Excellent work taking the rebuild to a higher level of quality. It is coming together nicely.

I am presently designing a turbo engine based on a 3.2. Engine is back from machine shop.

I am rebuilding RUF 3.4 BTR out of a Gemballa Version III. RUF supplied this motor with 5 Speed etc in 84 to Gemballa. The engine has about 20K Miles, but was sitting for a while. I just spoke with RUF in Germany and they recommend 993 Turbo studs.

Just in case anyone missed it, I have become a recent convert to using steel studs instead of the OEM snap happy alloy.

Take a look at :

This is why I do not recommend 993 studs - they let heads lift with 1 bar of boost.

Oh man, I have nothing intelligent or knowledgable to say about motors. But I had to comment that those virtual gauges are absolutely OFF THE CHARTS! Man, if you can get an LCD dashboard working that ties in to your mp3's cranking through the stereo, then that would be the craziest, slickest DIY project I've ever seen on this BBS...http://www.pelicanparts.com/support/smileys/pray.gif

LOL, thank you for the compliment Janus but I have a long way to go to completion on many fronts. Once I get my current employment woes straightned out I will be back on track but for now its time to focus on keeping money in the bank instead of blowing it all on my 930, for now at least.

Don,

Thank you, I will follow your advice. ARP has a backlog, but there are some on ebay. I will get a set right away.
I was following your progress and must say absolutely stunning what you did. As I mentioned I am rebuilding my 3.4BTR, but I am going to use the colors you used. Have fun and thanks again,

Regards,
Michael

Excellent Thread! Great Ideas Too! I'm in the tear down phase
 

Wonderful Thread! Got some decent tips and will post my progess on my 82 930!http://forums.pelicanparts.com/uploa...1120101583.jpg http://forums.pelicanparts.com/uploa...1120101627.jpg http://forums.pelicanparts.com/uploa...1120101723.jpg http://forums.pelicanparts.com/uploa...1120101806.jpg

350hp930,
Best thread on Pelican. Quality, content, tone, persistence all exceed my expectations of a tech web board thread, by a long way. Thanks!!

Thank you for the compliment. I'm just a little sad that my project is once again on hiatus until I settle into my new job.

I need to check the thread views on some of the other boards but this thread is certainly becoming one of the most viewed on the entire PPBBS.

Thanks for all the info and pics. VERY helpful.

On vacation so I have somwhat delayed responses. Re the MS II it is typical of ALL such systems in its stage of development. Boils down to "You get what you pay for". After you have done countless developments as I have you eventually get to the point you can look at a similar product and know where its at. Same for any professional in most any profession. If you don't beleive that you haven't lived long enough yet. Just look at the pros and what they use. Its not just money, its whats best, afterall thats all they care about. That and winning. If something was JUST AS GOOD at less money they would use it. But they don't, therefore there must be something of value in the big buck systems. And there is, its more refined, capable, and reliable. To get the same overall performance out of a MS II you have to put in the development time (MONEY) to make it so.

Here we go again.

I'll post my question second time:

So, how many aftermarket EFI systems have you installed/mapped/tuned and what kind of problems did you run into?? And yes please, go technical on me ;)

Frankly, I believe you never ever installed any and just vent your personal opinions based on what you read on the internet. You are clogging otherwise very interesting/educative thread with your ramblings.

hahahaha!

There goes the tone....

Always a blast to read this thread.

Those digital displays are similar to the ones in the T-38C that I fly at work. I'll see if I can find a picture.

When writing the code to generate the gauges I did my best to mimick the style of the factory VDO gauges. It should look pretty good in full screen mode with several of them clustered together.

Once I get settled into the new job and start saving up some money again it will be time to put my giant automotive jigsaw puzzle back together.

You could also wire some buttons up on either side of the screen to allow you to select options or to cycle the visable guages or to display peak readings etc.
They could act like keyboard keys.

For even better than that I could upgrade to a touch screen LCD and program in some soft touch functionality. I picked up my 14" screen on sale for right around $200 so I have skipped the additional functionality for the sake of keeping costs down. Touch screen LCD panels arn't cheap but a small trackball is.

Yeah, cost is why i didn't sugest one of those.. i was thinking that you could get some nice buttons and wire them to a stripped out old keyboard and then arrange them as 4 buttons down each side (like on an ATM).
Then display little icons on the screen next to each active button to indicate what it does.
Maybe you could wire one button to the crtl and alt and del keys for easy re-booting for when windows locks up.. just kidding (maybe).
;)

a little thumb mouse!

When do you think you will be finished??

This is why I didn't start a thread like this. I figured everyone would give me crap for taking forever. :D

My plan is to wait until I have a month to go and then pull out 18 months worth a pictures and act like I hauled butt through it. Not really, I haven't taken enough pics.

Don, how's your re-rebuild going?

Just dropped the pistons, heads and case at JB Racing today. I'll have all the parts back in about 3 weeks. I should have the EBS parts in a couple of days. The weather sucks here in Atlanta (hot plus extreme humidity - temp=hum), so I am not loosing out too much (no AC).

