having spot of bother as it were at the mo,

 

engine has been swapped, i used the NA loom tho still.

 

swaped the ECU, and fuel pump.

 

car has ben started, but i dont think fuel is getting there at the mo.

 

 

if you did the conversion,

 

 

did you use the NA loom, and did you use the NA fuel pump ECU?

 

i spoke to Jeff TT and im sure he said it was fine to use the TT ECU, NA loom, NA fuel pump ECU, and TT pump (even tho the NA pump is good enough)

 

 

just wana rule that out, before i think about getting a new loom.

 

only other possibility i can think, is loom or fuel filter

just had reply from that "ash" someone said about...

 

There are no issues with using the configuration you have in place. You have some other issue going on there. Have you done a pressurized intake leak test? (Boost leak test)

so now i know the pump setup i have is fine, i can look at the basics :)

Topless,

 

so you used the TT ECU & TT pump like me, just you used the TT FPCU.

 

what loom did you use? NA or TT

 

NA loom but recently my car ran lean so I am wondering if the NA FPECU is the way forward and getting a TT Map put on a NA ecu.

i sent an e-mail to DTA on here regarging that,

 

chipping/mapping the standard NA ECU, to provide enough fuel for the TT engine.

 

ive read you can do it, but when i e-mailed them they said no?

 

perhaps i wasnt clear on my request.

 

thanks tho mate, glad i know this isnt the problem :duffer:

Maybe there was a crossed line somewhere.

 

Like yourself I was a little concerned about the whole loom/controller/ecu issue a while ago, something unfortunately I never chased up.

 

IIRC I believe the only difference between the NA and TT ecu, is the ability to acitivate the boost solenoids to restrict boost in safety mode and the three speed fuel pump.

 

So in theory it should be possible to run a TT chip in an NA ecu, unless anyone can suggest otherwise?

i think that requires its own thread mate :)

 

il be watching it tho! rarther chip my NA ECU, so can sell my TT one then :)

Not really, I am pretty sure john dixon can illuminate us :)

Just for info, have done a bit of asking around and the correct route is either

 

NA ECU with TT chip----stock NA Loom----NA fuel pump ECU----TT fuel pump

 

TT ECU--NA Loom with third wire for the three speed pump--TT Fuel pump ECU--TT fuel pump

 

To install the interior TT loom would be too much hassle!

TT ECU--NA Loom with third wire for the three speed pump--TT Fuel pump ECU--TT fuel pump

 

 

think the third speed is very rarely used to be honest. speed 2 is efficant so ive read.

 

even the NA fuel pump itself is ok for the average Z, but i swapped it anyway.

 

 

yea i couldt be arst with the looms, lookt a bit daunting!

 

wish i took the EFI loom tho, as didnt realise its quite small and easy to remove (i had the dash off)

 

the loom i usedhad filthy connections, spent about 4 hours cleaning them. probably could have taken the EFI loom from the car in 1 hour

even the NA fuel pump itself is ok for the average Z, but i swapped it anyway.

 

Have to disagree with you there and it's a false economy to spend all that time and money swapping them, and not bother with the fuel pump.

not the same make of car i know but did an engine swap etc in an old mitsubishi i had ran the same as you have described would start idle low miss and run like sh*t eventualy found it to be an air leak on the intake manifold have you checked yours to see if any air leaks, wont be easy to hear on the zed engine so try a weak solution of washing up liquid and water sprayed around the intake gaskets and pipeing

 

hope this might help you out a bit

I doubt it will help 9 months later lol :tt2:

lol just saw this,

 

encase this thread gets digged up in the future, the answer is as follows:

 

 

TT ECU - NA Loom - NA pump controller - TT Pump.

WIth that setup the fuel pump will be oversupplying the engine the efficient setup is, TT ECU--NA Loom with third wire for the three speed pump--TT Fuel pump ECU--TT fuel pump !

Not really sure the comment "the fuel pump will be oversuppling the engine" is a technically correct description, the fuel pressure is regulated and the injector opening times is set by the ecu, any excess fuel goes back to the fuel tank via the aptly named "return pipe"

 

Maybe the fuel pump will be running a little quicker than it needs too, however I doubt it would have any bearing on fuel pump life or indeed engine fueling.

 

This is one of those many cases in life where the KISS approach is the very likely the best.

Ps KISS = keep its simple st?pid

LOL next thing I will be drilling new bracket holes for tension rods:angel:

 

Technically the fuel pump will be oversupplying the engine and sending it back to the tank, I didn't say it would be overfuelling the engine, for the sake of running one extra wire and getting a fpecu that probably costs ten quid, why not have the fuel system running as it is meant to.

"Technically the fuel pump will be oversupplying the engine and sending it back to the tank"

 

Thats what it does as standard anyway hence the return line
