What would you like me to log for your viewing pleasure...?? I'll use the datalogger hardware/firmware that I built (MMCdroid) with the software that I wrote and hopefully we can get that train wreck on here.

Aaaaand THIS is why I don't post on Tuners anymore.First off, you don't use TunerPro to view logs. Secondly, my fuel trims are -4%, -4%, and -2% (as. I. said.) The voltage for my "hacked up O2", also known as an AEM UEGO in P04 mode, are cycling precisely as they should with corresponding less...

I did forget to mention that the regulator from my (3000GT) VR-4 is an Aeromotive AFPR.I really don't understand why it's hard for you to get that outside of adjusting cruise AFR's and fuel trims, both of which only occur in closed loop, the stock O2 sensor does absolutely nothing - and that...

Yes. I did. That's why listing mods is pointless - there are no mods. As I said, I listed the mods I had done, and also listed the mods I've undone (which was everything). I don't know why it's so hard for you to follow that without looking at a profile. Here's my profile: Stock GVR4. It's...

Stock turbo, stock intake, stock MAF. If BOV was vented, it would (at worst, if it leaks) cause a post-turbo boost leak, which would cause me to run rich under boost.The only reason I don't believe it to be an exhaust leak is because it has no bearing on acceleration... you can literally...

I can repair it that if it requires it for less than you would spend on an EPROM. However, you may want to try just cleaning the board up with acetone and a toothbrush (which will remove the conformal coating) and soldering new caps into it. Test it and see if it works.There's likely nothing...

An EPROM chip can do everything I want it to, since I program in assembly. I can do way more than ECMLink can dream of because I can add and remove code as I wish. In addition, all AEM UEGO widebands have a Nernst emulation mode that's turned on by rotating the calibration dial on the back to...

'92 GVR4. I put 720's on it and an EPROM chip I burned. Was running great. I put a wideband in place of the narrowband set on simulation mode and hooked it to the ecu. A couple days later, it starts running lean under boost and rich at cruise. I immediately think "air leak prior to turbocharger...

Yeah, pulled the head today... redoing the valves.

Which is exactly what I intend to do at this point... either grind the cam lobes, or grind the lifters; Could also grind the roller on the rocker. :-P All of these options would yield my result... lifters are the cheapest option, though, I believe. We'll see what happens. And no, none of the...

So today I replaced the lifters/rockers with known good ones out of an old 1G head. They were my first suspect. Cylinder 1 still has 30 psi of compression; no change. That means that either the springs are too weak to pull the valve closed the whole way vs. the hydraulic lifter (unlikely), the...

To the best of my knowledge, they're stock cams... I, personally, have never messed with them. However, who knows when it's a DSM with however many miles on it....

Lifters were all bled prior to installing into the head

Timing is on. Cyl 3 has 140 psi.

I just finished putting together an engine for a first gen... The head is not known good, thought it passed a hydro test while on the bench with the cams out of it.Cylinder 1 has only 30 psi of compression. This was weird to me, as it passed the hydro test and the rings are new (I expected...

The Original Symptom: Car ran like crap. Has no power, can barely rev. Freshly built engine with good compression, literally zero miles on the build. Hooked up my logger, had 43 counts of knock while driving. What I've tried thus far: I replaced the fuel pump first - it seemed to me that the car...

For both of you... you have "enable persistence" unchecked, correct? Also, do you have Rev. D of the adapter? It will say on the board if you do. I barely attend this board after my thread got shut down, I apologize.

Correct - but that's why I'll also add an option in the menu to choose which sensor you have ;)Also... you have to be careful with widebands. The most common place to put them is in the downpipe for two reasons: 1) they are not very heat-tolerant. Placing them too close to the exhaust stream...

You can log the WBO2 output as well. Connect the voltage output pin of the gauge to the EGT input pin on your ECU. I'll sort out the formula for it next software update :thumb:

Hey guys, sorry for all of the confusion. As Bud previously stated... I came down with the flu, which turned into pneumonia. I have chronic bronchitis, and was hospitalized. I was released today.I attempted to use my knowledge of the matrix and plugged the hospital phone into my ear canal...

You haven't gotten an email? Did you type your address right...? Because I copied them directly from the sign up sheet to the "send to" box.

....check your email if you signed up for the group buy and weren't the "jbauer" guy that didn't provide a domain for his email.

That's the difference. Also, one thing you CAN'T log (which is.. uh.. kind of important) is knock sum.

