Alfa 2.0 V6 turbo

[MWfire]

Hy, my car has "speedo sender" on tranny. it has two pins.


Managed to get some info on alfabb forum:  "that the output of the speedometer sensor is a square wave of approx. 8V amplitude (I think it was), about 50% duty cycle, with the frequency picking up to several hundred hertz at 'high' speeds.

But it might be better to tap abs wheel sensor also two wire. It's 1988 bosch abs system similiar to bmw e30 or vauxhall...

your sensor acts like hall from gearbox. On abs are vr sensor.

Ok, i suppose i have it on abs vr?
Could you help me with connection info details?

Take a look on last few pictures i posted.

i connected 4.7 kohm resisotor between +5v and ps2-clk pin (1 and 4)

and 5.1v zenner between GND and ps2 clk  (pin 2 and 4)

Data pin 3 is free.
Everything is on removable plug. Should i remove something and add that 10nf between pins???

And also wich pins goes to abs VR?

bump  ;D

add 10nF, recommended.

If you use VR sensor, you will need decoder with  LM1815 chip.

between pin 2 and 4 (where zenner is)

I don't understand how then cable from shop would work on vr (does not have lm1815 inside.. )

vems is on the desk right now it has onley internal map connected and tps is rising slowley by itself as allways

i have been tweaking some settings and now i noticed that PULSEWIDTH is jumping to 30.6msec every second or so.

Is this normal, is something bad (too high PW ) is going to happen when i put it in the car  ??? ;D

[MWfire]

all normal. at -40deg car need lots of fuel for cranking.

thanks, that was quick.

On my old .msq PW stands still at 18.6 ms ?

Does anyone have some links where h[0] and h[1] tables are explayned

[lost]

-primary trigger vr 60-2 stock alfa
-alfa v6 fire order: 1,4,2,5,3,6
- using stock dizzy on last IGBT
- injectors are connected on first six outputs


Can someone re-check these "h" tables?

If i use six active coils in wasted spark (driven by three stepper outputs). How to connect them wich ones goes in pair Fire order for this v6 is 1-4-2-5-3-6    :-X

1-4-2-5-3-6

If fuel pump relay (gnd) is connected to igbt-ignition channel7, do i use 7 or  i7 ?? What's the diefference?

[MWfire]

only 7, not inverted

Thanks, it works.

Just adjusted TDC with timing light and with these settings it is spot-on.
Is this correct cranck min period for v6?



And i see that coolant temp and iat are +- 2 degrees off, if i correct it manually (ice and boiling water) and then upgrade to 1.1.70 is there a way to import whole config from .msq or just VE / spark tables?

Could someone please take a look at logs. Here is rar with megatune 1.1.47v2 my .msq and logs

Car dies after few seconds (i think after afterstart period) or when i touch throttle.
throttle is opened with screw at 2%, idle valve disabled.

When map is disconneced it works forever (forgot to connect it first time) :D

When using megalogviewer and opening vems msq and log i forgot wich lambda probe to choose innovative?
