hi again gav , yes thats what i thaught , but iv done my reaserch on them and the reviws from people with a similar set up 2 myself have not been over convinceing , and i heard a whisper that the aem would be a better option , ? i have basicly built the whole car from a bare chassis over the past 6 months without a problem until the final hurdle ,

 

its cracking me up

Are you talking about the AEM ECU? if so them mit has to be the specific part number for the n/a. 30-1101 as opposed to 30-1100 for the TT

 

no i was talikng abut the aem piggy back fuel ignition controller , but if they make a replacement ecu for the ge i could be interested , do you have any idea of cost

see , now thats what iv wanted to hear from day one , but so many people have told me the blue will be no good for my ge because it cannot retard the timeing and i risc pre ignition .

 

330 bhp is not a scratch of what the 2jzs are capable of so i thaught the lower end fuel controllers would suffice ,

 

but my current safc would not do the job because my map sensor wont support boost,

 

so i questiond the emanage blue and was turned against it ,

 

would the blue alow me 2 simply up the fuel under boost and iradicate my map sensor from throwing codes and cutting my fuel ?

 

bromy if you tell me it will , i will hapily take your word and go for one

You will have no problems with the blue. Nothing will control the timing on the n/a as it is a mechanical system unless you switch over to coil packs like the tt but that costs money.

 

Timing has not been altered on mine and I have had not one problem in over three years of doing my na-t conversion. You will however NEED larger injectors the 330cc are just too small

ok , so you use the blue and your happy so i will go with that, could you pleas tell me a bit more about your set up , what aditional parts you need with the em blue , how you delt with the map sensor , psi, afr , ijector size ect , all mutch apriciated

 

Fueling:

Walbro pump

Aeromotive FPR set @ 38psi

525cc injectors

Emanage blue with map sensor

No ignition changes

2mm headgasket

 

I am pretty sure the signal from the standard sensor to the ECU was not clamped but mine is OBD2. AFR's are how they should be on WOT (11.5 ish). Make sure you bang some NGK 3330's in there too. All in all it has been a reliable set up for me but make sure you find someone who CAN map the blue.

Didn't realise that the N/A was completely mechanical when it comes to timing control, however if that is the case, i am really surprised that none of you N/AT owners don't run into det problems, do you use a knock monitor, or det cans?

as far as i know aslong as you stay below 9psi on normal pump fuel whith the standard head gasket ther should be no problems ,

 

or thats what many others have told me

Just been doing a bit of reading, cos i thought the whole "mechanical system " bit didn't ring true, yes it has a distributer alright but its has igniter's and is ECU controlled, and so responds to advance/retard signals and knock control,

but i would still maintain that timing left as STD would not be ideal, and i suspect that the knock control may be getting plenty of work at 9 PSI, which is why i asked if any N/AT owners have dedicated knock sensors fitted, or use det cans?

I think there is an electronic signal sent to the distributor from the ECU, so it's breakerless ignition like MSD and Lumenition jobbies. But it's just the one wire. Theoretically the EMB and EMU can control that signal with the right jumper settings and ignition channel 1 tapped into that line to the dizzy, but as far as I know it's untested in the world of Supras.
