Fix is to remove the 'KNOCK_THRESHOLD' parameters for Z32 as they were previously incorrectly labelled. They are applicable to other RB20 ECUs

Add to Z32_VG30_256_E.ADR to override base file (removing parameters)
KNOCK_THRESHOLD_MIN,&H0000,0,0,0,0
KNOCK_THRESHOLD_MAX,&H0000,0,0,0,0

As you can see, other parameters are corrected now:
CB5D : CE FF E0 ldx #$FFE0 (Filter map - high octane)
CB60 : 7B 80 82 tim #$80KNOCK_FLAG
CB63 : 27 03 beq LCB68
CB65 : CE F9 E3 ldx #$F9E3 (Filter map - low octane)
CB68 : B6 14 6A ldaa RAM_146A_RPM_DIV4_LSB

I usually use my own address files as there's lead time b/w Nistune updates, so I realign not so often.
I'm just realigning to 1.2.76 version adr files.

There're still some missing parameters and some misinterpretations:

KNOCK_LEARN_TP,&H7F74,1,1,1,1,Knock learn min TP threshold
#KNOCK_LEARN_RPM,&H7EFF,1,1,1,1,Knock learn min RPM threshold ==> this one is missing (OEM=1200rpm)

KNOCK_LEARN_TP is NOT "Know Learn Load Max" as stated in Nistune GUI but is Knock learn min TP threshold (OEM TP=48 so it makes sense, knock actions are not applied till TP reaches 48, basically it corresponds to the knock region in the timing map)

Thanks for these. I will add them now. I've been moving house/workshop over last three months so all development has been on hold. Finally finished setting everything up this week so good to go again

Ignore the naming of 'RHS' in the address file. Just text has been renamed inside the software
O2_VOLTAGE_RHS_LOW,&H7FA0,1,1,1,10
O2_VOLTAGE_RHS_HIGH,&H7FA1,1,1,1,10
See translation file:
ADDRESS_O2_VOLTAGE_LOW,O2 Voltage Lean
ADDRESS_O2_VOLTAGE_HIGH,O2 Voltage Rich
ADDRESS_O2_VOLTAGE_RHS_LOW,O2 Voltage Mid1
ADDRESS_O2_VOLTAGE_RHS_HIGH,O2 Voltage Mid2

Yeah, fine, but tell me where these appear in Nistune GUI ?
There are 5 params related to 02 in adr files but only 3 appear in Nistune.

Here are the O2 sensor ones.

Your FF92 (580mV) 'ready voltage' I have as 'rich trigger voltage'
Your FF93 (210mV) lean voltage I have as 'lean trigger voltage'

FFA0 (530mV) I have as 'Mid1 trigger voltage'
FFA1 (580mV) I have as 'Mid2 trigger voltage' which I assume is your 'rich voltage'?

I did not change the labelling from 'RHS' yet (only text fields) since I could not work out the exact function of these parameters.

This ECU has different O2 related parameters compared to than other ones I've worked with, and I know you have a more in depth working knowledge of this ECU of course :wink:

Other scales I've already shown in the previous post screenshot. Make sure File > Configuration > User Mode = Expert so you see all parameters

What was the fifth one I've missed?

Ok, got it, I added RHS in my custom adr files.

The functions of these params are these ones:

Code: Select all

DATA:FFA0 afr_const21:        fcb 53                        ; ...
DATA:FFA0                                                   ; O2 sensor minimum rich voltage (voltage threshold
DATA:FFA0                                                   ; below which the bank is considered lean if it is already rich)
DATA:FFA1 afr_const22:        fcb 58                        ; ...
DATA:FFA1                                                   ;  O2 sensor maximum rich voltage (voltage threshold
DATA:FFA1                                                   ; above which the bank is considered rich if it is lean)

