Thanks jibberjabbs,
I just ordered one

earlier today,
I also ordered the Acura RDX Injector from Bernardi Acura,
they are having specials too, Free shipping...

Now, time to decide whether I am going with AEM Piggy Back and
Boomslang or with K-Tuner...
well, I will have plenty of time to think...

 

^ nice. Who did you order it from?

 

Congrats BMWAlpina on the Sprintex I know you have been planning it for a long time. Even with the pending p2227 issue, I dont understand why you would consider an AEM over a reflash? A reflash seems so much simpler to implement and tune.

 

Just ordered mine! Thanks Jibber!

 

Welcome to the club!

 

Hi Boostedtaco,
I ordered mine from SuperCharger of Oklahoma City,
How about you, where do you orders yours from?



Hi Jibberjabbs,
The reason I prefer AEM is because I can easily unplug the wiring on the piggy back and back to stock without any need to reflash.
I plan to keep this car for a long time
and I worry 8 years from now the KTuner module to reflash broke down,
and if at that time KTuner is no longer in business (not that I am saying it will), or if KTuner no longer have hardware that support our ECU,
then I will be stuck and have to buy new ECU and at that time
it might be expensive...

but on the other hand,the KTuner method is much cheaper
then AEM
because with AEM the boomslang wiring along is over $623 now...
not to mention the AEM F/IC-6 unit and the dyno tuning cost,
so the KTuner method look more attractive now...
still
I wish KTuner already had all the features available for Supercharged application...

well, I have few weeks to decide
I need to install my custom exhaust first anyway...
Thanks again

 

Thanks, glad to be here. Now stick with SMT8 or go k-tuner....I rather not dump another 1k into this.

I got mine from Sonic Motors. If it wasn't for the ice/snow in OKC, it would be on its way.

btw - is it worth it to get rid of the restrictor?

 

Hmm... Mine is already on UPS truck today... also from OKC...
suppose to be here Next Thursday

I think it is worth it to get rid of the restrictor
because Gary from Sprintex remove it from their Demo Fit too...
and he say the Asian Tune Sprintex manage to get more power
after removing it...
I am removing mine for sure

 

I am currently researching more about K-Tuner,
What do you guys personally thing,..

Which one of this BETA features below is the most important / benefit
for our Sprintex Supercharger Application?
1. Real Time Tuning
2. Injector Sizing
3. Adjustable 2 step
4. Anti-Lag
5. Custom Map Sensor Support
6. Speed Density Fueling
7. Expanded Table for Boost
8. PWM Boost control

and if I am not mistaken, BETA means it is NOT AVAILABLE yet?

 

1. Not used if you are going to etune.
2. Can be acomplished with adjusting MAF fueling chart
3. How much drag racing do you plan on?
4. Only applies to turbo
5. Only needed if you plan to excede 10psi
6. would be a nice option for extreme setups
7. Would be great, but the hpd crz gets along fine with 10 cells
8. This would not apply to a sprintex setup

 

My Sprintex arrived today,

I do have few questions,
First I want to make sure mine is for the USDM Version with EGR,
can you guys please check based on the pictures below that
mine is really the right USDM version with EGR:








The reason I worry because on the packing list on the packaging
it say NON EGR Version
Ok it say Honda Jazz (Concept-2) NON-EGR Supercharger kit
Top Level 244A1011,
here it is:



I hope this is just because Sprintex print the wrong packing list.
because based from the pictures on the installation manual.
it looks like mine is the correct USDM with EGR version.

Second,
I think mine is the NEW CONCEPT-2
because on the packing list it say
Honda Jazz PLUG & PLAY Wiring Harness,
and it also have the TMAP Sensor !!!

Please take a look at this pictures below,
and tell me if you guys have this kind of wiring
in your kit or not...
but, hmmm
I think mine is really plug and play
since there is no open cable/wire to connect/splice
to factory ECU...

Is this Plug and Play Cable?




How about this cable,
it have connection to the SMT8 and to the Plug and Play
Cable too, and it came with the Tmap sensor !!!



Now if this is all truly the new Plug and Play wiring system,
hopefully it is fully compatible with USDM Honda Fit,
since it is suppose to be Honda Jazz NON-EGR as printed
on the packing list...

What do you guys think?

Oh the SMT8L-V4 suppose to have the
Jazz Calibration 244P6115...

What do you guys think?
Thanks

 

On the other hand, look like Sprintex make modification to the INLET RESTRICTOR,
I remember the old version had 3 weld that can be grind so it became NON Restricted,
this version, the restrictor is CAST into the whole intake,...
so It is NOT possible to open the restrictor as easily unless a machine shop do it for me
here are the pictures:





vs. the older version:

 

^ Looks like all the EGR mounting is there, you should be OK. There are no plugs in the holes to the EGR itself , are there?

That plug and play harness will sure make things easier!

So you gonna give the SMT8L a shot?

That inlet restriction kinda sucks. Just more grinding though!

 

Hi JibberJabbs,
Thanks so much for all your reply and information.
I really appreciate it

Do you know if SMT8L have the capability to do Injector Sizing?
because I am sure I prefer to remove the fifth injector and
just use the 4 larger Acura Injector that I already bought anyway.

I also want to remove that fifth injector and put a blanking plate.
Do you know any good source for a blanking plate that fit to cover
the hole left by removing the fifth injector?
(EDIT: I read your previous posts where you show you put a gasket and
modified with shorter bolts, Great Idea, but I wish someone
made a proper blanking plate... hmmm.. I need to get a custom one machine...)

