Ok as few of you know my split second box is crap & i feel like taking a bat to it. So im changing my plan of the car. Im selling my wheels & tires and the hood. And I am goin to be getting......

Utec w/ remote & map sensor

440cc injecters

3.12 vortech pulley

Recallibrate Vortech FMU

install & dyno tune @ SGP in houston.


So hope all this will get started in a week or two and I will finally have my 400 hp beast. If yall have any comments or knowledge to throw at me feel free.

 

the vortech supercharger didn't give you new injectors? weird. I hope they gave you at least an intercooler lol.

 

Yeah the kit comes w/ an intercooler just no injectors. I should have just gotten the tuner kit and done this from the start.

 

+1

ditch the vortech fmu and get a walbro..u can scale the injectors with the Utec

 

I got the 255 walbro fuel pump, are you saying that i wouldnt need that anymore?

 

The Vortech FMU is controlled by the SS Box and it's a secondary fuel regulator in addition to your stock pump that increases fuel pressure based on boost. It's basically overworking your stock regulator. If you have the walbro, and you're getting the Utec, you don't need the Vortech FMU or SS Box.

 

But if i am to get a new ss box then i would stick w/ the fmu. Utecs install price is a little hi for me. So either the shop that tried to tune it didn't know what they were doing or the box was just bad.

 

If you're going to stick with the Vortech FMU, then don't use the walbro...most people also cannot scale injectors with the SS box...you would need a reflash from Technosquare to scale the injectors...imo, you're better off with the Utec and walbro...if not, you can use the Greddy Emanage Ultimate...that's what I used.

where's booger or sentry when you need them? lol

 

yeah i don't know what else to add. I didn't have the SS box, I had the emanage ultimate and didn't enjoy the experience with it - bad starts, fried coils, buggy software, etc

An ECU flash for a vortech kit will get you in the ballpark where you need to be and properly scale the injectors, then you can use the SS box to fine tune everything. A cheaper solution but with less control would be an ECU flash and SAFCII for fuel tuning

I'm moving to an Fcon V-pro and will be selling my SAFCII soon hopefully for something like $200 or so if you'd be willing to wait 3 or so weeks

 

If i were to get AAM reflash then take it to get tuned w/ the ss box your saying that they should be able to tune the injectors better. and still keeping the larger fuel pump.

Sentry would i use the SAFCII with the SS box or would i just remove it.

 

the AAM or technosquare flash would give you a new baseline A/F curve and timing map. It would also scale your injectors and raise your idle if you wanted (I'd go to around 1000 rpms)

on top of that, you could run either the SS box or the SAFCII

the SS box can adjust timing and A/F

the SAFCII can only adjust A/F but costs less. The advantage it might have over the SS box is it has something like 48 (I think) points that are adjustable in the rpm range and you can move each point to any rpm you choose in 50 rpm increments. The SS box on the other hand can only make adjustments every 500 rpms which is quite limiting. I opted for the SAFCII over a SS box because I thought it would be the lesser evil and just used AAM's raw timing map on their ECU flash

So far, I've been happy with AAM's timing map as far as being a safe timing map

 

So if i have already gotten the car tuned ( not a good one) and then got the aam reflash would it still run right before i were to take it to houston. I am assuming I would also need to have the 440cc injectors and 3.12 pulley and fmu recalibration installed before i put back in the ECU since thats what its tuned for, correct?

 

why not just ditch the fmu and just get the aam stage 1 fuel setup? I'm always afraid that the fmu will stick and get stuck and BAM..... bye bye engine.

 

You know what Im glad you pointed that basic kit out. That would be perfect for my setup, never knew they had that basic kit. Thanks for the find. Now how hard would it be to install that bad boy. They say 6-7 hrs would this be something I could do w/ basic mechanic skills or leave it to a shop?

 

you can get the AAM flash and run that just fine with the SS box on your trip but only as long as you DO NOT give the car much throttle - absolutely stay out of positive boost and really stay less than 50% throttle and don't go above 3000 rpms, and you'll be just fine making your way to the shop to get tuned via the SS box - which will have to have a totally different tune. It'd be more of a fine tuning than a drastic tune

if you get on the throttle at all, the car will run excessively rich and you can either burn out your cats or possibly harm a sensor (not so likely though) or possibly destroy the inside of a muffler or something. So you'd just have to baby the car there and keep it at an easy going cruise


I'd think SGP could tune the SS box pretty well though. Seems like several people have run the 440 injectors with the SS box, but I dunno for sure. If you can run off the SS box alone, that's probably the simplest solution.
