2014 Chevy Cruze Turbo Diesel

[GMPX]

For what it is it goes pretty good. I wanted a manual bad but just isn't an option with the diesel Cruze. Its going to be hard to not tune this thing. For once in my life im going to have to leave something stock for an extended time.

I put mine back to stock for a few days, wow, they are dull , reflash, reflash, you know you want to.

As soon as they release a manual diesel Cruze I'll be down at the dealer ordering one.

I wonder if the no manual trans option for the USA has to do with emissions? As far as I know worldwide the Cruze Diesel has had both transmission options from the time it was introduced, as has the Captiva Diesel and Colorado Diesel, oh, you don't get those either

Malibu diesel became an option here earlier this year.

But with a locked down Bosch EDC17

I dont even think I have support yet do I? Besides if its like anything else that gets a new engine here in the states, they'll be bugs to work out. Which im sure my tuning could fix. Dome of these factory calibrations are scary. yes I agree, an E20 ecm would fit much better.

Probably more likely that automakers have realized most Americans are too lazy to take the time to learn to drive a manual.....

Not yet, it is in beta only, but it will certainly be out by the time your warranty is up.

The tune in our local Diesel Cruze is actually really good for what they are trying to achieve, GM could never release a Diesel car that has the wheels fighting for traction at half throttle off the line , but that is how I like it.
I think I'll take it in for its first service with the tune in it and see if they say anything.

I give GM more credit than that, they do it for a reason and I don't think it is because they don't know what they are doing, for sure it will be an emissions, warranty claim reduction reason.

yes I agree, an E20 ecm would fit much better.

I'm really liking the E20 now, fueling is done by a target AFR and because it is closed loop all the time I can just call a target AFR and it gives me the mm3 needed to reach that AFR, it is pretty neat. Plus it has knock sensors to adjust the pilot timings at idle to make them quieter.
I think it would make a great ECM for a 4 cyl Cummins.

They probably looked at how many manual trans VW Diesels are sold vs auto's and decided to scrap the idea. What is interesting is the rest of the world gets the 4T50 trans where the US Cruze has the Aisin trans.

With the auto trans, the car maker can more easily achieve 2 things here in the USA:
- increased fuel mileage (i.e. meeting CAFE requirements),
- reduced emissions (i.e. meeting CARB/EPA requirements);
they do this by upshifting early, by inhibiting particular downshifts, (and of course by applying the TCC often).

if so seems like it sure would make tuning easier for the experienced duramax tuners when this becomes available

Good stuff. Even the 1.4t Cruzey has the characteristics (powerband, trans. shifting) of D-max, I.M.O.

Both use a variant of the Bosch EDC17 series ECM's, so yes similar hardware and software, similar the key word here, certainly not the same though.

What trans. is in it? Is it stronger than the one in my car, and will it fit? LOL

A Japanese Aisin F40-6 with a non GM sourced TCM (ie, not T76 or T43)
