Reving past 8k

[Stripes]

I've got an s14 sr20, no tune, and I have gotten it to rev to 8k a couple times. It feels like there might not be a rev limiter. I'm using my kade gauge cluster, I dunno if it just reads wrong or what but I know I shouldn't be able to rev that high. Any ideas?

It shouldn't rev that high on the stock ecu, it may be worth pulling the cover off your ecu and see if it has been flashed/modded. If so it should have some type of a sticker somewhere.

Damn 8K is a lot.....hope you actually dont take it that high on stock valve train. But yea take the cover off and see if there is a small board with 2 chips next to each other.

Yup, stock valve train. I did it on accident, its not like I wanted to beat the f*** out of my motor. The first time I expected rev limiter to kick in, and I let off as soon as I noticed it kept revving. The other two times I just caught it late I guess.I had the ECU apart a couple months ago when I was looking into getting a PFC and it wasn't chipped then, so I don't think it is now.The only thing I could think of is the way I wired my fuel pump relay, but a friend of mine told me the rev limiter has to do with ignition, not fuel cut.

As far as i know the rev limiter on a stock SR ecu uses fuel cut not spark cut. I know cuz when you buy a PFC there used to be a model where you can use spark cut so to make sure you don't knock with high HP applications so maybe you did cut the rev limiter some how when you were changing the fuel system, but i really don't see how or know how.

Possibly. I would love to know where the wire I switched is supposed to run to, but I have yet to find a diagram that shows where each individual wire coming from the Fuel Pump relay runs to.The problem was my fuel pump was not turning on and I couldn't figure out why, so eventually I figured out that there is a black and pink wire coming from the fuel pump relay that is meant to be grounded. So I cut it and grounded it and then ran it directly to the ECU.So the only thing I can think of is, where ever that wire goes to is what tells the ECU to cut fuel at rev limit. I'm guessing that wire goes to the tachometer.... that's the only thing that would make sense, but I still don't know why that being connected would cause my fuel pump not to run.

If anything, I guess I could always get a Bee*R???

do you have an safc or an after market tach to hook up to it? May be the tach, mine went to 8200 on the tach, but 7600 on the safc.

Even if it was fuel cut your pump relay wiring would not matter, in a fuel cut situation the ECU doesnt pluse the injectors, it never shuts the pump off.

and if i remember correctly the ECU sends the tach signal to the gauge cluster, not the other way around.

No safc, that would be a waste of money.

But you sir are right about the fuel pump relay. I found a wiring schematic and the wire I messed with is wired properly, and I can not find any reason of why my limiter would not work. I did some research and I found out that Bee*R rev limiters cut ignition, not fuel, which is why they shoot flames (just a little fun fact). Anyway! Since I can't figure it out and shooting flames is always fun, I'm going to fix my problem with a Bee*R soon enough.Thanks anyway for all of your help!
