That is a pretty accurate review, of a standard M35. Good thing is there's some pretty cheap mods that will address most of the 'bad' points.

I quite like the look of the back of mine now that I've made some changes, although I wasn't very fussed prior to that.

So for reference's sake, the Informeter is saying that my max coolant temperature is 98 degrees in my car. That is with a Koyo full alloy radiator to suit a V35. I'm pretty sure that before I cleared it, Dunc's max temp was 103 degrees celcius. Not sure if it helps anyone but just thought I'd add it anyway.

Now to figure out how to get my air cond thermo fan to start working. :rolleyes:

Interesting review.

If you do the dump pipe and exhaust, and the brake wire cut mod, I'd be interested to see this review again after...

All these will still not get rid of the abysmal throttle response....It might help a bit but its still shit slow off the line...

Thats the issue with going highflow, boost comes on later and our cars have bugger all low down power. (Mainly due to the low compression.) Mine seems to take off much better off boost with the larger rear housing on the turbo, as there is less exhaust restriction. Throttle response is great once you are on boost.

Well, yeah, once your on boost its sweet. Its the 0-30 kph I'm referring to...

So I know what Iain thinks, but what do others think about the "Nissan Sports Muffler". Would a dump and decat pipe make much of a difference to performance with the standard "rear pipe" attached?

it would......any improvement over the standard system would be better......but!!!!

I don't know how much restriction is it but you'll need the dump pipe just to get rid of that cat. I'd keep a cat in the midpipe but with the Nissan Sports Muffler do you still have the box of baffles in the middle of the car? If so a midpipe would make a huge difference!

I know where you can get all that sorted too... :whistling:

Scott put one of his dump pipes on mine. I could feel a little difference, but not a lot

This is interesting. A lot of people on here have claimed a dump pipe will significantly increase performance. Its all subjective I suppose.

My car is standard at the moment, I'm 95% sure i'm going to get Scotty to fabricate a dump pipe for me and AM Performance a Cat-back. I'm going to do a 0-100 before and after. Does anyone know of an App for Android to test this? I've got Galaxy S2, so something to use the inbuilt GPS I assume.

I think there's a thread about the SS Wagon vs M35 somewhere on here. Well last night I burnt off a new Calais but i'm 99.99% sure it was the SiDi v6 version. Still, it was a comfortable 'win.'

I'd assume an m35 with a turbo-back (and nothing else) would match an SS. Where I live the air is crisp and I think the turbo works a lot better than anywhere else in Australia.

I'd also be interested to know the weight difference (if any) between a standard exhaust system and a typical aftermarket one.

I don't have the box of baffles. It's either been replaced with a resonator or came with one from factory. The welds look way to clean to be a modification IMO, but maybe I'm wrong..

Actually, Dunc has the same muffler - does yours have the box of baffles?

a VE SS would comfortably beat a stock M35...even if you've got a whole TBE system...

MEH!

My CD player won't eject a CD and i'm getting 'CD Err F0.' I reckon it's just cheaper to sort out a connection to my ipod. Is there an AUX at the back of the player or do I need to buy an adaptor, similar to the V35's.

Oh and I didn't realise VE SS did the 100 in only 5.5secs, dayyamm

    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
