I have a 97' prelude SH turbo by the end of the week.
I am having my car switched over to an obd1 p28 ecu.
can anyone tell me if I am still going to have my ATTS intact
or how I can get it back if it does not work.

 

to be more specific its running 7psi on a custom kit with stock internals.
I am hoping to get atleast 280-300 WHP

 

If you're boosting- get rid of the ATTS, or it'll get rid of itself .

300whp on 7psi?.............thats a pretty decent size turbo.

Oh, and your atts won't last a day with 300whp.

 

so can I just pull the fuse? and will the atts light come on?

 

hahaha.

You have to get rid of the entire system period.

 

thats weird because ive heard of people just pulling the fuse and it runs fine.
but you might be right. i hope that doesnt mean pulling the tranny

 

the turbo is a t3/t4, also how good do you think that the car will run as a weekend car or a few days a week. I know that my car runs around 4000rpm on the highway and that it will be at full boost so i hope it can go for long road trips

 

Are you having someone do it for you? Give more details on the setup...

 

You don't need to disengage the whole unit, just disconnect the fuse. With the fuse disconnected, power to the unit will be cut-off, and the ATTS unit will be just dead weight.

By the way, your ATTS feature will not stay enabled if you are putting down around 300 horsepower. The bands in it will start to slip and it will disable itself.

No you don't..

Like Dirtysouthbb6 said, it will be fine with the fuse pulled and the p28 won't be able to control it anyway even if you left the fuse in. To answer your original question, there is no way to keep atts working unless you were to use some kind of piggy-back (SAFC, e-manage, FMU, etc.. not recommended) instead of a real ems - keep your p28.

I am having a local tuning shop do the work (TDC Tuning Concord, NH)
its a t3/t4 turbo kit with a custom 3'' thick intercooler and down pipes, HKS SS BOV, a true 3'' thermal exhaust from the turbo back, p28 ubberdata chipped ECU
and precision 550cc injectors to take care of the fuel.
I am very curious as to how this car is going to run. (I am getting it on friday)

 

If anyone has had a similar setup or knows someone that does, please let me know. I have never driven or owned a Honda with a turbo, so please give me details of what I can expect.

 

Hmm, dont mean to sound like a pessimist, but 300whp on an h22 with stock internals isnt going to last all that long. That is, unless, it's properly broken in and tuned correctly. Good luck on your setup.

 

Sorry. My fault. I was under the impression the entire thing had to be removed. I read a couple times that people where switching the transaxles.

 

also, this will not be a drag car, but what can I plan on running in the quarter mile
if I decide to go once or twice. I hope I can take an SRT4 (some of my friends have them)

With 300whp, you can expect no traction in the first couple gears, but it should be a screamer on the highway. If you're a decent driver, you could probably do mid 13's in the 1/4 mile and should be able to handle an srt4.

I'd also have to agree with Hank, 300whp on a stock h22 is a little scary even with good tuning. I wouldn't try to do any extended 5th gear pulls if it were mine unless your looking for a reason to rebuild your motor

Good luck

 

:takes deep breath:

Let me spit some knowledge-
you should look for about 260whp on 7psi, maybe even less with your turbo. you say it's a t3/t4........that only tells half the story. what kind of t3/t4. mine is a precision sc61, a t3/t4 that can handle 680whp. then there are t3/t4's that come with some turbo kits that can handle about 300whp. that's a BIG difference. A/R ratios are a big factor there. so if someone asks you what kind of turbo you have, saying "it's a t3/t4" will only embarass yourself. I'm going to guess that you have a smaller t3 turbo, maybe with a .49 or .56 a/r that is good to around 450whp. that is not going to be enough turbo to make 300whp @ 7psi. at least not without running it pretty lean, which you don't want to do.

your atts WILL NOT work with a different ecu, and even if it would, the unit would disable itself once you realized you were raping it in the *** with no lube.

You don't want to make 300whp- not without building the motor first man. that thing will tear apart. you could do it, but not make it last as your everyday driver. you really need to make sure your compression is consistent across all of your cylinders before you even think about going turbo. if it's not, then boosting it will only magnify your compression problems, and eventually destroy your ringlands on your pistons. like i said, look for about 250-260whp at 7psi. it should be enough to take a stock srt-4, or at least hang tight with him.

The tune is the most important factor that will decide how long this motor will last you. make sure this guy that is tuning is very reputable and knows what he is doing with uberdata, if that's what you are using.

By the way, when you are at 4000 rpms on the highway, that doesn't mean you are at full boost. actually, you are probably in vacuum unless you are on the throttle. it's not going to make a difference in your long trips.....in fact, you will probably get better gas mileage on long trips due to the turbo making your engine more efficient. so don't worry about that.

Oh yea- If you want some bigger injectors.....i've got some 680's for $200 shipped.

OK, i'm tired of typing now......hope what i said is useful.

I appreciate the usefull info.
As far as I know the turbo is the sc61 which can handle crazy power.
The guy who is doing the tuning actually invented/came up with the UBERDATA
program. His name is Jon Drenas, so for the tuning aspect of it I am not concerned. I spoke to him about the ATTS and he told me it is on a seperate computer, and he has seen the ATTS handle alot more power. He expects to make anywhere from 270-300 WHP so you could be correct there. Just giving you a heads up. Thanks
