Aisans own site lists 325ft/lbs of torque as the max rating for the tranny. As I believe it was 70Acc...something pointed out awhile ago in another thread GM is notorious for rating a transmissions max specs right above the output of whatever engine it's paired with in their own documentation and that seems to be the case here as well.

Did anyone else notice Fleece has oversized injectors available for the cruze on their site right now....

I am very interested to see how DuramaxTuner's twin turbo LML Duramax with all emissions equipment does in the long run. I think that will be the key to the future of diesel tuning.

Both my former TDI's were chipped, and it's a world of difference. It was astonishing how much better they were, and if you can keep your foot off the fun pedal, the economy's about the same.

I have two TDI's, identical from a drive train standpoint, one has been Upsolute chipped since maybe 2000 and the other is stock. The Upsolute car will give a gas VW 1.8T a serious run for the money and get better mpg than the non chipped TDI (51 versus maybe 47). The difference in response is night and day, I really have to be careful not to redline it in lower gears. It is really fun to drive, much more fun than the non chipped car.

If someone reputable made a chip for the CTD and the car was out of warranty, I'd probably go for it. You can also play with injector nozzles but as mentioned earlier, you can bump up against the limit of some of the mechanical bits at some point. In VW world, all that has been sorted so you know what combos are fun and what combos go boom. I assume the same will happen in time with the CTD.

I'm just wondering what it's like to actually have as much HP as a stock CTD to play with. I think my stock TDI is maybe 90 HP and the chipped car is 120.

It has been stated before, the Aisin will decouple the Torque Converter when its maximum "programmed" torque limit is reached.

Good thinking, but when I get a manual tranny version I'll not have that safety net and still have to figure out what's safe and what's abusive.

Not sure if anyone is actually following this thread anymore, but I thought I would just post another chip I found, just in case someone is reading it. It has three different settings, a 30 hp, 40 hp, and 50 hp setting. Has a warning that extended use of the 50 hp setting combined with many full throttle launches can cause more frequent DPF cycles and potentially even the need for a manual DPF cycle to be run. I don't know why, but I feel this is the best chip I have seen so far. Something about it feels the most comforting. Not that I'll be able to afford it or will I be buying one anytime soon, even if I could afford it, but thought others might be interested.

Theres a handful of threads on it. A couple members have it.

It is not a "chip". It is custom tuning and I have heard no problems with the people running it on here. This will be the besting tuning for the CTD. EFI Live has no competition when it comes to tuning GM vehicles.

I thought it was a "chip". The website says "The Chevy Cruze Diesel tuner comes loaded with 3 tuning options; a 30hp tune (see results below), 40hp tune, and a 50hp tune*. All tunes retain the factory emissions equipment and attain similar fuel economy to the factory calibration when driven in a similar manner." Doesn't that mean it is just 3 different canned tunes for you to choose from? I might be misunderstanding something.

It is a hand held unit that plugs into the car and tunes the ECM. It is also known as a Auto Cal in the Duramax world. They are not so called "chips" like people referred to them in the past. More like a programmer.

Sorry if this is a dumb question, but I just don't get it, so how does it work then? Do you get it, plug it in and do some data logging and then send the data off to EFI and they make you a tune and e-mail back the tune file and then you just copy the file to the tuner, or how does it work? Sorry, I just have no idea what separates this from a "chip."

In the "old days" they would physically remove the ECU (engine control unit) and either reprogram it or replace it. Hence the term "chip". Nowadays they can access the software (mmm, firmware I suppose) in the ECU via the OBD port. My understanding is that they download the program (the stock tune), revise it (the tuned, tune), and then upload the program back into your ECU, again via the OBD port. I had two Jetta TDI's that were "chipped" (i.e. tuned) and they were terrific.

Oh, okay! So I did actually understand how it worked I was just using improper terminology. When I said "chip" I guess I really meant "handheld tuner/programmer". So it comes with 3 different canned tunes, right? Like it isn't like I have to data log with it, send in the data to a tuner, and get a tuner to create a tune based off of the data, right? It'd basically be buy it, plug it in, select either 30 hp, 40 hp, or 50 hp tune, wait a couple minutes for it to reprogram the ECU, and drive away, right? Or am I still misunderstanding something haha?

So reading isn't your strong suit (j/k ) but I stated above that I have this tune already. You should check my build thread for details. Might answer some of your questions

Wow, nice Cruze!!!! I really want one of these tunes now. I'm going to hold out for a bit though. Now, this may just be my crappy reading again haha, but I couldn't see anywhere in there about whether or not a dealer would be able to figure out that you had tuned it, even when flashing it back to stock. Or when you flash it back to stock would it be like it was never there? Get's deleted without a trace. I have a 7 year bumper to bumper warranty and really don't want to mess that up haha.

Well, my dealer is very mod friendly. I have had modded cars since 2010 with my dealer, and never once have they tried to check my ECU.

The diesel ECU is encrypted, so there really is no way to hide the tune. You take a gamble with everything you do to your car, from updated suspension, to update stereos, to updated tunes. Chevy has such a good product, I accept the risk.

I couldn't of said it better about the risk factor. Driving is a risk itself. The 100k powertrain warranty says a lot of product quality. If vw didn't think they'd lose their ass they'd have 100k too I mean why not? Put your money where your mouth is.
