Not sure what kind of knowledge you have with cars/tuning, but if you don't know much about these cars it may be worth getting someone else who does know them to tune it, but if you are from where your location says then, good luck :D

Yes, I am from trinidad and I am not too familar with this car and engine, I've tuned a couple WRXs and I work more on the Dragster's here. I do the electrical, computer and nitrous systems on the Rails. http://www.partytimeracing.20megsfree.com and http://www.mintcars.20megsfree.com.

I need information like the stock timing, if the car has a MAP sensor, the max boost on the stock engine etc. I already did some tuning on the car but I think I have not been able to get the full potential of the engine as yet.

the car has 2 airflow meters from factory,it has a map sensor but its for the gauge only and has no effect on the ecu.....the factory base timing is 15-20 degree's with the bac valve and tps disconnected....as for the link ecu,throw the thing up in the air and run as far away from it as possible before gravity brings it back to earth

There are no mods on the car as yet. The owner was told that the link would be able to faciliate upgrades later-on when he did any modifications. I'm stuck with it right now. I will have to do the best I can with it. It is twin turbo (stock), only 14 psi each (I think). What is the "bac valve"?. Where can I download a manual for this car (in english)?. I may be able to split the MAP sensor and send a signal to the link since it uses TPS and MAP for control. Do you think its better to run the car on TPS control alone?.

...why do you want to fit that useless peice of crap to the car?....

The owner of the car already had it installed in the car. He was duped into buying it. The original installer could not get the car working good, so they brought the car by me. I work on his Dragster so he thinks I can do a better job than the installer. I did manage to get his Idle down and the surging also the trottle response. I still have the boost problem where I need to retard for the boost and map fuel for higher speeds. The car is running rich at the moment but I had to leave it like that because the installer had the link set up for max boost and not incremental. I will have to find out what the installer did and get back to you. I know for a fact that the car is not firing sequential since they set it up for group injector firing, this I also have to fix. Do you have an e-mail address I can write to.

ylwgtr2 knows his stuff so whatever he tells you i'd believe :D

If its a stock RB26, stock turbos, 14psi is on the safe side... if you want a push a little more a lot of people run 1 - 1.1bar on stock turbos... power with stock turbos and stock fuel system will probably net you around 250-280rwkw

throw it out and tell him to put the stocker back in?

or maybe just buy a power FC mate

I contacted one of the tuners at LINK and he told me that they have got 295+HP from the stock R34GTR (at the wheels, without any mods) and with additional mods it can only go up. Then again, I am from Trinidad in the West Indies so I have to take what they say.

as I progress with the tune I will let you guys know. One thing, you can really get addicted to driving the R34GTR.

      Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.

      R33 Fuel Pump & Brakes after alarm swap

      By GTSBoy · Posted

      Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.

      @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html

      These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.

      The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
