Personally for my car throttle response was better....I wired my grounding kit to my throttle bodies. Shifting was better (auto). If you read g35driver or myg37, a lot of them will say the same thing. I think it's also all the electronics and drive by wire system.

Camr33 - I'd think your car may have a tune done to it if it felt really different in terms of acceleration and power. Like Greg said, some tunes allow stock ECU to be used.

I wouldn't say its in my head, as I didn't know it had a grounding kit until after I bought it.

But it definitely had a definite power advantage over the others I drove, like I said- is there a way I can tell if it is chipped or has aftermarket cams

PS: It could also just be a tight engine... My V35 350GT goes hard (compared to others) and I'm not surprised... with such low mileage and the condition it was in when it was sold, it makes sense to me.

So thought I would get a baseline done on my V36.

Vehicle is stock in the way of performance mods.

Car year: 2012

Millage: 20,500km

Trans: 7sp auto

Fuel: 98 octane fuel

Temp: 26-28 degrees with low humidity (perth summer)

Dyno: dynapac (hub dyno)

Power: 220kW at 6600rpm

Torque: 340Nm at 4600rpm

I feel that these are unusually high numbers thoughts?

It's not out of the question, there are a number of different factors at play not withstanding that particular dyno itself may read a bit optimistic on average(If it is a hub dyno i think they tend to read a bit higher than a rolling dyno anyway, but not much).

If you do get performance mods make sure it's on the same dyno for this reason so it will give you a more reliable comparison.

Will do, my intention is to keep continuity with dynos.

I will shortly be adding some:

Fast Intentions HFCs,

Motordyne M370 intake and

Cash flow dependent the Takeka CAI

Then dyno, retune an report back.

On a side note: I was having a chat with the tuner today and he said that the ecu learnt very quick eg: he did 6 runs the first 4 ran rich AFR then leaned out in the last two without any input from his end.

Guessing most of these v36's are autos with stock ecu thus the 180km/h limit, can everyone chime in what gear was the dyno run done? im guessing that will affect these numbers for sure...

For example to do a whole rpm band dyno run, they would have to be done in 3rd gear as it would cutoff at 180km/s in 4th before it redlines...

just my thoughts :)

I requested the uprev lic be aquirred for my vehicle prior to the dyno runs to allow the removal of the limiter which for reference was reached in 4th in the low 6000rpms (first run before limiter removal.

I raised the question when I was informed that the run was undertaken in 4th "why it wasn't performed in the 1:1 gear (5th on the 7sp)." The tuners response was the power that is made by the car isnt dependent on the gear, rather the gears determine what rpm that power gets put down in... For example the peak power remains the same in all gears it's just seen earlier in the rpm band in lower gears.

Now this is just my understanding (not nessarilly correct), so jump in with any corrections.

Now torque on the other hand I would assume is a different subject?

What dyno machine did you use?

I got 180rkw with stillen hfc uprev base tune on dynodynamics.

I ran the diagnosis with obde2, no error codes, Afr is around 12.2 under wot.

I got 5AT 08 SP. Going to get Takeda Rc2 Cai and go for a proper tune when i have time, prolly have to inject more fuel after cai to get the afr under 12 with wot

      spot the stagea

      By AnimalGarage · Posted

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.

      OK, if it idles at 1000+ with the AAC, its not an idle airflow problem. The cold start valve just gives extra air when the engine is cold, but you have enough air without it to idle at 1000. I think you are back to a fuel problem, sorry. Can you see the fuel pressure staying constant or does it drop as the revs drop to a stall?
