Auto VE Tuning Data Filter Question

[jeff keyuk]

I have started a autoVE Tuning and would like to know is this the right filter I am using ,My goal is to get my AFR inline ,car is very rich!I have Data logged a few times,and it seems there is very little change each time,Thanks for looking.

Your TP filter parameter - TP not equal to 21% has me concerned - the filter will take out all other TP % cell hits.

I'd just go with the filter setting advised on Pg 13 of the AutoVE Tutorial (found under Help - tutorial - AutoVE in the scan tool program) in the first instance.

cheers

Jeff,

That filter is incorrect... (somehow your filter got crossed)

it should read like this:

Filter control: Include data frames

{SAE.TP} is changing less than 5% per 100ms AND
{GM.FTC.cell} is not equal to 21 AND
{SAE.ECT.F} is greater than 176°F AND
{SAE.RPM} is greater than 500 RPM AND
{SAE.TP} is greater than or equal to 1%

Jeff / Joe, I posted an example screenshot of an AutoVE map result and a basic filter setting in Jeff's other thread. Hope it helps.

cheers

Ok thanks macca.

[jeff keyuk]

Thanks again joe ! and macca for all your help!

Joe! In the Data Filter, I can not add {GM.FTC.cell} it say it is not valid .And when I go to the pid list,It will not let me add it to my pid list! That is the (Fuel trim cell number),and do I need to apply that to my filter???? If so how do I do it. Cheers

[joecar]

That means you did not log GM.FTC... so then you can leave FTC out of the filter.

Hi Joe! My B3618 in open loop I set them at 1.00 and B3605 I set them the same as the AutoVE Tutorial,My question is on the {Things to check}Did you want me to set thoses two table to AFR not EQR units.Thanks jeff

[joecar]

Regardless of the AutoVE tutorial, set B3618 to your target PE/WOT EQR (1.16 for NA), and set the last 2 columns in B3605 to the same value

( this does not cause any problems in AutoVE because you will see those values in the pid GM.EQIVRATIO )

( last few columns in B3605 in the tutorial is too lean for my liking; problem with B3618 set to 1.00 is that people forget to set it back to rich )

( note: if your BARO is less than 100 kPa, then set all the columns in B3605 from (BARO - 5) kPa to 100 kPa to the same value as B3618 )


I would prefer to use EQR units everywhere.
