Thumbs up PCV custom maps (autotune) Power Commander

Let's use this thread as a repository to attach custom PCV maps from using autotune for the RC51. The Power Commander website seems to have only older maps, no A/F targets, etc., which the Power Commander V can now do with the Autotune module.

There are two ways to attach the PCV pvm extension file.

The first way is to zip the file. Use a zip program or for modern PC OS systems, right click the file, select send to, select compressed (zipped) folder. Attach the zipped folder in your response here using manage attachments under additional options, after selecting post reply.

If you can't zip a file because of an old OS, this is another way to attach it. Rename the file from zzz.pvm to zzz.pdf. Then this forum will allow that attachment. And if downloading a PCV pdf file in this thread, do the opposite. Rename the downloaded file from zzz.pdf to zzz.pvm If attaching a file this way doesn't work for you, google "how to view file extension" for your operating system.

I will attach my custom map when in this post as soon I get it built up. In the mean time if a few get posted, I may use it as a base map from which to build my custom autotune map.

Also please include a description of the modifications, bike year, sp1 or sp2, location (state or country), and notes (e.g., performance map, fuel economy map, target A/F of X) anything notably associated with the map.

Important
There are issues with all dynojet maps currently available and listed on their website for the RC51 when used in conjunction with the gear mapping option for the PCV. And likely also with all the custom maps people are sharing. I spoke with Dynojet about some observed issues and they were able to identify the problem, a bug in the map files for all existing RC51 dynojet maps. They fixed the bug with a new map file and emailed me a zeroed base map with the bug fixes. If you want to use existing map tables, the fuel and AFR values can be populated in this fixed map by copying and pasting from whatever map you want to use.

I highly recommend using this map for all PCV map building for the RC51. It will provide for future intercompatibility with all PCV tuning options even if one chooses the single base fuel map option. It can be found attached.

You can see the discussion around this in my PCV autotune install guide here. https://www.rc51forums.com/forums/sho...137#post660137

Kwtoxman,

Having an issue with opening your base map that was attached in the above thread. When I download it the PCV software doesn't recognize it and nothing else will open it Sorry to bother you on this. Also I know you run ladybirds. You wouldn't have a map laying around for just the flapper mod and ladybird slipons would you.

No problem.

The file needs to be unzipped after downloading.

I haven't begun building a map yet. When I do and consider it decent I'll post it here. I'm a low miler so it could take the summer.

I got it now. I thought it unzipped automatically. Done.

I got a map from Madbuyer but his has the pair removal as well as the flapper removed. I just plugged the flapper valve hose an left the pair on (so far). He had ladybird GP pipes but it was dyno tuned so I figure it's a good place to start.

I am really liking the PCV and AT on the RC51 so far, though I haven't ridden it enough to provide full feedback.

In reviewing the data I also see the map needs to be built up more as a lot of cells have no significant trim data yet. But so far the changes I see in the trim tables are consistent. And it is pulling back some heavy fueling on the aftermarket map I'm using.

I'm just not a high miler. When I get a better representative full map, I'll update.

Hey kwtoxman (and James_03_rc) thanks for all the effort you have gone to in this thread and elsewhere. I've been using the AT plus the POD300 to build a map for my '03 with the Hord motor (cylinder advance only). The results have been OK so far but without a dyno it is difficult if not impossible to determine ideal A/F - I've erred on the side of caution at 12:8 for 80% and 100% throttle, leaned off to 13:2 in the cruise area. I've only used the AT at the track, doing a few laps then coming back in uploading the map and viewing the trim tables - easy enough to maintain constant temps so the timing option (I set it at 2 mins) was fine for switching on the AT. After speaking to JD I inputted some figures directly in the fuel tables to cure snatchy throttle at low revs (rolling on out of corners), it's a lot smoother in this respect now but a long ride yesterday revealed some lean surging at low throttle, high gear cruise around 4K - 6K RPM. I think using a switch to engage/disengage the AT would help diagnose this. I've attached the map I have as a work in progress.

Here's some spreadsheets which show where the AT was active - the shaded areas indicate no change over the base map I started with but as I said before I altered fuelling in the 2% and 5% throttle low RPM area directly in the fuel tables.

One thing I miss about the old PC3 software is the map compare function, sadly lacking in the PCV.
