Question:

A friend of mine want to buy a 3.2, I dont have the time to help him with the soldering so he is probably going to buy an assembled 3.2.

The assembled controller includes

* knock sensor interface (1 channel available on EC18 pin3)

* EGT sensor interface: not by default, but order AD597AR and ask (in order note) for free install. Also order K-thermocouple connector if you prefer to fit it to the end of flying loom compensational cable.

* currently no: ibutton interface

* 10 TO220 FETs default

* 8 TO220 IGBTs default

* DPAK FETs or IGBTs: on request

Finally soldered the inductor and fuse in on my GenBoard.

Made myself a serial cable and connected it to the board, powered it up with 12 volt and 0.5amp from my power supply.

And:

Nothing.

Nothing shows on bray terminal.

Checked the cable,its ok.

Shorted the rx and tx on the cable and checked the computer side of the connection. It's ok.

Measured 12 volt in and 5 volt out from the voltage regulator, ok

Checked and vcc on the mega128 got 5 volt so the board should have all its power...

Any ideas? What have I done wrong?

- Maybe swapped RX and TX, try swapping them ?

That did it.

Used Robs step by step guide, see now that it is for a female DSUB, while i use a cable and connect it directly to the serial port. the GenBoard/BuildProcedures/SerialPort page cleared it up.

thanks.

How do you enable both wbo2 sensors?

Suppose I have to configure both individually but cant seem to find anything on how this is done in the wiki/manual.

(Running a v8 with one sensor to each bank)

The same question goes to EGR.

I can't find anything about where to connect sensor #2.

Powered the board up and tried to check Pump Zero DC, its -3.2 volt!

Tried to change this in confix.txt and loaded it up but it's not changing.

Measured +4.05 volt on pump- (pin 7 on the econoseal 18) and 0.803 on pin 9.

Any ideas?

Your values in config.txt is way off. I see that you specify

<code>

wbo2_nernstdc_target=08

</code>

where i have a value of 0xA6. When i adjusted i mesured voltages across nernst cell (pin 13 & 18 in EC18).

* wbo2_nernstdc_target=95 -> Vnernst = 0,40V

* wbo2_nernstdc_target=E4 -> Vnernst = 0,62V

Your value for

<code>

wbo2_pump_pw_zero=84

</code>

also seem a bit high. I have 0x64 on my board, and it changes approximately by N*0.2Volt. So you should try wbo2_pump_pw_zero=65 or so, and mesure for 0.0Volt across Pump(+) and Pump(-) that pin 7 & 9 on EC18.

Anyway i think you should read the rather long WBO2 configuration process in the html manual, found in

[html manual section 4.2 wbo2] and make your config.txt more complete as 1.st step.

Also you can snatch another users config parameters for wbo2 as starting point, as i did. f.i. my parameters so far, that is working in my car is.
