ISL tuner: STEINBAUER

Has anyone used a Steinbauer tuner?
I have a 2002 ISL (370 HP) and it seems options for increasing this CAPS engine are slim.

Steinbauer advertises 20% increases and shows data from an ISL 400 that is actually closer to a 25% increase.
It is an Austrian company

Just make sure your tranny will take the extra torque.

The way I understand it, the max torque doesn't change substantially.

Supposedly, it keeps the torque up (flattens it out a bit) up into the RPM range instead of dropping off like the stock ISL curve.

Run a search for this and read the results. I just read about 5 websites, they all-including mfgrs. website, say it works by extending injection timing width = uses more fuel. This causes the combustion chamber to run hotter; there are many negative ramifications from hotter combustion chamber temperatures.
Do your homework before spending over $2,000 and possibility melting your exhaust valves.

I have read quite a bit, but there is still a lot more to go.
One curious thing is the claim by most tuning systems, that actual fuel economy will improve (supposedly improved combustion efficiency) with their tuner. I have always assumed that for this (improved combustion efficiency) to happen, the air flow must increase, leaning out the mixture in the chamber, thereby lowering the overall combustion temperature (and EGT's).



I have looked at HDT CAPS system, AG-Diesel (Brazels represents them), and Steinbauer.



There are many more options for the 2007+ ISL engines, but for us CAPS owners, it seems there are just a few.


There is a significant amount out there on AG-Diesel and even on HDT, but very little on Steinbauer.
Hence the question about the Steinbauer tuner.



I am guessing by responses so far that no one here has experience with (or maybe never heard of?) Steinbauer.

Yes to Agricultural Diesel for CAPS era ISC/ISL's... This was the one I would have tried if we had kept our Allure with the ISL370(400 programmed by Cummins).

Do not have any info on the one you asked about...

Best of luck to you,
Smitty

For peace of mind, would install a pyrometer with any performance upgrade.

For sure, many people who drive with their foot to the floor at low rpm going up a grade, would be surprised how fast and how high the temps can go.

I have a pyro and also a boost gauge in my plans.


Here's my proposed layout:



All gauges are in the stock location except the newly to be added pyro and boost gauges on the right

I think I have decided that the ag-diesel is my best choice.

I do like the Steinbauer, but the cost (a LOT more than the ag-diesel) and the fact that it is relatively unheard of in the US has swayed me toward the ag-diesel.


I would like to install it myself, but hopefully will find a dyno in central California that can do a before and after comparison.


QUESTION:
Will my silverleaf still work (accurately) with the ag-diesel unit?
