With a 60-2 wheel spinning at crank speed you'd have too many trigger events (that would be enough for a 10cyl). As per the ignition article linked above you'd need 5 teeth at cam speed which is half of crank speed. The good news is you can use a 60-2 wheel with MSnS-E or the MS-2 (with distributor) and use the wheel decoder feature. I don't have as much first-hand experience with the wheel decoder as I do with standard trigger wheel/distributor installs, but the guys on the MSnS-E forum, or the MS-II forum could help. The MS-II wheel decoder firmware is in beta right now and soon to be released, you can get the beta though if you wanted. The MSnS-E guys have been doing this forever.... www.msefi.com MSnS-E's wheel decoder can be used for wasted spark or COP as well, and the 60-2 wheel would work fine. This is much more complex though.... And as Tadek said the MAP sensor is builtin to the MS and the standard sensor is good for 21psi of boost. I do have the 'MapDaddy' dual 4-bar sensor with baro correction, which is good for 44psi of boost. It works with any MSnS-E or MS-II ECU. MegaSquirt-I PCBv2.2 – By default a fuel only controller. Free MSnS-E firmware allows full fuel and spark control and a ton of other features. This is cheap, feature packed, and works great. If you are running low-impedance injectors you should also pickup the ‘Flyback board kit’ as an upgrade to the unit. Kit is $134, flyback upgrade kit is $25. Assembled units w/o flyback upgrade are $240. MegaSquirt-I PCBv3.0 – By default a fuel only controller. Free MSnS-E firmware allows full fuel and spark control and a ton of other features. This unit is affordable, feature packed, and works great. Has several upgrades making the unit more robust and harder to damage with a wiring mistake. Also has circuitry to directly drive a coil without an external ignitor (with MSnS-E). No upgrade needed for low-z injectors. Kit is $189. Assembled units are $330. MegaSquirt-II PCBv3.0 – This is the latest/greatest unit with lots of new and improved features including a finer degree of fuel control (great for tuning idle with large injectors) and native ignition control. This is an affordable and feature packed unit that was just recently released and will be further developed to add more and more features over time. As this is based on the PCB3.0 it also has several upgrades making the unit more robust and harder to damage with a wiring mistake. Also has circuitry to directly drive a coil without an external ignitor. No upgrade needed for low-z injectors. Kit is $250. Assembled units are $410. What is the difference between the MegaSquirt PCB 2.2 and the PCB 3.0? They are both able to use the MegaSquirt-I CPU or the MegaSquirt-II daughterboard, but they are based on different versions of the circuit board. All of the improvements with the V3 board are listed here: http://www.megasquirt.info/ms2/pcb.htm The main high level differences are that the uprated flyback circuitry is included so you can run low or high impedance injectors, there are several improvements to make the board more robust and harder to damage in the event of a mis-wire or overload event. A prototyping area was adding to the PCB, and several changes were made to prepare the board for the future including the now available MegaSquirt-II CPU and upcoming releases such as the GPIO and Router boards.
