LOL

Yes the Porsche is my moms car, its a Boxster, how much more of a girly car can you get? Though I must say, it handles really freaking well, its kinda fun to drive

My rx8 is my easy going economy car I guess? Though it handles like sex on wheels, I cannot stop grinning when driving it. The rx7 is just my uhm... project car to play with and beat around on. I need to move out so I can get more cars, I'm out of space and want more!

 

bump

 

Bump what?

 

have you diagnoised the problem yet?

 

Seems so as of today.

Spark is working on the test bench, and next week I'll get a chance to test it on the car to see how it does at this point.

 

yep, I left the LED's out before because the signal looked the same on the oscilloscope with or without them... but it appears that it is necessary to have the LED's in..

Got it sparking so much that the smell of the ozone made me dizzy

 

so you just soldered the leds in and tada magic?

 

I don't know about tada magic, but yes it worked after I soldered them back in and redid the pullup resistors.

ddub's megasquirt was the first one I tried without the LED's, and I didn't have an extra ignitor/coil to test with (and the circuit experts on the megasquirt forums didn't think it'd cause a problem to have the LED's out, and neither did I), so I went ahead and did it that way.

Now I know they're necessary, and why they're necessary, so all of my megasquirts from here on will include them (no brainer).

 

Ken (muythaibxr) has been great through all of this, I must say. For someone doing this on his free time as a side business, not his livelyhood, he sure has been helpful. He's been there for me to help troubleshoot over the phone, on AIM, and willing to do so much with fixing to get me going again.

Anyone thinking about buying a Megasquirt and Spark that doesn't want to build it themselves, seriously contact muythaibxr. Not only do you get someone that has been through a lot of the troubleshooting, building, and fixing of these things, but he's one of the nicest and most helpful people you'll find

 

I'll remember that .

I got a question, is it true that there will be a MS 'n Spark that will plug into the factory harness?

 

yeah, I got a prototype mostly working today... just have to add support for the fuel pressure regulator solonoid... I ran out of some of the parts I need for the circuit to do that... Other than that it works great. (well as well as it can considering all the grounds and the coolant temperature connector are shot on my stock harness... After I fix those and actually drive around a bit, I'll consider it "ready").

I'll take some pics of it when I get a chance.

 

It started today

Idled just fine, got some good videos and pics that will be posted later tonight when my friend can send them.

Long story short it idled for about 30 min total while I was monitoring and checking things. I have a few issues I need to work out before I feel comfortable to drive it, but it's running

AND LOUD AS ****!!

 

Congrats man, cant wait to see vids

 

congrats! post some vid !

 

Vids will be here soon, if my stupid friend would get home already

Forgot to mention before. Here's an interesting little story...

So it was massively flooded and wouldn't start. To unflood it I removed the fuel pump fuse and began cranking. Upon doing this, my friend checked my mechanical fuel pressure gauge to make sure it was indeed not flowing any more fuel. Yep, it was at 0psi now when normally it'd be at ~35-40 during idle/cranking. So I knew no more was coming from the tank at this point.

About the 7th time cranking to get the fuel out of the engine, it starts. OK no problem, it'll burn up all the gas and die once its unflooded right? Wrong... 30 minutes later, it was still running and the fuel pump still had the fuse UNPLUGGED. Fuel pressure still read 0psi since the pump was unplugged, and the car ran fine. It was showing 14-16:1 afr's the entire time at idle, also, which is kind of lean. But amazingly, it was idling pretty solid at 1100rpms after firing it up for the first time. Crazy huh?

So, my car likes to run off no gas I guess? If anyone has an idea as to HOW this happened, let me know. I've asked a lot of people, and they all think I'm lying or crazy.

 

demons

 

You're car is the frickin' antichrist, it runs off of hatred and suffering.

 

Videos are coming in a couple minutes...

And for those wondering, the camera somehow lost like 10-20dB, believe it or not it is even LOUDER in real life

RXSevenSymphonies can vouge for that, he was the one taping.

 

I think it lost more like 100db

 

OK, video time for those out there.

First one. This is where my car started for the very first time, but I set the idle much too high initially and it was at 3800rpms right off the bat. So I got kinda iffy about it and turned the car off, because to adjust my idle it takes a while.

Now for the proof my car hates gas! This is the second startup which I did with the fuel pump fuse OUT so the fuel pump was off. After it got going I went to plug the fuel pump back in because I figured it'd die soon. Plug it in, sputter, boom... car died. Interesting...

http://home.comcast.net/~drewrx7/videos/boom.MPG

And now for the best one. This is when idle was set better, around 1100-1200. The fuel pump fuse was OUT the entire time during this, and then for another 25 minutes or so after the video ended. Ran the entire time, 0psi fuel pressure, fuse for fuel pump disconnnected. I'm clueless?

For those wondering, or if anyone actually cares, that's me in the video in my black innovate motorsports sweatshirt RXSevenSymphonies is taping and you can hear him talk a couple times I think.

So that's it, the saga is almost complete, finally! Now to start working out the bugs and begin tuning! Eventually I'll have a dyno too

 

dl'ing the vids now.. cant wait


as for running w/o the fuel pump, the vacume from the engine w as actualy sucking the fuel into the engine. I run a wolf3d and under heavy decel.. like pegging my map sensor to 83kpa vac+, my my engine will richin the hell up.. like 11.5 or more at high rpm till the vac comes down a bit.. crazy

 

Wow.. vids are freaking awsome.. the idle @ 1k with the smoky exhaust looks badass

 

I thought about that too with the fuel. But... would there actually be enough fuel in the rails/lines/system to keep it running for 30 minutes? The fuel pump fuse was out the entire time for the last idle, so it was not pumping anymore fuel into the engine. Plus my car was on a slight downward slope, so the fuel couldn't have somehow flowed up on its own



Oh yah, also another side note. That's my RX8 jumpstarting the FC I was doing so much unflooding/cranking, I needed to have a running car hooked up to the battery to keep the thing charged haha.

 

ahh man, congratulations.

cant wait to hear some driving impressions and maybe some dyno numbers!

keep us up to date on the tuning of the megasquirt.

 

good job it finally runs, now to fix all the little things
