I remember reading somewhere that tuning on 07 have problems and issues? I wanna make sure because I'm planning for a tune tomorrow.

 

not sure about that...might be some minor compatibility issues...but i wouldnt think it would be anything major...i do know hptuners is supposed to be making and update here before long so maybe that will clear up any issues....and also maybe it would pay to check efi live tuning...theyve done a recent release so they may be good on the 07's

 

Im gonna have mine professionally tuned with HP Tuners up at Tune Time Performance in NJ. Apparently the '07 LE5's can be tricky, so im gonna leave it to the pros.

 

no issues with tuning the 2.4..im helpin cobaltcrusin tune his car with hptuners..its so far working out real good..got his idc down a lot from the maxed out inj...tranny is shifting real nice...car pulls real nice

 

^^ i can vouch.

Car is a whole new ride.

Can't wait to get a nice day to really open her up. And the day the track opens!

 

The LE5 engine tune is fine. I have noticed that between the 06 and 07's though on the automatic transmission there are some differences.

By the way: If anyone has a working 07 tranny tune could they shoot me the tune file

well the tune that cobaltcruisin is running..is workin fine on his 07 auto 2.4

 

well if you get a chance can you shoot me an email with his tune. the 07 that I have been working on seems like no matter what changes that I make it still will not shift at WOT he has to lift of the throttle about 10% then it will work. I have tried a few things and its beyond me right now

 

I did two runs yesterday with a setup and it did shift at WOT. I am going to run this tune for a few miles and illmatic3s and I will check the log. If that setup does indeed allow to WOT shift then we are in business.

But this has been our problem too red. Under WOT I've been have to lift 5% then back to WOT with the tunes we have been trying.

Our weather here in pa has been very troublesome. I am not able to get a clear dry stretch of road at all. It's either pouring down rain, icing, or snow covered.

 

ok good I am glad to here that I am not the only one that is getting the promblem. If you guys are able to get it to work and have a few miles under the tunes belt I would greatly appreciate it.

 

Well, HP Tuners software is what......like $500 or so? Plus you gotta have a decent computer of some sort. (All my posting is done via sidekick or on friend's computers)

Tune Time will dyno tune my car with that same $500......for $400. I'm not gonna say your tunes are any better or worse, but they are professionals at what they do, so if nothing else, I have peace of mind when my car is in their hands. And free re-tunes for life.

I dunno, paying $100 less for the same service, plus dyno #'s just seems like the ideal thing to do in my situation.

 

so it wont shift at WOT?....maybe ill just do the tranny tune first....and engine later

 

??? That is what we are doing. Working on the tranny first. Getting all the shifts to smooth and work out. There are soo many factors. My car w/ full bolt ons compared to his car with full bolt ons, both autos, so similiar but so different.

Good Luck w/ your tuning. Illmatic3s and I will keep everyone posted with our new findings.

 

yeah we got his car dialed in real nice...i wrote up 3 tunes for him to test and log...we got a lot of knock on the first 2...wel using 89 gas is a no no i told him..lol once using 93 no knock..hahaha. red...i know wut his car is doing..its the fuel that is messing up the tune..i sent him a 2nd tune..that has my modified stock inj tune with all the rest of my tune..and it he told me that 2nd tune it shifts like a monster..ill check this thread later...to work i go

 

illmatic3s
We still have shifting problems.... 1 to 2nd I still am lifting to get her shifting.
KRs are off from 2-3 shifts. I got the log coming towards your email.

 

yeah guy im not sure y he its not shifting..its def something fuel related....just cant figure it out...hmm odd

 

only problem i had with tuning a 2.4 was you have to do a "write entire" every time.

which is ******* annoying

 

yes u have to wait like 3minutes..haha just the thing with the 07 auto the car is not shifting WOT..very odd bro...any idea?

 

first thing you need to do is flash back to stock tune and see if it still does it to make certain its tune related.

then you need to take your current tune, remove all the rev limit, and transmission shift changes you did.

check again.

then slowly add back in your changes till you figure out which one caused the problem, and adress it.

 

I recieved my tune from Tune Time Performance in NJ. Great tune!

 

true smart idea bro..

 

Make sure you are scanning the right PIDs and scan. That will tell you what's happening.

Maybe coincidence, but there's only been two '07s noted with this shift problem.... and BOTH have the B&M kit installed. Just something to think about. Besides, unless someone knows exactly what the B&M is doing, they are just looking for trouble trying to tune the trans with HPT & the B&M. HPT can do so much more than the B&M anyway.

 

same promblems that I am running into with tuning the 07 automatic. sounds like it may be an issue with something hmmmm........

 

i wrote up a few more tunes for cobaltcrusing.to try out...hopefully it works..if not im gonna start with the stock settings and add more and more to the tune file..im not sure if he took it out...i told him too...sup bennyhhr...the shift kit cud b messin it up...ill keep u guys updated

 

I'm removing the shiftkit this evening. Although with this tune, the b&m is to the OFF position. But that isn't to say its messing something up???? The 1 to 2 shift will shift as long as I lift just a hair before it redlines.... So to me its not much of a problem since I've been driving 5 speeds before this automatic and I can do two things at once haha.
