Hey guys,

After a chat with a mate regarding tunes etc, just want to klnow what others have done!

Ok, so you have done the basic mods - exhaust, fmic and added a bit of boost with cold air/filter.

Now - have most of you guys left as is or decided to play it safe and go a tune to make sure all the AFR are right and such n such and making sure its not running rich or lean when boost comes on?

Because so far i have just done the basic mods as said earlier - and it got me thinking, am I going to destroy my motor later on by not tuning it for safety not just out right power?

Im not that smart with turbo motors and boost - my experience has been with LS1 motors!

or am I just being paranoid???

Cheers,

Chris

there are also things that you can do before you get a dyno done to help richen up the afrs (but results vary). first of all is to clean the afm. if its dirty then it isn't reading the correct amount of air and can make the car run lean. you can also check the fuel pressure. it is better to clean the afm before the dyno run, as you don't know if it will have any affect and then atleast you can see what they are like when its clean and if it is still lean thats 1 thing that you can cross off the list.

Hey Chris

Provided you don't do anything too silly, like run 30 psi or something, just the standard mild mods on stock turbo won'nt destroy your car, it just won't drive much better than stock, that's all.

On my car, i've done everything but the ecu, and i get big rich and retard. When that kicks in, it feels like I get pulled back. there's a big dip in power. so It doens't feel, nor is it actually very quick.

I reckon either do all the mods + tune, or just leave it stockish

nah im not that silly :thumbsup:

basiclly its on 7psi 90% of the time and then if i feel like it switch it to 11psi

Im just thinking now - perhaps I should get a tune to keep the motor safe - however buying a powerFC and tuning just for basic mods - is it worth it?

I dont know!!!

For the 2k you spend on the PFC and tune mate the car will run better and smoother, and thats with more power and being more fuel efficient too!! I'd say go for it, i plan to. :huh:

can you remap an r33 ecu?

i thought it was just r32s?

i'm not sure if anyone is australia does it. i have been told a place in brisbane does it. i have a remapped 33 ecu that was done in japan.

if you are only running at 7psi and occasionally 11psi then you could go the cheaper option of a safc2. it will make a noticable difference.

It won't really make it 'safer' because it's not really at much of a danger as it is. If anything, the benefit is in fuel economy and performance. It will make it have more power basiaclly all over the power range.

If you're going to do it though, i'd make sur ethat you do every mod you'd consider, so you don't waste money on a tune again later.

e.g. fmic, full exhaust, turbo if you want, camgears, etc.

Instead of an safc, take a look at the jaycar one. it is basically an safc in a cheap looking box at about 1/5 the price.

Chris, I know OF a guy that can remap r33 ecus. I have nothing to do with him, he just posts up on here occassionally. I'm actually saving up for a remap myself just to see how it goes. From memory, last time he posted, it was 350$.

the jaycar safc will be around $100. then the tune will be like $300. SAFC only allows adjustment of fuel, not ignition.

I reckon the remap for 350 is seriously a pretty good option. Fuel, ignition map changes. Removal of speed limit. you still retain all the good stock ecu stuff like cold start, consult etc.

thanks for the info mate!

Yeah I knowe the general rule of do all your mods - then get it tuned to suit. however I feel that this is all I want to do as now I want to get the suspension set up for some track/hillclimb work and eliminate that bodyroll! :P

cool - if you like could you pm me this guys name?

Wouldnt mind getting in contct with him!

cheers!!

Chris!

in order to tune R33 on dyno, board is needed, which approximately costs $350-$400 only board.

Tuner makes ECU map on dyno themselves and this data is transfered onto PLCC chip then fitted onto the customers ECU

Other wise use R32 ECU ( need change all map.not only fuel and ignition).

R33 chip is selling at http://www.grid.co.jp/en/prod/prod93.htm.

This is a one time chip.

when remapping ignition timing DIY, make E F colum same as D colum ignition timing. ( also remove speed and boost limitter)

This means about same AFC.

And adjust base ignition timing by crank angle sensor about 2-3 degrees.

There is no need for a fuel map change.

Because when fitting dump pipe and hi flow cat , cat back, air pod , boost 0.8-0.9 bar A/F changes to about 11. (depends on parts performance)

A/F 11 is not rich. HKS kansai drag racer GTR A/F11 for safe and power.

I think rechip is cheaper way ecu tune for std turbo R33 GTS-T.(my map is totally different std map).

If change turbo in the future I recomend power fc for R33.

I think R32 do not need power fc.

If some one having pomping or fuel rich problem please send me PM or [email protected].

I be able to chack problem by softwear then I will fix it. ( NSW only)

Basically a lot of mucking around and will be hard to find someone in your area to do it.

      Unpeeling the Orange

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
