Hi Everyone, (Long post ahead)

 

Firstly, I'm astound at the quality of information on these forums and have helped both myself, and my mechanic/tuner with several issues we've come across through the stages of building up my Supra.

 

I would like to know the procedures of joining up as a non UK member.

 

I've owned my Supra for two years now and only just recently gone single turbo! :D

Custom made stainless steel exhaust manifold

Garrett TO4Z with a 0.96 A/R

Tial 44mm external wastegate.

That's all I can think of now, so here is a before and after photo of my car:

I dont have any power figures as yet but I made 196rwkw when it was stock, and 237rwkw with BPU at 16psi

 

We are currently tuning the Emanage for the single turbo setup but we have run into some problems.

 

I have done some searching, and sounds just like what Ian C encountered when he tuned his EMU for the first time.

 

Here's what we've done so far:

 

The EMU was wired up with an Emanage Blue car specific harness and a supplementary harness thus making it a Emanage Ultimate harness for the 2jz-gte

 

The car started up and idled perfectly with the stock 440cc injectors

 

The 800cc injectors were installed.

 

This is where the Emanage Ultimate started causing problems:

 

It would only start with an injector lag time set with 440/0.9ms and 800/12ms as the parameters - which of course, is way too rich, takes away close loop and takes highway driving out of the picture.

 

So as the car is running, my tuner would trim it down to a better idle - then turn the car off once it has warmed up. However, the car won't start again afterwards.

 

So we decided to try to run a PowerFC to see if it was the injectors or ECU that was causing problems - alas, the car idled and ran perfectly with the PowerFC plugged in.

 

So we then decided to install the Injector Adapter 2 last week, but it still didn't rectify the problem.

 

Does anyone have any idea what we could have missed or have done wrong to cause this happening?

 

Is there anything that we could have possibly simply missed that's right under our nose?

 

I'd really appreciate the help, thanks!

Hello and welcome to the club :)

 

I had exactly the same issue (although was using an emanage blue, not ultimate).

 

It was only resolved after moving to a Power FC any making some huge corrections to the injector lag time (I'm using flow tested Power Enterprise drop in injectors)

 

From what I've heard here before the Sards can be a nightmare and very mis-matched from the factory, did you have them fully flow tested prior to installation? What were the results?

It's an absolute must that you have injectors properly flow tested (not just cleaned!) prior to fitting. Get them out now and have them tested to ensure they're all providing equal flow.

 

There's been plenty of stories here of injectors (even ones much higher quality than the Sards) being out by 20% or more. Some have even been found to lock.

magictorch: The first photo was taken at Port Botany which is just around the corner from Sydney Airport.

 

My tuner took the injectors out today to have them flow tested, and he reported that there was nothing abnormal from the results.

 

We used the same parameters and injector lag times on a borrowed powerFC, and the car started in an instant and idled perfectly - which is really mind boggling.

 

I know for a fact that 800cc injectors can be used on the EMU in Supras as I have seen it been done countless times, so why can't it work in my instance? :confused: We have checked the wiring of the harness three times now and cannot find any fault in the wiring. Is there possibly anything that we have forgotten to do or we missed in the process?

 

It's just so bizzare because the car started, idled and ran fine with the factory 440cc injectors

 

P.S How do i join up to become a club member as an overseas user?
