z6 wont rev past 3k! COME IN

[JDMJ]

So i have a z6 that wont rev past 3k and only cel is o2 sensor. Will a auto p28 ecu let it rev higher than that? Please reply.

[*EFilliated*]

If u have a 5speed then u need a 5speed ecu, I have never dealt with using the wrong ecu just thought it was common sense. Get the ecu you need, fix CEL, no need to be running around with one

[Black4DrEK]

Yea. you need the correct Ecu.

this one seems to be in "limp" mode..

Well, i dont have a 5speed p28 but did use a p06 and had the same issue. Changed injectors, dizzy, iat and still no luck. Changing tb soon to try new tps, maybe that will get me straightned out!

Yea check the tps that's probley it map sensor too I had the same probley but come to find out it was the wiring in my car where it plugs into the ecu my injector wires had been butchered and my number 2 injector wire was just chillin unplugged lol this is the built z6 right?

Unfortanly

Dang see you should have traded me for the zc :) lol jk man but its probley that tps I would change it asap have u boosted it yet? How many miles is on it now?

[cm7k24]

mine did the same thing this weekend at the track,
turned out my TPS was bad. changed it. and perfect again.

[JDMJ]

Tps didnt work, still cutting out at 3 and bogging. No, its not boosted yet and it has like 10 miles..tops. Not sure if ill have the cash for all plans, thats why i wanted to sell but i think its something electrical, not the motor. Not sure.

[Starrfire]

didn't you swap it into another car and it ran perfectly? Quit being a jewbag and put an o2 sensor on it

[JDMJ]

It ran good in jonathans car but never reved it. And I don't have a o2 sensor to put in it,

[JDMJ]

Got all CEL's fixed and still nothing. Need ideas guys!

[*EFilliated*]

so you are still running a auto ecu on a 5 speed motor? you fixed 02 sensor?

[JDMJ]

put a 5 speed p28, still didnt change.

[*EFilliated*]

ok well now u have a starting point, CKP,CMP sensors in the dizzy will cause a problem like this, any ideas if the dizzy is good?


put a 5 speed p28, still didnt change.

d-series.org will be your best friend It appears the Crankshaft Position Sensor (CKP) has gone. This common on Honda distributors with higher mileage. The CKP sensor is unserviceable; therefore, you need to replace the distributor housing. I recommend that you buy a genuine Honda housing and install your old Ignition Control Module (ICM) and coil. Have the ICM tested, because the bouncing tachometer rpm readings can be indicative of a bad control module

i wouldnt buy anything new unless i was 100% sure that it is what i need. Distributor King makes great DIZZYs found on ebay

I had a the same problem once, found out it was my plug wires arking. Make sure there isn't any moisture where the plugs go.

[JDMJ]

Swapped dizzys also, still no difference.

[EmminoDaGreat]

lol ckp sensor is not unserviceable, I take that shit apart all the time and swap them out with good ones... yes its unserviceable if you're a newb...


check
the
tps

like emino said TPS, look for a voltage change as you open and close throttle and something close to 5V at WOT, if u dont see a change thats a problem
