Here's a quote.................
"The software to run the engine is the result of years of effort. It has been enhanced to support engines from stock through high performance monsters. Handles boost to 30 psi. The EBL code provides functionality not found in stock ECMs. Wet N2O control, lean cruise, cranking prime pulses, ability to select open loop modes for cruise, decel or idle.
For example:
I do note that you can run either EGR or NO2 as they use the same pinout. But who want EGR anyway.

For example:
- A real shift light
- Soft touch rev limiter
- 1, 2 and 3-bar MAP support with boost SA retard and fuel multiplier tables
- Spark tables are high resolution and full size up to 6,400 RPM
- VE tables are high resolution and full size up to 8,000 RPM
- Acceleration enrichment (AE) tables have been expanded
- Changes to the fueling algorithms have been made to provide a smoother, stronger running engine.
- Electric fan, upper/lower on/off thresholds and override temperature. MPH threshold shutoff along with PE mode shutoff
- N2O wet system control: minimum MPH, TPS threshold, RPM window. Arming input
- Smart A/C control: PE disable, upper/lower RPM shutoff, re-enable delay
- Lean cruise mode for better fuel mileage
- Open loop fueling modes
- N-Alpha mode
- Emissions functions: EGR, CCP, and closed loop fueling
- For the Corvette CrossFire* folks your Digital Dash is supported. Your trip computer (DIC) will be functional
- For '85 through '89 Corvette, Camaro, and Firebird TPI setups**, changing from a MAF set up to the EBL Flash ECM is a snap

Pretty crazy stuff.
Thats pretty cool but you still have to manually adjust the tune in your truck. Where all the other ones self learn completely and there is nothing too it, no laptop required. Its cool you can have several different tunes, but you can accomplish the same thing with a prom burner and a few proms.
Idk if was something that Craig himself did wrong. But that whole self learning thing was not all that self learning on his. Heath had to help him screw with it a bunch to get it working well.
But could be something he did or didn't do....
I am looking at the EBL from Dynamic EFI for my TBI 454. I am going to do a head/cam/intake swap and don't want to mess with generic burned chips.
Its been a year since this thread got bumped.

EBL works well for me. Way easier than screwing with swapping chips, or extra wires hanging out of an add-on flash burner. The real time display is great, and basic fuel table tuning can be done in a semi-automated way.
The main downside is that it's still the comically ancient GM hardware. You are also still stuck using tunerpro for mods, which is great for what it is, but it's a 3rd party thing with way more capability (confusing detail) than _most_ people will ever want to mess around with. To put it another way, if you need to do something significant, you'll still end up on some forum begging for help because there's really no documentation. Having said that, the EBL guy has been great about answering my questions in email.
Megasquirt can do all these things and can even control your transmission, but for hundreds invested instead of thousands. Of course you have to figure a lot of it out for yourself, so it's kind of a think or spend decision.
EBL Flash is what I have. Current price around $400 depending on whether you already have a GM ECM.
Just out of curiosity, what megasquirt hardware do you recommend for TBI 350? I went to the web site and was instantly overwhelmed.

Same here on mega squirt being overwhelming! I am interested in adding injection to my recently acquired 396. I would like to do gm tbi as I think it would be cheapest, but really don't want to mess around with chips! Not looking for the hands down best performance, I just want it to run good all the time!
You would keep all your TBI sensors and throttle body and just replace the ECU with a MS unit. Somebody probably sells an adapter harness from the TBI connector. You could always go with a big block or aftermarket throttle body if you wanted. It's your choice if you want to keep the HEI or go with some other ignition system like a GM DIS, Ford EDIS or MSD box, etc. - they are all built into the base code.
Now you could also just set yourself up to burn GM PROMs and tune with those, but with MS you get a full set of tuning software for free and even the "self-tuning" SW is a nominal fee like $50. You also get full control of external relays for whatever you want. Most things you would ever want to do are built into the base code - like boost timing control, N2O, etc. You can even run full race cams with Alpha-N mode or whatever.
It's fully flexible - you can use the same controller for your lawnmower or turbo Viper, but the need to define everything and tune is what turns most people away. However, if you are using a well-known engine (such as SBC TBI, duh!) you can just download a file from the forums and have the engine running. Then tweak from there. A lot of applications look intimidating because the setup is so custom there is hardly any other choice for EFI. But starting on a vehicle that already has EFI in place, if you buy a pre-built ECU and adpater harness and have an old laptop it could be done in a day.

Is Megasquirt just the ECU, or do you have to buy their TB, injectors, Harness etc?
Megasquirt is a great system, can integrate with just about anything. But it is a completely DIY solution. You have to buy everything separately, set it up, make it all work together, tune it, basically everything. It is a wonderful platform for a DIY fuel injection system.
I feel the EBL system is better for a more casual user, EVERYTHING is based on the GM TBI system (for this discussion). Every part other than the upgraded computer is GM. Both systems require learning, but the EBL requires MUCH less and uses your existing system and harness. It will work with dual TBI, TPI, port injection, sequential injection, lots of options without having to build everything yourself. For bigger horse power the dual TBI is pretty killer. Taking two 450 to 670 CFM TBI's can supply a bunch of engine. For a mostly stock or mildly upgraded engine the EBL is perfect.

The only sensor specific to Megasquirt is the MAP sensor, which is built in. You choose what hardware and other sensors to run. If you base it all on a common factory system, there is likely an adapter harness available to plug in the MS ECU. As you get more custom, you will be building some or all of the wiring yourself. You can define the resistance curves for temp sensors. Almost any TPS can be calibrated in like 30 seconds. You can use a crank position sensor, optical sensor or get timing information from your distributor. You just pull down options on the setup pages to tell it what hardware you have.
