nice find!

Dont know if its a bug or not.. but the graph displays out of bounds...

Check the image attached...

This is using my .BIN file for the CA18DET
ROM PACK .BIN file produces same graph out of bounds..

So if I understand this right.... there will be a new Adres file for the CA18DET S13 ?

Denso's 550cc ?

Ashley, whats ur injector latency and K value set at ?

write down your current K value, load old baseuse map, use "resize injectors" option, then plug in q45 maf and enter just your written K value without changing VQ map Tried this ... This option does not work... as soon as I hit the gas pedal.. engine starts to die.. but thnx for the tip.....

I'm using the latest release 0.9.3.6.1.... Also have the latest ROM pack 2.0 I was using the Adress file in the MISC directory of the ROM pack.. ( S13_CA18_256_E_64pt ) I now used the one in the ROM directory... (S13_CA18_128_E) This solved the timing issue.. it now stays at 15 on idle... but leanin...

I am about to give up on this... I tried everything.. it just keeps leaning out no mather what i do.. i see the timing is at -7 at idle.. dunno why.. tried altering the timing with the CAS on the CA18... stays at -7 on nistune.. but engine does work differently.. in anycase.. no help with the leanin...

Here u go...

I just started to tune the cells in the fuelmap.. as u will see they are already in the 8 AFR area and my UEGO wideband still states its a bit lean ( 15 AFR )

Tnx for the reply Matt and Iceblade.. @ Iceblade... voltage in nistune doesnt reach 5v on WOT so i dont think its maxing out.. but never know.. @ Matt... I tried what u said.. followed the tuning guide word by word... But.. after putting all cells to 0, I can get the Idle very much dead on 14:7 AFR ...

Dont know if its a bug or deliberatly this way...

but when playing back a log... the Injector Duty Cicle graph is out of bounds..

dont know if it is caused by the % or other factors.. but here's a prnt scrn of a log..

This is with the latest release .. 0.9.3.6.1

Bump...

No-one had this prob before ? that might know the cause of this ?

Prior to installing the Q45 MAF... the engine was runnin normal.. with a stock S13 CA18DET MAF.. Idle AFR's of 13/14... Full boost AFR at 11.. After installing the Q45 MAF... ( using the mass air regulator feature ) the K - constant was set... at 236.. it starts and idles with no prob and AFR's at 1...

Tnx for the reply....

For future references or anybody who needs to know the latency for
DENSO 550cc Top feed injectors

latency = 850

i set mine at 1025 now since it idles better at this setting..

i Tried resizing the injectors using the injector resizing tool..
from 370cc to Denso 550cc injectors...

it starts ok
but then the RPM starts to drop and dies..

what else must i do ?
injector latency and K value ?
what do i need to do..
