Runs very well actually...

[r34 gtr]

Well I finally got my car running properly, and boy does it ever run properly. Starts instantly, idles perfectly regardless of ambient and engine temperature, revs very very smoothly... When I push in the clutch when I am coming to a stop the revs drop to about 900rpm where it stays, and it doesnt even slightly dip below this (no stupid revs dipping junk). All in all I could not be happier with the megasquirt II. My car runs so much better now than it ever did with the stock engine management, and I dont even have any sort of idle control! (other than msII of course). It is very fast on only 7psi of boost, and under load I am seeing a nice conservative 11.3:1 AFR, with a cruise around 14.1-3:1 (I know it still needs a bit of work, but it runs well enough to brag!). I just want to recommend this system to anyone considering a stand alone, as it beats the hell out of everything else in terms of price and features. Finally I would like to thank The_Chosen_One, aka puma, because without his constant criticism, cynical remarks, and help I dont know if I could have done it. Thanks man!! Megasquirt II FTMFW!

I will post up my .msq file when I have it honed to perfection. Right now I'm still smoothing out the AFR's a little bit and messing with the timing down low to give it a little extra grunt off the line. Also my laptop has no internet connection, but I should have it for you guys this weekend.

congrat thats good to hear. It is probably mentioned in some of your threads but how did you hook up the crank angle sensing part?

also was wiring difficult \ long time? I wired the ca to my s14 which was kind of easy I think so Im thinking about going this route.

thanks

[Bwana]

ZOMG! Tim, you're saying you did something right???

How many units of blood did it cost you?

[ragenasian]

Congrats!!! how many beers did this take

[r34 gtr]

I mounted the sensor in almost exactly the same way as in the megasquirt writeup, but my timing gear is on the middle 'rung' if you will, of the crank pulley so I can still run my factory power steering setup.

The wiring is ridiculously easy, even more so because I bought a pre-made harness from diy autotune and it was all pre-labeled.

Cost me about 3 units of blood, two knuckles, and a broken toe. results not typical, I am an idiot.

Beer wise I probably drank way too much. To the point where it actually took me longer to complete said project. I mean, I bought my msII kit in december.

Now the car runs fantastically well, but it leaks oil from the rear main seal, the steering rack, the power steering pump, and both the front and back seals on the transmission. Its no beauty queen, and its not track legal, but it goes like a scalded cat. I just cant get it to stop leaking oil, whenever I fix one thing, another starts, so I just dont care anymore. I'll fix the transmission when I break the sh*t out of it. Same with the rear main.

[Masterdebater]

who needs to fix oil leaks anyways... when u run a quart low just throw a new quart in!! woo!!

[jt15833]

are there any other methods to hooking up the angle sensor than hacking up the crank pulley? I use all 3 belts.

also i see from ms website that msII looks like processor upgrade for msI? but on vendor sites you can buy complete msII kits for like 255 or msI kits for ~180. im guessing msII is a complete system and successor to msI?

MSII uses a faster processor, and has larger fuel and ignition maps. you really just need to go to megasquirt.info and do some reading. choosing which megasquirt is right for you is up to...well, you.

for crank triggering you can always mount the gear to the front of the pulley. check out how tyrannix has his setup in the megasquirt install writeup, I believe he can still run all his belts.

For all your Trigger Wheel needs

http://trigger-wheels.com/store/index1.html

If you get a thin enough wheel you can have it mounted on the rear pulley or somehow attached in the front.

[The_Chosen_One]

MMM this is what I want.





Whats that a extra plug that extra plug makes it 100 times easier to add crap like boost control, nitrous etc etc yada yada. Mmmm all surface mounted I'm soooo getting that soon.

My friend is building a TT Chevy 350 in a Rat Rod and is using MS II w/a custom wheel he made (He owns a fab shop). If there was enough interest, I could have him make us CA guys something that would fit on the back of the crank pully so that you'd have all of your belts.

[jt15833]

how would it mount to the crank pulley? weld? reverse clamp or something?

[r34 gtr]

You could weld it on, but I would be worried you would mis balance the pulley itself in the process. The problem with mounting a cog to the back of the pulley is that the CA uses that pesky metal arrow thing for timing purposes. If you can live without it (shouldnt be hard to make some marks and go about it that way) then it shouldnt be a problem. Just remember that there isnt a whole lot of room back there.

Mother*@$#er!! My engine mount heat shield thingy rubbed through my oil return hose and its sprayed oil everywhere down there. Totally weak, now I have to go to auto zone for some hose, jack it up, crawl under it and work in the narrowest space on my car with a f*in crowbar so it doesnt happen again. On the bright side the oil was so clean I didnt notice what it was at first!

