Im wandering what realistic rwkw figures i should be geting out fo a RB20DET running 14PSI boost 600x300x76 frount mount,microtech LTX-12 running it all.W70 hks plugs only 2 1/2 inch mandrel ex .it seems to run very rich about 11.6 to 1 and usually at 38ish degrees ignition from 2000 rpm onwards its all in my R31 aussie skyline and its not what i had hoped it would be any ideas???

The 2.5 inch exhaust may be hurting your figures a bit but if it's tuned right and a healthy engine you should be getting anywhere between 150 and 160rwkw

As a reference mine made 164 on 12psi stock computer, pod, 80mm turbo back exhaust, 400x300x60 frontmount with 16 degrees base timing, in shootout mode.

The engine is in good condition and ive got a K&N pod and my intercooler piping is all 3" mandrel(yes i know 3" piping & 2 1/2" ex???)so its not reastricting anything.IM a little concearned with the exhaust but more so with the tune i.e 11.6 to 1 afr above 2000 rpm(thats runnin real rich) the base ignition timing is 10 as per microtech set up but hits 38 at 2000 & stays there?My problem is out here in country hicksville(just moved from BRISSY) no one knows how to tune microtech & i dont know who to use in syd or canberra (ANY IDEAS ON WHO IS A GOOD TUNER) When it all got up & runnin & tuned it made 150 rwhp which i figure is only 110ish rwkw IM NOT HAPPY & as i said out here is ****ed up i mean ive been asked three times why my radiator is polished & hangin out the front. So who do i see for a good tune?? I want reliability as well as kw & i dont want to be replacing the motor anytime to soon

Yeah, 11.6 is pretty rich but mine did it running 11.8 at the top end.

I'd be looking to bring the mixtures back to around 12-12.5 and have a good look at the ignition timing. It should really be running base timing of 15 degrees too. I reckon you'll find it's a bit of a dog with that timing.

I cant really remember but i think the microtech gives you timing on top of base timing on the display. I never really looked at that when i had one, mainly fueling.

For tuning in sydney you can't go past CRD in Silverwater but you will pay through the nose for it. I've never heard a complaint from anyone who has had a tune by these guys though.

Also Unique Autosports in Castlehill, JEM in Moorebank, V&E Rigoli in Wetherill Park would be worth a look.

      Mistakes were made, my R34 Story

      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.
