I am running fuel and spark, sooo: 36-1 crank trigger drives all of my stuff. Coil packs running wastespark and batch fire on the injectors.

I'll have pictures of it once I redo that. Right now its just a big ugly thing on the front of my dampner.

 

Alright, cant get it to start on MS, I'm not seeing any rpm in megatune with the input from my MSD box. Gotta figure that out...

 

I tuned and built an MS1 v3.0 with msns-extra code for my uncles TBI 305 It uses 2 low imp. injectors, I just used the PWM values that the manual gave and it works good.

The extra code is a good thing even if you're not going to use spark control, it gives 12x12 tables and a ton of other options.

I'm going to be running MS1 extra on my 300zx when I put the 'big' turbo on, if I ever get the motor together....


How do you have it hooked up? Here is the manual page for using an MSD.

 

The thing I find aggravating about MS is that anyone that knows how to apply it to their LT1, won't tell you any meaningful details about how to do it. I've written dozens of write-ups on how to do many things on our 4th Gens for public consumption on many Fbody forums so "I" have contributed. I've even tuned other people’s cars with LT1 Edit for free and helped install all kinds of things (Torque Converters, cams, shocks, springs, headers, etc) so I help my brethren. But approach any of these guys diplomatically as can be done, even offering to pay, and either you get ignored completely or such oblique answers such as "Yes", "No", "I did it myself", etc.

The MS forum is so unfocused. The people out there that have installed it, have installed it on every internal combustion motor I've ever heard of and THEY show pictures, details, answer questions, etc. But dare approach any of those guys that have made it work on an LT1 and you get near nothing (At least nothing in the context that you could go out there and install it in a step by step fashion).

I have the "MS I" and "MS II" and purchased the MS specific wiring harness that has the wiring destinations imprinted on the wire ends. I've read and read the MS forums but it's extremely difficult to weed thru the thousands (if not millions) of forum traffic trying to find something germane to the LT1 installation.

At the end of the day, I think the sales of these devices are not market driven. That is, they don't care how many they sell so there's no pressure to increase it's appeal. And the guys that have figured it out, unlike the majority of the other guys engines MS has been applied to, don't want to share or, more benignly, just don't have the time/patience to create a write up on how to install one and get it running in a step by step manner.

 

tell you what.. you buy me a ms2 and i will install it on my lt1 and supply you with a complete write up and schematic....

 

That's for MSII, I have MSI on a 2.2 board, you should be able to connect the tach output directly to pin 24, which ppl told me works, except it doesnt on my car.

 

Thanks but I already tried that with a Vortec and the dude never wrote the document. Fool me once...

 

Ok I got it running, must have been a loose connection or something. Just gave it another shot cranking and had 100rpm, took a few tries then just fired up. Then idled perfect, doing some tuning today.

 

Nice, I really wish I would've kept my megasquirt.

I'm sure I'll be going to it this winter though.

 

It lives on through me

 

It looks like you can use the low-res signal from the opti as a trigger.

Yup, you're right. Good to here that it's working.

 

On the noted link, notice that the posts stop abruptly on 12/2006 and without resolution. That's the common path. People get to point 'x' with the integration of the Opti and MS then they either punt or die I guess. They never go to the point of saying "It works with the opti alone!" or "fugetaboutit". Some have used the 96/97 crank position sensor but that leaves out the earlier LT1's and those of us that have switched to a double roller timing set(no room for the crank position sensor).

 

I still think the opti is doable, but I don't know of any proof, and honestly once you go this far why the hell would you want to keep it? You have other options now.

Good point on the double roller, I considered that path but never thought about it not fitting.... or will it? The only 96 I have done I got rid of the sensor just because...

I don't have any secrets, but I do have a slow *** car that acts up day to day. I would call it reliable at this point, but as far as making power or being done its far from that.

I see 3 options:
edis8
drill the intake and run a dual synch distributor
obdII crank sensor and use the opti as the distributor... eww still using the opti in a way

 

I think the optical sensor portion of the optispark is fine and trouble free (That said, don't ever wash the motor and get the Opti wet!). It's the high voltage portion of the design(cap and rotor essentially) that tends to fail. My original '96 opti worked great from new (96) until 2005 (when it was stolen at a Houston Speed shop where I'd dropped off the car for some motor work). The thing that bugs me is that obviously TurboBob, who created Voltblaster, LTCC and other amazing electronic gizmos for our cars, can intercept the signals from the opti by merely intersecting a male/female combo plug at the point where the stock opti harness snaps onto the main harness. His LTCC therefore knows when number 1, number 2, etc plugs are firing. It seems all it would take is for Bob to extend the technology of the LTCC a bit by providing a simple box with a "D" plug on the side that interfaced with the Opti harness the very same way and use THAT to give the MS/MSII the pulsetrain to fire the MS.

 

My take on the opti is I have had the high voltage fail about 60% of the time and the sensor @ 40%. That will vary for everyone, but I have changed a lot of them on my car and others too. The thing is just to sensitive.
