EcuFlash tunning help

[nestoledo]

my setup is:

turbo custom
injectors 440 cc
pump walbro 255
ecuflash

my problem is the following one

load

0-100 it is ok

but 100-180 the AFR change of

2psi - 15 AFR
3psi - 16 AFR
4 psi - 17 AFR

before ecuflash i running with apexi neo and be fine at 10psi

now i change the maps with ecuflash but i cant run fine

these is my maps, please tell me that I can move to run fine

Thanks you

sorry for my English, i hope understand me

these are my maps

hmmm from looking at your map you might wanna change the ranges you have your loads defined as... ex: you got ...60 70 80 then 153?! that is a big jump. You should try something like this...10 20 40 60 70 80 90 100 120 130. Are you seeing anything near 180% load? post a video of one of your logs showing the load, rpm, wideband AFR, etc.

Also when you add load values in the load % area you also have to do the same int he ingintion tables. Cuz if your seeing 120% load your ECU will only be able to determine how much fuel to send btu it wont know what to do with the timing.

Do you have a fmu? i think your fpr is not allowing enough fuel out. even though you got bigger injectors and a upgraded fuel pump if you got a stock fpr it will still limit the fuel pressure.

How do you know how much load your engine is under? Are you datalogging with EvoScan or any similar software that reads your engine load from the ECU? Most turbo Lancer setups don't see more than 120-130% load from the ECU and that's at like 10psi. You might want to lower your load values and also adjust your ignition values like sykou stated above.

ok, finaly i can run at 10 psi. but for do that i was need to move to limits the maps of fuel and timing, also move to 0 the load open loop. and resize injectors the car run fine and very fast

ok so ive heard ecu flashing or piggyback, i understand that piggy back is limited and more so a plug and play while the flash you can change more. im starting to mod my car and i want to get into flashing but i want to understand it more so i know what im getting into.
