GZE Aftermarket comp issues

[craigy]

Hey Guys,

I'm in the process of wiring up an aftermarket computer to run a late model AE92 4AGZE, to be installed into an AE86.

I've got a large part of the wiring sorted but i'm having a issues with the ignition setup, and was wondering what sought of arrangements other people have used.

I'm using a v4 Wolf 3D and in the manual it has no diagram for a dual coil, single ignitor arrangement.

I'm chasing up some wiring details for the standard ignitor/coil pack setup. Including what each wire does what (signal, ground, +5v etc)

Also wiring info on the Cam angle sensor, including details of what wire does what. I have a diagram which has the CAS on it, but it does not specify what each of the wires does.

Also I'm assuming that the CAS on the GZE in a hall effect type? which requires a voltage.

Any help/experiences/diagrams would be fantastic.

cheers

Toyota CAS for waste-spark are reluctors not hall effect.

Good starting point for reading on the Toyota DLI system is http://www.autoshop101.com/forms/h23.pdf (434Kb)
start at page 9 for DLI specific stuff but the preceeding pages give you grounding in the technology. It does look at the 7mgte, but it and the 4agze work in similar manner.

Cheers chuckster,

Rep to you!

Open for more advice/info from everyone

how will it work with only one ignitor?

i had an idea to ghetto convert mine to multi-coil, was going to use 4 transistors and the standard ignitor (to allow me to use standard management)

have you called wolf yet? a guy i went to uni with knows one of the partners of the company, and drives an AW11 with a silvertop 20 valve in it, so they will have heard of 4AGEs before.

[oldcorollas]

and IRA11Y had twin coils on his 4AG, using the CAS and two bosch ignitors..

if it has a single ignitor now.. it MUST be a two in one to drive two coils..

call wolf

[craigy]

The original setup uses a single ignitor.
So I cant really see any reason that the computer cant use the same arrangement.

I havent spoke to wolf yet, I want to do a bit of research and get to know what I'm talking about before I call them.

I've read in previous forums of people using the original coil packs with 2 ignitors from a different type of engine. I think it was a Camira.

hey mate,
i went on the wolf web site and downloaded this guide. it might have some useful info for you.
should point you in the right direction anyways. check it out!

thanks for the effort, but I already have the Installation manual

u can get a bosch module which can have 1 or 2 or 3 outputs

so depending which way u go

i dont know why people dony run microtechs

they have the best diagrams and have have good helpdesk after 2 pm

if i get time ill try chase up part numbers of the 2 output ignitor

think the part number ends with 002

it has 2 inputsd and 2 outputs on one ignitor

u can also look inside the cas at the wiring

think white wire is common to all 3 sensors so this is the earth

then u have green yell and i think red

these 3 are the signals they are magnetic signals

u only need to use 2 of them

one of them is 4 pulses every 360 degrees the other is 24 pulses every 360 degrees

but does yr wolf have 2 outputs

someitmes there is 2 outputs but the manufacturer only fits a wire to ignition output 1

unless u do these regularly they are the biggest pain in the assssss

i can do a microtech with my eyes shut

[4agte]

mine is using the 4agze distributer with all but 4 or is it 5 of the teeth ground off and the stock gze coil/ignighter.

The teeth were ground off as the ecu wasnt getting a good signal and it was firing all over the place but aparantly you can fix this problem by buying a little black box from wolf that boosts the signal.

If i could get power to my ecu i could have got the map for you as i belive that wolf didnt even have a map for the 4agze but they sent my tuner a map from a 3sgte which they altered the values for the smaller engine

[sideshow]

if u fit an autronic to a 4agze u have to cut all the 24 teeth but one
u use this as a sync signal

the u use the 4 teeth as a reference signal

because not many people use these its hard to get the correct info

and this is also one reason why it costs so much to get it installed and tuned if they have problems

[takai]

All you have to do is use a pulse or wave form analyser. Such as a CRO. If you spin the dizzy at a constant speed then you can take a reading of the signals coming down the lines.

For reference, im using the stock 4AGE CAS (within the dizzy) and syncing off the 1 tooth Home, and then triggering off the 24 tooth sensor.

[roadsailing]

don't want to take craig's thread too far off topic, but:

sideshow, how well do microtech's handle Alpha-n configuration? (thats using throttle position and RPM as the primary load sensing for all those noobs like me) out there

we should have a thread to answer common misconceptions about ECUs, i might even go start one.

[sideshow]

well microtechs can be tuned either map sensor or tps
so i guess its all good just depends how good the tuner is
just remember map sensor is bit better way to tune it

the main prob is when people order a microtech they dont explain things properly

basically u tell them these details

engine type
dizzy type
how many coils
etc

and they will built an ecu to suit

so basically if u have a bitsa engine then u can still get an ecu that will wire up easily
and usually start first go

a wolf is like an autronic
it takes afew hours in setup time
and unless u have expo3erience and good mutlimeters or oscilloscopes to test signals
it make it difficult to find tiny problems

so to the peron with wolf probs
maybe try ringing any wolf experts in yr state
ask them what the dizzy needs
if it needs modifying then just pay them abit to modify it and ask them if it needs
a signal booster or reluctor interface

every thing else should be easy

basically all u need on the ecu is power earth injectors and dizzy to get enigne to start

theyre all easy but for the dizzy

[roadsailing]

reason i ask is that with big cams you can't use MAP as a load input due to low vacuum, air reversion etc, anyway,

/thread hijack off

[sideshow]

yer tps is fine
how big are the cams
i do run into afew engines that are used for the street with way to big cams
and are just so undrivable
but anyway just tune it with tps

[oldcorollas]

last hijack.. do the microtech have closed loop function yet??

[takai]

For reference, 308* cams with quads was a whole world of pain with the LT8 which i had. Ran rich as anything, and stuttered and popped until about 5000rpm. That was with the supposed best Microtech tuner in Canberra. Almost glad that it was stolen

Cf this with the Haltech which ran like a charm as soon as we figured out the dizzy

[JustCallMeOrlando]

last hijack.. do the microtech have closed loop function yet??

Nope, but I'd hesitate to suggest any of the lower ECU's have proper closed loop either.

[takai]

Nope, but I'd hesitate to suggest any of the lower ECU's have proper closed loop either.

What lower ECUs? Im pretty darn sure that MS&S has closed loop, as does Haltech, Wolf etc. Stingers and Links both have closed loop as well. Seems that Microtechs are the only ECUs not to run closed loop.

Anyway, shall we let this guy get back to the purpose of his thread.
