Porsche Motronic Tunning Expert
Hi,
I'm a Electronic Engineer by education and a Software Engineer by trade. I have reversed engineered the Bosch Motronic EFI system for the 84-89 Porsche Carrera cars. This same system is also used in many 80's early 90's BMWs as well.
At this time I have found all chip maps (100 or so maps) so I not only know howto alter Idle, PT and WOT fuel/ignition maps but also have solid understanding of all Cold Start maps, IAT and HeadTemp compensation maps as well.
Next I wired a Ostrich2 Chip emulator to emulate the EPROM chip, this emulator not only emulates the chip but has hit-trace feature that lets me know what cell within a map is currently selected in real-time! This means I can now live tune these cars on a load dyno!
I also piggy-backed a full WBO2 setup with recording feature, I can record and view in real-time the following parms:
- AFR
- RPM
- Intake Air Flow liters/second
- Cyl Head Temps - these cars are air cooled
- MPH vehicle speed
My interest in this board is to learn more tuning tips, particularly to tuning PT Ignition maps on load dynos.
Sal.
Would like to introduce myself
I've been on this forum for years now but didn't have time to do any seriouse tuning or any posting of course once I started tuning I realized I wouldn't be posting anything helpful because I had no idea what I was doing :confused:
Whit that being said I would like to officially say Hi to everyone and as I get into tuning a little more here I will probably have some questions so I hop some of you could help me out. Also I would like to offer my help I live in North Central PA so if there's anyone around me who needs help with anything just ask I do have a MAC Mentor scanner and have access to a Tech 2 if needed have built many of GM auto tranny's and going to be installing shift kit into my allison here in the next few days. I am also an Amsoil dealer (only for my own discount) but if you need anything I can get it for you cheap ;). So again anything I can do don't hesitate.
Thanks Everyone
Mike
