Yeah the lack of response from Ken and James on your thread was rather telling, such a shame :(

 

booo. Well maybe you can share Ken the code and have him implement it? I'd really like the AIT corrections RPM reduction and the A/C idle target. I asked for the A/C idle target before the code was implemented, but they never implemented it. I also wanted a second "learned" DC% with A/C when using closed loop idle.

 

It should be dead simple on the MS3. "If target RPM<1000 when A/C requested, set target RPM=1000". The MS3 knows what the A/C is, the MS2 doesn't, which is why it needs a bit more work. I'm sure Ken can do it in less than 5 minutes for the MS3, he doesn't need my code.

 

And he probably will do it for 1.1... or he will get a lot of chat messages from me to do it in 1.11.

 

More firmware mods...exploring the stock 90-93 ECU has opened a lot potential!

PWM idle duty correction Vs system voltage. Switching on your fans, headlights, power windows, heated rear window and your RPM dips? Notice how the "Idle PWM %" gauge changes when "Battery Voltage" gauge changes.



And something "a few" people might be interested in...A/C idle up!!! I've assigned an input on the MS2 to read the A/C button. When it sees that input going low, it changes the target RPM to 1000rpm (if actually less than 1000rpm of course) and INSTANTLY adds 12% duty cycle to the idle valve.



Can't wait to try it on the car...sadly the gf's car battery died this morning, so I swapped in the Miata's battery so she could go to work.

 

funny. i add exactly 12% on my ms3x. can't remember the delay off hand, but it's the perfect number.


the idle voltage correction would be cool to have.

 

in order to implement this stuff, what stuff has been removed?

 

EAE IIRC.

Great job though Reverant!

 

Lots. MAF, nitrous, all non-miata wheel patterns, EAE.

 

Oooooooh. Nice. Perhaps you could include the antistall feature from the mario code? I've found it's pretty useful..and has taken such a load off my mind knowing that it's there

This will be available for the DIYPNP guys right?

 

There is no source code for the last few mario_b firmware modifications...

 

Unclear why stuff had to be removed... So far I've not seen any need to delete anything to make things fit, so what am I missing here?

G

 

what would removing everything we dont use do aside from make room? would it just burn faster for the most part, not make it able to actually run faster? im not sure how laggy it is in the first place but i thaught id ask atleast. i just notice ms2 when i hit burn when running makes a tiny hicup, where ms1 never did, like when stopping tuning in TS. maybe its just that im still on a serial cable who knows..lol...

 

It'd hiccup on MS1 too, you just didn't notice/remember.

Only MS3 'fixes' the hiccup.

 

The hiccup is inevitable due to the way the flash memory is deleted/written on the HC9S12. You can't just change 1 byte or 2 of the flash memory, you have to first delete and then write an entire page of memory - data which is used while the ECU is running, hence the hickup. This limitation is not there with the MS3.
