Scanning a tbss with a 408 and 2.3 ltr supercharger. Idles around 60 kpa. I notice it was getting lean starting around 3000 rpm if I held it steady and kpa was down in the 40s even dipped into the...

Just thought since it has a tune that's working, i could trim some time and steps by making a percentage change to the whole table
E67 pcm on supercharged 408. Friend dropped off to have a "look" and possibly go to a blended tune. I noticed pretty quick it smelled rich while idling but wideband was bouncing around stoich. Found...
Thanks 5fdp. That is the conclusion i came to as well. Was looking at this tune to do a maf tune vs the open loop sd tune it currently has. My question is since these appear to have been changed, how...
Supposed to be FIC1000. walbro 450
Looking at a tune file from a 408 supercharged trailblazer ss. Its open loop sd. The stoich is to 25.***. Anybody shed light on why? Truck runs pretty good om 93 octane. No major drivability issues.
This tbss is supercharged so keeping it a little cooler is pretty beneficial. Installed a 160* thermostat and adjusted the fans all that was allowed and is doing much better.
e67 computer in 07 tbss. Trying to keep engine temps a little happier. Doesnt give me an option for fan control below 192degrees. Is there anyway around this besides a seperate switch? tia
Looking at a 4.2 trailblazer. under torque management in has settings for etc related to fan overspeed. Can anyone shed some light on what its talking about? What is the "fan"?
[QUOTE=Daniel196;604114]It also seems that if I change desired RPM in the scanner in special functions while keeping the motor running there are no changes. Only other change I made to the motor was...
Is there a way to tell flex fuel and gears from calibration details or physically have to look at tune
as always appreciate it 5fdp.
tammy stock is the tune in the truck now. The other is stock from repository
I wouldn't think so. If you are mainly concerned with the engine side and main shift points/pressure those should be pretty much the same.
I don't have the two files you are talking about to see...
Dont have stock tune on my tahoe. Was wanting to put stock tune in for comparison but the ones i got from the repository have different ratios for the transfer case. is this going to create a problem?
Was wanting to put stock tune back in my tahoe for comparison. Went to the repository and downloaded a couple to compare. Same operating system but transfer case ratio is different. Is this going to...
Did you scale the injectors?
etc tps max vs mode is the table in question.
Please post the tune because the 05 Trailblazer stock tune I found in the repository doesn't have TC modes 1 through 11 like you mention.

05 Trailblazer 4.2. Looking for more explanation on traction control modes. I see a few tables under torque management referencing tc mode listed 1 through 11. Wondering if any body knows what these...
U have hp tuners>?
I appreciate you taking the time to make it so long winded. That was a great explanation. Is it or would it be beneficial to effectively lock out vcp to a set angle? I have zero vct experience. Also...
Anybody have any experience messing with the vct spark table? Wondering if it overides base spark table. Working with an 05 trailblazer 4.2.
thanks i appreciate it. The truck had 93 in it. On the vcp spark table what is it meaning exactly. base timing for that vct angle or is modified by that percent? Just trying to understand the table...
Can you shed any light or understanding on the vcp spark table. Says spark modification based on variable cam but I'm not sure what the timing numbers refer to. Numbers look to large to be a spark...
