All,
Can anyone give us some detailed info about the ECU on the 95 V6 LE w/Auto tranz?
Does it have a built in Rev Limiter and at what RPM does it come on?

When manually shifting it seems to go way beyond the factory Red Zone on the tach (6200/6400) like 7700 RPM and it seems like valve float and not ignition which is limiting the RPM.

Specifically I am looking for published data about how the system works or should work, so feel free to include manual trans info if that is what you have but mine is an auto.


Thanks,
/Randy

I have been going through the repair manual that is stickied at the top of the forum and can not find anything on a rev limiter. Of course taht is probably not waht toyota calls it so trying to search for it in the PDF file is not the easiest. I am sure there is I jsut dont rememerb from when I was working for Toyota. It never really came up when I was working on them.

the 1mz-fe in my gen 4.5 rev limiter kicks in just as you hit red

I wont let you go much into the red if at all. I've hit it before. And it feels hella strange when it does. The car like stutters. ie stops accelerating and once it drops it lets you go again

good to know that you cant break your engine by being dumb =)

The 1MZ's have both ignition and fuel cut. It should be around 6800RPM to be exact, although some of you may see it go higher because some tachometers read quite off at higher RPM. The rev limiter will engage a soft cut ignition rev limiter, similar to a very sluggish feeling of the engine, and eventually it hits a hard fuel cut like hitting a brick wall.

Where did you get the info?????

Tony,
You posted some facts about the 1MZ rev limit. Can you tell us where you found this information?

Also the info posted on your rides - some serious numbers there! - any info we can read up on and see how you got those number (FWHP)?

The CCH website has head flow numbers for ported heads. Do you have the stock plenum, intake flow numbers? Also the stock cam numbers. I can't seem to find them lift, duration, open/close events....

Thanks,

Randy

Whay are some of you guys redlining your engine while not in gear? That is bad for the engine. I've nevar gone past more than abut 3500 rpm, and that was along time ago when i first got it.

Whats the difference? IMO, theres more damage being done while under load, seeming the engine is "working" hard at the speed, as opposed to just free revving.

^ plus the power on the 1mz starts at about 3500k, so basically, you aren't going anywhere fast until you go beyond that point

^^ True that! nice an sluggish ride if you dont go past 3.5 =P

'cept unless i and trying to go fast, i usually let it change at about 2.5 - 3 hahahahaahah

Its better economically with rising fuel prices

It's like dry firing a gun or a bow, no load causes inertial stress. Hard to explain.

You will have to call CCH directly to get the stock flow numbers... He didn't put them on the website and I don't have mine readily available (lost my old HD).

The rev limit info was found in the Toyota shop manual, specifically for the 1994 Toyota Camry V6 (comes in two huge a$s books).

Free neutral rev redline will be different than say your car is moving. My stock ECU'd Camry back then would cut fuel around 6200RPM in neutral, but would go close to 7000RPM (6800RPM to be exact based on shop manual) if the engine is in gear and moving.
