8.1 crank and cam trigger settings for aftermarket ecu
 

Hi everyone from downunder

We do not have many 8.1's here so I am at a loss at what the crank trigger wheel and cam is at.

is it the same as ls1?

I am using a aftermarket haltech ecu so does anyone have a picture of the wheel itself? or know what the trigger system is ?

This engine is in a Holden ute (pickup) truck you would say.

I heard you guys like megga squirts? even a megga squirt tune file would be great!

any info appreciated

this is the coil on plug model not distributor

24X crank, 1X cam

Uses the same Crank sensor as an LS1 but I believe it is wired backwards from the LS.

it only made 216hp at the wheels through a worked auto.

does this sound about right ? the engine is standard.

using a dyno dynamics dyno which reads lower then the american dyno jet.

What are you using to control the engine?

Which transmission is it connected to?

Factory I believe was 340 hp 455 lb·ft of torque at the Flywheel. But here in the states depending on what it was connected to somewhere derated when connected to a 4L80E like in a suburban Vs. the same in a truck with an Allison.

Depending on your setup, that would be a roughly 36.5% loss through the drive train. I know the dyno dynamics can read low but I would have to believe the number should still be a little higher.

On the Dynos I have used, I have seen any where from an 18%-22% loss through the drivetrain on stock configurations.

it has a old Haltech E8 ecu in it.

I spoke to a few local guys and they are saying that the power it made is about spot on, it is a standard motor.

It has a T700 auto behind it

The guy has another engine that came out of a speed boat, can he put those heads on the truck block? would it make a big difference if he used those heads and got it ported and installed a cam?

I attatched a pic of the ute

cheers for the help
