I dont know if GM Parts Direct ships to Canada or not, but if they do the harness is only $53 US on that site

 

Thanks for the idea, I will give them a call.

 

thanks for the heads up!

 

Regarding HP Tuners and how to tune for larger injectors, I'm a bit confused. Here is a link to the HP Tuners How-To on tuning larger injectors:

http://www.4cyltuner.com/Forum/viewtopic.php?t=5

According to that, all you need to do is change the injector constant using this forumla:

Injector Constant = Old Constant * (Old Injector Size / New Injector Size)


Is that really all there is to it? Earlier in the thread, Pskostevo said:

No, I guess that would have worked too, but I just calculated the Flow rate the good old fashioned way. 34/24=1.4166667 x all values in table.

Sounds like he used an inverse formula and changed many values, not just one.


Can someone please post up some screenshots and show what exactly needs to be changed in HP Tuners to tune the 2.4L for larger injectors?

 

There is no injector constant on the 2.4L or the 2.0L. That was used on older motors, you actually have to adjust an entire flow table. But the principle behind calculating the difference still remains the same.

 

Thanks for the clarification Stevo.

 

Well GM Parts Direct won't ship to Canada, but NewGMparts.com (Puritan Pontiac) would. It was $68 from them plus ~25 shipping, which will still be cheaper than local even with tax and brokerage when it arrives.

 

Good deal, junk yards are still a dime a dozen, but then again not everyone wants to go fight aids infested dumpster rats for injector harnesses.

 

AIDS infested dumpster rats > me

lol

 

does anyone have a harness for the stock 2.0 injectors for sale. im looking to add the sc injectors to my 2.4. would that work guys?? put on the 2.0 injectors and the harness with it it shouldnt have a problem after i tune it hptuners. how much for harness if anyones got it.???

Please read this thread. You need a special harness from earlier ecotecs. The 2.0L harness does not fit the 2.4L setup, and the 2.2L and 2.4L cobalt harnesses don't fit the 2.0L injectors. We have listed the specific part number you need.

Happy modding!

 

i put my ss/sc set up in today with the new tune from bryan herter....pcmforless.com
my car rips now def woke it up ALOT....so all you who say mail tunes are wrong, trying to get it dyno'd tomorrow, well today i guess its 430 in the am but hopefully ill have some numbers by later tonight...

 

is the part number 1541879 or is that for injectors i dont know how to search and find whatever that is. or you could just tell me where i could find a harness for those 2.0 injectors for my 2.4.

Read this entire thread. Every post. A few times.

 

Actually colbaltcrusin, I don't know where you could find out about tunes. I learned all my info from pyskostevo here in AZ.
Well I'm gonna let you guys in on a little secret. There is no special wire splicing or cutting needed. Don't even need to take out the electical tape. The special harness needed is none the less a 2.2l harness. Everthing is plug and play and I have to say the easist mode. Only took 10-15mins max. Then you just have to have it tuned.
I say $50 is a fair price. Our buddy is getting some for around that price. By the way the price for the 2.2l harness was $31.00 my cost. Don't know list price since I get employee discount.

I just returned from the Chevy dealer with my 2.2l injector harness, and guess what?

It doesn't fit my ss/sc injectors. The harness clips are much bigger than the injector fittings. I ordered GM part#1582220 which is supposed to fit a 2005 2.2l.

Again, this part doesn't fit, so don't order it.




So i can get the 2.2l ecotec cobalt harness for the 2.0 stock injectors for my 2.4 cobalt engine. gees that sounds weird for all that crap.. if thats what im reading will that work. so i read alittle bit the correct part # is 15411879. for the harness 2.2l for stock 2.0 injectors. now all i should have to do is put the new injectors in and that harness and then all my exhaust and intake mods and then take it to get tuned and should run fine correct.

No, it is not a COBALT harness it is a CAVALIER/SUNFIRE harness. Many people have ordered the cobalt 2.2L harness because they have not paid attention. It is specifically the part number listed in this thread. You are correct #15411879.

AGAIN DO NOT ORDER THE 2.2L COBALT HARNESS. :-) I have to strongly clarify that because people are confusing the matter.

 

so you think that part # is at the dealer under say a cavi from 04. cuz the # comes up for a 05 06 balt 2.2 and its the harness?? do you think it could have the same # but its different harness and for the cavi from 04 is that right. or where could i get one....

ryan.

 

yes 04 cavi/sunfire 2.2(ecotec) fits and works nothing older, anything older is all one huge engine harness. Lovethesox's car gained about as much power from the tune/injectors as he did from the header but thats just sotp/butt dyno. Dyno on monday @1pm!

 

So i have to find a 04 cavi harness with this part num that i have. gees i wonder if anyone on here has them... pffh anywhos let me know how that tune and stuff works and that dyno the numbers on that harness and injectors.

ryan.

 

I've been running the injectors and slight tune for a while and no issues. I dont feel very much of a gain after a while, but I think its also running pig rich. That wont matter soon though once I get my T04E in and put on

 

Got my harness, got my injectors, just trying to arrange some HP Tuneage with some friends of mine!

 

Does anyone know where i can get a tune, i live on the east coast of Florida!!!! thanks, i have a set of s/c injectors and harness ready to go

 

Was yours the one that had the injectors put in wrong?

 

hey stevo meant to say thanks the tune that you sent me i used it in conjunction with wickedss2005 hptuners and got him to unlock all the 06 2.4s and we put in the 2.0 injectors in my 2.4 and tuned her up and runs amazing. definatly have to dyno her and run it down the track.

Bumping up this thread for you 2.4 guys goin with the Rebel setup you are gonna want this harness
