1.1.44 alpha released

[MWfire]

Any more info on setting up the dual config?

If you connect config switch to analog ch 7 than you use confswitch=199 for slot 0 and confswitch=215 for slot 1.
If you use analog ch 6 than confswitch=198/214

[gunni]

where are those information changed?

is the switch a 0v (off) / 5v ( on )

I think a little more outlined explanations are required.

When is confswitch=199 and 5V is on analog input(on vems board is pull up resistor) then is slot 0 activeted.
When you connect ch7 to ground(0v) then is slot 1 activeted.

Where is that changed?

I changed it in MT and after that next time I went into MT
the firmware was all of a sudden 16x14 STD instead of the 16x14 I was using.

Is this done in the config before uploading using the .bat files initially?
A little walk through would be appreciated

[MWfire]

Save your config(msq) with megatune. Make two copies. Open it(first copie) with wordpad or something like that and find confswith
change to this if you use ch7
      <constant name="confswitch">195</constant>
      <constant name="confswitch_bits">&quot;7&quot;</constant>
if you use ch6 to this
      <constant name="confswitch">194</constant>
      <constant name="confswitch_bits">&quot;6&quot;</constant>

Then open second copie(msq) and again find confswiht and change to this(for ch7)
      <constant name="confswitch">215</constant>
      <constant name="confswitch_bits">&quot;7&quot;</constant>

Now you have two config(first is for slot0 and second for slot1).
Upload first config to vems, exit megatune, change switch to short analog channel to ground(slot1), turn on megatune and upload second config. Now you can tune individual each config(slot0, slot1). But if you change slot you must close and start again megatune.

Excellent,

Thanks, now I just need to change my MCP chip and we´ll have double config.

Hi! I am testing the 1.1.44 alpha in my car. My car is fine up to 1600rpm. From 1600 - 2000rpm missfires/stumples it, than 2200rpm, it seems that it is ok?
Tried to lower dvell from 2ms to (1ms) and the engine is fine up to 1800rpm. Are now Running with 1.1.79 with the same fuel and IGN map with no problem. 

c004 signal-> coiltype, No. teeth=4, triggertooth=0, another triggertooth=1, toothwheel width=180, secondary trigger=25 and reftooth table=[0,3,2,1]

My mat table is at Tps 0-100% (120% -38c) (115% -18c) (100% 0c) (100% 20c)  (99% 40c) (97%50c)  (95% 60c) (93% 70c)

I have same maps for ignition,ve.. for 1.0.73 and 1.1.44. But now you have mat enrichment talbe(loock that table).

[GintsK]

And note other setting for angular width of tooth.

[gunni]

This would be the startup temp map biased from 20°C
It´s based on the standard temp/pressure to density ratio.

TPS can further from this adjusted for heatsoak situations.

Agreed?

I can't reproduce this lcd 1.xx lambda problem. Tested many setups, including MWfire's msq. Could it be some mystery interference problem? How long is your lcd cable? Is it shielded and shield connected to case from Ecu end of connector?

Slow lcd is explained by new task handling. Lcd is low priority task which is over ruled by higher priority tasks ( engine management ).

I tested .44alpha2 on real car. 4cyl 60-2 no camsync, Alpha-N. Wasted spark.

I note mentioned problem. It is present most of the time. 0 and 1 did not changing when needed.
Car previous ran on 1.0.73 with no any LCD related issue.

No other bugs noted.

I've tested 1.1.44 more today. lowered the spark to 20 degrees in 1500-2500rpm area . The missfires/stumples are gone. ? ?

Does anybody have any idea why this happens?

Were you testing the advance with a timing light?

[Arvid]

Were you testing the advance with a timing light?

yes. I have tested with timingligth at 1000-1500 rpm, seems ok.  I will test 1500 - 3000 rpm later.

[Sambas]

There is always possibility that your trigger type doesn't work properly in all conditions with this firmware. I can only do very limited testings.
