ok, i went through the faq a number of times, before i posted this but i just want to make sure were all on the same page, first ill list what i plan to do with my megasquirt then ill ask to be sure, what i need,!!>??

turbo, 12a with 2nd gen cas. coils etc. from stock 2nd gen ignition.

megasquirt version 3, or extra board... with a ms1 chip because ms2 chip cannot do wankle ignition, yet,...

i have a stimulator board already, i want a relay board since its a previousely carbed car,

was thinking about wideband, or egt, what else do i need or need to know, ??

i plan to use the 2nd gen cas with 2 teeth cut out, as opposed to modifying the megasqirt,


thanks guys, im glad we finally have a megasquirt section,, im learning lots,

Paul

 

I'm very glad to see that you're planning things carefully. I would add a wideband to your list, especially with a turbo 12A. Any of the recent units from wbo2.com or the Innovate stuff ( http://www.innovatemotorsports.com/x...me.php?cat=253 for example ) work well, I've personal experience with most of them.

cool so thats all i need, allong with a wideband!!, good,

i was just wondering isnt it a good idea to use evenly spaced teeth for the cas, ? like if were cutting 2 teeth off the stock unit that would leave a larger gap, does that effect the performance of the megasquirt ignition at all? or am i just crazy, that was my first thought,,,

thanks again guys,,

Paul

 

if you cut two teeth out, you're just changing how the megasquirt synchronizes with the CAS. it uses the missing teeth to know when the front rotor is firing vs the rear rotor. (that's very simplified).

That's the same thing the "G" wheel (2 teeth) is used for on a stock CAS, at least on the megasquirt.

 

You're just crazy! :-) Not. Like muy says, the 12-1 scheme works just fine.

PWM flyback damping circuit, (Optional),
The PWM flyback damping circuit is identical to that found on the flyback board daughter card, and is needed for low-impedance injectors that don't have resistors.

Hall sensor/Coil(-) and/or VR sensor ignition trigger circuit, (Choose at least one),
The Hall sensor/Coil(-) circuit is nearly identical to the ignition triggering on the V2.2 boards, and is suitable for Hall sensor, optical sensor, points, or coil negative terminal triggering. The VR sensor circuit is used to take the AC signal from a magnetic reluctor distributor directly, without an intervening module. You can install both and select between them with jumpers.

IGBT high-current ignition driver circuit, (Optional),
The IGBT high-current ignition driver can be used to control a single ignition coil, or some other high current device.

Current limiting circuit, (Optional),
The current sensing circuit allows for driver FET protection. The clamp current is set to ~14 amps. The current limiting circuit can be omitted if protection is not required or desired.

Sockets for all ICs, (Optional),
Additional sockets for remaining ICs (40-pin CPU socket is included in 'basic parts').

Spare parts, (Optional),
Spare FETs, voltage regulator, polyfuses, and crystal

Cables, (Optional).
External DB-37 connector and DB-9 cable for those who don't already have a harness, and PC/MegaSquirt cable.


ok another quick question before i order here, which of these oprions do i want/need, what impedence are rx7 turbo2 injectors,?(thats waht ill be running) at first, do i need any other options to run the ignition.?

what did you guys get from there and what was your reasoning?

thanks again guys,

Paul

 

another quick question,,, i already have a air fuel gauge, made by autometer,its meant for narrowband! but can i hook it up to this lc1 wideband controller or should i just sell it?
http://www.innovatemotorsports.com/x...me.php?cat=253
just for looks? would it be accurate? i want it just for a display besides the laptop,

will that lc1 wideband work with a megasquirt?

 

You don't need it if you're not going to use low impedance injectors without a resistor... I usually put those parts in anyway though just in case I ever feel like running some low impedance injectors directly

you'll want the VR sensor option...

you don't need it..

Keep that, even if you don't need it, it could help keep you from shooting yourself in your foot.

Depends on how good you are at soldering... if you're not good, get the sockets. If you are good, then don't.

This is totally up to you....

Also up to you.

The impedance depends on what year you have... but either way you have high impedance or you have a resistor pack... so there's nothing to worry about.

 

It would work, the LC1 has 2 programmable outputs, so you just program one of them to be a 0-5v signal that the megasquirt uses, and the other a 0-1v signal that the gauge uses....

yes.

 

ok i have one last question, how do you know absolutely everything about megasquirt and every component related!!!, you must read forums allot, or do you have a secret book your not telling us about a secret answer book to everything about life, cause ive got questions about life too,
