Nice Theo.

Glad you find it nice and smooth to drive. You'll have some fun at the drags I think. A programmable boost controller will take care of that drop off. Does the ECU have that function?

Are you still running off the AFM sensor? What Volts did you get up to?

Did you get a chance to over lay with my 3rd gear pull?

I'm curious about the AFM voltage also. Mine has peaked at 5.00v on the Informeter, so I wouldn't expect you'd go much higher than that.

No one wants to know about your 3rd gear pull Alex. :yucky:

Did you check the muffler bearings? Also, last time i was in your car; there was definitely a loose nut behind the steering wheel...

Haven't updated for a while not that I've really done much to it lately but did take it out to SMSP South Circuit again and managed to knock off another second off my lap time with a 1:08.26.

I've seen your cars get up to 5.12v or maybe a bit higher

Can't remember whose pipe it was, but I was flogging it.

We all know I pull hard, Dale....

:P

FYP.

Was that with one of Scotty's suction pipes?

I don't think my version; being (16ish% smaller cross sectional area) will actually get there.

farkin lol.

Ummm, I know Leons was up over 5 (5.02), as was Craigs(5.12) -both of them have intakes. Rudis was up there too(4.83), but didn't have an intake.

Another car with a highflow went 4.88v with no intake

I suspect 5.12 is the limit - I saw it maxed from 5800-6800rpm on Craigs on the nismo ECU. Obviously each sensor will have a discrepancy. I also think that each progression of the ECUs have different cut off points.

Now I'm lucky to see much over 4v... but thats with the upgraded MAF tuned in.

yeah still running the stock AFM, not sure of the voltage u'd have to ask.......

we did an overlay but because of the different diff ratio they where to different to match up.

i cant quiet make an accurate response on it yet but the gearbox is quiet different, like it still seems to shift quickly but it doesnt have the harshness like it used to so i dont know if its the same or slower................... my thoughts are if its softer its slower but i could be wrong. and we played with the gearbox settings on the ECU but couldn't really determine anything LOL

The timing drop between gears definitely works, it is just too late for the shift, as in it drops the timing after the gearbox has changed. It makes for a weird power drop after the shift. We zeroed it all out in the end. It is understandable when you think about it, as the Fcon has no idea what the gearbox is doing, so it must work off the revs dropping or something.

I changed to the Nulon fluid in mine, dropping the dextron III that Kewish put in there after the build. Surprising how much firmer it shifts, perhaps the Nulon is thinner filling the accumulators quicker? It positively thumps into second and third now causing all wheel chirps. :)

Less than a tenth separates the four runs! Congrats, very consistent Theo.

Did you try to vary anything to get a different (better) result? Were you able to get wheel spin at the start line or too grippy?

finally took the car down to pedders for a check over here's the list:

Front lower control arm & Inner bush - rear bush splitting.

Inner tie rod end - RHS has free play.

Steering rack - mounts are worn.

Front swaybar links - LHS has free play.

Rear X member mounts - both fronts are soft.

time to give Craig and Dale some work LOL

If your coming down, I'll bring the lappy and sort those codes for you if you haven't read them yet.

I'll be helping out at texi, but sure I will be able to help you out.

Is that the only code? And you're not doing texi cause of it...?

Get in there mate! Rip Skids- stoopid code is stoopid! Not going to break a motor cause the tune is super safe :P

OK any of the guys running F-Con's might be able to help me out and of course Scotty...........

i might aswell quote whats been said its a it easier, but any ways Alex did a cipher log on my car and then i passed on the details to Jez and the question is as follows:

Alex: "there seems to be a problem with the ECUs AFR correction, because it is cycling to each end of the ability to % correct. To my knowledge this is usually caused by the fueling map not being accurate enough in the low range/stoich range. You can try disconnecting the O2 sensor, and see how it drives, but let Jez know, and I'm sure he'll be able to touch it up a bit. If it gets really bad, just disconnect the HKS and run the stock ecu."

Jez: "Have u spoken to Scott? He mentioned that the f con is designed for 350z and the 02 sensors cant be used accurately or something along those lines. Have a chat to him but of course we can check it on the dyno or road with my wideband"

cheers Theo.

we done a data log and it got up to 4.8Volts could still go higher i guess didnt push it to hard.

      With my pre/power I use a remote trigger cable(3.5mm jack each end). I turn tv on, it turns both on via ARC. Or, just the pre with the remote or its streaming software, turns on both. Not that difficult at all. Obviously,  you would also want to actually update/upgrade over other factors in your life(bills, family, other hobbies, etc)

      Yeah, nightfall was very "meh". And I'm crap at pvp, so feels like everyone has cheats(it's just my lack of skill). Final shape has been pretty good. New raid and dungeon are pretty good. If you want to give it a go, probably wait until it's on sale. But, as usual, most of it feels very familiar.

      What Music Are You Listening To?

      By GTSBoy · Posted

      This morning was Kingswood's Microscopic Wars. It is the album's 10 year anniversary this year and we went to see them play the whole album as a special show a couple of months back. Was pretty spectacular.

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      Yeah I would like to try and get a ADM car to reduce issues with insurance. I've decided if I end up getting this car I will set it up to be a sleeper build, leave it looking stock/dad spec on the outside I wonder if you can just drop in the 400r/Red/Z ECU or better still use a flashing tool to copy the map off one. Backup the factory map and then flash the 400hp cars onto the 300hp cars ECU?

      Nah, yeah, nah. Speakers have a nominal impedance of 8 ohm that looks more like 6.4 ohm when measured. The receiver's amplifiers (all channels) are all rated to 6 ohm (I think, it's been a long time since I cared). The real problem is that many modern class D amps have aggressive protection circuitry that cuts off the fun if they think too much current is being drawn. And with my speakers having series crossovers, as opposed to more typical parallel crossovers, and big TL enclosures, they can certainly dip down to lower impedances at some frequencies and that easily triggers the protection. Pioneer receivers are somewhat famous for it, but even Denon, Onkyo, et al, all have many complaints against them across various models. It only does it when listening to music at high levels. You have to be putting your ears at risk to do it. But sometimes I want to do that. If I was serious about using it as a listening room I'd simply upgrade the amp for the front pair to a nice Rotel or something, and just use the receiver for signal handling and processing - although that would be a bit of a pain in the arse too. Have to switch on more shit, pre-amp volume vs main amp volume, etc etc.
