 wrx g4+ CL Lambda issue

    just updated firmware tonight to latest version tonight so hope its not that. ill go have a play, I think itll have something to do with the lambda average being way out because of the narrow band, if I cant get anywhere ill post up me map and a log showing what I'm up against. thanks for the help, ill post me findings either way

    06 wrx g4+ CL Lambda issue

    ok cool, no I'm not using dual channel mode. so if I check I have the lambda average pulling from the right source,as in my wideband rather than narrowband, it should work as intended? anything else I might have missed?
