Hi all;
I need some opinions from you guys with the utec to see if the utec is right for my applications. The mods on my car (those that matter) are blitz spec R boost controller, rmr hard pipings, rmr induction pipe, rmr intake, rmr downpipe, rmr catback, ultimate racing high flow cat, ultimate racing turbo kit (gt35r), hks 272 cams, hks cam gears, works valvetrain, walboro fuel pump, 720 cc injectors, arp head studs, and the ARC intercooler core (these all will be up and running @ the end of the month). I'm planning to purchase the utec unit as well as turboxs's wideband kit to tune this setup. I would like to hear from you guys to see if the utec is appropriate for this kind of setup, this will be a daily driver, ,that's why I don't want to deal with standalones. The fact that Utec hasn't released firmware to eliminate fuel cut, add injector scaling, rev limiter etc kind of worries me for my kind of setup....so I was planning to revise my current dynoflash to a uflash from Al. Also, would the utec be able to tune out a rough idle? (I'm supposing I'll just add a little fuel) because I am not so sure about the -4/-1 thing silver surfer posted in terms of the performance on a bigger turbo. Thanks for helping me out with this difficult decision.

 

I think the UTEC is perfect for what you are doing. With the UTEC you can do a hi and low boost setting and also a race map. this is good since this is your daily driver. It also allows you to change settings if you ever add anything or for weather changes. I think you would get a good benifit out of using the UTEC plus its simple and a one time fee. Also the tuner would work well for you. But I would put that thing on a dyno and tune it first and then fine tune it on the road.

 

I'm not looking to make maximum power available, I'm on 91 oct most the times heh. But I really want to make sure the idea of getting a uflash from dynoflash to take care of the inadequecies of the utec first is a good idea or not.....also, I won't be dyno tuning the thing most likely, because like I said, I'm not interested in max power. I probably will be road tuning the thing.

 

Well, It can't hurt if you want to "hard code" your injector scaling and raise the RPM limiter and fuel cut.. But these features will be released shortly built into the UTEC.. the only real advantage of having the scaling done through a flash is you can remove the UTEC and the car will still run fairly normally.

Your in a similar situation to where I find myself.. I want to tune my car with all my mods installed.. But I'm waiting (and tuning wtih minimal modifications on my car at the moment) until the new flash is released.. I do not currently intend to use the UFlash though unless its absolutely necessary.

I do however intend to use the boost control built into the UTEC to control any aftermarket turbo setup I end up with.

You really can't go wrong with the UTEC.. it has the power of a standalone with the simple install and setup of a piggyback.. plus standalones could be an issue with inspections (OBD-II Check) For the combo your running you really have three options, an ECU Flash on a dyno, a full standalone, or the UTEC (or XEDE)

My personal opinion is the UTEC does everything I wanted and had no proprietary software, or required a professional tuner to set up my car, and it can be changed at any time.

 

sounds like I'm making the right choice. =) I'm just scared if I did the uflash, then when the new firmware comes out, it might mess things up with tuning a modified ecu......I just dun want to go through the trouble of flashing the thing back to stock later is all.....

Well looks like I will be joining you guys on the utec, I called turbo xs and theres good news (at least I think it is). Seems that the new firmware will be released by the end of the month. =D

 

i currently have been dynoflashed on the dyno and I am thinking of buying the utec with my next rounds of mods, 272 cams, injectors, FMIC and piping, and I was planning on having Pruven tune it. If i decide to get the UTEC, do I have to have my ECU flashed back to stock

 

No, you don't have to flash the ECU back to stock.. However keep in mind that if you don't, all tuning that you do will be on top of what is already in the ECU, therefore you will not be able to use suggestions or maps from other tuners/users.

If the dynoflash works for you, you don't have to flash it back to stock. However the main advantage of using a dynoflash *AND* a UTEC is you can remove the UTEC if needed and the car will still run decently (if your flash encompassed upgraded injectors and fuel pump)

In theory, you could ask Al to reflash your ECU with his UTEC flash, and injector scaling parameters if you find you need them and cannot wait for the features to become available on the UTEC (Fuel cut, RPM limit changes, and Fuel Injector Scaling)

Again, theirs nothing wrong with using both a Flash and the Utec.. but tuning will be a bit different than someone with a stock ECU.

FWIW, my car with just an exhaust and filter upgrade made over 300whp tuned with the UTEC only, and only with the fuel settings, Its likely with timing adjustments I could do even better.. without a flash or anything more difficult than a few road tune runs and a wideband o2 sensor.. so make your decisions on facts, choose what works best for you.

 

John,

Theres one on ebay right now for cheap, plus one guy on the boards selling one for cheap with a brand new Tuner, might want to pick those up and give me a call. I can help you tune that setup pretty quickly on the street.

 

Actually Braden, as usual, I already bought both the tuner and the utec from z1 =) My usual vendor......heh. So Everything is comin in and I'm just waiting for it to all get here so I can piece it together....

 

Excellent! Give me a buzz when its all in!
