i just added a new 1000cc fuel injectors, fuel regulator, and 2 bar map sensor. I also moved the iat sensor to the intake. I'm using the default settings in the 2 bar os map sensor settings which may be the issue.

what injectors and did they come with GM data that you used to modify the tune?Originally Posted by smasher
Log?
Injector part number?
Injector data?
Map part number?
Details of what you are working on?
Fuel pressure?
Fuel system setup?
etc
etc
etc
GM 19418808 map sensor
1000cc (100 lbs/hr at OE 58 PSI fuel pressure) FIC Fuel Injector Clinic Injector IS304-1000H
58psi constant
starts with gas pedal applied but won't stay running for a log
408 tune by sirius just made some modifications to it.
Log without it running can say a lot. A log that you can keep running will say even more.
runs really rich
MAP sensor is pegged at 105kpa, that is a big problem.
Also you'll need to switch to the 2 bar MAP channel to log it correctly.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
can i put the 1 bar back in there to see if that will solve it without issues?
19418808 is a 1 bar sensor. Linear/offset of 94.43/10.33.
that's strange I was told if it has 2 rows of numbers it is a 2 bar. ill order this one 19418810 then it says 2 bar. thanks for your help

Never heard of that, sounds like bullshit.
Cobalt SS MAP sensor is 1 bar. Cobalt SS baro sensor is 2 bar. P/N 12615136 or equivalent.

Why would a baro be 2 bar? The cobalt ss map sensor is 2 bar, 90423637, and it's also a TMAP. Take advantage of that.
Wait a minute. I thought I already gave you good options for 2 bar maps? TMAP or IAT/MAP separate. With separate IAT get a 12615136. Linear/offset is 200/8.
Fuel pressure is setup for non-referenced. Is that the reg configuration?
Set Fuel>Transient>Min Fuel Mg to 0.005.

I bought an adapter to use the tmap but was concerned it leak, the adapter wasn?t really well made. I then thought about drilling it but then I was concerned with the way the oring was setup on the tmap that it would leak so I just dropped in a 1 bar I had thought was 2 bar and drilled out the egr spot next to the map sensor for the iat sensor. Ill adjust those configs and get a that map sensor. will the 19418810 not work or is the other just more commonly reliable? not sure if the injector info is correct I just plugged in what they had onsite. they didn't send any info with the injectors.

Squirrel is right. This is the sensor you want. Plug and play. No adapters, no cutting and splicing.
That's what it is.

2005-2007 Cobalt SS (the supercharged one, not the turbo)
Attachment 154335
And also not the NA 2.4L which GM also called SS for some years.
That's the same sensor PN we been using for nearly 20 years now.

12615136 ,and 19418810 are the same correct? It’s on the same chart labeled under 2 bar. It says 19418810 is the updated version of 12615136.
