Have to start somewhere though. Also the video above is best viewed in 720p for the correct scaling. Did anyone else get a recording?

I got a recording and watched it later. Gave me a bit to think about and loom forward to another one, if it happens

Re the bench testing.

Yeah I tested one of my customers looms and ECU I built on the floor, checked all the comms and had TP hooked up.
was very useful before I installed it at the customers house. Also cool seeing how the IAC operates in diag mode until the valve and spring went flying across the shed floor

On that subject, whats next for you with your coding? Any new model ECU you're working on?
Or happy to leave it at 12P and 11P? Or is it on a need to no basis? ☺

had a bit of a thought about this last night.

I know VL400 was saying lack of ram on the 808 limits features than can be added to 12P.

Wonder if recoding a version of 11P to be all manual to utilize the better hardware of the 424 assuming is has more ram? Also more inputs and out puts from redundant auto control lines.

Could be called 11M instead of 11P. M for manual

Oh and a couple of things from the youtube clip, it may have been discussed/answered by The1 though.

The offsets dick was talking about is due to the enhanced ADXs having a listen for header. TP strips these bytes so your payload offset changes.

Max RPM of 11P is around 11K RPM and 12P 14k RPM. The major code loops overrun so the ECU is playing catch up all the time, in fact the '424 overruns with a standard auto bin at normal operating RPMs. Its not a problem as it can catch up, with all the extra auto trans code it just does not have as much idle code time to refresh the RAM so quickly. To allow for some headroom this is why 12P is mapped to 9600RPM and 11P is to 8000RPM (all trans stuff is 8k RPM limited in 11P).

The1/Dick: I can certainly add enhanced to the custom ALDL message config in the flashtool.

Vlad: Send or post a log of 12P and the baro issue and I will take a look. There are no code changes in 12P to support the scaling when logging, it was all done in the ADX and it got a little messy (and confusing). 11P does it all behind the scenes. Baro going to 104kpa could be an ADX issue with the 12P method or its going to default baro due to the ECU losing its brains with a flat or low CCA battery.

yeah when its said 104 kpa it scaled correctly when logging, when it showed the correct baro kpa it does not scale it appears.

only ever had the 104 baro once you gave me the updated ADX, never had the issue before.

I got one of the logs that did it on my thread, as in it shows correct Kpa but scaling was wrong in the calc VE. If i copy the 95kpa column and paste it in the VE table, next log it needs adjusting again but other way( too rich). End up at and endless loop of tuning in the 95-100 columns

if I copy the 95 kpa and paste it in the 100kpa column the fueling is pretty much spot on next run.

Things are always being added to 11P, there has just been very limited interest in it and with the time it takes for a release am holding out until people are using it more.

Recent additions...
; Trans: Added configurable Force Motor Gain Max Current
; - FMCurrMax
; Added KnockCnt for ALDL - Clears the count on each ALDL frame Tx
; Fuel pump speed control via PWM
; Handle custom PSM patterns for engine code when determing if in P/N or gear.
; Added SpkCutDwell to Cal Area
; Created a Shift Torque Management
; Multistage Spark retard during shift and optional Fuel/spark cut
; Bypassed check of max rate of advance while in shift energy management

You can do this now, just turn off the auto fault codes. Main issue is the speed sensor, its a reluctor input only but use a festy conversion and that is sorted. It also does not (and wont) support ref angles less than your maximum spark advance ie camira modules are not really supported (can be fudged to work on a v8 though).

Looks like the scaling is correct, just that the calcVE histogram is still using normal MAP. It needs to use "Baro Compensated MAP". Is it the histogram you found was wrong with the copy/paste?

yes. the histogram never fills the 100Kpa column so I assume thats the problem.

so if your recording has The1's voice ? are you willing to upload ?

I too couldn't make it but would be keen to watch it
