Hi! I'd like to know if it's possible to suit o5e in a vitara 1.6, and what timing wheels are accepted.

In theory, sure.

I say in theory because o5e has never actually run anything :shock:

it should work...but it hasn't been tested. I'll get back to it once my engine is running.

Right now 05e require a missing tooth type crank wheel with 1-3 missing teeth. Ideally you will also have a single tooth cam trigger. There is some newer eTPU code that gives more cam options but I haven't messed with it yet.

thanks for your answer.I will wait your news :D Have you a link for newer etpu code?I'd like to take a look of it. Sorry for my bad english, it's not my language.

You can check out Freescale's eTPU function selector here.

Tanks. I'd like to do other 2 questions :
etpu Fuel Function support sequential inj?which cam wheels are supported , I've serched in freescale Application notes, but I was not be able to find answers to my questions.

The old code only wanted a 1 tooth cam wheel, but any wheel that had a tooth with no tooth 180 degrees away would work with proper windowing set-up.

The new code is a little confusing, I haven't played with it yet and it's not installed in o5e yet...but it looks like pretty much any cam wheel should work. The new code will also accept missing and added teeth on the crank...so more oem type options should work.

So if i put a 36-1 wheel on crankshatf and a 1 on tooth on camshaft, i can try to use old etpu code right? can i also do sequential injection?

Yes and yes along with COP ignition.

Are you thinking about giving it a go?

Very cool....you could have SOO used you a year or 2 ago:)

What are you going to do about drivers? MS3X or????

We'll need to figure out which code for you to try....I almost don't even remember where this was. My plan was to get my d*** engine done then get back to this and I've purged my brain.

Does your project have a timeline of any kind so I know when you'll be needing help figuring out what the heck we were thinking with some items? :)

yes, i've started from trk schematic, i add FT232 for usb connection, max9926 for crank and cam("copy" from freeems), 4 igbt for inj(self-protected), 4 igbt(450v clamped) for direct coil, a few of mos for idle valve, fuel pump ecc and some analog channel for tps, map o2 probe ecc; i may use some driver like IXDI404-6 for drive igbt and protect mcu; now i'm designing power supply stage. I have some doubts on max circuit, and some pin of mpc563m, but i hope to solve when i'll recive components that i've ordered. I'd like to try with 2 layer pcb, but i heard that can be affected by noise and 4 layer may be a better choice. If i finish i think i'll test first my project on another car because i need to use vitara for now.

That's a BIG project, good luck with it!

Have you got another car to put it on? That's been my problem, I won't try it on my daily driver because it has to drive every day and my toy isn't running :(

I know but i've time. I haven't another car but i've thinking 2 solution:
a friend would be a tester with his old car, or I can find another suzuki vitara motor, an try to start it without the car, and the if it work move ecu on the car. certainly I will need help for complete my project :)

If you post questions, I'm sure one of us will answer, and give the best response we can give based on our experience.

As I mentioned in our PM exchange, I think starting with the TRK board and adding on little boards so you can develop one aspect of the system at a time, is a good starting point- most functions can be developed on a 5x5cm board... give or take... so the cost is rather small. Only after you have working boards for everything, my opinion again, should you spin off a full single board incorporating what you have.

Consider the various aspects such as voltage level translation, signal isolation and buffering and such, and you should be fine.

my design is only a draft; i'm waiting for TRK board and components now . next, like you said, i think i'll do some test with trk so only if it work i'll realize a "all in one" pcb. ;)

You might want to look at the schematic for the Freescale Monaco/MSQorivva which were posted by Mark on the old forum. A few more rounds of massaging and it could have been a very nice board at a reasonable cost. You might also want to look at the S12XE. Don't see why the o5e code couldn't be adapted and it's a better fit for a four or six cyl. If it can be proven that it can actually run an engine, you could even port rusEFI to the S12XE or TMS570LS20216.

I've seen MSQorivva schematic, but I've some question. First of all:
msq use mc33810A to drive ignition coli and injectors IGBT; can i drive igbt with IXDI404 or similar, using etpu pin, without MC33810 IC(like Megasquirt)?

Realistically, you can do whatever you want... if you have the proper supporting circuitry.

IXDI404 are meant to be MOSFET / IGBT pre-drivers, best I can tell.

33810 can directly drive (i.e. provide current sink / ground path switching) for up to 4 high impedance injectors, and drive 4 N-channel Mosfet or IGBT's for ignition coils and provide current monitoring / feedback for those.

It can also provide feedback to the MCU over SSI/SPI and trigger outputs via either SSI/SPI or parallel type interfacing... something discrete drivers won't support easily.

i've read now datasheet of this ic, it's very interesting thanks for your advice! i'd like to use another igbt, so i think resistor on the ignition output pin should be changed, but i've not found how in datasheet. do you have some info?

You might take a look at the evaluation kit for the 33810 chip here. The user guide and schematic for it are here.

It uses IRGS14C40L IGBT's to directly drive four external, inductive-type ignition coils. These are logic level gate driven IGBT's so theoretically, the 33810 circuit could be adapted to fire GM/Delphi LS type coils.

The resistors shown on the IGBT part of the schematic are for voltage/current monitoring / fault detection and aren't strictly required if your application doesn't need that.

I think I'll study better this IC; voltage/current monitoring / fault detection are interesting features. Thanks again! :D

In MSQ schematich i found barometric_P_i and Mainfold_press_i what's the difference? i think Mainfold_press_i is MAP and barometric_P_i is for barometric correction, or both can be used for map external or internal at choise?

Yes, one sensor is for MAP (manifold absolute pressure) and the other is barometric pressure.

Though not necessarily 'required', barometric pressure sensing- along with ambient temperature sensing- allows you to more accurately determine the amount of fuel required instead of relying on some hard-coded values and letting the O2 sensor correct things. Another benefit of barometric pressure sensing is it allows the ECU to more easily correct for changes in altitude, like when driving in mountainous areas, without having to deal with the inherent delay the O2 feedback loop incurs.
