I'm in the process of converting my drag race bug over to EFI. I should have it on the dyno in a few weeks. Here is a link with more info...

Are those square wave cam and crank sensors? If so, can you tell the source, are they the LSx sensors?

The 3/8" diameter sensor pictured, two wire, is a "VR" type with internal magnet.

The GM Gray 90 degree sensor (58x) is a "HALL" for the phase sensor. (camshaft, rocker arm, etc.)

I finally started it up today! It may be another week before I have a chance to start tuning it on the dyno, but at least it starts, idles and free revs.

I'll update when it is tuned.

Hi Jeff, did you make changes in the "pre-calibration" OR did the engine start and run with the shipped calibration ?

The O-Berg oil filter is great for BIG ROCKS but will plug very fast, go into bypass..

I use this type of filter for inspection of the engine, then a "fine" paper filter before the oil enters the engine.

I am using the two stage O-Berg. It has a course screen first then a fine screen.

Lance,

I went into the configuration table and set it up for the firing order and number of cylinders that I have. I set up the coils to fire with their companion cylinders... until I get the cam/phase sensor hooked up. I also set the span of the TPS.

Other than that, I gave it a try and it fired up almost instantly! I ended up having to pull quite a bit of fuel out.

Once I got the thing to idle, I adjusted the timing offset. With having to cut the keyway for the pulley and modifying the crank angle sensor bracket to fit my waterboxer case, I ended up having to put 6 degrees in that box to get it spot on.

I'm going to play with the fuel map a bit more before I start the steady state tuning. I should have a decent tune on it within the week.

Thanks again and I am sure I will be calling you soon!

Oh yea, also yesterday, we had our pre-season tech and chassis cert here in Spokane, WA. My chassis is re-certed to 8.50.

Hi Jeff

Thanks for keeping us up to date with your conversion.

On your web site you state that you intend to make switch fuels to see what effect this has on power. Do you intend to use the N2O at all during these tests?

Roger

Eventually.

Things may change, but at this time I plan to get the best tune on VP C-14, then C-16, then C-16 with nitrous.

After that, I want to try ethanol without and then with the nitrous.

Ideally I need to make a couple changes on the engine to get the best out of it though.

Hi Jeff, the '882C EMS you have can "find" phase without a cam sensor.
This will work, always, when you fire the coils "waste spark".
The CAS is a better "hard wired" solution, so use it when available.

My advice is to create a "phase" for the Injection Instant, each cylinder.

Example: The #1 (one) cylinder could be able to be fed fuel at a time of your choice.
This is important at a LOW injection duty cycle time.
My choice of that event period is when the air flow is higest for each cylinder.
The most common phase event start is from 390-450 degrees.
Then the "event" is advanced by the ECU as is the "Spark Instant".

Okay, I am even a little bit closer.

Here is a video of me starting it today and free reving to about 8,000 rpms.

I still need to do a little more work before I get some dyno pulls.

By the way, you can see the snow flakes blowing into the shop!

Looks good. Neat project.

BTW, if you added 6 degrees to the timing offset, it means you are off by one full tooth. It's probably better to change the tooth count BTDC in the config screen by one, and have a 0 offset.

Finally got a chance this past weekend to strap it down on the dyno and do some more tuning.

Here is a video.... Click here for video

As you can tell, I did my tuning in third gear. (It is a four speed) Also, I did the pull from 4,000 to 7,500rpms.

I have the air fuel ratio where I want it and the timing too. Only problem is that the HP is down from when it had carbs, so first I am going to lengthen the runners and if that doesn't bring it back, I may have gone too big on the diameter! Oh well, once I hook the nitrous back up, I can make up for it!

:)

Lance,

How can you find which cycle the engine is on without a cam sensor?

PostPosted: Wed Jun 10, 2009 9:45 am    Post subject: Tooth Acceleration Measurement Reply with quote

We use tooth acceleration measurement to determine when a cylinder is
on the compression stroke or on the overlap stroke.

This measurement is most apparent during the start-up event.

This ability of measurement can only occur when processor decode speed for the target wheel is over 100 MHz.

It's crazy how fast time flies! With all of the budget cuts, the dyno at the college was off limits for the summer until a couple of weeks ago. I finally put it on the dyno with the stack extensions and it made about 8 percent more power with them. I am back at the same peak hp as the carbs, but still down a little on peak torque. I really think when I get a chance to play with diameter next, I will get it all back, and maybe more.

http://www.badbugracing.com/BB2-9-19-09.wmv

Unfortunately with having to focus on the family and work, it won't make it to the track this season. My new goal will to be ready for the first race day next spring. I should have everything dialed in and ready.

Oh yea, I put the airfilters back on too!

I haven't posted on this thread in a while. Do to time, money and my wife's health, I haven't done as much with my bug recently as I had hoped. However, over the last couple of years I redid most of the engine and just finally got a decent tune on it this past weekend. I still need to dial it in a bit better as I kept it on the safer side, but to the rear wheels on a Mustang dyno I put down 433 hp & 376 ft/lbs of torque. Cool

Here is more info on the new engine...

http://www.badbugracing.com/2015_Engine.htm

I'll update again after I am able to make it to the track. Twisted Evil
