I am curious what kinda power can be made with stock truck. I have the hardware leftover from my C7 Z06 and would like to try it. Anyone?
Thx

Thanks for the great content and suggestions! It's for a road course car, so conservative (cool) is key. Highflow cats are in the ARH headers, but may swap out for catless if the heat becomes a...

Doh. Bummer.:(

I do not have HPT Pro due to logging Wideband over 0333 unit.
Anyone know if DashLogic unit's analog input are seen by HP when plugged-in?

I own an EGT probe from a previous vehicle project and never installed it. (goes to Zeitronix ZT2 box which can output serial data, but the sensor signals are in millivolts levels (.001V).

What is...

Whoa! :worship: Thanks for all of the responses! (more than I bargained for!)
Thanks to all! I'll have some data-logs to share soon....and likely ask for more help. :)

For those experienced in GEN5 Z06 tuning, what AFR seems to be the sweet spot? 11.5?
Also, I'm going to plumb-in an EGT probe right at the collector on headers so I'll be able to see the correlation...

HPTuner should make you pass a quiz on this prior to the software being able to flash!
Anyone who's even CONSIDERING messing with their Gen5 should read and understand this! Thanks Higgs!

Was just through Buffalo on the way to Niagara.... (can you tune a Cat 3126!) ;)
I'm willing to make the trek for a worthy tune. I want someone to put my on the right course. Will you be at Carlisle...

Any recommendation for good Gen 5 tuners in PA/MD/NJ/NY area?

Awesome. Yes, have hi flow cats with sensors right behind (American Racing headers).
Also, they come with wide-band bung so I can drop that in and monitor my AF ratio.

Also, any baseline idea of how close stock will be with long-tube headers (with cats). and cold-air intake only?
I've been told that exhaust mods (i.e. Headers) will cause codes. Can this be turned...

Awesome. Thanks! A question regarding flash/OE Warranty, etc.
If OEM warranty is a concern, and a tune voids said warranty, is there a flag set in the ECM making this apparent? Is there any way for...

Apologies for a bonehead question, but it appears to me that the 0333 goes into the OBDII port. Since it's occupying that, how does the HPT then plug in? Thanks for clarification on this.

That reminds me: on the C7 Z06, where are folks installing meth nozzles? I haven't really looked closely at the options as of yet.

All hail meth for cooling.:worship:
On my previous car, (heavily mod'd V8 AMG mercedes) I chased the fire with ALL sorts of additional cooling (bigger heat exchanger, bigger pump, HUGE trunk tank...

It looks like $1395 is the lowest package needed to do programming. I'm I assuming correctly? Any recommendation for a J2534?
Thx

On a related note: on C7 Z, where's a good spot to get the wideband wiring into the cockpit? I haven't studied this yet.
Anyone using Zeitronix 5V into the HPTuner interface? Is Pro needed for this?

What does it take to update the GM calibrations, other than going to Stealership and getting raked over the coals, etc.?
Thx

I'm mostly interested in fuel and spark right now. (tuning for a few mods added).
Thx

Gotcha. Yes, it pulls up quite a lot, but I figured someone may have a file that has all of the stuff already configured.
I was surprise that it wasn't logging injector data straight away...I was...

Looking for base config files to get me going.
Couldn't locate any previously uploaded files.
Thx!

Gotcha. Wasn't sure how much would need to be done to get it back to where it needs to be. What kinda AF target for these beasts? My prior blown beasts, I aimed for 11.5:1.
Thx

Looking to get a base-line tune for my '15 Z with Halltech CAI and America Racing headers (with cats).
Can tune further with wideband, but was hoping to get close with a provided tune.

New to the...
