Johnny, I have never really looked at nistune maps... Can you explain the high values in the ignition map. 145-170?

ahh the values go "retarded" when you enable knock feedback, essentially when the ECU detects knock through the OEM knock sensor in those "retarded" cells it will read from the knock map.

So his tuner was just very conservative or does this just look like he had no idea? 

More like his tuner is a tuna.. aka a moron. There's too much timing in the map and there's a high chance it's beyond MBT for each of the load points.

I've asked for logs in 3rd, will look at them soon and advise him on next steps. Those timing figures are for e85 and even so that's considered high.

Hi Adam good power! Looks a little laggy from the chart (as you would expect with those cams) doe it seem like that on the road? Do you have a 1/4 mile time?

Nice looking coupe!

Thanks mate. Comparing my old graph with pon cams it picks up better at different points over the rpm range, makes a little more power over the range too. I have also retarted the exhaust gear 2 degrees with the new cams witch I believe is helping the bottom end a little. She was trailered there and back, basically the engine, suspension, tyres and brakes will be a untested setup for nationals at the end of the month :blink:.  I will report back then and hopefully have some better feed back.

Cams were chosen for my new engine-that's in the build still and will be better suited IMO. 

R34GTT with Rv-2 Atr45sat Cbb Int gated bolton turbo on stock manifold. Stock engine rb25det neo motor, I'd 1000 injectors, walbo pump, Pwr cooler, 3 inches turbo back cooler and 4 inches intake pipe. 324rwkws P98 fuel

Hey that looks like good bang for buck! I presume you used a Nistune chip - did you upgrade the fuel pump as well?

Hi Guys,

Final tuning completed yesterday - 2 visits and all done.

mods: GTX3582R Turbo, Apexi ECU, TOG Modified High Mount Manifold Schedule 10, FMIC, Plenum, Genuine Z32 AFM cold side, Splitfire Coilpacks, 650cc Top Feed Injectors, AEM rising rate FPR, Top Speed 345lph in tank pump, Greddy FV BOV, 3 Inch to Cat, HF Cat, Twin System to rear, Turbosmart 45mm Hypergate, 50mm wastegate inlet and outlet, 4 inch intake POD, Throttle body going in the bin and back to stock,

fuel: BP Ultimate 98

power: 360kw 482hp - 22psi high - little laggy down low as expected - as long as I drive to suit should be quite fun.

oil: Nulon 10w 40 Synthetic

useage: Daily Driver - Might Hill Climb and Possibly Vic Time Attack if I can get in. Just for fun

lifespan: I have owned the vehicle for 12 years never any engine failures just a water pump - Lifespan for 360kw so far 24 hours without running

failure: Water pump - as for Dyno failures clutch slip on the last power run - as mentioned 12 years on the same clutch not bad at all.

comments: With the clutch slip the Dyno results would have shown different - its all good though should be putting about 600nm down. If I could change anything maybe go with the A/R 0.63 on the rear.

Finally made the club. Completely stock 25 Neo including all manifolds. 

mods: Borg Warner Airwerks S257SX-E TS 0.83 on stock manifold, Tial MV-R EWG, Bosch 1250cc injectors, Walbro 485 with hardwire mod, 3" turbo back exhaust with highflow cat and HKS Super Drager muff. HDI IC, 3" intake, Nistune with feature pack 2 and flex fuel sensor. Bosch R8 coilpacks

fuel: BP 98/ United e85

power:266rwkw 98 + 18psi/302rwkw e85 + 19psi

oil:Penrite Racing 10/Tenths 10w40

useage: Weekend warrior/ some track days

lifespan: 172000 + 1 week

failure:

comments: EWG needs more spring (0.3 bar) so has some lazy spool (140kw @ 4000rpm) and drops 2.5psi from 5500 to 6800 rpm, so gate is blowing open.

This is a setup I'd like to see!   I've felt that the S257 SXE is an untried hero for the RB budget performance crowd. Pics please, and show us the dyno sheet.

Any idea what sort of timing this thing is taking up top?

What does it drive like?

That was my thoughts, and at about $1200 AUD landed, its worth a shot.  Not sure on timing, but knowing my tuner it wouldnt be anything crazy. Because of the EWG spring drama, its not building boost like it should, and its dropping 2-3 psi upto. So once i have that sorted i think driveability will be much improved. When it is on boost, its very punchy and the spool noise is pure jizz

    • I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.
    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation. 
    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
