my brain hurts. is it times for ARTs pimp my crib yet?

 

i updated my sig for tony as i'm as confused as wade with a screwdriver making his car idle.

 

HAHAHAH its not a screw driver... its a small allen head to adjust the throttle stop, not that other adj. point. That one with the screw head wont open enough to idle my car alone. The damn throttle plate has to be opened some! I <3 autronic!

 

My rotor, coil and cas went out on me so I picked this up. Going to try and find time to install it next week.

 

i got a good deal from speeddreamz when he sold his, so i bought it and converted it to obd1.



mounted the ignitor/coil where ac plug was on firewall

 

subscribed...debating on this unit...any1 care to help me out some...my car like 4th gear pulls after driving it for a few hours around town...seems like i am miss firing as if i am hittin a rev limiter ...5th gear pulls usually smooth you guys think the msd pro distributor would help out awhile back my ignitor went out...it was replaced with an OEM one holding up thus far

i don't mean to thread jack...

 

i havent seen any issues with the signal up to about 9500 rpms, i havent done anything that revs higher w/that dizzy, so ic ant really comment..

msd has an obd2-obd1 distributor jumper harness avalible, i think its about 20 bux.

that's nice, as the pins in MSD unit don't plug into the honda plugs, i had to resoldier all the wires.

 

summitracing has an instant rebate on all msd products does anyone have the part number msd ignitor unit...i just want to make sure before i order from summit

 

MSD-6305 is the summit part number.... don't forget the coil too.

 

These are only compatible with GSRs and other VTEC engines, correct?

Any non VTEC love?

 

Hey Tony1, I've checked the signals out of the sensor wires like you've mentioned. It produces no voltage if I manually spin the distributor regardless of how fast I turned it...lol. In addition of what JDogg said about the cleaner signals, I also noticed that my engine starts up right away with the crank-cam synchronizing pretty much immediately. Car runs great all the way to 9200RPM.

I don't think that any ECU's would use the raw sine-wave like signal created by mag sensor, but instead it uses an internal reluctor adapter to convert it into a digital signal. Probably the MSD unit already filtered the signal to something that the stock Honda ECU expects.

One of the reason why I went with the MSD is how they purposely designed the rotor terminal spacing to be much wider than stock. In several cases I've seen high revving Hondas with strong aftermarket ignition and factory distributor that would spark scatter (spark arcing between rotor terminals) and do all sorts of funky things. Seen it a few times with the all motor guys revving to 9.5k and I also experienced it myself when I was all motor with MSD 6AL. My current redline is 9200RPM, so for me, it was either COP, or a nice aftermarket unit because I wanted to move away from the stock dizzy.

Yeah, pretty much the only thing left to discover is longevity... We'll see how long the ignition module lasts, etc.. But most of the Pro Billet dizzy's for the V8 didn't have many issues with long term reliability so I am fond of that. It's a pretty simple part, so let's hope it doesn't crap out like the DIS-4's

Another good design is the plug wire retaining bracket... I seriously had enough of the plug wires popping out of the distributor cap constantly. Looks like MSD had that problem fixed

I also give it a small bead of gasket sealant between the cap and the dizzy... Although the guts of the distributor are fully sealed (sensors, wiring, etc..) with only the rotor exposed, I'd still rather seal it up.

 

I've heard about spark crossfire on small caps, but never seen it happen. I run all my race cars to at least 10,500, and both mine and art's have oem distributors for spark.

Is there any way you could put a scope on the output wires, i still don't see how the stock ecu could accept a square wave signal w/o changing anything inside.

 

Tony, what the diffrence between HVC and Crane coil?

Do u have any pics of M&W installed?

I will be calling Art monday to order mine.

 

If you search for pics of the integra i'm racing, you'll see pics of the motec cdi box in the engine bay (it's a rebadged M&W Pro 10). I'm honestly not sure the differences between those 2 coils, i'm just going by what M&W recommends for a coil.


Anybody have any close up pics of what's inside the MSD dist.?

 

I was looking for how M&W gets rid of the factory ignitor. Does it have one inside the box?

Haha, no scope to my avail right now, and I don't know anyone who can lend me one... Seems like MSD has their tricks in making this work. When there was no power to the MSD distributor, there was zero voltage. Once I gave it ignition power, there was a voltage signal.

Seems like spark scatter is more for the all motor folks because I never heard issues alike inside this forum either... Larry @ ENDYN once talked about it and has to do a lot to do with high temperatures. This would most likely be more common for the roadracing folks from endurance racing, etc... I once had this problem when I was all motor, and a quick fix was drilling vent holes on the cap which helped the problem a bit. Although I am boosted right now, I do take part in many cruises and meets; during the "perfect moment", I would be racing the engine for 15-30 mins non-stop just like what I used to do when I was all motor as well. A boosted engine is less forgiving, and if it ever does spark scatter, it could lead to some detrimental damage. Basically I am trying to eliminate any potential problems that I know of.

I didn't want to take apart the distributor.. Once I took out the rotor, the unit has a few bolts inside and looks like everything is contained inside the housing. To take it apart, I was afraid it would be irreversible; plus there isn't anyone I could turn to for help if I ever busted something or needed replacement hardware. Maybe we should alert one of the MSD tech guys that lurks here on Honda-tech to give us an insight on the trigger sensors

 

There was an MSD guy on here a while back, it would be great if he could shed some light on the situation!

 

Im sure you can get the MSD Dizzy to work the the MW Pro-10 and a Crane PS9 Coil...

= Da H0tn3ss

 

tony i will try to get some pics of the inside of my msd dizzy tomarrow its to late to go searching for my cam right now and a screwdriver haha

 

this is very interesting. i might be running this setup.

thanks for the part number

 

I thought the Hall Effect sensor still uses A magnet just on the wheel side and the power to the actual sensor is just to amplify that signal that it produces? They also sell Frequency to Voltage Converters, so this is how MSD probably does it and by it being amplified it produces A stronger cleaner signal that doesn't weaken and fall of at higher rpm's... I maybe wrong but I have been doing some research on this to see how they did it also because I want to modify one of these dist. for my H22 and it was either cop or this dist. and I did want any issue's with misfires because I plan to rev to 10,500 or 11k and it seems to be A pretty solid dist. from what I've read..

 

so i dont need to change my fast ems to hall effect because it reads like a stock dizzy?

he was a new guy at msd... he got fired within a few weeks.
