I think the 2006 GTO should be the same as my 07 vette. Look under System / Fans / Fan Desired %/ vs. ECT. Note that you can't change the temp scale and it starts at 192°. If you want better control...

I decided to work on tune a bit since I last looked at it when it was nearly 100*F outside. Since I decided to rework the VE I thought I'd upgrade to the 2Bar OS as well (so I can work with the VE...

I figured I'd come back and update this. I said earlier that I was getting knock that I couldn't seem to get rid of and that's true. However, as I kept dialing in both MAF and VE and then getting my...

I figured this would be a good time to ask considering how hot it has been in much of the US lately. The stock settings pull timing based on IAT and ECT pretty aggressively and I'm curious how people...

You could set your fans to come on earlier, but you're going to be limited by the fact that the low end of the table is 192*. (Unless you upgrade.)

No one has an opinion on this? It's really just the OEM 3.x row that confuses me. I've searched around but haven't really found much. Does everyone just fill this table with 1.0 and let the "ECT...

Can someone enlighten me on how the "ECT Spark Advance Correction - Mult" table works? I understand that it is a multiplier based on ECT and RPM, but the table isn't making sense to me.

The...

Oh, I did think of another question. Does the Commanded EQ Ratio (SAE) PID have the same resolution as AFR Commanded Hi Res? At least on my E38 OS I don't see the low res version so I'm thinking it...

Ha ha! Okay, thanks for the info. Since I actually wanted lambda this will work out fine.

Hmmm... no comments about this? I found some other posts that seem to indicate that "some" PCMs will show EQ and others will show lambda. I prefer to see everything in lambda values and if Commanded...

Me too. :o

I have a somewhat modified 07 Z06 and I get consistent knock that doesn't go away despite pulling timing and adding fuel. I'm still trying to eliminate any mechanical cause but it does...

Is there a known issue with the Commanded EQ Ratio (SAE) PID? I ask because I have been using a custom PID for commanded lambda that was AFR/14.67xx but I saw that I could log EQ ratio and thought...

I've used the Innovate LC-1 before and it seemed to work fine, but I currently have the NGK AFX. The reviews that I read seem to indicate that the AFX is more accurate, but it's hard to tell the...

I'm not an expert by any means, but why would you not want to tune VE? Are you saying that running MAF only is preferable? I could see someone at hptuners suggesting a custom OS with a real VE table...

C6Z_sd, I'd be interested to see what you come up with as I have a very similar setup ('07 Z06, torquer, KB II). I've left mine hybrid but I still want to tune the upper RPM VE formulas. I've made...

For what it's worth, I've definitely noticed the difference when I'm tuning VE (or MAF) and have DFCO disabled. The pops from the exhaust go away entirely. I'd be interested in how you manage to...

Okay, I think I have an issue with false knock. Here's the details: The car was tuned elsewhere and I noticed that the tuner rather aggressively turned down the various knock parameters. (Probably...

Thanks IDRIVEAG8GT, that was the hint I needed. I put the RAF (Airflow Final Min) back to stock and the surge went away almost entirely. :yay:

I also think I learned something -- I had thought...

Okay, but I've tuned VE in the low end to where I'm spot on, and even when I'm running with the MAF disabled it still surges like that. Heck it might even be worse. I know I'm a noob at tuning but if...

I have a problem with the throttle hanging or even surging at low RPM. It is most noticeable when stuck in traffic and I get going only to stop again. The car will surge up to 2000+ RPM for a few...

I found a place locally that sells ethanol-free gasoline and I'm currently using that to tune my (virtual) VE and MAF tables. My question is, after tuning is finished if I run ethanol blened gas...

I was just about to post that I looked at the IVT Gain and figured that was why the commanded lambda was changing. I did max out both the closed loop enable ECT VS Startup ECT table and the O2...

I am having some strange results when VE tuning an '07 Z06. I have already done some VE tuning using the STFT method but now I am trying to finish it up using a wideband.

The first thing I noticed...

Okay, I have a dumb question. Does changing the value of stoich in the 0% column do anything on a non-flex fuel vehicle (an '07 Z06 in this case)? I only ask because we get the typical "up to 10%"...

Thanks, that's what I was doing (filtering out data when fuel trim cells were above 15). However, isn't that when EVAP is open? My understanding is that 16-19 are idle and 20 is decel. I don't really...
