depends on how much??

fixed the knock in the rear suspension, turns out the locking ring hadnt been done up and the strut was slowly unscrewing itself. problem solved! also reset the rear height, gave the springs some preload, so much better now. gotta do the fronts next.

i think the front knock is actually a groan and its the new poly bushes are not greased up enough :(

Good that you found the problem!:thumbsup:

How did you preload the rear springs Iain?

My understanding is that you can only preload if the damper is topped out (at full extension). In our case all you'd be doing is increasing your ride height.

Preloading springs is more of a motorbike thing due to the fact that at rest, with no rider (on a sports bike at least) the suspension is basically at the top of it's stroke (topped out), whereas in a car the suspension sits down an inch or more (at least) when at rest.

well, there is a height adjustment on the strut, so i measured the length of the thread to the ring 'flange'. this pulled the entire wheel assembly up as its shortened the length of the strut. then i screwed the 'height' adjustment of the spring land till it was captive (originally they werent) and then a little more. i measured both sides and they are even now.

the front i didnt touch as i couldnt move one of the rings for the spring land. ill attack it later and preload a little more.

dont wanna be a pain, but do you reckon you could take pictures?

Did the brake wire mod and installed a switch in the top of my glovebox. I did this not because I stall it up and launch it all the time, but because I live in the hills and drive on windy roads every day. Was quite skeptical about how much difference it would make as my car only has an exhaust, but went for a drive last night and was extremely suprised at the difference out of corners :rofl2: . Thanks to all that put the effort in to working the mod out :thumbsup: .

glad your happy with it. who needs the nismo ecu now :nyaanyaa:

because the stock ECU doesnt advance the cams like the nismo :P

Do the Mines/Impul/Gzone remaps play with the cams? I'd assume they do, but from memory the associated websites for them are all extremely vauge on what they actually 'do' :closedeyes:

lol low end cams? i dont know if Im wrong but I think scotts vmanage showed that the cams are retard down low.

of what part?

and no, not till next weekend lol

whenever your free to do it man, a write up how to stiffen pre load would be good.

Ok, I get you; I already run my shocks as short as they can go to minimise the amount of "droop" available as the shock extends.

Thing is, on mine, at the height I run, the spring is barely captive. Increasing the "preload" wouldn't make a difference on mine. Perhaps my springs are slightly shorter than yours?

thats entirely possibly about the spring length. but i think they are all the same.

the back is now firm, it was a little sloppy before. looking at it when i got home, i think it can go down maybe 1cm further at the rear. the boot was full of my tools so i couldnt throw it around too much.

the front will need to come down, or maybe just preload the springs more

Don't you want some droop? It forces the wheels to maintain contact with the road when you go over a bump. Having too much droop is bad as this will force the car to raise when cornering too much (dependant on spring rates/shock rates etc.)

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • 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.
