Summary of change:
I frequently repair Honda racecars, install stuff, do maintenance and tuning. Although we are quite well off with all mechanical, air (intake, exhaust...), hydraulic (eg. VTEC) systems, we are often short of good tunable ECMs and tools. I started to browse around [http://www.pgmfi.org/twiki/bin/view/Library/TuningConcepts pgmfig] which is a nice site.Unfortunately I speak only a little English, I get some help from time to time with English and internet. ---- '''Current engine projects''' * Honda Civic VTI 1992-1996 SR3 B16A2 engine OBDI MembersPage/GeorgSzabo/HondaB16A2 * Honda Integra Type-R with B18 engine OBDI (OBDII?) * Honda Civic Type-R with K20 engine OBDII To my knowledge the above OBD# are correct. There are some [http://www.pgmfi.org/twiki/bin/view/Library/DataLogging datalogging] related info (the wiki part of pgmfi site is great). From [http://www.pgmfi.org/twiki/bin/view/Library/OBD1CN2 this page] it seems it's a simple serial port with non-standard baud-rate and [http://www.pgmfi.org/twiki/bin/view/Library/OBD1J12 some hack] needed. '''I wonder if the Uberdata1.70.zip can tune or only monitor.''' It seems that only monitor, and EEPROM swap is needed for tuning. Can someone provide info on logging and tuning the above ECM-s (maybe pgmfi.org links) ? Thanx. ------------------------------------------------------------- Stick with Uberdata for your hondas. - Nick What do you exactly mean ? That uberdata can be used to log the engine, or even completely remap ? Or maybe more ? Control over knock-adjust? Does it have closed-loop WOT capability with any Honda ECU? ------------ uberdata is compatible only with a few ECUs and they are all obd1. for obd0 take a look at turbo edit... for obd2 you better put a conversion harness to go back to obd1 or buy $$ hondata. i've been using uberdata for a couple of years now, its very stable, but support is horrible. uberdata can be used to log, but that is not one of its main features in my opinion. It is mainly used to remap the fuel maps and ignition maps. There are a total of 4 maps for vtec motors and 2 maps for nonvtec motors. Uberdata allows you to turbo the car which is another one of its key features. I havnt upgraded my uberdata version in atleast a year. So there are probably many other features on the new version. Some features are 1. Full throttle launch (build boost in netrual 2. Full throttle shift 3. boost cut to install ubderdata is very simiple. 1. remove and socket the ECU (remeber only certian ecus are compatible all are obd1) 2. open uberdata software 3. set fuel and ignition maps 4. write to eeprom 5. install in the car 6. tune the car and goto step 2 until you are statisfied Nick
