I know someone else besides me has had this problem, but I can't seem to get any clear answers on this. Here's the situation;
I have placed all my OLFA tables to 1.00 above 158 deg, but for some reason at idle I am still seeing 12.2 to 13.1 commanded AFR. I've checked my tune several times, but there must be something I'm missing. What else could be left? PE enable is stock except I moved the enable rpm down to 4500. I am in OLSD 2bar by the way, with the maf disabled.

Any help would be appreciated.

post the tune... log would be nice too, but post the tune.

Have you tuned the VE table?

The ve table looks great, the AFR looks good on the wideband, but its the commanded AFR thats bugging me. It would be nice if I could have those two to match.

Without a tune & scan its impossible to help.

Copy of tune and log attached, take a look. For some odd reason the tps does not show up on the chart but it works fine on the table.

Here give this a try.... Your PE enable from 1200 and down was 0% throttle. Down in that area with it being richer than your OLFA, it's value is used. When you come out of the rev, you are above 1200 and under 64% TPS, so it moves back to referencing the OLFA which is 1.0. That is the explanation for the behavior in the log.

Your PE tables are enabled at 0% throttle from 0-1200 rpm. So you're commanding 1.105-1.109 enrichment.

Thanks guys, any reason why the tps doesn't show up in the graph?

SuperC1

That's rite I forgot I did that a while back when it was n/a..

It is showing up. You're just logging TPS voltage instead of %.

SuperC1

iTrader: (4)

Ok, thanks guys...

It was set for %, went back and set it up again, but still no joy.

post your .cfg file that you are scanning with.

This is what I'm seeing:



The third PID from the top left is Throttle Position measured in volts. Is that not what you have? If not post the config.

Went out and made a test run today and the car is breaking up badly above 5k. I'm wondering if this is a fuel issue or spark issue. Log file is attached.

Thats in the table, I'm talking about TPS in the graph.

You have to log it here for it to work in there and right now the graph is for ETC%. Change both to Throttle Position % and it'll work fine.



If your wideband is accurate at all I'm surprised you even made it home, lol. It's a touch on the lean side. 19:1 should be more like 12:1.
