I do not make any changes to the ECU program, but I will try to be specific going forward (since someone already mentioned it, I will just use...
See BOLD below.
The fuel trims increase some on the short term as would be normal for any lean condition seen by the ECU from the O2 sensors. Neither the car or...
I thought it would be a good reference to show what part throttle boost looks like, and what fuel correction can look like during closed loop...
Okay, I did some looking in several manuals (including the one you have), and this is what I came up with. You are correct, sort of! Read on....
What year manual is that from? Does not match up with the trouble shooting data I have from Chrysler, and not with datalogging data on the O2...
No, they are not a 0-1v narrowband sensor, I have done quite a bit of research on them. The actual data is an approximately 1 v range high/low in...
Part of this depends on an explanation of what can be done with commanded AFR and its affects. Hopefully we can get an answer. Regarding the...
This is in line with my question about the commanded AFR, what areas does it apply to, and it's affect. You certainly do not want to be running...
See items in BOLD below. Mike, I appreciate you taking the time to join the discussion; this will be of great benefit to many people. In...

I agree with what you are saying, but unfortunately unless Fiat decides to sell the ECU code, I don't think any other solutions are going to show...
That is a very good description of things. Previously when only the SMT-6 was around, you did just that. Either toe out of boost or go to the...
See BOLD below I think the tuners have done a lot with what they have available to them, none of this is in no way meant to be a bad...
There is only one fuel map. Keep in mind that the unit is firing the injectors, not the ECU. With a 50% larger injector, it is using 50% of the...
It sounds as if you have a decent tune going on, and you are pretty happy with it. If you really want to know where things are at, simply install...
It will only stay in closed loop till you pass the throttle threshold to transition to WOT in the original ECU programming. Then it transitions...
See response below in BOLD. Thanks, I agree with what you said, and I don't blame them, it is their livelihood. If I can ever be of...
Okay, this is rather long, but lets give it a go. As I stated early on, I do not perform CMR tuning. I have had lengthy discussions with those...
Keep in mind, that boost is boost, regardless what is turning the rotating element. Superchargers tend to be more linear in power production,...
