I just wanted to update this and say that I FINALLY resolved this issue after a day and a half of modifying my tune, flashing, rinse, and repeat. Taz and itspeat, the issue lies within the virtual...

I just wanted to update this and say that I found the issue. The air fuel ratio sensor itself had a pin that let go on it's detents and was barely making contact with the communications circuit of...

Hmm.. I may just have to give replacing the wideband a shot then as if I remember right, I ran the ground cable right on one of the main grounding locations by the driver's kick panel. When I do...

I obtained my 2018 tune file from the repository, if you ever wonder if a tune is available there, check that out first. That being said, I was in the same boat when I bought my 2017 and had to...

Mufflers don't help your situation at all. Rumble mode is only meant to affect initial starting and DFCO is the area you want to look into. The minimum spark tables as well. I may be leaving...

Original post modified. Thanks in advance guys.

While I'm testing and trying out different WOT air fuel ratios, any time I run my lambda down around .80 the log shows me that after 4100 RPM a MASSIVE spike in lean activity running all the way up...

Okay so here's some feedback after making some changes:

I initially ran an SOI of 330 as per your suggestion, that netted no positive changes and if I recall correctly I actually got hurt by that...

That belt is like 3" longer than the one I run and we have the same setup, but obviously I'm Camaro, you're Vette. I run an 85.4" if I remember correctly. What size was your original belt, or should...

Yeah, the EOI split base tables. You are right though in the fact that the PW is a bit high considering what's been done to it. I don't disagree at all. Is there another EOI table I should be looking...

Managed to get it nailed down last night and took it out for a spin today. I'm seeing different SOI peak nominal numbers down in the high 330's but INJ PW's have not changed around WOT. Total duty...

Am I smoothing or interpolating? Full selection or between vertical or horizontal bounds? Also you are recommending I touch just SOI base and not another one of the selections correct?

I am...

I raised the desired rail pressure to 3050 psi and I'll see how it reacts to that. I have to drive the car today anyway so I should be able to get a decent log.

Where exactly should I pull 20 out...

Did you get a chance to look at the log? I am more on the novice side of tuning and am not too informed on what SOI and EOI necessarily does. I am aware of it's function, but have a limited...

I'm actually a bit surprised I didn't lose any boost actually considering the durations are a bit longer than previously. Normally, from what i have found, increased airflow causes a drop in boost. I...

I inquired about this setup some time ago in order to stay relatively compliant and trouble free within my state. I would had liked to go with a legit custom grind or a PD cam of some sort, but my...

Unfortunately, my hands are tied from a legal standpoint, with that being said, I'm not looking for an all out racecar either so it's not a big thing to me to chase wild numbers, and I'm definitely...

No it makes sense. When I bought the car I actually had a 12%er already installed on it and I had to step it down but the smallest pulley available for it was this 5%er from ATI. As of right now the...

Oh yeah, I forgot to mention. I'm running a 5% lower pulley and making 11 psi currently.

Trouble is I live in that gold state that makes it very difficult to even mod to make the car more reliable. I checked around. ALOT. What I found is that my cam choices were extremely limited when it...

I'm going to be doing a Katech oil pump swap in my 2017 A10 Camaro ZL1 soon. While I'm in there I'm going to do myself the favor of swapping over everything to the more reliable non DOD/ AFM delete...

I got in touch with Mike @ Soler and I think even he is agreeing that the TB is looking highly suspect due to the log I posted where it started up. He thinks it may be binding in colder temperatures...

No I have not. I don't even know how to do that quite truthfully. This issue started seemingly out of nowhere one day from what I remember but have barely gotten around to addressing it as of now.

Are you talking about what's in my tune? I have not touched the transmission stuff as my T87A has not been unlocked and I have not touched anything regarding transmission stuff while tuning and...

This isn't the first time I've heard of tuning issues or just general issues with the ported TB's. These LT's are super computerized and have way too many parameters available to tune so it can...
