Okay, lets try this post again (my 1st attempt didn't show any text... in fact, it didnt' show my message at all, so I couldn't go back and edit it anyways)

I just mentioned this piece in another thread and I got a little curious. Does anyone have this product yet???

For those of you that have never heard of it before, it's an LCD display capable of showing any two of the following parameters:

a) vehicle speed
b) engine speed
c) ignition timing
d) injector valve timing
e) O2 sensor voltages
f) airflow meter voltage
g) intake air temperature
h) water temperature
i) throttle position
j) a/c switch
k) idling switch

It plugs into the car's diagnostic port under the dash and can be mounted on top of the steering column.

You can read more about it at www.g-force-engr.com/mdm.html

 

Some forth gens have it. Pretty neat device, IMO.

 

I reprinted this info from an article in Turbo Mag that appeared in August, 1998:

The MDM-100, available through G-Force Engineering, will not alter any of the programs in your ECU - you cannot erase or misprogram anything. To bring the MDM-100 on line, find your fuse box and remove the cover. Locate the diagnostics port and plug in the MDM-100. Start your engine and the MDM-100 will come to life. The unit allows viewing of two parameters at a time (the exact parameters and the manner in which they are viewed are outlined in the chart found by clicking on the image of the Techtom). Pushing the Select button will display an arrow next to the upper readout. Pushing the Select button again moves the arrow to the lower readout. Pushing it a third and fourth time allows the user to add or subtract from the readout's contrast and dimness. With the upper readout selected the Up and Down buttons allow the user to scroll through the parameters. The same parameter cannot be viewed on both readouts.

G-Force Engineering can be contacted at:

G-Force is the exclusive distributor for Techtom in the US.

I've got three questions regarding the MDM-100:

1) Will the MDM-100 plug directly into the Consult port?

2) How much does it cost?

3) Where can it be purchased?

I'll give G-Force a call today and post their response in this thread.

 

1) Our Consult port is different than the 4th gen port, so I have no idea.

2) I believe $400-$500.

3) http://www.techtom.co.jp/index3.html

Sounds like a neat device. But, I think I would want more mods instead for that kind of money....

 

But you can use this device to tune your car for more hp. Not necessary for NA cars, but it would be a nice gadget to have.

 

true....I guess if I drop 4k into a SC another $500 or so for one of these would not be too bad

It's incredible what comes up when I actually bother to use the search function.

Guess we can forget about the MDM-100.

 

So you can use this thing to tune your car?? I thought is was some kind of glorified display to monitor the car.

 

It may be a glorified display to monitor some cars, but not our cars . . . at least not through the Consult port.

 

2K Consult port is different, as experience by Adam, Turbo95Max, and myself. I didn't know if there was an adapter or not, but Adam confirmed it with his Techtom experiment.

What if they made an adapter? Hmmmmmm....

Yes, you can use the results and tune your car accordingly.

 

Hey that is cool!! Sounds like it would be more practical for cars that have SC's and NOS. Is it really worth the cash though? I mean assuming you have a car that is N/A, this wouldn't really help you out too much, right??

 

Heheheh... It won't work.

 

That would be a nice tool if your going SC or turbo and want to know if your timing is being pulled back or if your injectors are running the ragged edge.

I think the Apexi AFC shows some but not all of those parameters.

 

Black plastic (normal):


Faux carbon fiber:


I sold out my stock in these but I can always get more

The AFC shows engine RPM, throttle position/percentage, and mass air flow voltage.

For the Techtom, the more useful items would be air intake temp and o2 sensor voltage.

I'd like to test out a CAI vs cone intake and the air intake temps.... we can finally settle the debate as to if/how much colder the air is from a CAI at speed.

 

That has already been done on the Yahoo club maxima board. There was a big discussion (agrument hehe) as to which was better. IIRC the SI had more MAF voltage at high rpm than the CAI did. Unfortunatly the yahoo board doesn't have a search engine, nor can I find the post using search on this site (WTF? ).

 

will NOT work on a 5th gen, and I think the 99 edition as well. I purchased one and the port is different. But those things are awsome,it reads all the stuff you need. in one small screen. Its also very accurate, great piece of tool, if you know how to use it, and if it works on your car. I wish it would have fit on the 5th gen, I would not have needed a A/F meter, pluss it telle injector rate or pulse. Its really cool. and it looks clean, when installed properly, Don, and Loren both have one in their 4th gens.

 

I received a pinout of the Consult-II connector from Dave "The Man" Burnette at Southpoint Nissan. I faxed the pinout to G-Force and will call them next week to see if they're willing to make a connector for 5th Gen Maximas.

