Thread: Project LQ4 - V8 S10 - Sold.

The first few logs in full open loop always seem to be the leanest, wideband reading nearly 16's. It comes down pretty quick with a few 20min drives. So long as the VE tables isn't all over the place it should be alright.

The first time out was 16+ the whole time. That was a short drive. I made a quick trip around the subdivision and made an adjustment. Things were a lot closer the next time out. Low 15's for the most part. I could tell when I was in a new cell on the graph, as the wideband would show 16+ again. The last time out I was seeing a lot more in the high 14's and low 15's.

Well I burned just over a half tank on gas, but I think the VE table is pretty well dialed up to 4k rpm. According to the guide I'm using, the next step is to do some MAP/RPM WOT runs. Maybe I'll stick the go-pro to the back window for these runs.

So, I'm going to call the VE table done. Did a little more cruising around and a hand full of WOT runs to hit the higher RPM tables. Let me say... That truck does not disappoint. It feels quick! I moved on to the MAF table. It was actually pretty close right off the hop. Much closer than the VE table. I'd like to spent a little more time on it, but it's close. After all is said and done, I may tweak the VE/MAF tables a bit more using STFT's, but there's no reason for me to get them perfect. I anticipate an injector swap and a switch to E85 in the future. Then I get to start over...

Got a new sensor for the Wideband.



I'm not convinced there's anything wrong with the old one, but $45 seemed like a good investment. I have another AEM WB with a junk sensor. I can dial the truck in on a brand new sensor, and move my older used sensor to the other gauge.

My truck is on youtube!



This one's personal to me. Let's blow it up. Give it a like, comment and maybe subscribe.

she said your handling and brakes suck, get on it!

She seemed to. Surprised she didn't do a burnout.

It's a truck. Zero cares given for handling. The only time I care about turning is when I'm doing doughnuts!

That you were aware off.

Come on you made her nips hard with acceleration, you gotta make the puss wet now!

Sleepiest of sleepy trucks.

But anyway.. nice, really fckn nice. She aint to bad either

Believe it or not, she's local to me. Right here in Tucson. I shot her an email to see if she'd be interested in reviewing my truck. She said heck yeah. Super cool in person too.

Some footage that didn't make it into the review:

Was the wife watching through the window with a gun pointed to your head? Cute girls and boys are a no bueno here.

Nah. She was busy doing something with the kids. No matter though. Trusting wife, very professional cute girl and boy with self control. Just two gearheads doing burnouts.

Plus, she would have zero interest in this guy. lol

So, it turns out I've been going at the VE tune wrong this whole time. I wasn't completely disabling the LTFT's in my VE tune. There's a drop down in HPtuners that apparently doesn't work:



Once I raised the minimum coolant temperature to 284° the LTFT's were actually disabled. Lesson learned. Only cost me a couple tanks of gas. Derp.

After I got that figured out, I could to some legitimate data logging. First thing I did was hit the whole table with +8%. That put me pretty much smack in the middle of the error range the first time out.



Second drive:



Final outing for the night:



I may work on it a little bit more, but that was it for today.

MAF time!!!

That was today's project. Hit that table with +2% and did some driving. It's still like +4 / -6, but I only got to make 2, 20 minute drives before something else came up.

Also cleaned up some shift speed issues as well. Previously, if you stabbed the pedal at about 50mph, it would tag the limiter in 2nd before grabbing 3rd and fall flat on its face. Now, you can hear it just barely tickle the limiter before banging 3rd, and you don't even feel a drop in power. I'm going to raise the limiter about 100 rpm and that should completely alleviate that issue. FWIW, a WOT 2>3 shift in this light truck is fantastic!
