I strongly recommend tuning manually after doing the auto tuning because autotuning only gets you into the ballpark. Unlike contemporary factory ECUs there is not enough memory in the ECU to collect historical data and continuously refine the tuning as you drive. Manual tuning can be a long and tedious process but it's worth the results. Start by focusing on the zones that you encounter most often, then do the remaining zones at your convenience. The most important aspect of manual tuning is that you acquire log data for the zones to be adjusted in a stable state, ie. close to the zone center in both RPM and MAP, minimal (preferably no) acceleration or deceleration and no more than 2-3 kPa change in MAP for two seconds prior to the point in the log data where you look at the A/F to see if it's too rich or too lean. For the higher and lower zones this will require finding a long hill with a suitable slope (up or down as appropriate) and selecting the best gear. ----- Original Message ----- From: Stephen Rigley To: MiataPower Sent: Wednesday, September 30, 2009 9:08 AM Subject: Re: Link tuning
Got a copy (thanks Richard!). Loaded (manually.. ugh) the latest defaults and did a power run (attached) .. Now.. *cracks knuckles* where to start? ;-) Steve On Sun, Sep 27, 2009 at 8:19 PM, Stephen Rigley <[email protected]> wrote: Hi, Anyone still have a copy of or a link to, the link data logger for the ipaq?
