...I get this.
I'm just starting out on this endeavor and want to learn the ropes slowly. For now I have an na car that I want to remove the maf from for a little power bump plus be able to pass emissions. I've acquired an EMU on the cheap so I'm just trolling for a little help.
I assume you are referring to this-
1- Megasquirt (Do-It-Yourself)
Manufacturer: DIYAutoTune.com Megasquirt Kits / Assembled Engine Management Systems, Wideband o2 Sensor Systems and tuning products
Price: $150 - $250, depending on CPU.
Additional parts: Air temp sensor, wiring, various "mod-kits", averaging $50-$75. Wideband O2 sensor / gauge, avg $250 (AEM). Injectors, averaging $50 - $200, depending on how good a scavenger you are.
Opinion: This is as DIY as it gets. In addition to physically assembling the unit (with a soldering iron) you will be required to perform various hardware "modifications", flash software onto the CPU, figure out a fair amount of wiring, and generate your fuel and ignition tables from scratch. That said, I personally use a Megasquirt-I.
Pros: Cheap. Versatile. Excellent forum-based support.
Cons: Very high initial learning curve, little to no manufacturer support. Not currently compatible with NB alternators, some creativity required to support A/C.
2- Megasquirt (Plug-n-Play)
Compatibility: 90-97, possible NB support in the future
Manufacturer: MegaSquirtPNP by DIYAutoTune.com (also Bell Engineering)
Price: $700 - $725
Additional parts: Air temp sensor: $30. Wideband O2 sensor / gauge, avg $250 (AEM). Injectors, averaging $50 - $200, depending on how good a scavenger you are.
Opinion: 99% of the capability of the true DIY unit, in a fully assembled, plug-n-play package. The software is mostly done for you, though dyno tuning is recommended for abnormally aspirated cars.
Pros: The least expensive plug-n-play system on the market, good vendor support.
3- Hydra Nemesis
Compatibility: '90 - '05
Vendor: Flyin' Miata : :
Price: $1,900 - $2,000
Additional parts: Injectors, see above, or buy new from FM for $415.
Opinion: Appears to be a very capable ECU with a proven track record.
Pros: It's supported by FM. Comes complete and ready to plug-n-play, including WBO2 sensor.
This is great stuff just not for me right now.
