Soon I plan on going FI. This is not a dreamer thread, so you can continue lol. I plan on purchasing the Boosted Performance turbo kit in the next couple of months and Im not real sure what tuning hardware/software I should use. My goals on a stock block are not real high, just whatever ~6psi gets me. However down the road I would like to do a minor engine rebuild and get around 450whp. Again not a real high goal. My only question is with a power goal like that would it be overkill to get a full standalone such as Haltech? Would it be more sensible (Im not trying to be cheap by any means) to use Uprev or Turbo XS? I dont want to go spend an extra few hundred dollars on the Haltech if it doesnt provide any benefit over the others at that power. Sorry for the noob question and thanks in advance.

 

At those power levels id get the uprev and save some money ..you dont need everything the haltech offers for your goals

 

Fukc Uprev get the HALTECH and blow that bish up!!! J/K

Seriously man its up to u but I myself am in the process of pullin the trigger on my BP kit and Its jus not complete witout the Haltech... I figured if I wanna upgrade which is inevitable Ill have the ems to support all of my build. Its better to spend a little more now then to find urself tryin to sell a used utec or uprev to fund the standalone later and thats jus my opinion,,, Good luck in whichever route u take

 

I say uprev. Haltech is overdone on builds with 600whp or less.

 

If I were going to stay within the limit of the stock MAF (6 psi is about there), then I would go with UpRev. Having Osiris tuner is very nice, no matter what, so it's a good investment. When you move on to MAP based tuning, upgrade to the Haltech - and the Osiris purchase will still be worth it's weight in gold (for diagnostics, disabling CELs, setting DBW parameters, etc).

 

^ you an also get the HPX maf so you can tune past 6psi with the uprev.

 

Even with the HPX there is very low resolution for tuning within boost. MAF is terrible for high boost tuning but acceptable for <8psi.

 

I love my utec but I have a supercharger.

 

get the haltech. You can alway pick one up used. Like 350zion said, it will save you money in the long run. If you decide to upgrade

 

my 1st question to u is.. "who my tuner is gonna be" and what is his capabilities...

 

I'm going to have to disagree. A MAF system will work just fine at high boost if the time is taken to properly set it up.

Sensor placement must be considered, as its proximity to piping diameter changes and bends can effect the MAF's ability to measure airflow. Airflow measuring limits must also be considered along with cross sectional area of the pipe or housing the sensor is installed in. Time is also required to set up the MAF table properly. Either system (mass air, speed density) will get the ECU the necissary load value to run the engine, however, mass air takes a bit more to get set up properly if you're starting from scratch.

Another thing to consider is will the hardware be available in the future, I seem to remember seeing somewhere that HPX MAFs were no longer available.

I run 20psi on an HPX MAF and UpRev, well past the goals set by the OP. The car never misses a beat. I would recommend the UpRev for his setup, but more options can be had with the higher end systems out there.

My other vehicle runs 52psi of boost on a MAF system, and also runs great.

 

They were for a while, they've got a new supplier lined up now tho so availability shouldn't be an issue in the future.

I'm also running Osiris w/ an HPX maf @ 16psi, hasn't missed a beat

 

Although you have a point that MAF is OK for boost tuning, I should rephrase my comment being more specific to Uprev in general. There's no way Uprev has anywhere near the resolution as a standalone running off MAP at any boost level. I mean seriously you've got 16x16 and 4-6 columns are dedicated to vacuum. That leaves about 8 columns for boost assuming you don't want to max out your maps 100%. Even a UTEC has more tuning resolution in boost.

 

I agree that the stock ECU doesn't have much resolution...but it's really not necessary for a daily driven vehicle that's tuned to be safe ( slightly on the rich side with timing not so high ). For a race car however, where every single whp counts, I would run Stand Alone hands down.

 

I can't disagree with the 16x16 map, but I've never had an issue that led me to believe I needed more resolution.

Also you can rescale the load to move resolution where you need it. I use 4 colums in vacuum, 3 for boost to 10psi, and then spread it out a bit above there using 8 colums for the BSF in the 10-22psi range, the last column (2nd and 3rd to last column depending on the RPM/BSF dynamic) has low timing numbers as a type of overboost limit, or at least something that is going to let me feel something is wrong and let out.

Honestly, with it set like that, it's adequate resolution over 10psi of boost, I could probably shrink it down to 5 and be perfectly fine with no noticeable change in drivability.

Again, I'm not disagreeing that the other options have more features and abilities, I just don't see them being needed until 600+ WHP range, and even then, not absolutely necissary. Now when I get some bigger injectors and fill this turd with E85, we'll see how far it will go, or my engine.

 

Thanks for all of the replies guys. I might be leaning to uprev. From what I have read I dont think that I would have much more benefit over uprev with the haltech. Im still going to do some more research to see what would be best suited for my needs.
