The datalogger has to be redesigned, but yes, it will work. There is a new serial interrupt routine written by a "l3st4rd" at PGMFI that lets you poll all memory locations in the 8051. Sooooo in less techno-geek language, we'll be able to do whatever we want with the datalogging, including change values while we're driving (RTP)!!

Thanks PGMFI.. we lub ewe!

where do I plug in to get the information from my ecu to my computer?

TurboEF9

You need a TTL -> RS232 converter and a serial cable.

Here are pics of my install (http://www.driftkids.com/pics/jason/ecu)

thanks.

why do the values for the stock pr3 only go to 7400? is there a way to make them go higher?

TurboEF9

They do go higher, I just never got around to changing the grid, sorry.

I just used the same tabel creation routine for the second set of tables as I did the first only changing the values.. that should be fixed in 2.0..

Honda16hb

in the future could the rpm points be user entered? is there something within the pm6 that prevents it from reving past 7.4?

TurboEF9

They can't be user entered.

As far as being adjustable, that probably won't happen either.

For a bit of good news, I think Blundar is working on something..

Honda16hb

so the lack of adjustability is for idiot protection?

TurboEF9

No it's a limitation in the math used in the interpolation routine.

PR3/PW0 use a different' routine to figure out which tables it's going to use, however, it's still the 15x17.

Due to 8-bit math limitation of the 8051 microcontroller (Highest calculating number being 0xFF or 255 in dec, which happends to be 15x17, make sense?) , a different routine would have to be written to either A) incorporate a 16-bit math routine, or use Dave's loopup table routine for RPM rather than boost.. and like I said, I think he's working on that.

Honda16hb

ya, I get that so far. so with dave's rpm loopup would boost capability be lost? and with this loopup could the pm6 rev past 7.4?
