My name is Brian, I have a 1989 Mazda B2200. Below is a list of the Megasquirt parts I purchased.

Speed Pro pistons (guesstimated Comp Ratio 8.8:1)
Speed Pro Molly rings
Clevite 77 rod & main bearings

The truck was originally carburetted with a Holley 5200, I wasn't happy with that so I chose to go with EFI. I used all stock parts from a 1993 Mazda B2200
What specs I do know about the EFI parts,
Injector size 270cc
Throttle body size (not sure)
Stock B2600 in tank fuel pump
Stock fuel pressure regulator
All rubber fuel lines were replaced with High Pressure hose.
Fuel line supply 3/8"
Fuel line return 5/16"
I used the distributor from the EFI engine because it is Hall effect distributor, it has electronic advance instead of vacuum advance
I have probably gave way too many details, but I wanted you to be informed about the truck. My reason for this is because I would like to know if anyone here has msq files for a naturally aspirated Mazda 2.2L engine that they wouldn't mind sharing with me.
I am completely new to EFI, I am eager to learn what i need to in order to get a good tune and a reliable vehicle.
Any info or tips are greatly appreciated.
I am getting there slowly, I'll post what wires hook to what and what color they are so that anyone else with at 90-93 B2200 can do this with out having to do as much research as I have been doing.
At any rate, I thought I would post some links to the Megamanual site that I think might be a good place to start reading.

I have a 1989 B2200 that was carbed, I have put all the parts from a 1993 EFI B2200 on my truck. I am using MS2 v3.57, it has the mod to run directly a driven coil
(I am using the MSD Blaster2) and the stock Hall effect B2200 distributor. It's a naturaly aspirated engine.
I need some direction setting up the config for my MS2, I keep reading and reading the megamanual, and many other pages on the site. But it seems I keep reading in circles, I am not getting anywhere.
What I do have set up is my IAT, CLT sensors, the MPX4250 MAP sensor, and the required fuel for my engine (well part of the required fuel). I am using Tuner Studio, but if I have to I can use MegaTune.
I'll start of withe the questions.
1. Req_fuel........below in bold typeis what I have set, tell me if it needs to be corrected.
Control algorithm percent baro this one & injector staging are 2 I am really not sure about.
Squirts/engine cycle 2
Injector staging alternating
Engine stroke 4
Number cylinders 4
Injector port type Port Injection
Number of Injectors 4
Engine type even fire
2. More engine constants.....
I have no idea of what I need to do here?
3. injector staging......
3-a. My injector's read 6.04 ohms with 12.75v going through them. The manual says if they read 10 ohms or more to set one way, and if they read 4 ohms or less to set another. Since mine read somewhere in the middle, which should I choose?
3-b. Also should I choose to turn on specific bank 2 setting? All my injectors are the same 270cc output
4. Tach input settings?
4-a. Spark mode basic trigger Do I choose basic trigger or trigger return for a Hall effect distributor.
4-b. Trigger angle/offset(degree) since my timing is set at 6 dgrees BTDC I though thasts what this should be set at, ist that correct?
4-c. Angle between main and return(degree) 50.0
4-d. Ignition input capture falling edge
4-e. spark output going high inverted
4-f. spark out put D14
Heck I could go on and on here, if you think that your MSQ will help me get a base setup (mine is a F2 2.2L NA) could you send it to me at email@example.com
Thanks in advance,
