rev limiters

hey all
I was looking over the tech articles on 1G stuff and my impression is that the speed limiting is actually initiated from the dash not the ECU. Is this correct? and is the rev limiting done the same way?
My question arises due to the 1G-GTE conversion i have just done. i am running the 1G-GTE ECU but my dash so does anyone think i will have the rev limiter or speed limiter? is a very early gen 2 motor (air to air IC but yellow injectors). is there a way to check. i am not a fan of flooring it to see 
Thanks

Yes, it has a rev limiter (7500rpm?)
Speedo sensor comes from the dash cluster, it's a reed switch sorta arrangement... you can fake this easily.

are you talking to produce a speed output or to produce the limit output? my dash does produce the speed output and i don't really want the speed limiter on it i was just seeing if my car would limit just to be on the safe side. this may seem like a stupid question but it is really bad to hit the limiter isn't it? like i wouldn't want to do it much?
Thanks

speed limit and rpm limit are two very different things.
can i suggest you stick to a healthy rpm limit that's at the peak power output of the engine.
you hear race cars bouncing off limiters - but those are user-set and designed to protect the engine, not let you rev too high.
speed limits are at your discretion (and willingness to lose points on your license)

what i meant was that i don't intend to go anywhere near the speed limiter speed (its like 180kph or something right) so i couldn't care if its there or not.
But you didn't really answer the question. is the factory rev limit a "safe" one or just to prevent major damage. I also don't intend to take my car anywhere near the limiter it is all just curiosity incase i miss a gear and floor it in neutral or something. should i be concerned if i ever see the limiter? or even if i see it regularly

It's fun to bounce off the limiter every so often...

Rev limit for the GTE's is supposed to be set at around 7200rpm. Don't worry about this figure, because it's a good 500rpm lower than the 1GGE's. It was set lower by the factory because there is no point taking the factory turbos past that point, they are just a bottleneck.

Until you force them to work overtime, then it kinda hits the limiter with ease...

Also the 1G in your car will not have a Speed Limiter.

is it easy to just "change" the limit value? or is it a bit complicated to get it raised or lowered? i once took my 1G-GE to 7750 so i though it had no limiter, boy it wasn't happy about that....

i can't believe how many people use it!!! i always grew up thinking it was an evil thing only to prevent the motor blowing up when the throttle is stuck down or something. Not something that should be "tested" every week to insure its functionality lol.
I still plan on never finding mine, but its nice to know its there, now the fixing of my tacho has moved DOWN the "things to do" list

from my understanding bouncing of a limiter can create a lean condition.
aftermarket limiters cut ignition instead of fuel to avoid this and help protect the engine.

|
99% of computers, beit factory or aftermarket cut fuel.
Cutting ignition blows raw fuel out the exhaust valve and to some extent out the exhaust, which it highly illegal from an EPA point of view.
And lean is where there is just enough fuel to ignite, and it burns really hot.
If you reduce the fuel more, the fuel does not ignite, and therefore does not create a lean condition.

ha ha ha ..2SC and a rev limiter?? thats like saying my 18RG has a rev limiter..the only limit in a 2SC (non efi) will be valve bounce..and that doesn't sound pretty..
my 4age's hit the limiter all the time i took them out..thats why it's there for isn't it??
AFAIK toyota's rev limiters never create a lean spot..they advance/retard the timing 180 deg..thats why some times on a dark night you can see flames out the back of the drift pipes hanging off the levin!

I had a 2S-E hit the limiter once... in 2nd gear... after about 45 seconds of waiting for it to climb from 5000rpm to 6000rpm...

85 corona, hehe i generally change at 5krpm when driving hard it just so slow between 5-5.8krpm i hit 6.4krpm doing paddock work accidentally it hasn't died yet so can't be too bad.
They wouldn't put a limiter there is they didn't want you to reach it, i follow your motto.

The Cressida didn't.
I had taken it to 7200 on a couple of occasions, and record would be about 7600ish.

hears a note never get a good car serviced at a dealership not that anyone on hear would. When i did my advanced driver training course this year there was a ford and subaru apprentice mechanic there. They had a demo GT on the lot and had deleted the factory limiter which is like 6.2 and regularly give it 7-8rpm clutch dumps. Needless to say in its 10000kms they have already blown driveshafts and a few engine components. the boss motor have like a 105mm stroke
The subaru guy bragged about taking out any 2 door STI that came in.

I don't want to put a tacho in the wagon , I couldn't tell you how many times I've poped it off the limiter, it pulls all the way to the limit, without a tacho it sort of just arrives.
you get this nice bang bang and quickly grab the next gear.
Funniest thing would be when Jas (yellow rolla) didn't have a rev limiter on his comp. the good old 3TGTE saw 10400 the data logger read. haha when we poped the bonet at macca's we were expecting oil every where. But she held together.

man i can't believe this thread is still going, more like it should be moved to the general section and called "give us your limiter story" but its good to hear how "good" it is to use it. i still haven't taken mine out to far, i see what they mean by there is a bit of a bottle neck formed from the turbos as they seem to die off. but i suspect my clutch is doing a small slip in top end so i don't take it there out much