No, it's based on the number of people signed up. 45 people are currently signed up, so it's at $46.18

38, last time I checked (a few days ago)

Sure, but you can't log knock (or anything *REALLY* useful) on OBDII :-P Also, there's currently a group buy going on for the hardware that will end on the 31st - might drop the price down to around $45. https://docs.google.com/spreadsheet/viewform?formkey=dEltM29zS19peHptRl92NHNiLTdlb0E6MQ

Um.. kind of. Have you ever taken a science class?? Everything expands the hotter it gets. Gasses become less dense (read: less molecules of that gas in the same size square cube) as they get hotter.The thing you'd be looking at is air DENSITY - cooler air is more dense. More dense : more...

The software is lookin pretty free right now.

Doing testing today, hopefully shipping the first batch out tomorrow. Here are some pics:The third image shows a request-reply on the oscilliscope - the left waveform is a request for voltage, and the right waveform is the reply of 11.98v from the ECU. Also shows a comparison of the old...

They're for sale now. Obviously you need an android-capable device with bluetooth, though :P

If you were on a mailing list, or had sent me an email in the past, you got an email. If not, twelve version 1-style units are available for sale at FrozenApps.com on a first come, first serve basis. I am currently in the process of revising and testing the new version as it has a few bugs - but...

Today I finished re-designing the PCB. I've shrunk it down to about 1/3 the size of the model that I have. I sent the files off to be prototyped, and should have my copies in hand within a few weeks. After everything is confirmed working properly, I will do an initial run of 100 boards. I also...

STATE OF THE PROJECT ADDRESS*****UPDATED 01/11/2012*****So I'm sure a lot of the fervor and anticipation has long since died, and perhaps some people were still holding on with a thread of hope. I've been silent for a long time, there have been no updates, etc. So, I've decided to relay...

What's your email? I may be able to find one somewhere on my hard drive. It's changed a bit since then though :P

Well, the way it's going now, it's going to be a USB cable. The bluetooth hardware exists, and works (as I've demonstrated), but because I'm not the one that made it I have no control over that. I've successfully gotten my USB adapter to communicate over serial with the ECU, however, and just...

This is *not* dead. I've run into a huge lack of time lately, though I leave for the military in about two months so I will be resigning from my jobs in order to focus on my family and have a little free time before I have to leave, and this project is one of those things. Stay tuned. Also, not...

Might not be able to play on max settings, but does that actually matter somehow...?? Last I checked, I don't play video games for graphics (which is why I still play quake live, counter-strike, StarCraft, etc....) and I can *STILL* play any new game at nearly max settings.As for the dude...

That was a valid argument about 10 years ago... however, two years ago I dropped about $300 on a new motherboard with decent onboard video, 4 gigs of 1ghz RAM, and an AMD Phenom 9950. I still get 60 FPS in whatever game I play. Where is your argument now??? I paid less than the cost of a stupid...

Hey, guess what? There's this thing called PC gaming.. and if you're playing first person shooters in any other way, you're wrong. Best part is - YOU ALREADY HAVE THE SYSTEM TO DO IT! Win/win situation!

Well.. umm... thanks? One question I do have is whether anyone knows if the power is an output from or input to the ECU. Obviously if it's an output, it's an ECU issue.

Alright, so I got the car running today (finally) after putting a 6 bolt into an unknown shell (wasn't running when I bought it). I also have a MAF translator hard wired into the ECU. So the engine runs.....However, I have no dash lights, no power to the constant 12v on the radio, and when I...

Eh... my better judgement says no. Unless you have a pretty decent serial convertor (I saw one that supported the baud rate, but I can't remember where, and it was fairly expensive.) If I haven't personally tested it, I don't want to tell you yes, essentially. You're welcome to try it, however...

Anyone have a 2g GM MAF-T that they can take a picture of...? I have a 1G MAFT but have switched to a 2g, so I need to know which wires go where on the plug. So basically.. just need a pic of the plug on the second gen MAF-T so I can hardwire it into the engine harness.Anyone?

I just stopped answering because it wasn't up to me... I'm not making the hardware, as I've said a few times.. it's up to the guy who's making it. He says he's going to put out the first 14 this weekend. However, at this point I wouldn't be holding my breath (as I have been.............)Trust...

Wait wait wait.. before you buy an OBD2 adapter, realize that I don't have hybrid support yet and the generic OBD2 adapters may not work. I haven't tested anything at this point for hybrid.Requires learning a new programming language (most likely), a new API, and then building the program...

YouTube - MMCdroid: The software, the hardware, the wreckage!!Hybrid support soon because my 1G got smashed to hell and I'm putting the engine into a 2G :P

I'm going to start working on hybrid support - but I need your help. Does anyone know exactly what hybrid OBD is? I recall reading years ago that it was the same as OBD1 with an OBD2 port.Does it have the same baud rate as OBD1? Does it work the same, where you send the address byte you want...
