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

are the fuses ok??

hmm good point, but no i havent,

 

ive had the car started tho, and its been on low revs, and died,

 

can hear the pump priming.

 

sounds like it wants to start but then doesnt. but it has been started since the conversion, but never idling running right :confused:

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

 

you didn't make the classic mistake of swapping the fuel feed and return hose, did you ?

at the pump isit,

 

yea im 90% sure i matcht them up correct, they would have had to be folded over if i conencted them wrong.

 

that is a good point tho.

>> at the pump isit,

 

no, at the engine...

Use the TT fuel pump ecu.

Use the TT fuel pump ecu.

 

no point, as thats 3 speed.

 

the NA pump ecu is 2 speed.

 

 

the NA loom only has the wires for 2 speeds, so a third wire would need to go from the ECU to the pump ECU.

 

Jeff TT has advised the car will run fine on 2 speeds. (hope!)

 

 

Lymon, il have a look at the engine, a possibility! i didnt do the engine bit of the swap, as didnt have a crane

I would double check with Ash in the US if I were you as he was doing a lot of development work on this?

if in doubt bypass the FPCU

...pump will run at full blow then, but could make it easier to troubleshoot if you are not sure if the feul pump controller works.

Sorry to hijack, Eric do you think the car will need a different map as the fuel pump will only be on two speeds?

the NA pump is good enough for TT powers, aparently good for 400BHP,

 

there is no need really to swap the pumps aparently.

 

 

in regards to bypassing the pump ECU, its still going to have 2 speeds coming from the main ECU regardless.

 

so unless its just a dodgy pump ECU, bypassing wont make a difference?

 

 

surely someone on here has done a NA to TT conversion & remembers what they did?

have u got e-mail or more info for him?

I can't seem to remember who has done one now:eek:

Marc, the pump speed does not depend on the fuelmaps.

the most important variable for pump speed is engine load.

 

The TT FPCU has a low, mid and high setting.

the LOW setting is used for cruising and idle conditions

the MID setting is used for 95% of all other conditions

the HIGH setting is not used very often and only in extreme conditions. (eg. very cold coolant temperature or very high engine load)

 

the NA FPCU only has a low and high speed.

 

I'm not sure if the LOW setting of the NA FPCU and MID setting of the TT FPCU have a similar voltage/flow on the fuelpump

 

If this is not the case, then the ECU should be adapted so it will switch the NA FPCU to the high setting in all cases were the TT FPCU would have used the MID setting.

Ok I suppose the only way to check is to get the multimeter out, and do some driving :) ?

just checked the serv.manual.

 

the NA runs in LOW mode at 8 volt where the TT runs in MID mode 7 volt.

So voltage/flow should be fine if you are using a TT pump and NA FPCU

While you have the page open ;), what voltage do the pumps run in high mode?

12 volt

and TT runs 6 volt in LOW mode

12 volt

 

For both TT an NA pumps, thanks Eric once again:bow::bow:

I installed the TT fuel pump, fuel ecu and main ecu.

thanks for that mate,

 

but what about the fact that the Main ECU (TT) gives out up to 3 signal speeds,

 

but only 2 speeds can be sent to the NA FPCU? as the NA loom doesnt have the third speed wire init,

 

as the loom only sends the 2 speeds signals, which the NA FPCU requires?

 

or is that irelavant

 

apreaceate your help! just wana rule this issue out of the non starting,

 

as if this was the problem, the garage would never resove it!

 

im hoping it is a basic mechanic fault like the fuel filter etc

I am 99% sure you are pointing in the wrong direction but I need to know the answer to this as well, so thanks for bringing this up.

 

Why don't you borrow the correct na componets to test your theory, the pump will prime as normal you don't have to fire it up just see if there is fuel there?

the pump is priming at the mo with the current setup.

 

teh car has even started! but idled very crap, and its a struggle to start it. and when it does start its on 400rpm and wont idle on its own.

 

car revs all the way out, but very lumpy, exhaust popping, which would suggest a fuel issue also.

 

 

i guess you could say i am using the NA components, as its NA loom & NA FPCU.

 

the TT ECU is required, for the more fuelling the engine requires, so cant put the NA ECU in. only thing i could do is put the NA pump in, but i dotn think thats gona make no difference.

 

 

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
