I really like my GReddy Profec B Spec 2. It is an easy install, and easy to control. As long as you understand it.

Welcome to Supramania. :)

34 is your problem as described in the title. But you have to fix all the problems. 51 would tell the computer you are not at idle. Ignore it for now. 24 is the intake air temp circuit. That is secondary correction, and won't cause your problem. Come back to it, but fix it after your intake leak...

It seems like there is a thread with parts needed for MKIV rear swap on MKIIITech.

IGt is the signal to turn on the coil. It is an on/off signal. IGt is ignition trigger, or ignition timing, depending on which Toyota book you are looking at.

As though that is some sort of qualifier. The 7M record (because breaking it isn't important) is over 700rwhp. Stock means original parallel turbo system, exhaust, and boost control set to 12 psi, or whereever it is.

But you have to put in the passenger seat. Or something else. Cutting weight is a great solution, this is true. If you can drop 400 lbs without hurting the car in some way, do it. It would make for better all around performance including breaking and turning. One other thing, I would get better...

With all the Supras I have owned, I wonder why I never have all of these "common problems"....(rhetorical)

See the O.P. The A340E has a taller overdrive than the R154 or W58. And the 3.73 is lower (taller) than the 3.91 in yours. Assuming you have a 3.91 based on your avatar of the old grill emblem. Make sure the tune is fresh, and drive easy for a few tanks. The car will lean out through fuel trim...

As you know, it would tell a lot more.

The last one I saw (1JZ) at my track tore it up with a 15.1 @ 110 with a GT40. No, seriously. Way to represent. :nono: And he had a 5 speed. It bogged really bad. Maybe he just needed Jay to show him how its done.

So, mind your fuel trim. Avoid jackrabbit starts. Doing this, you will not get 30 mpg. I was on the highway, set the cruise to indicated 78, and my next stop was 370 miles away to refuel. That is how I got it. But you should be able to get 21-23 on a tank. If you drive hard expect the high...

Are there any widebands that can read CO2? Not to be confused with a 4 gas analyzer.

I can tell the difference between normal and sport. In normal, you start at the lowest level ( one light). As you increase speed, the second light comes on. If you are in sport, the second light is always on. So you wouldn't notice a difference from that persepective.

Yep. That was the point. On a street car, you should use a heavier performance rod. That is strong. They will live a lot longer.

Have you ever wondered how a car company gets 10 more horsepower without any changes?

I am often not sure what they mean. I ask what do you mean, and they don't say. Because somebody jumps in who speaks greasemonkey and tries to help. Oh well.

Or the 12.5 number is wrong...

I am curious. Why do you think it matters what he gets from MPG in an armored vehicle? ---------- Post added at 02:29 PM ---------- Previous post was at 02:27 PM ---------- Seems more like $1.50 or so on the high end. 1.25-1.50, depending on locale. ---------- Post added at 02:30 PM...

Another magical fix....
