need calc vet help

[whackem04]

I installed a new cam and now trying to get calc vet to look good but my graph looks crazy would like some help or even little guidance. It seems ok till we get to idle then its falls on face and get map pressure code please help

[joecar]

You will need to do idle tuning...

[whackem04]

Other then the idle problem I was asking why my calc vet table looks so crazy when i apply filters and input the data to my ve table. Im just trying to make sure i get it right. I have read almost all of the idle links. Hardest part about having all those links is one can get confused bout what was changed in there tune and what we should change back to default after tune is tuned. Also why am i geting a MAP performance code? Thank you for your help.

[whackem04]

am i suppose to take this data and go line by line and smooth out the tables then run calc.vet again till there is no correction left? or am i missing something? Thanks for ur help.

[joecar]

No; the calc.vet procedure gets your MAF and VE nailed in one attempt.


Can you post a screenshot of the CALC.VET map you used...

did you do a paste of this into the VE table...?


I'll take a closer look at your log files later tonite.

[whackem04]

Thanks for the help. I completed a longer fuller log and have attached everything. The air mass is definately different then the stock one. How do i fix all the cells I didnt hit in the log? I am trying to keep with 87 octane if it matters. Thanks again.

Hey whackem04,

Your tune is not really very safe; you are commanding ERQ= 1.0 at upto 90% TPS - this is very offen >95kPa MAP (effectively WOT)

I'd suggest following the notes in the CALC VET Summary (http://forum.efilive.com/showthread.php?16280-CALC-VET-Summary-Notes) thread.



III. CALC.VET Tuning Tips

1. B0701: Disable Catalytic Converter Protection
Insures accurate stoich and PE mode/WOT Fueling

2. B0120: Change RPM Threshold for Airflow Calculation from 4000 to 400
Eliminates any Airflow Correction from the VE Table

3. B3308: Disable DFCO: Change B3308 (M6) to 140C Change B3313 to 140C
Accurate fueling computations

4. B4105: O2 Switch-points to 450 Millivolts
Smoother MAF & VE Table

5. B3618: PE Modifier Based on Rpm (EQ): 1.16
Safe adequate Fueling regardless of Fuel Type

6. B3616: PE Enable: make sure PE enables as load becomes significant
(e.g. below 60% TP below 3200 rpm, 35% TP above 3200 rpm).

7. B3608 and B3609: PE Delay: set these to zeros.


cheers
darcy

[whackem04]

So change the above run calc vet again and everything should be fine? I found Weatherman's base tune, should i start with that as a base and go from there?

[joecar]

I'm running way behind... it will be another day or two before I can look at your files...


+1 on what darcy said.


Do not run 87 unless your compression ratio is 9.0 or less.

[joecar]

B3608, B3609: set these to zeros.

B3616: set this to 60% below 3200, and 35% above 3200.

[whackem04]

OK i have a revised tune where i put the calc info into and did the above. Now PE kicks like it is supposed to. Trying to get the power right and idle in transition correct.
TIA for all your help and being a voice of reason

[joecar]

MAF BEN map looks good, hide low cell counts, apply transient filter, paste-multiply-with-labels into B5001.

CALC.VET map looks ok, , hide low cell counts, apply transient filter, paste-with-labels into B0101, it looks like the lower load area is lower than B0101, and the higher load area wants to be above B0101, but ignore the spike (flatten it out), then level out the reset of B0101 that wasn't hit to match the cells that were hit.

Then take another log, make sure to operate the throttle in a steady progressive manner.

[joecar]

Don't forget these:

B3608, B3609: set these to zeros.

B3616: set this to 60% below 3200, and 35% above 3200.

TIA for all your help and being a voice of reasonOk, MAF correction seems minor, VE correction only hit low rpm half of VE table...

apply MAF map (paste-multiply-with-labels) and VE map (paste-with-labels) and take another log... this time load the engine (use brakes), you don't need very much log time, just enough to get the higher rpms in B0101.

Drive safely.

[whackem04]

What is the hesitation or bucking feeling when the Torque Convertor is engaged at 1500rpms and little lower, not there when TC is disengaged. Also if i lower the desired airflow table does that help the idle hesitation from idle/run mode with this type of cam?
Thanks for your last reply i think ive got the pasting stuff down now .

[joecar]

With a cam, the engine might not like the TCC being locked at that low rpm.

Yes/no/depends... you will have to go thru idle tuning.


Just remember when to use paste-multiply vs paste, and always use the -with-labels.

[whackem04]

in idle tuning when i log MAF to ECT how do i apply those values to the desired airflow table? which paste? (Number 2 in Idle tips and tricks)

Look at the units of the map (g/s) and look at the data units of B4307...

they are the same unit, so use paste-with-labels.


( the only time you would use paste-multiply is with a BEN map )

( always use -with-labels, it locates the map correctly in the table )

[whackem04]

Is there any other meaningful maps that can be made while performing calc.vet ?

[joecar]

No, not unless you're logging KR to see where it knocks.

[whackem04]

I am logging KR and spark advance in my calc vet pids. I figured out how much throttle cracker, throttle follower and desired airflow affects driveabilty. Now just trying to work out the little bit of bucking when torque convertor locks down. Its nice have a big cam idle at 700 rpm. People just think you got headers HAHA.
Thanks for the help joecar

[whackem04]

I have lugging at low rpms when the TC is locked up. My question is there a way to get the tranny to shift 1 2 3 normal lockdown tc in 3rd for the 40 to 50 mph then shift to 4th at sya 55 and then have the TC lock up in 4th at 60? Has anyone had any luck with this? A4 with 3.42 gears

Has anyone had any luck with this? A4 with 3.42 gearsYes, you would edit TCC apply/release tables (for 1st, 2nd gear set the apply speed to 255, for 3rd and 4th gear set the apply speed to what you want, set the release speed lower).

[whackem04]

Anyone have an example of this in action that works? I have big cam and tuned most of it out just looking at options. Thanks
