Ive noticed at interstate speeds, my TII will go out of closed loop above 3500 rpm, which is only about ~78 mph. It would be nice if you could make the closed loop start/stop points user-changeable in rtek.. so you could dial in extra gas mileage when cruising above 78 mph. another reason would be so you can temporarily disable closed loop, so you can tune the vacuum fuel map more easily

 

very true^^

 

Noted.

 

Maybe more(2 or 3) aux inputs that can be logged... Not sure what this would entail...

AFM removal, base maps for a select injector/turbo combo (maybe hard because of engine effencies/porting), more injector selections.

I'm waiting for 2.1, but maybe for 2.9, hydrogen, e85, methenol fuel maps. (maybe even plutonium...) just kiddin

Good luck, Thank you Pocketlogger Inc. for you hard work and dedication to S4 rx7 owners!

 

2 aux ins will be available on the 2.1 (var resistor and ATP)

 

will the v2.1 be avalible by the end of the year?

 

pre-maps for BNR Stage 1 2 3. Is that asking for too much?

 

Not if you are supplying the cars.

Actually on a serious note since it was mentioned twice, DTI designs and manufacturers engine management electronics, we aren't in the tuner market. IMO, supplying predefined maps is a recipe for disaster. For one, every car is different so I could never comfortably give out predefined maps. I don't believe in the one size fits all approach to tuning. Second, the whole point to the rtek is to give you the user power to tune. Having predefined maps available will encourage people to buy an rtek and feel the predefined maps are adequate without learning anything about tuning. As it is already, people buy the Rtek without knowing anything about tuning... but at least they know the ecu is basically stock from us. The predefined maps will give the uninformed a false confidence that the tune will automatically be fine for their car. We simply don't want that liability.

But theres nothing that says the community can't share maps.


Would anyone have interest in a website that you could upload, view, edit, and share maps with other people?

not being a wiseass, but just want to point out that all the 1.x's ARE predefined maps in the form of a stock map with the DTI tweaks made to them.

as it is now, you cant export maps can you? it would be nice if you could open the maps in excel format or something to edit them on PC

 

I know the idea of the r-teck is to avoid the need of using a laptop for tuning, but laptop based software would be nice. For those of us that have laptops and don't want to buy a PDA.

 

How about the ability to View/Edit saved maps on the palm without having it connected to the ECU. Editing maps is a bear sometimes because holding the PDA in my hand makes the serial connection disconnect every once in a while. If i could download the map from the ECU, edit it, then upload the map to the ECU it'd make that a lot less of a headache.
(I've got a Palm V and a Palm TX and the connectors on both of them are so picky. Any suggestions?)

Alternative fuel support would be freaking cool, though i think some engine mods are in order to run things like E85 (won't that mess up the water seals?)

 

screw all that other stuff just delete the afm... then work on adding 720cc/1000cc preset and external map sensor

 

presets are not a good idea.. why would you need a 720/1000 preset anyway?

When they make a preset map, they are basically pulling enough fuel so teh bigger injectors act like stock 550s.. if your setup needs that much fuel, why would you want your injectors to act like stock 550s?? think about it

 

That's not quite how it works. Most ECU firmware use a global IPW multiplier and a map lookup point. When increasing the size of injectors, you change the global multiplier, not the values on the maps. There's a few other things that need to be tweaked such as injector latency and tip-in values, but that's more injector (and ecu type) dependent. In essence, yes, whatever size injectors we're compensating for do act like stock injectors, but that's what we want. Mazda spent a long time getting the fuel system to run as well as it does, having larger injectors mimic the stock injector characteristics is not a bad thing.

With that said, when increasing the size of injectors in stock firmware, other considerations have to be taken. The stock maps are the largest limiting factor. You may have enough fuel to supply x horsepower, but your maps load calculations max out at a load point far short of the amount of air you are flowing and you go to static value at peak torque. IPW caps and fuel cuts are other limiting factors, but those are easily removed, and they already are in the Rtek line of ecus.

 

that not a good idea. every motor is different, all injectors dont flow exacly the same as others, some streetports are alittle bigger/smaller than others. that variance could be enough to blow ur engine. its good to learn how to tune yourself like i did so that way you know what your doing. otherwise i would just recommend paying someone to tune it for you.

 

that would be a GREAT idea

 

screw pre-made maps. Take 5 guys running BNR stage 3s. At least 3 of the 5 will be running different intercoolers. And thats just ONE big factor to be considered in a pre-made map.

You buy the rtek so you can tune yourself! And it would take ALOT of time away from more important things.

What is NEEDED is AFM removal.

What I WANT is laptop tuning software and bigger injector presets.

 

Another way this makes a difference is that there's no defined place on the maps where your secondaries are on or off. This would make tuning around the staging to compensate for larger injectors a bit tricky since you can't tell exactly where on the map you're adjusting for both the primaries and secondaries, or just the primaries.

If the staging is based entirely off boost and RPM that's not a problem, i might just have no idea what i'm talking about.

 

Its not what you want

 

afm removal,more injector presets,and also how about a 2-step launch?

 

how about aditional injector drivers/control to run 2 or 4 addional 550 injectors. and another count for the afm removal.

 

Maybe we should just let them finish the S4 turbo 2.1 and then put out the S5 turbo version. THEN we can make suggestions about future add ons.

 

+1 for afm removal.

 

huh??


well right now, its based entirely on boost and rpm (above 0 psi AND above staging rpm).. but the latest revision makes staging load based, so i think that may cause a big headache trying to tune with different sized secondaries
