Hot Start Enrichment Tables Found!

2bfi · **Joined:** Fri Dec 25, 2009 12:46 pm **Posts:** 93

Could someone please check if I got it right for an AZ1J500G. I just searched for the pattern using a hex editor.

Code:

   <table name="Hotstart Enrichment Decay Delay" address="C7C52"/>
   <table name="Hotstart Enrichment Decay Step" address="C81B0"/>
   <table name="Initial Hotstart Enrichment (High)" address="C81A4"/>
   <table name="Hotstart High Enrichment Activation Threshold (Coolant Temperature)" address="C8194"/>
   <table name="Hotstart High Enrichment Activation Threshold (Intake Air Temperature)" address="C8198"/>
   <table name="Initial Hotstart Enrichment (Low)" address="C81A8"/>
   <table name="Hotstart Low Enrichment Activation Threshold (Coolant Temperature)" address="C819C"/>
   <table name="Hotstart Low Enrichment Activation Threshold (Minimum Intake Air Temperature)" address="C81A0"/>
   <table name="Maximum Non-Idle Hotstart Enrichment (Post Delay)" address="C81B4"/>
   <table name="Hotstart Maximum Non-Idle Enrichment Delay" address="C7C56"/>
   <table name="Hotstart Minimum Enrichment Limit Runtime" address="C7C54"/>
   <table name="Hotstart Minimum Enrichment (During Delay and Runtime)" address="C81AC"/>

Checked the addresses out - yes, all correct.

Thanks for checking.

I hope this solves my hot start issues.

Update: I've been using this for the last two weeks. Hot start is good. Before, I had to crank quite a bit before the engine starts.

With ID1000 injectors & stock intake, I reduced enrichment by half.

With ID1000 injectors and KS Tech 73mm intake, I didn't have hot crank issues. But, IATs were very high. That discussion is for another thread.

I think I have found the values for AZ1G900C

I have not verified them yet. Could someone double check ?

Code:

<table name="Hotstart Enrichment Decay Delay" address="c74fe"/>

<table name="Hotstart Enrichment Decay Step" address="c7aa0"/>

<table name="Initial Hotstart Enrichment (High)" address="c7a94"/>

<table name="Hotstart High Enrichment Activation Threshold (Coolant Temperature)" address="c7a84"/>

<table name="Hotstart High Enrichment Activation Threshold (Intake Air Temperature)" address="c8014"/>

<table name="Initial Hotstart Enrichment (Low)" address="c7a98"/>

<table name="Hotstart Low Enrichment Activation Threshold (Coolant Temperature)" address="c7a8c"/>

<table name="Hotstart Low Enrichment Activation Threshold (Minimum Intake Air Temperature)" address="c7a90"/>

<table name="Maximum Non-Idle Hotstart Enrichment (Post Delay)" address="c7aa4"/>

<table name="Hotstart Maximum Non-Idle Enrichment Delay" address="c7502"/>

<table name="Hotstart Minimum Enrichment Limit Runtime" address="c7500"/>

<table name="Hotstart Minimum Enrichment (During Delay and Runtime)" address="c7a9c"/>

Everything right, other than:

Code:

ROM:000C7A88 Hotstart_High_Enrichment_Activation_Threshold__Intake_Air_Temperature_:.float 0.0

Thanks td-d.

I somehow edited the source definition from the similar rom I was using for that one :oops:

.

For people that don't want to use IDA, I have found that ecmerge does a great job of automatically lining up the table sections between two similar roms.

I would really be thankful if you guys could get the tables for the following:

AZ1G800D
AZ1G700H
AZ1G800L

Thanks!

I'll have a look for you.

Could you grab defs for A2UG000J (USDM 07 STi) when you get a chance?

Thanks!

It seems that the A2UG000J is a deprecated rom, being superseded by the A2UJ000J. The changes appear to include altered logic instead of a simple calibration change, so I would recommend switching to the A2UJ000J rom if possible.
