The Megasquirt from CIS-E and Motronic Official Post!

[Mouth]

Good day people,
I have a buddy with a 16v & ITB's setup.. We need to get this car up and running with this stand alone. We are in need of the standalone and the installer. We are located in new jersey and are wiling to travel within reasonable distance to get the job done.. Please if you or anyone you no can get this done please get back to me ASAP..
Thank you in advance

1990 VW Passat 16v, MS2 v3.57 MSnS extra 2.10d, distributer/hall directly driving a single coil

The ignition input is still a little uncertain to me - I understand that there are lots of ways to make it work, but that doesn't really make me feel better.

My hall sensor is an open collector. With a 12v pull-up on it's output, it gives me a nice going-high signal, lines up with the rotor with a measured trigger angle of 90deg. (apparently this is *supposed* to be about 60 on my engine?) Rather than installing the resistor in the harness I installed it internally, and since it seemed silly to go to 12v and then back down, I went from the 5v supply pads to pin 24 and jumpered D1 - figured I would try that and then jumper D2 if needed. And now my Megastim (v2.21) tach input doesn't work? Then I realized that R57 is sitting there, a perfectly designed spot for this, so I am installing the pull-up resistor there, but I don't see that making the stim work.

What is "trigger return" vs. "basic trigger?" I've been looking...and looking...and looking, and still don't know what this means? And, if I understand correctly, the "angle between main and return" is the duration of the low/ground output?

Thanks to all!

not often this thread is being used anymore.. thats not good..

anyhow. just need some info

me and a friend of mine is trying to get an audi 90 with an inline 5 cyl to run nicely. (10v turbo)

this is essential the same as any other vag engines, we are using the BIP module, and direct coil control, the car starts, and run. but poorly

so my question is. doubt that i'll get some good answers, but i'm trying


what are the constants we need?

1 or 2 squirts pr cycle?
trigger rise, og trigger return?

running stock distributor and coil. clean ignition signal


and very unsure on HOW to set the timing correctly. we can't seem to get anywhere. and are soon one year into the tuing :s


and about dwell. what should that be?

time after spark?
fixed? etc

running MSII v3.57 with MS2 extra code


I'm crossing my fingers for any good answers. we are soon about to give up

[Richago]

Well, I just got mine running. I still don't 'get' everything (can't figure out how to data log), but I think I can answer a few of these! I'm actually running the same code and same computer, too!

Because you have an odd number of cylinders, you can run 1 or 5 squirts per cycle, simultaneous only. "You want this to be set so that your idle pulse width is no less than 2.0 ms, if possible, and your Req_Fuel is less than 12-15 milliseconds, but more than 8 milliseconds. These values allow proper tuning of the idle mixture while maintaining the ability to apply enrichments (acceleration, warm-up, etc.) under full throttle. This is the total injector events that you wish to occur for every engine cycle (360 degrees for two stroke engines and 720° for four strokes)."

With the hall sensor I believe you can do either. Basically, it's the difference between the rising edge and falling edge of the hall signal output. Once the car is running, setting the timing "correctly" is easy - you just verify that the number MS shows is the actual number you see with a timing light, and adjust it by either changing the trigger offset or adjusting the distributor.

I have max dwell at 3ms, max spark at 1.5, and cranking dwell at 6. This is most important at high rpm where, if there isn't enough time for both, it will shorten both based on this ratio.

And, in case you haven't been using it, the MSextra site is way more helpful than the regular one: http://www.msextra.com/doc/index.html

[weejunGL]

we have it set up to run 1 squirt pr.cycle now. and simultaneous. our main problem is that the car stutters like crazy when under load. and don't get much boost. altho its set to about 1bar atm

i've got a vid, showing the idle, which is pretty good. and it will rev "good" enough when under no load

and engine (don't mind the owners dog. or the "fox" as we call her :p )

[Richago]

The revving seemed a little sluggish to me - maybe give it some more ignition advance? Have you checked the timing with an adjustable timing light yet? Do that first. And, do you have a wideband O2 sensor?

[weejunGL]

he has set it with a standard timing light, goign to adjust it with a good adjustable timinglight this weekend

we got an LC-1 on there, but the controller suddenly stopped working, but a new one is on the way

its a little sluggish yes. but idle is great. and its even more "sluggish" when you are accelerating with load. i'll see if i could get a hold of the msq of the ecu

Hello,

Can anyone help me with choosing best MS for 16V Turbo ( 2.0 9A ). I want to run coilpacks, boost controller, wbo2, egt, knock sensor and sequential fuel+spark control. My friend told me that MS3 will be the best for my needs but this will be my first steps in standalone ( for now I tune Digifant I ECU's only ) so I want to talk with some more experienced people.

[weejunGL]

you don't really need MS3

you can get away with using MS2 v3.57 with no problems

[qbejs]

Ok, so one more question. MS II SMD PCB3.57 will run knock sensor without any changes in pcb ? It will be great to find megasquirt which will run all my wish list without modifications in pcb.

good info guys

[Scirocco16vGTX]

Hi guys,

Just registered myself so I could "abuse" this topic (fantastic topic by the way!!!!!!!).
I'm Chris aka Scirocco16vGTX, I'm from Belgium (Europe) and I'm currently preparing a VW Scirocco 1986 with 1800cc 16V (KR spec) engine.
Engine is fully overhauled with overbore KS pistons, sporty Cams from CATCams, full Supersprint exhaust ect ect..

