AutoVE how to for the LS2 E40 PCM using EfiLives AutoVE tutorial
Select PIDs for AutoVE
Note the following
4. In addition I select up to the maximum of 24 channels
GM.INVLVTMP_DMA Used in open loop commanded fuel maps
You must locate calc_link.txt file in C:\Program Files\EFILive\V7.5\Configuration and change in the E40 section Open Loop Fuel IVT Multiplier
B0141.COL=GM.INVLVTMP_DMA
B0146.ROW=GM.INVLVTMP_DMA
GM.APCYL_E40_DMA Grams per cylinder, used in Spark Advance maps
SAE.BARO Not much use except to record atmosperic pressure on the day
GM.ETCTP Used in PE maps
GM.KR Actual knock from sensor
GM.KNRETFinal knock retard applied, includes GM.KR and burst knock {B1914}
The following two pids can be selected in addition to varify the changes made to the AutoVE tune after uploading to the PCM.
SAE.FUELSYS (monitors)
STATUS A and STATUS B (bank 1, bank 2) = OPEN LOOP / CLOSED LOOP
and
GM.FSST (monitors)
FSST-SFPO SECONDARY FUEL PUMP ON = YES / NO
FSST-PEA POWER ENRICHMENT ACTIVE = YES / NO
FSST-HCEA HOT COOLANT ENRICHMENT ACTIVE = YES /NO
FSST-FTLA FUEL TRIM LEARN ENABLED = YES / NO
FSST-FPO FUEL PUMP ON = YES /NO
FSST-FCLA FUEL CLOSED LOOP ACTIVE = YES/NO
FSST-DFCOA DECEL FUEL CUT OFF ACTIVE = YES / NO
FSST-CPA CAT PROTECTION ACTIVE = YES / NO
Create an AutoVE MAP
Note the following
8. Select Engine RPM from the parameters drop down list
10. Open calibration {B0200} Main VE table
11. The following labels should appear in the Col labels field:
,400,800,1200,1600,2000,2400,2800,3200,3600,4000,4 400,4800,5200,5600,6000,6400,6800
13. Select Intake Manifold Pressure (kPa) from the parameter drop down list
14. The following labels should appear in the Row labels field:
,15,20.5,26.3,31.8,37.5,43.1,48.8,54.4,60.0,65.5,7 1.3,76.9,82.5,88.1,93.8,99.4,105
Repeat process for BEN_LC12. Is it possible with dual LC-1 to perform AutoVE on both banks at the same time, ie half the time to log AutoVE average the results from each side for GMVE
Set up Open Loop, Speed Density
Note the following
3. Open calibration MAIN VE TABLE {B0200} + 5% (for stock set up)
Open calibration MAX VE {B2030} + 5% (for stock set up)
4. Ignore
5. Open calibration {B2407} DFC0 temp enabled high and set to 256 º C (enabled below)
Open calibration {B2408} DFCO temp enabled low and set to 256 º C (enabled above)
Open calibration {B2403} DFCO airflow enabled high and set to 8192 RPM (enabled below)
Open calibration {B2404} DFCO airflow enabled low and set to 8192 RPM (enabled above)
6. Open calibration {B3618} PE Mode Commanded Fuel and set to desired AFR across the
board (EQ = 1.13)
7. Open calibration {B0146} Open Loop Inlet Valve Temp Multiplier for Open Loop Normal
Commanded Fuel in Gear and set the value of cells for all rows above 80 º C to 0.1 ensuring final
EQ value of 1 at temps above IVT 80 ºC. This probably isn’t necessary as when ECT ≈ 80 º C,
IVT ≈ 136 º C
8. Ignore
9. Ignore
10. Open calibration {B1508} Long Term Fuel Trim Coolant Enable above and set to 256 º C
Open calibration {B1509} Long Term Fuel Trim Coolant Disable above and set to - 40 º C
Open calibration {B1502} Engine Coolant Temp for Closed Loop and set all to 152 º C
Open calibration {B1504} Engine Coolant Temp for O2 Ready and set all to 256 º C
11. Ignore
12. Open calibration {B0804} Catalytic Converter Protection Enable and set to No
13. Ignore
14. Open calibration {C6002} and set {P0101} {P0102} {P0103} to No MIL
15. Open calibration {C0301} MAF Frequency High Fail and set to 0
Open calibration {C0302} MAF Frequency Low Fail and set to 0
16. Ignore
17. Ignore
18. Ignore
19. Ignore
20. Continue with instructions
Awesome
The easiest way would be to go to the sae_generic.txt file and add '_B' to the GM.AFR info for the Tech Edge or whichever WB you are using.
C:\Program Files\EFILive\V7\Configuration\sae_generic.txt
# Tech Edge WBO2
# ========================
*CLC-00-916
V 0.0 5.0 .1 "{EXT.AD1}"
AFR 9.0 19.0 .1 "{EXT.AD1}*2+9"
*CLC-00-917
factor 0.0 2.0 .1 "{CALC.AFR_TE1.AFR}/{GM.AFR_B}"
*CLC-00-918
V 0.0 5.0 .1 "{EXT.AD2}"
AFR 9.0 19.0 .1 "{EXT.AD2}*2+9"
*CLC-00-919
factor 0.0 2.0 .1 "{CALC.AFR_TE2.AFR}/{GM.AFR_B}"
Thanks for your help :)
I have updated the how to. Tried something similar yesterday with out success, using fuel system status pid, you can log OPEN LOOP, OPEN LOOP DRIVE, CLOSED LOOP status. I was still operating closed loop...
I hadn't made the changes to B1502 to disable closed loop, I had thought MAF failure would have prevented CL? I will check DTC's again to check MAF failure is being monitored.
Would this apply to E38?
There is an EfiLive Virtual VE tutorial available now for the E38Quote:

