After reading Aki's great review of the Do Luck DTM II it was time that the aging analogue g sensor was replaced with a more modern and up to date setup. Also at the same time remove the old and trusted Skylab fusion which was one of my first mods after almost losing the back end on my way home from RK :chuckle:

Remove the centre console to access the OEM G sensor:



In my case I ripped out the Skylab also



OEM G sensor removed from the mounting plate:



Do Luck DTM G sensor box mounted with double side tape provided to OEM Bracket



Plugged into existing harness and two wires for TPS routed towards the ECU and another plug for the display
routed towards the ash tray/stereo area.



Locate and identify the purple/grey wire for TPS from pin 56 Brown wire ecu side and orange wire engine side



Next up to mount the small LCD display/Controller





Next step to calibrate the TPS and the selection of modes available: To follow.

Summary of the available modes:

There are a total of 7 settings:

4 in G mode - G1, G2, G3, and G4
3 in ARX mode A1, A2, and A3

G1= Output signal same standalone Do Luck Digital G sensor:

G2= Output signal same standalone Do Luck Tarzan G Box:

G3= Output signal same as a new Nissan oem G sensor:

G4= User programmable - can define a percentage for each of the 4 (front, rear, left, right) G forces should be multiplied by, as sent to the ATTESA ECU. The user can choose an amplification between 0% to 200% for front, left and right G forces, but for the rear G force (i.e. braking), the amplification range is between 100% and 115% (From Aki's Blog)

ARX Mode uses throttle position along side G force and is multiplied by a set variable for each of the settings looked up from the Attesa ECU map.

A1= Street Mode
A2= Circuit Mode
A3= Pure signal mode for both throttle position and G force.

I have a question for you... On my R34 GTR the MFD never shows 100% Throttle...(for a reason i dont know, maybe it needs calibrating?) maybe max like 40-50% will this effect the operation of the DTM2??

The DTM takes the beed direct from the ecu tps signal pin and then once installed you need to calibrate the throttle. Not sure about the MFD. Might need calibration also?

Great I shall look into it. I dont see why it wouldn't work. If i had one complaint about the Screen to the G sensor is that the loom is roughly 6 inches too short :( i had to lengthen the loom in order for it to go under the wash/wipe stalk where I wanted it. ill post some photo's up later this week :D all in all looks a great product so far :D

Yes it does work with all models. Imo it's the best and easy to fit. Depends who you ask.

Ok That's fine. Which Setting do you mean Is the best? G mode or ARX? And use the ARX Mode only the throttle Position or combination with G Signals?

hi, just curious...does this allow you to monitor percentage of power going to front? Kinda like a digital torque meter, like what's on the gauge cluster?

I'm using A2 most of the times its quiet agressive. Just find one that works with you. I also like to map using the tps based input to then give front torque based on throttle position.

No does now allow to monitor front torque.

Sounds like a pretty awesome item though, you can get the best of all DL's boxes or tune yourself. Does anyone else offer something like this (Midori Seibi, Top Secret, AutoSelect, etc)? I was really interested in Midori Seibi's G-sensors, but this has potentially swayed me, specially after reading about the Tarzan box.

The do luck imo is the easiest configurable option. You have full race but fitting is a little involving and it bypasses the attesa ecu.

It completely bypasses the ATTESA ecu? Didn't think that was possible unless you had something like what Full Race offers. Is this fully digital speed? Not analog like factory? Is the ecu analog or does it send/receive analog signals like the g-sensor? If so, if this DTM is fully digital and bypasses all the analog factory stuff, then wonder why this isn't more popular, since it should be super fast compared to OEM.

Or am I way off?

Full race bypassed the attesa ecu. Do luck doesnt. The R32 speed improvement up approx 30 times and 15 times on an R33/34. It's digital

Ah my mistake, I misread your post. Thought "full race" meant a mode of the DTM. Sorry!

I wonder how having something like the Omori Factory ETS ecu from the CRS R34 GT-R would affect it. I can't find any information on it other than what's on their site, but I've read it's been "reprogrammed". Wondering if it's faster than the regular R32/33/34 model ecu's. If so, would there even be a need for a controller? Or maybe still a need but if it's got updated internals, if it'd make using a new G-sensor even better.


ETS control unit NISMO Z-tune specifications, M / C before
