Terra's Adaptronic question thread, please help answer my n00b questions.

[TERRA Operative]

Ok,
I'm configuring a PWM high current output on my Adaptronic to control a pump for the water to air intercooler.

I want to set it up so that the pump runs at 25-50% or so (I'll figure it out when tuning) and to ramp up the speed to 100% with the aux temp input that will be used to sense the water temp from the intercooler.
I also want the pump to switch to 100% whenever the car is on boost, plus a delay to switch off.

Is this possible? I have set the output for the pump to 'OR' and am referencing MAP and the temp sensor, but how do I set the output to ramp up with water temp (it seems to be on/off) and to delay turning off for a few seconds when the car comes off boost?



Also, to make the stock idle speed control work, I have set PWM output 1 to Idle stepper 1 pulse, and PWM output to the same but inverted. That way either side of the idle speed control coils will see the opposite and the motor should move???

Is this correct? I don't think it is, has anyone done this with a 4AGZE or 3SGTE (they're the same) etc??





More stupid questions to come...

what current can that builtin PWM driver support. Am curious as to whether the pump motor might be a bit much for it?

[TERRA Operative]

3A inductive, 7A resistive. I can use a mosfet or the like to drive whatever size pump I want though.

With the 3 wire iscv you need to select "idle control" for both RSO and RSC.
RSC inverted and bothat 50% as you've done.
Idle stepper option is for stepper motor type control won't operate thepush/pull type iscv's.
I think 200hz is the frequency for those iscv's.

[TERRA Operative]

The stock frequency is 250Hz according to the documentation.

I had a look for the idle control as you said but I've only got the following available:

Idle Stepper 1 - Hold (normal)
Idle Stepper 2 - Hold (normal)
Idle Stepper 3 - Hold (normal)
Idle Stepper 4 - Hold (normal)

Idle Stepper 1 - Pulse
Idle Stepper 2 - Pulse
Idle Stepper 3 - Pulse
Idle Stepper 4 - Pulse

Idle Up
Idle Down


I assumed I needed the pulse one?

i have no idea how this would work. but i am interested in your results and how and if you get it to work as i would like to do the same.

I have another question in addition to the ones above.

I have been commissioned to install an adaptronic into a Jeep Cherokee with a stroked engine.
This would be an easy task if it were a pre update model, as I would ditch the stock ECU and install the Adaptronic.
However, it's never as easy as that.... This is an update model, so everything is can-bus..... The alternator has it's regulator in the ECU, the ABS, Airbags, Transmission computer and even the gauge cluster is all on the can-bus, so if I pull the ECU, who knows what will and won't work...

So, can I double up on some of the sensors in any way? I know I cant just connect both ECU's to one sensor, but is there a way to somehow link them together (a module maybe?) so I can have both ECU's reading the same sensor? The owner would like a direct swapover solution if possible.
If I have to run extra sensors, then so be it, but it would be nice if there was a way (we can do it with 0-20mA sensors in industrial process control, why not here?)

If not, I'll just have to install the extra sensors wired into his stock loom and have some sort of jumper plug to bridge out the Adaptronic when it's removed.

what firmware/software/ecu?
mine is current f/w and definatly has "idle control" available in the drop down for the 1-4 high load outputs, i saw it today.
might need to do the upgrades... features and improvements are worth it.

[TERRA Operative]

I did upgrade the firmware to the latest, and have the latest tuning software. I'll check when I'm back home after the weekend to be sure.

Abit of a hijack .

Ive just finished droping my freshly forged engine in my lux and iam running a adaptronic ecu. Problems is it need i to start it first start u right away other wise the bores will glaze over.
But i have a **** of a cold start map which was programed by a **** of a tuner. Is there any trick i can do to fudge the computer to think its hotter and start up? like change some values of some shit

[jzk25]

Fill the engine with hot water. I am not kidding.

[Tweak]

Tried that and als used a hair dryer on the sensors. Meh its on a tow truck 2morow and off to the workshop

Firmware - v7.0
Software - v5.0
ECU - v1.0

I found the idle control setting you mentioned. Once the patch loom is done I'll be able to get started on breaking things properly....

Oh, as my ECU was made 22/02/2007, is it likely that there are improvements to the hardware that would be worthwhile me sending the ECU to Adaptronic for?

The main thing a cold start is going to have more of is fuel. Your two options are to modify the sensor into thinking it's hot in the mapping table, or to manually adjust the overall fuel trim.

Unplug the water temp sensor. If no signal the adaptronic assumes 27deg c from memory. Go to corrections tab -> coolant enrichment low map. set it to about 80kpa. Then on the map at the wt 25 and 30 point add the percentage of extra fuel you wanna add.
This will get added whileever the sensor is unplugged.
I don't actually use any coolant temp enrichment besides adding a safety trim ramping up from 95deg c.
