RC 1000cc car doesn't start well
 
I got some rc 1000cc injectors on my car.

I have them scaled dead on with idle/cruise trims at 0.2% and 0.1% (on evoscan, mitsulogger just gives 0/0)

Cold starts are ok most of the time. The real problem is with hot starts.

I have to crank it for about 4-6 seconds for it to start. there is a strong fuel smell as if the car is pig rich, but it quickly goes away after a few seconds.

Here are my scaling and latency settings:

I started with some values i found here and changed them that way:
-11.72v to 18.68v are the values i found *0.95.
-7.03v and 9.38v are some values someone posted saying it would help the problem i had. i didn't solve my problem.

I am currently out in the dark at the moment, and I have no idea what i should be doing.

Any help would be apperciated.

you need to reduce your 'Start up Enrichment IPW Adder' map.

What's your ROMID?

darwin_evo Oct 20, 2008 03:53 PM
i have a 2007 euro evo 9 my rom is 88840017.

darwin_evo Oct 20, 2008 03:55 PM
what will this table do to fix my problem?

RazorLab Oct 20, 2008 04:31 PM
yea, what tephra said, take out the additional cranking IPW at higher coolant temps via that table

kkarim Oct 20, 2008 04:39 PM
i'm interested too. how can i find this table for my ecu?

tephra Oct 20, 2008 04:40 PM
have you got the table defined in your xml?

lan_evo_mr9 Oct 20, 2008 04:43 PM
What's the actual table name for 'Start up Enrichment IPW Adder' under ecuflash?

tephra Oct 20, 2008 04:43 PM
Add this to your xml in ecuflash:
Code:
        <scaling name="ColdStartTime" units="ms" toexpr="x*0.008" frexpr="x/0.008" format="%.1f" min="0" max="500" inc="1" storagetype="uint16" endian="big"/>
        <table name="Startup Enrichment IPW Adder #1 (Main)" category="Fuel" address="5240" type="2D" level="1" scaling="ColdStartTime">
                <table name="Coolant Temperature" address="7100" type="Y Axis" elements="9" scaling="Temp"/>
        </table>
Then roughly halve all the values (560 -> 1000 = 2x as big)

lan_evo_mr9 Oct 20, 2008 04:45 PM
I have a cold start ussue, would adjustment of this table help with that also?

tephra Oct 20, 2008 04:49 PM
^ edited that a few times - make sure you get the latest :)

lan_evo_mr9 Oct 20, 2008 04:50 PM
Just installed the definitions- worked perfect. Cold start e85 adjustment tips?

kkarim Oct 20, 2008 04:55 PM
this is what the table looks like.

tephra Oct 20, 2008 04:59 PM
yup that's the right one.

so basically those ms values are unscaled by injector scaling, so whatever you have scaled your injector scaling to, roughly do the same to those ms's.

ie, for me

513 -> 1083 = 2.11111, so i just divided all the ms's in that table by 2.

I suppose for E85

513 -> 835 = 1.63, so divide them by 1.6ish...

darwin_evo Oct 20, 2008 05:00 PM
kkarim, this is what the table look like on my pc after i added the text to the xml.

i will try tomorrow to put in ecu with value /2 and see if it helps the issue.

i must do /2 only for the values on the right part correct?
