AAN ECU extra connector pins - launch control - N2O - water inject

[ranz]

AAN ECU has 6 pin extra connector and the pinout is:

pin1 mcp3208 pin6,ch5
pin2 mcp3208 pin7,ch6
pin3 mcp3208 pin8,ch7
pin4 EC36 pin 34 (power out)
pin5 EC36 pin 36 (power out)
pin6 GND

First, I want to use launch control. I connect ground? to it over swich at clutch and extra activation swich.



I make the connection to pin1 mcp3208 pin6,ch5, now from the "input channel used" I choose 5?
What does mean the "Control range (shares with rev limit)?

Second, N20 control. Again, I connect ground? over switch to pin2 mcp3208 pin7,ch6



From "Input channel" I choose 6?
Now the N2O switch relay ground is connected to pin4 EC36 pin 34 (power out), what I have to choose from menus "N2O output" and "N2O channel"?
N2O output has 6 options - 1) INJgroup, 2) SPECFET, 3) I259, 4) S259, 5) P259, 6) Disable
N2O channels has 16 options from 0 to 7, and 0 to 7 inverted
And Minimum gear section. 1 is for any gear, but if I want to choose from 3 gear... I enter 3 as value?

Third, water injection. For that I connect water spray relay positive over switch and negative to pin5 EC36 pin 36 (power out).

Bot now, the same thing as with N2O control, just different window:



What I have to choose from menus "Output channel selector" and "Output channel 1"?
They have same options as i described previously at N2O section.

And do I understand it correctly that I can also use the pin3 mcp3208 pin8,ch7 as an output not only input? (also the other 2, pin1 and pin2 if needed)

And last... what for is used the pin6 GND?

Yes - inputs to ground - pin 6 in extra connector.

Range - same as rev limiter is not on/off - it increase spark or inj interrupts in configured range. usually 100...300rpms

Your additional power outputs are:
EC36-34 - I259 - ch2
EC36-36  I259  ch3
Low when active.

mcp3208 - only inputs! It is ADC chip inside board.

Gear is recognized by speed/rpm ratio. You have to configure it.

Hope this helps

Thanks, now it´s a lot easier to understand it all.
But do you know what for is the pin6 GND?

It is safer to organize launch and similar switches against noise-free ground coming form ECU than chassis.

It is especially important when you want connect some analogue sensor for dataloging purposes to VEMS.

OK, thats cleared now
Many many thaks

Little problems with the inputs.
pin1 mcp3208 pin6,ch5
pin2 mcp3208 pin7,ch6
pin3 mcp3208 pin8,ch7
They should be connected to ground (PIN6), right? but only ch6 and ch7 work when connected to ground.
When I tested it, I accidentaly discovered that ch5 works when connected to ch6 or ch7. Then I measured with DVM that ch6 and ch7 have 5V on them, ch5 does not, it´s not connectod to ground or anything.
Whats wrong with that?

Ch 6 & 7 can be used for switches where you simply ground the inputs, there is an internal pull-up towards +5V to enable this ease of use.

Ch 5 is reserved for analog inputs, any 0-5V sensors like MAP sensors or whatever you want, and this will not work if there is an internal pull-up to +5V as the sensor needs to control the signal directly.
