Great stuff figgie. ECU idle deadband is 20 rpm so if you hang LEDS on a few of those outputs you'll see how active that little bugger is. Toyo might be referring to 125 steps either direction from the middle but I could be wrong so I'll defer to your research. At any rate, you're my kinda guy ;)

Wow, some serious misinformation in this thread although figgie knows of what he speaks...

I know a guy in that area who specializes in 7MGTE problems, especially drivability, EFI, and emissions problems. Doesnt come cheap though.

Say what??

Good post...the sudden display of logic and common sense was shocking :icon_razz

It boggles the mind.....

Hello from a galaxy far away.... I'll come out of hiding long enough to add my compliments to SH as I know wrenching is not his forte. This kind of work with a successful outcome deserves accolades, not only for the skill involved (all things considered) but for the cohones to try it in the...

Hello from JFK airport.... Look on the left fender under the master cylinder. See that little gadget the brake lines go into? It's called a proportioning valve.

lol @ Joel..... I was an engineer for much of my life before changing careers. My education is as an EE but I've work in other disciplines ie; mechancial and industrial. My current occupation is also a technical one so I guess I'm still an engineer at heart. Engineering is a good profession...

I simply tell them I'm in the Jehovah Witness Protection Program and hang up ;)

Well, the title certainly makes no sense as it relates to the question. Might want to cut this guy some initial slack though because based on where he's from English may not be his native tongue.

DARPA huh? No kidding. Lol, I'd ask but I know if you told me you'd have to kill me ;)

I have a Fluke DSO ScopeMeter, a model 97. Don't use it too much these days as I prefer the automotive laptop based scopes made by PicoTech. All my DMMs and other electronic test gear is Fluke though. They do make nice stuff.

The stock coolant temp issue must be the sensor because the gage movement itself is very responsive and can be made even more so. Plenty fast as it comes though. It has to be the thermistor in the sensor or the thermal mass of the sensor itself. I wonder if a better one is out there.

I have no dog in this fight but I'm still of the opinion anyone who thinks skin effect applies to secondary ignition is barking up the wrong tree. 3p: what are you, design or process engineering? You sound like a design type.

Just so you know turning the key on will not run the pump and pressurize the fuel system. The pump only runs when the key is turned to start. It does runs at high speed until the engine starts. That is unless it's been hacked to run at high speed all the time, a common and (mostly) uneeded mod...

The 7MGTE uses a distributorless ignition system often called DIS but more correctly called DLI. The plugs are fired together in pairs, once on the compression stroke and again on the exhaust stroke. The firings on the compression stroke are called true firings, while the ones on the exhaust...

Look under Misc Vendors Jake....

Well, skin effect is an attribute of high frequency AC current, usually associated with RF. Not accurate as it applies to spark ignition. Here's one for you. The plug pairs in a DLI system like the turbo Supra are in series right? Did you know if you put each plug from a pair in two different...

Yes! F104 is correct. It's all coming back to me now. The darn thing has been on my 87 for many years but I once had to drive around with an 18 mm spark plug as a drain plug so I know it fits ;)
