Volunteers needed for E38/E67 Calc.VET project.

not sure, I've never really checked recently. All he had me do was compare the values at 408kPa and add the multiplier and said that's all I need in addition to the other tables

Measure it because those values in the IFR table assume that this measurement is close to 400 kPa (58 psi).

Configured the my innovate MTX-L WB as below.

• Stoich @ 14.13 (E10 Gas)
• 10:1AFR@ 0v
• 16.8:1AFR@ 5v

github repo makes this a little easier for me, I hope thats ok.
I made some changes to the posted calc_pids.txt for the above WBO2 config, and to read lambda from my new CALC.WBV
I've also double the max frames to log in the scanner. However my laptop was not charged very much so I was only able to get a short log. please take a look an let me know if this is correct and useful.

Attachment 20800

p.s
I think this config was getting ~40 frames/second, up from I think ~9

github is a good idea (makes it easier to sync up and share).

*CLC-00-110

factor 0.5 1.5 .4 "iff({EXT.AD1},{CALC.EXT_AD1_WBO2.lambda},{EXT.WO2 LAM1})/{SAE.LAMBDA}"

This is ^ a pretty good good idea.


Your log shows LTFT's close to pegging positive...
( did you clear the trims after flashing...? )
( your the high LTFT's support the low MAF values )
you can create a map of LTFTBEN x MAFFREQ to adjust the MAF table and see if this brings the LTFT's closer to zero
( or more simply, just multiply the MAF table by 1.20 and start again ).


I see a problem with the pid CALC.TRIMMING... we may have to change it from "{SAE.LAMBDA}=1" to "abs({SAE.LAMBDA}-1)<0.001".

edit: if there is no abs() function, then we'll do sqrt(pow(x,2)) or iff(x>0,x,-x).

Switched the WBO2 lambda and custom pid to 14.7 since it looks like that's what the ecm is using.
Also scaled the MAF by 1.2 and reset the LTFTs as instructed.

LTFT's look pretty good now.

Let me analyze your log further, there are some calculations I want to check.

Thanks.

Well I got a reply from him saying we have to use 408 as there's no 400 on the table. What's the stock psi of these trucks anyway?

Stock rail pressure is 400 kPa (58 psi) gauge pressure...

408 kPa is very close (if you really wanted to you could scale by sqrt(408/400), but this value is 1.0995, i.e. 1.01, so you would not really see any difference).


You want to measure rail pressure to make sure it is good.

Thanks. Will be putting an order in for the Innovate fuel pressure gauge while I'm doing the transmission lines. It, just like the wide band, has serial output so I'm hoping we will able to also capture serial fuel pressure along with AFR as the guages are designed to be daisy chained

I'm a previous HP tuners tuner, having a hard time with Ben factors, and learning EFI, I still use hpt to log, and efi to tune. I didn't see any E67 VE ben factors or Clc.VE I found this thread Still need E67? I have a LH6 5.3L with LS3 cam, LS2 intake, long tubes, LS7 maf, 88mm truck TB, and running it with a 2007 CTS-v E67, mated to GTO T56. I have EFI live, Tuner Cat, Hp tuners, they are all licensed to this truck, so if you need to do any comparing between the three..could be helpful? I can run multiple logs a week. The VVE learning curve has got me banging my head against a wall. TC doesn't support that well. HPT 2.24 is the one I have a license too, and it doesn't support VVE either, so I chose EFI, really like EFI, its VVE is great, just the user here that isn't trained enough to tune the VE. Let me know if you want another Volunteer

[joecar]

Yes, E38, E67, E92 and any ECM that has a polynomial VE.


I don't remember if you're running analog wideband or serial wideband...?


BEN is simply = commanded EQR x wideband lambda

Sorry I posted this all over the board btw:( anyway yes analog through a/c port. Thanks for your help so far
