All sounds really good! Great for the budget in mind. Let us know how you go with your results, will be interesting to see how it goes with some finer tuning.

ok, i pulled out my Wolf plugin because running in multipoint it couldnt control my injectors (870cc) at light loads. Has any one run injectors like this with standard ecu re mapped?

sounds good man. drakhalf is what im gonna do too. keep me posted.

Hyped 6 I think to control 870cc injectors at light loads you really need to be running sequential injection which the stock ecu does not do. With injectors that large i'm also assuming you are making a fair whack of HP which is really beyond the scope of even a remapped standard ecu as it runs MAF as opposed to MAP sensing. The MAF just can't meter that much air.

Yeah thats what I was thinking..... the wolf would get to 1.15ms at idle and it would fall over. Still running .8 lambda. Was thinking that maybe standard ecu could have more powerfull injector drivers and actually open and close em...... Any one reached the limits of a single Q45 (i think thats them) AFM? I can sqeue the voltages to give me less resolution up hi but more scope

I think they fall over at about 300rwkw ish, don't quote me on that but i think it's ballpark.

k. lookin at slightly over that..... might be a bit of a stretch.

How much power can be made with the stock afm and a different one like the z32 or Q45. I want to run GTR injectors with either a chip or a nistune board.

As far as my knowledge of the Nistune goes nobody has done a decent vl on one as yet. Apparently they have been fitted to approx 20 or so cars but most of them have just been remaps on near std setups. Therefore no one can tell how far the std AFM will go. I believe they are also looking at converting them to sense MAP aswell.

hrmm interesting, im thinking of pushing mine sooner rather then later. nistune board. gtr injectors. turbosmart fuel reg. rajab copy plenum 300x600 cooler highmount 38mm gate with screamer. GT3082r manual 3 inch mandrel dump and exhaust. NA motor un opened AFM in cooler piping 250 kw anyone? ps id prefer AFM over MAP sensor anyway. there are pros and cons for each.. Some original photos have not been recovered yet.

Any news on the nistune boards?

What are the CONS to a MAP sensor? I can only think of advantages over a dodgey old AFM? Biggest advantage being no restriction in the pipe work?....

mmm, There is huge overlap in the debate between Manifold Air Pressure (MAP) and Mass Air Flow (MAF) methods. However, if you go back to basics, the MAP gets a representative indication of the engines demands for air whereas MAF precisely tells you the engine demand. This means that if anything changes with the engine than MAP is an approximation and cannot handle changes in pressure drop. MAF on the other hand can. As soon as you change anything on the engine which changes the air flow and (for stoich) that means power then if you have MAP you are compelled to change the ECU maps, with MAF you dont need to. The MAP sensor can only detect pressure drop in fixed pipes/air filter/cams etc The MAF sensor measures mass air flow, ie the Actual weight of air the engine ingests, this means it works over a range of pressure, temperature and velocity, and does not require fixed pipes/air filter/cams etc in that it handles all the variation. The same is not true for MAP. Example:. Tune a MAP engine for the standard air filter, change the air filter and its associated pipe then the ECU cant tell (from the MAP) that the engine is actually sucking in more air for the same pressure drop therefore there is a fair chance you will lean out an engine. Tune a MAF engine for the standard air filter, change the air filter and its associated pipe then the ECU can easily tell (from the AFM) that the engine is sucking in more air - so the ECU injects the correct amount of fuel, so you wont lean it out at all. MAP is also not much use if you go from sea level to higher altitudes above say 1000m - if you expect power and emissions unless you have a MAP sensor just for air pressure and compensate accordingly. The pipe work for a MAF doesn drop that much pressure. In my book, for street use, a MAF is ideal. MAF is selected as the primary and best method for emissions control, MAP might be used but on stock street cars that dont change much... For racing use, where you can change ECU maps and want that 1 to 2% extra then MAP is easier on the amount of plumbing. Thats it, you decide on your goal and expected outcome you expect to achieve, Cheers

Update guys, I have been using the Nistune board and software extensively during the last couple of weeks. Have to say its ****in awesome having the ability to tune and log the factory ecu in realtime. I haven't found any major bugs in the time I have been using it. I've had 3 different aftermarket ecu's in the car in the last 12 months, all with lots of downsides, finally the nistune software is up to scratch, I purchased the kit of Matt and have been impressed ever since. Drivability is as good as factory. Worth every cent. Controls atleast 500cc injectors as accurately as standard size, so will go even larger if you want it too. Good news is its now known how to modify the ecu to suit the Z32 AFM, which is good for people that want to push 300rwkw or so. If you have been thinking of it and have some tuning or efi knowledge, go for it Some original photos have not been recovered yet.

i am looking at it too but i dont want to be a guinea pig i just want to run gtr injectors

What sort of setup are you running yours on RB30? I'm the same, been running the Nistune board for a while (as my posts above). Couldn't be happier. I'm just running vlt injectors on an NA high comp setup (10psi). Heavily modified the timing map, not sure on the power, i'd say 175rwkw-ish. Made 140 on 6psi. Keen to know how it goes on a larger setup. turboluke, there should be no problem whatsoever running larger injectors, as simple as retuning the injectors constants. Note of course that within reason, the vl computer runs multipoint injection, hence, with big suckers (800cc+?)you'll struggle to control them at low loads.

hrmm sounds interesting, but ive been talked into lt10s, but still would really like to try this,

gt30 will be bolted up within a few weeks, i just want reliable power and not chasing kw, ill be content with 220rwkw 400 plus the z32 afm brings the total to around what a link ecu goes for yet to look into what live features the link has, does play nice in real time? options, options, options. want to get car running first with std ecu and make sure everthing is sweet before ecu swap

thats what im doing, just getting my ecu changed to standard vlt spec but with 440cc injectors, and runing min boost, then ill weigh up my options
