E67/E38 additonal paramaters

[jsllc]

In working with the very responsive guys at HP tuners. I have these additional parameters found and added to the E67/E38 ECMs. Many of these will also work with others like the E40 and E92. I have focused on the ECMS that I most use and I have not tested and validated the other ECMs. These are defined in Beta 3.7.9.50 and later. Most, if not all, will not show in your OS unless you request them or until the software hits production. I have also identified and am working on the items required to adjust the Speedo for staggered systems.

my factory tune is setup for staggered front to rear if any of my info can help ? main thing i noticed is the front to rear error value is changed to account for the different tyre turns

I have also identified and am working on the items required to adjust the Speedo for staggered systems.

Would be nice to add some parameters for launch control. Obviously launch RPM but also get at the wheel slip limits and a filter or two if it's not over the top complicated.
I've had good luck adjusting slip with changes to VSS PPR:Revs/km ratio but it's a hack.

I have no idea how GM manages this or what parameters/tables are needed

[jsllc]

How about E38? Would like to see the EGR not monitored switch like EFI Live has. For those L99 to LS3 conversions.

i assume you are talking about {B1301} EGR System Fitted??

[ABADZL1]

i assume you are talking about {B1301} EGR System Fitted??

That sounds correct

[07GTS]

are there any idle airflow tables we cant see in E38..? like a rolling idle airflow minimum..? i swear there must be something because however i set up my idle airflow and get it spot on soon as its rolling (clutch in or out neutral) the tps always jumps up a few percent and spark tries to lower it but it cant and airflow cant remove it without going into surging event because its being held up by something alse, even with min airflow zeroed out still same

[GHuggins]

I've sent in some additional idle tables and then Scott sent in the same table request for me when it magically found it's way back to me somehow, but I never found anything referencing the clutch pedal in regards to idle corrections in any other software - not to say it doesn't exist... I can tell you that in actuality it may or may not have anything to do with clutch engagement, but instead have to do with DFCO or CFCO instead... It may also have to do with idle airflow being too low for neutral at certain rpm levels or be because your adaptive idle settings are too low for larger TB's or slower moving air through your TB due to bigger intakes or changed MAF cals (everything was calibrated from your original MAF cal, so how has it changed from that) - you can try multiplying your proportional and integral airflow tables by 1.4 or 1.5 - if the rpms are dropping too rapidly increase the left hand side of these tables substantially - you can also change the airflow limits of the tables (this can cause idle hang or slow self rise) - you can even set it up via speed settings to use adaptive idle whenever it's actually idling such as when the clutch is pushed in - adaptive idle doesn't kick in until less than 5mph...

I'm trying to have min TB percentages added to activate idle on top of other idle settings, but not actually sure these will help anything...

[07GTS]

sounds like ill try a little more been stuffing around for months now doing little here and there, even in just neutral soon as it see the speed signal above adaptive it raises (thought it was TB i ported too much but have brand new now same issue just not as bad) only setting i found to stop it was the "effective area max fail" but then when its too low it dosnt get the higher cold start, how do the integral idle airflow limits work is it the limit for the corrections or a boundary limit for any actual airflow ? my coastdown is low -5 and high 4 where as the normal is low -4 and high -5

[GHuggins]

07GTS - if your proportional and integral tables are labeled transition, normal and coastdown then your limits tables aren't correct - this is something I still have to get sorted out with the HPT's guys... They put the transitional and normal tables lower limits into one section "Normal" in the limits table - there are supposed to be three separate categories in the OS's that have these three categories whereas they only have two... I'll see if I can get this sent in this next week if I have a chance... On the one's doing this - it always seems to take a lot of fine massaging on ALL of the tables to get this sorted out and it's still never really "just perfect" - usually you have to do the opposite of normal "make idle correction more aggressive both on spark and airflow fronts then lower min air above 1200 rpms while keeping it progressing, but have min air below 1200 rather high"...

I'm sure there are tables in these OS's for clutch engagement - there has to be - just whether or not someone can read hex is nice enough to figure it out and send it in to be added is all it's going to take

[07GTS]

yea mine has the 3 tables transition, normal, coastdown, where from factory the normal is zeroed out in integral and proportional but i have just copied over the transition to the normal and it seems to correct errors a little quicker then if it were zeroed, i also found the transition only helps with a changing idle rpm so if i start engine and it idles 1000rpm then slowly drops to actual idle 800 it wont drop if the transition is zeroed till u give it a rev and it falls down to it so populating that get u to where it wants to be, ill have a play and see what helps and what dosnt with the limits table and i see what u mean bout all tables need little bits changed to all work together can spend many hours just testing changes

The responsive guys at HP tuners have added more that I identified. For those looking to fix staggered speedo issues on E67/E38 and others there new adds in the software. Still working on others. These are defined in Beta 3.7.1071 and later for the OS/ECM listed in the original post. You will have to request them for your application.

9054 - Driven Tire Circumference
9056 - Non-Driven Tire Circumference
5016 - Driven Tire Pulses per Rev
5017 - Non-Driven Tire Pulses per Rev
819 - Vehicle Speed Sensor Config
821 - 128K PPM Wheel Speed Output
823 - Drivetrain Type
824 - Vehicle Speed Data Type
15016 - Trans Shaft Speed Sensor

These were validated to be correct in version 3.7.1106. of the OS ver/year listed in the first post.

[GHuggins]

Were they able to get front gear ratio added in too Scott?

[jsllc]

Was not in my third or forth round list. I have my fifth list I am building and it is on that. Looking for some fixes on the third and forth list and then on to the fifth.

[07GTS]

just seeing how many of these i can get added to mine at the moment hopefully most of them suit

[07GTS]

do u have to read the tune file again after getting the update ? or should they just be there im just not sure i cant see any new tables just looking at an existing file, or maby none of them suit my OS (i gave them a list of all tables from this thread)

[jsllc]

They are just there. If you have an e38 or e67 they apply.

[gmonde]

you have to do a read with the updated version,, I yet have to try it ,,my car is currently in storage,let us know if it works

[ABADZL1]

I didn't. It was just there with the beta.

[DrkPhx]

Is there a CFCO spark exit table available?

[jsllc]

I didn't. It was just there with the beta.

If you have a 2012 ZL1 with the same OS it will just show up. Most others have to request at this time. All e67/e38 are supposed to get these by end of current beta.
