I am pretty sure its the same sensor used in the cobalt. Or thats what i been assuming all this time :)

got it working :0

Thanks, i thats getting things moving.

Yea i do have g/cyl in the Y headers.


I took the maff pids out.

i do have some histograms that have red stars? does that mean i have...

can anyone help me out :)

I am having issues with proper config setup for my speed density tuned truck.

Like my 1 config
Main Spark - Timing Advance

main spark vs airmass vs rpm open throttle

I only get values in...

can you add 12611938 to your list :)

Nozzles and what they are rated for and what they actually flow are 2 different things. It takes 4 times the pressure to double the gph output of nozzles. so you are a tad off on your numbers :)
...

i hate to say it but people are not real good about helping with injector info on here. Not even best guess etc.

On my 07tbss the person who tuned it just put 63.4 across all the tables with ...

Yea i made the mistake getting fast 57lb injectors. Could not find any info on them so i sent them to get flow tested.. There injectors didn't even flow within 5% of each other..

I emailed...

placing the iat after the meth is the best fail safe on the market. You can get pretty agressive on pulling timing if your temps get hot.

With figuring for meth injection you should call the company and ask them for the actually flow rattings of the nozzles. Most are rated at 100 psi with a 1/2" id feed line. But its very common for...

can anyone help?

The map sensor under the blower on the cobalts are 2.5 bar. make sure you have the right one.

Ok, i got my tune to finaly attach. 07 tbss has a 413 cid tf 225 head, VRX5 Camshaft 236/238 .601/.605 113 LSA Vengence who tuned it built the motor and has great rep on the net for knowing...

Anyone know of how to set the pressure delta psi /flow rate table by knowing what your injectors flow? I need some help.

well when it was tunned, it had the stock retunless sytem in place so i figured i need to change something. I also just curious how they came out with 63.41 as the number to be put in?

Mine look like this but its a 63.41 in all cells.
Not sure what i should have in it. Would it not slope some? This is on a tbss, it has dual 255lph pumps and does have an aftermarket return set...

I have always had issues with over fueling in my tune. It was tuned by someone that knows what they are doing. I was told that i should get them flow so i could get some numbers that mean something...

hmm and i was thinking about getting a maggy. Looks good

This is what i have for him. [email protected]

Yea, i have bumped into that after posting about it. I just want to get my o2 to not have a curve in it and be just a tad leaner.

Sorry i didn't put in the first post. This has a speed densty tune on it. There is no maff on the truck. I believe ltft are already turned off. When i drive around i never see a value from it. ...

No, its N/A atm i do plan on going forced inductin very soon. Trying to learn more about tunning before i go there so i don't blow her up. But i do have 1.5 dipp in my af and i from what i...

I have a tbss that someone else did a speed density tune who knows what they are doing and i have changed some minor things like air filter exhaust. Well my a/f has changed. Can i trouble someone...

Thanks, I guess that means i going to have to be patient :)

If you get to the point you need a willing tester let me know.
