MaxxECU Questions and Support/Purchase: Post them here

You must have only one tooth 90* or so btdc on your distributor to denote engine phase to the ECU. You may message me for remote tuning needs, then you can go back to whomever is finishing up the car.

Thank you. How can I get you in contact with my tuner? He has a few questions for you. Does email work?
 
Hi guys, I have a Maxxecu Street on my 940. Can I install an E-Throttle without buying a Maxxecu Race? With a CAN BUS module like the CANchecked MCE18 - Multifunction CAN Bus Extension? Or another solution?

It would be a shame if it's not possible, but I wouldn't upgrade to a Maxxecu Race just for that.

Thanks

Should be possible: https://www.maxxecu.com/webhelp/can-modules_e-throttle.html
Bad part, they don't make these modules anymore.

I have Ecumaster H-bridge driver with E throttle. But not with Maxx. (Labview and Peak is the combo)
 
Kinda weird without current monitoring, but it could possibly work? I have never tried it with an H-Bridge driver. I can't say yes or no.
 
Hi all! I found the forum while trying to find some answers regarding my maxxecu mini setting. I've installed a mini in a V-Twin engine with individual intakes and completely different cylinder settings. I'd like to tune the fueling individually, however as I understand the common way is to tune one cylinder and then the offsets for the other. I find this counterproductive and I would like to have completely different maps. So I'm trying to set the ecu to work with Dual VE tables, but whatever I do I can't seem to find a way to configure what table does what. Does anyone have any experience doing that? IIRC Speeduino or Rusefi had a setting to choose in what bank the injectors belong, is there any similar setting hidden somethere?

Thank you!!
 
If you want to tune individual banks I think you need something more professional. EpicEFI might have what you are looking for at a budget


Rusefi on steroids.

Interesting! That's - another - efi to check... I decided to use MaxxECU after having problems with the triggering part of ecumaster for my particular engine. Thing is the maxx is supposed to be able to control/tune individual banks ..

(gonna check the epicefi now)
 
Maxxecu is overpriced garbage thats meant to be plug and play. If you don't know what you're doing and want a safe bet Maxxecu is the way to go.

EpicEFI is meant for those who want every single function possible and more.

I use Speeduino but I do not like it. Too raw in its functions.

In MTune, Fuel->Fuel General->Fueling Calcualtion, you can pick Dual VE. That will set up 2 VE tables (and 2 long term trim tables if you use LTT). But to make those useful, I believe you'd need 2 oxygen sensors, ideally wideband. Then, you can fill your VE tables based on target vs measured lambda, for each table/sensor pair.

Indeed, and I've also configured 2 widebands. However only one of the VE tables seems to be working. i.e. I'm changing the values and measuring the output, but VE Table 1 is useless .. even with zeroed out cells it has no effect whatsoever. I tried many variations, configured the injectors manually, tried enabling/disabling almost everything etc. I just can't find where (if) there's the option to set which VE table effects which cylinder.
 
Hmmm. I assume you have Configuration -> Engine Settings -> cylinder count = 2.
Then If you go to inputs-> lambda sensor-> lambda sensors and select 2, you should then see just below that "cylinder sensor assignment" and you can assign which sensor to which cylinder.

Done that too, I'm using alpha-n and I've also noticed that the manual says that autotuning won't work on the second table. However the problem is that I just cant figure out where to set: VE Table 1 -> Cylinder 1, VE Table 2 -> Cylinder 2. Or maybe: VE Table 1 -> Bank 1, VE Table 2 -> Bank 2, and Cylinder 1 -> Bank 1, Cylinder 2 -> Bank 2. Or something like that.

From the manual:
"DUAL VE - One VE table per bank. Requires dual lambda sensors, mainly for odd-fire engines where the cylinders have different fueling due to intake harmonics.
Note: Autotune functions will only adjust the first bank, VE Bank 2 table will NOT be autotuned."
 
I believe VE table 1 is for sensor bank 1, VE table 2 is for bank 2. I don't think those can be otherwise assigned by the user. Not sure though.

Let's agree to that! (That's what I think too..) However, which cylinder belongs to which bank? Even in a V8 engine, not all mfgs enumerate their cylinders the same way, however the numbering goes alternately from bank to bank and so cylinder 1 is on one bank, cyl.2 on the other. Yet my VE Table 1 does nothing whatsoever, while changing the VE's of Table 2 affect both cylinders.. I guess I'll have to create a single VE Table and use individual trimming for each cylinder - which I find counterintuitive as it just adds another variable to the whole fueling calculation.
 
I'm missing something.

So the Mini has no internal WB controller, so you have 2 CAN WB sensors and 2 controllers or a dual controller?

I'm using 2 sensors (internal controller plus an external CAN controller), and 2 VE tables. It's working as it should (and it's weird but sometimes "autotune" adjust VE2 as it should, and sometimes I have to do VE2 update manually like the help explains.)

Firing order is defined under "Engine Settings"
Dual VE (per bank) is defined under "Fuel General"
Cylinder assignments to the 2 sensors are made under "Lambda Sensor", and I think essentiallhy this is where "banks" are assigned. You assign lambda sensor A to a controller, and lambda sensor B to the other controller. Then below that, you would have cyl 1 assigned to sensor "a" and cyl 2 assigned to sensor "b", for example.
