ok im new here but ive been doing this for years im a mechanic and i do every thing my self i will not pay for somone else to touch my girl

ok ive got the supercharge and intake for a real good deal 500 both off a recked ss and its going on my ls i have all puleys and idlers and the last one to day the generator relocation bracket i have a real problem now its the can on the side of sc it controls the boost i cant hook it up becouse of the sensor and my pcm cant control it is that right all so im skiping 200 and going to 250 with stage 2 at the same time and a pacesetter with 3in exhaust custom. back to the suject where can i get vacume for the can other wise im doing 2 things im going to hook it up so it builds boost right from start i know its hard on the engine and it will kill it its ok i have another engine or ill pull the can off and put a choke cable on the buterfly so that when i want economy its open and when i want boost ill close it what do yall think about this will it work like that or if theres another way please help im useing a service manual and the gm performance build book but somthings wont work like the throttle body mine is a drive by wire and the one tha show in the build book is the cavy style with cables and tps an iac all i did is bore the holes out to bolt up on the supercharger then there was a problem the throttle body would leak at the top and bottom so i took a piece of 3/8 solid aluminum cut a hole to the same size of tb and macthed the holes to the s/c bam fixed for 25 dollors and dident need no dam 1in thick spacer so now its time to wory about sensors im pluging the s/c inlet presher sensor and im taking the map from the 2.2 and putting it in place of the s/c map difference is 3 prong and 4 prong so with all the factory sensors unchanged only added the s/c what do yall think about this

buld cost so far

so far its 3200 for the kit with instation at the dealer i have 1470$ with stage 1 and 2 with custom 2 phase intercooler thats all by its self with a 4in1 pacesetter header and 3in all the way back so far my build cost not to bad huh

im going to try this next week on my vacation time i have days to make this work and all of yalls help. any info would be nice thanks

 

You need to be able to tune it...w/o a tune things are gonna be crappy and there is no HPTuners for the 2.2 yet

 

wicked good luck man i cant help ya tho this is too new haha i think u will be the first to have this

 

agreed with steddy, you WILL need a tune, not sure if hptuners does or does not have a 2.2 program... if not maybe a dealer can tune it for you, but hope it work out, this will be a major sleeper if it works!

 

Sounds like a great project but I think the tuning (or lack of) is going to prevent you from finishing. The ECM for the SS and LS are different so I really don't think the dealership can reflash it with the Stage tune and since HP Tuners doesn't work on the LS I think you are out of options.

 

unless u were able to put an ss ecm into the ls?

 

ok then does any one have a ecu and wiring harness for sale .. or can i put a wideband o2 with a pigy back e manage system and what about my can do you think is going to work

well im starting it all monday

 

there is someone who can tune but they send you a whole new ecm...i cant remember their name

 

you know, i wonder if the 2.2 can be reflashed for stage 2...and if it can, wouldnt that take care of his tuning issues?? jw

 

^^^Good luck getting GM to agree to that

 

the dealer tol me that he could try to flash it at stage 2 of the ss but he couldent say if it would take and if it would even stay. and there was no warnety and no money back. so if i payed for it and it dident take its my loss

 

so what about controling the s/c can manualy with a choke cable

 

Can't happen. The pcm's for the SS's and the 2.2's are completly different.

 

Westers garage. google him and im sure he can custom tune your car. or check out the site. there realy good. i had a diesel chip in my 95 tahoe and it did wonders for that old oil burner

 

^yep. the pcm in the ls cant read the boost from the s/c. it'll will see massive amounts of air coming in and try to adjust the fuel trim, which will probably max out the stock injectors. it will run like **** with the blower on it. the pcm's are totally different. i wouldnt even attempt to do this unless you had a ss pcm and harness.

 

Your wasting your time till a solution for tuning is out. Hold your parts for now or sell them.

 

One a week, every week....

Please refer to the following thread:

https://www.cobaltss.net/forums/2-2l-l61-performance-tech-45/l61-turbo-super-forced-induction-information-thread-26325/

You can not do what you are suggesting yet. The E16A ECM in the 2005-06 L61 Cobalts is not capable of boosted applications. The software does not support it. The MAP sensor is a single bar, and can't read it. You can't put a higher bar sensor in, because the ECM has no data for anything over 1 bar. You cant swap ECM's from an LSJ, they are not compatible. There is no piggyback. HPTuners doesn't support the E16.

Now if you have a 2007, you have an E37 ECM, and that is supported by HPTuners.

 

well thanks for the info and im doing this any way jut to see what will hapen and then ill just put a stand alone system on it if fuel is the problem i can fix that and i dont care about the boost solenoid i have other ways of making it work they may be redneckish but it will work

 

what about a megasquirt II system that would let me tune it plus more .

good idea or bad i know that all my factory gauges will stop working if i use ths

 

You can't tune a 2.2 in a cobalt, end of story. Refer to the 2.2 section. Megasuirt-no work MiniAFC 2.2-no work

The only way to "tune" a 2.2 in a Cobalt is completly remove the Control Modules. Then you would lose must every function in the car.


No offense but I dont see how Westers Garage can tune a 2.2 cobalt, its impossible.

 

You're going to "do it anyway"? Here's whats going to happen...

You will hit boost. Your MAP sensor will top out. Your ECM will stop sending anymore fuel. You will go super lean and burn the hell out of everything. OR, if you replaced your MAP with a 2 bar, your ECM will have no fuel maps for a MAP reading above 1 bar. Your fuel injectors will stop firing, and the engine will stall.

Then you are going to put in your standalone ECM. Here is the list of thing that will stop working on your car:

Your electronic fly-by-wire throttle
Your power steering
Your transmission, if its automatic
Your instrument cluster
Your starter
Your cruise control
So many other things it's silly.

Stop. Right now. Do not destroy your car. I am not being a dick. I am not trying to discourage you. I am telling you, from the point of view of a guy that has been researching this issue for a year now, you will ruin your car.

 

the westers thing was just a sugestion. someone on here said that the 2007 ECM from a 2.2 was supported by HP tunners right? could he just put in a 2007 ECM? he would have to change some of the pins on the ECM connectors but would this not work? just a thought don't flame

 

Well HPTuners is going to support the 07's after testing. They use the same ECM as another already cracked vehicle. I dont believe an ECM swap would work. (and seeing as its satruday dont care to look)

Not flaming the Westers thing but theres no way in hell Westers, or even Tune Time Performance can tune an 05 or 06 Cobalt 2.2. Its impossible at this moment. Somebody said Tune Time was doing a Tune on theres, they never came back.

 

The reason for the new ECM in the 2007 model year had to with the change of ignition system on the 2007 L61 engine. Previous engines used the compression sense ignition system which had no cam or crankshaft position sensors. It is mechanically very simple, less parts. Now in the 2007 year, they have gone back to traditional cam and crank position sensors with Coil-on-plug ignition. If the new E37 ECM was to be used, you would also have to use one of the new 2007 L61 engines. The E37 won't work on the older compression sense engines.

 

The PCM would cut ignition timing to prevent detonation (hence, you'll lose power) and you'll probably go into limp mode. This is all assuming the computer does this before you actually do detonate.

Also, you need to understand that the necessity of a tune or reflash is to support the bigger injectors that you would need at idle as well, not just at full throttle. Putting bigger injectors on without either turning down the duty cycle on the injectors or physically lowering the fuel pressure, you'll end up flooding the motor.
