Any updates on this? Just curios I have a C6 Z06.

So yeah, this fixed my issue and I'm really happy about it :)

Thanks, moving on! :)

I'm guessing the problem is P0128, which is worried about the Coolant Thermostat. I think there is a logic process where by if Engine Coolant doesn't get to 165 + or so then the computer assumes the...

My stock Z06 file said 26.16 and 770.88

What does a stock Z06 file say under the Speedo area in HP Tuners?

Question for the dudes out there with OEM ZR1 tires or a ZR1 and HPtuners.

Recently I installed ZR1 rims on my Z06 and I thought I should change the tire size to the 26.6" size.

What tire...

Yeah, it's modded so probably not bringing it to GM so they can tell me to screw off :)

Could be the sensor, I'm popping a new one in Saturday when I do the headers. We'll see.

no dice?

Today on my ritualistic Saturday morning cruise in my Z06 my A/C turned OFF. At first I thought maybe I had hit a button, then I could see the PCM LCD telling me Engine HOT, AC Turned Off (or...

Bill,

So my stock OS table for my single PWM fan will start at 196 and you think there it should be 0% then jump to 90% at 201 ? If I put something in 196 above 50% does that mean the fan will...

I'd like to know the same thing. If somebody has an LS7 stock OS table they could share that works great (which I think was in this thread already) I'd really appreciate it!

When I GIVE the engine throttle and the RPM's are climbing upwards it would pop/crack/hesitate like it was super learn but wideband showed it wasn't. Like I said above, I turned OFF the throttle...

Say, between 2600 and 3100 RPM moving about 65 g/sec air into the cylinder ....

I want to amend the above information. The hesitation is all gone only thing left is some popping out the exhaust. My exhaust system may be the cause of that because I have TSP TD system with custom...

How can it be un "screwy" ?? just smoother? It's pretty close to on the mark as of now except a few spots.... I've had about 8 hours total of tune time.....please take a look at the latest file. I...

I changed the throttle cracker settings and things got much better. Then I tried another timing map and the results were great. Now the car is pretty good and nearly perfect. I need to mess a bit now...

Strangest thing. I turned OFF the Throttle Cracker and re-built the timing map (put in a lot MORE timing) and the problem is almost fully gone. Any ideas on that guys?

Weird because 2 weeks ago it...

Thanks for taking a look. No, nothing wrong the TPS actually. Good observation though. In that frame I'm coming off the throttle to get the car to start the popping again. At least SOMEBODY took a...

Anybody want to take a look? too hard? :)

There are my logs. Notice the short but frequent lean spot before the AEM A/F goes back to stoic. How do you adjust that sort of situation.

It's an OPEN LOOP SD Tune, sorry didn't say that.

Guys I'd like some input from the experienced guys out there that may have seen the problem I am having.

My car is a H/C car and the dyno numbers and all that jazz are great. What is not great is...

Trial and error, reading, looking at other people's tunes and more reading. Anybody can look at my tunes at my site....

They are in...

Ok, understood. However, cam advance and timing advance seem related but not the same. Again not sure if the +6 had an effect on my need to go lower then stock in some areas of my tune.

So, 6 degrees of timing advance?
