4AGE 16v ITB's start issue

[Futo_gt86]

Is there a wire in the engine loom connects to the black/white wire that goes to your starter motor (not the main cable from battery)?
Coz you need one.
Starter sense.
Status is only has power when you turn the key for start/winding engine over.
Sends signal to ECU so it fires for coils and injectors

Dude your a Freaking genius!!!! it was a start sense wire and now its alive!!! well very rough but its alive =D

Here is that link to wiring up the 20v quads to run on a 16v ecu..

Ok so now i have it turning over but wont idle??? oh god, the petrol and lighter is looking good atm



Thanks matt, had a bit of a read but mine was already converted to ITB when i got it.

Where is the FPR vacuum hose hooked up to?
Do you have MAP senor?
If its a 16V MAP sensor ECU it will need one.
Is it running phat as, and sounds like huge cam?
Heavy smell of fuel?
If you don't have a good vacuum source for the Stock FPR is will fuel up big time.
When you disconnect the MAP it will just run rich as.

Its going to be a pig at idle with the Stock ECU and quads, it'll take some sorting and bit of patience

Keep at man, not to far off now!

EDIT: Be a good idea to wire up the check light to see what codes it on about, If there are major's try get it out of limp into open.

I have a vac sensor, yeah when it runs it sounds like it has massive cams in it, not a huge smell of fuel really??

really appreciate your help man =D

Ok so this might shed a little light,

I brought the engine from japan as a complete package (Motor, box, diff, tailshaft, loom, ECU and Apexi SAFC) so i was not 100% sure if the motor was running but was given a little collateral in cae it doesn't start.

i was told it was out of a running car when removed (Ex track car)


I will get onto this stuff today when i get up, again thanks Futo

Edit: forgot to mention, its not just a stock 16v with quads its has cams, n cam gears etc

[Futo_gt86]

If I had more time up my sleeve I'd come over and help you sort it.
The vacuum signal is going to be weak at idle with cams and quads, stock ECU is going to do some strange things.
I read you have Apexi SAFC, but didn't make sense to me as i thought they where for mass air flow meter (MAF) not MAP.
Can SAFC be used on MAP?
I haven't ever played with an SAFC....I understand how units like this work, but haven't ever seen SAFC in the flesh.
Was this ECU used with the SAFC, or did it have a different ECU?
Is SAFC still wired in?

[stixy]

Oh dude that would be amazing hahaha yeah im hearing ya about time =D

yeah this is how i brought the setup, with the SAFC and you can see where it was wired in, but there is still a few plugs i cant work out =/

I'm pretty sure it just lies to the ECU and makes it think its running rite?

[Futo_gt86]

I didn't know SAFC could be used with MAP, well there you go.
Yeah, it breaks into the signal from the sensor before the ECU, and you can adjust the value its send to the ecu by a certain %.
Is the SAFC powering up?
So, I take it there would be a wire from the MAP to the SAFC and then from the SAFC to the ECU sensor?
What have you done with the Vacuum nipples at either end of the quads, the ones you mentioned earlier?

EDIT: SAFC Instruction Manual
Scroll down list AE92 4AGE and AW11 MR2 4AGE
And list pressure senor

[stixy]

Yeah the SAFC is powered up, nah the only wires that are hooked up are TPS signal RPM 1 and 2 and Injector wire.

those nipples are free, i have not put anything running off them. that is just the 2 at either end and at the top of the quads yeah?

Yeah PR03 hmmm
