he just bought a 2007 and he immediately bought the stage 2 and 3 for it because he needs the stage 2 injectors and other parts for the stage 3 to work.. so he'll still be needing his stage 2 injectors so ill defintaly get the right ones.. that is if i can find somewhere to tune or it wont be happeneing at all..

 

dammit the engine light came back on@!@#&$^@(*#$^

 

Did you ever tune the car?

 

yea man it happened after i got the tune

1st time it read rich, p0172
i couldnt read it with my buddy's cheapo reader this one

 

Lol, doesn't sound like you got a good tune. I have one that works just fine. If you are still rich then it has not properly scaled for the fuel injectors.

 

im sure they'll take car of it, im gonna call em in the morning
i know my car runs rich stock, but apparently not enuf to set a rich code

 

PM me if you need some help. I am sure the G5 and Cobalt are nearly identical.

 

apparently not, tuner told me he never tuned a 2.4 before and there were alot more tables to deal with

 

The 2.4L cobalt and G5 I meant, yes there are a ton of tables, no it is not hard.

 

So I just ordered the injectors and harness today. Is it alright to put them in without a tune or should I wait till right before i get it tuned?

bump

 

I hope you did not pay retail for the injectors. Please tell me you got them used off of someone here?!

You HAVE TO have a tune. There is no option about it.

 

^^^agreed, put em in when you're getting it tuned, or else you'll flood your motor with fuel and it wont start

 

yeah i got them off someone here (3ds138) okay so what exactly do I have to get tuned then because i have no idea and theres only like 2 shops around me that have dynos so im assuming that hopefully one of them can tune me up.

 

Oh Lordy! *holds head in hands*

DO NOT TAKE IT TO A DYNO SHOP TO PAY FOR TUNING! Find someone around you that has HPTuners, and have them adjust your Flowrate for the bigger injectors. That's all that really NEEDS to be done. From there you will want a tune that adds a good amount of timing.

With these Cobalts, I cannot stress enough.......do not go to a big time shop and pay out your ass for labor and stuff, when it can be done by yourself, or someone here. We are all here to help each other. The other guys are there to have you pay to keep the doors open. Usually the cost of tuning at a shop is equivalent to a Rent payment, atleast here in Arizona. Please don't spend a rediculous amount of money on this mod.

 

well my options are pay 150 for the shop here to do it or drive to queens ny (4 hours) for 06blackg85ss to do it (havent discussed price) or wait till may 12th when he comes up here to get it done.... im an impatient person so i prefer one of the first two what do you think

 

There was a thread that had people with HP Tuners post where they were at. You might check there and see if there is anyone closer to you.

Actually $150 for tuning is pretty cheap. You might want to double check the price by calling them and telling them what you want done. Most shops try to rake you over the coals.

 

Why can't you be in texas... lol I dont know anyone around here that will do tuning for a cobalt

 

Check this thread and the Frapper map link in the first post of it. There is a guy in Texas that has HP Tuners.

Do these just have an injector constant or are they like the lsj with a injector flow rate table? I haven't seen any calibrations for the 2.4's
Did you think there is any point doing this to a car with only a cold air and exhaust.
I can see bumping the timing but do these cars max out the injectors?
Thanks,C

 

yea my car was at 106% idc in 4th only mods were all gmmp stuff

 

There is no constant its a flow rate table. Really easy to calculate.

Stock cars are maxed out already.....thanks GM!

 

Psyko, I found my flash drive with my tunes on it. Still need the stock 2.4L?

 

It would help in your case so I can just do the compare file on your VIN and send it back to you already encoded with it so you won't need anyone else to purchase total year credits for HPTuners or do a compare file on your own.

Send away!

I should be able to turn it around really quick for you once I get it.

 

You've got mail

 

Harness is in! I will install it all tonight. I will also be retuning to allow the car to run the new fuel injectors without killing itself. from there, i will either tune myself, have DTP do a little for me, or use someone's tune, all depending on power gains and prices and such. Then again, I would really like ot see whats actually going on in HPTuners and how the car is tuned so I know what to do when I have problems.

Edit: kinda waiting on Stevo to see what he has come up. Any gain ideas my friend?
