It´s just "there" when you switch to that codeversion, it´s just like switching to any newer extra code so it´s nothing tricky.

I even loaded in my old 029q2 msq file, it did protest about errors in audit log but after i saved it and reloaded it again nothing went wrong. Although you should experience som need for remapping, since the calculation of the pw is more precise. Read the thread i was talking about earlier and you will understand that part...

The only difference you´ll notice when opening MT is that the numbers on the PW meter has more decimals....
Ok - and one more question, I "believe" my PW is = 2.0 or < 2.0 at idle. I have not log to look at right now but I do recall seeing that in MT. Would that cause instability of my idle afr? I forget what the acceptable minimum PW is.

Additionally, would using the Hi Res code still function with the latest megalog viewer and its VE Analyze function?
There´s no difference there.... the hi-res code works JUST as the latest 029 extra code, it just has the PWM current control taken out of the firmware and a 16bit PW calculator put in there instead of the 8 bit that´s standard, to put it easy, but all THAT info is.... in the thread i´m reffering to 8).

I´m not an expert on these things remember :) , but keep in mind that the opening time for an injector is "usually" approx. 1ms. And as i understand it the steps in PW is 0.1, which means that you at most would have 10-12 steps of PW variation in the idle area and that is not much. I think the hi-res code has 0.01 PW steps but i can be wrong there :oops: , it´s significantly higher in resolution anyways.

Read the hi-res thread..... i´m on the edge of ability to answer your questrions here :lol: .
