He is talking about burning new ROMs for the ECU. I agree about the choice of switching to MAP tuning but you'll have to tap the manifold for the MAP sensor. Not sure if the MegaSquirt can control the MAP. It might but unsure... The Hydra, Link, ViPec, or others in a little higher price range can. I haven't looked at what MS offers lately so they may have updated enough by now...

yeah i dont want to have to screw around with burning roms and crap.

megasquirt has a built in map sensor, so you just have to run a vacuum line from the ecu to the intake manifold.

then you just have to run basic sensors IAT, Water temp, TPS, IAC, wideband, then a ford edis-6 module for spark control, and fuel timing i believe

reasons i want to run megasquirt specifically are:

- no more MAF sensor
- extremely simplified wiring for a cleaner install
- boost control
- extremely low cost compared to competitors
- a sense of DIY accomplishment
Enjoy ****ty closed loop operation, and your 80's GM based system. There is no reason to deviate from the stock ecu until you outflow the z32 maf sensor, circa 550-600hp

burning roms is a millionth times easier than creating an entire ms system from scratch

So who has the hardware to copy a rom? Not me. And unless the microcontroller in the svx ecu has and IDE package that can be programed in C, there will be much difficulty interpreting the machine code that is needed to program the rom. I think putting a kit together would be much simpler than reverse engineering a microcontroller and the information stored on the rom. Plus MS is not gm based. Gm sensors are just plentiful and cheap. The MS kit can be calibrated to any car and sensor combination just like any other stand alone ecu. If you have the technical know how to burn rom chips than building a MS system should be very simple.

Here is a pic of the MS3 kit I ordered last week.The package arrived in 3 days.

Baby formula not included.

im glad you said what i was gonna before i did.

now i dont have to type it out.

i'll most likely be going with ms2, using an edis-6 module. i'm curious to see your results with the ms3, maybe it'll sway my decision

Pretty much everything you'd want to know has been defined, but if it makes you feel better to refute that, so be it.

Everything that has been define about the ecu... Has that been released to the public like the open port project and ecu flash? All I know of is ecutune, and there information regarding the svx ecu is a company secret.

I was going to go with MSII but MSIII has a freescale microcontroller dual core 16bit, build in usb support and an sd slot for data logging. I used a usb to serial converter when using my innovate wideband and ecuflash. I just did not like the quality of fit. It just sort of hung there.. too heavy in my opinion. So to keep it simple I opted for the built in usb. At $100 dollars more than MSII I would go with the simulator and the MSIII. Together they cost me $437 shipped.

As for ignition I myself am going to used the ford edis-6 module, and a coil pack from a taurus in a wasted spark setup. When I bought my engine the coils did not come with it. And at $50 dollars a piece, nope... not when I can get the taurus coil pack for $30.

MSIII has many additional features that I can't mention at the moment and will probably never use, but it is nice to know that they are there.

speaking of megasquirt, got myself a megasquirt 3 with ms extra, and a diyBOB that way i can utilize all the stock sensors and wiring. no 1980's based gm system, or complicated wiring, the harness from the BOB to the MS3 should only take 20-30 minutes or so. plus fuel sequential spark and fuel

Well I have the ecu completed. Seems to be functioning correctly. The engine is in place. As for the wiring. I have not made it anywhere yet. My gf's brother's sister, brought her daughter over here with strep throat and did not tell anyone. To make it a long story short. My 10 month old got it. my four year old got it. My gf got it. With everyone sick and my car 40 miles away at my dads. I havent had anytime. I have wasted all of may and most of june. I was hoping to at least have it running by august before school starts back up, but with all the tropical storms here in florida I fear it will not happen.

are you going to be running it with the megasquirt right from the get go?

if so, are you using the edis-6 with the 36-1 trigger wheel, and the ford coil?

I have my H6 Eg33 bugeye running on MS3/3x with no problem. ****ty closed loop? mine runs like factory and uses PID to maintain the desired afr when it deviates due to ethanol content.
The stock SVX ecm has no where near the features of the MS3 and if you know what your doing with your megasquirt you'll have it running 100% as good or better then the oem offering.
OP, if you need any help with the wiring aspect or would like to pick my brain/copy of my tune just PMme.

use the front 12 tooth section of the EG33 (if you have kept the H4 ecm for emissions, you can copy my homework and machine the second trigger off/ press the 36-2-2-2 on to feed the H4 ecu for tach and emissions inspection) and the cam sensor for your second trigger. It's that easy.
Be carefull of the documentation for the factory ignitior on ALLDATA. The wirng code for each cyl was inccorrect and ate a starter gear as a result. If you need to, use output test mode to verify the correct firing order for your coils. That was the only hurdle I ran into. Aside from that the harness merge although tedious was straightforward and the motor fired right up once I got the ignitor wired correctly.

So I finally found time between school to set the engine in place and all the bell-housing studs nuts and bolts are MIA somewhere in my fathers garage. Anyone have a set they sould sell?

So after waiting all summer and fall I finally acquire the time and money to complete my EG33 swap. But as always Murphy's Infallible law holds true. Today my babysitter had a stroke. And the left side of her body is now paralyzed. Is there anyone else out there with luck like mine?

...Only in Florida...



Seriously that sucks though. My EG swap had it's share of twists and turns, but working on it a little each day (even if it was just one bolt or one wire) and it got done. Its when you let a project sit that it fails.

That would be nice, but my car is 60 miles away at my fathers house. (My father can only handle toddlers in small doses)

Yes, I used one of the generic outputs (assigned to injector "h") and wrote a table that closes it down from 1500-4400 when under load greater then 40kpa. Works like a champ.
I keep adding more features, launch control, flat shift, E85 flex fuel switch for dual tables.
6500miles of straight no quarter given asskicking and climbing. I love MS3!

So with the persuasion of a big hammer the big block eg33 is now sitting in his new home.
And with the way it looks, if I remove the hood latch and notch the crash bar I should be able to fit the radiator, condenser, and fans.

Baldturbo do you have any pics of your fab job for the exhaust and the radiator?

Really any pictures of your swap would be of great help.

I have been building an eg33 100mm overbore custom crank, custom rods... its been about 4 years now, I am finally getting back into completing it... I will be using iron sleeves, full rebuilt heads, custom cams from delta 5 angle port job....All the bells and whisles, Borg warner s475 turbo, twinscroll, link full stand alone..........1200 cc injectors, custom fuel rails, dual 60mm wastegates..... Much more than that but cant remember, you can use a saab radiator that fits inside the core support.... no modifications necessary, as for the starter you tap the tranns..........Im gettin back into it and want to get it done by the end of the summer....( i know its winter)

I'm envious! I would love to be able to do with mine. Only utilizing a Holset he351ve. School soaks up my time and money right now. But by the time I can afford the build, my engineering skill should be able enough to develop electronic means to controlling the variable hot-side.

Railguy, I have a question about the Saab radiator. Will that radiator fit with the the ac condenser attached up front? I live in Florida and my car is black.

I just set the engine in Monday and it was 80 degrees out.
