My old 0-60mph vid

[Mr.Martin]

I was messin around on youtube yesterday and ran up on one of my old videos so I figured id post it. It had a pcm4less tune, aem intake, tb spacer, flowmaster super 40 muffler, no cats, transgo hd2 shift kit and ls1 fans. Tire size is 305/35/24.

I have 4:10 gear and detroit trutrack now and pacesetter lts w/ pacesetter y pipe and flowmaster super 44 muffler. Tore my old trans up so I replaced it but have not put the shift kit in yet. I will try and make a new 0-60 run this weekend so I can compare the gain... if any!

Get that crank relearn done!

 

[Mr.Martin]

What is that?

Nice!!!!

What is that?

Did you use your stock computer or have one sent to you? If it is not your stock computer, you need to go get the crank relearn done for your engine to run efficiently. You may even notice a difference in performance.

I sent mine in as a core so no it's not the original PCM. Brian seems to know his stuff over at pcm4less. It put down 320rwhp so I don't see how you can pull much more than that from a 5.3 with bolt ons and heavy wheels. I just got my updated PCM a few days ago so it feels a tad better now and no check engine light

with the relearn you could do better and have a smoother running engine.

Some tuners will turn off the CEL so you wouldn't know that you needed a crank relearn.....

The Crankshaft Position (CKP) sensor sends pulses to the PCM as the reluctor wheel teeth rotate past the CKP sensor. The PCM uses the CKP pulses to synchronize the ignition and fuel injector operation, and to time the interval between each CKP pulse. The PCM determines when an excessive change in crankshaft speed occurs by comparing each new time interval with the previous interval. A misfire causes an unexpected change in the crankshaft speed. A certain amount of acceleration/deceleration is expected between each firing stroke, but if the crankshaft speed changes more than an expected amount, the PCM interprets this as a misfire. The interval between CKP sensor pulses is extremely small. At high engine speeds, slight variations in the following components make misfire detection difficult:

Crankshaft
Reluctor wheel
CKP sensor
The PCM learns variations during the Crankshaft Position System Variation Learning Procedure. The PCM compensates for these variations when performing detect misfire calculations. Only a scan tool can command the PCM to perform the Crankshaft Position System Variation Learning Procedure again.
Perform the learning procedure after the following actions:

A PCM replacement
Any operation or repair involving the crankshaft, the CKP sensor, or the CKP sensor to reluctor wheel gap relationship
An engine replacement
The ignition switch is in the ON position until the battery is drained
