Hi All,

Just got my 1999 RSFour Auto dynoed and it put out 100awkw...

Its pretty stock with the exception of a 3" turbo back exhaust, Hiflow panel filter, Profec B set at 13psi....

Does this seem a little low?? I got it done at tunehouse (ill post up the dyno printout when i can) and supposedly it was done in 4th gear...??

What do you guys think, Is this a reasonable result with the mods done??

cheers, adrian

If you still have the stock ecu, as soon as you up the boost, esp 13psi they go into rich and retard. So they dump in heaps of fuel and retard timing equals no power gain

I would drop the boost back to 10psi until you can get some sort of ecu control. It will probably make the same if not more power.

yeah i'd be walking away from that quote. look for something in the $800-$850 range, that is a more acceptable price for supply, install, and tune.

EFI do a sau club price of $990 supply and install and tune.

Since we are talking about a "auto" stagea that price will not apply. Will have to use a z32 ecu and it will need to rewired as the plug to ecu is different. $1500 is sounding cheap to me.

My tuning. not as staight forward as a fairly stock car, has cost $900-1000 already and still needs another 2-3 hours x $180hr

that only applies to s1 mate

if its an auto s2 its the same board as the manuals cos the nistunes just contain the new fuel and ignition maps

Planning to order the chip from nistune directly (anybody here installed themselves...? Does the type 4 board require soldering?) and take it to a workshop to get dynotuned..

Can anybody recommend a Sydney workshop to dynotune a Nistune??

Cheers,

Adrian

yes it does require soldering your better off getting someone that has done them before to install the board dont think it is a do it yourself.$800.00 to $850.00 drive in drive out with they bit of luck they have the boards so you dont have to order them or send your ecu to nistune in S.A and they will do it and send it back then all you need is someone that can tune it

apparently unigroup or somthing like that in sydney are the ppl to go to

the guy there is apparently a wizard at powerfc's and just about anything

and to put the nistune in needs a proper de-soldering gun because you have to remove some solder from the board, put the nistune in and solder it back up and it can be tricky to get it out without heating the board up too much and its tricky to get it out in one go (which you pretty much have to do)

Yeah it can be a bit tricky to get the EPROM out without damaging the board. I isntalled a Nistune board once. Didn't take that long. Just needed a lot of hot air to get the chip out and then solder wick to clean up the left over solder.

just got stagea back from horse power in a box. got the nistune chip done and made 200 rwkw (front shaft removed) not bad considering the boost drops from 12 psi to 9 high up in the rev range. and all ive done to the car is a fmic, pod filter and replaced the rear muffler with a straight pipe. $1200 worth of mods well spent now need to save for that 3076 and other supporting bits

Good return! I am sure you will find car feels quite zippy with 200kw v stock!

oah shit yeah, major differance. feels great when it comes on boost, just wish it would hold it all way through

ebay - turbotech boost controller

its the best manual boost controller out there and should help you keep the same psi to redline

Can someone please tell me about this nistune piggy back computer, i havent been around the forums for a while and have lost a bit of touch with whats good and whats not for stag's, where can i get it from? where in melbourne is good to get it tuned and whatever else i might need to know about it would be much appreciated.

Cheers Simon

I finally got around to putting my results up...

Intake mods: Custom powerduct, K+N filter, 80mm intake, stage 1 Sierra highflow bushed turbo, cut down Greddy intercooler, 600 x 220 x 76, with custom piping.

Cam's denso plugs, still not breaking down at 1.1mm.

Custom 3.5 inch dump into highflow cat then 3 inch to quiet legalis system.

Blitz SBC type r boost controller.

Oil cooler, trans cooler.

E85 in the tank, most noticeable change yet.

R33 gtr Tomei fuel pump with ryco filter inline.

Deka 610cc injectors.

Emanage ultimate with map sensor.

Built re5 box with valve body, extra clutches and the converter unlocked with a switch.

17" Ku36 semi's on drifteks.

BC coilovers.

Plenty more, not performance based, the list would go on forever. :)

Had a little bit of a dissappointing result at the SAU:SA Dyno day today the M35 only pulled 126 KW :blink: It was on a mainline dyno, which they say under reads - but even so, would've liked a few more numbers. At least Ive got a baseline for future comparisons though.

Any mods? Stock exhaust?

If not - cheap mods- get a high performance filter for the stock air box and bump the boost up a couple of pounds. More expensive - 3in turbo back system.

Turbo has apparently been high flowed, I have the invoice for it - but it doesnt really give too much detail as to what exactly was done, I should perhaps ring them up and enquire (The cars Previous owner had it done)

Other than that, all stock (To the best of my knowledge). I do have the nismo adjustable exhaust, which has siezed up and Ive set to the 'silent' mode rather than the 'sport' mode. I guess this might account for 5kw if I opened it up :blink:

Ive got a new ECU on the way from Japan, should arrive this week - that'll probably dial up the boost a bit I suspect. For futher power considerations, the 3" dump is on the cards - Scotty has a jig to make them up now too.

Highflowed? When you put the 3in system on have a look to see if it has steel wheels and if so you should be able to push it up to 16 - 18psi if you have the ecu to support it. May need more fuel, afm by then (unless your ecu uses map reading) ...then you should have up to 100 more awkw!!

    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
