my 1985 325e redlines at 7000rpms

[goodboyz358]

i figured it all out guys. sorry for the time wasted. and mistakes i made but i took the code plug out and the tach is reading much differently and making more since. fuel cut is around 4250rpms sounds about right. its was the code plug in the cluster the whole time. im just going to leave it out

I dunno but mine does this and I have a friend tht has this same thing on his! But I doubt his is chipd! I've taken the head off a couple of times and haven't noticed anything different! My friend mentioned tht I may have a different crank...... But hey even he said it wasn't possible for I to rev-7000s, and it's doin it.:crazy:

[goodboyz358]

guess i wanna find a chip now. like mark d or something

[goodboyz358]

all i have found on the plug is 56. but when i took the plug out. the rpm read different and i bumb the gas and it hit 4500 rpms

The coding plug should have a BMW part number on it. Plug that part number into realoem.com and see what car its is used on.

[goodboyz358]

the coding plug has an 03 on it

i read it was physically impossible for a stock eta motor to rev that high.

with the revlimiter disabled, it is physiclly possible

but it wouldn't do it but a few times ;)

If the cluster has a 4 cylinder coding plug the normal 4800rpm rev llimit would indicate as 7200rpm on the tachometer.

its just a I cluster with a eta coding chip. no way that engine is reving that high.

^this.


my 88 528e revs to 5300 and it sounds much more wound up than your car.

actually the eta red line is something like 4800 but this is still interesting. mine is chipped and still, at 56 or 5700 revs, she's a screamin. i cant imagine what an eta at 7000 must be like. dont know how the rev limiter works though. is it done by a chip in the ecu? and if so, is it the same chip that we replace w/ our performence chips? anyone want to chime in? corect me if i'm wrong, but if it's a real eta, the ecu will have a number on it ending in 027. if any mods where done the ecu would of bin swapped out too right?

[1fastETA]

Mine does the same thing, but I know mine has a chipd ecu!

Damn chip+I valve springs? Pop the valve cover and check for double springs. If that indeed is 7k...lol if on eta single spring.

i checked the computer. i dont think its chips. its got a nec 1767355165 chip. and ill pop the cover off tomorrow too late its 2:13am here. im east coast. ill check but its hitting 7000. cause it dont sound like its stoping at 4k. just keeps going til 7. something not right here