DATA:FF92 afr_const20:        fcb 58                        ; ...
DATA:FF92                                                   ; O2 sensor "ready" voltage - O2 sensor won't be
DATA:FF92                                                   ; considered unless above this V at least once
DATA:FF93 afr_const25:        fcb 21                        ; ...
DATA:FF93                                                   ; O2 sensor lean voltage

The right descriptions in Nistune should be these ones:

Code: Select all

O2_VOLTAGE_RHS_LOW,&H7FA0,1,1,1,10,O2 sensor rich to lean voltage (rich to lean hysteresis)
O2_VOLTAGE_RHS_HIGH,&H7FA1,1,1,1,10,O2 sensor lean to rich voltage (lean to rich hysteresis)

O2_VOLTAGE_LOW,&H7F93,1,1,1,10,O2 Sensor leanest voltage
O2_VOLTAGE_HIGH,&H7F92,1,1,1,10,O2 Sensor ready for measure voltage
The fifth param was the feedback temp

Okay thanks. I've changed the address file entries accordingly yesterday, so will be next version. Got an older laptop to look at improving the scheduler to reduce slow down on older machines

I don't know if a "Intel Cherry Trail Z8300 64bit Quad Core 1.44GHz 2GB RAM 32GB ROM" Windows10 tablet can be considered as an old machine :roll:

My device is this one : https://www.gearbest.com/tablet-pcs/pp_ ... EVEALw_wcB

For sure, I'm experiencing sometimes some lagging issues

Had a look at the specs. Shared memory can slow things down when doing processing and updating graphics simultaneously. I see it here more frequently on my Acer particularly when running dual screen

With the freeze ups, what are the factors which make it more noticable? Is it only when all inputs (dual wideband and consult) are connected? Log playback too?

Normally I don't see any issues with stream mode and a single wideband input, or reported feedback from other customers

I've mainly noticed issues here on my older netbook with stream mode (Aspire One with AMD Atom), but not on my even older 2010 Dell Inspiron.

Fast playback on the log player will also hold things up until finished due to the number of updates but the number of updates (refresh events to each maptrace and gauge item per log line) are high in a short period of time (thousands of log lines). Skipping lines does not work well since it causes holes in playback data (as reported by Torque in another thread)

I only use this Atom tablet to record logs, so:

Consult on COM1 / stream mode / the maximum 13 data
Innovate 2 LC1 widebands + the former TC4 (SSI4 inputs) box on COM2 in daisy chain

Symptoms:
When connecting COM1/COM2 or the reverse, sometimes the UI hangs up for a while, typically about 10 seconds. Afterwards, the connection scrolling bars start to scroll and values are refreshed across the various panels already opened (i.e. Log recorder / Consult raw values / AFRs panel).
In rare situations, Nistune completely hangs up and closes.

I know :lol: I should have saved the crash report to send it to you. I promise I will do it next time it hangs up completely.

COM2 or the reverse, sometimes the UI hangs up for a while, typically about 10 seconds.
This part is Innovate MTS. Nistune calls the MTS DLL open function. At this point, the caller software (Nistune) will hang until MTS responds after the open event. This can also be seen when connecting sometimes in Logworks but I will try again to check

Sometimes when connecting, the freeze causes overrun from pending consult data (since the application is frozen by MTS, but ECU consult is still feeding consult stream data to the application).

Suddenly the application catches up and has a lot of buffered data to work through. That might be resulting in a data overrun and then crash as a result. It's a pain.... but need a crash dump to confirm

Best to connect MTS and then consult. However if you get a MTS disconnect and then reconnect that same issue... reconnect and it does the freeze up, and then the consult buffering problem happens again :twisted:

What I am saying is that the freeze is due to the MTS libraries called - which I have no control over since DLL open calls are blocking. I've seen it here on LC-1 connecting where it will halt everything about 5 secs or so here but I will run through the scenario to repeat.

From memory the MTS DLL calls cannot be made from a thread (non blocking, hence non freezing) and the pending windows event blocks all updates including the GUI itself