Seems were getting the same problems Tim, instead of the heatshield eating my hose it was the Steering Shaft knuckle. I was driving down the road and noticed my passenger seat area started smoking LOL.

[r34 gtr]

Wow, sounds like a blast! Mine doesnt smoke or anything, but it seems to spray at a good pressure. I think I'm just going to not worry about it until the weekend. +1 for the campus bus stop 10 feet from my house.

[The_Chosen_One]

I fixed it with a 45* 5/8 Barb fitting.

[r34 gtr]

Mine will require some levering so it doesnt happen again. Not looking forward to it, but hey, what can ya do. Its not like its anyone else's fault that it needs fixing.

[The_Chosen_One]

you could rub my balls in your mouth.

are u hi or hammered? u might get ur balls ground on by some teeth or something.

funny u should say that, watch this vid tim I think you'll like it.

Yea I dont drink or get high its not my style. I just **** around like that

[r34 gtr]

Seen it, sorry. It is possibly the gayest thing ever though.

[jt15833]

i saw some writeup about using people with DSM's using their stock CAS for megasquirt. is there any possibility to this with ca18det?

[The_Chosen_One]

i saw some writeup about using people with DSM's using their stock CAS for megasquirt. is there any possibility to this with ca18det?

If you want to use the CAS you'll need to switch a Autronic disc to replace the disc inside the cas. The disc inside the CAS is weird you can still get the oem disc to work but requires more effort, the Autronic disc will make it easier.



http://www.autronic.com/page_f...s.htm

You could also wait for the router board which will read all OEM discs and include Sequential Ignition and Injection.

[jt15833]

chosen i am two steps behind you as i JUSt read your reply on the write up and i just saw those discs on the megasquirtefi site. i wont be doing this until early next year so i may wait around for that board.

the autotronic discs will work with msI and msII right? i read it may be easier with msI because of documentation but I really want to go with msII for the new technology aspect.

also it seems like it may be a lot of work (or waiting) to hook up my coil on plugs. I've read that the ford spark system is reliable and preferred hookup. I can use the autotronic wheel and the ford ignition ya? Is all that is necessary for the ignition expensive?

[r34 gtr]

I dont think you can use the stock CAS with EDIS, because it is its own system, separate from megasquirt. It has its own control unit and everything. If you use EDIS for ignition you will need to mount the VR sensor and trigger wheel.

[Dattebayo]

Sequential ignition? Cool. Are they going to have a harness for that made up too? Anything that keeps me from wiring I am up for...

[jt15833]

hrm i thought with the autotronic wheel it would take care of crank positioning and with that you could use edis. maybe not. sorry for thread jacking thanks for replies.

The disc will work with whatever processor now, before it was mainly MSI but that was because of the MSnExtra code. The creator of the MSnExtra code has now been releasing codes for MSIInExtra so you get all the good stuff with MSI but with more power and extra features. The MSIInExtra code has 16x16 maps and bunch of cool **** that I havent messed with.

The MS board has 1 ignitor built in called the VB921, if you want to use COP u add 3 more of those mini ignitors. Heres a pic of what that may look like.



The FORD EDIS is extremly reliable, I just read a report on several coil systems that have been tested.

Quote »So far, out of the very few ignition coils I have measured the Ford EDIS and the Mitsubishi wasted spark ones yield the most energy storage capability, secondary spark current, and burn time. The worst was the old Standard Products UC12 universal for breaker point ignitions, in terms of primary charge time and secondary current. [/quote]The FORD ignition LOVES BOOST. Theirs quite a bit of people using it in the 1000+WHP club. A guy by the name of Parish who has a Twin Turbo LS1 in his Silverado uses it.



For the Autronic disc you could use the that and with the FORD Coilpack sure, but no on the EDIS reason being is because well the FORD EDIS is a ignition system, it does what the CAS does just differently. HOWEVER when the Router board comes out you can use the FORD VR sensor and crank wheel AND the Nissan CAS. The Ford VR sensor reads the crank position and the CAS will tell EXACTLY when to fire the cylinders and u wont need the Autronic wheel.

As for the FORD EDIS being expensive, I got mine for $30 and paid $23 for NEW Plug Wires. The $30 was for the coilpack and the VR sensor, Wheel, Module was free with coilpack. If you want a new coilpack Summit sells them for $50 made by Accel. Also you wanna know how good the coilpack is? Put it this way after almost 20years FORD is still using the same coilpack on their new cars.
