To announce the release of "MS3 Pre 1.4.1 beta 1"
Who should use this code?
All users are welcome to try this code.

Main changes since 1.4.0 release
Bug fixes:
Fix to canin polling (from Jean.)
Fix MAFload calculation overflow.
3-step input blocks speed-based launch control
9 cyl COP gives config error on MS3-Pro. (untested)
Fix CAN passthrough problem for >256 byte reads.
Dual fuel pin only configured if DF on and switching mode.
Add some more error checking to CAN passthrough.
Flex does detect if the wire fell off and reports more quickly.
Fix (CL) Boost vs. speed VSS scaling factor x10 off.

New / changed features:
-

Minor / internal:
-

Known bugs
-

The firmware zip is available from:
http://www.msextra.com/downloads/dev/ms ... -1/beta-1/

Be sure to read the README.txt and RELEASE-NOTES.txt that are supplied in the zipfile.

Upgrading users are advised to enable the "old baro calc" for backwards compatability.

Some of the ini changes will result in harmless warnings when loading MSQs from 1.3.x
Users upgrading from 1.2.x or earlier codes need to pay more attention.
TunerStudio 2.6.x is REQUIRED.

Boost and 3 step works great. Thank you

Feature possibly, having a timeout function for the 3 step. I'm able to setup a 5800 3 step, do my burn out but as soon as I release the line lock and roll out to finish the burnout, it blubbers on the speed based limit. So maybe a latching timer upon release so we can roll out on the 3 step limit

Will try the MAF this afternoon and report back. Thanks James!

Good question... how about the 3-step mode stays latched until you release the throttle also?

That's a fantastic idea, using a user settable tps function I see in some logs, I back off on the throttle to like 70% for whatever reason, so I'd set it to 20% to unlatch. The auto LS car I'm about to crank up would really use that a lot

I wont be able to run this until next week i think
I'll be sure to check those canbus and flex pin fixes when i do.

[E30_Driv3r]

sorry for getting back late to this MAF bugs seem to be sorted out, wanted to turn up the boost more but my fuel system is in need of some checking out as i'm running lean, and I'm out of e85.

Hallo
my boost duty works not when Launch is on!
when the boost (map) goes over the Launch boost target the boost duty goes never under 74%!

I James,
I think is a problem with dual fuel and pressure correction, I have a 350 kpa sensor on the lpg rail is a absolute model
When running I have a delta of 110kpa from map and lpg pressure, this is set from my lpg pressure rugulator landi renzo
I try to see the value of fuelpress2 but I see is so very strange and wrong value, I try to use all 3 type of sensor on dual fuel menu gauge, absolute and differential
but for each type I have a wrong reading of real fuel delta pressure, in attach thr msq and the 3 datalog

driving my car around(coyote) and observing stumbles and power surging intermittently, i was able to spot vvt3 error flashing in ts that coincided with it, this is not easily repeatable somedays it does it not at all and somedays it is pronounced.

for troubleshooting purposes i swapped vvt2 and 3 in software(changed inputs, outputs etc, unplugged the actuators and tried getting them to sync, with offsets zeroed i had no errors but vvt angles were all over the place, i then started to adjust the offsets till i "zeroed the reading" indicated angles looked ok but both vvt2 and 3 error lights were flashing like a chrismas tree.

my thoughts on this are the code don't like the wheel decoder to be too far off offset wise.
vvt3 is the only one giving me fits and its offsets are in the 300 range, perhaps an adjustment in the code can fix this?

On dual table there are some bug,

1) Pressure correction not work, all type of pressure sensor selectable work out as expected

2) During accelerations all injectors are used, I have 4 for gasoline and 4 for LPG and during acceleration all 8 are firing

3) Fuel flow, instant fuel economy and all other stuf are look at primary fuel only, on second fuel show 0

like other my post on activation of dual fuel is a good idea to have the possibility to have a "AND" condition, if fuelpress is more than X and input is on then second fuel is allow

Also for may application is need to add extra fuel ( like the primary ) for safe the engine especially the valve, I look at many modern lpc-cng ecu and the use petrol injector

in case is possible to activate something similar? like staged injection? to activate only if appication is need eg turbocharged engine

Please post a datalog demonstrating these issues too.

a printsreen of 2 exsample, on lpg I have a negative fuel consumption

On tuner studio I can make a picture if you want to see what appens

Good to know is a old bug! but is strange I'm alone with this problem!
How work the dual fuel for the rest of people use dual fuel? maybe other people don't notice this?

could you please upload the source code with the CAN-fixes?
