So I've been asking around trying to find out when an electronic tunning solution will present itself for the E16 'Orphan'. Some vendors told me that there isn't as much pressure on the developers to tune for these cars because there is a bigger tuner market for the SS/SC and SS/NA drivers. So I'm hoping to try to summarize what has been said and what we know about a tunning solution for the 2.2

I'm likely wrong about some stuff so feel free to correct me.

1. A piggyback solution does exist and will work but don't expect to be street legal and prepare for a long night of wiring.
2. SCT and Diablo are suppose to be developing a tune for our cars which will both allow the user to store 3 tunes (e.g. street, strip, and stock). I've only read on these boards this solution will be availble sometime in July. Is it possible we can get confirmation?
On the SCT note, they are developing this solution for Garrett. The Garrett Turbo is out there already and can be purchased but there is a no tune solution at this time. There apparently will be a tuner kit soon.
3. Hahn is releasing a turbo setup with a one tune solution for the 2.4. They could produce a 2.2L package if the E16 was cracked but it is not.
4. I know very little about what HPTuners are doing for the E16 cars other than that they are doing some testing in Florida and are looking for 2.2L with a manual tranny. So there is nothing planned at this time for the automatic.

I've seen this all in another time and place. Same problems different vehicle. People spent years waiting for tunning for particular PCMs and it never presented itself. In the end people had to use piggyback solutions and other odd hacks. There is alot of confusing information out there about tunning a 2006 2.2L Cobalt. From my conversations with GM Techs there is no one out there right now providing reliable solutions that can support Turbo applications. Are the GM Techs wrong?

I've gone so far to look into what is involved in cracking the ECM. We'd need a J2534 fully compliant passthru device which I've been recommended to drewtech.com stuff. Apparently CarDAQ-Plus is the best on the market. From there we'd need to bring in all of the data tables and determine whats what. Apparently this is the longest bit of the process. Since I have no idea what data is usually changed I would like to know what data has been changed for other cars such as the SS 2.4. If the altered data tables were provided we could at least know what the experts had to tune on the 2.4. Certainly the solution would be different for the 2.2 but which data alterations were made would likely be similar (not in value but in variable). Once someone takes it upon themselves to do this and delivers a decent tune for a buyable product then a reflash can be provided to the public so everyone that buys the turbo can use the said tune.

In the past people had to mail their ECM to a tunner and have it reflashed or reburnt with a said tune and it was mailed back out to the owner the next day or whatever. Has anything been said from SCT? Will we need to drive to an authorized SCT rep and have them tune our car?

In the end I want to turbo this bitch before it gets old and I don't feel like doing it anymore. I'm really wondering how the Garrett turbo tuner will be and if I will see it before the end of the summer.

SCT's canned tune will be sold with their kit. However, to make that tune, they had to hack the ECM and edit the information. That ability will be available to tuner shops with SCT's tuning software. So even though the tune you would get from Garrett is pre-designed, you can still change it later at a shop.

However, I'm liking Hahns stacked approach better. Get a basic tune for you ECM to remove all of the limitations, then do the actual fuel and ignition tweaks on a piggyback. That way you don't have to use a tuning shop anytime you want to make a change.

I keep this thread up to date on this very topic:

A few more things I forgot to point out. The ECM is different in the 2007s than the 2006s. So this topic does not apply to the 2007 owners. The computer uses a 32 bit processor in 2007 but a 16bit processor in 2006. Don't try to figure out why GM decided to move to a 32bit over a 16bit for our cars. The hardware was likely cheaper to have assembled then the aging 16bit processors.

Hahns approach sounds better to me as well. They will provide a basic tune which should work out of the box and many adjustments can be made through a piggyback solution.

At this point though SCT is our best hope.


In your opinion Halfcent will the tuning be out in July like the rumours claim?

Halfcent

I have no idea. The "rumor" was spring, which has since obviously past.

I heard a rumor the 2006 SAI Cars may already have the e37 VCM. Can anyone confirm?

Huh?

rycobaltls22

I don't think anyone cares about us 2.2s...:-( lol j/k But does anyone know what's causing the difficulty in the E16?

halfj99

he was saying theres a rumor that the 2006 2.2 balts with the air injection into the exhaust manifold may have the new cobalt 2007's computer
year_______computer name code
05-06___________E16
07-??____________E37

i bealive the problem is...honestly nobody cares were kind of an oddity , our computer only had a 2yr run so there isnt as big of a market

Vin

I never heard the 2006's with SAI had the e37 PCM but I will find out if they do or not.

This should be easy to determine.

I've updated my thread in the Tuning section on the AEM Fuel/Ignition Controller. It should solve any problems tuning a 2.2 for boost and has just been released for an MSRP of about $414 according to their site. You can download the installation manual and a tuning tips pdf from the AEM electronics forum.

Thats exactly how the smt-6 works. ill let you guys know in about 2 weeks if the smt-6 can tune larger injectors without a problem.

I can't seem to find the answer to this anywhere but what exactly makes a piggyback system "illegal?" A friend of mine has access to all of the laws in my state regarding motor vehicles and we can't seem to find anything outlawing that type of thing.

Halfcent

It does vary from state to state. Here in Illinois, the system itself isn't illegal. But if it causes the cars actual emmisions to exceed standards, or causes a MIL / CEL, then the car fails emmisions.

I have the SAI, could I easily check for the ECM version??
