I have knock when i push acceleration fully because of low quality of fuel.

i need to tune up the ecu program to get better performance and no knock.

Ecu version is below:

rom base="NISSAN_BASE">
<romid>
<xmlid>14Y916</xmlid>
<hwid>1ZVMAT0NH</hwid>
<internalidaddress>23C0</internalidaddress>
<internalidstring>14Y916</internalidstring>
<ecuid>14Y916</ecuid>
<year>2001</year>
<market>USDM</market>
<make>Nissan</make>
<model>Maxima</model>
<submodel>NA</submodel>
<transmission>MT</transmission>
<memmodel>SH705507</memmodel>
<flashmethod>nisprog</flashmethod>
<filesize>512kb</filesize>


add 15% to mtp100 and injection multiplier

add +8 to red area in spark advance

add 15% from top to 4000rpm and 4000 to 6400 rpm 20% in fuel compensation

fuel target looks in attachment

lamda all -4 in all area and all 3 tables

5% from the second half of the MAF

Acceleration is very GOOD AND NO KNOCK but fuel consumption is very high.

fuel consumption is important here. And needs to getting lower.

before it was 13/5 in city 10 on road and now its 15/5 in each 100km

please help me with correct changing




thanks for helping in advance🙏🙏🙏🙏🙏
