Ok, I did a DE-K swap into my 4th gen I30. I am still running a 4th gen. ECU but was wondering can i still advance my timing??? I know MaxBoost925 said he did his at the dealer w/ the nissan consult II but he has a 5th w/ dek. Can i use the consult II??? any info would be appreciated, thanks

 

Not if you're using the A32 ECU.

 

5th gen ECU is Flashable
4th gen is ROM, meaning you CAN do a timing advance on it, but the moment you turn off the car its gone. When you start it up its going back to stock base timing

EU will solve this issue

 

I don't know HOW many times I need to post this but it is not proven to advance timing at WOT. So it WON'T add any power past 2400 or so.

 

eleventybillionths time is a charm?

 

If people would listen and pay attention to what they've read, argh....

 

gee, maybe we should put this sort of important info on a sticky somewhere :-X

 

What are the neg./pos. to running a 5gen ECU. What would be affected possibly in a negative way??? thanks

 

well besides the fact u MIGHT have to do a full car rewire (not sure of the body control module can interact with a 5th gen ECU), the only real advantage is that its flashable (which like said earlier, the 17* timing advance thing with the consult doesnt do a thing at WOT, making that not worth it), and that it can control the 00VI by itself (which can be done with either an RPM switch or a VAFC... which makes it not worth it).

Bottom line, dont bother

 

The BCU and ECU do not interact ... I have done plenty of research in the full 3.5 swap department. Yes you will have to run all the wires, but that is what harnesses are for right?

The advantages are more than flashable ECU ... you get e-gas, better maps, VTCs.

VTCs are the MAIN reason for it. You lose a lot of low and low-mid range power (about 30 ponies minimum at peak ... tons of area under the curve lost)

oh and I forgot ... when you do the full swap, you do not have to disassemble the engine and swap timing components ... just plug in the main engine harness and start her up. None of that oil pan bull****, no drilling the timing case, no injector harness splicing.

 

This discussion is about the 5th gen 3.0 ECU (2000-2001).

 

oops ... I guess I didn't notice it was DEK stuff... sorry

 

So running 4th gen ECU on a DE-K is not worth it? I am ditching my VI since the motor is for a project car, and I would like to use a 4th gen ECU, injectors, fuel rail, lower manifold, harness. I wasn't aware the VTC is controlled differently in the 4th vs 5th gen - and drilling the timing cover? Can anyone shed some light on this?

At any rate, finding 4th gen parts (replacement ecu, IACV's, harnesses, injectors) will be easier than a 5th gen. I wanted the youngest block I could find, so I got a 2001 DE-K.

 

Worth it? Up to you. What they are saying is that the A32 ECU can not hold memory, that the only way to get a timing advance is to get an EB/EU.

A32 ECU + EMU(emanage blue, emanage ultimate, etc...) = what you want.

 

They were getting 3.5 swap stuff mixed up with DE-K swap stuff. No 3.0 has VTC's, and there is no drilling the timing cover on a DE-K swap.

 

That was my plan, emu and the maxima ecu. I have decided to use a 4th gen ecu and the 4th gen injector setup with my de-k longblock. I got confused by the comments hence my question.

So there should be no problem running 4th gen management with de-k? I wouldn't think there would be, aside from a few harness/sensor mismatches. I've read a few rumors or heresay about doing this, but nothing substantial.

 

Nope, been done many times. Just changing injector harness plugs, and things of that nature.

 

Why run A32 injectors?

 

Less things to change around during the swap? Less need for a tune?

 

u think it would be good to change to the a32 (260cc) injectors....?

 

I thought injectors were hard to find for the de-k top feed setup, however I found a thread yesterday discussing how the 350Z injectors are the same as the de-k injectors (different flow rates but interchangeable). That seems to eliminate that "problem".

However, 4th gen parts are a dime a dozen - yes there are a lot of 00 models out there but not as many. I dunno, maybe I am just making things harder

 

Actually, they're the same flow rate. I'm assuming when ever you saw them being compared, the Z/DEK injectors were using a different fuel pressure, so, use the same fuel pressure, and you have the same flow.

 

Tatanko, AFAIK, the DE injectors didnt work in an A32 LIM?

 

You either meant dek or a33 right?

 

Get a JWT like me....or do it the right way with EU
