Yes, a tephra mod's v5.10 ROM is pretty much ready to go. You just need to copy over the tuned tables from your current ROM to the tephra mod's ROM. For other features, find the tephra mod's v5.10 ROM thread.

 

Just as an update - following all of the instructions outlined in this thread, I've been able to log from my AEM UEGO through the ECU using EvoSCAN. The only thing you have to change is the voltage-to-AFR equation in the data.xml file for EvoSCAN as all wideband sensor are slightly different.

Thanks again, mrfred!

 

what equation did you come up with?

 

quick question. or a few

i just got a brand new laptop. mainly i tried to set it up for logging/tuning for the evo8.

dell dual core 2.4 possessor, 4 gig ram, 3 high speed USB-2 ports, etc i use the innovate LC-1/XD-16 and the new laptop does not have the serial connector like my older dell does. i started looking into USB to serial but then saw this thread. i was wondering if this has been working without any issues and how well it is logging AFR ''meaning acuracy and speed. is it better this way or better pluging the WB to the laptop.

p.s. i tried looking for the pins i needed but the links posted on P1 dont say ''pins here'' or something like that. im retarded so i need my hand held in finding them. hehe. thanks guys.

 

I think you're correct, as long as your evoscan's rear o2 is set to log MUT3C.

 

I have a suggestion, to write the eval formula in a different form, like an abstract equation.

I set this up over the weekend and everything worked fine except my reading at idle was in the 13s. I was thinking maybe I need to recalibrate my LC1, or I didn't ground it good enough. Then I realized my formula is wrong.

MrFred, you wrote an example, if your wideband is programmed from min 9 AFR and max 17 AFR the formula would be
(17 - 9)/255 + 9

Mine is setup min 10 max 20. So I did (20 - 10)/255 + 9.
I didn't realize that +9 was supposed to be the min AFR.

(MAX AFR - MIN AFR)/255 + MIN AFR

But on a different note, thank you MrFred for creating this mod.

 

another quick question. how do i modify evoscan to be able to add this
<DataListItem DataLog="Y" Color="" Display="Wideband AFR" LogReference="WideBand" RequestID="12" Eval="0.05859*x+7.35" Unit="AFR" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="0" GaugeMax="22" ChartMin="0" ChartMax="22" ScalingFactor="1" Notes="" Priority="1" Visible="false" />

also i have evoscan 2.0. and i was wondering what should be used when trying to log the AEM UEGO WB? thanks in advance.

 

anyone know what pin is rear o2 on a jdm that has no rear o2 as oem?
basically my car never had rear o2 but i want to input my LC1 analogue there for logging. my ecu is a 3 plug evo 8 2003

 

lee. pin 92/93 are spare ADC inputs (5V) that you can use. and i am pretty sure pin 73 is the rear 02 wire. logged via 3C and 1V.

i use pin93 and mut 39 to log 5V analog input... when my lc1 works

 

Should be MUT12

 

bump!


also i started setting up my buddies rom but i noticed that his rom is 94170008 and i downloaded 94170015. apparently its a replacement rom right? in which case all i have to do is apply the modded maps from 0008 to 0015 and reflash the ecu right? i noticed that the boost limit table is slightly different, 0008 shows rpm and the other shows something else. should i make it show rpms or keep it the way it is and only change the values?

sorry for so many questions

 

vmrevo9, your xml files must be messed up. The RPM table should be correct (stock values).

Try to uninstall and install ecuflash again.

And yes, the 94170015 will work on the 0008

 

+1. i also have an AEM wb. i'm assuming all works out the same? and i added the above coding to my evoscan ROM and all i see is "external wideband A/F ratio". is that what i'm supposed to be using?

 

bump

 

The address for RPM is wrong in your 0015.xml. Ill find it and BRB

edit: Ok this will fix it The RPM address is wrong it needs to be 6dd2

so like this

<table name="Boost Limit" address="3614">
<table name="RPM" address="6dd2" elements="9"/>
