It was over fueling tho.

also mentioned on page 22 of a genuine catalog. For the 1KD it comes to 145kw and 430nm.
Perhaps a reason why it is advertised as a genuine update over there and not here in Australia is due to the higher quality diesel over there. If dodgy, low cetane diesel isn't a real issue then I imagine they could provide a more aggressive tune for the European Hilux (similar in how certain performance cars require 98 octane).

This morning I threw the old duck across the rollers and confirmed a complete lack of change when the trim pot is set at 100% until it reaches 3500rpm(the settings are 80% Min- and 130% Max+ on the dial as quoted by Steinbauer for future reference). The information I have is that at 100% setting on the trim pot and under load the module increases the PW of the injector to 150ms, when set at 130% the PW increases to 195ms.
This should mean that at WOT (Wide Open Throttle) the pulse width should increase across the whole fuel map, Dyno results this morning proved otherwise at 100%. However at 130% this was true and I had gains close to Steinbauer's claims.

The vehicle is stock with 200K on the clock.
Legend:
Pink – Steinbauer disconnected from harness, stock run
Green – Trim pot set at 100% (vertical pointer)
Red – Trim pot set at 130% (full)
Going back to the information around the injector pulse width and how the module changes that, all runs were at WOT so no progressive acceleration and when you look at the 100% trim (Green) it’s clear it stays at the factory load table until 3400rpm before altering the pulse width.
Other than that, the increase at 130% is reasonably close to the Stienbauer claims of 19.1%. My engine at 95RwKW is not bad for a 200K old engine, an overall gain of 17.8% to 111.9RwKW. Although the amount of un-burnt fuel is horrific out the exhaust at that setting. I will leave it at 130% and monitor the fuel economy over the next two weeks.
How did your fuel economy end up after having the steiny on the highest setting?

I believe the turbo outlet is 2 3/4" can anybody confirm that spec? should have measured yesterday while I had access DOH!
IMHO most turbos will perform better with the least amount of restriction at the dump pipe, although some claim issues with over boost on the D4D, I believe that's more to do with the ability to close the waste-gate fast enough than an exhaust issue.
On a traditional (read old school, and I'm talking mid 80's -90's) waste gate we used to increase the spring tension very slightly to over come the problem (we also used to feed gas in front of the turbo to keep the spool speed up but that's another story ) . On the D4D its electronically controlled so not as easy to modify.
However a decent muffler in the system should be more than enough to overcome any potential problem. We are after all only talking about a max of about 4500rpm here not 9000rpm of gas flow. We could do the maths to get the amount of potential airflow but I CBF on a Sunday night.
I believe most of the limp mode issues we hear about are from vehicles running straight thru 3" systems where there is almost no restriction at all. I am not in favour of a complete straight thru exhaust, apart from the noise (signs I am getting old!) the difference in performance to having a muffler will be less than 1Kw. If you can feel that difference in your daily driving you are doing way better than me. And giving up 1Kw to avoid an over-spool and limp mode kicking in seems a fair trade off.
The only other solution would be to by pass the electronic control of the waste gate, you could use something similar to a sprint booster to speed up its movement, but its likely the stepper motor would fail a lot quicker with the extra load.
Irally you seem to have a bit of knowledge on this topic and welcome anyone else's feedback. I have a 2006 hilux auto and a year ago I had the steinbauer and taipan 3 inch exhaust installed. I had major issues on a road trip from Brisbane to Port Macquarie in NSW. It went into limp mode on every incline. It took forever to get there!!! After looking into several problems it' was finely narrowed down to the steinbauer unit. Steinbauer to their credit were very helpful and it was sent back to them for retuning and they said the issue was because of the 3 inch exhaust I was running so they made adjustments to the unit. I didn't think much of it at the time because while steinbauer were helpful I just thought they were offloading the problem. I rang taipan and of course they blamed steinbauer. I'm not overly mechanically minded so it's hard to work out who has the correct facts. Now it made a difference for 99% of the time however after just arriving home doing the same trip it went into limp mode twice. Generally around speeds of 80 to 100km/hr and going up a hill. As soon as I accelerated to hold speed it went into limp mode. Kind of scary when you have trucks up your tailgate. It's also a concern because I pick up our caravan this week and I'm worried under load it will happen more which puts my family at risk on the road. So the question is irally do I get a different exhaust or just disconnect the unit. I will be calling steinbauer tomorrow as previously they said if this didn't work they had another cable (I have no idea what it does) for $900 that can be connected that will 100% fix the problem. It's a gamble to spend another $900. Any feedback appreciated.
