First pic's of my CIS to EFI conversion on 2.7 Turbo using Tony's kit
 

I just wanted to post the first picture of my winter project. I am using Tony's EFI kit on my 2.7 Turbo (Modified BAE kit). I just started it up and it seems to be running good. I will hook up a laptop this weekend and see how she runs. I am going to send the pic's to Tony, his kit went together very well.

Looks great Oscar - very clean install.

Looks great Oscar! What a clean engine bay.

This is breaking new ground on simple, cheap turbo conversions for the 911, with modern fuel injection control.

Give me a shout for any tuning help.

Cheers,

oooooh....looking forward to following this thread! kudos, oscar...gonna have before and after dyno numbers to report? what mods did you do to the bae kit? is that with a k27 or k28?
ryan

keep us posted

me next! this summer!

very interested in how this turns out!

might need to steal the map from you so i can get a baseline to work from.

GOOD luck!

I am using the original Rajay turbo. I modified a set of BB headers(shortenned them). and custom made a crossover pipe with Flowmaster muffler. Installed Wastegate and MBC. The biggest problem's I think I am going to have will be tuning it. I know very little about this part.

Oscar

Wow the air box mod looks great! I was thinking about installing Tonys Megasquirt on my 79SC, now Im wiping the drool off my chin. Clean and very impressive looking. I hope we get some dyno#'s. I'm still concerened about tunability.
SWEEEET.
Mike

It sure "opens up" the engine bay.

I got one of the g-tech pro gadget's for xmas I am going to see what it will do when I get it on the road. Unfortunately I don't have dyno numbers from before.

Oscar

That looks great keep us posted on performance #'s . Engine bay is very clean.

You should get a wideband O2 sensor to help with tuning. Most have an output that you should be able to log right to the megasquirt and use those values to help set your fuel map.

Oscar,

How about more pictures....we love pictureshttp://www.pelicanparts.com/support/smileys/wat6.gif

Plenty of room for an intercooler in there and no need to run a turbo tail :)

Where is the turbo sucking air from? It might be worth routing the filter into the compartment too.

Exactly what I was thinking. It would be pretty cool to slap a big V8 water-cooled intercooling block on top of the manifold and run its heat exhanger on the air intake grill on the rear deck (like the old A/C exchangers used to). That would really make that intake charge cold. You could bump that manifold pressure waaay up.

Great install! Now get yourself WBO2 kit for tuning and you'll be fine.

More pics! How about the exhaust + housing mounts. Very Clean install btw.

tell us more about the intake plenum.

is it all aluminum, or did you make a plate and attach it to the stock plasic lower part of the airbox?

wow, that is an insanely clean engine. Any thoughts on if tony's kit would work for a factory 3.3 930 motor? that would be a great way to improve the gas mileage on an older turbo! possibly kick up the hp and torque a notch also, i think!

I fabricated the airbox from stainless plate, 1-1/2" pipe for the runners, a tig welder and lot's of beer. The airbox was probably the part that took the longest. I will get some more pic's posted. I have all the parts for the intercooler, but I want to get it running and tuned prior to installing it.

-the air comes in at the turbo, I installed a 3" cone "K&N" filter right to the turbo.



AND WHAT THE HECK WAS I THINKING THAT I WOULD BE ABLE TO TUNE THIS MYSELF.

I just hooked up the laptop to it and have no clue what I am doing. I am going to call Tony tonight to walk me through it. Fabricating and the "grunt work" is easy, but computer's suck

Oscar

Oscar,

Tuning isn't really that hard once you've gotten a bit familiar with the software tools.

I'll email you a base map with some rows in the VE table having positive manifold pressure (ie: boosted). What fuel pressure are running? (ie: is your fuel pressure regulator 3.0 bar or 2.5 bar?).

Did you install a wide band O2 sensor, the narrow band O2 sensor?

I'll email you off line.

Cheers,

Tony

Also how much boost is your wastegate set to cut off?

tony,
I am going to set the wastegate to 7lbs. I am using the MSD Regulator that we had talked about, I think it will go to about 40 lbs. It is set at 30lbs at idle. I am using the 3 wire heated MSD sensor from Summit. I am pretty sure it's narrow band. I think my biggest problem is that I am not the best with computers and know very little about tuning. when people say VE table... I am lost. I am going to have to learn more. The car seems to run good, starts right up. I think it run's ritch when it warms up,( I say that only because the graph on the bottom of the megatune that goes from green dot's to red dot's moves well into the red as it warms up.