Now I am in doubt to run the OEM K-jetronic, do a Weber-conversion or go full bananas meaning Megasquirt!!
I can buy a "90% complete kit" from a friend (who dropped his project-scirocco due to little time), I would only need:
* custom fuel rail
* a custom wiring for my ignition
* some basic (injection & ignition) mapping data, to start playing with

Anyone here who can help me out?
I already tried the "VW Megasquirt forum" but very little respons over there I'm afraid....

[Dave926]

What do you need to know?

[Scirocco16vGTX]

* a custom wiring for my ignition
* some basic (injection & ignition) mapping data, to start playing with

those are the most important as for now I guess

anybody knows if I can use an aftermarket fuelrail which was designed for Corrado 16V, on my Scirocco 16V? I'm in doubt because the intake is on the other side!

No it won't. And honestly knock sensors are overrated at least with MS (they don't work all that well). BUT..... the developers are working on a totally new way of dealing with knock sensor input.

and lastly while you do have to make some mods (minor) to the board, KnocksenseMS is probabaly the best working knock sensor set up available for MS. And it should work really well when the new code is done.

Bump ! To much good info to let go to waste!! Superb work guys,to all that have shared their knowledge i'm very gratefull and hats off!! To all of you.Roderick

[jfg69]

^^ I agree! Hoping to get a MS project started on my Mk2Gti very soon, the info here is going to come in handy!

[.:RDUBBIN]

Working on a 2.0 16v. Puttin it in an '80 caddy, and going to run ITB's, (GSXR Throttle Body with TPS) and MS1. I am a Noob to all of this, and am trying to figure it out for myself. I have a buddy that is walking me through it and he knows what hes doing, but i dont want to get to into it and have no clue how i got there or where to go if I cant get his help. Looking at buying MS1 PCB 2.2 or PCB 3.0. Would like to see this thread stay alive and know where to go to post my questions as they come up. Will be buying MS here in the next few weeks. Any opinons out there on PCB 2.2 vs. PCB 3.0?

Do not waste your time with a v2.2 mainboard. For that matter get an MS2 not an MS1. MS2/Extra has direct firmware support for ITBs. It will be much friendlier on the street.

[Jackasic]

I think I have figured our the ignition wiring with my HAL dizzy. last hurdle is injectors. Most diagrams show a set up for sequential, my G60 injector harness is set up to fire them all at once (batch). do I just tie the two injector signal wires coming from the MS box together?

This seems wrong for what I have, I know the ignition is:

[Prof315]

If you are planning on using the g60 injector harness then just use INJ1. And be sure to use simultaneous injector firing only. Personally I would connect INJ1 to cylinders 1 and 4 and INJ2 to cylinders 2 and 3 and use 2 squirts alternating. I do all of my batch fire installs this way and get good results.

[need_a_VR6]

If you do only use one output be sure to double your req_fuel or your VE will be very high and some other settings won't make sense.

I'm with Jeff, wire the other driver unless you have a really good (lazy would swing me!) reason to not.

[SpahnDirge]

Edit: Nevermind got it running near perfectly now!

I've been on the search for a well put together MSQ file, preferably for 029y3/4 code.

The engine is a:

9a block
kr head
autotech cams

using MS1 V2.2 with the 029y4 extra code.

Would be very much appreciated, as everything I've found is barely put together and from over 5 years ago!

[Jackasic]

i am kind of flummoxed, here is what I have so far. Motor is a ABA 16v with 260 cams, g60 injector harness, HAL, Bosch modal, and an ABA throttle body. Basically I cam make it rev to 7500k but I can't do it under load. if you dab the throttle it just dies. it acts like there is no accel mapping (which there might not be)

[StinkBugz]

I remember talking to someone here in PA that deals with MS and I forgot his info. I think it was Ken or Scott or something like that. The person has in depth knowledge of the VR application and I would like to speak to you again. Please PM me your info so we could chat again as I have a cabby that is getting a vr swap this weekend and MS is on my list of things to do.

I am just starting to convert my race car to MS. It runs in SCCA Improved Touring B road race and the rules there limit mods. Until a couple years ago, we were stuck with stock fuel systems. So now that the CIS-E can go, I am having at it. Car is a 1986 GTI with 8V RD motor. The mods are few. Blueprinted, a tad of port cleanup (rules again!), header with open exhaust, and now some freedom on the intake and fuel. Must retain distributor, stock intake, and TB.

So I have on hand or on order:

MS3
MAF
TPS
18 lb injectors + BBM rail
WB Lambda
Crank 60:2 Trigger Wheel

I'll start wiring soon, but in the meantime I am looking for a close MSQ file to use as a starting point.

Don't bother hooking up the MAF (just jam the trap door wide open) . The onboard MAP sensor in the MS3 will work just fine for measuring load

[JimLill]

I took off everything from the atmosphere to the TB already

I have a large K&N routed through 3" duct to the TB. The MAF is a simple add with cheap stuff (<$70) on that 3" duct.

[vr6unplugged]

I have a MK@ GTI K jectronic, since you have so mucho knowledge I am thinking about a fuel system install with a megasquirt/ for natural aspirated i love to gain some horsepower with new higher camshaft.... what would I need in order to have a succesful setup. As far as the megasquirt install goes and what parts are needed/// if you or someone you know sales the harness for the injectors and the Meagasquirt ECU, that would be awesome.

Thankls in advance just bouth teh car and love to have a nice daily driver.
