Copy values to 80mm maf of 2.4 - Ok, I will...



Don't touch axis of lambda maps
Don't need,copy values for duration of 2.4,

I don't know if the 2.4 injectors are the right ones for your set up...



I don't understand those word? Should I copy duration maps from 2.4 or not? Also Please Please Please tell me something about pilot or pre injection maps. Should I copy them also?

Here is the external boost gauge...

I'm in a very bad situation. Tuner made this file, but he did not even took a datalog. I told him, he said don't need to :?

Also In Dyno he did not even open the fan. IAT was last time I checked 78C degree... I need to fix this file. Please help..

PS: I know 1.9 JTDM cars with original injectos xxxx243 can go upto 280HP, mine is xxxxx308 and I know that it has little more IQ and it could help me to have better 280HP or near 300HP ??? I could not afford 341 DC injectors, they are in black market right now.. more than 1000€ for the set..

Today I've set the SVBL to 3501, and boostlimit map to 3501 Also. And Disabled the MAF sensor... to get a Datalog.

ps: MAF sensor was still connected. Here is the datalog file

Please review....

i said that you dont need to touch lambda axis,leave them stock
and the other,are you sure 2.4 injectors has the same spray angle to 1.9 injectors??
if dont has the engine can be damaged
in thus datalog i can see your afr its a little high,but its no the best,to do a good datalog,full throttle 1600-4200 rpm in 3rd gear

I would do this 3rd gear datalog no problem. What datas do you need?

For the injectors I think they are the came. Because 20V almost same engine.. Still going for 40.000 km

very bad map, man,i dont understand somethings of your setup,why you dont work with your oem boostvalve??
why your car can reach desired rail pressure??
why your drivers wish are too low??
this is a very bad file and youve got a massive overboost and high afr

That's why I'm doing it by myself. Tuner vas known to be good in Turkey, I went there and here is the file. Car cannot go more than 200km/h. And his file is here. I'm learning since then and tying to fix some of them.

I'm electrical engineer. That's why I want to use Electrical Actuator. And it works good. Only the VNT maps is stock. I would change them, I know how to do it, only it would take time. But rest of the ECU file is bad.

SOI is bad.
Durations are altered I don't know why,
REGEN Torque Maps touched why ??
Engine Start Torque Maps touched why ??
All the boost limit map is same and beyond 3000mBar ??
Smoke Maps are bad and done without calculated. Axis are bad.

So I'm here to learn all of them. I'm only 2-3 steps away from good boost map and ReScaled IQ up to 84mg

first start with the original file,tune drivers wish maps,copy values of 2.4 duration and then tune it properly,tune torque limiter,tune iq limiters properly,tune boost maps,tune rail pressure maps,leave soi stock while you dont know to tune ir properly(soi its a dangerous if not tune properly),tune afr maps(no need to touch axes)then log the car and retune file to match your expects :thumbup:
