E-manage blue and ultimate questions


i-macca

Recommended Posts

Hi all,

 

Have had a trawl through the search and can't find definitive answers to what I'm looking for..

 

I've been thinking about getting an E-manage, either blue or ultimate, for my car and also getting a wideband and teaching myself some mapping (with a little help from somebody I who knows their stuff ;) ).

 

Thing is, I have a UK car and from what I've been reading, neither of these units will control the ignition on it? Is that right? If not, what is the reason for it not doing it?

 

Got some more questions I was going to ask, but have forgotten them for now :rolleyes: so will post them up when I think of them :)

Well i have heard of issues with getting the timing adjustment to work on the UK and the US TT, in fact on having a look on the Supraforums it seems that a couple of the guys on here are asking the same thing, is there some kind of fundamental difference in the ignition system on the UK model? i know that it has AFM and MAP sensor but i can't see why Toyota would go out of their way to change the ignition as well? i would be interested to know just what causes the problem, i'm afraid that i can't see that its just down to mapping, as that is just a basic! everything i have heard points to compatibility/installation difficulties.

Im currently researching the reasons why the emanage Blue Ignition works on JAP and USDM cars but not UK specs.

 

The ignition components are the same from the references to wiring diagrams i have been given.

 

What i cannot find is a genuine UK Toyota supplied 93+ ECU pinout Diagram

Toyota UK have been most unhelpful here :-

Though toyota Use the same Components, it could be something silly like IGT ECU pin assignment numbers not being the same, OR coilpack layout on the engine not being 123456 as the JAP and UK cars are, but rather like the VVTI 165432. this dos'nt effect firing order. but does affect which coil the igniter fires. If it fires the wrong coil the You dont get an IGF signal to the ECU - hence no start and an IGF code flagged up - apparently the outcome of Matts install??

 

The only diagram i can find regarding pinouts, is either the Original MKIV.com diagram or one which has been copied from it. On this diagram corrections have been made to the IGT pinouts...id like to know if this could be because the Original referred to UK spec pinouts but they differed from UDSM.

 

I would also like to get my hands on an Original UK Toyota supplied ignition wiring diagram...so if any anybody can help...lemme know..

 

How many people have actually tried to use the emange ignition (apart from Matt) on the UK TT??? to eliminate the fact that Maybe Matt had a dodgey Harness, Igniter, etc etc

The reason im asking is the good old chinese whispers syndrome, i was told it dosnt work so took it as gospel for all off 3mins then said, BUT WHY? if theres a will theres a way :-)

Mohd says it works - but he would, he sells it. Im prolly gonna do a trace from the ECU to the igniter main plug Which has 6 IGT lines in from the ECU and 6 IGC lines out to each coil, and see if the IGT-IGC relation is the same as the USDM wiring diagram.

 

toyota have been no help and say they cant give me the UK wiring diagrams for the ignition system, or ECU pinouts, instead they send me to

 

http://techdoc.toyota-europe.com/

 

where you have to pay - and guess what? they dont have the supra info online lol

 

Is there Anybody on here that works for toyota??

Just found the VVTI ECU pin out diagram and i can see that it runs grouped igniter outputs, and the only US/UK pin out diagram seems to run individual igniter's just like the J spec, so like you say unless the order has been changed, in which case it should be relatively straight forward to trace it through.

Just seen this, my reply notification didn't work for some reason :rolleyes:

 

From what I've read, it's not down to the mapper as to whether they work on a UK car or not. And I understand the fuelling does, just not the ignition and nobody is sure why not. As Bondango says, it may be down to Chinese whispers.

 

I'm also not sure if this is just the Blue or the Ultimate or both?

 

I'm very tempted to get one of the above and spend time playing with it, being able to adjust the fuelling would be great, but timing as well would be a real bonus...

I've tried both an EM Blue, and an Ultimate on two different UK cars and both cars refused to fire and showed a fault code 14. Ignitor.

The only thing both cars had in common was that they were both early UK cars. Not that I can see that would make any difference.

 

But if anyone figures it out, let me know what I did wrong :search:

Matt and I have looked into this and neither of us can work out, yet, why the UK specs won't even start if the E-Manage's ignition lines are in the loop. No UK spec car we've looked at likes it and they all behave the same way (turns over but no spark).

 

I'm pretty sure it's not the map :innocent:

 

I've had a Blue and an Ultimate otherwise working on UK specs no problem.

Ian thats why i would like a Genuine UK supplied TT wiring diagram for the early UK models and a Pinout diagram. Just to eliminate and differences between the UK and jap spec's if there are any. Early UK specs may have used different assignments to pins 52-58 for instance..Something simple like coilpack layout or igniter channel differences would cause the code 14, also a simple test to make sure IGT signals to igniter get a 5v, 12v or are to pulled ground which would mean changing the emanage Hardware setup.

Well one theory im looking at is definately ECU pinout assignments.

 

If you look at he following, it refers to the Jspec and USDM

 

Emanage 1 2 3 4 5 6

Channel

 

2JZ-GTE 1 5 3 6 2 4

firing order

 

Control line IGT1 IGT5 IGT3 IGT6 IGT2 IGT4

Ref

 

Igniter 1 8 3 7 2 9

Plug Pin

 

Ecu 57 53 55 52 56 54

Pin

(claimined

for US)

 

 

 

Now if for instance Coil pack layout on the Early UK's was not 1,2,3,4,5,6 but say 6,5,4,3,2,1 Then you would get a no start situation as the ECU wouldnt recieve an IGF confirmation when it first sends a Signal to the igniter, as it will be trying to fire to the wrong coilpack.

If the Pinout Assigments for the IGT control lines wernt that of the Jspec and USDM you would also get this situation, as the ECU would be expecting an IGF conformation that the correct coil had sparked.

 

But without the relevent Information its a very long process of elimination

This could be the reason why mine don't start (J spec car with, which I think now is a UK spec engine and loom, I think!).

I originally bought the car as a non runner, blown motor which I rebuilt, the inlet manifold had the EGBV gubbins which I removed, isn't this only on UK spec cars?

 

Sorry, no it can't be a UK loom as it didn't have the plug for the resistor pack which I had to hard wire in.:confused:

Ok another bit of research today..

 

The following Igniter was run for the first 5 months of Production on

UK cars

IGNITER Part# 89621-22020 93/05 - 93/10

 

After that, they changed to a New igniter

IGNITER Part# 86921-22030 93/10 -

 

Now, it would be interesting to here from those running EMB ignition control on Jspecs, What is your Igniter Part number??
