Rb25Det D-Jetro Power Fc

[89CAL]

I was asking so I wasn't providing answers for

something different..........

As far as I remember its a 2 bar map sensor

There is no launch control

You can use afm if you want

No idea but fc edit should work

They are a re-flashed 26 d-jetro and if you do the data init you have to send it back to nengun so they can re-flash it. Other then that you get everything to make it work on a 25 with map and IAT

sorry and just to check also is the an APEXI legit product or a special nengun release?

i always questioned this and it wasnt clear

IF its a legit APEXI release you should be able to DATA INIT when ever you like

If its a non legit release and you have to send it back when you want do DATA INIT each time I would advise caution with this product

this sounds worrying and i would not purchase this. DATA INIT can help to fix f**ked idle and other issues

there should be no reason a legit Apexi purcahse requires re-send to supplier to do DATA INIT

youve been warned and i would question this

this sounds like its a BCNR33 powerfc djetro with a special remap to make it work on ECR33

vs a legit ECR33 powerfc djetro version where you can DATA INIT as much as you like

it doesnt make sense because DATA INIT would load from its nvram

This is how I was told it was, I'm not sure who is doing the reflash (As in if its someone from Nengun or some tech firm in Japan doing it) but they wont release the data to update it to the power FC for yourself (For obvious reasons) which is the main reason i was put off

Other then that the kit comes with map sensor IAT sensor and everything you need to plug it in and go

Having said that though, I cant find it on the Nengun site anymore.....

[paulr33]

it just sounds like a beginners trap

ive seen people data init by accident and ive seen friends play with the hand controller and data init too

data init the unit once

and its basically a paperwork which needs to go back to nengun to be fixed

if you data init and your away from home theres no way it will start on BCNR33 maps and default tune

so youd have to tow it to get it home. ASS

it should be on the nengun site under NOP

dont get me wrong

its a massive breakthrough in being able to basically do what AP Engineering were doing

but its ass that when you data init, its a bcnr33 powerfc

i actually wonder what is being changed on the pfc to make it work with ECR33

if theyre just parralleling up the input sensor to make it work

then technically if you data init the unit and enter a series of key presses on the hand controller this is probably the same thing

ie does the djetro ECR33 come with some special firewamre that actually says ECR33-D in the /etc/version or does it just say BCNR33-D and its just a series of tune settings

if its just tune settings you could do it yourself with a bunch of key strokes on the hand conrtoller

sure it would take a while, but would save posting it to nengun

Hi i would like to know if anyone has tried the rb25det D-jetro Power FC as yet. (R33 RB25DET)

1. what is the MAP sensor limits 1 2 3 bars?

the apexi standard map sensor is a 3 bar map sensor. but dont be fooled. this doesnt mean you can run 3 bar boost.

map sensors (all not just apexi's one) are rated in total pressure and not positive pressure or "boost"

3 bar map sensor means -1kgcm2 for vacuum and +2 bar for positive pressure

so if you want to run more than 2 bar boost using the apexi kit you need to change the map sensor and recale it using datalogit

2. Can i still use the AFM if needed.

no you cant. models are fixed. ljetro is afm, djetro is map. you cant mix and match or change

3. Is there launch control.

no there is not

4. Can the old Data logger work with it. or software update needed??

yes datalogit will work

5. what do you guys think about it.????

same as ljetro but with map sensor input instead of airflow meter

some tuners swear by apexi djetro and others hate it with passion

ive heard more good stories and tuners talking good about it vs those talking bad

the main thing that is crucial is the installation, dont f**k with the install or be a spaz

read the instructions and install it as per how apexi intended it to be installed

most issues come back to how its installed

Hope that all is well, thanks for just keeping it simple, you were always good at that. lol

Cause of you i'm a good Power FC tuner. thanks a million,

after the item arrives i will tell you all what i think of it.

do you know if it has two map sensors like the RB26 Power FC???

I'm pretty sure that what they'd be doing is mashing the normal RB25DET FC's firmware with the 26 D-jetro firmware, taking what they need from each. So, they'd want the code that handles the MAP sensor and IAT and turns it into the load index from the D-jetro firmware, and they'd want the code that handles all the rest of the RB25 sensors from the 25 FC. Massage a few things so that it works with only one MAP sensor (shouldn't be too hard), and you're away. Probably have to do the same with a few other little things like idle control and whatnot as well.

There's plenty of clever people around who do that sort of hacking these days. The best (oldest) example was mashing the Canon 10D firmware into the 300D to open up a range of features from the higher end camera on the lower end unit. They had to pull some tricks to access some of the features using buttons the 300D had, because it didn't have the actual buttons that the 10D had.

This is about right (with vct also) from what I was told. If you go to the information screen on the HC you will see 26 d-jetro most likely.

I can't find it on the nengun site anymore but.....

[paulr33]

it would only have one map sensor as its single turbo rb25

[MJTru]

thanks mate i raising help with them right now with all your points. I have a family member in japan that is helping me and i asking for a full refund.

so sorry i wont be able to add any more info. That sucks.

i made a rb26 PFC L-jetro work on a ECR33. now I'm wondering if i can make it work on a d-jetro version as well????? i guess it would be a good task to try. have you heard of anyone doing it. The vtc was controlled by a MSD trigger switch.

thanks to everyone

I thought the 26 d-jetro's only had one map sensor anyway. There is no need to moniter the manifold pressure with 2 pressure sensors....

bcnr33 (or any gtr) djetro has twin map sensors

the powerfc uses both map sensors and both should be installed and used

people have gotten the GTR powerfcs working RB20/RB25 no problems and it requires some exrtra work

the main difference is they are cutting wiring, splicing wires, changing a heap of settings and doing all the tuning

its not off the shelf and the cars loom would be modified to suit, or a boomslang in the middle modified

a few years i actually bought a boomslang cable and the supplier was happy to template from what i had done (wiring changes) to make a GTR pfc work on ECR33

so you could basically order a BCNR33 PFC and this special boomslang and punch in a few settings and it would work on an ECR33 but i never got around to it

this was when mafia got a stock BCNR33 working on his ECR33 properly. this was back when ECR33 was discontinued

Ah thats right I remember seeing the 2 map sensors when I looked at the instructions for my boost control kit. Is the point of having two purely because there are usually 2 MAF Sensors or is one for boost control and one for calculating load?

This is probably in your FAQ, I'll have a look

Someone link me to the ecr33 d-jetro? I can't find it on the site anymore

That's the only thing I could find.

There's 2 because of the 2 AFMs. They simply bodged in speed density calcs for load determination in place of the VQ curve lookups.

Apexi MAP sensor is 1.7 bar (at ~4.5V) boost pressure sensor.

You can connect any MAP sensor, as long as:

1) you have the right connectors on both ends when making custom wiring harness.

2) know the sensor parameters. See http://1jzmerc.com/hks-faq/hardware/#map for a list of MAP sensors and parameters.

D-Jetro RB25DET PowerFC (4E14BN32 and 4E14BN33) is legit - but limited to Power Excel workshops - according to http://www.apexi.co.jp/pdf/products/p_fc.pdf

[paulr33]

if its a legit product then you should not need to send it back to apexi or nengun when you do DATA INIT

i cant image any ap engineering model needing to be shipped back for DATA INIT

so if the one you buy requires to be shipped away for DATA INIT and its "legit" then its absolute ass as per my previous posts, beginners trap
