Hey guys my mate asked me if i want to take my car to his mates chip control shop, and that he will do this to my car http://www.chipcontrol.com.au/aboutus.html...but im not sure if its really worth it because my car is a non turbo R33 GTS, and my other friend said not to do it because it will wreck my engine life and that it would only be worth doing if it was turbo. what do you guys think ?

I very much doubt they could remap an R33 ecu. Retuning your ecu will not effect your engine life, its how you drive that will effect engine life. While gains might not be as high as with a modded turbo motor, there will still be gains, bit more power through the rev range, and more economical is a possibilty. You would need aftermarket management or a piggy back ECU to tune though. Somthing like an SAFC might net you a tiny amount more power, and some better fuel economy, but you would need somthing like an Emanage Ultimate (in tems of piggy back) or a Power FC (for full management) to get the full benefit from tuning your engine, by altering ignition timing, etc. Once you start getting into ignition tuning, including the unit and dyno time, its going to end up costing a fair bit of money, for not too much gain.

well considering they do tunes for the LS1 and LS2, their tuning capabilities on your skyline will be pretty much zero. that isn't saying they are bad at what they do, just that they probably won't have the facility to alter your ecu (as it needs to be chipped first). the new commodores and falcons can have the factory ecu tuned much more easily than skylines

    • 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.
