LMK how this setup works out, I would like to use my rebuilt 95 bottom end on my vvt head. Any plans with autox for the car?

After driving it to work today, I went to go start it up this evening, and got NOTHING. Crank, crank, crank. I ran high speed logger, and I get no data in my file. Seems like a dead cam or crank sensor from what little I know about the high speed logger. I think I grabbed a spare of each sensor when I bought parts for my build, so with a little luck, this will just be a hiccup...

Yup. Dead cam sensor. Swapped it out & it fired right up. Damn, that would have really messed me up if it was already dead when I was trying to get first start...

How is the oil pressure when vvt engages?

I'm still tuning ve. When I get closer to happy, I'll add in VVT.

Car just utterly assploded. Sounded like a chirp from the wastegate at 3k. Then dead. The guy behind me said I shot a fireball, then something like a cigarette came out the tailpipe.

I didn't install a cat on your setup did I? I can't think of anything else besides the.insides of a cat that would come out the exhaust.

Turbine shaft shaped item, perhaps?

No there IS a cat in this setup

I heard nothing metallic when it happened. Just a chirp like the bov giving a puff, which it shouldn't have because I was at maybe 3500 rpm at a low map pressure. My wastegate is disconnected and wired open. Afrs were reasonable when it happened. Then the engine just lost all power. It didn't die, but it ran more​ & more rich and made zero power. I turned the ignition off. And now it won't start. I'm waiting for a tow.

I guess it could be the cat core? That would block the exhaust if part of the core was jammed in the exhaust. I'll try pulling the mid pipe when I get home.

I walked up the sketch stretch of road where it died, and look what I found!

Well that sort of looks like the insides of the cat. First customer to have an issue with it. They are magnaflow hi-flow cats, so I was not expecting them to have problems. I would drop the mid-pipe, then take a look with a flash light inside.

​​​​​​​I am not sure why blowing out a cat would cause the car to not start afterwards though.

It's not starting cuz the rest of it is sideways in the pipe

Did you ever see the original Beverly Hills Cop movie?

OK, so what I thought might be a blowed up motor this morning turned out to be just a blowed up cat. This is definitely a case of shitty n00b tuning skills. I drove the car to work yesterday for the first time and did some VE auto tune. I kept fighting & fighting my AFR's. I could never really get it to play nice. I was running lean everywhere- like VE of 100 in cruising to get to target AFR. So, I cheated! I bumped the req_fuel value up by an additional 50% from 4.9 to 7.4. This helped, but something was still jacked up.
Then last night, I discovered that I had the MAP calibration wrong. The MS3Pro has an internal 4 bar MAP sensor. I wasn't calibrated for a 4 bar, and was reading 69 kpa in 101 kpa weather. I realized I've got in the habit of just looking at the boost gauge to eyeball MAP, and covering up the TS MAP gauge when real estate is short. So, I recalibrated the MAP last night, and started driving in to work this morning without setting the req_fuel back to 4.9 where it belongs. It was running mad crazy rich (10-12 AFR), and I was VE tuning to pull fuel out. I was in morning traffic going about 3500 RPM in 3rd when I heard what sounded like a BOV valve fart. Then power just took a dive, AFR's got super rich, and I had to turn off the motor.
The guy behind me was a standup guy. He blocked traffic with his car & helped me push it ~100 ft to a safe spot. He was all wide eyed & said: "Dude, that was nuts! You shot a fireball, then something shot out of your tailpipe!" I asked him what it looked like, and he said: "Uh, like a cigarette, but big and round on the end." Of course, my mind went immediately to horrible places (turbo, engine internals). But I had Lars put a cat on the exhaust, so the cat is pretty much the only thing that could escape the tailpipe.
Next lesson: Never assume your car is healthy enough to remove all tow hooks. I removed all baby teeth years ago, and didn't put any back on after this build. I had to walk home 2 miles to get baby teeth so the tow guy could hook up to the car.

Also, a metal core cat is really damn hard to get out even after it's been burnt to shit. I guess I'll just run fakey cat unless the stank drives me nuts.

You had a shitty tow truck driver. Baby teeth are not required to tie it down on a flat bed, nor on the dolly types of tow trucks.

No, he was good. I got the baby teeth before he showed up. We tied it down via the tires, but we used the baby teeth to attach the winch & pull it up on the bed. With the front lip being so low, I don't think he could have grabbed anything to winch without tearing up the lip.

All right! With MAP settings correct, req_fuel where it's supposed to be, this thing tunes right up! Funny how that works...

I wasn't logging, but it looks like VE auto tuned a couple cells in the row above 100kpa. Luckily, it's pulling a little fuel. I'll have to run a log to see how much boost I'm generating with the wastegate wired open.

I found that it was somewhere in the neighbor hood of 4-5 psi with the wg wired open when I had my IWG set up still on the car

After a nice road tuning session yesterday evening, The car wouldn't start this morning. I tried checking the composite log, but couldn't get anything. So today I bought a new cam sensor. I'm getting cam and crank signal just fine. Maybe I just didn't crank long enough this morning.

I still can't get it to start. I tried reverting to a previous log, and that didn't help. I can hear the fuel pump prime, and the exhaust smells gassy. I've attached a log & tune of my crank attempt. Can anyone spot what's going wrong?