Thanks
Oscar

Oscar,

Pull the vacuum hose off the fuel pressure regulator and read the fuel pressure. With the vacuum hose on the FPR it is automatically compensating for manifold vacuum so we don't really know what the fuel pressure really is.

Tony

Tony,
What should I set it to w/o the vaccum hose? also, the car at idle, right?

Oscar

Tony, do you know any of the coders who writethe tuning software? I am a user interface designer by trade (I work for a monopoly, guess who). I'd love to work with those guys to make the interface for MegaSquirt kick the crap out of the proprietary EFIs.

I can't recall if you are you using my 30lbs/hr injectors? This will dictate fuel pressure.

Tuning software is called MegaTune and is written by Eric Fahlgren. It is very professional. You can download rev 2.20 from here:

http://not2fast.wryday.com/megasquirt/mt/2.20/megatune220.zip

Source code is here:
http://not2fast.wryday.com/megasquirt/mt/2.20/

Yup, I've checked it out from the MegaSquirt BBS in the past. I wish I was a coder, I'd love to hack around on it. It is indeed very professional; it has all the bits and is pretty darned cool all around. That said, it still isn't intuitive to the novice user, thus our associate's problems. Usability is my forte. I'll give Eric an email and see if he'd like to share some thoughts.

Oscar,
Great work! Keep us updated!

Tony,

I am using the 30lb injectors

Ok then.

With a fuel pressure of 3bar (43.5psi) you're good for 280Hp
With a fuel pressure of 2.5bar (36psi) you're good for 255Hp

The only negative thing about running higher fuel pressure is you're idle pulse widths maybe very small. So if you think you'll never go beyond 255Hp then stick with 2.5bar otherwise go to 3bar fuel pressure.

Tony

The BAE kit back in 77' said that it would put 259 hp. I have no clue where I am now. Now, are you saying that the max pressure should be 36lbs, or that at idle w/o the vaccum it needs to be set at 36lbs?

If BAE say it can go to 259Hp then go with 3.0bar (43.5psi) fuel pressure.

You need to do this with the vacuum hose removed from the fuel pressure regulator and the engine idling. You will probably have to turn the fuel pressure adjustment screw all the way in to get 43.5 psi.

Note this will richen your mixture because the current MegaSquirt configuration I have supplied is set for a fuel pressure of 2.5bar. I'll email you a new configuration file.

Tony

note: you don't really need the engine running, but MegaSquirt shuts off the fuel pump if it detects the engine has stopped.

you can always just unplug the MegaSquirt unit from the harness and then turn the key to the "run" position to keep the fuel pump running and make your adjustement.

Since the engine is not running in this case, you don't need to remove the vacuum hose from the fuel pressure regulator because there will be no vacuum.

Tony

no problem, I will set it this way. I had it turned up this way when I first started it by mistake and even I could tell that it was running ritch. what you are saying makes sense. When you email me the files I will have to learn how to imput them into the car.

Thanks

Oscar,

Very nice work. Get yourself a wideband sensor setup like this one http://www.innovatemotorsports.com/xcart/customer/product.php?productid=16169&cat=253&page=1
Swap it for your sensor, connect the wires, change a parameter in megatune and it will make your tuning tons easier.

I'm also running a modified version of Tony's kit on my 3.0 carrera

I'm running a 6cyl wasted spark EDIS with megasquirt2 and an innovative wideband sensor. Supply and return for the turbo is ready. All that's left is for me to get the nerve to remove my heat exchangers and install headers and turbo. I could also send you my VE Map to compare it with Tony's. Wish you were closer to Chicago

Will,

Can you PM me some info on that EDIS setup. I want to do the same to my 2.7, but am still confused about all I will need, and wiring diagrams.

Tony- do you have any MSII systems, they (MS) say they are not available until July/August.

I don't have any MSII units. You don't need MSII to run EDIS. Check here for details:

What will the Wideband O2 sensor do that the normal one won't. Also what is EDIS?
