My friend Steve posted what I am about to Reiterate..
This Civic came with a D16z6 engine and Automatic Transmission. They popped a timing belt, then replaced the engine with a D15B vtec-e engine. Didn't change Anything. Straight bolt in. Now the car Doesn't Rev past 4000 rpm's. What Is the ECU that Goes with this D15b vtec-e??
Another thing. How do i Identify if this is a JDM engine Or OBDII '96 or newer engine place in my obd1 computer system.??

 

on the front of the engine it has a block stamp. that stamp tells if you where it came from. also there is a vin tag on the back of the block. it will tell you even more.
the vtec-e i beleive uses a propriety ecu. an ecu that controls rpm because of the "E" vtec. 3 stage yes? some1 in the market place is selling a 3 stage vtec-e ecu..

 

Your ECU is in protect mode.

 

Do you have a engine check light?

 

No check engine lights

 

No check engine Lights I ran codes. No Codes....

 

The car runs and drives fine No issues what so ever but Will in no way rev past 4000 rpms

 

what ecu is in the car?

 

My engine code is d15b.valve coversays vtec-e

 

 

I have a p06-a02

 

My ECU is p06-a02

 

not even close to the correct ecu. usdm p07 will work, if your jdm d15b is actually a vtec-e variant.

 

Thank you very much eghatch9295

 

 

I found out this engine d15b with a head code p07-1 is actually a d15z1 motor... huh. What a pain in the ***..

 

ok, you need the p07. make sure you have the 5 wire o2 sensor on it, egr valve, etc. posting a pic of your engine would be helpful.

 

<p>This sounds so familiar to W95's car.&nbsp;</p>

 

I am going to Build a b20 block with a vtec b18c3 p72 head. Tired of this Tiny pain in the ***..

 

crap. i missed that it is an auto trans. there is no p07 at ecu. you may be able to have your p06 chipped to run the z1, but i doubt it. odds are that they re used the ex trans, the p06 at ecu will not run the trans correctly if that is the case. you'd need to start with a p28 at and go from there.
