94 F-body LT1 solving problems/tune

[yoheer]

I have my older logs, before vette tables. There is no knock at about 4000. I'll try to make more cruising logs.
Also I dont like maf readings. 6-7 at idle. I'll try to clean, but I'm afraid he is dying.
No vac leaks. Checked
O2s readings vary to much (left/right)
Rarely I get right or left (dont remember)bank lean condition dtc.

Btw maybe someone has a good tuned file for stock or like-stock car?
I'd like to compare with stock. Is it noticeable chages in car behavior? I mean can I feel em myself

Here.

[yoheer]

Thank you. Can you write some description about the car, mods and what is made about tuning?

Absolutely OE, no mods, no tuning.
You asked to compare with stock. It's stock.

[yoheer]

Nope ) I do have lots of stock files. I asked tuned file for stock car.

[yoheer]

here is my combined bin
I will be grateful for the analysis and corrections.
To those who have f-body. It would be cool if you try this tune and say what corrections are required.

Guyz.
I compare corvette and f body trans tables. Can't understand one thing.
95' vette 2.59 gear vs 95' f-body 2.77 gears
Vette pressure table values are higher in all range.
But. Vette modifiers are much lower and even have negative values. F-body modifiers are higher and positive values.
What is it for?
Does it mean, that vette has softer shiftings and f-body has rougher shifting?
Why vette pressure is higher but it is gets lower with modifiers. What is the sense of all this?
Vette=high pressure+low modifiers
F-body=low pressure+high modifiers
And as a result pressure is somewhere at about same values. But the way cars gets this values differs. Why?

Good question, I can only guess at an answer, and my guess success rate is not good enough for me.

I.E.: the 4L60E line pressures for LT1 Caprices RoadMasters & Fleetwoods do not protect those 4L60Es from enthusiastic driving, at least not for very long.
Only notable exceptions are 9C1-LT1 Caprices and V4P 7000lb tow package Fleetwoods.

Since your car is probably heavier than a 'vette, I'd use the higher base line pressures & carefully study where & when the negative modifiers are applied.
My GUESS is that you can probably safely raise the negative modifiers to zero preemptively with no danger.

And what if i will apply higher vette pressure tables keepeng f-body positive modifiers?

Log analysis

Here is highway logs.
Dunno if i'm right but it seems to me lean. Blm ~135
If it is so then what are the next steps?

Start slow, make small incremental changes, save your previous version, see what happens.

Were I you, I'd use the 'vette base pressures AND raise all the negative modifiers to zero, based on my experience with several Caprices and a few Fleetwoods …
… but remember that I'm not there testing your car in real time with you.

Your shifts will probably get a bit firmer.

Either use the "Analyze" function in EEHack to give suggestions on changes, or export a CSV by clicking the "Main" tab and then clicking "Export CSV" so that you can feed that data into Trimalyzer. Note that in Trimalyzer you must change the default "Trim Input Type" in the upper-right corner to "+/- Percentage" in order to correctly read CSVs from EEHack in Trimalyzer.

Also note that if you have the MAF enabled, you cannot adjust the VE tables. EEHack/Trimalyzer will not give you accurate data for the VE Tables with MAF enabled--they will only be able to give you MAF adjustment data. If you want to tune the VE Tables--and you should if you haven't--then disable MAF mode and start there first. Once your VE tables look good, then switch back to MAF tuning. Or just tune the MAF and see where that gets you, I ain't yer daddy.

Thank you for the info. This is the only place where I can ask for help. Im trying to do all my best

remember, a blm of 135 doesn't mean you're really running lean, it just means it was lean for just a moment and the ECM had to add about 5% more fuel to fix it. it's nothing to worry about. that's what closed loop is for. you could add 5% of fuel to that area so next time it doesn't have to adjust.
