Turbo time!!

Is there any kind of a program to remap fuel and ignition using the stock dme?

I ask the powers that be for some assistance......the plan is this:

I now work at a shop with lots of parts lying around, and a dyno to tune, but what do I do about tuning the ecu? I have a friend to do the tune right, but the problem lies in getting into the ecu, and being able to manipulate the fuel & ignition values. Its gonna be a twin turbo (two baby sized ones) FMIC, thicker head gasket and slightly bigger injectors (?). We have the power....we can build it bigger...faster....stronger!
So is stand-alone the only way? And im looking for a very moderate power increase...not lookin to go overboard but maybe somwhere in the 250-300 at wheels.

Thanks ahead for all who ponder my query!

If I remeber correctly, you drive a 633/635, correct James?
Anyhow, if you dont mind me asking, why twins on an inline? Much more custom work and plumbing.
As for the engine managment using your DME, you could spring for a piggyback. A Greddy Emanage ultimate will do fuel, spark, datalogging, the whole nines. And, as for VANOS, I do not beleive it will control VANOS, but if I remember your car right, thats no worry.
Good luck with the setup, details! Let us know some details. This forum needs more activity.

Its for the 99 M3 actually...my poor old 633 is still in Alaska in a sad state

Im now thinkin single baby turbo also. Twin woulda been pretty sweet/custom, but the assembly/dissasembly factor is kinda bleh.(but could you imagine the power delivery?!? BANG!) And that leads me to the problem of keeping the vanos system active. If its switched at an RPM dependent scale, no worries as a stand alone system has other channels to set, no worries! If its load sensitive however, ill have to find a way to use only part of an e-manage. My friend at Blast Motorsports is still playing with the idea of melding a HKS fcon in there somehow.

And now being in california, I have to worry about getting pulled over and ref'ed.....gotta love bullshit cops with no time on their hands
