Hey everyone, looking for some advice here on a standalone engine setup. It's got a gm standalone harness for the engine and has a power glide behind it. It does have the vss sensor hooked up.

I have an LSA blower on a 6.0L and one thing I noticed was i always had a lean spike when i would tip in the throttle. It ended up being Injector timing related. Started playing with the the...

Got it figured out! Talking about the maf fail got me thinking and even though i had everything set to fail correctly, it seems this ecu takes a loooong time to fail the maf initially after a tune...

The tune was previously set up that way and had the same issue. I just changed it in this latest version to no MIL to give that a try with no change

Hey guys,

I'm have an odd issue going on where any time I load a new tune the car will start for a sec and die like the fuel is just getting shut off. The strange part is after 15 or 20 try's...

Hey guys, im trying to set up my project with a flex fuel sensor and having some issues. I am running an 05 van computer, drive by cable throttle body, 3 bar os, and attempting to get my flex fuel...

Still not having any luck here. Does anyone have any suggestions on parameters to log to get to the bottom of this? Maybe even a known working base tune for a similar setup I can compare to with...

Also we are considering hooking up a wheel speed sensor to the vss wires to give it some sort of speed input in case that is causing an issue

well we went through the torque management tables and maxed out pretty much every value in there. When you go WOT we still get the same result but we have found if you give it about 1/8 - 1/4...

Good call! Check that and noticed it was set to 330lbft at 3000 rpm. Which coincidentally is what the torque would max out at when we logged the engine torque. That table says it will default to...

Hey guys, I am tuning a 2011 silverado for a friend and i have limited gen IV experience with this type of setup. Quick background on the truck, its a 6.0L/th400 with an on3 88mm turbo. TCM is...

I am currently having the same issues with my genIII 6.0 and LSA setup. Mine has a lean stumble just off idle and quick throttle input while cruising. I am curious what you find.

I am going to...

big thanks to subeone over on performance trucks. He went through my file and fix a bunch of little things in my tune including increasing knock decay rates to max, zeroing burst knock, spark map...

Well i desensitized the tip in and rpm knock sensor tables by 20% and that didn't help. Also tried pulling up to 7 degrees out at wot (down to 15) and still had knock. I am really at a loss of...

Nobody??? Im going to try desensitizing the knock sensors by about 20% and see if there is any difference

Hello, I just swapped a cam in my 4.8L/6 speed s10 and i am having issues with knock. Previously, with a stock ls1 cam in it I had just been running on a stock 4.8L timing table with timing added...

I also need this done. Should i just note to have chris look at it?
