Im pretty shure we fixed it

Engine fires up like with ISA, engine backfires like crazy with the overrun fuelcut changes from erom and transition between the engine states is absolutely smooth. There was no real need for BMW to use the ISA...

Well eliminating the ISA also eliminates the turbulence intake system so I'm sure there will be some small drawback with regards to emissions.

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.

Good to hear I take from what you wrote that you didn't modify Throttle angle based on driver wish with the new changes?
The Y-axis is rescaled and the values have been modified to keep the throttle open under engine braking.

With the original Throttle angle based on driver wish values I gave you the throttle will be closed when engine braking meaning that you will be pulling a lot of vacuum.
So don't go crazy with engine braking if you are using the old values.

There is a small issue with high idle in some situations with the latest values so we will be doing more testing today.

Do you now the year and model of the Volvo? I have access to Volvos VADIS program so I should be able to find the part number for it.

I assume it's the detachable part of the intake hose between the airfilter and turbo (on the right in the picture)



Can be found in all s40/v40 with a turbo engine (2.0t and T4) between 1998 to 2004 the part number for the whole thing is 30620869.

But I'm having no luck finding a similar part on a 2003 V70 2.5t the pipe between the airbox and turbo is plastic on those.

Sorry if this is a stupid question but how do you re-scale the Y axis?

Edit: I think I figured it out, edit ldpm_pvs_3, correct?

Just tested this. Getting a good idle until I touch the throttle. Once I do it starts hunting between 1000-2000rpm. My tune has increased idle speed targets so I am going to try putting those back to stock to see what it does.

No difference. Perfect idle until I touch the throttle and then it won't stop hunting until I shut it off.

Has anyone tested if the 2 DTC suppression parameters and the two map changes that are documented in the wiki work on an otherwise stock tune?
