has anyone successfully replaced a newer 58X crank reluctor wheel with a 24x one?
i know its just pressed on there, but exactly how do you align the throws and wheel?
what is the margin of error on the alignment? i know the CASE learn can compensate, but by how much?

Goodson Tool makes the tool to align and install
You heat the Reluctor Wheel to 450 Degrees- When it hits the cold
crankshaft it shrinks to it- You must replace the cam gear as the LS1/LS2
hardware is a 50% Dutycycle trigger. If you are tuning with LS2 Edit you
hit a wall at 11500 Hertz approximately 430 grams per second it will drop
to 0 grams per second- You have to go to that cell and plug in the last value
you seen (430 example) and put it in that cell. Now when the hertz goes
to 0 /0=430 or what ever the last air flow count was and the engine will
still get fuel for that air flow- as the rpm climbs you will tune in the PE/RPM
tables for fine tuning, a little tricky but works-- No problem with LS1- just
LS2- You will also turn off the Oil level as there is no provision on the LS7
We hit 496 Horsepower on our intial tune on the LS7 into 05 C6- Headers
and Tuning- I changed the spark plugs to Brisk, MSD Wires and doing some
port work on the throttle body Hoping to blast thru the 500RWHP Mark
Thanks to American Performance Headers (Vette Doctors) Katech -Torque
Specs, Ken @ Carputing,TPIS,& LS1 tech, I thank you and so does my customer! The LS7 is hard to beat what a rocket of smooth PoWER!

We've done it as well.. We have our goodson tool for sale if anyone is interested. Only used once!

Does it work ok? How much?

Anyone out there know the spec for the error that the PCM/ECM can address? I have heard +/- 3 degrees.

Thanks.

if the reluctor wheel is wrong the ECM cant correct it, it will just be wrong, throwing the timing of everything off. it needs to be put on correctly.

rsz288

Due to production variations and designed in tolerance levels, the ECM has a routine to learn the crank angle error and apply that error to run properly.

My question was whether anyone on here knows what is the maximum error angle the ECM can learn and adjust for.

Of course the objective is to install the reluctor to be perfect........

There's a bit of info here on using the Goodson RRJ-350 alignment tool.

Start looking after the 9th pic on the right...click the pics to read the info.

Then halfway down there is a blurb about "Exciter Rings"

Online bright and early in the west there today .

Interesting that there are two styles of 24X reluctors.

The index hole on the rear flange appears to line up with #1 & #2 rod journal/TDC.



.....24X & 58X alongside each other...



Have a good one...

Yes always bright and early for me. Where are you ?
You doing a conversion yourself ?

I've got myself a new spare L76, have collected all the parts to do a swap into my VX GTS someday. Crank reluctor swap will be done by a local performance shop for sure.

wow, that article was an awesome overview, thanks!

Reluctor swaps are reasonably straightforward. With or without the Goodson tool...but the tool is easier....less thinking. Pulling the crank is the worst part.

A few shops over Maddington way would be doing them with their eyes closed...

HSV-GTS-300

Yes and John will probably be doing mine too.
I think he and Dan have set up a production line.

Yah...the red rocks you guys over there are digging out of the ground and shipping to China are driving a real performance car boom! The Wild West! The ground just oozes cash!

This helps too.

At least one sponsor here (that I know of) is coming along for the ride.

Anyone know of a good workshop on the east coast of N.S.W able to do the swap over of reluctor wheels.I've recently purchased an L76 crate engine only to find out after i fitted it to my '02 VX SS that i need to change reluctor wheels over.
