Custom Plug and play Megasquirt systems

[rs4pro3]

I built one of these for my car and have a good bit of interest to start making them for others. It's a 95% plug and play setup for any 325i. Additional items needed are a variable TPS, Intake air temp sensor, and some minor wiring to the main relay, and possibly a wideband o2 sensor if you plan to tune yourself. Features include a v3.0 main board with spark control all housed inside a stock 325i ecu. You can simply unplug your stock ecu, and plug the new megasquirt box right in. Here are some pictures of the setup




Ok here is the current pricing

Eta setups(includes ecu and adapter cable for 325i VR sensor, you'll need the 325i VR sensor, pulley and bracket)
ms1-$600
ms2-$700

325i setups
ms1-$550
ms2-$650

All setups also have a $40 extra ecu core charge if you don't supply your old ecu.

Add on options include(these prices only good with purchase of a plug and play unit)
external USB-serial adapter-$20
variable TPS-$40(plus $15 core charge)
air intake sensor with wiring pigtail-$40
Innovate lc-1 wideband-$200

Any special discounts for cheap ass friends?

So what would be necessary to convert this board to MS&S? As in distributorless, not just spark control.

Does anyone know if M42 coil packs could be used? Seems like they are 2 sets of 2, so adding a 3rd pair should be easy.

Can you do the video display output of this on an LCD?

Thanks,
Luke

you could change it to run waste spark pretty easily, a good number of people have been using gm coils with good results, all you need are 2 additional coil drivers, the coils and spark plug wires. Then you can ditch the stock cap and rotor.

Ya you can use megaview to display info easily somewhere on the dash

If I ever build a new chassis, I will be ordering one from you just to ensure that I have a clean product.

Where were you over a year ago when I had to do this all on my own... Only downside I see is no use of a megastim..

that thing is sexy

Why would you want M42 coilpacks, they're huge!

Get E39 Coilpacks...

how bout a system for m42s?

The ones I saw were not coil-on-plug, but looked like 2 groups of 2, with wires. I wanna make a coilpack on my firewall, just for looks.

Thanks!

you can still use the megastim board. I utilized a different DB37 plug so you can unplug the ecu plug and plug in the stim board. Or reuse the board for a different application. I did not want to directly solder the wires to the board so I found a verticle versus horizontal db37 that would still fit in the case.

I could possibly do one, not sure if there is not enough room inside the m42 ecu case for the megasquirt board. If you can get me some dimensions of the case I can check if it would fit.

Hokay, I gots more questionz.

1. Can you lose the AFM? What woudl you want me to do instead, use speeed density or MAF or what?

2. Is a different TPS required? Wasn't it the E36 TPS that bolts in?

3. How far can you take this one? As in can you change the MAP sensor adn be turbo-ready? Can you control a wastegate with this?

4. Is it possible to add a knock sensor on this? I understand that an M20 is too noisy to use one, but what about an M50?

5. I cannot seem to find a picture of the LCD. Do you have one?

6. If I were to have a car-puter, would it be able to display tuning data (RPM, A/F R, timing, whaddevah) adn show it on a monitor? Can you make changes while driving?

Thanks!

for the M50 ? possible ?

1. Ya no AFM, or MAF needed. Megasquirt uses MAP pressure instead. All you need is an air intake sensor somewhere in the intake tract, either the oem bosch one or an GM sensor. So basically no restriction from the airfilter to the throttle body
2. Yes you have to have some sort of variable TPS, the e34 auto m20 one bolts right in and just needs wiring. Or the e36 one can be used and you can make an adapter bracket
3. You can go as far as you want(as long as it all fits inside the box). The board has a good size prototype area where you could set up boost control, fan control, vanos control etc...
4. Yes a knock sensor can be easily added( a knock controller is needed, I personally really like the viatrack unit)
5.
6. Ya you could set up a car-puter My friend has one in his car and can view all the engine functions real time and adjust any parameter. He mounted a 7 inch touchscreen panel down in the center consul.




As for the M50 again it depends on space, I have a non-vanos ecu sitting here and it's too small to fit the megasquirt board in and still conceal all the wiring. For some of the smaller ecu's I can make adapter harnesses to adapt the megasquirt db37 plug to the stock engine harness.
