Ah, very impressive none the less. Ever plan on an LSD? I have one on my GE, and it makes a hell of a difference when going WOT especially when going around a turn.

Planned it? Nope. I did think about it a little though.

However, my lack of technical know-how along with lack of tools means I would need a mechanic to do it... and ATM, I can't justify that cost.

Right now, I'd just settle for not spinning one tire uselessly from stop.

Hey, guys.

Fit Thermal Intake Manifold Gasket

Any thoughts on this manifold spacer? Will it work on the GE8?

Hi Gary,

I talked to you on the phone last December and then

I had been trying to email you since February to this 2 email address:
'Gary Turner' <GTurner@SprintexUSA.com> and 'info@sprintexusa.com'
but I have not heard back from you.

so
While you are here,
I have a question,
Is there any plan for a Sprintex Supercharger kit that came with
Plug and Play Wiring for the Piggy back?
so no wire splicing needed as the first version of the kit?
If yes, when?

Thanks

It is still in development. The Honda ECU plugs are not easy or cheap to come by.

I saw that one too.

It looks like it will fit, its not a spacer but a gasket and replaces stock one.
I dont see why it wouldnt work as long as it lines up and its on my list of things to get. It should help with heat soak pretty good with the SC.

I had one on my turbo audi but as you know alot of heat comes from the intake air with turbos so the benefit is minimal on turbo applications.

Is Sprintex making a supercharger for the GK5 (2015 Fit)? I see a picture on the bottom of the website with the Earthdreams 1.5ltr GK5 engine. So I ask!

Nothing here on the 2015s, yet. I'm not sure when those will get here.

Hello!
This gasket is used for first generation of FIT's. Second generation has addional space for EGR valve.
Sorry for bad english...

I thought I would post a bit of progress I made with Ktuner. They had reached out to me to do a read of my ECU in order to add support for the 2011 ECU. So I got a deal on a end user reflash setup. Currently the software does not support forced induction, but Ktuners software engineer (and mabey owner/operator) told me that he 100% intends to add forced induction support and is already working on it. From our brief discussion it sounds like the CRZ guys are helping drive this development. I did not realize that the HPD supercharged CRZ has a honda provided reflash (and uses the same MAF as us). It looks like the HDP kit includes injectors from a v6 (16450-RCA-A01 maybe an option for us?)

Yeah, a bunch of CR-Z guys have been pushing for this since Hondata does not support the 2013-2014 models.

The only solution really for those years right now is Sprintex and people are looking at getting away from the 5th injector/piggyback setup.

We've been making a decent amount of progress with the Sprintex unit I think we have ~10 people with their unit (I have one as well).

I've been following this thread since the beginning. The biggest problems we've been having is that they make contact with the hood in a spot during acceleration, EGR flow code, and some of the guys have had knocking problems which ended up being defective piggyback units.

FYI---the factory MAP does not see boost in our configuration. We have to suppress its signal so it doesn't see too much vacuum.

For the Ktuner, it may need an external MAP sensor to read boost. That's what the 3bar in our kit is for.

These platforms are very similar, hopefully we can help each other out.

Gary brings up a good point. The HDP system introduces boost before the MAF and MAP, but our sprintex adds boost after. I suppose the MAP could be relocated to the boost side, but what about the MAF, does it need to see boost? Also the (stock) intake air temp is measured there.

ZF1Punk, Any CRZ guys figure this one out yet?

FYI, The HDP CRZ uses the stock MAP and MAF (which are the same as the Fit).

MAF does not need to see boost. You can't do a speed density on this kit.

The MAP is a 1bar unit that only reads to atmospheric pressure. replacing it with a 2bar unit would throw off the PCM parameters without proper reflash tuning. We don't use one because it isn't needed on this layout. The PerfectPower unit needs to see boost, but the stock ECU needs to be adjusted to simply keep it happy.

Hi SprintexUSA,

From your point of view, which one is simpler to Install and Tune with Sprintex,

The K-Tuner reflash (when it is available) or
the AEM F/IC-6 with boomslang wiring?

Mind you, I don't need the highest horsepower, just reliability plus
I plan to tune myself as much as possible just so I can drive the car
to be dyno tune without having the car on the flat bed truck.

I almost bought an AEM F/IC-6 few days ago,
but the post here about K-Tuner make me pause and wait...

The faster I can find the good tuning solution, the faster I will buy Sprintex Supercharger.
I don't want to use the current 5th injector set up...

My plan is to use RDX injector to replace the factory injector, I even already buy the clip adaptor for this from Jackson Racing

Oh, one more question,

the AEM F/IC-6 had been around for so many years and
it do not have the capability to ADVANCE the timing...
Do anybody here have heard any rumor about AEM updating it's Piggy Back line to a newer model?

It would be suck to buy the AEM F/IC-6 now and in less then few months, AEM had new better piggy back...

I also do research on another piggy back called MAPECU3,
their product can advance timing but unfortunately they are not controlling
the injector directly like AEM...
Which one is better for Sprintex Application the AEM F/IC-6 or MAPECU3?

Thanks

I have it from a good source (Ktuner) the stock MAP can go to 10.8psi. I will confirm when I can find a data sheet.

We still need to get IAT (after the compressor)into the ECU?

Gary, Could you provide details on the IAT that comes with the kit ? Part number ? I'm considering splicing it to the ecu's input.

I have had no luck finding specifications for the map or maf. Hondata claims the stock map can do 11psi, they also sell a 4bar direct replacement sensor. You also need to select the 4bar calibration in flashpro.

Regarding the AEM vs. reflash---I've only used AEM in limited terms on Jeeps. I like the interface. Duplicating the sensor tricks are the hard part. The mapping is very likely different.

The IAT in our kit is a 5v unit. They're accurate within 1-2F. I wouldn't try adding that into the factory PCM. You would be asking for trouble.
