Hello there fellow tuning enthusiasts.
I'll be posting a lot of EDC15 and EDC16 Projects from now on.
ALL Projects are made by myself following basic tuning know-how and stuff i learned during my studies in Mechanical Engineering and
Internal Combustion Engines Studies @ Technical University of Vienna, Austria.

I usually make 2 or 3 Tunes (versions) or steps twards the maximum exploitation of the STOCK engine's potential.
Feel free to write to me with suggetions or corrections on this topic or PM.

Hi,
let me expresses some comments:
v. 1.0 - looks like very mild tune, not bad, with the exception of closing the EGR and I'm curious why you advanced this way soi and what for?

v. 2.0 - here I can see larger bugs: durations maps - you should use proper extrapolation method (via excel is best). SOI - same as v.1.0.
Torque limiter - move max tq. beyond 2300revs (excessive force on the clutch and DMF) and hold it up to 3500-3700r - if you want real hp/nm improvement.
Besides EGR still not close enough. And boost pressure - these figures are mortal for stock VA turbo.

Cheers

Thank you for the advice and corrections, i still have a lot to learn!

Cheers! :)

I've recalculated the AFR and lowered the boost pressures so as not to damage the turbine.
Also Corrected the Smoke (MAF and MAP) Limiters or peak values and axis.
Egr Maps are original

All Duration Maps and SOI 8&9 are "extended" using proper trendlining and extrapolation via Excel.

N75 Map is not modified as it is non restrictive to the requested IQ and Boost Map, the ecu (as far as i read) can extrapolate by it's own when regarding this Map, by using parameters of actual boost and boost limit, it automatically adjusts the tubine geometry via the results of the N75 map.

Please do correct me if i'm wrong.

Thank you! :thumbup:

Hi,
-durations - still wrong, this figures fit rather into a some race setup. Use REGEXPW or REGEXPP methods. Or simply, may use this formula (70-50)X("60mg Value"-"50mg Value")/(60-50)+"50mg Value" = "70mg Value".
-SOI- Don`t exceed 28deg., add 1-2 deg at the highest loads for 8* max 10 * EOI.
-Tq.Lm - you don`t listen my advice, so..surely you know better :)
-IQ by MAF - why only part of the map ? We rising whole.
-IQ by MAP leave untouched.
-EGR - you want to earnestly feed the engine by exhaust gases (leads to clogged intake and lowing performance).
-Boost map - placing two identical columns is pointless. Just that, let the x-axis highest will be 60mg and with more than 60 ECU will use the highest column.
-N75 - Unfortunately, there aren`t so lightly, the ECU doesn`t regulate the N75 map for us. I suggest you read about rules of acting PID controllers.

Regards

Thank you for the heads-up, again!,

where the F***, pardon my french, is that Smoke Limit by MAP sensor? :oops:
i forgot about the EGR,
The methods metioned above are not excel based calculations, i've tried google-ing to find out their algorithm, but sadly it was unsuccessful.
The formula for linear extrapolation you wrote down generates VERY high values in duration maps for 70mg at mid-high rpm,
long injection duration will increase exhaust temperatures too high, i'm thinking it's best if i dial it down to 65mg/cyc.
i've checked with other forums regarding the N75 map, it does not figure out values on it's own for X-Axis values beyond (58mg, or what the stock highest x axis value was) but for IQ over it's axis values, it does stick to the last column of the map, wich as far as i read is constrictive enough to not let the turbo spin itself into dust, regardless of the IQ increase beyond that.
- i will not take that info for granted, not until i do some logs and see some actual figures.
