well, pm me with specific questions if you want. i have 3 MS's, none on a car yet cos i haven't finished my damn PhD i DO have 4KE and 7KE setups ready to go on tho i have played with a couple of working cars tho.. Gareth with an XF falcon, and Brett with an Alfa 2L powered hot rod. i spent some time with them datalogging and doing a bit of tuning... the "Megatune" software makes it really easy... spent maybe 15-20 minutes with bretts hotrod to tune the majority of the power part of table... his engine (Bretts) has a very small range of MAP values, only from 75kpa at idle (25kpa vacuum) to 95kpa at WOT, as it's running GSXR individual throttle bodies.. everyone said it wouldn't run on speed density, but it runs fine. fantastically even!! http://members.optusnet.com.au/bcalv/myrod/myrod.h tm another one that comes to mind is Karl Skewes with a turbo'd 4AGE in NZ (garage dori or similar?) to get the (main) tuning software "Megatune", go to http://autos.groups.yahoo.com/group/megasquirt/ 'files' section, 'Megatune' folder http://autos.groups.yahoo.com/group/megasquirt/fil es/MegaTune/ and download "megatune216.zip" look up the "megamanual" which is a fantastic resource http://www.megasquirt.info/index.html basically, it has an 8x8 table of RPM vs MAP. these points are adjustable in 100rpm increments, so you can group them where you need them (in 3kpa increments in bretts case). it can do maybe 12000 or 16000rpm. can control at least 8 injectors with no worries. can do PWM to control low Z injectors and can do high Z injectors.. has closed loop mixture control, accel and decel enrichments, afterstart and warm up enrichments, automatic air temp compensation, automatic altitude (air pressure) compensation on startup, controls fuel pump relay and idle up valve (on/off type), ummmmm.... can use any temp sensors, but camira sensors are easy ($12 CLT, $20 MAT), has internal map sensor that goes to 150kpa positive, ie about 20psi boost. what else??? you build it yourself, costs less than $200, and is easy to install, set up, tune, and you'll learn a shitload about EFI in the process we are also just about to do our last Aussie GB before the UMS comes out. Australian MS yahoo group http://groups.yahoo.com/group/oz_ms Main MS yahoo group http://groups.yahoo.com/group/megasquirt Megasquirts are used on big US V8's, methanol drinking drag cars, turbo rotaries, turbo audi 5cylinders, harley's, jap 4 cyl bikes, 4 cyl NA and turbo, and also the worlds fastest 4cyl vehicle... http://www.yacoucci.com/gallery/albums.php http://turborick.com/video/ so yeah. it works. is stable. ppl have racked up many K's on them (Gareth is around the 14-15000km mark so far), they are simple to put together and understand.....
