i found that info EXTREMELY helpful. After talking with Paul, it seems that I haven't scrathed the surface of what this ECU is capable of...
Aaron, I read something about multi-spark control yawpower.com, do I NEED a unit such as a MSD 6A to ignite spark, or can the M2R handle after market coils?

i had a MOTEC PRO take a look at my map, and apperently, we weren't anywhere near full potential on this unit.
Also, when I purchased the M2R, I opt'ed out of the Lambda option. Mostly becasue they gave me some 'free' trail time to test it out, and I hadn't experienced the Lambda option before.
After playing with that option a bit, i realize how valuable it is... You literally dont have to do ****... after you've got a base map.
You basically, input the desired AFR at different points on the map (say at boost, idle, and crusing). The M2R will smooth out the map, and keep you car tuned based on AFR. If the AFR starys from what you want, you literally hit one button. Doesn't get much easier than that.
I am now trying to understand the clsoed loop tuning option. I hear that is the way to keep these cars tuned and really dial them in.

I loaded the map I got from Yawpower, and IMMEDEATLY, the car started up better, and the throttle response was MUCH better. The car is running pretty rich all over, but keep in mind, Paul has never seen my car, just spent some time on a map and sent it over via email.
I was able to tune the idle myself and get that dialed in.
I am finally begining to understand how to tune.
There are some really cool options I am begining to consider with this ECU. Since I am already using methanol, I think the next little project will be to get the motec to govern that. That way, it will spray on a curve, instead of just on or off.

Dude, no doubt. Also, another bit of mis-informaton about the motec: you dont have to purchase the lambda option in order to activate lambda tuning!!!
Basically, lambda option allows you to plug an o2 sensor RIGHT INTO the ecu. If you have a wideband, such as AEM, you dont need the lambda option.
Instead, you only need to purchase the advanced tuning. This option enables LOTS of cool features (lambda tuning, traction control).
Keep in mind, some motec dealers will include all of the extra options with purchse of the ecu, so you'll have the full package.

So after Yawpower took a look at my map, and sent it back, i noticed an improvement in the drive-ablitly, instantly, but I also noticed a couple errors in the error log. I was getting PEAK errors on the primaries.
After talking with Paul, there was some concearn about the impedence of my injectors, so I grabbed a multi-meter and checked it out.
Turns out my primaries where High Imp, while the secondaries where low. The M2R allows you to pick your impedence, but all injectors must be the same.
I was able to find some low-imp primaries locally. (thanks Digi7ech)
So I will hopefully have those over to Paul this week and back in the car by weeks-end.

I went to Paul's shop last night to get my injectors back. He ultra-sonic cleaned them and then gathered the dead-band timing info.
While I was over there, I purchased the advanced tuning options. So I'll get the telemetry, lambda tuning, data logging, closed loop tuning, and all the good stuff!
So this evening, I should have my car running again. (it's been 3 LONG weeks). But she'll be getting much better gas milage and the drivablity should really improve.
I've made plans to go tune the car on Sunday, and we should be able to figure out how to connect the methanol injector to the Motec shortly.

Got the injectors in, everything looks fine under the hood. Now that the injectors are clean, the car is running pretty rich. It's kinda hard to drive at this point and I could go through the maps and lean it out but...
I've got the lambda tuning and wanted to give that a try. After setting it all up in the software, I noticed that the AEM gauge and the laptop displayed different values for lambda.
After going through some trouble shooting, I realized that the ground wire for the gauge HAS to go to pin 32 on the Motec. And mine isn't. It was like midnight when I got to this point, so it'll have to wait till tonight.

