here's an interesting note plutonium. The tps switches used on the e34 cars motronic 1.3 and 1.2 are actaully full pots, however bmw ecu only uses the idle/wot switches. If you look at the wiring there are no wires going to the rheostat pins. I found it really weird at first when i was wiring my M5 ...

I'm sorry, i didn't mean to say that you had to use maf, you just mentioned that you wanted to use a MAF conversion.

Ofcourse to start out I would use a MAP as it allows you to learn the system without having to worry about a MAF. However I've noticed in my few hours of playing with my MSII with ...

hey plutonium, MSII as it is right now fully supports all bmw sensors, I'm currently running the same motronic version in my MSII v3 piggyback to a stock 1991 M5 motor, which uses Motronic 1.3.

However my motronic uses a MAF instead of VAF. However, if you're going to convert to MS then just get a ...

um, yeah higher number means lean, rich would be like 12:1, you're running WAAAY lean...

as in more air to same fuel... 14.7:1 means 14.7liters of air for 1 liter of fuel, ratio. So more air in there would mean leaner. You've got the rich/lean backwards

oh, duh, lol oops. thanks, i knew that too, however totaly forgot about it.

Hey guys, so i just got a new LC-1 wideband o2 sensor from DIYAutoTune.com. Seems to work great, however i'm having a weird thing happening, the manual says that it works on a 0-5v on it's 2nd analog output, i configured my MS2 v3 2.67 to work with innovate 0-5v wideband, however my lambda gauge ...

yeah i already did that, i set my reqfuel to 7.2 from 14.4, and scaled the ve table by 2

Now i just need to figure out how to use the alpha-n/SD blend, the window isn't documented yet lol. My map is way too sensitive, and sometimes since the ecu cracks open the idle valve, it sticks in the "out of ...

ah, thanks that's what i thought.

Since it's a mathematical formula, i guess if i lower the reqfuel/2 then my VE values should be *2 right?

thanks

I'm sorry cossie, i'm not sure i understand what you mean? If i add +10 to the whole table in the table editor, won't that just shift the table numbers +10 and make my car run REALLY rich? or is there some sort of multiplier i'm missing.

Thanks

Thanks

Is there a way to lower sensitivity on the VE values? while i'm revving it at say 2000, at 65kpa or so, the mixture is rich at 35, and it quickly goes lean at 33, however 34 seems to sway either way... how do i make it so my VE values are less sensitive, say add a multiplier of some sort to ...
