What did you do to your Fiesta ST today ?

[Dream Making]

I personally monitor IAT, BOOST, WGDC, timing correction cyl1, AFR, and OAR...

If you're going to load a tune I highly recommend an intercooler, and the mandatory mod is definitely a RMM.

using the OBD port or with gauges?

Cobb accessport v3

That's with an access port, i use torquepro and an OBD2 dongle to monitor much more... If you're in Europe you don't get access ports for tuning

Whaaat? So for us folks in Europe we only have obd

As far as I know, however with an OBD dongle and torquepro app you can monitor everything and more than what the access port is capable.. like I have one gauge that shows the heat soak from IAT at the filter to Intercooler and also tracks ambient

Yeah I do have torque pro as well but I'm not able to see the afr

That's weird, I definitely have it on mine... There's a way to add/update your PIDs you might want to try that, I used this thread from a focus forum to help add a few

Waste gate duty cycle, and yeah even in a stock tune it's good to track timing as negative corrections can be a sign of engine issues...

So I’ve been monitoring ignition corrections and WGDC and have been enjoying learning more about them. Thanks for sharing. I was wondering though, at WOT, should I be getting higher than mid 60’s% WGDC? I’m stock with the COBB OTS stage 1 91, drop in filter to be installed this Monday. Higher percentage=less open more boost as opposed to lower percentage=more open less boost right?

Correct the higher the percentage the closer the gate is to being shut, resulting in more boost.. 60% isn't a sign of issue, our engines determine boost by the torque demand. If the engine is making sufficient power(cool air, good fuel) your boost request/WGDC will be less. What's your max boost been?

Just over 20psi. For some reason I thought it’d maybe be more by 2-3psi. I also noticed ignition correction went negative on all cylinders from just below zero to -2.34. Positive numbers were pretty much all close. I noticed they’d go negative when I was just leaning in to the throttle. Maybe 30% or so. I know that doesn’t mean much without considering knock count. How long does it take the ECU to learn and adapt to the new tune?

What was your OAR? Cheap gas will cause those negative corrections same with higher IAT temps

Thanks to @ron@whoosh I got some bling for the work truck, I wanna say the flavor is blood orange

-1.00. I’ve seen 0.97 a couple times but 99% of the time it’s -1.00. It’s been cold here in SoCal lately but I haven’t checked intake temp.

I get the same shit with Cali gas, but I have dizzy stage 2 and Max boost is right around 25 for me. I've never seen the 27psi it claims but my WGDC is never above 82% but I'll get negative corrections that I think are related to the passenger mount/fuel, once temps rise I'm going to try adding in some 100octane see if that eases summer time knock corrections... That being said even though I have never hit max boost i feel it's just cause my engine is strong and meets the target parameters without it 🤷🏼‍♂️
