Yes some engines are out of spec and need work but on the whole it's a compromise. You want quiet, go back to an iron block with steel pistons and then wonder why it's heavy and doesn't make as much power - LS engines are noisy and they have been since they were new. The alloy pistons to the...

Lack of refinement yes, but what do you expect from essentially an engine configuration from the 60's and 70's that's been refined over the years. It's not an advanced multi overhead cam European engine. A lot of people complain about the LS motors as soon as they start to make the slightest of...

Due to safety reasons, ECM's always use error correction and redundant memory. That's part of why they're typically quite expensive.

Definitely an ECU. P0601 is simply a module reporting it's failed an internal self-check. The troubleshooting guide for P0601 in any module is basically: check power and grounds. If all OK then replace the module. They are repairable through the right place though (injectronics if I recall may...

I suspect you've had backyarders work on your car. For starters, the cam and lifters should be replaced as a set according to the workshop manual. I would also suspect that if they've done a random "lets throw some lifters in it" then they've perhaps not used the right lifters. The lifters on...

Incorrect. There's a separate prompt for "Oil change due soon" or something similar with reference to engine oil. "Service vehicle soon" is a prompt used by a lot of newer Holdens (VZ was the first to use this if I recall) indicating an engine fault light that's non-urgent or non-emissions...

When you're talking such small numbers, other factors come into consideration. Big headers and big pipes just sound better.

QLD's wording is pretty straightforward though. Doesn't say "model variant" it says "model". So in this case make/model would be Holden/Commodore.

Check with a friendly engineer in NSW but with that wording, I feel good to be in QLD: 1.1 MODIFICATIONS NOT REQUIRING CERTIFICATION The following modifications may be performed without certification: -Fitting a manufacturer’s optional braking system for the particular make/model; So I bolted...

I don't have a HUD (standard SS) but none of the IPC functions work (e.g. the Nav page). The phone apps aren't provisioned for vehicle connectivity. A small price to pay I reckon.

The L77 is mechanically exactly the same auto to manual. In manual vehicles there is no provision for wiring to the AFM control solenoid and it's run as a V8 all the time. The later L77's aren't as common for lifter failures as earlier L76's but it still does happen, particularly more often if...

Does anybody know the PIDs to code an OBD gauge to read?

So you don't have headers to go with the tune? The 285kw HSV tunes had tri-y headers which were quite sought after for a bit as they flow pretty well. If you've got a tune not matched with the correct hardware of course it's going to perform like ****.

Throttle "lag" as it's commonly referred to in your DBW electronic throttle vehicle is usually a function of things like anti-thrash, drivability refinement and mechanical component protection. It's common in a modern engine tune to limit how quickly a throttle blade opens to reduce shock on the...

No it really doesn't. All it does is make applying the pedal 1-50% for example look to the computer as though it's 1-75% by fudging the resistances sent back to the ECM. It does absolutely nothing for opening the throttle body quicker or reducing throttle "lag" as it's not changing anything...
