None of your photos show the engine ECU.
I've never worked on a new model Tucson yet, so I could be wrong, but I think the component highlighted on the photo below is the engine ECU :

I should reprhase the question. I need the plug that arrived at the motor FROM the ECU.....

 

They say a picture is worth a thousand words but it would be nice to have a few words to explain what's in the picture...LOL.

Anyway, it "looks" like you want to connect the race-chip harness to the fuel pressure sensor. I think that's the connector highlighted in your photo below. If that's the pressure sensor connector it will have 3 wires.

 

I think it plugs in between the fuel rail and the fuel rail plug?.

Gazza!!!

Or more specifically, it plugs in between the rail pressure sensor and the sensor's harness connector.

 

That could be it.. Thanks!!! I will wait for them to answer and let you know....

 

Would using a race chip void the car's warranty?

 

They claim no.

There is no flashing of the ecu, in fact there is no interaction with the ECU at all. So the number of ECU flashes is not changed.

From my understanding the only thing that can be traced are any warning messages that may appear mostly on first use until you find the setting that works for you. Also they could notice the power output difference but it can not be traced back to use of specific gadget...

That is my understanding from the tuning boxes way of operation. I thought before diving into it. I am happy with her but after one year i need that "wakening" that i could get from the +20-30 hp ....

 

This is My chip box.You need to unplug rail and plug in one harness from chip.Second harness from chip goes to that plug from rail.

 

So its this one. Correct?

 

skettchhhh!!!!

 

Yes

 

So everything worked as planned.

I did not have much time yet to test, only one 40km ride to open road to work.

I think you can certainly feel the car pushing more because of more torque. It feels that now it kicks in below 2000rpm from around 1.500.

Also all gears (especially 3,4,5) feel more "full" from 1500-4000 rpm.

Top Speed i think it has a marginal 5% increase, but i am not sure about that.

I am not sure if this is placebo. I have 30days for return. I will drive for 3-4 days and then test without it to really understand the diff.

I wonder if this is this how it is supposed to be...

 

My was on dyno before and after.
112ps and 140 after

 

I will try to verify mine on the dyno also, but did you see noticeable increase on top speed? or only torque and acceleration?

 

My top speed now is 200km/h.
But time to get 200km/h is shorter.
Car had 260nm before and 305 after.
