Ffeog1 Posted April 29, 2014 Author Report Share Posted April 29, 2014 I've been looking and can't get a straight answer. Quote Link to comment Share on other sites More sharing options...
StarquestRescue Posted April 29, 2014 Report Share Posted April 29, 2014 The drivers side main harness stays. The pass side engine harness can be removed. You will need to add a couple of wires that are not in the MS harness. One for oil pressure, and one for the dash temp gauge. I can't remember what else.

ucw458 Posted April 29, 2014 Report Share Posted April 29, 2014 One for oil pressure, and one for the dash temp gauge. I can't remember what else. The starter wire in the engine harness would be pretty important. Quote Link to comment Share on other sites More sharing options...
importwarrior Posted April 29, 2014 Report Share Posted April 29, 2014 yes that's correct. I marked those wires.oil pressure.temp gaugestarter wire mark those or put a zip tie on them to make a note to save them.then remove the harness and unwrap it so those 3 wires can either be reused (what I did) or you know what and where they go and replace them.

ucw458 Posted April 29, 2014 Report Share Posted April 29, 2014 Also if you are keeping AC you need the compressor clutch wire and the AC switch wire on the thermostat housing. The one on the T-stat housing can just be grounded anywhere you like. Quote Link to comment Share on other sites More sharing options...
slowquest Posted April 29, 2014 Report Share Posted April 29, 2014 The starter wire in the engine harness would be pretty important. That wire, next to the battery is simply taped up inside the engine harness, very easily taken out. It's only a couple inches long. The b38 connector just needs oil pressure and coolant temp hooked up. Also a good place to pick up power for ms. Quote Link to comment Share on other sites More sharing options...
Ffeog1 Posted May 10, 2014 Author Report Share Posted May 10, 2014 Will megasquart be able to use stock distributor to get crank position? Quote Link to comment Share on other sites More sharing options...
psu_Crash Posted May 10, 2014 Report Share Posted May 10, 2014 The stock distributor provides a variable reluctance signal that can work well for a tach input. If you want full standalone it works for spark too if you keep the distributor. It won't work for a sequential setup as there is no TDC signal.

Ffeog1 Posted May 12, 2014 Author Report Share Posted May 12, 2014 So adding a crank position sensor would be the easiest or could I use a tack adapter for megasquart Quote Link to comment Share on other sites More sharing options...
ucw458 Posted May 12, 2014 Report Share Posted May 12, 2014 The easiest would be to get a dizzy from a 4G64. They require a 1/4" spacer and light fabbing but will bolt into a G54B. The benefit is that dizzy has cas/cam. Meaning it outputs a crank and cam position signal. With that you can run sequential injection and individual coils.

psu_Crash Posted May 12, 2014 Report Share Posted May 12, 2014 (edited) I run what ucw is speaking of and I have zero complaints. Pretty sure I made a thread about it in the MPI sectionEdit: http://www.starquestclub.com/forum/index.php?showtopic=113572&hl=psu_crash&do=findComment&comment=1104359 Edited May 12, 2014 by psu_Crash Quote Link to comment Share on other sites More sharing options...
Ffeog1 Posted October 1, 2014 Author Report Share Posted October 1, 2014 Okay so heres where im at. i got a VR sensor on my pully and a VR conditioner for megasquirt 2 v2.2. so if i run the stock distributor to control spark with msd6al is the vr sensor going to just control Fuel? i guess im stuck because i cant seem to get spark when i have the coil hooked up to battery just to test. Any ideas? Quote Link to comment Share on other sites More sharing options...
psu_Crash Posted October 1, 2014 Report Share Posted October 1, 2014 If I understand you correctly than yes. The MS install will be fuel only if you are leaving the stock distributor intact and using the MSD box. All MS needs to see from the crack sensor is a tach input.If all of the stock ignition components are still there you should have spark. Is your MSD connected like this?http://www.starquestclub.com/forum/index.php?showtopic=58296 Quote Link to comment Share on other sites More sharing options...
Ffeog1 Posted October 2, 2014 Author Report Share Posted October 2, 2014 No I have none of the stock harness. Would it be easier to cut my stock harness up and put back together? I feel like the board I have (v2.2) isn't really good so if I could you stock for spark with help of msd that would be fine. Or maybe edis? I'm not sure eat this point. I know you said before you recommend another distributer. If I get that can I just throw the vr crap away and set my ms up straight to it?

ucw458 Posted October 2, 2014 Report Share Posted October 2, 2014 Your setup isn't bad. You can run batch fire on it and have a good running car. Quote Link to comment Share on other sites More sharing options...
scott87star Posted October 2, 2014 Report Share Posted October 2, 2014 If it were me I'd keep the VR stuff, lock the dizzy advances and run full ignition control, let MS control the MSD. Crank trigger (VR stuff on the pulley) is the best. If you want to email me your tune file for a check over PM me. Quote Link to comment Share on other sites More sharing options...

Or do you need me to set one up and send to you for input? Also I'm not quite sure my vr condioner is working properly. Quote Link to comment Share on other sites More sharing options...