The main idea with any ECM and autove is to make sure you are in open loop with no O2 trims. The idea is then to make a map (with same x and y axis values and steps as the stock VE table) using the actual measured AFR or EQ or Lambda etc and work out the % error from the commanded value. Obviously if you mix metric with imperial things will go bad.
That gives you your BEN value which represents how far out your open loop VE table is. You then adjust your VE table, which should mean that commanded now more closely equals your measured values. The E40 has a standard VE table so I dont imagine things will be too tricky.
Its probably a matter of logging the right PIDs, back in the old days you had to create your own calc_pids to chew some of the stuff.
Looks like you only need be worried about table B0200
I see what you mean about the other stuff though. Are you saying IVT is being logged at 16*C not 160*C? If so email [email protected]
How far out is are your BEN's?
I'm abroad with work again now, I havn't managed to go open loop speed density with any certainty yet. I'm working on the theory side until I return and am able to have another go.
I was seeing 160 C in the dash board of the scan tool, but when i lookked at the tune tool table it was looking up the row for 16 C.
I did manage a couple of logs, i would post my SD tune and logs, i'm not sure how, is there a host like photobucket for pics?
Here are pics from the scan tool and then tune tool from a paused log play back
1. Scan Tool: IVT = 162 C , ECT = 93 C, MAP = 30 kPa
http://i5.photobucket.com/albums/y16...0112007668.jpg
2. Scan Tool:RPM = 2038
http://i5.photobucket.com/albums/y16...0112007669.jpg
3. Tune Tool: IVT = 96 C, ECT = 20 C both incorrect
http://i5.photobucket.com/albums/y16...0112007670.jpg
4. Tune Tool: MAP = 30 kPa correct, IVT = 16 C incorrect
http://i5.photobucket.com/albums/y16...0112007671.jpg
5. Tune Tool: RPM = 2000 correct, MAP = 30 kPa correct

why are we still told to set PE to 14.63?Quote:

just my opinion of course.
I'm new to this, as far as i am aware there are two areas the PCM looks up to determine commanded AFR, PE and commanded open loop, which ever is the richest, is the AFR used. By setting PE to 14.63 means that it is ignored and the open loop map is used instead. How ever, I have been directed to an HP Tuners how to for the LS2 which says to set the open loop commanded AFR to EQ 1 and PE to your desired AFR.Quote:

you don`t want to go road racing like this.
Bear with with, I understand where you are coming from now, from the table below PE is enabled at increasingly lower TPS values as RPM increases above 3070 with higher EQ values, and where map values are low.Quote:

Hence Alternative how to sets the PE to EQ1.13 at all RPM's and commanded open loop to EQ 1, but doing that removes enrichment during cold start and warm up conditions.

