this mdm100 is hot! rpms, timing,fuel mixture,sensor ohms and voltage for all diagnostic sensors , speed and more from a digital screen while you drive.definitely worth the money. tuning andfixing stuff won't be a problem now.chipped in with two guys 1 gti-r motor,1 100shot nosmotor,& my 50 shot motor easier on the pocket

Wassup man, u think u can hook that shiet up to my car netime? Prettywhite told me all the turbo car had knock sensor or oxygen sensor problems at the convention and i wanted to c if i have that prob too.

it's good for all nissans too. I guess so for a small fee and we'll even hook up the tuning idle etc. not bad for a couple of bucks cheaper than a diagnostic for sure. we decided to make this bitch pay for itself hehe
come around any time.

Sorry to burst your bubble, but the Techtom MDM-100 can only work on '91-'97 model year Nissans. I should know, I have one for my NX, but it didn't work for my '98 SE-R as well as a few friends; one with a '99 G20t and another with a '99 Sentra SE-L out here in the Bay Area. Even G-Force Engineering (U.S. Techtom distributor) told me this, as well. Come on, Jordan... Get yourself a '95'-97 JWT ECU, and not only will you be happy with the extra performance jump, but the Techtom will then work!

I am very very soon. Within a few weeks. I have to get the 95-97 ECU, send it to JWT to be reprogammed, and then rig it up to work on my car. Very very very soon.

How much does this device cost, and where did you purchase it from?

Ack, that's an awful lot of dough... APEX-i apparently has a diagnostic multimeter as well, but I'm still searching around for information/pricing on it.

Any idea when (and where) the next NorthEast dyno tuning day will be? Maybe we can have one of these devices available somehow. I'm in serious need of some tuning...

damn I didn't know it's good till 97. but oh well already did the timing perfect. and other stuff.we'll probably bring it to e-town some day during an event so we can plug and play as long as they pay ( very cheap price). best money spent if you think about it timing light $40, multimeter $40, and other stuff all in one little ten second install ad no more checking sensors for voltage and ohms.

Just to present an alternative solution - searching the SE-R National Mailing List Archives, supposedly there is a PC based software solution known as "Ease Sim":

http://www.easesim.com/

They apparently have software for all OBD2 complaint vehicles.

Now that I think about it, with the appropriate adapter, and knowledge of what pins send which diagnostic values, it wouldn't be very hard at all to write a small piece of software to read the data...

The only thing is I thought it only displayed what the ignition timing is supposed to be and not the actual realtime ignition timing. Lemme go check:

Thats what I thought unless it is actually otherwise.

Just to be sure I checked the archives again as I was seriously interested in a MDM100 since last year but here it is again:

Pretty White: You are correct aboutt the ignition timing readout on the Techtom. It reads the ignition timing that the ECU gives as you move up and down the rev range, however, it does not compensate for mechanical advancement from the distributor. At idle, it will always read (or very close to) 15 degrees. However, that readout would be a good indication of what the ECU is doing to your car, as well as to make sure if the car is in timing lock mode while you're trying to advance the timing (if it's in lock mode, it should be dead on 15.)

Before anyone else asks, if the ECU were to compensate for mechanical advancement, not only will you be able to see it with the Techtom, but you also won't gain any power through it because the ECU would be compensating for that timing advance with more or less fuel, thus rendering timing advance useless.

We used Redman007's MDM 100 last night at our last minute geekout at Roll-Mod-L shop *(see Northeast section). Friggin awesome. Friggin Awesome. I just wish it had more features like the Consult. But nice to measure voltages in sensors. My fans do kick in at 212°.:)
