Camaro Zl1 LT4 tune

[hy_bmw_freak]

Well the weirdest thing would be why did your tuner reduce the Driver Demand table from OEM values if you added power mods to the car. Also, I don't agree with lowering the dynamic airmass to favor the MAF heavily with those mods. I think its important that you maintain other parts of the tune to ensure transient fueling is in line below 4000 RPM. Drive-ability is better too this way. But we all have our own ways. The Driver Demand table was very odd though.

Thanks for your help that is what i want to hear constructive criticism because i must tell him why and why not is the tune correctly he knows the basic technology but not with this control unit well i'm just the practice project if it doesn't work like i said or if there are problems i'll get on your balls or i go with Ben..

if i have new information i want it post here if im not to happy with the tune i ask Ben Charles again for the tune.
i want to post the results here and the maybe 60-130 times and 100-200 kmh with performance box.

Is it better to change to spark plugs on step colder ? ltr7ix?

[TriPinTaZ]

yes you need a step colder plugs with that setup

Hey danke f?rs schreiben und deine Hilfe also ich habe das problem mit dem druckverlust bei jedem schaltvorgang gefunden es war die bypassklappe die mader schraube war zu locker gewesen. auto h?lt jetzt den ladedruck beim jedem schaltvorgang bin soweit zufrieden mit meinem tune auto l?uft jetzt wirklich gut 100-200 in 5,3 sec und es geht noch bisschen was.
Ja wir schauen mal in die kennfelder rein was du meintest vielen dank f?r deine hilfe hast ja ahnung davon :-)

du musst ins tune ccm6 gucken nicht das andere das ist ohne tune das ist ja klar das dort ohne tune die drosselklappe nicht richtig aufmacht
guck hier ins log ccm10 11:17; 14 sec 11:17:17 sec

Es ist 1LE mit spoiler und aero an der front 305 er reifen das fahrzeug ist wie ein k?hlschrank ^^


thanks a lot guys for the support if i has any updates for my car and tune i will post here im waiting now for my heat exchanger from weapon x maybe it will be arrived 2038 so sad...
and my next mod will be a flexfeul sensor maybe add e30 to the 97 octance pump gas if the stock feul system can it make.

11:17 ;14 sec to 11:17 ; 14 sec this section guys is that tb issus or just layout and channel issues ?

So sieht es auf einen von vielen Begrenzern in deinem Tune aus

Dir ist schon bewusst das dieser log ohne tune also mit dem stock Datensatz ist !? Ich habe die 5.3 sek 100-200 mit einem anderen Datensatz gemacht was soll denn da noch begrenzen ??

Ich kann dir den aktuellen Datensatz schicken wenn du magst k?nnen wir gerne ?ber WhatsApp schreiben und kann dir gerne den tune schicken

Klar ist mir das bewusst. Da Du hier eine 100-200 km/h Messungen pr?sentierst, l?sst sich die Begrenzung wunderbar aus der Intervallmitte 150 ermitteln.
Nimm als Gegenrechnung P.I.D Booststeuerung 0,80 x 1000 Boost Disable = 800 : 99,7 : 1,50 = 5,349
Du kannst nat?rlich auch ?ber Map Charaktaristic 425 / Airflow TC 127 / 160 gegen rechnen. 425 / 127 x (160/100) = 5,349
Das hei?t, aus deiner Zeitmessung in die Begrenzung abzulesen, die hier typisch f?r eine Korrektur auf Werte ist, die OEM Grenzen entsprechen
Deine Tune kannst du mir gerne im Postfach legen, ich schau mal drauf.

hi guys i have question about the idle on this screenshot car has stock exhaust system and no tune at idle but you can see bank 1 oscillate its not so clean why can be do that ?
i have this issues after add headers change new o2 sensors too its that normal what can it be ? do i need to worry or just let it go ?

thanks for your help

[hy_bmw_freak]

I found the problem it was just exhausting leaking with the idle issues thanks for your help and support

But I have another question about hp tuners I don't want start a new thread.

Also guys if I do any logs with my car I just testing the few lambda settings also I try

Between .78-83 ~ and the results from dragy are excalty same from 60-130 mph or 100-200kph

Only the torque reading , airmass g/s and cyl/ mass it's less with less lambda also I mean example

If I read lambda .81~82 my torque and cylinder mass airmass g/s dropped little bit down but car runs fine and my dragy times exactly same.

And if I add more fuel like .78~ and my torque goes higher and my cyl /mass goes higher than before.

For me is that so the torque calculator on the hp tuners are not right and easy to read wrong or mistake with add to much fuel or not ??

I know air temperature timing and another thing's make a lot difference at the airmass g/s
And torque calculation.
But I tested it on same day same fuel and same temperature and timing.

I just changed only the airmass airflow vs frequency that's it also I mean on stock tune it runs about lambda. 060-65 like a wot and torque calculator was absolutely wrong...


Thanks for helping I hope I can explain my question about the hp tuners torque calculation

[TriPinTaZ]

Airmass is a calculated value based mainly on the MAF reading. if you add fuel via the MAF, then of course your calculated Airmass is going to read higher. The opposite is also true. This doesn't mean your ingesting more or less air. You're just altering the main value that is used to calculate airmass.


Manifold Pressure / MAP is the sensor you would look at to see if your changes have a positive affect on airflow. The MAP reads real time atmospheric pressure.

[hy_bmw_freak]

Thanks man you are awesome 👌

But about the MAP sensor what effects will be do if you run richer or leaner the manifold pressure just changed about the air temperature and mechanical changement or not ? Also if the air is colder it has more oxygen and it's heavier than if the weather is hoter than normal.

Also the pressure on the map sensor goes little higher than normal is that right !?example from max 15 psi to 16-17psi

[TriPinTaZ]

Richer or Leaner has zero affect on the MAP reading, unless your fuel mixture was so far off it was hurting power and efficiency. Then getting fueling right could alter the reading a bit but it won't be drastic at all. So I'm more inclined to say the simple answer is, zero affect on MAP.

Air temp changing the MAP? Of course. Colder air is more dense. The MAP sensor doesn't read oxygen content.

If your MAP sensor will read manifold pressure which includes the current barometric pressure. 100KPA(14.7psi) is 1 atmosphere but depending on weather, altitude, etc, the Baro may read under 100KPA or higher than 100KPA.
At WOT I would expect the MAP to read between 14-15PSI. With some mods like the MSD manifold you can see a bit higher than atmospheric pressure because it really is that efficient. If you're seeing 16 psi, that seems a bit unreasonable to be accurate. In that case, you should make sure you're monitoring the proper Hi Res MAP/Manifold Pressure for your car. I think MAP(Intake Manifold Absolute Pressure-SAE) is actually incorrect for some cars. I've had to monitor Hi Res "Manifold Absolute Pressure" for it to be accurate. Just depends on the car and ECU.
