it sounds so simple doesnt it!

if you have actually done this, kudos to you, because i could not get it to run like that. trust me, i tried *EVERYTHING* 10 times over.. followed the msnse instrustions for finding the angle exactly, altered them some, tried my own way of figuring it out.. i spent a week trying to get it to work like that, and it just wouldnt. i cant explain why.. i dont remember, i dont think i ever had a solid explaination


what i do know is that i built the thing from scratch, msnse v3 board, relay board, 100% custom wiring harness.. a shit ton of fabrication and assembly and planning, and once i decided to rephase the distributor to where i thought MS would like it most.. the car fired up instantly and had no issues from that point forward.. so i am not a retard and i dont *think* i was doing anything wrong.. its not impossible that i missed something, but damn i dont know what it could have been because i spent so much damn time trying to figure out what the hell was wrong..

the whole reason i didnt just rephase the distributor in the first place was because like you said, i SHOULD have been able to compensate for the rotors position relative to the trigger in megatune.. but i couldnt get it to work that way



so.. if you actually have gotten a 2.2/2.5 running on the stock ignition stuff using only software to set up the timing properly.. please post up the details of how, because id love to know what i missed... i drove myself crazy for a week trying to figure it out.. so frustrating after spending all that time building the ms stuff and rewiring the entire car to have it sitting there not running and not being able to figure out why lol

hey man, just wondering if your writeup is still coming, or where it is if it's done

And wheres that exactly ?

Setting the engine in TDC and checking everything to be in the initial position ...


and then whats your suggestion point at ??... I think its 45° clockwise, am I correct ?

Thanks.

Woot.
Im getting my MS II board fixed by bansheenut and I can start getting ready to install

[Shadow24V]

now if i can get EDIS working ill be ahead of you all! (thats IF mind you....)

[guidsm]

Mine is running great since 3 month on edis ;-)

[donalson]

i may have missed it... but did you just use the stock sensors or move to GM sensors?...

for things like the head lights and such, did you just pigtail the plugs for the new wiring?

also any "final word" on the easiest way to MS with the dizzy?

thanks

I was wounduring how hard it would be to do a megasquirt in my 1992 turbo daytona and what all do i have to get???


thanks mike

Hello all,

My daytona 1992 hybrid is running on MSnS extra with stock coil pickup (fuel only mode) since begin of August. I have some noise on the input pickup that triggers the fuel cutout so I had to remove that to be running more correctly. I use the original ECU for everything (spark, dashboard,..) but I installed my own sensors for the MS and a WB 02.

I am interested in sharing the MSnS setup and parameters (I am abroad right now, I will be at home next monday). I was running at the beginning in alternate/2 squirts and idled decently at 1000RPM with an AFR of about 20 (I was quite proud of). After reading a post on the msextra forum, I decided to start from scratch with a simultaneous/4 squirts as my setup until now was pretty basic and not correctly tuned because of the input noise (athough driveable, I did a 235 kmh top speed running MS). I am running 8 pounds of boost,until I get it properly tuned with that boost pressure and after I replace the fuel pump.

Otherwise,my setup is :
- +40% injectors at 30 psi
- Ford IAT
- Ford CLT
- Innovate WB O2
- GM 3 bar
- stock turbo dis


I would like to use the cam sensor of the neon head as trigger for my fuel. From all what I read so far, only the crank sensor of the neon seems to OK for use. I investigate that further and hope to be able to post positive results on that matter soon :-)


Cheers,

Hey I just finished my MS too

My setup:

GM CLT
GM IAT
Innovative WB LC1
MS I V3
MSnS Extra
+40's at 50psi
MS 4bar
Stock hall efect spark pick up (TBI distributor)


Right now is idling let say normally, the car sounds great, but its too rich (12.5 AFR) ... I need to move more the tables, I think Im learning a lot of this and will be really helpful to share tables and opinions !

Tony.

Follow the instrucctions made by GUIDSM in the page 7

[UnaClocker]

You can use Chrysler's stock intake and coolant temp sensors. Simply swap out the bias resistors (R4 & R7 on the V3 PCB) for 10k resistors when you are assembling the unit.

have any of you guys gotten ms working on the stock ignition system without altering the distributor?


i have my step by step guide thingy halfway done and wouldnt mind actually finishing it sometime soon, because i keep getting people asking about it, but if there is a way to get it working without modifying the phase of the dizzy id like to hear about it so it can be included



when i was building mine, i tried using ideas from guidsm's post.. but it was a bit hard to follow and i think i ended up doing things differently somehow.. its been while since i did it so im a bit rusty on what.. but there definately is no comprehensive info source on getting these cars megasquirted


edis has long been an option, but is just a huge pain in the ass compared to using the stock stuff.. i would have been megasquirted long ago if i had the fab and welding skills/equipment to rig up the trigger wheel



another thing to think about now as well is all of the advances in dcal and the like lately.. its almost not even worth it for the average street car to go with ms since the eprom cal stuff is getting so good now...


for me the decision to go ms was mainly influenced by my long history of electrical pains in the asses on these cars.. the fact that the entire electrical system was going to be new was a huge plus.. no shitty wiring, fusable links, corrosion, weird splices etc.. makes troubleshooting 100x easier.


and yes, for the lights, starter, tach etc i just used the stock bulkhead connector. all of the in dash wiring stays factory stock, all of the underhood wiring is replaced.


its possible to just reuse a lot of the factory stuff, but if you are that cheap/unwilling to run new wiring, you may as well just run dcal.. ladybug.. whatever its called, i forget.. to me most of the incentive to going with a programmable ecu though is the fact that everything is new and confirmed good. no mystery gremlins.

you are missing the point homes..

the orientation of the oil pump gear isnt what i was talking about.. that stays just like stock. what i did is reset the shutter wheel inside the distributor so that at the base ignition angle.. 12 or 14 or whatever degrees, right as the shutter vane is crossing the hep the rotor should be pointed directly at the #1 plug wire... that is not how it is set up from the factory, the factory ecu seems to read the hep from the trailing edge, whereas ms likes it from the leading edge, so there is a huge difference in timing that i could not account for in software

the way it is set up stock is not the ideal way for megasquirt to deal with it. there are means of compensatig for it in the software (that i could not get to function, hence physically altering the dizzy) but ideally, the dizzy should be set up like i did it. it is the most accurate means of firing the spark. the compensation settings use a formula based on when the hep is activated to calculate when the spark should be delievered... a minor difference (and one i would have been fine with im sure assuming i could get it to work) but it exists.



all i know is what i experienced. id like to hear from someone running on the stock ignition that didnt have to rephase the dizzy though, because as far as i know im still the only one to have done this.. and i would freaking still love to know what i missed, if i did miss something.

[Shadow24V]

were you running the MS-I or MS-II? because IIRC you can set ignition triggering/RPM off of leading OR trailing edge. Did you ask on the forums? because there should be a way to use this distributor on MS....

i didnt have much trubble at all configuring MS-II and EDIS on my v6. i cant fabricate well, or weld, but i made up a bracket for the sensor, and i got my neighbor to tack the wheel to the outside of the crank pully in 2 little spots. those welds didnt hold too well at 5K for more than 20-30 seconds, but im taking it to my cousin to REALLY weld it up, completely. other than that, im good to go with it.
