targets aren't important at all. you should be going open loop in boost anyway.

yeah, i don't use gego. i run around 15.5-16:1 in cruise. accel enrich settings are in kpa per second, in other words its the rate of change, not the actual current pressure.

Ok so I suppose i am doing just fine with my target AFR;s then, i mainly am using them to let megalog viewer adjust my map. As far as the Accelleration enrichments, i think im gonna have to do some reading because while I understand the concept of enrichments for kpa/sec, I have no clue how the settings translate to real results. Anyway, im just happy to be on the road again after that stupid crank problem.

Here is my current map. I started off using Al's map, but it has been modified a bit since. The boost map is a little crude however as much of my tuning has gone towards getting a good cruise map.

P.S. I am running a Stock Fuel system with 550cc RX7 injectors and 1 step colder NGK plugs

Get rid of the FMU.
Just adjust your reqfuel for the 550cc injectors and use the MSQ they provided you.

Okay so I was checking out the file someone posted here as "scottsmap" and also the "turbo 11psi" and I noticed a few things in Megatune. Why does it not allow you to see what the injector sizes were for the maps, also, I noticed that the exhaust settings were using wideband not narrowband. If running a narrowband, do these parameters have to be changed as per the MegaManual?

Megamanual is the bible for megasquirt, always follow it.
Who cares what size the injectors were, you should always change the req fuel for your own car.

no don't keep it. I messed around and played with tuning on one and it was a pain. Pull the auxillary fuel pump as that seemed to cause problems as well with getting a consistant tune.

the injector size is the Reqfuel it's part of the calculation,

Of you course need to alter settings if they're different from you car. MS is good, but it's not bloody psychic.....

Unless I'm reading wrong... do we have any boost MS maps for a 1.6L with 560cc rx7s? Something to start up on... if we get oil lines made in time... I should be start up-able tonight....

Just take whatever's the closest match, and then:
1) note the req_fuel value
2) recalculate the req_fuel for your 560cc injectors
3) modify cranking pulse widths, accel enrichments and any other millisecond-based enrichments with new_value = old_value * (new_req_fuel / old_req_fuel)

That should certainly get you close enough to start up.

Is everyone using AL's spark map as well? I've read a bit through the manual, but spark tuning looks a little daunting to me. How will I know if my spark map is optimal?

without a load bearing dyno and a set of detcans you never will, an experienced tuner will get you close though.

if your road tuning yourself, just slowly increase the timing, use your butt dyno as a guage and get yourself a knock sensor as a safetynet
