Deceleration Fueling / Overrun RPM cutoff threshold tables

jcperformance1000 · **Joined:** Fri Nov 06, 2020 7:54 pm **Posts:** 4

Hi guys am I doing something wrong ive tried using the definitions for a4se900d on a rom that I've previously downloaded but everything is greyed out on ecuflash?

I've also tried using the definitions for the ecu to read it but it just comes up with errors and won't let me select a vehicle to pull the rom from the ecu? Am I doing something wrong somewhere?

I'm trying to get the decel fuel tables etc for the 16bit version of this ecu.

Thanks in advance guys

E2ZJ113G - USDM 2005 2.5RS MT/AT - 3E12084106

looking for resume rpm, resume pulsewidth and anything else overrun/DFC related

also looking for injector minimum pulsewidth and low pulse compensation, if possible

thanks

read the error details in your screenshot your missing 16bitbase from your definition setup. Undo what you did and try it again with the latest defs.

I Re-downloaded the alpha files then added the new map.

Has anyone got the address information for the relevant decel locations for this rom and for the a4te100g. Got address for the rpm resume threahold but not for the other ones.

Thank you.

16-bit roms are not defined outside of Carberry on 16-bit, sorry bud.

hello have a forester A2ZJA00P .. I am trying to find decel maps but i cant find the 1value ones i attach below a screenshot of what i found so far. If someone can help finding the 1value maps (rpm delta and initial injector enrich) i would be greatfull) I also trying to find the low injecotr paulse with maps for my rom i have posted in other posts with no luck hehe! hope someone can help

On the 2008 3.0R (at least D2PH410Q, likely other 3.0 & 2.5's) fuel cut is managed per bank so that sometimes a bank might cut fuel a half second after the other, other times both banks cut fuel in sync. On mine it's usually the richer bank (AF2 learning is -5%) that delays. At first I thought wide-band sensor AF2 was faulty as the graph showed much briefer lean areas after fuel cut. However comparing injector pulse width data the injectors were actually turned off later and for less time. Anyone know which other parameters could cause the injector cut delay I'd be interested thanks.

Could someone find the addresses for A2WD012B JDM legacy 5mt 2004

please,tell me. Deceleration Fueling / Overrun RPM cutoff threshold tables

thanks,

Pump for this, I'm needing the same tables for A2WD012A and they should be the same on these roms!

dschultz · **Posted:** Fri Jul 29, 2022 3:27 pm

For both A2WD012A and A2WD012B, maybe these, unconfirmed:

Code:

ALPHA_Overrun_Enrich_RPM_Delta_Activation              000658C8
ALPHA_Overrun_Fueling_Cut_Counter_RPM_Threshold        000658FC
ALPHA_Overrun_initial_injector_enrichment__pulsewidth_ 000658CC

Table_ALPHA_Overrun_Fueling_RPM_Resume_Threshold: size 16
Y_Axis 00065ACC
Data   00066732

Hi, everyone! Can someone help with finding the OverRun table for D2ZZ001E
I've tried the guidance on finding these values, but I'm not sure if these are correct. Please keep in mind I'm new to tuning and reverse engineering ROMs.

Code:

                             FLOAT_00078d44                                  XREF[2]:     FUN_0004a202:0004a290(R), 
                                                                                          0004a2f0(*)  
        00078d44 00 00 00 00     float      0.0
                             OverRun_Enrich_RPM_Delta_Activation_Maybe       XREF[2]:     Fun_OverRun_Maybe:00023716(R), 
                                                                                          000237f0(*)  
        00078d48 c2 c8 00 00     float      -100.0
                             Overrun_initial_enrichment_Maybe                XREF[2]:     Fun_OverRun_Maybe:0002373a(R), 
                                                                                          000237f8(*)  
        00078d4c 45 4a 80 00     float      3240.0
                             ThrothTipInEnrichActivationThrottle             XREF[2]:     Fun_TipInEnrichment:00023834(R), 
                                                                                          00023938(*)  
        00078d50 3f bb a5 e3     float      1.466
                             ThrothTipInEnrichActivation                     XREF[2]:     Fun_TipInEnrichment:0002397a(R),

                                                                                          00023940(*)  
        00078d58 42 33 47 ae     float      44.82

Hi were you able to find the table? I'm also looking for an example of this table for any 2005-2009 H6. The closest I found was a table with 250rpm for all ECT values above 40*C which didn't seem right.
