A mid 80's 3.5l motronic transplant is a popular modification. Anyone out there have ignition and fuel curves available?

Yes I am using a programable ECU and am looking for the curves (as in graphs) rather than just the values so I can compare with mine.

Re: Dyno Compilation

Thanks for this - some good info about the torque and hp of stock and boosted m30 variants. What I'm hoping to find is OEM or modified ignition curves, advance/retard curves and fuel enrichment curves - don't know if BMW ever provided those. Seeing this as graphed info will help in refining programing my ECU - I'll post mine when I've finished the plots tonight.

Have you asked for the extracted .BIN file from the MegaSquirt guys? They will likelyhave the extracted tables.
 
MS BIN File

I've seen lots of data logs (spreadsheets of numbers) but not graph's which for the digitally challenged have trouble with but I will pursue this. I have used the MS ll tuning download for reference.

Thanks for the suggestion.

what type of ecu are you using and what mods eg .cam, valves etc. i am running an autronic with a 292 deg cam, oversize valves, flowed, balanced. i should be able to get some information for you. cheers matthew.
