Hi all.
I had a good file with 386cc injectors, car works greate and linear
Today i replace injectors with 550cc and modified only TVUB , KRKTE , KVB, and TEMIN + TEMINVA. Nothing else modified in file.
Car starts and run ok.
I had a log with old injectors - attached file 386cc
I made the log again with new injectors and software - attached file 550.log
PROBLEM appear and i fill the car not run ok , like without power.
Major results in logs are the same between both logs : LOAD, BOOST , AFR.
Only few difference in Outside temperature and TIMING at the 3500rpm where new log decrease power.
Between these 2 logs (and what i feel) with new injectors power is lost and graphic looks very bad.
I don't have any explanation , only thing , maybe the ecu/new software must run more than 50Km to make adaption.
Please i need your advices.
Many thanks in advance.

both look equally terrible. You're severely underboosting in both. Not sure why you haven't bothered to fix it.

Thanks NYET, but i think between 1000 an 2500 RPM i think it is not possible in 3rd gear to be overboosting, do you agree???
After 5000 rpm will make modification , but for the moment other thing is the problem , like cal HP from ecuxploat looks horbile for log with 550cc injectors , and i don't find the causes.
Thanks in advance

I have no idea what you are talking about. Maybe we are looking at different things. You are going to throw a positive deviation code and go limp unless you bring up IMX

I talk about this problem from first picture. continous line is old log with 386cc injectors and discontinued line is the log with 550cc injectors.
Both boost grafic looks the same but calc HP looks horbile for the 550cc log.
Can be because the soft was in first kilometers after i rewrite in ecu and it makes adaptions?
 

ignore HP estimation until you get a proper tune.

actual is not even close to meeting req

the HP estimation is having issues due to interpolation/smoothing. I'd ignore it for now.

I'll try to decrease value in IMX before 2000 RPM at all % to try not be underboostin
Do you agree?
Because my IMX looks like this and looks aproximatly all imx standard and few stage 1 files:

what? No, INCREASE it

Are we looking at the same pictures?

You are underboosting from 3750 all the way to 5000

I look at this picture from 550cc log

1000-2750 underboosting
2750-5000 overboosting
5000-6000 underboosting

Sorry but we talk the same things?

Why your last row with 1350 hpa lower than previous with 950? 
You should decrease values in overboosting areas. And try to lowering boost at all and play with timing. This could give you better results

it is a modification in this night because i want to reduce a little boost there.
i have 1.5 bar and i try to reduce it to 1.4xx
i'll see tommorow if boost decrease there

Sorry you are right I had the two swapped. Try to make actual match requested or you might throw codes. Either reduce IMX or bring up requested.

Thanks again.
The codes will not appear because i modified ULS.
For increase requested boost i must increase ldrxn , and if i increase ldr in that area , the actual boost will increase too. Right?

Do not do that. You want to know if you have boost problems.

Doubtful unless you change IMX as well.

Thanks Nyet. I changed the imx for the rpm area 3000-4500 and my boost decreased but with very hard work on standard table because exists many ambigous things.
I tried to understood "wastegate before lin" from ecuxploat but values from there not folow the Imx or drl table.
Will try to adopt the linearisation methode for drl
10 ... all value 10
20...all value 20
...
95 - al values 95
and try to rectify boost only from IMX

but now i saw something new for me KFLDHBN
i think this map limits my boost not follow the ldrxn , what do you advice to me? can i disable KFLDHBN (put high value in map) ?
