Which m20 motor is this??

[SpecM]

BUt changing guage cluster wouldn't stop my motor from over revving though.... Also what's a code plug??

yea, but it will remind you not to rev it (eta tach will have a 4800rpm redline)

the code plug is just a little white chip that plugs into the gauge cluster...

[slo325i]

nah, that wouldn't work either

you could swap the eta gauge cluster (and code plug)

[SpecM]

but would an eta chip just plug in the i ecu?? Would this limit the revs? will it even run?? Please help...

Hey guys,

I've been driving the car and it's running fantastic. No issues at all so far. But it just bugs me that I can't use the top half of the tachometer with this eta motor/ i wiring and electronics combo. And I'm always scared that whenever I feel like doing the "spirited-driving" I'll forget that I have be my own rev limiter....

Now someone here told me that I just can't go buy a eta ecu and plug it in there.... But would an eta chip just plug in the i ecu?? Would this limit the revs? will it even run?? Please help...

Just cause the rev limit on the b27 was only 4500 doesnt mean it cant handle higher. just means it doesnt have power past it. that motors a tank just like the rest of bmws motors. beat the balls out of it.

Your retarded! ^

The Eta motor has soft valve springs so don't rev it past 5k or valve float may occur and break the head/motor.

Also, to be sure its an i motor take of the valve cover and count your cam bearing, 7 for I motor and i think 4 for a Eta motor.

It just means it shouldn't be revved any higher, hence the safe redline, it's there for a reason.

I'm sorry but is this supposed to be a joke?? :(

haha, sort of. Kamotors already summed up what the "pedel dance" is

look for the CEL to flash in sequences, that will tell you the code

[SlowGoinE30]

You have to decode the stomp test.

I believe pelican parts has the walkthrough of it.

Hey-

Can you snap a couple pictures of the passenger side of the engine? Just want to see what valve cover it has.

[slo325i]

do a stomp test to get a code so you can find out why the CEL is on. turn the ignition to the point were all the power is on, the press the gas pedal 5 times, and the CEL will blink a code like 1222 or something along those lines.

Wow! Thank you for that info!! where am I supposed to look for the code?? the OBC?? or on the dash somehwere??

do the pedal dance?

I do have the CEL light on though. I dunno why??

Update:

I replaced the manifold with the b25 with all the accessories attached. Thanks to the gentleman who advised me to do so, I now have smooth start up and idle in the mornings. Thanks!!! I do have the CEL light on though. I dunno why??
