4efte trigger setup

Postby knightcrow » Thu Aug 26, 2010 4:53 am

i have a 4efte engine with a e6x and i'm thinking of using either a s3 or s4 sensor with the magnets placed on an aluminum wheel on the Camshaft .
- how many magnets to put on the disk for a camshaft pick

- What degree apart do i need to put the magnets

- and what degree do i need to put the home magnet south pole either before tdc or after tdc

- Which sensor is recommended s3 or s4

- i'm using the 5efe coil packs what is the dwell time for these coils it anyone know

and what is the ignition setup for such a setup

Get an s3 sensor. This is what I use all the time.
Now fix an aluminum wheel on your harmonic balancer
Fit everything in place and find tdc for cyl 1.
Now turn the crank 75-90 deg back and put the south magnet where the sensor is.
After put the north magnet straight across (180 deg) from the south magnet.

If you want to do this on the camshaft it is the same except you will need to use 4 magnets of total 1 south and 3 north 90 deg apart from each other.

thanks a lot
and this will allow me to run full sequential injection and sequential ignition or wasted spark

if you run it on the crank you can go for semi sequntial and wastespark.
if you run it on the cam you can go full fuel and ignition sequential.

i'm using the coil pack off of the 5efe which has built in ignitor is this constant charge or constant duty setup

it wil be constant charge, not sure on the time though, probably around 2ms.

Why don't you use the dizzy just for home signal?

I have a question on this same engine. a guy I know is wanting to use a Sprint 500 on this exact engine, does he have to fit a trigger wheel as mentioned above or can one just go off the distributor? What is the trigger pattern of this engine?

Thanks in advance,
Alberto

I have put a Sprint500 on one using stock Dizzy, 24+1 (usual Toyota of that generation). We blanked of the cap though and ran individual coils. Can't remember exact degree offset, was around 11teeth from memory, probably around 60 degrees.

Thanks Ignition, yeah it seems that the Sprint will be able to support that engine no issues at all.
Semi sequential on the fueling as well I take it.

Full sequential, Direct-Fire is what it runs :)

*with the Sprint500, not the E6* obviously - would be semi-seq with Dizzy as you stated with one of those.

I am looking for someone who has opened a Starlet 4efte ep91distributor. There are some four rooms where they discussed this to modify distributors for different engines and needs. I do not have that knowledge. My brother is an expert but he doesn’t have the information that Toyota didn’t provide for a distributor refurbishment.
The first time we opened the distributor to change the bearing and figure out which oil seal was inside we centered the forks that hold the magnets as the manual says. One by one using spacers with 0.3 mm per all 3 forks. The procedure is necessary to distance the points equally from the dented rotor. So the first time we closed it it works. The second time we opened it to replace the bearing that I finally found thanks to @RoyalDutchie we figured out that the big magnet was broken. It obviously happened while we was pushing out the pin from the camshaft side. It is unfortunate but there is no other way to get rid of it in order to open the distributor. So I was worried but we managed to glue it and thanks to my brother we could make sure within oscilloscope that the signal was fine. We follow the same procedure to close a distributor but this time it didn’t work. The pin out resistance is nominal. As well as that electric flow produced by the rotation of the dented arm So what has happened? There is no electronic inside but only magnetic magnetic wiring where the forks fit in to create the alternate electricity.
I hope that someone can help!
