new ID2000 injector setup

[darzamat]

hello,
i have 2000 golf GTI 1.8T and i will be using e85 fuel so i just wanted to upgrade my injectors with ID 2000. (i have 1.2.10 firmware btw)
i am not very familiar with the bigger injectors so i want to ask you guys if my setup is accurate or not.
in ID's web site , it shows 2000cc 's slope is actually 2225cc @ 3 bar.



stock 1.8T has 81mm piston bore , but i've upgraded them with 82.5mm...stil stock stroke (86.4mm). according to my calculation it becomes ~1847cc

so my req fuel would be ; 6.49 * (1847/4/2225) = 6.49 * 0.207 = 1.3ms

i set the injector dead time table as what the image shows above.
8v     1455us
10v   950us
12v  680us
14v  495us
16v  375us

1)are these values are always correct and accurate which ID give ?

2)i was using 870cc siemens injectors before and i was using them at 1.05 lambda (~15.5afr) while cruising for fuel economy. are these big injectors can do the same or should i use them
more rich while cruising ?

3)how does the accel. enrichment table calculated ? should i set it after VE table set properly or before ? any starting values you can suggest ?

4)these are my settings. any mistake or missing thing you guys can suggest ?

Thank you very much in advance.

The constant used to calculate required fuel is different for E85. I looked into this and documented it here http://www.vems.hu/wiki/index.php?page=MembersPage%2FSprocket%2FEthanol

For e85 you need around 42% more fuel.

Dead time of injectors you need to calibrate.

[darzamat]

aren't the dead time values which given by ID constant ?
i thought they're constant and i thoght i need to play only with req_fuel values.
so if it needs %42 more fuel , my req_fuel should be ~1.8ms right ?

Those deadtime values will be close but not all electronic circuits operate the same, i.e flybacks etc all have an effect thus its simply best to calibrate.
The help contains good information on how to calculate

[darzamat]

so if i need to calibrate them what is the calibrating procedure?
i mean how am i going to understand if the values that i give are correct ?
should start forexample , 8v or 16v ? increase or decrase the values ?

thank you

[darzamat]

that gives me some serious info. thank you.
so when i set the target lambda value to 0.8 forexample , i should see ~11.7 afr if my dead times are correct. but if i see richer then 0.8 i need longer dead time. this is ok. but longer for all 8,10,12,14,16v values ? or just one of them ?

while in this process , ego correction should be disabled right ?
