Hi All,
I'm working on an update to the AutoVE tutorial. One aspect that I am including are scripts to perform the needed modifications in addition to the written instructions and pictures.

Here's my first crack at the AutoVE script. Please take a look, test, and let me know if anything looks or works incorrectly.

Thanks in advance, see the following notes:


;****************************NA AutoVE Imperial Script Starts Here**********************
;This script modifies OS # 12593358 for AutoVE tuning purposes.
; * EQ ratios based on {B3601} = 14.681
; * All fuel parameters set to equivilence ratio (EQ) (EQ={B3601}/AFR)
; * All temperature parameters set in imperial (*F).
;
;The following parameters and tables are modified:
;{B3313} DFCO Disabled
;{B0701} COT Disabled

Good work. I might suggest additional comments to describe the applicable OS (year/model) for our dyslexic compadres.

I'm trying to make it as general, yet specific as possible. I'm testing now on many different tunes to verify functionality across multiple OS's. Thanks for the feedback.

You might include the few extra steps to do MAF calibration to complete the doc.

I have my VE "Express" .doc I could send you although it is similar.

On a 05 LS1 based truck PCM , E0102 and E0104 are the add line pressure for fault processing tables not E0103 .
E0103 is Transmission Failsafe Enablers , E0102 is Transmission DTC Fault Max Pressure Enablers and E0104 is Transmission DTC Fault Pressure Modifiers , which was what I had to turn off to stop harsh shifting during AutoVE .

Thanks, that was an fat finger error in the script. It should have been applied to E0104.

Is that the 1024k PCM? The 512k PCM's have E0102 also. Do I need to turn off P0101, P0102, and P0103 in both E0102 and E0104? I have no way of testing auto's so I'm going off forum recommendations.

Script updated, thanks for all the feedback.

That would be great Bruce, please send. I'm planning on including MAF calibration and going back to full CL. Any input or changes you desire let me know and I'll incorporate.

Did all 3 (P0101,02,03) in E0104 , E0102 (P01xxs) were already "Off" , so I just turned "Off" (P01xxs) in E0104 , yes 1024k PCM .

Thanks tunedbyGM! I was looking at some auto tuning threads by joecar and he states to turn them off in {E0101} - {E0104}. I looked at a few tunes and couldn't find any that had P0101-P0103 in {E0101}, so I modified the script to change these parameters in {E0102} - {E0104}.

Load your tune in the Tune Tool. Then go to main tool bar, Edit > Run Script. To see what was changed go to Calibration Window > Modifications tab. If you don't like some of the changes, revert and all the changes go away. If you like the changes, save the new tune with a new name.

Do you have your units set to metric? If so, you need to change a few things in the script to accommodate that. I'll post a metric version of the script later today to avoid confusion.

Do you think the B3605 example I sent you in my "AutoVE Express" is what is intended by:

If the calibration is displayed as EQ Ratio then set the values as per the red rectangle in this table

all the rows??

Your document shows consistent AFR's for each load column where the published tutorial states to only change the 80, 90, 100 columns. So, yours differs from what is stated. I think the bigger question is, which is more correct?

Did I get it?

You understand the question and I wonder which is more practical?

Cammed cars often idle rich, and as with idle timing, the resultant idle is more stable if adjacent cells are same or similar. Maybe jumping into PE is more predictable from similar values? I have tried several iterations and am unsure.
Then again, PE is a warm engine activity.

The AutoVE tutorial example B3605 is very different from the AutoVE ver1 example.

The AutoVE tutorial example B3605 is very different from the AutoVE ver1 example.

I usually set the entire table to EQ 1.0 and leave it there. This iteration, I don't see any reason to change the areas you'll never hit when tuning. As long as there is a smooth transition to/from these areas it's okay. The transition to/from PE mode is controlled by other modifiers that take some tweaking to get it really right. I hope the fuel dynamics Ross is adding into LS1's will help better tune the transition into PE. I hope this feature makes it into a near future release.

Concerning the idle on cammed cars, your so right. It seems that no matter what size cam they idle rich. I've been thinking about using an exhaust gas analyzer for setting the idle area, but haven't done that yet.

Good discussion!

B4205 is missing from COS3. It is the "Use O2 feedback when in open loop" parameter and is what allows you to be in semi-closed loop when EQ Ratio is equal to 1.0.

Aaron,

How is the FI script coming? If it is ready for trial I might be willing to be a test pig. I am putting a non intercooled Kenne Bell in my 04, 6.0L Escalade this weekend and have a preliminary tune set up. If it is not ready what do you suggest I change when I run AutoVE? Your thoughts!

Did this kit come with any sort of 'starter tune'? Just curious. I'm working the script and one area I'm a little stumped on is {B5913}. Looking at 'stock' tunes for positive displacement and centrifugal superchargers, the timing curves are distinctly different.

I'll have something later this evening but I'll need some feedback on how the timing tables work out.

Thanks for all the help. :grin:

I can send you a copy of my stock tune compared to what I have now if you like?
Timing is quite different.
It might be better if one of the more experienced tuners lets you know how they go about a 'stock' tune for FI?

The starter tune I received for B5913 is the same as my stock tune. I check a Radix tune from the archives and it was the same as my stock file.
