Has there been another company to support us yet or other options besides Trifecta?

 

Negative. The computer in that car is not used elsewhere really and didn't make a good business decision to develop support when major tuning brands had other, more common ECUs to support.

 

Any way around using a different motor harness and computer? I'm not afraid to hack into my body harness to make things work.

 

You would need to swap to an ECU that is supported by your choice of tuning software. The ECU in 07-10 2.2L cobalts is supported by EFILive and HPTuners. I am unsure of all of the differences between the 05-06 cobalts versus 07+ other than the 05-06 models do not have a camshaft position sensor where 07+ models do. Hopefully someone who is more knowledgable can drop in and help.

 

With a 07 computer could you possibly just plug in the camshaft sensor and tune it out?

But doesn't the 07 run the timing off of it?

CBM said: "Delphi MEFI 5 computer and one of our custom harnesses" but it's 1500 for the harness and ecm and 1000 for the cable to tune it.

I wouldnt use one of those ebay kits unless youre sure of what ecu they use. The cavi ones are no good.

Im sure its possible to switch to 07+ electronics but youd need a different head.

 

I can't do that, have turbo cams and patriot head.

What does the cps actually do on the 07+? Could you just plug the sensor into the computer and zip tie it off somewhere and change its values to run right?

I also forgot the 07+ is coil on plug. Ughh

 

07+ models do use the camshaft sensor along with the crankshaft sensor for timing the rotating assembly. As mentioned, I would avoid ebay kits and the like. Your best bet might be to find a junked 07-10 2.2 to take the electronics and harness from it along with the cylinder head.

Your next issue could be the differences in transmission control. I am not sure if there is a difference; ie: a separate transmission control unit or is it controlled by the ecu/pcm.

Edit: just saw recent post. You might be able to get away with leaving the cam sensor unplugged and tune it out. Not sure.

 

It's not really an eBay kit they have a site. I just used it for reference.

 

I gave up on trifecta and am running an AEM fic8 on top of their tune

 

Awesome, that sounds promising. Your a 2006? Can you adjust timing? Is there any limitations doing this?
Mostly I just need to adjust fuel on top and timing, other than that it runs very well

 

Yes it will run without the cam sensor but you lose sequential fuel injection

 

You need to swap in a 07+ 2.2 ECU and BCM OR go full stand alone.
ONLY options.
AEM, HKS, MegaSquirt, Haltec, etc...

 

I think I'm going to contact aem about the fic. As I already have a trifecta tune that works without any problems besides it's not giving the full potential. A local shop to me is a aem dealer so maybe they can dyno tune it also.

 

you can only retard the timing with the fic you cant advance it and you need an FIC8 to handle the MAF sensor since ours is frequency based i wrote a how-to on installing the fic6 in an 06 cobalt almost 6 years ago, the fic8 is a little different if you decide to go that route than this may help https://www.cobaltss.net/forums/how-...g-fic6-217406/ if you go for that pm me and i will give you some updated info

 

My timing is at 20* wot so your saying I can't change that?

 

the fic can only delay the cam sensor signal (signal from the compression sense ignition) to make the computer ignite later

 

MegaSquirt can advance timing; you get complete control with it.


I tuned a turbo Tiburn on the FIC. It is easy, but limited.

 

yeah ive also looked into the MegaSquirt, at this point im convinced any engine computer is better than the E16A that came in our cars

 

Alright, I'll just deal with what I have already. This seems like too much work.

 

Joe, have you had to contact Trifecta lately? I've sent a few emails to them and Weller but never get a response. They no longer list our cars on their site so I think we got the shaft.

 

I haven't had contact with them since like 2009 I'll have it back running next week, I Just hope it Still runs.

I think they stopped when Vince left/retired.

If you need a s/c tune I think you might beable to flash somebody else's tune?

 

I thought about that but for some reason thought they were coded with the Vin number. I could check around I'd anyone has a L61 tune for a stock or 2.9 pulley. That is assuming the flash doesn't brick my ecu and I can flash it back to stock if it doesn't work. It's either that or f/ic8...

It was mentioned on here they stopped supporting it around new years this year. I guess that explains why repeated emails, Facebook messages, etc sent to both Vince and Steve have gone unanswered. Murphy's law it happens when I have a forged motor and supporting mods.

That seriously makes me question ever buying one of their tunes for the models they support now if they just drop you like that.

 

Exactly!
Another reason why HP Tuners is better lol

 

So out of the blue I received a FB reply.

If we were dropped I wonder how long before the others are dropped after something else comes out?
