I've had some weird communication issues before, and after unhooking the battery and letting it sit for 10-15 mins and reconnecting it was all good.

Is your term x controlling the TB? If so why not just have the stock ECU power another dummy TB and call it a day.

Thanks for the heads up!

Key points:
Wrong plugs for boost
High IAT
Aggressive timing
Lean AFR (maybe from ltft) or from not checking after dyno

Frost - Does the LTFT carry over on these ecus? its showing -5% for...

I would imagine if you were really trying to get tricky you could put a relay in line with the coolant temperature sensor. Have one side of the relay be stock current temperature, and then when you...

SO I'm attaching the final "NA 92 Octane tune" and template so you can apply the tune changes to your file. (you will need to relabel the template file to .Htt as I could not upload a .HTT file

I had noticed some people asking for a focus SE file so here is a stock one from a 2018 automatic.

Yeah I made a mistake on the ECU type, and could change it. Lol sorry

I think I there is a table missing on my calibration for target fueling during misfires that is coming into play.

E38 ECM
T42 TCU
4l80e swapped
447 C5R
FIC 1000cc on E85 75% scaled
Currently MAF only tune


P0175 , P0172 System to rich codes permanent

Yall are some gangsta'S!

there are a few good posts on how to. few notes I took
Fueling
ECM 34290 -
ECM 34050 - Re scaled
ECM 34052 - Re scaled
ECM 34078
ECM 44453 - FA -- Increase to add fuel sooner
ECM 34230 - FA...

You can always add the extra timing into your main and idle maps in the 400, 600 ranges, And create your own underspeed correction.

Also Sometimes the other idle functions will block the adaptive...

More airflow in the VE map adds fueling (lets the ECU know there is more air, and it delivers more fuel accordingly). You need to fix your enrichment settings, and provide a better log. There isn't...

This table is kind of like a global fuel target table. If you double the AFR you just cut the fuel delivery in half. If your car is running rich overall you could use this to correct that, But that...

People change the stoich to 14.1 because most gasoline contains 10% alcohol now.

Another few things to consider is that if you are running MBT timing at idle then your idle advance undershoot cannot correct for a low idle dip (so you might want to decrease your timing some and...

You need to provide some logs with data. Idle info, etc....

It looks like maybe you are dealing with a few issues that are compounding the effect.
1. Your STIT and LTIT are both removing airflow. I would try to get these trims closer or raise the target idle...

There are some settings related to torque or friction under the torque page that will help.

IDK man some people take a while to get stuff done :)

It looks like you could be dealing with quite a few different situations. To get a grasp on what is happening you need to make sure that there are some basic settings working correctly.

You need...

Sounds like to me you have something abnormal going on. I would try to isolate your issue before assuming it's fuel related. next time it's acting up you should spray a little starting fluid in the...

If you installed a motor with the 58x trigger and the east you need the old 24x , you'll need this.

Sounds like you have a wiring/ ECU problem. Newer computers should not lose the tune. Why do you think it is the tune being lost and not something else?

Hey friend!
I would advise you download a few turbo tunes and compare them to yours to see what others have done. You have quite a few things way off in the tune and your lean issue reflects...
