in the NA - TT swap im going to attempt to run the NA ecu with an electronic boost controller with a modified 3 wire pump to manipulate the correct fueling (first of all is that right/do able?) second of all (mainly because the guy doing the conversion assures me after reading this)

thats all ill need to do...... soooo all i need right now is an electronic boost controller, the one on my Rx7 was a single electronic solenoid..... do i need a twin solenoid? or a T peice to split the turbos? or can anormal single electronic boost controller take 2 inputs?

 

the guy recons i can get a second hand greaddy protec b for around £150, do i need it to have a pair of solenoids or will a single + t-piece suffice?

 

:)

(profec)

whats wrong with this?

You can retain the NA ecu if you wish, BUT you must have it rechipped with a TT mapped chip !! Do not attempt to run it using a stock NA ECU.

 

using the NA ECU (but chipped with TT Maps) allows you to retain the stock NA fuel controller, and then match it up with a TT fuel pump.

 

Single solenoid + T-piece. Twin solenoid EBC's is just increased accuracy thing..nothing to do with number of turbos.

 

The Profec B spec II is a great little Boost controller. Probably the most popular out there.

so if i can get hold of a profec specII its non specific enough just to fit?

 

also - iv just read this

 

 

NA to TT swap, no need to get an EBC

Just thaught id post some info, maybe usefull.

 

 

all the threads saying when you do a NA to TT conversion, you need to use an electronic boost controller,

 

as the NA loom doesnt have the connectors for the boost solenoids (without these conected youl be only on 7PSI)

 

 

you dont need the TT loom, nor do you need a EBC.

 

 

you can just wire them to an ignition powered live.

ive run each one to an earth (the engine)

 

then the posative just needs to go to an IGNITION powered live.

 

it doesnt matter which wire on the solenoids you use for the earth as their not polarity sensative.

 

dont run them to a constant 12+ tho, or as i have found out youl have a flat battery the next day

 

 

just thaught this maybe usefull info to the forum for future cases

 

 

 

 

 

- will i still need the na ecu chiping? if so, where do i get a remap i can fit a chip myself i did it in the rx7

Mmm....so easy to misunderstand whats been said in the link especially as far as the ecu is concerned. They (Z1) will "convert" the non turbo ecu for $250 to meet the twin turbo engine? well as twin turbo ecu`s are available for £100 or less that makes no sense except they want to sell you a "chipping" service for your n/a ecu at an inflated price.

 

So from our own experience use a TT ecu and do not worry about the fuel pump issue, all of the N/A to TT conversions we have done the ecu and fuel pump question has never been an issue.

 

Also using a TT ecu you can retain the turbo boost solenoids, just a single signal cable from the ecu, 10 mins work. Personally despite views against it we prefer to retain the solenoids even with a boost controller fitted for a few reasons.

 

Remember boost controllers are non engine / car specific and hence need to be adaptive so retaining the boost solenoid the duty cycle is less stressed and hence more responsive and also in the event of detonation the safety boost can still cut in, yes it will still boost more than standard but a lot less than if left disconnected, as a rule a boost controller set for 1 bar ( 14.5 psi)with the solenoids connected will reduce to around 10psi if detonation is detected, another benefit is the when the engine is cold you will still have the reduced boost level so not 14.5 psi when you make a quick get away in a stone cold engine...which is a good thing.

 

Keep it simple, the easiest way and the most reliable.

:detective:

 

excellent!! ok so, tt ecu, na loom, na pump

 

so the 3rd possition is not really required on the pump or ecu then?

 

can i just buy

this chip and throw it in the NA ecu? would that do the same thing as buying a tt ecu?

Mmm...25bhp increase on a non turbo, would like to see that proven.

 

Still say get a TT ecu and get the conversion done and working for say a month or 1k miles, once all happy just go for a chip and boost upgrade happy in the knowledge all is ok.