When are you going to be done?? ;)

JB in Orlando?

Taveres, actually. Right next to Alex Job Racing....

Thanks for posting your rebuild. Do you work for Dave White

No - I am a transportation consultant in Atlanta

I'm shooting for 3 months, but my original plan was 3 months and that was 13 months ago. I procrastinate and get side tracked way too much. I've got the engine together minus shroud, fan, and sheet metal. I've got the rear suspension rebuilt, the new fuel lines run, the engine compartment and oil tank painted, and I'm finishing up the rear brakes. I still have to buy and set up the EFI and build the intercooler.

I guess I'm a madman when I start assembling an engine. Normally I try to get all of my parts sitting there ready to go, then we start assembling. Last time we did it in this order:
1. 1st night - measured
2. 2nd night - assembled the case
3. 3rd night - pistons/cylinders
4. 1 full day bolting on heads, installing cam housings/rockers
5. 1 night to set the cams and close it all up
normally 5 or 6 hours after that we have it ready to go in the car with the tranny mated to it.

So we've got it down to a 4 days worth process if you have everything sitting there waiting cleaned and ready to go. With 2 sets of hands moving on the car at some points along the way, we did the last rebuild in 28 hours over 4 days and had it back in the car and running on the 5th day!

We must be crazy, or either we've gotten it down to a process....

Brian

brian you are hardcore

Or voice recognition???

DRIVER: "Turbo!"
930: "Yes, Tony, what can I do for you?"
DRIVER: "Show me my current cylinder head temperature."
930: "Yes, Tony, anything you say."
DRIVER: "Looks like my temps are well within spec and have some available head room. Turbo, raise the current boost another .1 bar."
930: "Yes, Tony, boost is now .1 bar higher. Would you like to see a menu of recording options for your Tivo tonight or perhaps an update on the waiting times for all of your favorite restaurants within a five mile radius?"

SmileWavy

LOL, I dunno if the voice recognition software out there could ever work with all the background noise the 930 will generate. ;)

Dave White tried to recruit me to be his engine and tranny guy back when I was working as a machinist but I ended up turning him down.

It was tempting but I realized that my future lied elsewhere.

For what it's worth, here is dyno paper for Mercedes 2.5 16v that has been "liberated" from CIS and converted to EFI together with Forde EDIS ignition. Everything else was kept the same...even CIS housing was kept, but without airflow flapper.

Let the world know what you think after you finish. Re the buy vs build or buy a known system vs the MS system. I have already stated my position and the likely result.

Yeah, but you still haven't answered Beepbeep's question... :rolleyes:

ianc

You probably missed it, but there is a Pelican member (TBitz) who developed and currently sells a MegaSquirt based CIS-to-EFI kit for SC cars. Installed user base is growing steadily and users post their expiriences on 911 Tech forum. So long, I haven't seen any negative opinions.

Some of them dynoed cars for and after as well.

While MS is somewhat finicky to tune, there is lot's of help online and once tuned, it's surprizingly stable.

Considering knowledge that 350HP930 displayed troughout this thread, I'm quite confident that installation and programming of MS won't be biggest obstacle in his project.

Well the latest 2 were Electromotive systems. They work well. Others I have long forgotten but there were several and they were very unreliable.

My point is and it fits almost all electronic things of which I am very very familiar as I have devoted my life to electronics, I live breathe. sleep with, dream about, live on electronics. I have a MSEE and enough experience for several PHDs in electronics. I make a huge income from electronics, in fact all of my income. ALL electronic devices go thru the same development stages, ALL of them. The stages are all almost identical. The ammount of work to finish the next stage are almost all the same. That said I know which stage the MS systems are at and consequently the ammount of work required to complete the next stage. If you are not going to make a living selling the stuff, there is no justification for puitting in the ammount of work required to make a MS system work properly at this time, unless your time is worthless. If you put several hundered hours into something that others will benefit from and you will be compensated for, its one thing, but to do so for one system, just for you, and most of the work will most likely be duplicated by others and one of them will eventually sell it to anyone, well its just not worth it. LIFE IS JUST TO SHORT TO DO EVERYTHING YOURSELF!!! You have to pick the parts that you cannot get anywhere else and do them well, thats what makes the world go forward.

Our host has devoted his LIFE to the automotive parts business, most of up do not choose to do so, consequently we do not get into the details as much as he does, the same goes for many of the parts. DO you want to devote your life to automotive ignition systems? Or would you just choose to buy one that works?

Hi Jack.

I like fiddling with things, and my time's not worthless. I'm working on my MS implementation because I like it.

John

True enough. If I didn't like fiddling with my own car, I'd farm the work out, but I do enjoy it; particularly that sense of satisfaction when you dialed something in properly by yourself.

I Suspect 350 will get that same feeling by setting up his own maps. Why pay someone else to do something when you can do it for yourself? Workmanship is probably better, you learn something, and you're probably happier in the long run.
