Brian Wolfe hit the nail on the head in one of his interviews. He said the oems/govt went all-in on electric too soon. The only practical solution currently is plug-in hybrids. They check all the boxes but were more-or-less skipped over in the premature rush to electric. Since most of your...

Yep, just fan settings if you want to take full advantage of a tstat.

From the wording it looked like you were running e85+meth, which would be totally unnecessary to achieve peak performance so I was wondering. Awesome GTO! IMO that and the GXP were some of the best all around performance cars ever made!

@Mach1Racer youre running e85 + meth?

I don’t think it would be a big difference there. The pump runs 65-80 psi all the time so making that 75-80 or just 80 is within the design envelope. It’s just a bandaid fix, if I’m right.

Been contemplating this. If my interpretation is correct, that debris plugging the jet pump .017” nozzle is causing the issue, then how could controls fix it? Well, it’s pretty chintzy, but if they commanded higher fuel pressure all the time it would make a compromised venturi jet work better...

On the 6.2, Brian Wolfe was in the middle of the decision to kill it. He explained it in surprising detail in his interview with PBD. Basically the 6.2 had fallen behind the competition in output so they were slated to update it but they decided to replace it instead. Cost was a factor but I...

It’s not so much about finding a tuner as it’s impossible to make it work correctly with the ford logic. Two issues come to mind. 1. Your maf transfer function has to either assume the meth is on or off. And whichever you assume it will have corrective fuel trims when it’s switched the other...

Tuning for it is basically impossible to do correctly. If you’re stuck with 93 and want more power, consider an interchiller.

I just opened the 3rd one and it did the same thing. After the cams were commanded off of 0, they went to exactly 0.00 at 0% duty cycle. It's strange but could be normal. It's also odd that it never shows a fault for the cam. If you drive around at loads and speeds that never command over 0...

There is some information that was published here RCLRPT-25V455-7716.pdf that says "Teardown analysis indicated that jet pump orifices on some returned parts were blocked by contamination." That's where my conclusion came from, because the venturi in the jet pump is only .017" in diameter it...

I took a look and noticed something a little odd but no smoking gun. Before the exhaust cam ever moved (0% duty cycle) the actual angle varied +/-.5 deg until it was finally commanded off of 0 at timestamp 40591. From that point on, 0% duty resulted in exactly 0 deg angle. That is suspicious...

I think they’re too big to fit with LT headers. I did a write up on this a while back but on the PS you can bolt the stock gt500 cat to the stock header collector with a spacer and it fits surprisingly well. On the DS, I added a flange to the stock header that the stock gt500 cat bolts to. The...

I don’t think it matters which hole the spring goes in.

When I saw PAC springs that was my first thought, but that's not what the codes are indicating. It's not a desired vs actual mismatch. Mismatch or deviation are codes P0011, 12, 14, 15, 21, 22, 24, and 25. As I explained, your codes (specifically 0390 and 0394) are saying there's a problem...

Yes, the things I mentioned earlier: cam position, desired position, and phaser duty cycle, but they need to be on a very fast data rate. There's no guarantee since it appears as though the errors it's looking for are instantaneous and it adds to the sum each time there's a problem, and when...

I thought about this a minute and this is actually an error of the cam position sensor, not the phaser. It’s saying the cam positions sensor isn’t getting valid data, either rpm or position out of range or no or intermittent signal.

The PS is just a pickup. I suppose it's possible the pickup is plugged, but unlikely in my opinion. There are no small orifices in the PS. Both sides are spring loaded to ensure the pickups are as close to the bottom of the tank as possible. It spring-loaded with some travel to accounts for...

To differentiate, there is a phaser and a phaser solenoid. It's fairly unlikely that the phaser itself could cause these particular error codes unless the cam jumped a tooth (out of range code). This doesn't appear to be a "it's not following commanded" type of code. The good news is that it...

Ford uses some methodology called FMEM. Basically, they try to think through all the possible failure scenarios and build fail-safe functionality into the logic. When it senses a cam position problem, FMEM sends all cams to "home" or "park" position, which is 0, 0. That's why they do what...
