Microsquirt V3 on Yamaha Banshee project - R6 Map sensor ?'s

[Whitbread]

Hello Gents, I'm in the middle of wiring up my banshee using 04 R6 throttle bodies and ls coils. I've read everything I can find at least twice and have a good grasp on everything so far. I'm trying to look ahead a few nights when I start talking to this with the laptop for the first time and start calibrating sensors. CTS and IAT are gm ones so easy there, R6 tps is easy to cal, but I'm somewhat stuck at the map sensor. Does anyone have the calibration curve for an 04 R6 MAP by chance? It's nice and tiny and came with my $9.00 fleabay set of tb's, so I'd prefer not to buy a giant gm one and stuff it somewhere.

Thanks a bunch! I'll put up some pics of the project later tonight.

Hi,
I know the R6 is a Mitsubishi part, and there is a possibility the service manual for the R6 gives a calibration curve diagram, like my GTS1000 ones do, but I haven't been able to check. I doubt the Nippon Denso curve I have is any good, so I'd suggest you test it...

Hook the up to 5V & ground, and measure the signal voltage using a multimeter and silicon tubing a tee piece connected to a vacuum gauge & a medical type syringe.

Start at nothing (open) or 1 Atmosphere, connect the hose to the sensor, and it'll be around 4.65-5V. If it isn't, it'll be greater than 100kPa to compensate for a ram effect possibly, so it'll read a lower voltage.
Then suck the air out, and record the pressure & volt readings.
They are usually a straight line plot, V vs kPa (or as near as dammit).

I know it's work, but I got a dinky Denso one too with my Aprilia TBs, and would have done the above, if I didn't get lucky in my searches.

I have the 03-04 R6 manual in my library, and no, it does not have a calibration curve.

That's basically what I ended up doing with a mityvac. I fiddled around with the numbers in TS until it read correct numbers for -29.9"hg and atmospheric pressure. Math says this means it's a 2.5bar sensor. Glad to know I'm covered if I ever decide to boost it!

I have the 03-04 R6 manual in my library, and no, it does not have a calibration curve.

Yeah, I found a copy on the net, only thing it said was around 3.6V at atmospheric pressure.

For reference of anyone else, the specs I came up with are -100kpa = 0v and 160kpa = 5v. This gives correct reading of 101.5kpa with the sensor out in the open and -98kpa with mityvac sucked down to 29".


Here's some pics, took about 12 hours yesterday and today of wiring work. Need to tape and loom it up now.


Wohoo! LC-1 wasn't powered up so that's why 02 reading is off.