8190 7.998658 1.219727
Sorry about the table, cant get it to seperate columns
This still leaves two options for setting commanded AFR, bearing in mind that in my recent logs GM.AFR_B reports the 14.7:1, the PE commanded value not the open loop commanded value, during cold start when i know it was commanding richer and was running richer. Could be related to the bug I reported earlier. The BEN value is derived from Actual AFR/GM.AFR_B.
Option A: (EfiLive) Set PE to EQ = 1 and set open loop map values less than EQ 1.13 to 1.13 (running rich in all conditions, engine protected under high rpm low kPa, smooth AFR transition under all conditions, not good for cats thou??)
Option B: (Alternative) Set PE to EQ = 1.13 and set open loop values to EQ =1 apart from where enrichment is taking place during warm up (enrichment during warm up, stoich under low TPS, RPM and MAP, variable AFR's) Could lower the TPS/RPM threshold so that PE is commanded for all conditions??
From what I remember smooth AFR transition is required for AutoVE??
Be gentle lol
never set PE to 1. AFR%error gets calculated from AFRcommanded, thus it will account for non 1 PE's.

Use the attached cal_link.txt file which includes the B0146 link PIDs:Quote:

That means you must select the E38.INVLVTMP_DMA PID to get the link to work.
This file is part of the new 7.5 release that is being cut to CD this week.

I've seen this come up in other threads.
Should EQ values of 1.00 be used in the AutoVE process or does this onlt affect semi open loop in custom operating systems :help2:
Well my understanding is that EQ 1 is just a value to make everything consistent and reduce variations where adjacent cells command different values throwing our your BEN map.
You can equally well command 13:1 everywhere (EQ 1.13) though fuel economy will suffer until you finish your ve and return to more saner values.
The other guys are right, you dont want to be at EQ 1 under WOT conditions especially with FI.
I just used to command 14.63 up to 80kpa then 13:1 thereafter and AUTOVE to that.
You "should" be able to do that by telling PE to trigger on 80kpa and not trigger on TPS (ie set TPS trigger to 0% or 1% etc) and command 1.13 at that point up.
Hi, thanks, you misunderstood my I think? What I meant was if you command EQ = 1, the PCM will ignore the wide band and look to the NB and try to go closed loop. Setting EQ to something near stoich means the PCM will always be using the wideband?Quote:

I thought i had this problem sorted, when i entered the E38.INVLTMP_DMA for ****B0146.ROW unknown***** ii did not work, i wondered why i was asked to use the E38 pid when i'm using an E40 and i noticed that the E40 uses GM.INVLTMP_DMA, so I entered that, now its been a while i don't rightly remember if this worked or not.Quote:

I'm home in a couple of days, i'm determined to start the AutoVE process..

I was logging this pid SAE.FUELSYS to check I was in open loop
SAE.FUELSYS - monitors
STATUS A and STATUS B (bank 1, bank 2) = OPEN LOOP / CLOSED LOOP
I also logged this pid GM.FSST without knowing what it did and just discovered a wealth of information shown below
GM.FSST - monitors
FSST-SFPO SECONDARY FUEL PUMP ON = YES / NO
FSST-PEA POWER ENRICHMENT ACTIVE = YES / NO
FSST-HCEA HOT COOLANT ENRICHMENT ACTIVE = YES /NO
FSST-FTLA FUEL TRIM LEARN ENABLED = YES / NO
FSST-FPO FUEL PUMP ON = YES /NO
FSST-FCLA FUEL CLOSED LOOP ACTIVE = YES/NO
FSST-DFCOA DECEL FUEL CUT OFF ACTIVE = YES / NO
FSST-CPA CAT PROTECTION ACTIVE = YES / NO
Can't change it as it's read only. How do I change this? I try to change this in properties, but it always reverts back to read only! Maybe I'm just tired and frustrated! Car didn't run so well tonight.
anyone have an auto spark excel file? I tried to put one together like in the tutorial, but my excel skills fail me.
Will this ever be made into an "official" tutorial?

My initial results from this process are very encouraging, not perfect (YET), but better than anything Ive done previously chasing my tail using the stand alone AutoVE and MAF calibration processes.
Very interesting and I hope that works out... I don't have an e40 I'm actually tuning my friends GTO. I just want a tried and true way to make it right. When I get more advanced at this stuff I'd love to get into trying more things. My car is a 98 ls1 and I like messing around with it and seeing what new tricks I can do. But when I look at all the tables and whatnot for the e40 (2005 GTO) I get a little confused much like when I first started attacking the ls1 stuff. I think I have the tune for the GTO ready to do an autove. I would presume that I can do an autoMAF in the same manner as I would on my car? I don't think I'll need to at this moment but I'll cross that bridge when I get to it :)Quote:
