I always use laptop, and I was having this issue even with much less than 24 PIDs. Will try BBL for the first time, and report.
Also, are we using V8 for scanning now? Or just BBL? Because I was using V7 Scan Tool.
Yes, I haven't used a laptop in my car for at least 1 year. It's been BBL since it was available.
Well it looks like I'm out of the market for a Cruze as my wife picked the 328i and we love the crap out of it.. Long story short - she broke her neck in December, got a C5-C6 fusion and wanted a "Halo" car in celebration of her recovery.
What sps rate are you getting with the 42 channels? I have always assumed it was a limitation of the chip in the hand-held and never tried more than 24 channels at a time. If I could get 10 sps or better for most PID's and run 50 it would be much better than swapping groups for different PID's when I stack it up with too many _M type.
Ok thanks, so could you guys please link a topic that helps you set up BBL or just give some brief pointers? I will also look for this info now and try to do it in the meanwhile. Does it require an SD card?
Nice little article today on the Verano at GM AuthorityQuote:

Doesn't need an SD card, but they are sooo cheap and you can store sooo many log/tune files...Quote:

but first download/install the latest V7 and V8 software from the EFILive downoads page, and flash in the latest bootblock/firmware, do that before configuring BBx.
Thanks Joe and Cindy!! :)
I have a 2005 HSV Grange and noticed the E80 tables in the tune. Is the flex fuel sensor a usable item with the e40 pcm?
Thanks
No, sorry, as far as I know FlexFuel was never finalised on any E40 applications.
That's a shame. So there is no listed pin outs or the likes even though the option to turn it on in the tune is there. What were the e40 used in before Australia got their hands on them? This model was only used here in a few cars of HSV with the cathedral port 6 litre from what I know.Quote:

The regular 5.3L TrailBlazers used the E40 in 05-06 as well, the Vette only used it for 05? (or 04-05, 06 started the E38).
Everything points to the E40 being a stopgap between the LS1 1MB with 24x stuff until GM could get the E38/E67 with 58x stuff out the door.
So I bought a Cruze yesterday and am gathering the stuff to do this to it and and have a question. What type of pins do the ECM use? Is it a standerd Bosch type pin like the LBZ use or something else. I need a couple, lol.
Also, I was setting up a tune for this and I don't have tables B0189, B0187, B0188 or B0186. Are these just not in my OS (12646746)? I DL'ed the latest version of the software yesterday thinking mine just might be out of date but they still not there.Quote:

My module is used to shift the calibration to allow for alternative fuels. I have this setup similar to the E38 ECM's as far as the flex fuel settings. I tested every pin in X3 and the Tech II always shows 0%.
I did not do a full flash
I have the car all setup for E85, Haven't put the injectors in yet, but I have them. Still don't know what I should do about these tables I don't have that Ross says should be adjusted. Any help???
Welp, injectors are in and E85 tables I have are setup. Used the injector data from a 2011 Silverado 6.0l E78 and it all seems to be working... V2 shows about 7.4% ethanol which is about right I would guess since I'm using pump 93 with up to 10% E. Guess I should put some more E85 in it and see what happens...
logs...
This is all I have so far, but didn't have ltft's set to log. Gonna get another and see where they are at. Don't have the WB setup on this car yet.Quote:

Well, I filled up the car with E85 tonight. Still had just under 3/4 tank of gas so only took 5 gal of E85. Took about 2-3 miles to get up to 27% E85 but took another 3-4 miles for the AFR to drop down to 13.12. So looks like I need B0187 added into my OS so I can adjust it to make the change a little quicker. LTFT are still a bit on the fat side at -10 to -15, so might bump the IFR table up a little to bring them down. Car seemed to run just fine though :D
Leaving to drive from Texas to WY tomorrow, so we'll see how the MPG is at least on this first tank. E85 was .79 a gallon cheaper then 93oct. :)
So any chance of getting B0187 added for my OS? Been running E85 for a couple weeks now when I'm close to the pump, but takes a while for it to change over in the tune once it sees it. So other then that, seems to be running good! :D
I just finished up wiring this in on my 11 eco. When I enable the sensor, it's showing 100% alcohol when I log. I've double checked that everything is wired properly. Something I noticed that I thought was a bit weird though, is that I'm seeing +5V on the Out pin on the ECM side. Is Pin 34 always going to be the one for the Alcohol out sensor line? Any advice or things to check would be appreciated.
I just threw my multimeter on the alcohol sensor output line after disconnecting it and I'm seeing about 8 mVAC at 57-60 Hz so it seems like the sensor is working.
Sorry to say, but the upgrade doesn't seem to work on the 2011 Cruze, exactly the same issue you have run in to, the ECM doesn't seem to read the sensor correctly.
So, what's the possibility of swapping in an ECM from a '12 Eco into my vehicle then?
I don't know how well that would work, other modules might not like it, but they are pretty cheap used, might be worth a shot.
Where can I find the actual terminals for the x3 connector?
I've gone the opposite route on our 2011 Cruze. Rather than add a sensor, I just activated the flex fuel algorithm and filled out the tables. There were around 15 I had to fill out. Will be testing over the next few days. Thanks for all the great info and what y'all do!
So is it safe to say 2012 and up cruzes are able to be fitted with the sensor and tuned just not the 11

Well I look at it like this, GM (or any car company) will save a dollar where they can, if the estimation routines were so good and accurate why are they fitting sensors again?
In late 2011/2012, the EPA decided that the flex fuel algorithm was not appropriate because of the following condition not setting off the correct diagnostic trouble code.Quote:

If the vehicle has the FFV algorithm, is running off E85, and has a vacuum leak, it will adjust what it thinks is the alcohol percentage to compensate (Stoichiometric AFR table references 40-70%), not setting off a DTC. That's why they went back to the sensor. Had nothing to do with the functionality of the algorithm itself.
Ouch! An expensive fix for sure.Quote:

Cost wise it worked out about the same, the car uses more on E85, but out here E85 is also about 20% cheaper.
My first tune got a 20% drop in mileage. Im testing methanol this week and then back to E85. I expect a 5-10% drop by final tweaking. GM can get 0% loss with E85 and their turbocharged 2.0L. Ill do my darnedest to match.
Confirmed? I've never seen a car get close to the 'test lab' fuel economy shown on the windscreen sticker.Quote:

I figured the high compression and turbo charging of the cruze would have yield a little less of a less of fuel mileage. If the cruze was my daily driver I'd be e-85 it but its the wife and she doesn't like the mileage loss
Unfortunately the EPA uses an energy multiplier for most of its E85 ratings, so you'll consistently see the 30% drop on the sticker as standard, rather than actual test results.
Buick Regal turbocharged, direct injection 2.0L has consistently shown 0-10% loss in fuel mileage.
The average losses I hear for an NA engine are 20-25% on stock tunes, we've attained 5-15% losses on average.
Many customers report 40% losses in their stock FFV trucks though, but I have not gotten to tune any of these yet.
