Re: Not hitting load targets
@JohnnyT load is a calculated result using, among many other things, your air flow. If your MAF is not on point, your load values will be off too. Unless you have the same trouble I'm having, apart from being unable to achieve load targets - no matter how much I increase the MAF values by, it will a...

Re: CL - OL Transitioning
The description of what the tables also suggests that we're not exactly sure how it affects the tune as well. I just described how it affects the tune... This is what I was referring to, BTW. See the screenshot attached. The table description should ideally then updated to say how this tabe affects...

Re: CL - OL Transitioning
Would you mind explaining a bit more here? I'm not sure I understand how you would ditch the fuel trims above these load points?mituc wrote: Usually on the tunes I make I ditch the fuel trims anywhere above load 1.063 or 1.125.

Re: CL - OL Transitioning
If I;m not mistaken, this is when LTFT goes to 0. The reason you still see non-zero fuel trims in open loop is because in your tune the Closed Loop Load Limit tables have values above the load you normally hit. . If you're referring to the 3 Closed Loop Load Limit tables at the top of the Absolute ...

Re: CL - OL Transitioning
If you're running lean or even rich at WOT, then your MAF calibration is off. When you're WOT the car is in open loop, so the MAF cal needs to be spot on. No it's not the MAF cal :lol: Trust me, this is not my first tuning rodeo. Been struggling with this for over a year. Hence me looking at other ...

CL - OL Transitioning
While I'm still struggling to figure out why my tunes run lean at WOT and I can't seem to get more than 2 load....I have noticed the ECU takes forever to transition to OL fueling. If I;m not mistaken, this is when LTFT goes to 0. Seems like it'll change right around the 1.9 - 2.0 load mark. Anyone e...

This is pretty much what I've been thinking is the issue for some time now.mituc wrote:I just hope the VT guys will fix this, must be some table or value which was not exposed yet and that these newer gen1 ECUs have (or maybe they all do but it's used in some specific situations).

Re: Not hitting load targets
Seems like a Gen1 issue then at the moment. But also not all Gen1 ECU's. Weird and frustrating though.

Re: Tuning for bigger cams
There are 3 things which helps spool: 1. richer mixture. the gasses will continue to expand and burn in the exhaust which will make them continue increasing volume there. Thank helpsspooling the turbine; 2. retarded timing. Pretty much the same logic ig gasses continuing to burn past the moment the...
