I finally have my AEM wideband set up to datalog on PCMscan woohoo! Well i did a few pulls today and found something that i am not sure is normal or not so if any tuners can chime in i would greatly appreciate it! As soon as i hit full boost for the first half second to full second i am showing still around 14:1 ratio then it drops quickly to 11.4 - 11.8 and holds that through the pull. Should i be showing a more rich ratio as soon as it hits boost? Is the guage reading slow? or do i need to adjust my tune before i melt a piston?

Each vertical bar in the background graph represents one second.

 

1) use a proper program like evoscan
2) is that holding 23 psi FLAT??? doesn't seem right

There will be a little lag in lower RPM (as the airflow is low, so there is a SLIGHT delay between combustion and when the AFR gets read. HOWEVER from this graph you are way to lean, you can run 12.5 AFR up until about 10psi then you need to drop to ~11AFR pretty damn quick (like b4 20psi)

 

It's actually 25-26psi. PCMscan only reads up to 22.78psi. It holds pretty flat though to redline. Drops to about 24psi. This is a third gear pull. It's exactly a half second of full boost befoe it richens up from the graph. I am going to get evoscan and take a look at the logs from that.

 

Ahh, even better reason to ditch PcmScan hehee

 

Just downloaded evoscan. Now if i can figure this one out. lol. i will get some new logs.

 

You will NEED todo the Mode23 mod, see stick thread at the top of this forum...

 

ummm.......can i send you my rom file, and some cash to set that up? I know i will mess it up

 

if you want

its easy thou! - there is a "mode23 illustrated" thread in the stick

 

I am doing it now but i ran into a few things where i am not sure. my internal ID is 52690019, so i copied that data for 52690019 from the evo x logging thread, and i pasted it in the 52680015 xml because mine says "inherits: 52680015" This is correct? or do i copy/paste the data for 52680015-52680020 and paste that instead?


Also the instructions say to go the misc. options and change the The 1st entry value from 0x05 to 0x23. The 2nd entry change the value from 0x05 to 0x23. The 3rd entry change the value from 0x42 to 0x52, but mine already says this after i changed the XML. I have not edited any of these and this is how they appear after only pasting the data into the XML.

Last but not least It seems i have a new XML file that says _MODS.XML ?? Pretty much blank inside the folder too. Strange! Let me know if this all looks right

 

1) forget the MODS file.

2) put the 52690019 xml into the 52690019.xml file.. Don't put it into the inherits file...

The 52690019 xml is specific to 52690019 so it should go in that file

 

Ok. The 5260019XML looks like it has almost no content in the folder! Just to be sure this looks right! I took a pic of where i posted the data.

 

Perfect!

Although you can push the </rom> down a couple of lines for "niceness factor"

 

haha ok i pushed it down 2 lines I will flash it in and hope it works! That's really all you have to do?

 

Yes - then in EvoScan just choose the right model EvoX and everything should work...

Don't log too much, just the essentials...

How are you logging AFR?

 

_you did actuallydo the ROM change yeh? ie change 0x05 to 0x23... etc?
