Hi Steven,

Where did you bought the BS229 O-Ring from?
I see some vendor on eBay but do you know any other source beside that?
Thanks

I got impatient and had my mechanic install the supercharger with the new PnP harness. It's bolted up but....

i'm having issues with the plug and play harness....

With everything installed, start the car, limp mode instantly and check eng code is P2647. After swapping the vtec switch and the car still has that issue even after doing a ckp reset with HDS.

My mechanic traced some of the wire down from the vtec solenoid and he suspects the pins may be wrong as there is nothing from intermediate harness to the ecu from the vtec solenoid.

He connected the car back to stock and the car started fine with no check engine light.

Soo i'm thinking maybe i got the wrong PnP harness? Does anyone have pinouts of the new PnP harness? maybe it would be a simple re-routing of the wires.

And we've manage to break the nipple on the bypass valve. Is VA764A the correct one to order? is there one with a metal nipple on the valve?

 

Sounds like you have had a bit of bad luck. Even though I have not used the new PnP harness, assuming it still has the same connections as the old style spliced in harness. Maybe I can shed some light on the subject.

There are only two pins that are intercepted by the piggyback (the other 4 connections are T's), MAF (connector B pin31) and CKP (connector C pin32) . All the other wires on the harness should be straight through connections, so you should be able to test them all for continuity. The older versions of the Sprintex install manuals include this information (back when we had to splice all this stuff). Good luck.

 

Just a tad bit of bad luck. It's par for the course it seems with my cars. haha.

I sent an email to Gary, he mentioned he's heard of my issue before and told me to try this, i'll give this a whirl tomorrow. Hopefully it fixes it.

 

I just bought a Hose Barb Reducer because I realize
the Forged Steel Adapter Fitting 90 Deg 1/4 BSPT BSP Male - 5/16" Hose Barb C12-2

Kinugawa Barb Fitting that I bought have 5/16" Barb Outside Diameter,
while my Defi Turbo Boost Gauge hose is only 4mm Internal Diameter.

so I bought 4 type of Stainless Steel CNC Machine Reducer,
because I don't really sure which size will fit better since their sizing
is not exactly 5/16" nor 4mm...
turn out the right reducer is the 5/32" vs 3/8"
I also bought some industrial grade Teflon Tape.
Here are the pictures:

 

After careful consideration,
I decided to return the AEM Water/Methanol Injection Kit that I bought from Amazon.

I think I will stick with just 4 larger RDX injector, remove the 5th injector
use the AEM F/IC-6
and also buy a Ventilated Hood to help cool the engine bay temperature.
I know that I need to have it tune more conservatively,
but the risk of a water/methanol injector failure causing engine hydrolock
is too big for me.
My goal is to have a car with more reasonable power than stock,
but not going to aim for maximum available power.
I also decide to stick with stock pulley for obvious reason.
oh well, better stay safe since this is a daily drive

 

She's alive!

Thanks to Gary's and Jibbers tips it's installed. Had to run the vtec switch wire from the PnP harness to the chassis harness.

Now to the to next thing....We didn't have a way to drain the gas, soo we did a half 87, half 93 and 2 bottles of octane booster. I wanted to get some toluene but the paint store was closed.

With some light pulls it runs good, no pings (that we could hear) then until we come to a stop and get a check light for EGR p2413. Anyone have this issue?

We clear it and repeat some pulls and it pops back up. I searched and saw nothing except a guy with a Kraftwerks kit on his GD. He mentioned it might be car too rich?

Next step is to get a bung installed and get some wideband readings and some dyno action!

 

Have you had your car tuned by Turbogixxer? What was the experience like? Results?

 

Yes, Myself and Portron have used Turbogixxer's etuning service. My experience was great. Kenny was the tuner I worked with, he was very responsive, and went above and beyond to get us up and running. It was a neat experience to see how the processes works, and I learned a lot about fuel injection! Since we are the first ones to run this setup he had to make basemaps from scratch to get us going, then it took about 19 cycles of revisions to get it fully tuned. The results are great, noticeably more & consistent power. The value of this service is tremendous considering the time and expertise you get. Overall the flash tuning is much easier to understand and work with that the piggyback system was, and it is awesome to have people like Kenny to help you out with such a complex task.

Boostedtaco, I don't recall anyone here having that EGR error, assuming that the valve is installed correctly and connected, my first suspicion would be that PnP harness.

 

I was afraid you were going to say that. I'll check the valve and PnP wiring. Anyone have a EGR block off plate and ecu tricker? haha.

A part of me says, i should of went K-tuned and etc....oh well.

 

By design the Sprintex manifold can block of the ERG valve with the addition of some grub screws. There is info in one of the manuals on this. But electronically I don't think there is a solution, other than Ktuner.

 

Oh yeah. But the electronic issue would still be there. I'll probably go k-tuner in the summer once resetting the check engine light become annoying.

I had the mechanic check out the egr wiring, swap in another egr valve and it still trips that code. Even without boost.

Meanwhile, the car is fun. super peppy. I'll go get it dyno'd to check AFR's and maybe fiddle with the tune.

 

My Intake Manifold Gasket just arrived,
so I can compare the diameter of the gasket
vs. Sprintex Intake Manifold Outlet.

It looks like the left and right outlet had more material
to be ported,
while the 2 center one have less material to be ported.

Still undecided which porting service I would use...
will do more research before I decide...

 

Hi Steven,
Do you find out what causing this P0171 error code ?
I am currently experiencing it occasionally now...
I am using Mugen Air Box (come with large K&N filter inside) for a few months never had problem,
and recently I just install custom 2 1/4 exhaust and initially no problem
but recently I got P0171 error code...
I am not sure whether the custom exhaust might have something to do with it or not...
because I worry my custom resonator which sometimes scrapped a speedbump would actually drag the T1R down pipe and causing it to crack on the weld or something like that that create leak before the first O2 sensor, but at the same time I don't hear any noise like a leak down pipe would...
so it might be just related to MAF sensor dirty or loose connection on the intake/vacuum hose somewhere...
but I am curious on how you solve your P0171 error code.

Please advise, Thanks

 

I've just went through a tank of 93 and the gas mileage is umm...less than desirable. haha. How's everybody else's MPG? is K-tuner setup better?

31 mpg with 90%+ highway, average speed of 70 cruise control set, and light boost for merges. Not sure if its due to the EGR check light i get occasionally.

If anyone is going to use the PnP harness, i'd check the vtec and egr wiring. I suspect the EGR is PnP related.

 

Keep up the info guys! Thanks for sharing. This platform has taken for ever to get to this point. Thanks for pioneering and sharing.

 

Does any port-matching need(using this term loosely) to be done between the Fit throttle body and the Sprintex Kit?

 

I think I solve my P0171 error code.
It was cause by the leak on the rubber gasket between the Throttle body and the Mugen AirBox,
due to the tight space, the battery was bumping and pushing the airbox slanted creating a slight leak on the rubber gasket at the inlet of the throttle body.

adjust the mounting and make some custom spacer to the 2 mounting point to further secure the airbox and also tightened the battery holder.
Hopefully this will not happened again
