Hi, I'm Tobias who discovered the new ISALess settings. I'm running these settings on a 2000 330i manual with pre cat sensors only and I'm using the 430056 firmware. The idle usually starts around 1000 rpm when I have just started the car but drops down to the set idle speed after a couple of seconds as the engine warms up. Engine braking works for me, but it decelerates more quickly now without the ISA. So I'm sorry to hear that it's not quite working for you. Have you modified your throttle maps in any way? I'm using this throttle map in my car.


You could also try to reset idlespeed adaptations in INPA as I did that everytime I tried a new value for ISALess.

Hello Tobi,

thanks for registering I gave your first file a try and it works I needed to press the accelerator pedal to get the engine starting, so we may need to raise throttle angle at engine start. IŽll give your second file a try once the engine is cooled down. IŽll continue searching in the 430066 why its not working as in 430056

Daniel, what are the differences between those two files?

Hopefully I find some time during the weekend to try this out!

Ah okay! I edited my post on page 1 and removed the two other variables to prevent confusion.

Good to hear that you got it working on 430056 It's strange that you have to press the accelerator to start the engine as for me everything works like stock.

Did you try to reset idle speed adaptations?

But we probably should use your earlier values for throttle angle at engine start so we don't have to rely on the dme to realise that the ISA valve is gone everytime we need to start the engine

I'm planning to flash a completly stock partial file tonight with just the ISA fault codes suppressed so I know that no other changes I have made is affecting my results.

The second start gave me the same behaviour like you desribed Engine starts fine without any additional pedal angle.

That's really strange. Could you try with everything in ip_isapwm_at_tco set to 1.404 and see if that makes a difference.

I did and it has no influence. I also tried the other xy_isapwm_xy map and that has no influence, too.

Back to your file, no error delete and no resetting of adaptations and the engine immediately fired up without any problem.

IŽd like to work all the way through the file change by change. Shall we split it so that not both have all the work?

Just put some effort into this and modify your BIN file yourself.

It is really easy, just look here: http://www.ms43wiki.com/index.php?ti...n_Page#ISAless

I modified your file with the ISALess changes from the wiki.
http://speedy.sh/xcyxc/330-tuned-ISALess.bin

This should hopefully make your car driveable.

There is also more testing still being done on ISALess so more changes could appear on MS43Wiki in the near future.

Update at the wiki

Make shure the map ip_tps_sp_pvs looks damn similar to the one in the wiki!

It will hold the throttle open during deceleration to lower vacuum and therefore reduce oil suction through the valve stem seals.

Its also neccessary to do when using overrun pop/bang as otherwise the engine will not get enough air into.

This is a pretty neat find for the upcoming anti-lag implementation
