    MS3 on a N/A M50TU

    Hey everyone, My brother and I have a 1970 Triumph TR-6 that is being restored in a pretty custom way. We have everything in the car, except for the interior, and the car is being painted next weekend, if everything goes well. We have a BMW M50 B25 VANOS engine in the car hooked to a Megasquirt 3. We have the stock coil over plugs with custom (homemade) ignition drivers. The car will idle, with some trouble from the ICV (I believe...) but it is a rough idle. We are using controlled vacuum leaks to let the car idle at a decent pace. We have an AEM wideband sensor for tuning. My brother should be typing this, as he knows more about this than me, but I need help coming up with a stock tune for a naturally aspirated M50. We have no ignition maps, timing advance, or fuel settings to go off of. I need one of you MS experts to help us out. If we could find the stock VE table and other settings from the DME, I think we would be set to get this thing running well. It will be a while before we can actually start tuning, but i'm trying to do my research now.

      I found this the other day, it might be useful as a base tune.



      But you can probably find better maps by talking to the guys on the msruns.com forum:



      or the msextra.com forum
