Another Newbie to EFI

[briankmizell]

Hello, I am Brian. I have a 1989 B2200 that was originaly carbureted, I have put all the parts from a 1993 B2200 that was an EFI engine.

I have talked to some guys at a mazdatruckin web site, several there have sugested the MS II v3.57

So I talked to Ben Berusch and told him what I have & what I wanted to do. Below is the list of things I bought from DIYAutoTune.

Hello Brian,

Per our earlier conversation, I have modified your quote as below:

MS2357-C_BL $411 Assembled Megasquirt-II with V3.57 PCB , black case
MOD_x357-12vIn: 12v Pullup on the Ignition Input $12
MOD_2357IGN1: Single Ignition Output through BIP373 coil driver $20
MSStim22-C $69 Assembled Stimulator
MSHarness $65 12' wiring harness
IATwPiggy $22.25 Intake Air Temperature Sensor
38NPT-BungSS $9 steel bung for IAT sensor
TuneCable $5.50 6' DB9 tuning cable
USB-2920 $20 (Only needed if your laptop doesn’t have a true DB9 port)
Subtotal without wideband-- $633.75
Shipping: $19.50
Shipping Insurance: $7.80

Grand Total: $661.05

I have done a subsantial amount of reading of the megamanual. I know it says to read it all, but so far what I have read is just basic info about the design of the MS II and who did it and why.

Since my MS II v3.57 came pre-assembled, can I just start Hooking it up following the wiring schematic instructions and then start tuning?

I am anxious to get this thing going, but i dont want to jump the gun and do anything wrong.

Any info is greatly appreciated.

I hope this isnt too much, but I wanted to add the answers to the questions Ben asked me when I inquired about the MS II v3.57


1. What year/make/model/engine/tranny? (Pretend you're at the parts
store, ordering a starter.) If this isn't the original
engine/electronics let me know that too.

1. 1989 Mazda B2200 2.2L automatic transmission, 3.909:1 rear axle gear ratio.


2. Are you looking to control fuel only, ignition only, or fuel and
ignition? Is there anything beyond these features that you are looking
to control - fans or boost, for example?

2. I want to control fuel and ignition, Fans, idle speed when put into gear, idle speed when A/C is turned on, idle speed when power steering is turned all the way to the left or right, Idle speed when alternator kick's in and slows the rpm of engine. (I have 140 amp Alt from a Mazda 626), I don't plan on installing a turbo.


3. What are the engine details (type, number of cylinders, previously
fuel injected or carb'd?)

3. 1989 Mazda F2 4 cylinder, originally 2184cc bored .020, decked .003, main caps were line bored, piston rods resized and shot peened, Speed Pro 8.6:1 pistons, 8 valve SOHC Head, pacesetter header installed, 2" exhaust turned down just before the rear axle (It probably needs to be 1 7/8") to increase back pressure. It was previously carbureted (holley 5200) the motor will rev pretty easily up to 6400 rpm when in neutral. when its in gear and under a load while driving it starts loosing power around 5000-5300 rpm When it was carbureted it didn't have much torque at all until it reached 2500 rpm or so. i have not driven it since I have put the EFI intake & HAL effect distributor.


4. What type of ignition system does your car run- where is the crank
angle sensor (CAS) or distributor trigger wheel and what type is it
(Optical/LED Sensor? Hall Sensor? VR Sensor?)

4. I have a distributor from a 93 B2200 that was EFI, I think its a HAL sensor distributor (if that makes sense) I have both the factory coil for the EFI b2200 and a MSD Blaster2 coil, I would use which ever you recomend.


5. How many teeth/windows/slots and what orientation does the CAS, crank
trigger, and/or distributor wheel have? (any missing? all evenly spaced?)

5. There isnt any teeth on the crank pulley, As for the distributor wheel I assume you mean the gear on the end of the distributor where it meets up with the cam shaft. It has the teeth in a slanted or spiral angle and they are evenly spaced, none are missing.



6. Is there a distributor? Single/Multiple Coils? Coil on Plug?

6. There is a distributor as previously mentioned, there is one coil (its the factory coil for the 93 B2200 EFI engine, distributor has a cap with one coil wire and four spark plug wires.

7. Does this engine have a fast idle valve (IAC)? If so, how many wires
are connected to it? Do you know if it is an on/off, pulse width
modulated, thermal, or stepper type?

7, There is what I think is a MAF (its in the cold air intake right next to the air filter) I have no idea if its on/off, PWM, thermal, or stepper type.


8. Rate yourself 1-5 on technical confidence in yourself. 1 being "I
can't paint by numbers" and 5 being "I can probably build a car from
scratch if I have the right documentation, and I'm resourceful enough to
do some research and find some of my own answers." I need to know this
as some of the 'less traveled' roads will require you to make
modifications that in some cases I haven't performed myself yet and
based on this response it will help me to know whether this type of
solution is for you or not. I challenge you to 'stretch yourself' a
little bit. You won't ever learn anything (about yourself and your
abilities) if you don't try to do things that you're not quite sure you
can do... and then find that you can.


8. 5


9. Are you looking to build your own ECU from a kit or buy a
pre-assembled ECU?

9. If its not very costly I would prefer to get one pre-assymbled.


10. Are you open to retrofitting a different ignition system such as the
Ford EDIS distributorless system or one of our crank trigger kits if it
is determined that the MegaSquirt will not properly (or easily) control
your factory ignition system? Many factory systems MegaSquirt can simply
take control of, some it cannot. EDIS to the rescue! It's cheap, simple
and works great!

10. I would prefer to use my HAL effect distributor if it will work.

It looks like you are headed in the right direction. Keep reading the MegaManual, it is a wealth of information. If you have a lot of automotive experience, you shouldn't have too much problem with the build. Learning to tune EFI will take some time. It's not particularly complicated, but knowing how things are done in an EFI system is part of the learning curve. I'm in the tuning phase with my motorcycle conversion, it gets better every ride.

If you can find someone else that has fuel injected the same engine, that would be really helpful. Just get their .msq file, which will contain all of the configuration and tuning data. You will have to tweak some parameters depending on your setup, but it helps considerably to start with a known, tuned configuration.

Good luck!

I'm am moving along at a snails pace, I got my MS II v3.57 powered up. I had an issue with windows 7 not acknowledging it.

Come to find out that when DIYEFI.com sent it out they didnt strip the insulation on the power wires for the 9 volt battery. It wasnt making connection, so I fixed that.

Now I need to get the sensors calibrated, harness wired it up and start tuning.

Any one here ever do MS II v3.57 on a Mazda F2 2.2L, Mazda 626 or an MX6 2.2L they are the same engine block. It just has to have the 8 valve head and not the 12 valve head. If you have and wouldnt mind sharing your calibrations and or setings, I would really appreciate it.

Check over at MS Success Stories: http://www.msruns.com

There seem to be some Mazda B2200 EFI conversions posted.

Good luck!

Will do,

Thanks!
