Really? Interesting, it was very precise, and it was immediate, didn't work it's way too happening, pulled all the way to it, then boom, stopped pulling at all.

A number of 3000 swap owners have told me that when they rev the engine in neutral they start hearing misses at around 3000 -3500 rpm. I tried it and confirmed it, There is no problem there as the rev limiter is just kicking in when the engine is revved at idle. Not sure if this happens with the Fiero 2.8L ECM. ------------------

Very weird, just did this in first gear (eased into it, not full throttle), and it stopped at 6200 and resumed at 4000, definitely not what I thought I experienced the other day, I don't know, I'll have to do another 0-60 and see what it does in 2nd gear again

Never mind me, I'm stupid, the rev limiter does work conventionally, power "off" at 6200, back when it reaches 4000, it just doesn't drop rpms as fast as I expected, so when I was doing it initially I didn't wait for the rpms to fall before getting off the gas, hence thinking that it held at that rpm, oh well.

IMO, if you keep revving that old 2.8 up to 6200 rpm, you're eventually going to start hearing Jehovah Witnesses.

Haha, it isn't that old in kms at least, and it only has about a week of driving left before it is out of the car, and the 3400 will be getting installed, so I'm not worried, man, the 2.8 screams above 5000 haha, I may or may not now be addicted to rpm haha!

If I recall correctly, the 88 2.8L ECM does not have a coded rev limiter
