Default ismael_pt Adaptronic installation (DIY harness)

I'm currently making my own parallel harness and for now this is what i have done:

Routed directly all the wires, so is only an extension harness. Because is my first EMS and in order to make things easier I want to run the most simple parallel installation.

- Adaptronic: Fuel, spark, vvt, ebc.

- Mazda ECU: idle,fans,alternator, and the rest of simple stuff.


So, I removed injector and coils wires from the extension harness and routed to Adaptronic. Next step is sharing sensors between ecus.

I have a couple of questions...

Is the J4-3 (adaptronic) to 4D (mazda) the only wire needed to control VVT?

Do I have to ground all GND connections on Adaptronic?


I accept any suggestion.

When my simple parallel installation starts to work well, i'll deal with MAF trickery, launch control, boost by gear...

No answers for your questions here Ismael but; I'm glad to see you've started!

Did you get the DIYAuotune parts?

BTW; I like your plan of attack. Looking forward to seeing good results!

Not yet but next monday maybe. It's in the spanish customs now, crossing fingers to let it pass without taxes.

I guess that you plan to run both maf and map because you want the ecu for idle and the adaptronic for fuel?

The only ground that isn't connected in my loom is: sensorgnd.

Needs the mazda ecu a signal from the MAF to run the idle? Maybe I'll do the idle with the adaptronic, I want to remove the MAF.

I plugged the Adaptronic today with my ghetto harness. TPS, crank and cam signals are not working. I triple checked the wires and are ok. I can't figure what's wrong, maybe somthing about ground wires.

Logs are full of interference. Can take a look at it guys?

There is something wrong with your log files. Did you modify them? The columns don't line up like they should.

Are you using the newest WARI and firmware?

Could you post some new ones with out pututing them in a .rar file?

Ismael, follow roach's advice. You don't need to zip the file.

I think you may have a communication error between the adaptronic and your pc. The values in the plots you posted are not right. The trim can only have integer values, so 11.7 & 5.2 probably belong to a different column.

Is it possible to get a new log? You don't need to have the car running just turn the key on, then start logging.

New log, without modification of the file. I can't attach .cvs files, I need to zip them.

WARI shows this:

You have ground loop interference it looks like to me. You'll have to track down where you have multiple grounds for a single input source.

Travis,
I wouldn't try diagnosing sensor trouble just yet. Those logs are not right. I wouldn't trust any of the readings until you get the log corrected.

ismeal,
Try unplugging all of the adaptronic connectors except the main power connector(8-pin). Take a log of that, and post it. I'd like to see if the log is formatted correctly with just power and no sensors hooked up.

Another log, this time with only the 8-pin connector plugged in. Looks the same as the other logs.

BTW, the adaptronic reads correctly the IAT, CLT, MAP, but TPS, cam and crank signals are not working.

TPS ground is conected to senGND (4O mazda pin - A20 adaptronic ).

Is it possible this? If I disconnect the senGND, none of my sensors works.

What about the cam and crank signals? Where they must be grounded?

I have all my sensor grounds handled at the stock ECU. my adaptronic harness has the TPS GND removed from the connector and just dangling free. no issues with it that way. when it WAS connected, I had crazy log data. see for yourself:

With TPS GND connected at adaptronic (CAR OFF, not touching anything!):

Yates,
Your values, while crazy, appear to still be technically valid, integer=integer, decimal=decimal. ismeal's values aren't, he has decimals where there should be integers (Trim %) and integers where there should be decimals (Time).

This could be a ground issue, but there is also some sort of communication error as well. With just the +12V and chasis ground connected it should have output the default values for the sensors. Maybe a bad com port either on the PC or ecu...

I think your best bet would be to contact adaptronic and see if they've encountered something like this before.

update :

The problem is almost located. Something between the TPS GND and the other sensors GND, if I disconnect the sensor ground, all sensors stop working, and TPS starts to work, and vice versa. Where I have to connect the TPS ground? Or maybe I have to ground all the other sensors to a different pin. Currently are sharing the same ground point with the TPS.

BTW, logs still looks weird, but maybe is related to the bad ground.

You could try connecting one sensor at a time and see which one causes the readings to be off.

How can you tell that any of the sensors are reading correctly when they don't show up in the log? Does the live gauge show reasonable values that don't make it into the log?

If you had the other connectors unplugged when you took that last log then the bad log data shouldn't be related to sensor ground.

Y8s has his going, maybe you could look at the connection sheet he posted.

Sorry, I haven't explained myself very well. The Adaptronic reads the sensors, but the values are incorrect ( MAP don't change, colant temp is +30 or -30 or something, TPS is sometimes 20-23% and sometimes 40-45% and don't even change if I move the throttlebody)
