No timing adjustment eh? Imagine that. Set it to spec or a little more if you like. Not because of altitude but because some people do it to squeeze out a little more power. I understand why but stock is fine too. After all the ESA system has been carefully designed to provide correct timing...

No need. I didn't say you were entirely wrong. All comes down to whether we're talking in general (you did mention that) or about this particular car. Besides, I'm sure they'll be input from others...

Not me. There was a time I'd have answered something like this quickly but after the tire pressure thread I'm holding off for the entertainment value. I pleased to see it's already getting up there ;)

Yes John...that's why I said it was an odd question ;) Grim: A scope is far and away the best tool. Note the word "tool" though. Like all tools you'll need learn how to use it and it's no substitute for knowledge. Because I'm fluent in electronics I use a general purpose DSO but you might want...

Actually no, that's a new listing from the UK I hadn't seen. It's the same tool though. A good deal considering what they went for new. As far as I know there were only two testers for OBD-1 Toyotas. One plugs into the diag port and offers the limited information that port supplies. Although...

I actually have two of those expensive factory TCCS tester/simulators and yes, they display injection duration directly in milliseconds. I rarely use them though. Scope is easier. If I'd known you wanted one I would have pointed you to Ebay a few weeks ago. One there went for $100 and the guy...

Hmmm. That's an odd question coming from someone possessing that kind of equipment and claiming to be an electronics tech..

With a downstream of the turbo induction leak it'll run rich because the air previously metered is not reaching the engine. The same leak, if it was large enough, would result in a lack of boost. Either way the AFM is metering too much air...that's why you're getting the code. Either that or...

No, they don't have the FPU system. Your problem could still be a loss of rest pressure although pressurizing the fuel system should have eliminated that possibility. I'd still take Nick's advice to be sure however...

You're still missing the point. Not only is that kind of gage not accurate at deep vacuum levels but even if it were there's no way the engine could make 29 inches of vacuum. Understand we're talking in a strict technical sense here. For uses such as determining engine health what you have will...

Thermal Arc AC/DC square wave with pulse, slope and adjustable freq here. Pulse allows the weld pool to cool during the background current. Good for thin metal and out of position (think vertical or overhead ) work...

Exactly. Although I don't expect everyone to understand the ocean we all live at the bottom of on a level guys like us do they at least ought to learn the basics. Dumbo: the simple explanation is you're using a gage of insufficient resolution...

Yet another victim of the death spiral in science education. It's not possible to obtain more than 30 in/hg on this planet and even if it were your engine couldn't do it...

^ You feeling ok? ;) As Poodles pointed out there should be 2-3 gallons left if everything is working right. Easy to figure out on a per car basis though: run until the light comes on then do a fill up and the math. Mine is 2.8 gallons but I usually fuel off of the the trip meter. Toyota uses a...

Advances it across the board. You might make a bit more power but nothing to write home about. As for fuel economy the first thing to check is codes. The second would be fuel pressure. Third would be to see if the engine is in fuel control (O2 sensor cross counting). I would be amazed if it...

I already know that stuff ;)

Stock timing is TeNDeGreeZ. It's set using a timing light on the crank pulley while turning the entire distributor. The engine must be hot and terminals E1 and T in the diag block must be jumpered when doing it. And if you're getting 9 mpg you have bigger problems than letting someone who...

Another guy who must be living on a different planet than the rest of us ;) Edit (for grim): comment deleted :)

I dunno about the car but here's a thought: maybe by doing less "stupid shit" with the N/A he might feel you're ready for the turbo sooner...
