^Gary - Do you have an hpt cable? Have you tried to do a read?

Usually try small steps. Went from 450mv to 425mv today. I'll have @ 40 miles on gas tonight.

Betting we could go quite a bit leaner.

I'm going to do some experimenting with lower timing closer to your curve and dropping the O2 sensor switchpoint a bit.

Still don't think there is a real way to add EV power currently but if we...

Uploaded stock 13. Not sure how long it takes to show up. It is nearly identical to the 2015.

Stock 2013 Volt 66976

Thanks for the responses. I'll get a stock 13 file added. (Really want to see an ELR file)

I spend a lot of time on the dyno. Was bored one night so messed with the volt. Didn't mess with any of...

Neat to see people tinkering. I have a 2013 and haven't seen a lot of info on tuning them.
Couple comments/questions.

- Why does your file have 2 cams enabled in VVT? Did the motors change? My...

Went back out last night. I hadn't quite maxed the individual speedo fields so went ahead and raised them the rest of the way. Speedo was actually sort of close.
Broke a driveshaft but the tranny...

Have a hummer with a 4l60 (lol)
6.5 gears in the diffs
4:1 in the transfer case
63" tires

Problem is the max settings in the speedo calibration is 253,000 pulses/mile.
The tire/gear wizard...

And finally the answer:

Doesn't matter what part it is or who you buy it from - measure and verify everything that goes in the motor. One of the pushrods was a couple tenths shorter than the...

Dug through all the wiring the audio shop did. There was one pink wire they stripped that was not an O2 wire. I did solder and heat shrink it though.

I ohm'd out the connectors on the O2 sensors...

The title made my day. I would say add fiber and coffee.

Reduce exhaust restrictions. I would start with decel fuel cutoff in the tune. You need a bit more fuel going through there to ignite in...

I'm trying to remember now. Its something like a 228/234 on a 112. Dual valve springs on the PRC as cast heads with cometic gaskets..

Pretty much similar situation as the two above. My split is...

After a fresh flash it should start at the high.... but should is a dangerous word.

Most will set the tables the same while tuning and then just lower the whole low octane table another 2-4 when...

Ideally we should have none. Right after flashing or years later. Since it is pretty much stock we need to assume the knock sensors are doing their job.

Around the switch to gen4 it seems that GM...

No cats. Thanks.

Will log them all next time I see the car.

Global or per cyl? I have looked at the total count. On a cam/exhaust car I find the misfires get pretty unreliable. Usually desensitize until it stops incrementing. (Assuming a car that runs right)

Swapped to a known good intake. Same split.
Swapped sided on the 02 extensions. Same split.

Turned off all fuel trims and started tuning with the wideband in the xpipe. Car runs and drives ok....

I turned dynamic airflow back on. (Still stock haven't tuned speed density side yet) It kept the same differential between sides just pushed both richer. To be expected because the cammed VE should...

Tried another set of low mile stock ls3 injectors. Same split. All injector orings looked good on both sets.

So I really think that leaves vacuum leak. The npp port is still sealed on the intake....

I tuned a cammed 5.3 truck last night that was kicking on traction control around that rpm and looked pretty similar in the logs...

Why is the map reading about half what it should?

Heads/Cam/Headers LS3 Vette.

Take a look at the log. At just about all lower air flow ranges the drivers side adds significantly more fuel than the pass side. Wideband was not connected on this...

Thanks again Ed.

Why do people expect a tune to correct mechanical issues?

Owner filled it to "almost full" with the tranny cold and car not running. Took over four quarts to finish filling...

Will double check. Thanks Ed.

A6 is still pretty new to me.

09 LS3 A6 Vette. 3500 stall.

WOT pull is right at the end of the log.

To me it looks like torque management kicks in, trans slips for half a second, then tq...
