i cant imagine why you'd want to keep your mouth shut. if you know something, its gonna benefit us a lot more if you speak up about it.. even if it is an annoyance. id hate to be told how great a system is, only to find out the people recommending it, gave that recommendation while hiding a fault.

.. you dont even have to use EDIS, its just another option.. but i do think it would be helpful to know what problems the wheel is giving.

toyotaspeed90 · 04-09-2007, 07:28 PM

the only problem (and has presented itself with a 4agze and a 20V which had a 16V pulley) that i've had with edis is that if you weld the standard escort/tracer wheel to the end of the pulley... when you pull the pulley off it then hits the subframe of the car.... if you have to pull the pulley you need to unbolt 3 mounts and lower the engine about 2".....

there are other ways around using that thick of a trigger wheel however

TomsMR2 · 04-09-2007, 09:21 PM

eh.. i think us mk2 guys have to do that anyway

mildly annoying, but not a huge deal.

mr220v · 04-10-2007, 09:42 AM

Here's a thought, some of the later S series motors (that use coil packs) have a pickup on the crankshaft timing gear. The oilpump even has a mounting point for the crank sensor.

Wouldn't using these parts be much easier than trying to attach that edis wheel?

TomsMR2 · 04-10-2007, 10:10 AM

^ maybe, but then you'd have to go buy a camry motor and remove the balance shafts.

someone is tinkering to make it work as-is. edis isnt needed, its just another ignition option. the welds dont really secure it, they just hold in it place.. i remember years ago when people were running edis wheels, unwelded.

mr220v · 04-10-2007, 11:18 AM

My beams motor has this trigger crank gear, and I would imagine the gen4 caldina 3sgte would also have it. I know those would fit.....if you can find them.

The reason I'd suggest the late 5s is because those parts can be easily ordered.

So:

crank gear
oilpump
crank position sensor

TomsMR2 · 04-10-2007, 02:47 PM

you sure the ring isnt cast into the crank itself?

mr220v · 04-10-2007, 03:21 PM

Nope, its on the gear.

Mekkahfire · 04-10-2007, 07:14 PM

Did anyone ever find out if that guy created the open-source user-tunable factory ECU upgrade?

MikeV · 05-05-2007, 08:55 PM

I'm playing with a couple MegaSquirt projects now....

One is a prototype, running on the bench only, that I like to call "MegaSquirt 2-and-a-half." It is pure prototype, with multiple (5) boards and jumpers and wires.... but it's packed with features. It uses a MegaSquirt-II CPU to run spark and fuel and an MS-I CPU to drive lots of general-purpose IO. It also has add-on boards to support 4 coils, 4 low-impedance injectors, one EGT, two VR sensors and a few other goodies. With any luck this will be on my car in a few weeks.

The other project I'm playing with (I refer to it as "MSII on steroids") uses a Fairchild MC9S12X CPU in place of the Megasquirt II - with gobs more speed (40 MHz) Flash and RAM but running MSII/Extra code. Why? The added memory will let me run substantially larger table sizes, and the speed and 128-pin packaging means I can support as many features and IO as I need. This is a ways off though, so far I've only been able to play with the code on an eval board.

I may also try out a straight MS2/Extra system in on my car in the coming months.

Great to hear your experimenting with MS and developing your own ideas..that's what it's all about

If you get the oportunity post up a couple of pics of your prototype boards, and a few thoughts on where your going with it...

My 5-board monstrosity is simply assembled from other people's boards -- the MS v3 main board and MS-II daughterboard, the MSn/Extra daughterboard ("error* board"), Glen Hoag's 4x coil driver board, a 4x low-Z injector driver board, and a recently-acquired "extension board" which allows a MS I cpu to share all the input pins of the MSII daughterboard (and has taught me the futility of hand-soldering surface-mount devices at my age).

Enthalpy · 05-06-2007, 04:12 PM

I just had another car I tuned on a MS. It was an 20 valve silvertop 4A with ITBs.

One word: THROTTLE RESPONSE. Wow. What a motor!

The MS's hybrid control flat out stinks, so I went with temp-compensated alpha-N. I will do a baro compensation when he gets a 1-bar onboard. This was using MSnS 2.25 with v19 firmware, IIRC.

The controller wasn't bad. We had sufficient resolution on the maps. I would have liked more, but oh well. The MS controlled the variable cam timing, which is a 2 position cam setup, activated at high load. Don't confuse this system with a vvt-i system, which requires much more sophistocated control. This of this system as more of a vtec control, or an "on/off" type setup.

Spark and position triggering was handled through a Ford EDIS system with a 32-1 wheel on the crankshaft, IIRC. The MS can handle this triggering pattern quite well. Of course, this also means batch injection, which hurts mileage a little. Ford's ignitor system is nice. If you lose the MS spark signal, the EDIS system sets a 10 degree advance across the board for limping home.

We will head to the load-holding tuner's dyno this week to finish things up. We only street tuned the fuel and set a conservative spark map in. Since this is such an efficient combustion chamber, I don't expect much spark advance necessary during cruise.

If you are doing an alpha-N setup, give the system more resolution in the low alpha range then you expect. I knew it would need a lot, but I was surprised at just how much the motor wanted.

Mekkahfire · 05-06-2007, 05:14 PM

Yum, link to this car please?

Alesagol · 09-16-2007, 12:10 PM

I've soldered, installed an tuned 2 megasquirts, one was a carburaetor to efi conversion, and the other one just an ecu exchange, it's not that easy at the beginning but then you can achieve pretty good results. Any way you get a lot for the money you've paid. I'm planning to buy a gen 3 clip and install the MS I'll post when I'm done with the swap.

luke willmot · 11-15-2008, 01:05 AM

ok im new o hear so i have a spectre ems pro it uses a ms base and the same program but comes with every upgrade and more than the ms ecu .
i opend a thread on the subject i need the install specs for my engine its a 3sgte 1992 JMD spec i want to make it plug and play . got the plugs need help with pin outs and wich cable goes whare on the oem plugs. so how do i get my ems pro to receve the triger signal from the stock dis.
