Default will a utec work with 4eat?

i just bought a utec off of a private seller at a really good price but after talking with someone at turboxs i am skeptical about using it. Even the guy at turboxs said that i should just get a reflash. do any of the other 4eat owners have a utec running in there cars?

I am going to do a 5 speed tranny swap as soon as i get the money but it is going to be a good month or two. i have considered a pt tc but what horsepower i want from the car i am not sure the 4eat can handle.(400 whp give or take).

IIRC the newer UTECs have OL/CL fuel flexibility that is incompatible with the 4EAT -- I think there was a workaround (e.g., you can't use the OL fueling feature, etc.) but I have a reflash so don't really know. There are a number of people running UTECs over reflashes (Rifts for example) and someone -- forget who -- is running a UTEC w/o the fueling feature on a 4EAT. So... I don't really know the answer but there are people out there who will. Search for "4EAT UTEC" too.

A lot of work from what I have seen. What about just trading the car in?

By "can handle" what do you mean? If you mean "can handle with a stock 4EAT" well no, but the same goes for a 5MT. If you mean "can handle with an IPT tranny" then -- though I have not spoken with Jon @ IPT on your question -- I would say it could probalby handle the power better than a MT (though talk to the experts on this, e.g., www.importperformancetransmissions.com).

The 4EAT robs some power from the wheels, but it's not weak. The fastest WRX in the world is a 4EAT (though now significantly modified).

i thought about it and a dealer will only give me 11k for my car and there is no way that i am going to trade it in for that.

with the tranny swap i expect to spend around 2k but tthis is with some upgraded parts(clutch) then i will save for the gears, but dont know which ones yet the dogbox from turboxs looks good but so does the ra gear set. i will do more research before i decide

hopefully the install will go smooth but nothing ever does. the only thing that i have to actually drill is for the pedal set all of the other locations have the holes in the firewall.

You can run a utec on a 4eat, you just can't run the olf feature. I have had a utec on my car for 3 years now with a 4eat and only have a few minor hiccups. For a normal everyday kind of thing you would never notice them. There are a number of people on here that have utec's with the 4eat. If you are looking to do some tuning the utec will work, if you are looking for a set it and forget kinda of thing, go with the reflash. Just remember that with the utec you can not run olf, so your fuel map will look a little weird.

Dude... you just lock it in 2nd gear. Take the shift level, and move it to the "2" on the gate. It stays in 2, wont move to 1 or 3. "3" will downshift to 1 or 2, but "1" and "2" will stay locked in that gear.

And I get my tuning done on a dyno dynamics that way, by the way.

stay away from the utec, especially if you're going to push a lot of horsepower.

A: I told you when you first got that tranny in not to run OLF, you refused.

B: It's 130MPH

C: well no arguement on the support side.. but lots of projects, one Pete.

I have a utec and have hit 145+mph. Does it not remove the speed limiter only on the auto's?

A. so what? i used OLF and it broke, hence my advice not to use the UTEC with a 4eat. whether it was my decision or somebody else's to use OLF is irrelevant. the fact is, the UTEC's OLF did it, so it's a bad idea to use a utec with a 4eat.

B. it's 120mph. i have never been able to go over 120mph. http://forums.nasioc.com/forums/show...+speed+limiter

C. meh, don't blame them. i know of 2 people using (or were using) UTECs with their 4eat. you and me. i doubt they come out with a revision just for the both of us.

I do have a manual. I'm buying the parts from you to convert to auto. Its been a while, but I'm 99% sure that the speed limiter is on the manual too. I took the babied break in approach, and after 5000 miles, I ordered a UTEC. Waited for like two freakin months for it back in the day. Installed the UTEC, headers, catless UP, catless TBE, and CAI all at the same time. So I may not have ever attempted over 120 before then, but I'm pretty sure I did. If I remember correctly it was a fuel cut at 120mph, and cutting the wire was the common mod at the time.

You know nothing about what I know, or my automotive background so suck it n00b.


You clearly admit your OWN STUPIDITY is what broke it. You WERE TOLD THAT YOU CANNOT SAFELY RUN OLF, and yet your dumb ass ran it, because you obviously know more than EVERYONE ELSE, then you have the sheer balls to blame the UTEC for YOUR OWN FAILURE TO FOLLOW SIMPLE DIRECTIONS>

A: Jason... a LOT of my customers with 4EAT's use UTEC's in CLF just fine.... It just take a LOT more effort to get fueling right, but once it's set, it's set and works quite well.

B: It's the factory speed limiter, which Subaru claims is 130MPH, if you hit 120, then I suspect your speedo gear is off.

C: I can rattle over a dozen off the top of my head, and I know I've done more.

the speed limiter only applies to the auto. the utec will work fine with a manual. this is a thread about the utec with an auto.

hey retard, the trans slipped even when it was on CLF. it broke a race prepped auto trans on OLF. see, you're only stuck on theories and instruction manuals, while i already went thru it and paid for it. stick to reading the intraw3b. n00b.

question is...how much power are they pushing. in case you don't recall, my vb was already slipping long before i went into OLF. remember when we were on I-55, and when i punched it and the car went, "WHAM!" and then you said, "What was that?" and i said, "the trans." and then you asked, "have you done the vb mod yet?" "nope." "it's time you get it done at this power level." and so for the rest of the tuning night, we were downshifting to 3rd.

a lot of auto people i know cannot go past 120 either. so if it is indeed 130mph, then they must have put some flimsy speed sensors o the autos.
