I noticed in my copilot advisor that my afr is set at 14.7 so this helps alot . I'm still struggling through this and hopefully will have it sorted thanks to you.
Thanks for this tutorial. I think you missed something very critical for anyone attempting to use auto-tune. Have to set the Min and Max Base Maps. I do this by multiply off the current base map.
I have a pre tuned base map but I do not want to reset my whole tune in order for the pfc to relearn my larger injectors. How would i setup the injectors in the pfc in order to adjust my tune for the new injectors?
First off, resetting your pfc won’t make it relearn new injectors. What software are you using? I would recommend FCEdit. You’ll need to input the various information such as input lag/voltage, injector sizing compared to stock, etc. so long as the values are correct, then the map should be almost perfect, but would probably need some slight tweaks as there’s always variances between injectors, flow rates, etc.
If you adjust your target afr map do you need to make any changes to the inj map? Same with the base map, if I change the base map do I need to change the inj map? I recently changed the target afr map and my car is hesitating in boost at 4300 rpm but I’m pretty sure it wasn’t doing that before.
so the Target AFR map in copilot does not affect the tune at all. It is only used as a reference when auto tuning. CoPilot takes the reading from the wb02 and compares it to the value in the target AFR map. It then either adds or removes fuel from the base map until the realized(real) AFR is the same as the target afr. now, technically the base map should be the same as the target AFR map, and in theory you should be able to make adjustments to this map based on your target afr and it should match up with your wb02, but that is the theory and only the case if the INJ map is perfect, which it rarely is. The base map is what you should be making changes to.
Thanks for answering some of my questions, I figured most of it out only the longer that my car uses the auto tune function the worse the engine runs.. as time goes by my tune seems to be looking good in the logged afr section but it is badly stumbling like it’s way too rich and chokes. I couldn’t tell it it was too low ignition since I’ve been lowering it where I see high knock mostly at the very low rpm where it drops under 1000 rpm. Also the car said it was pretty lean at higher rpm going into boost so I richened it up and now it won’t go into boost like it’s chocking and has a 4400 rpm redline. I’ve got a couple broken exhaust manifold studs, maybe the afr readings are off? Maybe the widebacd is too far from the turbo? I did the recommended 24 inches..
Speaking from experience, any sort of exhaust leak will drastically change your AFR's, so I would fix that first. Also, I would watch out for the knock values and do some research to find out what's true knock and just noise. In lower load cells, it's more likely that it is just noise and not true knock. For me, I found that If I had ignition autotune enabled and i'm just idling, it throws things way off. I would recommend locking the low load blocks so no changes are made to ignition timing in those cells, and focus only on load/WOT, Roll on throttle, etc. As for the fueling, that will more than likley be because of either a mis-calibrated wb02 or an exhaust leak. a quick test is to turn on 02 feed back and watch what the AFR's are. the PFC will try and get an AFR of 14.7-15.1, so if you see crazy AFR's when standard lean cruise/02 feedback is enabled, then there is a problem.
@@PatrickLipp after more testing it turns out it was the opposite of what I was thinking. Whenever my tune goes just over 14.8 into 15 it stutters and won’t go any higher in rpm. I tried leaning the tune out and it got worse like every rpm would do it so that led me to believe the tune is running leaner than it says. I richened the tune and smoothed it out best I could and it’s back to running good at all rpms out of boost at least. I’ve still got some progress to make still since when I step on it and go into boost it hits 14.8 afr and stutters still so I’ve got to add quite a bit of fuel for the high load areas. 14.8 just always seemed like it would be an ok afr so I was confused but I’m guessing it’s much leaner than it’s telling me. Sadly I cannot fix the manifold studs, I’ve already broken a couple drill bits off into them because I didn’t have reverse bits so now they have a titanium bit wedged in the middle of them. My question is has your tune ever ran so lean it wouldn’t accelerate? If so what afr did it hit? I’d like to find out what 14.8 really is for me car so I can adjust the numbers to where they really should be.
Hey man! I appreciate the series / guides, but I'm running into an issue (hopefully you'll be able to respond) So I got me wideband, and autotuning setup (copilot reading AFRs same as my wideband gauge, and all the green boxes are lit) I select "START" for the autotune process, but it doesn't actually do anything. It claims autotuning is in progress, but I set my idle target AFR to 12.0, and even after about 5 minutes of idling, nothing changes in my new base or inj map. Nothing changes at all, so I'm not sure what I'm doing wrong?
Great explanation

But guys, please remember, if you break something, he is not responsible.
Great vids by the way.

check the Throttle position requirements. The default setting is at least 1% throttle, so idle won't tune.
@@PatrickLipp that might've been it. Anything else?
@@corbinxtitus get this figured out yet? Let me know. I had trouble getting it going but now I'm slowly logging and auto tuning.