I am really tempted to use the SMT8L now,
because from what I remember,
some member here actually still use SMT8L without much problem
after they replace the fuel pump with the higher flowing one...
and the problem that some face before also caused by the first generation kit wiring that have connector that is loose,
while I think on this one they had improved the connector...

This way, I can wait until K-Tuner have all the features that currently in "BETA" become available before I buy it.

I am just not perfectly satisfied to buy a product (K-Tuner) knowing that
it can have more functionality but it is not available yet (still BETA) without
guarantee that the BETA Feature will be available in the near future
(or even continue be developed at all).
K-Tuner had told me that if the feature become available,
it will be a free upgrade but I am sure I still need to pay to retune it again
with the expanded fuel map and the injector sizing feature.
On the other hand,
I completely understand that with a very small user of Sprintex Kit, it might not be economically feasible for K-Tuner to fully developed
all this Beta features and recoup the R&D cost and as K-Tuner had pointed out, it still not prevent TurboGixxer from successfully tune Honda Fit with
Supercharger kit with K-Tuner...
but still, I just want to buy a mature fully developed product,...
I am just obsessive with perfection...

so if this SMT8L function then I can wait until K-Tuner had all the
BETA features available...

by the way how many people on this forum that use Sprintex Supercharger tune it using K-Tuner?
I count 2 so far, You Jibberjabbs and Portron... anybody else?


Thanks

 

Hi Guys,

From what I understand, both of you run the MAP Sensor to read the boost by connecting it to the Sprintex Intake Manifold (after blower) vacuum lines, I don't think My Concept-2 version have that though...

How about this vacuum outlet on this picture below,
I am talking about that brass nipple that are still covered with SEAL?
can it be used for the MAP sensor?
Is it after blower?

If it is NOT after blower, then anybody here know
where I can get a MAP Sensor and Boost Gauge connected?
Sorry for all this silly/basic questions,
I had not done a lot of research myself since I just received this kit
yesterday...

EDIT: I finally read the install manual, and mine had the T-MAP sensor bolted
directly to the intake port on the sprintex... so I think this solve the problem
for MAP sensor reading, but how about boost gauge... my guess is
connect to engine block vacuum line or something like that...
this going to be an adventure for me, never have a car modified with aftermarket
turbo or supercharger kit before

Thanks

 

^ The Ktuner route is going to be less perfected for sure. There are only two of us using it. It was never developed like the Sprintex kit was. And there is still the p2227 issue. The Beta features don't really bother me, the only one I would like is the extended maps because it add resolution and could possible smooth things out.

My motivation to change to the Ktuner was to fix the occasional limp mode and have a better tuning option so I could use etuners.

I have not seen proof that a larger fuel pump is needed.

My advice would be to run the 5th injector with the SMT8 for a few reasons. The SMT8 software interface and USB drivers suck, and very few tuners have experience with it. The SMT8 doesn't really control the stock injectors it only modifies the o2 sensors signal to trick the ECU. The fifth injector is the only one directly controlled by the piggy back.

With that new piggyback harness you could probably install the kit with the smt8 in realistic 4-5 hours. Why not start there.

Also in reference to your MAP sensor questions: Some of the CRZ guys have the TMAP sensor manifold and have discovered they can fit the factory MAP sensor in the TMAP opening with the addition of an o-ring.

 

Yep.

I don't like the concept of the 5th injector, which is why I went with K-Tuner. P2227 still exists but it's whatever.

BMW Alpina, You can use a digital boost gauge that will calculate boost off of the MAP sensor readings, read back a few pages and we discussed using our phones to accomplish this. Not sure what the T-Map hole looks like but I bet you could rig something up and buy a T connector and run two vaccum lines off of it.

I agree with Jibber that I don't think a fuel pump is needed. Oh, and it was by far the worst part of the entire install. That blasted plastic O ring is literally the worst.

Anyway, I'm happy with the tune and kit so far.

 

Hi Portron,

Yes, I totally agree with you, this past few hours I had been thinking inside my head eventhough I suppose to work at the office thinking about my work hahaha
and I had decided I am NOT going to use the SMT and 5th injector set up.
it is NOT a perfect solution,
I also think that the 5th injector were forced to work to hard because
it had to accompany every pulse of the 4 injector this mean it work at speed / intensity of 4 injector and it will never be able to keep up properly.

Regarding the fuel pump,
I think my Denso Fuel Pump will not have the problem with that O-Ring,
because it had different barb design.
well we will know when I install it,
I need to open the center console anyway to change the parking brake cable when I install my RS rear Axle soon, so that is when I plan to swap
the Denso Fuel Pump

Now, I am going to wait a bit longer since I am busy now anyway...
in about 1 or 2 months when am ready to install,
if by that time K-Tuner had not ready with the expanded fuel maps and bigger injector adjustment, then I am going to go with AEM F/IC-6...

and Portron that idea about getting the boost reading via vacuum hose
from the T-MAp hole is a good idea, I just haveto find the fitting/machine one. Thanks

 

Ah, I was talking about the big giant plastic O ring at the top of the fuel tank, not the small little rubber one inside the hanger. Thing sucks to get off and put back on correctly. I have an Evo-X fuel pump.

Spraying fuel in with a 5th injector not directly in to the ports never seemed like a good idea to me (like the old school wet nitrous kits). Equal dispersion to each cylinder and such, and it just adds a level of complication that isn't needed.

The other appeal for me with Ktuner was not having to do any wiring or splicing anything. Just plug in to the ODB2 port, flash and go.

I had an AEM FIC in another na -> turbo car, and it was fine. You should email Turbogixxer and ask his opinion on this specific application (he tunes both).

 

Hi,
I did talk to Turbogixxer and he said he only tune with K-Tuner (eTuning) for our application...
