The Vert ECUs are a little bit different, i'm trying to find the Code for it. Mine is actually reman from Mazda (was in the car when i got it) the main difference that i can tell is that i have a working knock sensor that the ECU takes into account.

 

wait so you have a knock sensor on your N/a block?

 

Umm, I hear the only NA ECU that recognizes boost was the 88 vert...none other.
I would love for this to be incorrect because I have an 89 vert..
Anybody else want to shed light on this?

 

Yes, didn't realize it until I plugged in my SAFC-II and noticed the knock sensor wire was there, and even more surprised that it worked.

And According to www.rotaryressurection.com any Vert ECU should work as long as it's the same year.

 

There was a whole thread about the 'vert ECU a while back.

I just searched for "vert ECU":

Thanks Aaron i'll be looking into those threads.

 

hmm it appears i'm out of luck for boost compensation in my 89. God I hate S5's.

 

so chaange the ecu and pressure sensor.

 

Bah! I shall run the T2 engine with the high compression rotors on the stock Vert ECU with an SAFC and larger injectors and better fuel pump. I'll find out for certain!!

It's just a few months away...lol...

 

yeah itll defienetly work. Just safely and how long, are the questions. Why not just run the turbo ecu though, thats what its meant for.

 

With proper tuning it doesn't matter almost. There was a guy with an all out race car running 20B peripheral port with 10:1 comp renesis rotors and a huge turbo. Proper tuning makes a lot possible.

 

I'll probably get one eventually.

 

OK..in defense of the S5 6 port turbo people, I will chime in.

I have a S5 (9.7:1) 6 Port Turbo (91 Vert). I have used the stock ecu (N353), the turbo ECU (N370) and an EMS. I am using the stock Throttle body and intake manifold. The exhaust manifold is from a FD as I am runing a T 62. The pressure sensor was from a T2 (N370). I started with 6 PSI and I am up to 10 PSI. This will keep it safe as it will spike to 12 PSI.
For those of you who are wondering how fast....... 5.0 for breakfast, WS6 or Camaro SS for lunch..... and I am still looking for dinner (vette). Maybe afterward I will try desert (wsx, evo). I have to take it easy...the car has only 140 miles since rebuilt.

do u have HP numbers?



i wanna turbo my s5 : )

 

I am running a TII motor with s4 NA rotors. I started get detonation at 15 psi with the stock IC and a poorly tuned microtech. I run 8 psi normally, on 89 octane, with the stock IC.

During xmas break, i will be upgrading turbos and installing a fmic, as well as taking the car to a dyno and having it properly tuned. after that i hope to run 12 psi.

on i side note, i ran the car on the stock ecu at 8psi on 87 octane for about 8k miles with NO problems whatsoever.

I dont have much experience with s5s, but i think that with the lighter (thinner) rotors and the higher compression, not much boost would be possible.

pat

 

Let's see some numbers on this "beast" So you're running a rebuild with 140 miles, and running low-mid 12s? That's what, 375-400 HP?

 

I would also like to hear from some s5 turbo'd 6 port guys, cuz I am thinking about it but with most of them blowing the motor, I want to hear some success stories.

 

Agreed... I hear some people don't break in their motors lighty, but jesus getting into low boost after only 140 miles?

People have more ***** then i do.. i put almost 1600 miles on my rebuild before i even thought about pushing the pedal (well.. i thought about it....)

Guess I'm the craziest.

21psi BNR Stage 3 Hybrid
Stock (s4) N/A ECU
S-AFC
550 pri 1000cc secondaries

Don't ask for the timeslip, because I refuse to post it. Btw, I could beat half those cars listed in N/A form, let alone when I turbo'd it.

 

Thats a lot of fuel

 

Craziest...oh wow..SonicRat haha you are like a God..damn, I have thought about it for the longest on trying a T2 lowerintake and upperintake manifold, and port matching..but I just am still not sure..b/c I would like to keep it runnin good and for along time, but I guess thats where a EMS comes into play.....who knows I will more then likely go for it here soon..

 

 

21lbs on pump gas is sick. But they always say "he who has the biggest ***** and pockets wins".

 

me wants a stage 3 now!!! ANy god advice on where to get one for a good deal, I blew my turbo after about 2 weeks, bad bearings
