Those Who Have Tunes And Havent...

[evil_weevil]

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

You can get your AFR's checked on a dyno then decide weather to buy a aftermarket ECU. As I explain in my tuning guides after these mods your car will probably be running rich plenty more power can be had with a aftermarket ECU or SAFC

cheers

i put my mods on, zorst, fmic and pod etc...

found out my car was funning lean as, 14.1 afrs

got a dyno run to find this out

got an ecu remap and new fuel pump, afrs now 12ish

definatley get it dynoed and checked out

[evil_weevil]

I guess thats right - I dont want to do a track day or something coming up and have my motor all lean and risk engine drama's!

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.

I wasnt going to go to town on this car so the re-mapping of the factory ECU might be my only option.

[JVP]

can you remap an r33 ecu?

i thought it was just r32s?

[evil_weevil]

oh wouldnt know - see Im new to all this well...Ive owned the car since nov 05 and still dont know too much

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

[JVP]

theres no point in modifying it and then not tuning it to suit.

[evil_weevil]

nah im not that silly

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.

[mad082]

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.

[evil_weevil]

safc2 sounds the go - might have to do a bit of research

links anyone heheheh

[MANWHORE]

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$.

[MANWHORE]

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!

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

Wouldnt mind getting in contct with him!

cheers!!

Chris!

very interested in this $350 tune for a R33 also never heard of anyone how can do this yet

[Munna1]

posted by toshi in an old post

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.
