A340E? I got to 300 at 13 psi without an upgraded intercooler and the stock automatic trans.

The oxegen sensor and A/F sensor do not put out anything that says what the A/F ratio is. It puts out a potential, that you need to interpret. That is what I am saying.

Have you noticed all the threads here with the opposite problem?

It is probably more accurate to call open loop the default on these older cars. If you are not in a steady cruise, steady non boost acceleration or idle when warm, you will be in open loop.

I was going to say the WB and stock sensor don't know what 14.7 even is. That is interpreted data. On the older sensor, like stock, you are going to see 450 mv (average), switching quickly when warm. Toyota WB's, they were calling A/F sensor when I was there, was 3.3v. And leaner increased...

He has everything that I have, and then some. I have nothing on hybrids, other than what I cribbed from him.

I am going after the book. I don't have anything to do right now. Babysitting.... In 852, which is is later and has the 1MZFE and other OBD2 in it has a spec. They say 0V at idle, and B+ when open. And that might not apply to the older TCCS. http://www.autoshop101.com/forms/h33.pdf...

Yeah, blue with white and white with black. And the plug on the switch is long and in a bundle. http://www.cygnusx1.net/Supra/Library/TEWD/MK3/manual.aspx?S=Main&P=144

The dual pressure switch and the high side switch are both above the wheel well, tucked down low in the compartment. Go by the EWD if you do it. But it seems like the wire was white and the other blue with a tracer. And the white might have had the black tracer. But go by the EWD.

I added a parallel ground to the A/C high side switch with a toggle. For very occasional track duty, and no other reason. All 3 of my electrics come on when I ground it through the toggle. It has to be before the swtich.

I read it in one of the older books, like 850 or something. But I am not going downstairs to read it.

http://www.autoshop101.com/forms/h24.pdf Page 23 and 24. And it wouldn't hurt to read all of it to be more familiar.

If your idle seems lean, adjust the screw in further. It is a bypass chamber where the air is not metered. Toyota stock tune is very rich in boost in lieu of forged pistons.

You don't run MAFT-Pro and the Lex meter. It is an either/or mod. A consensus doesn't make something so. There is nothing wrong with the mod, if the correctly sized injectors are used. Problems with the mod are with the install, or the car before the mod.

Want to make a wager? I even have a stock valve bodied, stock torque converter A340E equiped 91 turbo.

Here is 105/hr worth of free advice. You can watch for 51 then adjust to when it shuts off. That did in fact happen on the line at Toyota.

Good to see you did your homework. Those LQ4 LQ9 engines have the head that became the LS1 Z06 head. There is also the L92, but you would want more displacement with that head.

Not good. And my online supplier has raised prices significantly. I can't complain he had very low prices for years.

People look better with missing parts like fingers, just the same as cars do without their parts.

That may or may not be related to this. We can't fix it for you. Not for free anyway.
