Andrew 30 Report post Posted December 18, 2007 Get the stock one tuned - it has fuel/timing maps in it (Assuming your Motronic - if your not then get motronic) Gaving Bellars @ Hi Velocity - does all the work on my cars (and very good work at that) and has seen some great gains of stock ECUs.

325_driver 422 Report post Posted December 19, 2007 so best bet just to get it tuned instead of getting a performance chip? will that do the same trick? but will it be back to stock again e.g. the same tuning 20 years ago. or better ? Quote Share this post Link to post Share on other sites
mr E34 11 Report post Posted December 19, 2007 Go for the real time tuning. I have done that with Map-Ecu, you keep your stock ecu and remove the barn door air flow meter. You are literally custom tuning your engine/fuel parameters that YOUR ENGINE likes etc.Any future mods can be real time tuned again to compare what your engine was doing before & after. If you check overseas you will find rolling road tuning the norm.(Bexeley motorworks in uk etc etc etc) Quote Share this post Link to post Share on other sites

These are the results i got by fitting Map-Ecu and real time tuning. Huge gains thru mid-range and modest top end, you have to remember my engine is 100% stock. Better throttle response and excellent Seat of the Pants FEEL. http://www.performancemotorresearch.co.nz/...hread.php?t=126 Quote Share this post Link to post Share on other sites
Creaver 55 Report post Posted December 19, 2007 When you say real time tuning, do you mean something like superchips? Who change the ecu programming? Or do you mean take the standard chip to a place and get it dyno tuned? Quote Share this post Link to post Share on other sites
mr E34 11 Report post Posted December 19, 2007 When you say real time tuning, do you mean something like superchips? Who change the ecu programming? Or do you mean take the standard chip to a place and get it dyno tuned? No chip change with Map-Ecu. Via lap top you can alter the fuel & timing while on dyno etc.(proffesional tuner) The lap top plugs in to the Map-Ecu piggy back computer, also you get rid of the primitive barn door flap AFM. Best to check out their full website. Quote Share this post Link to post Share on other sites

The tuning via laptop should be initially done by tuner, you can hook up while running and see the full 3-d map. This is the best you can get without going to FULL REPLACEMENT ECU/LOOM. Cost?? i would say up to $1000 depends whether you have Map-Ecu 1 or 2,(incl custom tune) Check out their website, N.Z. made/designed/backup etc. If you want to look at mine let me know.

Tuning can take a few hours but anyone with BMW M30 engine can now download my map from their site so you would only need slight variations to compensate for your engine characteristics etc.(you could drive immediately) Better economy when cruising at motorway speeds, no diff town driving.Don't know about co2. The good thing about map-ecu is you can hook it up in learn mode with your old air flow meter and it builds up a base map. Quote Share this post Link to post Share on other sites