Stay tuned.

 

Its a cool device, but it only monitors parameters. you cannot adjust them using this device. I've had mine for a few years.

I seriously doubt the consult connector could be swapped then the MDM-100 work. It reads from the ECU.

Here's a few pics of mine installed in my car. I made a custom dash for my stereo and MDM, and have room for "other" controls in the future.
**** Just for reference, the Water temp reads 184 (AC on, fans running) & the Inlet Temp reads 117 degrees. That was Idling in my driveway, for over 20 minutes, in July heat (110+ in Houston)... At speed (cruising) it stays around 100 or so on hot days, cooler days it averages 85-95. I've never seen it below 54, even in freezing temps . With A/C off, fans will come on at 204 degrees.

 

Yes indeed. Sounds like that 4th gen guys would have to do the test though.

 

Perhaps, and then again, perhaps not. According to Tadashi at G-Force, only three signals are needed to make the connection to the MDM-100 -- Tx (Transmit), Rx (Receive), and Clk (Clock). According to the diagram I received from Dave Burnette, the Consult utilizes a 16-pin connector. Pins 12 and 13 on the connector are attached "to each diagnosed system". My guess is that one is Tx and the other is Rx. Pins 7 and 15 connect to the ECU. There is no indication as to which pin provides the Clk signal.

I faxed G-Force a copy of the pinout I received from Dave and I live fairly close to their facility. If they're interested, I'd be willing to take my car to them to see if they could hook up an MDM-100 to the Consult port. I'm supposed to call them around the middle of next week. I'll let you know if I make any progress.

 

Is the pinout something you could post here, or is the pinout a super-secret?

 

Don

What were your typical ET's before you started your engine build?

 

It's not a super secret. I'll scan it and send it to you. But you'll need to send me your e-mail address because I can't attach files on our system. Perhaps that will change some day.

My e-mail address is bld522@yahoo.com.

 

with that type of cash, it betta add like10 horsies...i have much betta thing to do with half a grand.

 

If they say it's possible, then you should ALSO ask them about a group buy. I would definitely be interested in one.

Anybody know where I could get a USED one for cheap? I would like to "tinker" with it, too see if I could get it to work.

 

I spoke with Robert at G-Force today. He said that Tadashi, G-Force's Chief Engineer, reviewed the Consult-II pinout and said that it might be possible to develop a plug for the Consult-II diagnostic port. But it will be two to three weeks before he'll know for sure.

I'd recommend that everyone interested in this product send an e-mail to Robert at G-Force. His e-mail address is robert@gforce.com.

Here's a copy of the e-mail I sent to Robert:

I understand that Tadashi thinks it may be possible to develop a plug so that the MDM-100 Techtom can be connected to the Consult-II diagnostic port of a 2000-2001 Nissan Maxima. Please let me know as soon as you receive confirmation of this from Tadashi.

I've taken the liberty of providing your e-mail address to other interested parties. I've asked them to contact you so that you can add them to your list of respondents.

 

Thanks for the update! Robert has mail!

 

I hope more 5th gen owners respond, so maybe we can get another great aftermarket product available.

Next, we should put some pressure on HOT SHOT for some headers for the FED spec Maxs and then CALI spec owners can do a fed-cali conversion thanks to DesertPearl.

 

robert@atagan.com. You can also copy tadashi@atagan.com.

 

Hehehe... yours got kicked back too?

 

Oh yeah!

 

I received the following reply from Robert at G-Force regarding the MDM-100 Techtom:

Correct me if I'm wrong but we spoke by phone right? The programmer needs more time.

This was my response:

Yes we did, Robert. Any idea how much more time the programmer needs? Will the programmer need a 2000-2001 Maxima to use as a test vehicle? If so, when would the programmer like someone to provide a vehicle for testing?

Stay tuned.

 

Yeah, he also said to me that they're working on it.

 

Here's the latest reply from Robert at G-Force. (My questions appear in italics.):

"(1) Any idea how much more time the programmer needs [to make a connector for the Consult port]?

Hard to say. I don't think we can really say. We're looking at moving to a bigger building soon so our R&D is a little behind as it is. It won't be anytime soon. It didn't look very easy. Nissan changes (updates) the COM protocols quite often and Japan can't really help much because the OBD2 stuff is pretty much US only. So the 2000 Japanese protocol is different.

(2) Will the programmer need a 2000-2001 Maxima to use as a test vehicle? If so, when would the programmer like someone to provide a vehicle for testing?

At some point yes. So if you could come to our shop when we get to that point it would be great. I'll save your mail and let you know. Or drop me email any time.

Thanks for the update.
