[fastM635]

I cannot find any tunes for this.  Is there a problem or are there no tunes for this?

I am currently rebuilding my M635 for the second time, first was in 1997 after I put 187k miles on it.
Previous dyno, stock euro engne 265hp at rear wheels at 6800 rpm.
I have bored it to 95mm and have the cams reground to 237deg at 0.050 with additional 0.01" lift.  CP custom pistons, 10.5:1.  cyl hone finish Rk=30  Rvk=42  Rpk=10

machining valve seats to original 3 angles, valves swirl polished, back cut at 15 deg intakes.  Stock valves.
 I am going to dyno tune engine on an engine dyno with war chip and gen3 maf.  Planning two settings, one for performance on track, one for street, compliant with epa requirements.

Any suggestions, tunes?

Hi,

We don't have anything specific for your set up. If you were to come to us for a dyno tune, we would start with our GEN III MAF tune for your ECU since it will actually be pretty good as a starting point.

I just want to clarify your concern though. Are you saying you can't see any tunes for the 055 ECU or just can't find once specific for your exact plans?
