I just started the install process on my gtu to Turbo conversion on my s5 fc. Well I was sitting there helping my dad w/ all his wiring harness hackery (trying to fit japan spec harness on us car not easy) I started to look at the stickers on the ecu and then looked at the gtu ecu and noticed only the model number sticker so I looked up Redom and found one thing about a boost guage by them in an fd and so I started thinking maybe they make a chip for the ecu and that the Hirano auto technical shop sticker was the shop that installed it. Well here is a pic of it while we were installing all the stuff. Its a cell pic but I think its easily readable.

Oh ya also does anyone know what the relay thing bolted to the side is for?

That link doesnt work for me whats it supposed to be?

redom is a RE-amemiya rom tuned computer. that ecu does have a chip in it but it is hard to say what it was rom tuned for. it could be for just intake, fuel cut defencer, and full exhaust, or it could be for a hi-flow turbo. If that ecu came with your engine then i would suggest running a full exhst and intake on your car. Also maybe take a pic of you engine mainly the turbo area and we can tell you if you have a hi flow turbo or just a stock turbo. If you bought that ecu seperate from your engine then i advise not using it.

somebody5788

well i wouldnt be too surprised if it was a high flow turbo it didnt look normal any obvious things i can look for. I can get a pic but I would like to try and remember so i know sooner otherwise ill have a pic tomorrow the turbo is still out of the car.

oh and the link worked for me but i did not find anything about the redom ecu`s on there.

That's why it's much smarter to use a US-spec ECU and harness, saving yourselves a bunch of unnecessary work...

Here is a Knightsports high flow turbo


then below here are two pics of a stock s5 turbo





There are other versions of hi flow turbo`s. the last one I had in my car was a Garret hi flow I believe made by Panspeed.

Some other hi flow turbos are completely blank. Some other hi flows are custom made and could say anything such as IHI, or kkk etc...

somebody5788

lol ya i know but hey my dad is the expert on this stuff so if anyone could make it work he could. We almost finished the whole harness in like an hour and it only took about an hour and a half to drop the engine and tranny in. Also found out my turbo driveshaft was modded for na diff even though i have the limited slip diff it lets me get it on the road a little sooner jus to try it. Few things I should add the car had performance plug wires on it and appears to have a performance clutch but we didnt have it opened up we just looked through the side and it was bronze in color and had deeper grooves then your average clutch... im gonna go get a pic of my turbo if i can find my key to the shop.

1) Click on the link
2) Click on FC3S
3) Click on the 電子 characters to the left of "Exhaust", then the Redom products will show.

bronze cover means it is most likely an OS giken clutch. Very common on the motors being shipped to the states. Most likely a twin plate, that is a great bonus part especially since that motor has probably seen some hard use seeing as it has a rom tuned ecu and possibly hi flow turbo.

i hate to ask but did you get a compression test done on the motor before you bought it? Engines like that seem like gold until you give a compression test usually.

somebody5788

I did a compression test and got about 100psi for every face. Although I had been scared after some stories when I had already paid for it.







Well thats the turbo not sure if its high flow or not I said it didn tlook normal but i was comparing to other cars stock turbo's which are normally much smaller. The plug wires are nology hot wires and are like 160 a set so i hope there still good.

That is a stock S5 turbo

somebody5788

Ok thanks just seems bigger then your average stock turbo and im comparing to like a mazda 626 w/ a 2.2l and turbo. Is there a way to find out what the ecu was tuned for. Even if I gotta get in there w/ the multimeter and read voltage or impedance to find out thats fine. I would like to put a full exhaust on at some point or just make my own custom one even as I have the tools equipment and the people that can do it lol. If its tuned for intake what are you saying I should add? front mount intercooler? k&n air filter? both? Should I be putting the stock turbo fuel pump or something more?

Circuit Theory

just an open air intake unless your engine did not come with a top mount intercooler then I would suspect it is tuned for front mount also. you should be fine with a stock TII fuel pump.

all you can do is get a real ECU, drive the car with a wideband and record AFR's, then do the same with the chipped ECU.

somebody5788

Well I would do it if I had the donor ecu lol. I have all the tools to do it but not the one dang ecu. Also its not quite running yet still need to source the turbo fuel pump and fuel pump relay and also a downpipe. Also anything I cant remember atm. Does anyone know what the black relay on the right side of the ecu is for I dont have anything to plug into it. Good possability that I didnt get the turbo they got the engine with because it wasnt bolted on and the top mount intercooler was seperate as well.

Circuit Theory

if you have time while sourcing the parts I would compression test the engine again on your own if the shop did it the first time.

The black box is not needed for US cars.

NZConvertible

You don't "tune" for a FMIC. There's no need.

somebody5788

That was the reading from my own compression test but I had been dumb enough to buy it without asking what it got for them. And thanks just wondered why the heck the little thing was there lol.

somebody5788

About the clutch. I looked up the OS giken that someone said it probably had but the clutch didnt look like what i saw there the actualy clutch disc is a bronze color not the cover spring thing and it doesnt appear to have pucks so I assume its like a stage 1 or 2 if its not stock. I did notice that the pedal is very stiff compared to the n/a one is the turbo one just harder or is this more so because of the clutch. Its as hard as my Ford Ranger w/ a 4.0l. Good news though it cranked over and ran for a few seconds w/o mass air flow or vaccume lines or even the turbo connected lol (oil lines were plugged off dont worry). We seem to have messed up the wiring harness though so I am gonna have to get the whole thing i guess. Fortunately I belive I found one for 100 bux just waiting to find out if its for right or left driver. Finally 7 months later and its all coming together I am SIKED. Cant wait till I can really drive it in the spring when the snow is gone. Also any tips of what to do since the lsd I got was poorly packaged and one of the rear loops broke but it wasnt insured and the seller said he wasnt responsible for shipping damage. I have all the pieces and I had sent it to a guy that I trust to weld the loop but he doesnt have anything thats enough to heat the entire loop for a strong weld.

Stage one or two?

What does that mean?

Take a picture and post it yo.

somebody5788

like performance stages 1 and 2 are mild performance clutches where 3 is where the clutch starts to have 4-5 pucks instead of a solid disk. I cant take a pic I never had the engine seperated from the tranny so im going off the little tiny hole i could see through in the side of the tranny.

I think what you're thinking is kinda ricer-ish on that, I was moreso annoyed in my earlier post.

It's just how companies "rate" their clutches. It's nothing to go by when looking at every clutch.

OS Gilken is a twin plate IIRC, it wouldn't be a puck clutch.

somebody5788

Well if the company's rate it that way whats wrong w/ saying it obviously every company is gonna have a differant rating for a similar clutch but thats not the point here. Im just trying to get an idea of what I got with the little info that I have. I tried to get my dad to let me seperate the engine and tranny but he was too determined to just drop it in since he saw plenty of life left on it. It did not appear to be a twin disk or anything but then again I have never seen one installed so I guess I wouldnt know. The clutch material it self was bronze in color thats about all I know for sure.
