Intended to get something like a type 2 board, but no s/w. Also will look into PC BIOS backup/switch boards & software. These ECU eprom sockets are obsolete, and I expect there is junk out there for nothin' Plenty of time.... It's a slug & I'm old, and patient.....

Try those addrs's on the wknd. RB30 in a 32 looks fun....

Yes, this is the way my old version works. I can't imagine that that would change, but U never know.... Shame we have to pay for the new one (hence all the questions), but it's not much. Now, let's pop that rom out, solder in the piggyback, wire it up and were away.... No more soot on the boot......

Cheers pete. That nails the TP value. Do the new versions actually read the maps in from ROM & display them? If so, then it's what I'm after.

Further to that, it just occurred to me that the real time TP address might also be a memory mapped I/O register that the CPU reads to get the TP. Either way, it gives access to the TP for this particular datascan option.

Thanks for rply, Take a look at inhibit_harvest_url_ttp://202.43.224.130/ with the "inhibit_harvest_url_" bit replaced by "h" of course. point 10. 10. Map trace A real time trace of a position on the map. This function is only available for z32 300zx cars at the moment. If the real time TP value address is known the function can be set up to work on any Consult I Nissan car. The TP address is the spot in RAM in the ECU where the CPU stashes the TP (throttle pos). In datasacn, you can tell the map trace function this address. Then the map trace function can get its grubbies on the TP. Next U watch the track of the trottle/rpm curve pass over the timing and fuel map as you wind the car up. When you get ot a place you dont like the feel of, or it leans out or pings, you can tweak the map there That's assuming you know how to down & upload the maps. That leads to my second question. Does anone know how to give datascan more (read my custom) maps? That way, I could read my values off the display instead of having to look them up in a seperate app.

Hi, In attempting to track a trajectory on a map in Nissan datascan's "Map Trace" function, the TPS gets stuck on the minimum value. I recall that if U know the address of the TPS value, U can get this to work on any RB, SR, etc. My application is an RB20DET, stock CPU. Anyone know where the value is hiding? Also, any hints on how to extend the selection of available maps would be great.
