just put on a high flow (had to replace my standard turbo as it shagged its self) and was looking at the injector duty cycle on my avcr, it seems that at low throttle that the % is around 90 but when i boot it seems to go down to about 30, is this right, does the % show how much of the injector duty cycle is not being used?

i also noticed that the peak hold shows the higher %.

also what is the (if lowest % is worse) lowest i should take the standard injectors, fuel pump, afm and ecu to?

i have a pfc and z32 afm, need to get fuel pump and injectors then tune it but untill then i want to get the most i can out of it safely, atm im running about .6 bar (9 psi) would like to up to .8 (12 psi) but also want to keep it safe.

any help would be appreciated.

Well 80% is considered a best practice ceiling... doesn't stop countless ppl hovering around 90% - 95%

If you right, and the #'s are inverted... I guess 10-20% would be what you'd wanna keep it under (over?) lol

Rem, thats at max load (airflow) the motors ever likely to see. Ppl keep that safety margin in case of a cold night, or a serious over boost.

if u have power fc why not just use the map tracer or use the display to show injector duty

so i take it u dont have rpm in your avcr?

^^ phhft, i fully missed that.. oh dear

i guess i should have mentioned that i have them but im waiting to get the rest and fit them all at once then tune it.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      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.
