Hi folks. I just got the HPtuner software on Monday. Tried setting it up on my laptop that night but I had problems with the drivers getting loaded. I think I sorted it out. Will record some runs tomorrow. I cant wait to get this fixed. The frikin car just pings all the time. Sucks big time.

ls1_lover

Ok, so i got this software configured. It looks like I have the drivers loaded. I am going to write the file that is on my car now to this computer.. and then post it up here.

I started looking at the HPtuner software... Looks like I bit off more than I can chew with this. So many options, so confusing.. I will be back in the morning with my car's file.

Thanks. !

David, hang in there brother. I am sure you will get a handle on that software. There is a learning curve with anything, it takes time. Maybe a little longer at our age…lol

Once you figure this one out, there is only one way and thats up!!!

Thanks AL. Have you ever seen a pic of the dashboard for the space shuttle? There must be 1000 *****, 10000 gauges, 1000 switches. Thats what this software looks like.. sort of. I am sure that I can learn what to do with time. It is just that I just want it NOW. I have been driving my car for about 6 months now with that frikin ping going on. The few times when it would not ping it was fast as heck. However, now with the pinging I have to drive like a grandma.

This is the reason why I miss locking out advance on the HEI , dialing in 12-14 degrees of timing using a vacuum gauge at the throttle plate of the carb. Jet the Holley DP square at 78 with one turn out on idle screws and it was pretty much dead on.

Post a copy of your tune file please...

I have a small suggestion: Don't drive this car WOT if it is knocking bad.

jaydubb

If you just post a copy of your tune file, one of MIGHT be able to point you in a direction to resolve the issue...

Tune file attached.

I was finally able to read my cars file. I have a day job as a Database administrator so I dont have a lot of free time during the week. I drive to work 26 miles and then home.. so that is 2 hours in the SS living with this Friking ping. So I had trouble at first loading the HPTuners drivers as Windows 10 was crapping out. I finally sorted that out and then HPTUN would not read my file due to some more obscure settings.. Now it is all sorted out. The file is up here. I anxiously wait your comments. Thank you very much for your help and support!!!

I looked at your tune. Has this car been modded at all?

Only performance mod is the cat-back

ls1_lover

Hi Jay, mods,, slp loudmouth 1 cat backs. MSD coils. Thats it. Nothing else. Oh, I had did the LS6 valley cover swap.. I know this affected vacuum because I can see a diff in the oil pressure gauge but the LS1 was pinging before that.

I was looking at SD tunes?? This way I can get rid of MAF, O2s and IAT sensors.

jaydubb

Have you had this car tuned before? The tune looks very close to stock. Can you log it and post the log?

jaydubb

No need to go to an SD tune on a car with only a catback...

jaydubb

OK...

This tune is a MESS! Stock MAF table and VE table. Stock PE table. The only thing changed in YOUR tune is

- 2 degrees of timing added to the ENTIRE Hi Octane spark table
- WOT shift enable/disable RPM
- Some torque management stuff
- Shift pressure
- Fan turn on/off temps

How much did you pay to get your car tuned? I wouldnt even consider an aftermarket ECM.

Seeingh stuff like this makes me HAPPY I bought HP Tuners. You will be glad also, once you learn the ins and outs of HPT. Did you get the Pro version? I hope you did.

This tune needs work in the MAF table, PE table, VE table, Spark table... I hope you have a wideband.

Wow...

If you want to verify what Im saying, go to the tune repository, download a stock tune for your year and look at the comparison log. See for yourself...

jaydubb

Even with SD, you will still need the IAT. You will also need the O2s if you ever want to run closed loop.

I wouldnt do SD unless you cam it or go with forced induction. If youre concerned about the MAF being a restriction, get an aftermarket MAF.

ls1_lover

It was tuned by the other owner... and I did it again about 2 months ago. I paid 300 bucks. Its a mess I know by the way the car drives. I did not buy the Pro Version. I think you mean the version that lets you use the wide band 02 in the exhaust? I did not purchase that. So where do I start? It is even idles like crap now too. What is the quickest way to get this fixed. I am tired of throwing money at it. At this point I have about 14k invested in this car. 10 to buy it.. another 4 in service, maint, now tune software. Can I just get a tune that I know will not blow up my engine.. flash my cars ECU with it and then go from there?

So the only changes... 2 degrees of timing, fan settings, and abuse mode changes. Also, the line pressure changes on the trans aren't really needed (or recommended).

That's certainly not worth $300.

And the VE and MAF are stock.

It shouldn't be driving like ****. Barely anything changed. You have some other issues.
