This car is from Brazil. I believe it would be a South American Domestic Market car, but i could be wrong???

My "problem" is after the car is warmed up and I start again (with E100) I can hear the injectors for around 40 secs then it all normalizes. Not sure if this is normal, but most of the time I wait and then drive, but wondering if there is a fix for this and if the pump duty tables would help?
Willing to donate.

2011 SADM WRX (CALID AZ1G800D | ECUID 74A2584007)

Thanks!

Well - if it's stock, post up the rom, otherwise, PM it to me - not promising anything, but maybe I can find the table for you.

Here it is. Let me know, and also let me know where I can donate.

Thanks a bunch!!

Hey Mike

I think I found the address for you.

Try:


<table name="Fuel Pump Duty" category="NSFW Beta" address="421EC" type="2D" level="1" scaling="rawecuvalue">
<description>The ECU will set fuel pump duty cycle to 0%, 100%, or one of these two values.</description>
<table name="Fuel Pump Duty" type="Static Y Axis" elements="2">
<data>Medium</data>
<data>Low</data>
</table>
</table>

AZ1G200J = 421EC

Your data location should be 43AB8.

Best to double check to be sure.

Will it fix your "noise"... no. I'm not sure what your hearing but increasing the fuel flow isnt going to help.

Sorry for the vague description. It seems that it's too much fuel. I had the same problem when I was running gasoline (stock injectors) first time it happened was when I parked and came back to park somewhere else. The car almost died (hesitated) and I thought it was something mechanically wrong. Hot restart enrichment tables? From what I was told they aren't defined which in open source?

Thanks mavstang73 - Mikey, that's the address. You know how to do it in Ecuflash? Just make sure you're running the latest 32bit base xml, and that you're at the highest user level (and have the 'show invalid tables' option checked). That way all you need to do is find the fuel pump duty table under "miscelaneous - thresholds", click on it, and edit map. Then just insert the address above.

Good luck!

Guys,

Yes, I know how to do this but have no idea about hex code / decoding / address / ECT.



I wanted to let everyone know, I have been looking for a universal solution to this since 09. I have 100's of hours into research and development for the GR hesitation. I problably have 75-100 GR's running around in the US/Canada/SA. Most have slim hesitation with hours of logging as well as trial and error.


This SADM car :

Its an 08 STi. The fuel system is completely custom. There is a tank, 300lph pump, an external surge tank, 3 parallel 180lph pumps, a 65lb/min turbo, and ID2200s flowing straight E100 ( along with lines and rails). I figured this would kill any possibility of the typical studders and bumps.

Well, it did not.


BUT THESE NEW TABLES DID!!!!!!!!!!!!!!!!!


I have alot of maps to get out now, lol.


I need to know who to donate to. Money is in paypal ready to go.

Also, any address for the 2011 USDM STi. I have tuned a few dozen, but have 2 or 3 with hesitations I couldnt shake off that well.


Thanks so much, incredible!!!

What values did you end up using for fuel pump duty? How are the trims in close loop now?

I believe dschultz had found this one
AE5I910V = 49144

I took a look at the hex and
AE5IA10V = 4A080
AE5IB00V = 4A0D4

Are there any other ecu id's for 2011 sti?

66/100






More work to do!

Again, any idea when this will be in the official defs?

Mikey,

Go enable fast poll (located just on the left side of connect/refresh and disconnect). This will enable rr logger to get samples as much as 20 plus queries/sec. Its gonna speed up what you're doing for maf scaling!

It would also be useful to define the switchover points for the fuel pump duty. I believe they're defined in terms of MAF, but I need to double check in Cobb. With those defined, you can move the switchover points which I've found can help cure the hesitation in some cars with larger setups.

Thanks
