You are correct. The MAP values are in KPA, TPS are in % throttle.

Lyle...just curious...did your logs look ANYTHING like this at idle?!? Think the cams are REALLY giving the MAP fits at idle. Still working on a few possible solutions. The good news is that it looks like we have vacuum...just VERY erratic vacuum. The A/F ratio is also all over the place, although it is consistently decent and the bike doesn't sputter at all. Will get some good tuning logs put up tomorrow. LM1 was not cooperating with me today.
Note: Still reading MAP as "voltage only" because I haven't configured the channel just yet...
Otherwise, the 916 with 109 injectors is flying!!! Got it to 85 today in well below 500'!!!

First run. VDI and m109R injectors in 916EFI Brute, with muzzy pro and major intake mods. 100 ft above sea level. 20mph rolling start with a slow roll into the throttle(obvious reasons without a wheely bar). We are WAY outside the "test range" so to speak on this setup, so had no real idea what to expect.
This is with ZERO smoothing applied to afr. Congrats to Lyle. This is the FLATTEST a/f curve I've ever seen in an "initial" map in my LM1! Yeah, it is a bit lean, but the "flatness" speaks the greatest volume of the stock tune of the VDI. There was no way it was going to be perfect for our setup out of the box, but this gives us a VERY good base to work with!
Will report back when I get it dialed! Already made some major adjustments to the fuel maps!

Engie,
Part of the issue feeding the MAP into the LM1 meter is the MAP reading on a single cylinder (sensor is just on the front cylinder) isn't constant. It's usually a flat line close to barometric, that blips down on the intake stroke. So you really need to sample the MAP at BTC of the intake stroke.
The cams could be causing MAP issues though. Thats part of the reason for the switch to TPS at higher loads. We were getting a lot of intake harmonics from the second cylinder barking up and back down into the first cylinder. This might not have been an issue if they weren't both breathing under the same filter. But, we couldn't expect people to replace the filter too, so we did "Plan B" which is similar to the OEM operation.

So is it even possible to accurately log MAP on the LM1?
This is what I did to "overcome" the MAP inconsistencies. I know this method is not even remotely close to perfect, as shown by the STD deviaton here, but with enough compiled data should provide something close enough to allow adjustment. Gonna test and see if it works out. This is with maximum smoothing applied to MAP. I assume that the MAP portion of the table runs exactly like the TPS portion...with 20 MAP being approximately idle. Can I make this assumption?

I don't think you can use the LM1 to acturately map the MAP. Idle is 20-25kpa, so you are correct there.
The problem with the LM1 and the MAP is it doesn't sample quick enough. I talked to Innovate and it they are limited on how fast it can sample. If it did, you would be able to see that flat line, with a dip down, and you could pick the minimum dip (that's what the ECU does).

Typically, the firmware is stable (now). Other than a minor tweak when we added in the Teryx support, the firmware typically doesn't need changing.

Got my VDI put on today. I only got to ride it around the yard for a few mins. I noticed quite a difference right off the bat. Didnt want to get the bike too hot, I had to remove the exhaust and install my water temp gauge plus a few other goodies. My Muzzy should be here on Tuesday then I'll load the correct map and let 'er rip! To anyone who's added a map on, is it pretty straight forward? I've never messed with a programmer before. Gonna use my cousins laptop to do it. Thanks for the fast shipping Lyle! Ordered on Saturday, they shipped Monday, got it here in Michigan on Thursday! Muzzy is coming from Oregon and taking two extra days over the VDI from Canada. I dont really understand that.

If his CDI has the removable harness, you just need to buy a new harness, and download the firmware/maps to make it go. If he's got one of the GEN1 units (one of the first ones we made), then the wires go straight through the metal plate (through a grey grommet), and it cannot be changed over.

Got my VDI going and uploaded the 10% fuel map for my Muzzy system. The install went great. No problem with the software and map loading. This is my first ECU install and it went very smooth. I had a problem with cold starting, turns out I messed up my valve job. So of you that read this post prior to this edit, all is well with the VDI, just my valves were wrong. Thanks Lyle!

Have a question on this ecu. It says you can change timing w/ this ecu but isn't there a sep. ecu for timing? If there is it's diff. for a 08 to a 09. I was going to get the VDI but couldn't wait so I got the power commander for a 08 cause I couldn't wait on them either :)

There is only one ECU in all these machines. The ECU controls all the operation + timing and fuel. Our unit replaces the factory unit to run your bike.
On other machines (Rhino for example), other companies put on a piggy back unit that changes the timing from the factory unit, but you can't adjust the fuel without another add on piggy back unit (so you add 2 extra units to the factory unit, that ours does all together, by itself).

We've updated our website so if you order an ECU, you can now select the octane, tire size, injector, pipe etc. on the ECU when you order it.
It will get preloaded with your specs when we package the unit. If you're not quite sure about something you can indicate your concerns in the "comments" section of the checkout.
This should help out you guys that want to run the unit, but are a little concerned about programming it.
In addition, we've loaded a new firmware and map for the BF/teryx. It riches up the WOT maps for better power, as well as addresses some starting issues and a miss at 30MPH.

Yes, you bet. If you had been running the +5% map, that is already merged into the fuel map of the 1.4a, so you can just run the regular non-pipe map.
