66 square going MS

[supaninja]

looks good ninja.

So picked up a uni atv air filter because I couldnt get the stock one to fit, I'll find a way to make it work one day. Took the square out to get gas and autotuned along the way. Got home and let my wife (the owner of the square) take it for the first post MS testdrive. She was ecstatic! "Thats the smoothest this car has ever driven!" was the response once she got back home. There is still some tweaking needed though. I need to learn more about setting up the off throttle slowdown setting. Right now when you take your foot off the gas it doesnt really slow down but kinda cruises to a slower pace. Also need to play with the cranking and warmup settings. Did a minor adjustment when it started up today. Found out I was to rich for its liking on start. I attempted to adjust as it was warming up, but probably not supposed to be done that way. Guess I'll find out tomorrow.

Thats the stuff

Congratulations raggdout63!!!
You get one or maybe 2 shots a day doing the warmups.
Until you get it nailed, it's better to err on the rich side, the flood clear mode is your friend.

I forget, Ms1/Ms2? What version FW?

Munch---My ratsnests are under the back seat and now in the engine compartment, the cover was for the rest of the junk that can accumulate in the storage area of a squareback I'll probably run a roll-up windowshade unless I can find something decent RSN.

I ran the wiring through flex conduit... It was neat before I went all postal doing the LS2 coils.

Pile I'm running MS1 extra. I doubt I'll really get to play with the colder settings much, especially since we are hitting summer and I live in Las Vegas. I will only be able to get down to possibly the 60* range for the next several months.
Currently I'm running with a 009 but I'm not a fan of it, and need to find a better setup. I'm sure I will end up doing spark control somehow, but just not sure yet. I will probably leave that for the end of the year. Trans needs to get pulled and rebuilt, and has never been out of the car before. I'll probably look at spark control at that time.

Mario if you see this, the fuel filter I got in your kit is that a pre or post pump filter? If its post is what is everyone running for a prepump filter?

OK so I cruised down the freeway several miles down the freeway today. After 8 miles or so I got off the freeway and a couple of hiccups as I was heading towards the offramp. I brushed it off as nothing. Then later today I was cruising down a boulevard and it bucked/surged several times. I didnt have my laptop hooked up at the time so no datalog.

Any thoughts other than try to replicate while datalogging? thanks

[supaninja]

Thats hard telling: fuel pressure, vacuum leak, clogged injector...

Just a thought, but are your gas tank vents clear, and are the vent hoses in good shape? I had a similar problem after converting my 69 bug to Subaru power (EFI). After the car ran for a while, it would start to stumble intermittently. I ended up finding that the vent fitting on my gas tank was partially clogged with gunk. Once I cleared it out, the problem went away. Did you clean out the tank before starting this project? Maybe the fuel system pulled some gunk from the tank through, and you had a temporary drop in fuel pressure?

I'm in Vegas as well. Is the square going to make it to First Friday at Findlay next week? I've seen a bunch of Megasquirt projects on the web, but never in person.

Nick.... you're bug is sweet bro love the suby conversion. The square will make it out next month.

As for the tank it was blasted and thoroughly cleaned by the PO. Before this project I did full empty it and nothing but bare metal in there. The vent hose is in good shape, but i never checked the actual vent, will do this evening.

[supaninja]

You guys got me all paranoid so I checked mine...blow into, DON"T SUCK. Lesson learned, derr herp herp.

Any new updates, mines running like an absolute boss right now.

[raggdout63]

ninja you crack me up at times bro. I havent driven it since it hiccuped the other day, but tonight is the monthly get together. Thats not the only time we drive it, but we've just been busy lately. Ill report more, probably tomorrow.

Note to anyone using the UNI ATV filter with the stock T4 size TB or carb neck---
The urethane neck will apparently crack if you cinch it down more than a small amount.
I pulled mine to clean it @12K, the outer was filthy after driving down some dusty dirt roads, the inner didn't even make the dawn/hot water mix change color, so I guess the outer filter was doing it's job.

I shoo-goo'd mine back together, should hold, but I will be installing a filler/extension to fill the 2.25" neck out to prevent further issues.

Ok so here is the safety notice along with God was watching over me and my son. A couple weeks ago I tried fitting a stock FI oil bath filter and loosened up some fuel lines. All were in place and hose clamps tightened down, except the one leaving the fpr back to the tank. Apparently I, being in a hurry, never tightened that hose clamp back up. I had driven it probably 40-50 miles this way and only discovered it yesterday when I had it idling in the driveway and noticed it pouring out under the car. So I tightened it back up and no damage done other than loss of fuel.
Last night was our monthly las Vegas get together at the local Vw dealership and I was able to show off the work that went into it to quite a few people and tried to sway many to go this route over carbs. I hope to start seeing converts.
Mooseman good meeting you yesterday too, and I like the Suby swap you've got.
Pile. What are you using for an outer filter? I've only got the foam and I need to oil it according to the uni info sheet I got with the filter, but I don't want to oil it.

[Piledriver]

Use the oil for foam filters, its really tacky, the UNI stuff works well (of course)
The K&N oil is too thin, might as well use ATF.

In a pinch you can use std motor oil or even chainsaw bar oil...(pretty close and cheap)
Expect to have to do it more often using motor oil, like monthly.
The Uni stuff sticks around awhile and doesn't drip out all over your motor.

The shoo-goo didn't stick to the urethane at all, but the inner neck is a press fit over the TB.
I've been wanting to add a proper ram tube anyway in order to pull the tq pk down from ~3900.., so I'll be `nigineerin sumthin.

My filter came with the red outer pre-filter on it.
The "fine" inner filter is gray.

You need to add a filler/spacer around the TB if you have the same filter I did to avoid the tearing issue.
A few rings of inner tube stretched over the TB ought to work.

I've only got the foam and I need to oil it according to the uni info sheet I got with the filter, but I don't want to oil it.

You need to oil the filter, as it won't work at all without oil. The UNI oil is very tacky and easy to use, and it doesn't drip all over everything like K&N oil. You can buy the UNI stuff in spray cans from any motorcycle shop (I use Carter Powersports on Decatur). Lightly oil it, just enough to coat the whole thing. You don't have to drown it.

If you have a gap between the filter size and the throttle body size, you can wrap the throttle body neck a few times with electrical tape to 'build up' the throttle body neck size. I had to do this on my MAF sensor and throttle body, and it works well. Just make sure to use good quality 3M electrical tape!

So we towed the Square down to southern CA for the VW Classic weekend. I wasnt about to torture my young kids driving from Las Vegas to So Cal in the square and causing us all to get heat exhaustion. I arrived at the host hotel around 1015 friday night, we missed nicks burgers... oh well. I unloaded the square for the weekend. Saturday we drove it all over, did our Las Vegas VW Club Pacific Coast Highway cruise. Man that was a blast!! The weather was perfect and tons of other awesome cars and great sites to see. Sunday my wife and kids cruised it over to the Classic in Irvine while I packed up the truck and headed over shortly after them. All in all it was a great weekend. The square ran flawless, although I do still need to work on the cold start, but its not a major issue. My wife is happy that her square is on the road and running well. I still want to tinker with it but need to leave it alone and start on my bus. Which will also be megasquirted.

[Mooosman]

Good to see you at OCTO on Saturday. I didn't spot the square on Sunday, though? Maybe I missed a row; seemed like there were more cars this year.

I'm definitely going to bring my 69 to the Classic next year. I didn't get the brake and suspension rebuild done in time for this year...

See you at FFF!
