I know the injector resizing is handled in the MAF fueling chart, but I'm not sure if that applies to cranking fuel.

If the cranking fuel map was not changed from the original injectors. The engine could be getting almost twice the fuel during start up.

I don't see a cranking fuel trim adjustment so I suppose one could reduce the times in the cranking map its self.

This is just my theory.

 

All working fine now. TurboGixxer had Ktuner add two features to the software, and then sent me a new map and it all works great.

As far as driveability, everything is good so far, getting the rest of the tune fine tweaked now.

 

If I'm understanding this correctly, you're going to run a vacuum hose from one of the ports on the back of the blower to the map sensor?

Same principle as a mechanical boost gauge, which is what I have hooked up to one of the ports in the back.

 

I have a factory map sensor hooked up to a vacuum port on the intake manifold (post blower). I left the factory MAP sensor in the intake elbow so there's not a hole there

 

Yeah, that makes perfect sense. Not the ideal setup, but it will definitely work.

 

Here is my plan, If the threads are the same as the 1/4 adapter the sprintex uses, I plan to use an 3/8 adapter and a bit of 3/8 ID heater hose.

 

The sprintex uses British pipe thread, so you'd need a 1/4 bspt. I've only been able to find them in 90 degree elbows to a barb.

 

Stupid bspt. Thanks for the heads up zf1punk. I ordered a 5pack from McMaster-Carr. So if anybody needs one, PM me.

 

Here is a better looking solution for plugging the old MAP sensor hole:

Here's a video of my Sprintex kit driving around with K-Tuner:

 

Hi Portron,

Thanks for the YouTube Video !

I do have a few questions:
1. May I know which Fuel Pump did you use?

2. Do you remove the restrictor inside the supercharger?

3. Could you please kindly ask TurboGixxer whether an aftermarket Intake alone would help the supercharger make more power?
or
4. Do we need to put larger exhaust pipe combine with the aftermarket intake before the aftermarket intake can help make more power?

5. You might have address this issue, but somehow I missed it,
Did you left the Sprintex 5th injector to cover the holes, or
you have another idea to remove the 5th injector and cover the holes...
If yes, what parts can we use to cover the holes from removing the 5th injector?
and if we just left the 5th injector there, will the 5th injector block some of the air flow?

Thanks

 

1. Evo X pump. It's a direct replacement, just make sure you have the output O ring sitting properly and get ready to swear alot putting the plastic lock ring back on.

2. Restrictor is still in place.

3/4. Well I can already answer this... I'm sure you'll make more power with a more freely flowing exhaust and intake, and you COULD do one at a time, but if you are going to purchase a tune, you are better off having the parts on first, rather then re-purchasing later. I've had my fair share of loud and slammed cars and I don't want to do that to the fit.

5. I took the 5th injector out, used a fuel fitting flange with a bolt in the m middle with loctite on it and then bolted it using the supplied bolts to the intake elbow. I can take a photo later if you want.

 

Hi, Thanks for the information,
When you have time please kindly take photo of that fuel fitting flange,...
even better if you could provide the link on where to buy that fuel fitting flange,
or what type of fuel fitting flange/thread that I need to purchase...
at this moment,
I am collecting parts for the Sprintex Supercharger...

I already bought the cable adapter for the fuel injector from Jackson racing:
https://jacksonracing.com/shop/fuel-...or-connectors/

I used to have K&N typhoon air intake and I am also tired of the loud noise... so I now use CR-Z Airbox with K&N filter inside it...
I hope this CR-Z Airbox will fit with Sprintex supercharger...

I guess the only parts that I don't really know is the fuel fitting flange trick that you use, so I really appreciate your help
Thanks again

 

Looks and sounds great. Kudos to you.

Is everyone running a pretty much stock setup here(engine mod wise, minus the supercharger)?

 

Portron,

Did u get the new piggyback harness for the ECU? did u not use it since u are using Ktuner? also how long did it take u to do the install?

 

It came with the older style harness (bought it used from a member here), and I didn't use the harness at all due to Ktuner.

 

Just saw this on Proreka's Facebook

 

I'm up and running with the Ktuner Flash via Turbogixxer. Starts perfect and drives ok, but there is no power in boost. This might be a very conservative base map? The timing is getting pulled down to the single digits on attempted hard acceleration.

I had a random barometric system failure code, and a SRS light on for a bit but that stuff went away on the second start. It drove fine on the way to work this morning, I just stayed out of boost till Turbogixxer can look at a datalog.

Only thing that bothered me during the conversion was the injector connectors. The pins did not lock into place in the new connector housings. I left it like that for now but would like to find a better solution in the future, besides the SC is so close to the connectors I don't think the pins could physically back out.

For blocking off the 5th injector I did this:



I used 2 shorter bolts and made a gasket out of a bit of hose.

 

Did you get P2227? Bar0? I've gotten this it has something to do with the ECU and Ktuner is working on it. I've sent a couple logs of the ECU doing this.

Also, the basemap will feel slow till he adjusts timing. HUGE difference after he adjusts it.

 

Where did you get block off plate?
