After more search I found tables of gearbox torque limit not referenced in HPTuners. My OS has 7 tables (6 speed + reverse).
And I was right on assuming that only the 5th and 6th gears where the...

Hi, thanks for the update!

I found these parameters in my ECU thanks to you, I attached a XDF file for these in case anyone's intersted. Should work on any 1.4T E78 with OS 12669508.
The front...

Thanks everyone for the answers!
I will take a look at the air piping and check if there's too much oil in there. Last oil change was done 6000kms ago (or 3800miles) with dexos1 gen2 oil.

I will...

Hi,
I'm tuning a 2017 Opel Corsa E running a 1.4T LUV/LUJ engine and E78 ECM.
The car is 100% stock except a flex fuel sensor and a wideband.

I can't get rid of the knock retard I'm seeing...

DFCO wasn't enabled, as shown in my graph the commanded lambda was fine, I finally got rid of these spikes in my graph by using the filter function.

[2142.156] = 0 AND [2142.156.slope(1000)] = 0...

Thanks, I tested your settings and it worked perfectly!
What I was missing was the TCS Max Torque.

Hi @sbarisic

Has your problem been solved since? I'm having a similar issue on the same car.
I noticed a lack of consistency in my WOT pulls and when this happens, Predicted Engine Torque Source...

Any news about this?

Discovered today that my CAN wideband controller wasn't logged in standalone mode. If this isn't going to be supported this should have been stated on the Pro Features or Pro...

Hi there,

I'm in the process of re-scaling the MAF and planned to do SD as well, 1.4T LUJ/LUV engine with an E78 ECM on a car with a manual trans.
I forced it in open loop, DFCO and CFCO turned...

A quick update about this, took some time to map the relevant parameters and it worked fine.
Didn't noticed any problem keeping the ECT stable with -1C outside, I will keep an eye on this with...

The data is there in the ECM but unfortunately, it isn't mapped by HP Tuners so you can't edit it.
However, if you have the user defined parameters feature you could add the parameters yourself and...

I'm relieved, thanks for sharing your experience! I thought there was something wrong with my tune :p

I did further searches and there is indeed a limitation to the desired ECT based on ambient...

Yes, it's the connector going to the engine wiring harness, the other light grey connector is used for the headlights.
I could have noticed my mistake if I had been more careful but what got me...

Hi, thanks for your reply.

Did some more research and found a unused space providing +12V ignition to install the Vcc pin coming from my ethanol content sensor.

Attached is where I put it,...

Hi,

I'm adding an ethanol content sensor to my 2017 Opel Corsa with the GM 1.4T engine and E78 ECU.

I'm looking for advices as to where would be the best place to get a +12V feed for the...

Sorry, that was a bad choice of word from me! I noticed in some conditions that the logged angle didn't follow the desired angle but the logged angle is correct in the sense of it's the actual cam...

Hm... I was indeed relying on the on/off flags but I guess it's not working/showing on VCM Scanner.
Oh by the way, unrelated but I know you're tuning an Opel just like me. Have you ever noticed the...

Hi everyone,

I noticed a strange behaviour about the desired coolant temperature setting on my car, 1.4T LUJ engine with E78 ECM (OS 12669508).
Here's the 18170 - Desired ECT table from my stock...

Thank you all for your replies and taking the time to explain your opinions on this.
I prefer staying on the safe side of things so I'll leave these settings stock and see if it ever gets in my way...

Hi,

I'm in the process of tuning my WOT fuel by using the power enrichment on a 1.4T engine with a E78 ECM.
I was thinking about disabling both catalyst and turbo overtemp protection once I'm...

Hi,

I'm looking forward at replacing the stock injectors for the same (0 280 158 279, same as yours except this the long version) on my 1.4T and the info available on the net about these isn't...

Hi,

I have a 2017 Opel Corsa E with the GM Family 0 1.4T engine and E78 ECM.
I'm trying to make the fans to come on after the car is turned off but it seems that the settings have no effects.
...

Hey folks,

I have a 2017 1.4 Turbo engine, E78 ECM and looking for some answers regarding tuning for E85 fuel.
I know the best course of action would be running a physical flex sensor but...
