Roman Posted May 10, 2015 Share Posted May 10, 2015 The 5.4.1 firmware update unlocks all of the options for free for the G4+. (depending on model I think) Sweet!Havent had much of a play with mine yet, but looking forward to getting knock sensing setup.It will be awesome to have knock properly integrated as one thing I've been hesitant about is advancing the timing without any feedback I can review. 1 Quote Link to comment Share on other sites More sharing options...

Roman Posted May 10, 2015 Author Share Posted May 10, 2015 whats the backstory? The back story is that you've got a G4 EDIT: Here's the blurb from the update notes:  New Features · Removed ECU feature unlocking.  ECUs will now have feature sets as per the firmware 5.4.1 feature differentiation chart.  Note, ECUs are still shipped as locked and need to be enabled but all previously purchasable features will become enabled after this firmware update. So your guess is as good as mine. On the forum, some people are raging that they paid for an update thats are now free, even though they now get the rest of them for free they aint happy that other people get the same thing.

sr1600 Posted May 10, 2015 Share Posted May 10, 2015 Been thinking about ditching my oldschool link and going to a g4 atom, dont really need all the outputs for what im doing Is the atom alright? Quote Link to comment Share on other sites More sharing options...
Roman Posted May 10, 2015 Author Share Posted May 10, 2015 I think it just comes down to how many inputs/outputs you need/want. Â If an Atom can do everything you need, then there's no point spending money on something more. Quote Link to comment Share on other sites More sharing options...
sr1600 Posted May 10, 2015 Share Posted May 10, 2015 Assume everything else is the same? What doe everyone use all the imputs/outputs for? Quote Link to comment Share on other sites More sharing options...
Roman Posted May 10, 2015 Author Share Posted May 10, 2015 You can have a look here for the comparison: Â http://www.linkecu.com/products/engine-management-ecus/g4plus-feature-matrixIf you just want it to do the same as your existing ECU but with a nicer tuning interface etc, then yeah Atom will be awesome no doubt. Â But if you want to setup things like flat shifting, launch control, nitrous, knock sensing, gear detection, shift lights, warning lights, dash switches, etc etc... Â Then you might find that an Atom doesnt have enough inputs or outputs.I've been using the extra inputs and outputs for things like datalogging MAF sensor values, extra temperature or pressure datalogging, clutch switch for launch control, speedo signal for gear detection, outputting to a configurable shift light, and a few things like that.Some people use switches for things like turning on NOS, switching ECU maps, switching boost level, turning traction control on/off, setting a pit lane speed limiter, and... what ever else you can think of really!So if you want to tinker with things then in my opinion the more inputs/outputs the merrier. Â But if you just want to wire it up, get your car tuned and leave it as is - Atom or Storm will likely do everything you want to do, easily.If you're looking at some options for a new ECU and are going to be tuning it your self or using for datalogging or whatever, I reccomend downloading the software and having a look first... As you'll be staring at it a lot later on so you want to make sure it suits you / runs on your PC / whatever.Most ECU manufacturers seem to have free downloads for their tuning software. 1 Quote Link to comment Share on other sites More sharing options...
mjrstar Posted May 10, 2015 Share Posted May 10, 2015 Atom is OK for a basic 4 cylinder setup. Configurable outputs to set up both sequential or batch for injection and spark. But not a lot of spare inputs /outputs for "cool" stuff. I have an atom in the MX5 I got unused second hand for cheaps. If you are going 6 cylinder look elsewhere. .. 1 Quote Link to comment Share on other sites More sharing options...
Stu Posted May 10, 2015 Share Posted May 10, 2015 Agree - the atom version is fine for most basic setups but doesn't leave you with much scope for options.  I run a Storm and after including a few options and inputs (fuel and oil pressure, speed sensor etc) I've basically used all the inputs/outputs. Quote Link to comment Share on other sites More sharing options...
downtrail Posted May 10, 2015 Share Posted May 10, 2015 As above but in saying that ive run a few 6cyl rbs with atoms these are basic setups. Just got to watch injector sizing as itll have to be batch fired but in doing so you free up 2 more aux outputs from the un used ign and inj 4 channel so you end up with 6 outputs as opposed to running a 4 cylinder sequential.

mjrstar Posted May 10, 2015 Share Posted May 10, 2015 How big is too big? My mates 2J is running Bosch 2200's group fire on an upgraded G3 and it'll idle happily at 700 rpm if you ask it to. It may not be suitable to run the old indy blues at really low duty cycle but most of these newer tech injectors have awesome low Idc control.... Personally if group fire injection can be avoided that is my preference, although waste spark is all good (with dual post coils) 1 Quote Link to comment Share on other sites More sharing options...
downtrail Posted May 10, 2015 Share Posted May 10, 2015 Ive had trouble with simens 666s and id1000s at low pw keeping them consistant was near impossible. Even with a whole heap of timing thrown at them they were too unstable. These were with link pluses. I have how ever run the 666s with the older atom fine on a similer setup. And also with a megasquirt with only 2 injection chanels! Quote Link to comment Share on other sites More sharing options...
sr1600 Posted February 18, 2016 Share Posted February 18, 2016 Anyone run a flex fuel sensor on a link atom? Quote Link to comment Share on other sites More sharing options...
Roman Posted February 18, 2016 Author Share Posted February 18, 2016 I'd say it's not really practical due to lack of inputs and outputs on an Atom.  As although you can wire in the flex fuel sensor itself, you need to run modelled fuel calculation which really needs fuel pressure and fuel temp inputs to be accurate.As well as very accurate deadtimes etc for the injectors.What sort of motor, out of interest? Quote Link to comment Share on other sites More sharing options...
sr1600 Posted February 19, 2016 Share Posted February 19, 2016 Sr20det in a Datsun 1600 - the more I look at it more I think ill just stick with 98 Â Either solid lifters or sr20ve head and rev it through to 8500rpm , if I need to make more ponies.................. Â Really don't need much in a sub 1000kg car " but me love them revs " 4 Quote Link to comment Share on other sites More sharing options...
Roman Posted February 19, 2016 Author Share Posted February 19, 2016 E85 is too much of a pain in my opinion. Not much gain on NA but using a shitload more fuel. Yeah max revs is the way to go!! Quote Link to comment Share on other sites More sharing options...
Rookie Posted February 19, 2016 Share Posted February 19, 2016 Lol, so uninformed Roman, e85 is great for everything, the only downside is availability in nz. On your beams you would probably pick up 10-15 HP without changing anything. Quote Link to comment Share on other sites More sharing options...
