As was said it's normal. Any time the engine is in transition it won't be in closed loop. As for the rest you guys crack me up. What do you think was used before the WB (which is recent, or at least recently affordable) came along? People have been tuning with NB for over 25 years. As long as...

"Ion Crystal"?....lol, that's great. As dumb as I think this mod is, two words: selective yellow.

Read them all....

Orange crud?

The lack of rest pressure shouldn't cause drivability symptoms unless the cold start injector is at fault or one of mains is stuck open and in that case the a/f should be rich. You appear to have a flow problem. Sounds like the pump relief valve might be opening. That'd explain both issues but...

That's a lot of work for a guess Weez. Does the return line deliver a minimum of 1 liter into an open container in 30 seconds? Does it do the same at the inlet to the rail? What does fuel pressure do with the regulator vac hose off during a snap throttle test? How much does it drop? Got a meter...

I wouldn't call it insanely good...it's easier than tigging thin stuff. Preheating might be a bear though. Aaron: Can you still do these with NF on the head side like we talked about before? Can you get 'em in CRES?

Lol. Now that's a switch. Weren't you one of those reporting increased EGT? He's calling you out ;) And yeah, even though we're all guilty of it ad hominem does get old...

Lol. Good one ;) Dr Evil: I wasn't referring to the service manual. I was referring to internal Toyota engineering and service training information. You know, stuff from the engineers who designed the car and programmed the computer, written for professional technicians who understand how cars...

Bravo Doc. Someone finally brings up coolant bypasses. I was wondering how long it'd take. I don't often run into people who know most engines have one somewhere.

Moved from a thread in the N/A section: For proper testing of the charging system you need to get an ammeter involved but for voltage testing the battery should be fully charged and alternator output current below 10 amps. At idle voltage across the battery should be between 13.5 to 15.1. For...

Cuel has it right for voltage testing though it's tough to test an alternator completely without getting an ammeter involved. For voltage testing the battery should be fully charged and alternator output current below 10 amps. For current testing run the engine at 2500 rpm with loads applied. If...

Appears you know something too. Yeah, my comment was directed at overcharge. It's the only reason it'd gas. A valve regulated recombinant gas battery will just open it's pressure vents and do the same so you'll gain nothing there. A check of the charging system would seem to be in order. Low...

Sure...as soon as you explain why you'd be storing batteries on a block. That has to be one of the oldest automotive myths around ;)

Clip: They work if the stuff isn't too heavy. Messy though. It'll suck a lot of CFM too. Fletch: Try some more aggressive media. Aluminum oxide for example. Get some at Harbor Fright, et al. Garnet is the next step. Silicon carbide is even more aggressive but it'll eat your cabinet alive if you...

Oops, missed this until now. That is nice work. From what I've seen on how you did this there shouldn't be any problems with it at all. In theory it's electrically sound and compatible with the stock TCCS. Looks good too. Nice job.

Copper work-hardens Nick, as do many materials. Heating and cooling it slowly anneals it ie; makes it soft and able to take a compression set again. It's an old trick.

Not that I'm an advocate of it but people have been re-annealing copper washers in aviation for decades. They're what seal spark plugs on piston airplanes. A whole lot more pressure than fuel and it works fine. I also have a Bosch K Jet equipped engine that uses the things all over the place and...

Ah yes, Autoshop 101. Because I have even better info I keep forgetting about it. What's really unbelievable is that resource has been repeatably mentioned here yet people refuse to read it. If they only would I could move on. That ought to be motivation enough for many ;)

Nothing runs like a Deere ;)
