Megasquirt Progress, Main Board complete Options

[yarin]

Tonight I have completed building the main board for my MS II V.3.0 system. Thanks to those that have helped out. Once i'm all finished I will definitely post a complete "How To MegaSquirt a 914" website with pics and step by step. So far i'm still at the desk level. I've got 2.0 injection parts on the way.

I'll be using the following:

stock injectors
GM air temp sensor
stock fuel pump
summit racing manifold referenced fuel pressure regulator
stock injectors (i think 2.0s are on the way)
stock plenum / runners
stock CHT
MS Relay Board
Innovative WB02
High Current ignition driver
Stock dizzy with pertronix (hall sensor)
Stock Bosch Blue Coil
PWM Low impedence injector driver (no resistors)
Stock Cold start Valve (plan so far)
Stock throttle body with some junkyard TPS

Here is a pic of my board, took me a few hours a night every night this week. I took my time, double checked everything. So far so good!

I don't expect to have the system in the car for at least another month. I'm converting from carbs so I want to install steel fuel lines and clean some stuff up.

I'll be sure to post progress in the forums. (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

Yarin,

I have a similar setup to what you are planning, MSII/v3. A few hopefully helpful notes, you will need a 1k bias resister for the pertronix to work cleanly. I found the bosch blue coil caused noise on my system but others seem to be able to use it fine. If you plan on doing fuel first and just get a signal from the coil then R57 will need to be increased, I think mine is ~750 ohms. I started like this and recently swtch to having MS control spark. I did not have to change R57 back to the original value, it worked fine. I did have to change the predictor algorithm to "last interval" to get a stable spark output. I'm using a locked 009 distributor by the way. DNHunt posted a great timing table on this board, it works great for me, better then my old mallory setup especially at high rpms.

Where are you planning on mounting the boxes? I have the relay box mounted near the battery on the firewall and the MS box under the arm rest. I mounted the relay board in the lowest slot of the box and cut holes in the cover so the relays would fit. The cover makes it look clean but if I ever have to access the fuses/wires on the side of the road it's going to be a pain.

I hope this is useful.
