So it seems odd that my car uses 87% of injector duty and 3% of warmup makes it too rich at times ( +8c in the morning).
makes it rely hard to tune warmup :lol:

2l 16v PSA engine 400cc injectors
dual map and combined VE 170% max load. rgf 8.4 E85
tps based tune, no map or baro used. both set up at 100%
the acceleration enrichment is too ~ 2-5% max
the 2023/05 gets credit to good working O2 correction, but still struggling with the big AFR jumps with 1% correction.

sequential or semi no affect to the mater.
car runs fine just the corrections are not very tunable.

2021/08 and 2023/05 work the same.

Sequential, and semi. Is the afr the same for both settings. A difference would suggest the injector OT is incorrect.

I know you not new here. :) I'm just throwing things at you because you are most likely fed up with looking at it. :D

We can probably help more if you post a tune and log pair.

No worries, there is no change needed with injectors sequ/semi. there is a 0.3-4 afr change but i get a biger one just by changing 1% on map :D

its like 10X off if i would need to change 0.5 afr and 5% that would be ok.

i´l get a coresponding tune and log on the next ride.
feels it´s somehow related to the tps based tune.

I haven't looked through your files, but I'd be looking at other causes. To keep percentages in-context, a +1% change from 13.0:1 AFR is 13.13:1 AFR. However, a 1% change from a VE of 22 is .22 but forced to a full step to 23, and at 13 AFR goes to 13.59 AFR. So unless a max deviation of about 0.6 AFR is a problem, it should be tunable to that error (+/- .3 of target). If you cannot maintain that error, there is likely a different cause/causes.

The following is generalized, without effects of rounding, WBO2 deviation, etc. From this, I would suggest scaling your VE table and Req_fuel to double the VE increment resolution as a test. First open your tune in TS, then File > Save Tune As to a new tune with a new name (e.g., Scaling_Test.msq), so you can always go back to your current tune. Divide the Req_fuel by 2 and burn, then select the entire VE table and use the Scaling button to multiply by 2. Burn that and save the new tune again.

This should result in a table with doubled values, but multiplied in fuel calculations by half, providing the same fueling, but at double the incremental control resolution. This means a full digit increase in idle VE of 22 to 23 is now 44 to 45, and the change in AFR should be half of previously, from 13.0 to 13.3 (+/- .15 AFR from target) versus the previous 13.6 example result. Let us know what you find, and we can go from there.

i did the change, warmup still does not have any more ability to tune it. 8% and it´s 12 Afr acc of 10% max nothing odd happened. Need to take a proper drive but first glance did not make difference.

i expexct it to go lean on the warmup but actually it got richer :?

like been said if the correction takes a full 1% step it´s too big. iat correction, injector voltage etc..

with map1 and map2 (e85 extra fuel) i have a VE scale of 20-300 if you combine the maps.

car runs fine still, all the ponys are home :D

Not seeing a warmup fuel issue in this log? I didn't realize you were using additive tables, so if you continue with scaled tables, you'll have to put some thought into system reaction. I again didn't look at everything, but did note you have Idle Advance as Switched (seeing odd idle timing in the log), which could cause some idle stability issues. I don't know if you've looked or tested far into that, or if you found it is an awesome solution for you with this setting and values. :?

Yeah i did notice that dual tables limit The ve and IT goes Lean when i made The rgf half and Maps 2x

Idle advance Works perfect, rock Solid idle and smooth. I dont use Idle valves.

I have a working good base map for gas ans 2 map IS The extra for E85 when used.

Ok so it's just a normal thing to only have 8% and less of warmup, and this gets worse with gas.

On The base things iat correction sufers from The same thing, resolution of a 1% jump is too big :?

Normal temperature swing here is 55C with The seasons :D

Perhaps I missed it, but I do not see your issue in the logs. Can you give times or a new log that shows where this warmup issue is, or where the 1% step is a problem? I ask, as I need to see and follow the problem to trace its sources (in data and activity) in order to envision a correct and effective solution.
