Not that we should trust that.

Need to avoid main relay contact/coil confusion. The ECU powers the main relay while the main relay powers other things. As Dirgle pointed out one does not want to connect anything to the M-Rel output on the ECU. Connect to the main relay contact (B+ circuit) instead although I'm not a fan of...

That was a good call. From playing with the box on my simulator over the years all it cares about is B+. IGSW is for M-Rel control only. In fact I've used the shunting trick myself a few times. It's a quick way to verify Vc isn't pulled to ground because if it is the box will be paralyzed.

Same here. The books also so state but I suppose anything is possible.

The answer to your biggest question is no and the knock problem is already moot.

My pleasure...

All that points to either a maladjusted TPS or an induction leak. My bet is on the latter.

A lack of power on B+ and no MIL jives with the main relay being off. What Dirgle is getting at is without power to the ECU's IGSW (IGnition SWitch) input (how the box knows the key has been turned on) the ECU won't energize the main relay.

I like when my hose builds pleasure...

It's not the heat that's bad, it's the stupidity :)

It's America's center of weird. Weirder than even California....

Trust me, I'd forget it all in a heartbeat to trade places with you. Then I'd be set for life :)

You bet. The 7M TCCS is an outgrowth of the Bosch L-Jetronic system. Toyota calls it L Type EFI. L is for "luft", the German word for air. Means the system measures airflow rather than manifold pressure and for things to work right all of it must be accounted for.

Good grief...

It's finally over. Thank God :)

Pirate air is bad m'kay. EFI 101. So is too much free time...

CDS is the condenser fans. RTR are the headlight retract motors. Integration Relay 2 not only operates the motors but also the headlights. The tail light relay operates the tail lights. Duh. The Circuit Opening Relay operates the fuel pump. All this is evident from looking at the TEWD...

Four years old but still good for a chuckle :)

Well, don't go east. Oakland is not a place you want to be. South of SFO will be safe if not pretty. Burlingame, San Mateo, San Carlos, etc. North of the bridge is OK too but not cheap. Bring jackets because Mark Twain (who really didn't say it) wasn't kidding. And be sure to take the family to...

I r corn-fuzed. Anybody who has enough skill to do the first shouldn't need to ask about the second...