Good to hear its coming along...one general question on the unit though.
After reading the features on MoTeC's site it seems the M2R has only one aux. output. Is this true? If so, what features does the unit control that aren't counted as "auxilary".
For example: You could use the spare output to control say, an e-fan. But is there another output thats already dedicated to that function? Or is there *literally* one output for things like e-fans, wastegate control, aux injection, etc. ............to put it another way, is there other "extra" outputs dedicated to an e-fan, or an RPM dependant switch etc. or is there only one channel for these other items?
Any help is appreciated.

actually, there are two auxillaries. Not sure where you read that there is just one...?
The m2r (m4) doesnt have separate channels dedicated to specific aux devices. *Such as e-fan, fuel pump, aux injection... because none of these things are 'necessary'.
But with the M400 (M800) these things do have dedicated inputs if I am not mistaken.
You can actaully add whatever you want to the auxillaries. I mean, the possibilites are endless. You can hook up a **** to control boost, aux inj, **** you could even hook up a heart rate monitor to it that will slow the car if you start to have a panic attack!
But to give you a clear answer as I understand it is, there are two auxilliares set aside for not essensials.

Thanks for clearing that up Nick. There are a total of 4 aux outs on an M4, however on a rotary, you end up using 2 of them to run ignition and are only left with 2 to control fuel pump, fan, etc. There is a way around this as you can purchase an ignition expander box to control up to 8 ign outs from the single dedicated ignition out on the M4 and are then left with all 4 aux outs to use as you desire.
The M400/600/800 all have 8 proprietary aux outputs separate from ignition, so you can run a plethora of functions all with the immense control that version 3 allows.
I need to remember the heart rate monitor compensation, that's a good idea!!

Ahh I see, thanks for clearing that up.
My reasoning for thinking you're left with one output was after some reading on their site and me considering the use of one of the two remaining channels (after two are occupied by ignition for the rotary) for a fuel pump since I considered that necessary to be controlled by the ECU. SHould've mentioned that, and I guess it really doesn't need to be.
2a+RoN Thanks for the info on the expander box - that'd be something I'd be after along with this ECU.....

I have my fuel pump wired to a cut-off switch as a security feature. This may be an obvious question but, What are the benifits of having the fuel pump controlled to the ECU?

Well in the case that say a fire starts in the engine bay or get into an accident and turn the key off but leave the fuel pump running, it could be bad news..
I usually pull out my motec so nobody can jack my ride

so we tried to get the lambda tuning to funtion properly. there seems to be an issue between the motec and the AEM gauge. I've tried all the different output modes on the gauge, but none match what the motec is getting. It seems that the AEM gauge is reading AFR properly, but not inperpolating into the motec software...
The car is running a little better, but I have yet to experience the glory of lambda tuning.
Paul is going to contact motec to see if there is a change in the lambda scale for the M2R.

the answer is, Don't use the AEM lambda gauge.
I am going to have to use a potentiometer to control the voltage from the gauge, to the motec.
The gauge comes with 5 modes, but none funtion in the proper scale that the ecu is looking for.
It seems that the AEM gauge cannot be programmed to output the scale I need, thus the need for the potentiometer.
I would suggest for any other motec users to go for an innovative wideband, or any model which allows you set the voltage scale.

So Paul at YawPower.com got the AEM gauge dialed in. It seems like the manual that came with it is wrong about the modes... He did some test with one of the programmers over at Motec USA and found the exact scale that we need to use. So we are finally dialed in there.
It sucks because I really like ALL the products I see from AEM, but with the manual being wrong and the gauge not outputting how I expected, I may look else where next time I need something. Or at least do much more intense research.
On a happy note, Lambda tuning is damn smooth. I just hit the 'Q' key and ECU adjusts the AFR to what I want. I dig it.
Also for the first time I enabled data logging. I am still new to this all, but motec also offers a free download of a software called Inturpretter. I can take my logs and fine tune them in this software. It shows me what I want (previous inputs) and shows me how my car is actually running. From there, I can fix it without being in the car or having it running. Still learning but it seems extremely useful.

unfortunetly, the same isn't true for AEM.
After all the issues with the AEM, and finally matching the scale, it still is getting a different reading after a lambda of .96. It matches in the richer readings, but not once the motor leans out a little.
The owner of Turblown met an AEM guy in Vegas last week, so hopefully we can get him to help us figure out why his product giving us so many problems.
Overall, tho, the tuning is going well. The car is getting close to dialed in at cruising, hopefully boost isn't too far away.
