Hi Guys
In my research i have come across some discussion with regards to the Vr sensor being shielded wire back to the Megasquirt. I have seen the power and ground wires twisted going back to the Edis controller. Is this just standard wire, or is it shielded? If I use the shielded wire do I need to ground the shielding? Any thoughts or pics would appreciated. |
No need to shield power and ground AFAIK, only the PIP and SAW wires which have tiny signals susceptible to EMI.
|
Makes sense now.
|
How are you guys handling the fuel pumps and megasquirt? How is signal handled from megasquirt to existing fuel pump relays?
Where do I make the connection @ existing fuse panel up front? |
The MS uses a ground switch to activate the fuel pump. On the SC, the relay is switched on with a +12V signal so backward of what MS supplies. If the 930 is similar, you can either interpose a new relay to switch a +12V source to the existing fuel pump relays or rewire the existing relays to accept a ground signal. I chose to rewire the OEM fuel pump relay to be compatable with the MS signal.
|
I believe the 930s use a switched ground on the fuel pump relay. Pin 87b on the fuel pump relay. If I run signal from Ms to Pin 87b will this run the pumps?
|
IIRC I took the Fuel pump wire from MS and connected to the overboost wire at the 14 pin connector. I did not alter the factory wiring at all.
|
Excellent. I will give that a try. I am currently trying to address all the issues ahead of time. I have ordered my crank pulley from GSF. I am going draw up a wiring harness, for existing items I plan On keeping, and a harness for new items for mega squirt.
That way I can have the pelican parts members review and critique. |
Billjam has got great skills and has posted some layouts of how a harness could look like. Maybe you can use that.
|
Once you have a clear idea of what wires to tie together from MS to factory, then it's a whole 'nuther project planning to route them to where they will terminate.
Once those are figured, the soldering is the fun part IMO and goes quick. |
Package arrived on Friday. Injector blocks, fuel rails, cross over fuel line, fuel pressure regulator, and a few AN fittings. Plan on ordering Megasquirt 2 this week.
Also received my AC pulley wheel from Albert last week. I ordered both 36-1 and 60-2 wheels, also ordered the focus vr sensor and the distributor plug. http://forums.pelicanparts.com/uploa...1369096457.jpg http://forums.pelicanparts.com/uploa...1369096484.jpg http://forums.pelicanparts.com/uploa...1369096500.jpg http://forums.pelicanparts.com/uploa...1369096558.jpg |
You have the wrong wheel to use with mega squirt it will be 10 degrees off
|
I have both the 36-1 which is mounted on the pulley, and the 60-2 shown on card board. I was thinking of using 60-2 with my current setup Electromotive HPV1.
