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)

QUOTE Where did you guys put your fuel pressure gauge? I've seen an inline adapter, but i'm not crazy about adding two more fuel line clamps. Mine is mounted in the stock location. What's a couple more clamps? I think I used 16 in the engine bay...

Just more opportunity for leaks. I just drained the tank and removed the carbs tonight. The SS lines were fused to the cheap crappy plastic T that splits between both carbs. While trying to pull it off it split in 1/2. All that stuff is going straight in the garbage. No engine fires for me.

I had some time to plan placement of the MS and relay board. I've decided to add a little shelf in the corner next to the stock relay board mounted to the back side of the firewall. I already have 6 bolts I can play off that are being used for a race seat and harnesses.

Right now I don't have a rear window, eventually I'll cut one out of plexi because my roll cage ties to the rear shock towers. Here are pics of my car the day i bought it: BTW i'm looking to sell that Kirkey seat, it's a great race seat abut i need to drive this to and from events. Presently the car is registered and insured, just never really got a change to drive it because of never ending carb problems. http://coewww.rutgers.edu/~yarin/my914/

So I was poking around came up with an interesting idea. Since I don't have heat in the car why don't I run the relay board cable through the drivers side heating duct? I can mount the MS box in the drivers side foot well. There are two issues I see with this:

1) The cable must be heavily padded or wrapped to prevent it from banging around the empty tube.

2) The entrance for the heating duct is below the engine tin, possibly exposing the cable to some heat. Perhaps I can thermal wrap it as a safety and shield it from noise.

What do you guys think? My old plan was to run secure the cable to the roll cage, through the rear window and down across the floor. hopefully entering the tunnel at some point. Then mounting the MS in the dash somewhere. However this greatly increases my wiring lengths from about 6' to 10' or so. Comments?
