Just curious if anyone has configured an output to command nitrous when to come on. The thing I want to do is command it to come on in a certain gear (say 2nd) in an auto.

Well, one thing is for sure.. outputs cannot be stored in the standalone interface. But heres something from the help.
"The device output control will operate relays, lights or a combination of both.
Turning on an output is configured in the scanner by choosing an engine variable or A/D channel and setting the conditions for on/off.
Please see the VCM Scanner Enhanced IO section for more information on how to configure these settings."
I'm sure it could be done. I'm just not so sure it would be 100% safe and exactly what the offset/delay is in terms of its output. Perhaps there is some lag.. Test the output using a light first..
Again, heres a quote from the help file:
"They can be used as a status indicator or external high current device control. NEVER use the interface to control relays where safety is an issue or vehicle damage may occur."
It also says 200milliamp max for each output. I am not too too familiar with wiring. Just trying to help out; sounds risky. Good luck.
I know how to use it, I have used it several times. It is not a question of how its used, it is who has done this and how did you have it hooked up. I do not have nitrous so I dont know the specifics on hooking signal wires up.
I have used this and it works great!
Output is set for above 90% TPS and 3000 rpm, wired to negitive side of relay and 12v to positive side.
Much better than a microswitch on a flimsy mount! And a free window switch!
Should be easy enough to only apply in 2nd gear.
I have had success with this "code"
Enable trigger
[SENS.90] > 90 AND [SENS.70] > 3000
Disable trigger
[SENS.90] < 90 OR [SENS.70] < 3000
Add in a MPH limit so you only enable in 2nd. My 2c.
...add in ability to monitor AFR, set a high disable point. Might have to figure out how to get around a momentarily lean condition when you first go WOT so you don't freak it out and cause it to go on/off/on/off/on/off.
So lets say I wanted to run a 2 stage hit using both outputs.
Would this work for a 2 channel / 2 stage set up for enable? (I'll edit with my disable once I figure it out)
Enable Chanel 1:
[sens.20] > 35 and [sens.70] > 5,000 and [sens.90] >98 and [pid.4120] = 1 and [aux.20121] < 12.9
Disable Chanel 1:
[sens.90] < 97
Enable Channel 2:
[sens.20] > 70 and [sens.70] > 5,500 and [sens.90] >98 and [pid.4120] > 1 and [aux.20121] < 12.9
Disable Chanel 2:
[sens.90] < 97
Sens.20 = vehicle speed
Sens.70 = RPM
Sens.90 = TPS
pid.4120 = Trans Gear
aux.20121 = AFR
This would also be wired in with a throttle switch, window switch and a fuel pressure safety switch.
Anyone???
Could anyone edit that with a proof ensuring that it wouldn't spray between the shifts in an auto?
The code I have up does not turn N20 off during shifts. I would still use a window switch or you would need to fine tune the on/off points based on either mph or rpm.
I would add in an upper RPM limit as well. Like below.
Enable trigger
[SENS.90] > 90 AND [SENS.70] > 3000 AND [SENS.70] < 6000
Disable trigger
[SENS.90] < 90 OR [SENS.70] < 3000 AND [SENS.70] > 6000
Too bad there is not line fuel pressure sensor. This could be a stand alone controler. But you can always add one and have it input to the cable.
